No Comments

Households depend on many home appliances for a comfortable lifestyle. However, each one of these appliances puts a significant burden on the monthly electricity expenses, not to mention the serious environmental harms of using conventional energy sources. At the same time, we put up with the disadvantages of using grid electricity, like unreliable power supply, unpredictable outages, and high annual energy costs.

Consider switching to renewable energy sources like solar. Off-grid solar systems, in particular, are a great energy source because of their high efficiency. Solar energy proves to be the most sustainable and reliable energy that offers a series of economic benefits while catering to your heavy loads.

Let’s understand what an off-grid solar system is and how adopting solar will translate into savings for the next 25 years for you.

What is an Off-Grid Solar System?

Also known as the stand-alone PV system, off-grid solar systems for homes are a remarkable alternative energy source to use in remote locations. As this type of system doesn’t depend on the utility grid, it enables homeowners to become power independent in areas where accessing the grid electricity is costly or impractical. As the grid is not a part of the structure, batteries become a critical component in the working of off-grid solar systems.

The modern off-grid systems are robust and manufactured to survive inclement weather. Your solar installation company will ensure to provide you with a tailored system design tailored to suit the style of your home and can give and maintain a reserve of ample energy output to power your home throughout the day, at night, and even on other days when energy generation falls below the required standard.

Components of an Off-Grid Solar System

An off-grid solar power system is composed of four key components – solar panels, a solar inverter, batteries, and the equipment needed for the balancing of the system.

  • Solar panels and mounting

Solar panels are a major and most obvious component in a solar system. A solar panel is made up of solar cells, which can be recognised as small squares. Determining the size and number of solar panels required is a serious consideration in designing a perfect off-grid solar system for your home. When you have the right number and size of panels, they are configured in series strings, and multiple strings are connected to form a substantial solar array.

  • Charge Controller

This device is responsible for controlling the energy flow between solar panels and batteries, facilitating the optimum performance of the latter. It allows for proper charging of the batteries while protecting them against overcharging. 

  • Solar inverter

Using a battery-based inverter is the industry standard in putting together a functional off-grid solar power system. Picking the right size of the inverter depends on the load required by your off-grid system. A battery-based system not only converts the direct current (DC) electricity from solar panels into alternating current (AC) electricity but facilitates the AC to DC conversion for battery charging.

  • Batteries

In a stand-alone solar system, having a reliable battery bank is indispensable. It is the second most expensive component in an off-grid structure after solar panels. Moreover, you may need several batteries if your electricity consumption needs are higher. There are a few types of batteries available on the market, and an experienced solar installer will be able to guide you towards selecting the right option.

The Working of an Off-Grid Solar System 

Off-grid solar systems are self-sufficient solar structures working independently of the grid. They consist of all the key components, which are solar panels plus mounting structure, batteries, an inverter, and other supportive equipment, all functioning in one single unit to ensure optimal power generation.

Stand-alone solar systems can ensure power is available for critical loads while allowing you to achieve absolute grid independence. Let’s understand how off-grid solar systems work in four simple steps:

  1. Your roof-mounted solar panels act as a power hub where the critical process of energy generation takes place. Solar panels absorb maximum sunshine during the day and convert it into direct current energy.
  2. Then comes the role of the solar charge controller-cum-solar inverter that is wired with solar panels. As the DC power passes through the inverter, the controller regulates its voltage. It also monitors and measures the total energy production of the solar array while ensuring that the solar panels harvest maximum energy.
  3. When there is surplus availability of this controlled DC power after meeting the load requirement, the excess energy gets stored in the batteries, which are connected to the charge controller. 
  4. Now this stored energy is used later on when solar power generation is below the required level. The inverter automatically draws power from the battery bank to run appliances as needed at night and during inclement weather.

Is an Off-Grid Solar System a Sound Investment?

Considering that solar is a huge financial investment that will impact your life for a long time (over 25 years), it’s wise to evaluate the viability of an off-grid solar power system. And for most homeowners, solar panels turn out to be an advantageous investment. With solar energy, you reduce your monthly energy bills, increase home value, enjoy better energy security, and feel amazing about doing your bit for the environment by cutting down on your carbon footprints.

Amongst all these benefits, another key factor is to determine what the sound return on investment (ROI) is on an off-grid system for your unique situation. Below is a method of figuring out approximate ROI for your system.

  1. Determine the price of an off-grid solar system for your home.
  2. Divide this price by your current cost of per-watt electricity.
  3. Divide the figure by the hours of electricity consumed in a year.
  4. This final number will decide how many years it will take to break even on your initial solar investment. If you further divide the number by the solar system’s average lifespan, i.e., 25 years, you will get an approximate total number of times the system will pay for itself during the expected performance life.

If this sounds challenging, you can partner with an experienced solar installer to guide you. They will not only provide a more accurate ROI estimation but also guide you at every step of your solar journey.

Benefits of the Off-Grid Solar System

The biggest perk of getting an off-grid solar system is that installation is possible virtually anywhere. You set yourself free of common electricity problems homeowners face. You do away with unexpected and prolonged power outages as well as high electricity bills.

  • Absolute energy independence

Power outages are the most inconvenient. Unavailability of electricity can sometimes last for hours or even days, depending on the cause of the power cut and the time required to restore the supply. Inclement weather, such as sleet and storms, lightning bolts, and heavy downpour can damage grid-related utility lines and equipment. Such damages can mean loss of electricity across several localities. 

The working of off-grid solar systems is independent of the government grid. It makes your home self-sufficient in producing and storing electricity. Your home will still have power when the entire locality is in darkness due to hours of power cuts. The battery bank in your stand-alone solar system will always maintain enough surplus electricity to power your home when the sun isn’t visible.

  • Reduced electricity cost

There is no denying that solar energy is highly cost-effective in the long run, promising significant return on investment and savings. As finite resources remain the primary energy source and are depleting, sooner or later, it’s going to be inevitable to switch to green energy sources due to the cost and negative impact on the environment.

The initial cost of getting an off-grid solar system is relatively high as the buyer is required to pay for more components like batteries and several panels. However, you can rest easy knowing that solar has a great payback period. Through savings, you can expect your solar panels to pay for themselves in 6-8 years, depending on energy output, the method of financing your solar, etc. Moreover, your system promises over 25 years of cheap electricity, with no monthly electricity bills.

  • Suitable for any location

There are still many areas that don’t have access to the local grid. Thankfully, with an off-grid system, you don’t have to depend on DISCOM companies to power your home. The system is the best choice for homes in rural or remote locations, which either can’t access the government grid or suffer from intermittent and prolonged outages. Regardless of where you are, if the sun shines on you, solar can be immensely beneficial for you.

Regardless of the off-grid solar system prices in India, these systems are worth the price if you are looking to achieve absolute energy independence in a remote location. 

Facts About Off-Grid Solar Systems for Home

If you are considering a cost-effective, eco-friendly way to power your home, switching to an off-grid solar power system could be a smart choice. 

When you are investing in solar equipment that is practically going to stay with you for a lifetime, you would want to know the key facts to make the right choices for your home and family. If you partner with an experienced solar installer in Delhi, they will be able to guide you at every step of your solar transition journey. The main thing to focus on is getting the right system for your situation.

  • How much does an off-grid solar system cost? Apparently, a dime! It costs the highest amongst all types of solar systems since they require batteries. However, don’t let the initial investment scare you. Instead, learn all about the benefits that outweigh the cost.
  • Unlike an on-grid system, you go for a much higher capacity model when investing in off-grid solar. Your stand-alone system must be able to generate enough energy to power your home but also maintain ample surplus for storage to use during zero energy production hours.
  • The extra energy that your system produces during the daytime is not sent to the government grid but is stored in batteries to be accessed during rainy or cloudy days, at night, and in the winter weather.

Subsidy on Off-Grid Solar System

There’s no subsidy applicable to purchasing an off-grid solar system for your home. You can only avail government subsidies if you are purchasing a grid-connected solar plant.

The government of India is pushing residential rooftop solar installations by offering subsidies on the solar system’s benchmark cost. A 40% subsidy is available on a solar unit of 1 kW to 3 kW capacity, whereas the subsidy is 20% for units of higher capacity (up to 10 kW).

However, it is important to learn about what all types of solar systems are and which systems are eligible for government subsidy. The three types of solar power systems in India are:

Although you would want to select your solar system that best meets your home’s electricity needs, the solar subsidy is also a major consideration for individuals planning to buy solar. So far, the subsidies are available on grid-connected units and hybrid solar systems (the cost of batteries will not be included in calculating the system’s total cost).

As per the latest updates from MNRE, there is no provision for subsidies for off-grid or stand-alone solar systems.

FAQs About Off-Grid Systems

Do solar inverters work at night?

No. The solar inverter’s job is to convert DC energy coming from solar panels into AC energy. When solar panels are not capable of generating electricity due to weak solar radiation, the inverter in your off-grid solar system turns off during this period.

Does the power outage affect the off-grid solar system?

Not at all. An off-grid solar structure isn’t connected to the government grid. So any power failure related to the grid will not influence the working of your inverter or any part of your off-grid solar system for your home.

Which solar system is suitable for me: on-grid or off-grid?

There are both advantages and disadvantages to using on-grid and off-grid solar power systems, and making the best choice varies from one home to another. You might think an on-grid system is suitable for your home until you recall all those days when outages disrupted your routine. Or you might lean towards off-grid as you would rather choose to disconnect from the grid. If you are not convinced about either of them, you can customise a hybrid solar system to work specifically for your situation.

How do I determine if my home gets enough sunlight for solar panels to work?

Off-grid solar systems for homes require an uninterrupted supply of sunlight to generate enough power for your daily needs. However, it does not mean high temperatures during peak summer days. Solar panels absorb sunlight (not heat) to create energy and, thus, work more efficiently in clear skies. Your solar installer is likely to be familiar with standard calculations to help you with the sizing of the solar system and estimating ROI and savings.

What is the main difference between living off-grid and on-grid?

If you have a professionally designed and installed solar system, there is little difference in living with either type of solar structure. Both the systems ensure that you have the power needed in your home. In an on-grid system, you depend on the grid for additional electricity, whereas you use electricity stored in the batteries in an off-grid system.

Do I get warranties to cover my off-grid solar power system?

Yes. Most solar companies in India are able to provide 25 years of performance warranty on solar panels. Other components, such as inverters and batteries, are also covered by a limited warranty of 5-10 years, depending on the brand. This means that you are protected against unexpected failures and performance issues if any occur in your system.

Is solar maintenance costly and time-consuming?

No. The modern solar equipment is highly efficient and robust to provide users with years of hassle-free, low-cost solar energy. With routine cleaning of solar panels and period maintenance of all solar components, you can keep your off-grid solar system for home working at its peak efficiency level. Moreover, several installers top your solar system with the convenience and protection of AMC maintenance packages. This ongoing solar service plan ensures that your system’s service needs are always fulfilled on time.

Types of 1kW Home Solar System

To cater to the varying electricity needs of customers, there are three different types of solar systems available in India.

  • On-grid 1kW Solar System (with grid export)
  • Off-grid 1kW Solar System (with Battery Backup)
  • Hybrid 1kW Solar System (Solar Battery Storage with Grid Connection)

On-grid 1kW Solar System

Also known as a grid-tied system, an on-grid solar system allows you to draw electricity from both your solar system and the grid. It consists of only two main components — solar panels and a solar inverter. Since the system does not have a device like a solar battery to store the electricity, it does not provide power backup. The electricity is generated from solar panels and passes through the inverter, where it is converted from DC to AC for household use. 

If electricity generated is more than your consumption, then excess power will be automatically exported to the utility grid. In this way, you can export extra or unconsumed electricity to the grid and gets compensated for it with days when your consumption exceeds generation. On average, a 1kW on-grid solar system produces about 4-6 units per day depending on your location.

on-grid solar system

Here are some key highlights of having on-grid 1 kilowatt solar panels at home:

  • Since this type of solar system requires fewer components, it is on the affordable side — no recurring costs.
  • Electricity is consumed as per the home power requirements.
  • Extra power generated is exported back to the grid. Net metering ensures and keep a record of all units exchanged between you and the grid, which reflects periodically in monthly bills.
  • The utility grid can be used to draw power in case of less energy generation from the solar system and at time when there is no generation, like night.

Off-grid 1kW Solar System

Also known as a solar system with battery backup, off-grid solar systems are designed for places with no access to grid or when the homeowner wants independence from power outages. This kind of solar system comes with solar batteries and can function effectively independent of the grid connection. The main components include solar PV modules, solar inverter, solar battery (solar battery, normal battery, or lithium ion battery), and the balancing equipment (mounting structure, mc4 connectors, DC wire, DCDB box, and earthing kit). 

With this system, the unconsumed electricity does not go back to the grid. Instead, it gets stored in solar batteries. It is a complete power bank in itself and provides a power backup when your solar panels aren’t producing electricity. On average, a 1kW off-grid solar system generates 4-6 units per day.

off-grid solar system

Here are some key highlights of having off-grid 1 kilowatt solar panels at home:

  • Works without a grid; battery is used as the device to store power, and it acts as a grid in itself
  • When the solar system does not generate electricity due to a lack of sunlight, the system utilises the stored power to run electrical appliances.
  • Ensures reliable power supply

Millions of homes in both urban and rural India have idle rooftops that receive plenty of sunlight during the day. These are ideal for capturing the sun’s energy and converting it into electricity. Why keep rooftop idle when you can generate your own power/ energy from the roof.

This article is curated to act as a go-to guide for solar plant prospects who need to know everything related to rooftop solar panel systems in India. Read on to get answers to questions like what rooftop solar systems are, how much solar roof panels cost and more.

What is A Solar Rooftop System? 

Solar rooftop panels as part of solar power systems are installed on the roofs of commercial, industrial and residential buildings. They capture the energy from sunlight and convert it into usable electrical energy. This helps in generating a clean, environmentally-friendly form of energy, emitting no pollution or harmful gases.

Read About: 1kW Solar System Price in India with Subsidy

Contrary to popular belief, harnessing the sun’s power isn’t very complex, and anyone with an idel rooftop can generate their own solar power. Using rooftop solar at homes can help homeowners harness electricity from the sunlight and convert it into electricity for their daily household needs. When photons–lightning energy–hit the rooftop solar panel, the photons are converted to electrons of direct current (DC) electricity. Electricity safety devices can be supplied with direct current electricity. Rooftop solar panels are also equipped with inverters, which convert direct current electricity into alternating current (AC), used by various devices and home appliances such as computers, televisions, and even washing machines.

How does Rooftop Solar Panels for Home work?

Rooftop solar panels rely on inbuilt solar cells to harness solar energy and convert it to electricity. It’s a small, square-shaped semiconductor made of conductive materials like silicon. When sunlight strikes solar cells on a solar panel, it causes a chemical reaction that releases electrons, resulting in the generation of electric current in the form of DC. The majority of rooftop solar panel cells are photovoltaic cells, also found in small appliances such as calculators.

A photovoltaic (PV) cell, or solar cell, is the main functional part of any rooftop solar panel. Photovoltaic cells are of three types:

Photovoltaic cells are of three typesSingle-crystal cells: These solar cells are made in the form of long cylinders that are cut into hexagonal or round wafers. This type of solar cell operates at higher power, making them more expensive than other types of photovoltaic cells. Installing single-crystal cell modules can increase the efficiency of your home by up to 30%. This type of solar panel accounts for almost 29% of the global solar panel market.

Polycrystalline cells: These PV cells are made from molten silicon ingots that are then sliced into small squares. The cost of roof solar panel manufacturing having this type of cell is lower, but its efficiency is up to 15% lower than that of single-crystal cells. Because the squares are small, they can be easily packed closely together to increase energy production.

Amorphous silicon: With this type of solar cell, silicon is sprayed in thin films on the glass or metal surface, making the production of such solar cells the least expensive of the three. However, it results in very low efficiency of about 5%.

What are the Main Components of a Rooftop Solar System?

A complete solar panel system, also known as a solar energy system, is made up of four key components:

Components of a Rooftop Solar System

  • Solar panel: A board-like structure with grids that is commonly seen on rooftops. It is the most important component responsible for converting solar energy into electricity.
  • Solar inverter: An electrical device that converts the solar panel’s direct current (DC) to alternating current (AC).
  • Solar battery: It stores the energy generated by the sun and uses it when the grid turns off.
  • Module mounting stand: It is a simple metal structure usually made of galvanised iron. It secures the panels at a specific angle and keeps them from being blown away by the wind.

Apart from the above components, a typical solar panel installation process also requires the following accessories:

  • DC wire: A PVC coated wire in two configurations: less than 3kW and a cable tray of 3kW and over.
  • AC wire: This connects the inverter to the grid and the home power load.
  • DCDB: It protects the panels from the DC side. It is a small solar protection device that is installed between a solar panel and a solar inverter. 
  • ACDB: It handles the alternating current. It is a small solar device that is installed between the solar inverter and your home load.
  • MC4 connectors: single-contact electrical connectors commonly used for connecting solar panels with each other.
  • Lightning Arrester (LA): This device protects solar panels and connected appliances from sudden power surges due to lightning strikes. It is compatible with both off-grid and grid-tied solar inverters.
  • Earthing kit: 1 to 3 kW: It is done via two earthing. The first is for the inverter, and the second is for the LA(Local Earth). Over 3kW: It is held together by three earthing rods. The extra one here is for PV modules.

Benefits of Rooftop Solar Panels

Besides the fact that large-scale installations account for nearly 87 per cent of solar power generation in India, the adoption of solar rooftop panels by households is also rising. Between 2013 and 2022, the installed capacity of the solar rooftop increased from 117 MW to 6645 MW as of Mar 2022. Taking this enormous growth into account, the Ministry of New and Renewable Energy (MNRE), has set a target of 40 GW of rooftop solar power by 2022 through its National Solar Mission of India. There are several reasons why the Indian government is adamant about upscaling solar panel installation throughout the country.

Benefits of Rooftop Solar Panels

Following are some of the benefits of solar rooftop system:

  • Cost savings:

The most significant advantage of installing a rooftop solar panel for home is the cost savings. Rooftop solar tariff rates are 17 per cent and 27 per cent lower than industrial and commercial tariff rates, respectively. Rooftop solar installations are also achieving grid parity in many Indian residential sectors. Rooftop solar installations can even help building owners save money on their electricity bills. Rooftop panels provide electricity to buildings, allowing them to purchase less electricity from the grid and save money on energy costs.

  • Secure investment:

Electricity prices are known to fluctuate from time to time. As a result, calculating the cost of electricity for a given period is difficult. When it comes to electricity that is generated by solar rooftops, however, the price of power generated can be easily calculated. One can even calculate the cost of generating electricity for the next ten years. In this sense, it is a safe investment.

  • Increases access to energy:

Despite the fact that India’s power shortage is rapidly shrinking, many people in rural and urban areas continue to have an insufficient and unreliable supply of electricity. These people must rely on alternatives such as diesel generators. These alternatives are hazardous to one’s health and environment, and their operating costs are also high. In such cases, solar energy serves as a cost-effective, reliable source of electricity. Rooftop solar panels are environmentally friendly because they use the sun’s energy to generate electricity. Furthermore, their operating costs are consistent.

  • Reduces carbon footprints:

Solar panels generate electricity from sunlight, which reduces carbon footprints. As a result, they pose fewer environmental pollution risks than traditional energy sources. They run silently and emit fewer harmful gases than generators. It is also an effective source of energy generation in the fight against climate change. As a result, rooftop solar is ideal for lowering carbon footprints.

  • Low maintenance cost:

The fact that rooftop solar panels require very little maintenance is a major factor that emphasises their importance. They have a service life of more than 20 years if properly maintained.

Types of Rooftop Solar Systems 

Rooftop solar PV systems are classified into three types:

  1. Grid-tied: These rooftop solar systems are primarily intended to feed generated power back into the grid while you withdraw power as per your domestic consumption from the grid. During a power outage, the inverter shuts down the system, preventing power from being sent into the grid and avoiding the risk of electrocuting utility workers who are working to repair the grid.
  2. Grid-interactive: This system works with either a battery backup or a diesel generator to support the load even when the power goes out.
  3. Off-grid: As the name suggests, this solar power system is not made to work with the grid, rather, it is designed to work only with a battery backup or diesel generator in off-grid applications.

How to choose the Best Rooftop Solar System

How do you pick the best rooftop solar system for your home? Consider the following factors to make the best decision:

Certifications: Just as you would not buy an uncertified or untested electronic device for your home, make sure you follow the same logic when selecting a solar panel. Choose a product that is BIS or Bureau of Indian Standards (formerly ISI or Indian Standards Institution) certified. Installing rooftop solar systems for your home is a significant investment that will last for a long time, so make sure you go with a reputable brand.

Inverter efficiency: A power inverter converts the direct current (DC) current generated by solar panels to alternating current (AC) current, used to power your home. The greater the inverter efficiency, the greater the power output and savings. Consider the inverter efficiency of the solar panels you’re thinking about buying, as this directly impacts how quickly the system will become profitable for you.

Type of panels: To choose the right type of solar panels, consider the space available on your rooftop. There are currently two types available: monocrystalline and polycrystalline. Monocrystalline panels are more efficient and take up less space, but they are also more expensive. Still, both are distinct, and the best option will depend on the amount of space you have available and your budget. Make sure you ask about both before deciding on one for your home.

Cost: When it comes to solar panels, cheap is not always the best option. If you notice a significant price difference, look into other factors such as warranty periods, installation, and equipment quality. Inferior quality components may save you money in the short term, but their cost will add up and affect efficiency and reliability in the long term.

Subsidy For Rooftop Solar System

To encourage the use of solar energy, the Indian government provides subsidies to those who install rooftop solar panels in-home or commercial properties. According to the Ministry of New and Renewable Energy, the government pays the installer 30% of the installation cost as a subsidy.

The Indian government is aiming for a total capacity of 40 GW from rooftop solar (RTS) projects by 2022, 4 GW by grid-tied rooftop solar systems. The solar subsidy adds significantly to the long list of their green energy option benefits. If you’ve been hesitant to go solar because of the high initial investment, the prices of solar power systems for homes in India after subsidy are worth considering.

To put things into perspective, suppose your solar vendor recommends a grid-connected unit with a capacity of up to 3 kWp for your energy needs. Then in that particular scenario, based on the benchmark cost of your home’s first solar plant, you will be eligible for a 40% subsidy (also known as Central Financial Assistance). Moreover, there is a 20% subsidy for units larger than 3 kWp and up to 10 kWp. However, the benchmark cost varies by state, and the subsidy rates also fluctuate based on the state’s solar policy. As a result, it’s critical to work with an experienced solar company to ensure that you take advantage of government-provided financial assistance and lower the total cost of solar panels for your home.

FAQs

We hope that the above sections of this article helped you in understanding how rooftop solar panels work and what benefits you will get from having a solar rooftop system in your house. Following are answers to some other popular queries that people have when they dwell deeper into considering a rooftop solar panel for their home:

How much does rooftop solar cost in India?

A 1 kW rooftop solar system costs between Rs 55,000 to Rs 85,000, excluding batteries. This is starting range for a simple rooftop solar system that will cover up your terrace. The more customizations you ask, the more dear it will become. Subsidy is 40% of benchmark cost for 1-3 KW system and 20% for every KW of solar system till 10 KW. We will assume that the rooftop solar systems are connected to the grid and that the energy is not stored in batteries.

Is rooftop solar worth the cost in India?

When compared to traditional methods of producing electricity, solar panels have a significant advantage. They have the potential to provide a long-term sustainable energy solution for many of our daily needs. Rooftop solar panels, according to studies, reduce greenhouse gas emissions as well while lowering electricity costs for you.

What is a rooftop solar subsidy scheme?

Under this scheme, the Ministry of New & Renewable Energy (MNRE) will provide a 40% subsidy for the first 3 kW of solar panel capacity and a 20% subsidy for capacity above 3 kW and up to 10 kW of solar panel capacity. The residential consumer must pay the cost of the rooftop solar plant by reducing the Ministry’s subsidy amount given to the solar energy company at the prescribed rate.

Is 1 kW enough to run a house?

According to solar power system experts, one kilowatt (kw) of the solar system is sufficient for an average family of three to four people with only requirement of running a couple of tubelights, charger and fans. However, for a larger family or to run an air conditioner at home, a 3-5 kW solar system will be required at least.

Can we run AC on a solar panel?

Air conditioners can be run on both on-grid and off-grid solar systems. The only difference is that in off-grid systems, you can run your appliances even when there is no electricity, whereas, in on-grid systems, this is not possible.

What is the maintenance cost of roof solar panels in India?

The maintenance cost of a solar power system depends on the type of roof solar panel you opt for. Suppose you plan to install a solar on-grid system. In that case, the maintenance cost is negligible because it is a battery-free system, and all other components such as solar panels, solar inverters, distribution boxes, AC, and DC cable can easily last 15 – 20 years with little maintenance.

Why are solar panels not popular?

There is still very less awareness about the many benefits of rooftop solar power for homes. Not many people know that the prices have come down to a level where it is not very easy to install a rooftop solar system for your house. In addition to solar subsidy, which have made solar rooftop even more affordable for homeowners. 

Is rooftop solar viable for Indian homes?

India is in an ideal geographical location, so it receives plenty of sunlight (almost 300 sunny days with clear skies each year in India). As a result, rooftop solar systems are ideal for use in India because they convert sunlight into electricity.

Is there any subsidy on solar panels in India?

Yes, the Indian government offers tax benefits to people who install rooftop solar panels for  commercial & industrial use. According to the Ministry of New and Renewable Energy, the government pays the residential solar customers a subsidy of 40% of the installation cost.

How much does a 5kW solar system cost in India?

A 5KW rooftop solar system can cost anywhere between Rs 2,65,000 to Rs 4,25,000 for a roof mounted solar rooftop system. If you are looking to continue using your rooftop even after you install a rooftop solar system, you should be ready to shell out some extra money as the solar energy company will provide a heighted system to install your solar panels at a min. height of 2.2 metres from the terrace.

Solar is a popular alternative power source, and home solar power systems have come a long way in terms of energy generation efficiency and reduced initial investment to make solar cost-effective and rewarding for individual homeowners.

The various components that make up a residential solar plant include solar photovoltaic panels (PV modules), inverter, batteries (in case of off-grid solar solution), module mounting structure (MMS) , bi-directional meter, and tools for the balance of the system. Constant improvements in solar technology have made solar components highly versatile, durable, and suitable for nearly any climate and property type.

Benefits of Solar System for Home

Solar electricity powering our homes is the future! Solar is advantageous not only for our pockets but also for the climate. Energy savings is the biggest motivator for homeowners to opt for this green energy technology. 

Saves money – Solar helps you save substantial amount of money in annual electricity costs and can pay back your initial investment in just 6-8 years. Eventually, you not only recover your initial solar plant cost for your home but continue to produce your own low-cost domestic electricity that increases the return on your solar investment during its lifespan.

Adds value to the home – Solar is an attractive upgrade to your home and an amazing selling point if you decide to market the property in future. A property installed with solar plant  also impact buyers’ property purchase decisions as the buyer would want to purchase a house with in-built operational solar plant for home. A solar powered home producing cost-effective  electricity for years will attract more potential buyers.

Freedom from the grid – Using a solar system for your home in India can give you independence from the  grid. You can choose to completely go off the grid or reduce your dependence on it by producing your own domestic electricity through a home solar power system with battery storage technology. It will keep your home powered even during unannounced power cuts.

Cost-effective – Owning and maintaining a solar plant in your home is hassle-free. Solar systems of present times are highly durable and weather-resistant, with a lifespan of over 30  years. With regular  cleaning and minimal maintenance, your solar panels ensure years of efficient electricity production for all your domestic needs.

Environment friendly: The traditional process of generating electricity using coal as a fuel releases tons of toxic gases into the environment and causes air pollution. Using renewable energy sources like solar is definitely the best way to cut down on emissions and save the environment. 

How a Solar Setup for Home Works

Simply put, solar PV systems are advanced power generation stations that have solar panels to absorb sunlight and convert it into electricity and other components to give you the usable supply to power your appliances.

How a Solar Setup for Home WorksSolar systems work  on the principle of the photoelectric effect. Solar panels are the main workhorses in a home solar setup and work to generate electricity. Each solar panel is composed of a collection of solar PV cells that efficiently capture sunlight. Each PV cell is made up of semiconducting material. As light falls upon this material, it sets electrons in motion that cause the electric current to flow within the material – called the photoelectric effect. The wiring among solar cells across the solar arrays on your roof captures this electric current and results in the generation of DC electricity.

Since your home appliances and electronics don’t work on DC current, the energy passes through a solar inverter to get converted into AC current before subsequently consumed in the house, transferred to the grid, or stored in solar batteries for backup electricity. 

How to Choose the Best Solar System for Your Home?

Your reasons for considering a home solar power system will dictate what type of system will work best for you. Evaluating each type of solar system in connection with your yearly power consumption and the solar plant cost for your home will help you make a confident decision.

Suppose your monthly electricity bill is your biggest pain point, and you are considering solar to bring down the overall energy cost. In that case, a grid-connected home solar system will help you reduce your dependence on the grid. At the same time, you can enjoy net metering benefits (more on this in the FAQs). 

An off-grid solar system is an independent power bank for homes and can be set up  anywhere where the grid hasn’t reached. Batteries are essential to maintaining the availability of surplus power at all times of the day. For this reason, your solar installer will recommend a higher capacity unit to generate ample power all year round. 

Types of Home Solar Systems

Finding the best solar system for your home in India requires you to make an informed choice among the different types of residential solar PV plants. On-Grid, Off-Grid, and Hybrid are the three main types, and each comes with its own set of pros and cons.

On-Grid Home Solar System

This is the most popular solar system for houses that are already getting regular power supply from the local grid. Upgrading to a grid-connected solar plant  allows you to draw energy from your solar plant as well as the grid as you’re connected to both through the net metering system. The two main components in a grid-connected solar system are solar PV module  and a solar inverter. Although this solar setup for homes is  cost-effective, a drawback is that you don’t have  solar batteries to keep you running during power outages..

Off-Grid Home Solar System

An off-grid is the best solar system for homes located in remote locations away from the grid. You achieve absolute energy independence by empowering your home with its own solar power bank. Off-grid or stand-alone systems work independently, without any intervention from the government grid. Since you entirely depend on your solar system for power in all seasons, one or more solar batteries are included in your setup, increasing the total solar plant cost for homes to ensure that you always have surplus energy to use on low–production days and at nights.

Hybrid Home Solar System

As the name suggests, a hybrid solar structure is a combination of both on-grid and off-grid units – meaning it is connected to the government grid and has a battery backup too. Homeowners who don’t want to depend on electricity providers and don’t want to be affected by power cuts go for hybrid systems. Since it has the most number of components, including devices for net metering, battery backup, cables, and more, they cost the highest among all types of home solar systems. 

Reasons to Get a Solar System for Home

There are endless reasons that make solar an advantageous option for homes. Among all the renewable energy sources, solar promises long-term financial and environmental advantages for homeowners.

  • Solar power is a free, sustainable energy source.

The conventional energy sources are strained as we try to meet the rising energy demand. However, solar is a more economical, environmentally friendly, and financially beneficial alternative. Its complete advantages unfold in the long term, where homeowners get a reliable 24/7 electricity supply, reduced utility cost, and zero carbon emissions. 

  • Solar can eliminate grid dependence.

Many remote locations don’t have access to the government electricity grid. By investing in a home solar system kit in India, you can achieve energy independence and get low-cost solar electricity. You can further ensure electricity is available during the night hours and on rainy days by getting solar battery storage systems.

  • Solar power reduces electricity loss.

Not many know that valuable units are lost during electricity transmission from big power plants via extensive networks to the end customers. With a rooftop solar setup for your home, your electricity becomes domestic as the power-generating panels are positioned right above your home, meaning almost no  energy units loss and a short transmission distance.

  • Solar power increases grid security.

As more and more homes transition to solar power, blackouts or brownouts will be few.. Opting for battery backup will enable you to remain unaffected by blackouts in the case of a grid-connected solar system for your home in India.

How to Set up Home Solar System

When planning to switch to renewable energy sources, you must abide by some key steps to get the maximum benefit of solar systems for home electricity. 

  • Analyse your home’s energy efficiency

A complete energy audit of your home by a trusted electrician will help you determine the different uses of electricity in your home and if you are losing valuable units in the process. Also, investigate what all appliances and lighting systems you use are of old, low-efficiency models and consider replacing them.

  • Find out your home’s solar potential

Although modern solar technology effectively captures both direct and scattered sunlight to produce energy, some homes might not have enough solar potential to make the investment worthwhile. Check if your roof gets enough sunshine during the day, as well as nearby trees and plants that might cast shade on your solar panels. 

Homes built a long time ago can have compromised roofs that need to be replaced immediately or in a couple of years. Also, if the local homeowners association regulates your home, make sure you check with them about the suitability of getting a personal solar system for your home.

  • Options for using Solar

When you’re ready to power your home with solar, purchasing your own home solar system isn’t the only option available. Multiple solar programs are on offer to make the solar transition comfortable and smooth, even if you rent a home or don’t want to invest a large amount in installation. 

If you are part of a community, the households together can opt for a shared solar set for homes. Solar leases are also available for individuals who can’t afford the system but would prefer leasing one. Alternatively, you can enter into a power purchase agreement – a third party agreement wherein the ownership lies with a third party who puts the solar equipment on your rooftop for a monthly rent.

Solar Plant Cost for Homes in India

Wonder how much the solar system costs? Here are figures of what the market costs look like for different solar systems for homes. Ranging from 1kWp capacity to up to 10 kWp for residential use, factors like the size of your property and its energy consumption needs will decide the right home solar power system and the components it will have to suit you and your family.

  • Solar brand, location, promotions, and availability directly impact the solar plant prices for homes. 
  • Also, note that the above prices are exclusive of state and national government subsidy schemes and other financial assistance programs.

Home Solar Subsidy in India

The government of India is chasing a target of a cumulative capacity of 4 GW from rooftop solar (RTS) projects by 2022. Solar subsidy adds greatly to the long list of advantages of their green energy alternative. If you have been on the fence about solar due to its overwhelming initial investment, the solar system for home prices in India after subsidy is worth considering. 

The new simplified rooftop scheme by MNRE gives individual solar buyers the liberty to choose from rooftop solar companies in India to get solar plants for homes. The homeowner will have to notify the local DISCOM and submit an application for the intended Rooftop Solar installation to initiate the subsidy reimbursement process.

Suppose your solar vendor suggests you go for a grid-connected solar plant of up to 3 kWp capacity for your energy needs. In that case, you will be eligible for a 40% subsidy (also called Central Financial Assistance) on the benchmark cost of the solar plant for your home. There is a 20% subsidy for units above 3 kWp and up to 10 kWp. However, the benchmark cost varies across states and so does the subsidy rate according to the state solar policy. Hence, it’s important to connect with an experienced solar company that can ensure that you take advantage of government-provided financial assistance and reduce the total price of solar power for your home.

FAQs – Your Common Questions Answered

How do I figure out the amount of solar energy I’ll need?

Your home solar system in India should generate ample electricity to fulfil your average annual electricity consumption. Review your electricity bills for at least the past 1 year to figure out your electricity needs. You can even ask your solar vendor for guidance or, better yet, an estimate.

What is net metering in an on-grid solar system for the home?

Since solar panels only generate power during the sunshine hours, a net-metered solar plant for the home allows you to draw power from the grid when solar power generation is not sufficient on any day. Conversely, unused units are transferred to the grid for solar credits on excess solar production days. The net meter records both the direction of energy flow when sending you the final monthly bill.

What if my roof doesn’t get enough sun?

Solar systems for some houses may be unfavourable if the roof doesn’t get enough sunshine due to major constraints like shade cast by the neighbour’s property or unfavourable facing of the roof. A solar installer can better evaluate your roof’s solar potential or might suggest you join a community solar farm that offers the advantages of solar without installing panels on your roof.

How long is the payback time on the best solar systems for homes in India?

The standard payback period is 6-8 years for solar-powered households. However, factors like the cost of grid electricity for your area, the cost of your solar system, method of payment (if you took a loan or lease), and your electricity consumption needs can influence your payback time. Regardless of it all, the 25 years of reliable, cheap, and significant energy output make solar advantageous for the most.

How long will my solar panels last?

Many solar companies will cover your home solar power system with a 25 years performance warranty. Although their energy output efficiency might start to decline after the initial years, they will still give 85% of their original production quantity throughout its lifespan of 25 years, after which the output will decline, but the panels will still generate some electricity.

Are components in the solar system for home electricity backed by warranties?

The standard warranty for solar panels is 25 years. However, the other components like the inverter and batteries are also backed by significant product warranties that vary across brands. Your installer will also provide a workmanship warranty on the solar installation work.

Is solar maintenance costly?

Keeping your solar setup for your home up and running requires periodic cleaning and maintenance. However, major failures in rooftop solar structures are unlikely as solar panels don’t have any moving parts. Also, your solar provider will cover your routine service needs with an AMC package. This maintenance package includes periodic inspections and other comprehensive services that help prevent downtime, maximise the system’s performance, and extend the life of your home solar plant.

Take a Step Towards a Better Future with Home Solar

No Comments

The government of India is promoting solar power as a cornerstone source of energy in the renewable energy mix on a massive scale. Favourable policies, solar subsidies and tax benefits (accelerated depreciation) have amplified the advantages of solar for domestic solar manufacturers, solar panel installers and end consumers of solar. Let’s dive deeper into each aspect and discover how solar is a great investment. 

Long-term Benefits for You and the Environment

The answer to whether or not solar is the right decision for you can be found in the long-term advantages of solar. And in all these cases, it seems “Going solar” is indeed a smart way forward. Solar electricity is good for the environment primarily because solar power generation doesn’t emit very high carbon emissions, thus helps fight climate change and our dependence on non-renewable energy sources, like coal. 

Most solar installation companies in Gurgaon, Delhi and other parts of India offer higher efficiency solar systems that help homeowners produce power for themselves and make them energy independent and take less or no energy from the local grid. As a result, you reduce  or eliminate your energy cost and maximise savings in the long run, especially considering the government subsidies for home solar. Another great advantage with solar PV systems is that they are easy to maintain and come with manufacturer’s warranties, thus becoming a great value addition for homes.

United Steps Towards a Better Future

From the time India committed to take stronger climate change mitigation measures under the Paris Agreement, the government has introduced several tools and policies to encourage the quicker adoption of solar. The endeavour is to create a clean energy future where the citizens can reap numerous environmental and economic benefits of solar systems.

The Union Budget 2022-23’s announcements objectively factor in the emerging requirements of India’s renewable energy sector and aim to help it become more self-reliant and competitive. By further increasing funding in the Production Linked Incentive (PLI) program, the government intends to enable domestic solar manufacturing through fully-integrated units. This will end India’s reliance on solar imports and can even make India a key solar exporter. 

The imposition of Basic Customs Duty from April 1st, 2022, is going to be another gamechanger in the country’s efforts to strengthen domestic solar manufacturing. Though, in the short term it will make solar a bit expensive, but when domestic solar manufacturing hits economies of scale, it will be beneficial in the long run. By levying a high import duty of 40% on solar modules and 25% on solar cells, the domestic solar industry will be safeguarded against the cost competition from the solar imports and have a supportive ecosystem to grow. It’s expected that the cumulative effect of these efforts will also bring down the cost of solar systems for the end-users in India in the long run.

Adopting rooftop solar for homes is easier and more accessible with the simplified rooftop solar scheme by MNRE. Homeowners will now have the freedom to select solar equipment and to have solar power companies of their choice do the installation. Also, applying for solar subsidies is much simpler with the new online process upon which the consumer directly receives the subsidy payout in 30 days in his/ her account.

You can do your part in building a green future for India by installing your own home solar power plant in Gurgaon or anywhere in India.

How to Plan Solar Panel Installation for your Home

No Comments

Getting  rooftop solar system for your home is a smart investment to get practically free power for the system’s complete lifecycle of  more than 25 years. However, there are several steps to ensuring a successful solar installation, and it starts with obtaining a broad overview of how this green energy system will work for you. 

An initial site visit and technical assessment by an experienced solar company will be done where your annual electricity consumption will be assessed and location suitable for installing solar panels will be analysed for any shade. The technician will also help you consider solar system capacity, its estimated cost, and the possibility of net metering. You will also learn about the projected solar energy generation and the savings or return on investment you can expect after getting home solar plant.. 

The energy generation of your home solar panels largely depends on how the solar panels are installed on your rooftop.

Here is a step-by-step guide to getting solar panel installation done right.

Location of the Solar Panel (Roof or Ground)

When it comes to onsite solar installations, rooftop solar is preferred for a flat roof as installing solar is fast, easy, and convenient. Another unheard advantage of a solar structure designed for a rooftop is that the solar arrays keep your building cool in the summer by providing a physical cover against scorching heat. Solar panels can also work efficiently on slanted roofs. The decision depends on whether your roof’s size and strength is suitable to accommodate the installation. Also, check if your roof is free of shade from nearby trees and structures. 

You can consider ground-mount installation for your solar panels if your roof can’t accommodate solar and you have ample space for the installation. However, to ensure the suitability of your ground location, check if the area is:

  • Free from obstructions and shadows cast by nearby trees and structures.
  • Flat as steep terrain can lead to costly installation.
  • Dry with good drainage to prevent standing water.

A residential solar system is usually installed inside the property. However, solar panel installations can also be done at distant locations for a group of consumers and they can in turn draw power as per their usage, this concept popular in the west is known as community solar. Parking lots are ideal for ground mount solar plants, which upgrade them into solar energy-generating assets and keep the vehicles protected in warmer months.

The Right Direction for Solar Panel

For countries in the northern hemisphere, like India, true south-facing solar panel placement is recommended to get direct sunlight during the day. It is important to understand that the true or geographic south (direction towards the South Pole) is different from the magnetic south shown by a compass. 

The most optimum direction also depends on how you are installing the solar panels. A home solar panel system, for example, will be more effective if the panels have a slight rotation towards the west, away from true south. The motive for this orientation is to allow rooftop solar panels to produce more electricity in the evening when people are home using the most appliances. This might decrease the total solar energy production but will ensure solar electricity availability when needed the most.

Finding the Right Tilt and Angle

The modern solar panels allow you to adjust the angle and tilt of panels to maximise exposure to direct sunlight and boost sunlight collection efficiency. However, finding the right adjustment setting depends on the geographical latitude. Generally, you can strike an optimal annual solar energy production by setting the solar panel tilt angle the same as the geographical latitude and towards the equator. 

For solar panels located closer to the equator, the panels will be facing upwards. The angle can also negatively affect the production of solar power for your home in an unfavourable climate or environment. Soiling from dust and dirt can happen more frequently on low-tilt solar panels, lowering their ability to collect sunlight.

If you are tired of paying high electricity bills, switching to solar for your home will benefit you immensely. However, getting the most out of your solar power plant in Gurgaon or anywhere in India depends on selecting the right solar options, and a trustworthy and experienced solar installation company makes it all easier for you. 

With HomeScape by Amplus Solar, we go above and beyond to help you make switching to solar a rewarding experience. Our renewable energy solutions for home equip your property with high-efficiency solar panels and easy-to-maintain systems. We make a long-term commitment with our customers and accommodate their service and maintenance needs through a lifetime performance warranty of 25 years and comprehensive AMC packages

Impact Of Basic Customs Duty Hike On Residential Solar

In response to a long-standing demand from India’s solar manufacturing sector, the Ministry of New & Renewable Energy (MNRE) will implement Basic Customs Duty (BCD) w.e.f. April 2022. This move will protect domestic solar manufacturers from the stiff price competition from imported solar modules. Imposing a high tax rate will work in favour of the domestic solar industry in the short term as the price gap between imported solar components and locally-produced solar components will be be bridged.

However, this is just one side of how this hike in basic import duty will impact India’s solar sector. The price of home solar systems is expected to rise as material costs across the supply chain become costlier. A home solar system comprises of solar panels, inverter, cables and mounting structure.

Rise in the cost of solar modules is bound to increase the price of a home solar system as module price comprises more than 50% share of the price of the whole solar system. But in order to estimate how much the price is likely to increase, read more. 

Upcoming Changes in Solar Equipment Prices

India is chasing an ambitious goal of 280 GW of installed solar energy capacity by 2030. However, the country has been heavily dependent on imports so far. This has worked against the domestic solar manufacturers as several are on the verge of shutting down. China alone accounts for 80% of the total solar imports, while the rest consists of imports from Malaysia, Thailand, and Vietnam.

The Ministry of New and Renewable Energy recognizes the urgency to protect domestic solar component manufacturers against stiff price competition from imported ones and reduce the dominance of low-cost imports in the Indian solar markets. 

The Basic Customs Duty is a move that will help boost domestic manufacturing of solar components. As per the proposed duty structure, a basic customs duty of 40% on solar modules and 25% on solar cells will come into force on all solar imports starting April 1st, 2022. This tax imposition is expected to be a gamechanger for India’s Atmanirbhar Bharat vision. It will do away with the cost advantage that has allowed imported solar components so far to dominate Indian markets, providing Indian manufacturers a level playing field and the confidence to scale their capacity and performance.

This has come after the BCD for imported solar inverters was raised from 5% to 20% effective from February 2nd, 2021.

Impact of BCD Price Changes on Solar Industry

Long after the expiry of Safeguard Duty in July 2021, BCD is set to take effect from April 1st, 2022, though the intent of this change was already shared by MNRE in early 2021. As a result, the industry will see a slight increase in solar power tariffs being offered to Commercial & Industrial customers due to expensive solar components.

As per ICRA, the capital cost of a solar power plant project will increase by 23-24%. The official notification from MNRE also clarifies that there is no provision for exempting projects already auctioned. This is no brainer that the same price rise will happen for homeowners as well looking to purchase home solar plants for their house. 

Apart from the low cost, the higher efficiency of imported rooftop solar panels is also another major factor why some of the developers and power producers prefer imported solar panels. But this is set to change as domestic solar manufacturers are also working on efficiency and ramping up their production capacities. Also, this hike in solar plant cost is anticipated to be a short-term disruption until local manufacturing achieves economies of scale and becomes even more efficient than the imported solar modules.

To that end, BCD will create a supportive ecosystem for the domestic solar industry by providing relief against the competitive environment created by low-cost foreign imports, especially China. We should also note that import barriers can only be temporary measures. Eventually, domestic solar manufacturing will succeed only if we are able to compete in the global marketplace – in terms of price, technology, and scale.

Why Get Solar for your Home Now ?

The basic customs duty on solar components will be implemented from April 1st, 2022, meaning the current solar prices are still affordable. Hence, if you are planning to solarize your home in the near future, purchases made during this time will still come at old prices. 

Moreover, there is the added benefit of the simplified rooftop solar subsidy scheme recently introduced by MNRE. This updated subsidy scheme allows homeowners to get solar from any developer of their choice and avail subsidy through a simple online application process. The solar subsidy can further bring down the cost of rooftop solar for your home by up to 40%.

How to Prepare Your Rooftop Solar Panel for Winters

No Comments

Your home solar panel system can work efficiently even in cold and harsh winters. All it needs is a little adjustment and maintenance. 

As winter sets in, the days get shorter and sunshine becomes scarce. This change in season also means that it’s time to prepare your rooftop solar system for the chilled and icy weather. Though it is known today that the prevalent solar panels are built to withstand all elements of weather and don’t suffer damages due to storms, rain, and even snow. With some routine solar panel maintenance, you can expect maximum output during winter season with no unexpected failures. Here’s how you can do it:

Monitor Your Energy Consumption

Although the amount of sunlight your home solar panel system gets is reduced during winter, it is still more than enough in many regions of our country for optimum solar generation. Start conserving energy by cutting down on your home’s excess electricity usage. This may be done in many ways.

Turn off your indoor and outdoor lighting if you don’t need it, and always use energy-efficient lighting fixtures and bulbs. Cover windows and doors with insulated drapes and curtains when using heating devices indoors to reduce heat loss.

Also, check your battery discharge levels as it’s recommended to not exceed the 80% discharge level. You can aim for a 50% level with lead-acid batteries and lithium-ion batteries. For areas experiencing harsher weather, you can even consider getting a backup generator to sustain on days when energy consumption is high.

Look after the Batteries

Deep cycle batteries often accompany your solar panels that require proper upkeep. Use antifreeze distilled water to keep your batteries alive, especially if you’re not connected to the grid, i.e. if you are using off-grid solar solution.

Also, regular battery service by a professional helps you stay ahead of sudden repairs. For lead-acid solar batteries for homes, keep an eye on voltage to ensure that any irregularities get timely attention. Also, periodically check battery temperature, which should be within the recommended range for efficient electricity storage and use.

Solar experts recommend having your solar batteries installed and stored indoors. It’s important not to let harsh weather affect the performance and lifespan of your lead-acid batteries and lithium-ion batteries. When you don’t need batteries in winter, you can disconnect and store your lead-acid batteries at 100% capacity. Keep your lithium-ion battery in a well-insulated area at a 40% discharge level.

Adjust the tilt and angle 

Due to the earth’s rotation and revolution, the sun in winter is at a lower angle. As a result, your solar panels don’t receive as much sunshine as they get in summer. To make the best of what little sunlight you get every day, you can use an adjustable rack to modify the angle of solar panels and tilt them a bit to absorb maximum sunlight during this period.

If this is your first experience of dealing with a residential solar system during winters, it is recommended that you reach out to your solar installer for information on your solar panels’ angular facing during the winter months.

Keep the Solar Panels Clean

Although solar systems don’t need much cleaning effort, it pays to periodically clean your panels during winter. If your region receives snowfall during the cooler months, ensure that you clear the snow covering your panels first thing in the morning so valuable sunlight isn’t lost in melting the snow away. You might also want to clean your panels weekly or fortnightly if your region has high dust and pollution levels. 

Use a soft brush for snowy days and a soft rag/mop on other days. Be careful not to damage your panels, and don’t use abrasive cleaning tools and products. You can again contact your solar installer for a demo of how to clean your solar system on your own without any professional help.

Talk to an Expert when needed

Solar batteries for homes require very little maintenance, which can go a long way towards getting the most value from your solar investment. Your solar company in Gurgaon or Delhi NCR should be able to offer more personalized tips to ensure optimum solar maintenance and performance of your home solar panel system

The best time to have your panel looked at by your solar company is right before winter. There can be debris or hidden anomalies that your solar expert will identify and remedy during a solar inspection. To keep your solar panels and batteries in excellent condition, you should get a routine inspection done at least twice a year.

Are you looking for experienced solar power companies in Delhi, NCR, or Gurgaon to solarize your home?

Personal Guide to install solar at home: Part 5- Rooftop Solar Panel Installation, Warranty and Maintenance

No Comments

In the previous parts of our blog series, we discussed about receiving your solar proposal, documentation and the types of permits. Here is the final part of a five-part ‘Personal Guide to Installing Solar at Home’ series. This article will be covering the installation process, as well as the warranties and maintenance.

Step 9: Installation

Once you’re done with confirming the proposal , site visits, permit work and planning, the actual rooftop solar panel installation will only take a few days of work. If you are installing an on-grid system with net metering, the process will take additional time. While the decision process for rooftop solar panel installation can take a while, the installation time frame is quick and simple. The actual day when your rooftop solar panel installation starts will be exciting.

1) Set-Up

The solar installer you chose will start by preparing your roof and ensuring the shingles or tiles are attached correctly. They will set up a temporary structure used to support the work crew and materials to help in the process. It helps to take care of safety during the whole rooftop solar panel installation process.

2) Solar Panel Mounts

Then, the installer will set up the solar panel mounting system. It will support the base of the solar modules. It’s the only piece of equipment which is attached to your roof. The entire mounting arrangement must have a tilt and have an angle between eighteen to thirty-six degrees to have most sunlight exposure.

3) Solar Panel Installation

After the installer sets up the mounts, the solar module itself has to be installed on the mounting structure. They should make sure to tighten up all the bolts and nuts so that it stays firm and steady. The panels are mounted on the racking when they are firmly connected to the racking.

4) Wiring

Then, they put in electrical wiring that will connect to your electrical panel and the general power system. MC4 connectors are predominantly used as wiring for solar modules. During the wiring installation, the company must ensure that the electricity supply from the grid to home is turned off .

5) Solar Inverter

Once the electrical wiring is done, the installer should link the solar inverter to the system. The inverter(s) are connected to the modules to convert direct current (DC) into alternating current (AC) energy which is used in households and on the grid. The solar inverter may be used indoors or outdoors and is normally placed near the main system.
Inverters stored in a spot that is not too hot are often more efficient. If kept outside, the inverter should be kept out from the afternoon sun. If installed indoors, the garage or utility room is typically the most reliable location as they remain cool for most of the year with ventilation.

6) Solar Battery

If you opt for an off-grid solar system, a battery is necessary since it is used to store backup power ,which is connected with the solar inverter.

7) Grid Connection

To link the inverter to the grid, the installer will have to simply plug it in the main power switchboard, so that it receives power from the grid. The output wire should also be connected with a board that is supplying electricity at home. To determine the excess energy generated from the solar system, the installer needs to install a metering device.
The installation time will range from 1 to 3 days, subject to the size of the system you are installing. Net-metering can add time to your installation process . If your installer needs to add a power meter for net-metering, it might add a few hours to your solar installation.

8) Consumer Unit

The inverter should be linked to the consumer unit (known as the distribution or fuse board) to generate electricity. To observe the amount of electricity the solar modules generate, a generation meter should also be connected . To evaluate your solar systems’ performance, you can check on the HomeScapes’ remote monitoring app.
For instance, you can check the electricity generation data and decide the appropriate time for using your dryer or other utilities. It will also show the import and export of the power happening due to the net-meter.

Step 10: Warranty and Maintenance

Warranty

The final step with significant aspect is the warranty of the solar power system. Warranties for solar panels protect your solar investment and are an integral part of any rooftop solar panel installation. There are two kinds of warranties that keep your modules covered, and knowing the differences between them is vital to make sure you get the most suitable agreement for your solar energy system.
The two types of warranties are:

  1. Product (or materials) warranty
  2. The performance warranty

A product warranty of solar modules covers the panel itself and guards you against obstacles like manufacturing defects, environmental issues and unanticipated wear & tear. A material warranty will typically guarantee 10 to 12 years without the modules failing.
The performance warranty will ensure 90% production at ten years and 80% at twenty-five years. As with most guarantees, more the period, the more it is advantageous to you. The solar inverters come with a 5 year warranty which can be increased by AMC (Annual Maintenance Contract).
Warranties, are a very confusing topic for some solar owners. However, there is nothing to worry as HomeScape provides hassle-free warranty management. We have AMC packages which cover up to the lifetime of the product. You can buy it to safeguard your whole solar system. We present the best-in-class warranty on all parts. In case of failures, you can contact us without having to run to the manufacturer.

Maintenance

As opposed to many other technologies generating power, solar photovoltaic systems have low maintenance and service requirements. However, proper upkeep of a solar plant is necessary to optimize energy yield and maximize the life of the system. Some of the maintenance activities include module cleaning once in 15 days (dust, bird dropping, and other debris can cause a decrease in power generation).

Maintenance activities

The other items to take care of include::
  • Checking module connection integrity
  • Checking junction/string combiner boxes
  • Inspecting mechanical integrity of mounting structures
  • Vegetation control
  • Tightening cable connections that have loosened
  • Replacing blown fuses
  • Repairing equipment damaged during module cleaning or intruders.

Maintenance activities

Homescape Remote Monitoring System:

At HomeScape, we have designed an RMS (Remote Monitoring System) called HomeScape Solar, which is IoT based, to keep a record of the performance of your solar plant. The application can be found in Android and iOS.
It helps with the following functions:

  • Notification alarm– If the plant, inverter or any component is not working properly, the HomeScape Solar app sends you a notification.
  • Various plant parameters – Solar energy generation, solar energy consumption, units fed back to the grid, savings and contribution to the environment can be viewed.
  • Plant performance– The performance of the solar system can be seen at different time scales: daily, monthly, annually or between any pair of dates.
  • String monitoring– You will be able to take a look at all the parts of the system with the help of our app.

In essence, we highlighted how the solar system installation takes place starting from setting up, installing the mounts, solar panels, wiring, inverters, batteries, connection to the grid and consumer unit. We have also discussed about the significance of solar warranties and upkeep. Many of the solar companies, including HomeScape, offer a warranty on solar panels as long as 25 years.
With this article, we conclude our ‘Personal Guide to Installing Solar at Home’ series. It is now time for you to switch to the most eco-friendly option by installing solar systems for rooftops for power generation and use!
Save your money and help the world as well. Be prepared for a world which will soon switch to solar power!
