On-Grid Solar System: A Complete Guide About Price, Benefits, Working and more

May 24, 2022 No Comments

On-grid solar systems are often the first choice for home solar systems as they are flexible and cost-effective. If you are looking for an efficient and green energy source to meet your power needs, consider going solar now. 

With an on-grid system, you have the flexibility to start with a primary energy-generating plant. Then, once you are satisfied with its performance, you can upgrade it. You also can add a battery bank to your solar system setup to tap into the maximum potential of solar technology. 

What Is an On-Grid Solar System?

On-grid refers to a type of solar system that is tied to the local grid. It is highly recommended for domestic use as household energy needs change, usually per diem. The system is designed to manage electricity when energy output exceeds or falls below your requirement. 

On-Grid Solar System

In this system, the grid acts as your battery bank. When the panels get less sunshine and fail to give standard energy output, you can switch to grid electricity instead of buying a battery. In addition, the on-grid system will automatically transfer excess and unused solar electricity to the grid, allowing you to build credit. These solar credits then can be used to purchase grid electricity, or you can cash them out by the end of the year. This arrangement works under the net metering system.

How Does an On-Grid Solar System for Home Work?

Like other types of solar plants, the panel generates electricity in an on-grid solar system. However, since the system is connected to the local grid, the net metering system plays an important role in your monthly electricity cost.

An on-grid solar power system provides your home with the electricity required during sunshine hours. As it is connected to the grid, you can draw power from the battery storage when electricity generation is low — primarily during the night and on cold and cloudy days. The arrangement of solar panels on the roof captures maximum sunlight and converts it into solar power. This energy generated in DC form runs through the inverter to transform into alternating current (AC). This solar electricity is suitable for running your home appliances and all electronic devices. 

When the solar energy generated is more than the requirements of your house, the unused power is fed to the national grid. Similarly, you can draw power from the grid when there is insufficient energy production. The meter box records the import and export of power and eventually tells you the net amount to be paid/received through monthly utility bills.

Components of a Grid-Connected Solar System

The main workhorses in an on-grid solar system for home are the roof-mounted solar panels that convert sunshine into solar energy and the bi-directional inverters that turn DC energy into AC electricity for domestic use. 

The key components that a working on-grid solar system requires are:

PV modules/panels

Solar panels are the key working component of a solar plant. Each solar panel comprises photovoltaic cells (PV cells) placed between semiconducting materials (like silicon). A current field is generated when photons in the sunlight fall on this material – a process called the photoelectric effect. This results in the generation of direct current or DC electricity.

Bi-directional inverter

The direct current of electricity passes through the inverter and comes out as alternating current (AC). Bi-directional inverters also work to stabilise the output voltage. If you choose to buy a battery bank, this type of inverter will facilitate AC to DC conversion for battery charging.

AC breaker panel with fuses

This type of panel provides a single platform for not only the domestic supply of electricity but also for inverter and filter connections.

Charge controller

It prevents overcharging of the battery and helps prolong the lifespan of your PV system.

Electric meters

The purpose of electric meters is to bill and quantify the energy generated and used. Two meters are required in the working of a PV generator.

Safety switches and cabling

Safety switches (isolation switching and control) are required to disconnect both the AC side and DC side of the bi-directional inverter during testing and maintenance. Also, cabling is used to connect the different solar components together.

Electricity grid

On-grid solar systems are connected to the utility grid for the two-way flow of electricity between the grid and your solar plant under net metering.

Benefits of an On-Grid Solar System

There are plenty of advantages of an on-grid solar system for homeowners beyond the fact that it costs less than other types of solar systems since fewer components are needed. Also, the financial benefits of solar for homes outweigh the cost of PV systems over time, not to mention the incredible environmental benefits solar offers.

  • Constant supply of power

A grid-connected solar system guarantees that your home always gets power, even when your solar system is undergoing repair or generates insufficient power on rainy and cloudy days. You can also opt for a battery bank when personalising your system to store some surplus energy to be used when the grid is down. As a result, you are not entirely dependent on the sun and can draw any additional energy, when needed, from the grid.

  • Energy Cost Savings

With solar powering your home, your monthly energy bill plummets, giving you the joy of small savings. These small portions add up to show significant savings. Additionally, solar investment also promises high returns. Every month you use solar electricity and don’t purchase any grid electricity, your bill will reflect a nominal charge. On days when your panels generate excess electricity, you can export it to the government grid for credit units, which will also reflect in your monthly utility bills. When your electricity exports exceed your imports, you will be paid at tariff rates fixed by the government. Your solar system not only reduces your electricity cost but also becomes a source of your income. These savings accumulate into a large amount over the years, just as enough even offset your initial solar cost in just 6-8 years.

  • Generate your own electricity

When you live in a solar-equipped home, you are nearly grid-independent and can generate the amount of electricity you need to function every day. Your solar company ensures that you get the right capacity of an on-grid solar system based on your electricity needs so that the days when you get to switch to the government grid are as few as possible. Moreover, today’s photovoltaic solar panels are more energy-efficient and give higher energy output against the amount of sunshine captured by each solar cell. As a result, less area and few panels are needed to meet your electricity requirements.

  • Environmentally-friendly

The environmental benefits of solar are a major reason why you should get rooftop solar and why the government is offering subsidies to make on-grid solar power systems more affordable for homes. By adopting solar, you reduce greenhouse gas emissions, lower the demand for fossil fuels, and eventually decrease your own carbon footprint.

On-Grid Solar System Prices in India

Here is a ballpark estimate of on-grid solar system prices in India. However, figuring out the exact cost for your household will require factoring in subsidy, the size and type of your system, and your location. Again, an experienced solar company will be able to help you. 

Most homeowners prefer on-grid systems as they offer flexibility and a high return on investment through net metering. Although multiple variables influence the final cost of solar for a household, a standard system ranges from Rs. Rs. 66,999 for a 1kW model to over Rs. 4 lakh for a 10 kW model.

Please note that: 

  • The on-grid solar system prices mentioned above are ballpark figures as per watt cost might vary due to location, availability, promotions, and solar brand.
  • The prices are exclusive of subsidies being offered. The subsidy is based on the buyer’s eligibility and the type of solar system setup.
  • Homescape can provide you with a more accurate estimate on your right-fit on-grid solar system in UP or anywhere in India.

Installation Cost of On-Grid Solar Systems In India

Typically, the total cost of your on-grid solar system is inclusive of the installation charges, which depend on factors like the number of panels in your solar plant and the complexity of the installation.

If you select an experienced solar company in India that provides one-stop solar solutions, their offerings are inclusive of all costs. Your solar provider will create a customised design for the on-grid solar system for your home, and the system will be topped with warranties and AMC maintenance packages. You will also receive an efficient installation service and a streamlined process for the commissioning of your solar plant. Your solar company should be able to provide a detailed breakup of the total cost of your plant.

However, a major chunk of your total installation cost is related to setting up the solar panels on your rooftop. A typical install takes 4-6 hours, depending on the design and size of your solar structure. Hence, the installation cost might fluctuate based on the time required to set up the entire solar panel plant and the complexity of the job.

Facts About On-Grid Solar Power Systems

Know more about what an on-grid solar system is and how you can benefit from it:

  • The primary 1 kW capacity solar system can generate an average of 4 units a day, which means 120 units a month – amounting to 1,440 units throughout a year.
  • In an on-grid solar system, the components are covered under product warranties. The solar arrays mounted on your roof will have 25 years of performance warranty. Other components like the inverter and batteries will have 5-10 years of warranty, depending on the manufacturer.
  • Several solar companies also provide exhaustive maintenance services under the solar AMC package to help homeowners maintain their solar systems throughout their 25 years of lifespan.
  • The benefits of net metering will apply to this type of solar system, meaning you will be able to draw energy from and transfer energy to the local grid.
  • The MNRE allows residential solar buyers to purchase their on-grid solar system from any vendor of their choice and get a 40% subsidy on the grid-connected solar system of up to 3kW capacity.

Subsidies Offered on On-Grid Solar Systems

Eligible homeowners can get a 40% subsidy for rooftop solar installations of up to 3 kW capacity model. The subsidy rate is capped at 20% for on-grid solar system models ranging from 3 kW to 10 kW. There is no subsidy for plants of over 10 kW capacity, which is suggested for large homes with high electricity requirements.

The government of India is encouraging residential solar installations across states by offering subsidies to individual homeowners and housing societies. The solar subsidy is only applicable to grid-connected solar systems (without battery backup). Most homeowners consider the upfront prices of on-grid solar systems in India a great financial burden. However, subsidies can reduce the overall cost of your solar plant, while the rest of the cost is offset by the financial benefits of solar electricity.

Here is the typical rate of subsidy that is applicable on the benchmark cost or cost arrived through tender (whichever is lower) for RTS systems of different capacities.

System Capacity (kW) Solar Subsidy (in %)
1kW to 3kW 40%
4kW to 10kW 20%
More than 10kW No subsidy

Unlike earlier, the choice of solar vendors available for households is not limited to the channel partners of your local DISCOMs. Under the revised solar scheme issued by MNRE, individual solar buyers have the free will to select their own solar company in India and still be eligible for subsidy. Your solar company will customise an on-grid solar power system based on your power requirements and budget. To avail solar subsidy, you can apply with your local DISCOM and inform them about the details of your intended solar installation. 

Remember that both the Central Government and State Nodal Agencies (SNAs) are providing subsidy schemes for getting rooftop PV systems. As a result, the overall financial assistance might vary for you depending on the location of the solar installation. The other perks offered by the government include generation-based incentives, wherein the consumer receives some monetary incentive for each unit of electricity generated. Furthermore, the consumers can also transfer excess electricity to the government grid and receive credit per the regulated tariffs set under net metering.

FAQs about On-Grid Solar Systems

How much area do I need to install a 1 kW system?

Installing a basic 1 kW on-grid solar system requires a ten sq. metres area, getting no shadow from trees or adjacent buildings. However, the exact requirement may vary based on the efficiency of solar panels, the mounting structure, etc.

Does the area have to be shadow-free for solar module installation?

Unfortunately, yes. The solar cells within panels need unhindered and continuous sunlight to generate electricity at their peak efficiency level. Therefore, the shadow cast on even a small area on the panels will impact the on-grid system’s total capacity. Moreover, if some cells constantly receive shadow, this reduces the lifespan of your solar panels substantially, rendering them useless over time.

Is my roof suitable for installing a grid-connected solar system?

Yes. Generally, a rooftop solar plant can be easily installed on any type and size of the roof, given that the structure is strong enough to bear the weight of a solar plant. A roof assessment by your solar company will help you rule out all the major roadblocks to getting solar. 

Will my RTS generate the same amount of energy output all year round?

No. Several factors determine the daily energy production from on-grid solar systems for homes. The temperature during different weathers, solar radiance, location, and many other parameters can reduce and even increase the daily output beyond the standard range.

Will my on-grid solar power system give the same annual energy for all 25 years?

No. Your solar modules suffer degradation, and eventually, their peak generation capacity is compromised due to constant exposure to sunlight and daily wear. However, you can expect them to stay in their best condition for the maximum duration of their lifespan. Nevertheless, you can rest assured as your installer will cover your solar panels under a performance warranty.

Is maintaining an on-grid solar system for home costly?

Solar PV technology is the most suitable power generating system for homes as it’s affordable and easy to maintain. You can keep your solar plant in its best condition throughout its 25 years of lifespan with little maintenance and servicing. Your solar company should also be ablse to offer ongoing packages to take the hassle out of your system’s regular maintenance needs.

I live in a rented house. Is on-grid solar system installation beneficial for me?

Yes, renters too can go solar. Even if you don’t own the house, you can still leverage solar benefits. You can either convince your landlord to transition to solar, invest in community solar, or lease your solar plant that comes with zero or no upfront cost or maintenance hassle.

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.

How to Plan Solar Panel Installation for your Home

April 18, 2022 No Comments
Solar Panel Installation for your Home

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

March 1, 2022 No Comments
Impact Of BCD Hike On Residential Solar Sector

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 Cost-effective is it to install solar at home the Long Run?

February 2, 2022 No Comments
Cost effective solar installation

A residential solar energy system is a smart investment that comes with the promise of guaranteed long-term savings. Despite the high upfront cost, the expenditure or you may call it an investment is offset in just the initial few years through sizable energy output, significant net cost savings, and a hassle-free maintenance experience. In addition to being a clean, renewable source of energy that eliminates carbon footprint, solar energy is actually getting more affordable and rewarding than you think.

Cost of Installing a Solar Panel at Home

The average cost of a residential solar panel installation varies from state to state in India. Several state governments are offering financial support and subsidy schemes to make the cost of rooftop solar installation affordable for as many homeowners as possible. Here is a sample of the subsidy structure by IPGCL  (Delhi DISCOM) for their last tender (May 2020) for residential rooftop solar systems. 

SOLAR SYSTEM SIZE (KW)  SUBSIDY BENCHMARK COST (BM)
1-3 40% of BM cost Rs: 37000/ kWp
3-10 20% of BM cost Rs: 32,400/ kWp
10+  Subsidy for first 10KW only Rs: 32,400/ kWp

In earlier times, a small capacity solar PV system used to be enough to power a home. In the current times, India’s domestic energy consumption per capita is increasing and we use a lot more units of electricity today than in the past. Apart from the usual home appliances that we use, we use a lot more heating and cooling devices, smart devices, electric vehicles than before.  Hence, a 3 kWp solar system generating 12 to 15 units per day is the minimum you would need to run your home efficiently. For a bungalow with 4-5 ACs or a big farmhouse, a 5KWp system or above would be a better choice.

Maintenance of Rooftop Home Solar Panel

Routine maintenance of your solar batteries and the solar PV system will allow timely detection of potential repairs, security concerns, and signs of damage. Have your solar installer inspect the system’s wiring and electricals at least once a year. The preventive maintenance would involve inspecting fittings, electrical conduits, visible electrical hardware, and ground conductors as well. You will also need to keep your glass PV solar modules clean of any dust, debris, or bird feces that may accumulate over time. Make sure to clean your PV modules with a wet cloth once a month or every fortnight if you live in dusty areas for optimum generation. Note that the solar system should be on switch off mode when you attempt self cleaning. 

Your rooftop solar system uses a kind of mild steel rack system to be mounted. Cleaning and checking the racking for signs of damage, loose hardware, and debris accumulation should be performed once every year to prevent any uprooting of solar panels from the racking during an event of extreme weather like a storm or heavy rains.

Your solar batteries also need professional maintenance to ensure efficiency and extend their life. In addition, a little upkeep done routinely will keep your batteries in good condition. During winter, your lead-acid batteries will also need a refill of distilled water every 2 to 4 weeks. Also, monitor the battery charge, and if found flooded, apply an equalization every 90 days. 

Energy Output of Solar Panel

Power output is a key factor in selecting the right residential solar panel system. Also, when installing a solar system in your home in India, the price you pay is based on the proposed solar system capacity per kilowatts. 

Calculating the accurate electricity generated by a rooftop solar PV system can be a complex math exercise, but you can estimate it yourself for your home if you know your monthly electricity bill through various solar calculators. In the Indian scenario, for every 1 KWp of solar system,  an average of 4 kWh (units) will be generated per day, accumulating to 1,400 to 1,600 kWh in a year. This estimate may differ from the actual generation as meteorological conditions affect solar power generation capacity. Many other factors like the home’s location, the orientation of the roof, solar panel efficiency, and ambient temperature affect solar energy production, which is taken into account by the solar installers when they give you the first proposal after the technical assessment or a site visit. 

Net Savings in the Long Run

The overwhelming 6-figure cost of a residential solar panel installation keeps most homeowners on the fence. Investing in rooftop solar installation also brings attractive returns and eventually the system pays for itself with the huge cost savings in the electricity bill. With a grid-connected solar system, you will not only do away with fluctuating electricity prices but can also earn electricity unit credits via net metering by sending any excess power generated back to the grid. The DISCOM will then charge you only for the net units consumed in a particular month thus reducing your electricity bill by a great extent.  

Thanks to the little maintenance and a life expectancy of 25-30 years, you can expect a payback period of just 5-7 years on most solar PV systems available in the market. The Internal Rate of Return (IRR), expressed as the percentage of return on investment (ROI), represents the rate of returns you expect to receive on your solar panel installation cost. 

Suppose you make an investment in buying solar for your home. This investment would not only pay for itself but you get your electricity for free after the payback period is over. With advancements in technology, PV modules of higher efficiency are being developed which gives even more savings and generation through your residential solar panel systems.

How to Prepare Your Rooftop Solar Panel for Winters

January 5, 2022 No Comments
Rooftop solar panel during winters

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?

Innovations in solar energy for personal use

February 24, 2021 No Comments
Solar powered gadgets

Did you know that there are T-Shirts that activate in sunlight? Although they don’t have any solar-related components, just a special dye and treatment displays the design only in the sun.

Such innovations have always created a buzz and sometimes even helped the product succeed in the market. Solar energy for individual use has also witnessed multiple innovations across product categories.

Solar powered gadgets

Solar-powered calculators and watches are among the first handheld consumer devices to run on solar power. Since then, we have witnessed that almost all appliances used at home can be powered by solar. Everyday gadgets such as solar-powered power banks, security cameras, security locks, laptop keyboards, speakers, garden lights, and many more gradually started appearing in the market.

On the other hand, the use of solar energy in the residential segment has undergone a stark shift from the early days of solar cookers and solar water heaters to the present day where solar energy can be used to power an entire house.

ROOFTOP SPACE:

As per India RE Navigator, residential solar currently accounts for 14% of the total rooftop solar installations in India, which is dominated by Commercial and Industrial segments. With solar for home requiring rooftop space which is not abundantly available, considering the high-rise in urban cities, it is thus necessary to innovate to address this issue. In the U.S, Tesla has come up with a solar-roof, an alternative to the traditional tiled-roofs serving a dual purpose of the roof as well as getting the benefits of solar without the need for additional space. Although this is best suited for individual homes, it addressed the concern of allocating some additional shade-free space.

WINDOW SOLAR CHARGER:

Another interesting innovation is by a startup named Grouphug Solar, which has come up with a modified version of mobile chargers. Their window solar charger can just be hung on any window with incident sunlight and used to charge their mobile phones. Although it won’t power the entire house, it is a way to bring solar to people who otherwise cannot access it. In order to serve the commercial segment, they even launched custom solar panels  where they have installed quirky designs suited to the vibe of the place. One such design is what they call as the SOLARCAT. 

Solarcat

FUTURE OF SOLAR:

With Design Thinking principles encouraging the adoption of Human-Centered approach to problem-solving, the world has seen multiple innovations supported by ingenious designs. It is now the time for solar to reach every individual in one manner or the other with the help of such schools of thought. It helps people make a conscious effort to contribute positively to the environment and at the same time benefit out of it, which allows them to understand the discourse on sustainability and its power to influence their livelihoods. This ideology is based on Julian B. Rotter’s 1954 concept of Locus of Control which mentions how a high Internal Locus of Control (the belief that the action that I take as an individual affects the society) can help solve a lot of problems in the world. Solar is here to stay and only needs nudges to be adopted by the larger population.

Can you run a house completely on Solar Power?

February 20, 2021 No Comments
Residential Solar panel

An answer to the question, whether you can run a house completely on solar power is yes! Especially in a country like India where we receive abundant sunshine throughout the year, it is convenient and beneficial to have residential solar systems.

Going completely solar you can reap good benefits but there can also be some potential drawbacks which are inadvertently attached to it. The best part about generating electricity through solar power is that it is completely free! The initial investment involves setting up the solar system can be a bit high depending upon your requirement. Solar power is quite efficient and is also free of pollution. But you must also consider the chances of foul weather that might cause a problem to your plans.

TYPES OF SOLAR SYSTEM:

There are two types of solar systems namely off-grid solar system and on-grid solar systems.

Off-grid solar systems:

Off-grid solar systems are the ones that work independently off the grid and have batteries which can store the solar power generated by the system. The system consists of batteries, solar panels, grid box, charge controller, mounting structures, and balance of the system. But there is always a chance of an extended bad weather condition might cause problems for your electricity supply.

On-grid solar system:

In On-grid solar system, if your system produces more power than is required, then the surplus can be fed back into the main electrical grid with the help of solar net metering and you can get credited for the same. Similarly, you can also use the traditional grid provided power during the situations when your system is not producing enough power.

UNDERSTANDING THE INFRASTRUCTURE:

While planning to run your house completely on the solar power, you need to also understand the financial and mental investment required. The infrastructure and working of a solar system are slightly complicated and hence the calculations involved should be precise. With the help of careful routing of a home’s plumbing, you can get hot water heated by the sun and since it is pumped through the house, the heat dissipated can be used to control the temperature of the house. The heat generated in this manner would also not add up to the home’s electric consumption. Although it might be a challenge to execute, in the year 2007, a successful experiment had shown how to heat and cool the house using a solar radiant heat system!

THINGS TO KEEP IN MIND:

Before finalizing to go completely solar, the first point to be considered is whether your house gets enough sunlight throughout the year to produce enough electricity. If your requirement is to run an 800-watt load for your home or less than 800-watt then 1kW solar panel is perfect for you. The solar panel installation requires 100 square feet of shade free roof space and to run the load, the first priority would be given to the solar system and second priority would be the grid or batteries. 1kW solar panel price in India for home depends upon the type of solar system.

The different types of 1kW solar systems include:

1. On-Grid Solar System:

Also known as grid-tied system as it connects with the grid electricity system. The solar system with 1kW capacity produces 4-6 units per day on an average. Solar net-metering is installed which reads how much electricity you are using and the balance which can be exported to the grid. All the adjustments are made in your upcoming bills by the government.

2. Off-Grid Solar System:

Off-grid solar system or stand-alone power system is also known as a solar battery-based system. This system has a battery as a backup which helps you store the solar power which can be used during power cuts when the sunlight is not available.

3. Hybrid Solar System:

Hybrid solar system is designed to have the functions of both the off-grid solar system and on-grid solar system. Basically, a hybrid solar system has three sources to run its load – solar energy, battery storage, and grid electricity. The best part about a hybrid solar system is that it stays connected with the government electricity grid and has batteries as a backup. It is most suitable for people living in areas that witness more power cuts, due to frequent rainfalls. The approximate cost of 1kW solar panel with battery storage in India ranges anywhere between Rs.80,000 to Rs. 1,50,000, including installation. While calculating the price also check whether you are eligible for the government subsidy ranging from 10% to 40%.

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

January 29, 2021 No Comments
solar panel installation

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.

solar panel installation

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!
