How Many Solar Panels Are Needed to Power a House?

No Comments

As every home has a different energy requirement, it is important to know how much kilowatt is required to address your home energy needs before finalising the number of solar panels you will need. Whether you want your rooftop solar system to meet 100% or some proportion of your home’s electricity demand, the decision will require you to define your objective of going solar first. Most people generally switch to solar to reduce their electricity bills while lowering their carbon footprint. 

To understand how many solar panels are needed to power your house, you need to analyse your average annual energy requirements, your current electricity usage in watts, and peak Sun hours in your region. Also, the efficiency and physical size of the solar panels you are considering can influence your home’s total count of solar panels in the rooftop solar system. 

Determine How Many Solar Panels Are Needed to Run a House

To calculate how many solar panels are needed to run your house you need to know the energy requirements of your house. This calculation involves three key factors. It’s true that the easiest way could be to ask a reputed solar company in India to perform a complete solar inspection and walk you through all the aspects of upgrading to solar so that you can make an informed decision. However, you can still do the math yourself by obtaining enough information. The basic formula is to divide the total solar system size by the production ratio and then by individual panel wattage.

You need to consider three main factors to get a near-accurate estimate of how much kilowatt is required for your home’s electricity demand:

  • Annual electricity usage
  • Solar panel wattage
  • Production ratios

Annual Electricity Usage

The first step to assessing how many solar panels are needed to power your house will require you to check the current electricity usage for a year. This information, measured in kilowatt-hours (kWh), can be easily found in your monthly electricity bills. Your annual electricity usage should factor in all areas of electricity consumption, such as all types of small and large appliances, lights, ACs, geysers, laptops, TVs and any motors. For the explanatory purpose, we will assume a household with an average electricity consumption of 6,000 kWh annually.

Solar Panel Wattage

All solar panels look and function alike, but they are not created to generate equal amounts of power. That’s why you must find out the home solar panels’ wattage before making a decision. The panel wattage represents each panel’s electricity production capacity. The standard range for solar panels wattage is between 250 to 400 watts. Depending on your energy requirements and budget, you can pick above or below the average panel wattage of 300 watts.

Production Ratios

The production ratio of a solar panel system is the correlation of its estimated energy output (in kWh measured over time) to its actual size (in W). This might appear to be a 1:1 ratio as it’s easy to believe that a system will always perform and generate power to its total capacity. However, fluctuations arise depending on the amount of Sunshine falling on your home. As a result, the ratio varies.

For instance, a 10kW system that generates 16kWh of electricity annually will have a production ratio of 1.6. The regions with long days and ample Sunshine will see a better production ratio than those with much rainfall and fewer hours of Sunshine.

The Formula for Finding How Many Solar Panels are Required for Home

Now that you have the required information handy, put the figures in the following mathematical formula to determine how many kWs are required to power your household. 

Number of panels = system size/production ratio/panel wattage

Now, if we put the figures we have estimated so far, the number of panels can be calculated as 6,000 kWh / 1.6 / 300 W. This equates to 10 to 15 solar panels that are enough to power a medium-sized home. So, now you can put your house’s unique values to determine how much kw is required for your house. 

A Different Way of Finding Estimated Solar Use

If you don’t prefer this approach to finding how many solar panels you need to fulfil your electricity demand, a simpler way would be to evaluate your monthly utility bills. They tell you how much energy you are consuming. Now multiply the energy usage figure by the total number of strong sunlight hours your intended solar installation location receives. Divide the figure thus obtained by the wattage of the panels you are planning to buy.

Factors Affecting How Much Kilowatt Required for Home

Although the above calculations will give you a near-accurate estimate of how much kW is required for your house in India, there might still be more to think about. Here are some of the factors that can influence the number of solar panels for your intended location.

System Efficiency

Even the most efficient solar panels can’t do the job of absorbing Sunshine and generating energy at their top capacity levels at all times of the year. Many weather conditions hinder the working of solar panels. On days when sunshine hours are reduced due to rainfall, a cloudy sky, or winter, these are the days when you’ll need a few additional panels to be able to generate just enough energy your home needs. Hence, experienced solar panel installers are likely to add an additional 25% more over the standard number of solar panels needed in your rooftop solar system.

Hours of Sunlight

Clearly, solar panels require an uninterrupted supply of Sunshine to generate ample amounts of energy. Hence, you must determine the amount of Sunshine you get every day. If sunshine hours are less in your region due to weather or geographical conditions, you’ll need more panels to increase the amount of Sunshine captured in a day by your solar panels.

The Wattage of Your Panels

As discussed earlier, the wattage of solar panels varies from 250 to 400 watts per panel. If you choose to install lower wattage panels, you would need a higher number of panels to generate ample power to meet your home’s energy requirement. Of course, this depends on whether you are aiming for 100% conversion of your energy usage to solar energy. However, if you only hope for a partial conversion, then you wouldn’t mind settling for fewer panels of low wattage.


After the question of how many solar panels are needed to run a house, you would certainly be concerned to learn about the prices. Before you decide what solar panels to pick, it’s important to evaluate your budget and how much you are willing to spend on your home solar systems.

Does Solar System Type Affect How Much Solar Panels I Need for my Home?

Rooftop solar panel systems are available in three different options: on-grid, off-grid and hybrid systems.

On-grid solar systems are the type of solar power framework that is tied to the grid and can transfer solar electricity to the government. The only key components making up this type of system are solar panels and the solar inverter. A grid-tied network is the simplest and most budget-friendly type of home solar system as you don’t have to buy any additional solar panels.

On the other hand, off-grid or stand-alone solar system owners are required to go for a lot more solar panels. This is because the type of solar system is responsible for generating enough electricity to meet day-to-day demands and charging solar batteries, which is an important component in this type of solar system.

A hybrid solar system is connected to the grid and has solar batteries to keep your home powered during an outage. For this system, the solar developer will recommend adding the maximum number of solar panels to meet your electricity requirements.


Will I continue to get an electricity bill after switching to solar?

Once you have added solar panels to your rooftop and enjoy green solar energy, the generation of a monthly electricity bill will continue as long as you are connected to the grid. However, you can expect a reduced/zero or even a positive solar credit balance if your electricity exports to the grid exceed any electricity imports for the month. 

Is it possible to increase the solar system size after installation?

It’s always possible for homeowners to add more solar panels and increase the size of their home solar system if the current system size falls short of their home electricity requirements. This will help them further reduce the cost of electricity and unveil the great solar benefits for your home.

What is solar panel efficiency?

The efficiency rating of different solar panels represents the amount of Sunshine that solar panels absorb and turn into usable electricity. A higher efficiency rating means you’ll need fewer solar panels to generate ample energy with fewer panels. For example, the 15% efficiency rating of solar panels means that 15% of Sunshine that hits the solar panels will be used to generate electricity.

Are solar panels costly?

In a rooftop solar system, solar panels are the most costly component that holds the highest share of the overall upfront cost of home solar systems in India. However, the cost of solar panels can vary depending on the energy efficiency rating of solar panels.

I need a 24 hours electricity supply. How much kW is required for my house?

Solar production is intermittent for the simple fact that the Sun doesn’t shine around the clock. As a result, solar electricity isn’t available at night. Luckily, the problem can be easily resolved by adding solar batteries that can consistently maintain enough reserve of solar energy for later use. 

Are solar panels worth it?

Given the current environmental crises, solar is certainly the only way forward. However, the individual decision to adopt solar will depend on your electricity prices, daily energy usage and your desire to choose an environmentally-friendly energy source. Considering all these factors in combination with your home’s geographic location can show you how favourable solar panel installation will be for you.

How long does it take for solar panels to pay for themselves?

Despite the high upfront solar investment, modern solar panels, in most cases, have a commendable pay-off of 6 to 8 years while reducing the cost of electricity for your home for the rest of the 25 years of lifespan of solar panels.

How much do solar panels weight?

Depending on how many solar panels are needed to power a house, installing solar panels will add additional weight to the roof. There are several options for homeowners to design a unique mounting structure for their panels creatively. Hence, it is important that you ensure the integrity of the roof so that it can bear the burden of solar panels for the next 25+ years.

Do solar panels require a lot of maintenance?

Maintaining solar panels is much easier as the structure doesn’t have any moving parts, which eliminates the chances of any functioning failure. In addition, with the right panel cleaning routine, you can maintain the efficient functioning of solar panels and prolong their life.

Is my roof suitable for solar panel installation? 

Depending on how many solar panels are needed to run your house, you will need ample space free of any shade cast by neighbouring trees or buildings to install solar panels. Shade hinders the solar panel’s ability to absorb Sunshine and efficiently lowers energy output. Even a small shaded area on one panel can bring down the efficiency of all the interconnected panels.

Solar Power Plant: Types, Working, Benefits, Technology & More

India receives ample sunlight throughout the year. It is time to leverage it by installing a solar power plant and producing your own electricity while taking a step towards a greener future. In addition to government subsidies, there are many advantages of a home solar system that will convince you to switch to a cleaner energy source today. 

If you are looking for complete solar power plant information, here is a good place to start. Follow this blog as we discuss what a solar power plant is, how a solar power plant works, and eventually answer your frequently asked questions.

What Is a Solar Power Plant?

Solar is the most remarkable alternative energy source that is good for the environment. It can be made easily available to individual homeowners by installing a solar power plant for your home. In a solar plant the solar panels have the main function of generating electricity. Modern panels are highly efficient, meaning a few panels can produce considerable electricity to power your home. 

Moreover, the incredible financial benefits of the solar power system give long-term money savings (for over 25 years), especially by reducing monthly electricity bills. Through these advantages, most systems can pay you back on your initial investment within just 6-8 years of use.

Types of Solar Power Plants

Wonder how many types of solar systems are there for your home? The answer is three – on-grid, off-grid, and hybrid solar systems. Learning about each will help you decide which system is right for your home.

More and more homeowners are getting attracted to the potential and benefits of a solar power plant for home. The biggest motivation is solar power’s ability to bring significant long-term savings on monthly electricity bills. However, the process of going solar involves making important decisions, and selecting the right option from different types of solar power plants is one of them.

Each type of solar system is unique, includes certain additional components, and varies in the initial investment required to purchase solar.  

  • On-grid or grid-connected solar system
  • Off-grid or stand-alone solar system
  • Hybrid solar system

Off-Grid Solar Power Plant

This type of solar system is not connected to the grid and relies on solar batteries to ensure power supply.

As the name suggests, you are completely independent of the local grid with an off-grid solar power plant for your home. Going off-grid means that you rely entirely on the power generated from your solar panels and also use battery backup to maintain a power reserve for use when solar energy production falls below the standard capacity.

This stand-alone system is ideal for homes that don’t have access to the local grid and are located in remote areas. An off-grid structure is quite expensive because of the battery pack to store solar power thus generated. 

Working of an Off-Grid Solar Power Plant

A stand-alone system has a higher number of solar panels to produce electricity to meet your home’s daily consumption and maintain an energy reserve in your batteries.

Using an off-grid solar power plant means absolute grid independence for homeowners. In this solar structure, you’ll always have enough power backup in your batteries to meet your home’s electricity demand when solar energy production falls short, especially at night.

There is a higher number of solar panels in an off-grid unit as compared to the on-grid structure. These panels generate a significant amount of electricity to not only meet the home’s electricity needs but also charge the batteries fully. Also, this type of solar system is installed as your home’s main utility system, which increases the installation cost.

Benefits of Off-Grid Solar Plant System

  1. Independence: Absolute grid independence can be a great advantage with an off-grid solar power system. You generate and use your own power and aren’t tied by the terms and conditions of using grid electricity. 
  2. No blackouts: Unexpected and prolonged blackouts will not affect your home when the grid is down. You will always have a predictable power supply when everyone else waits in the dark for the grid to resume supply.
  3. No electricity bills: Since you are not connected to the grid and are entirely using your own solar electricity, you don’t have to deal with the utility company and pay any monthly electricity bills. 

On-Grid Solar Power System

An on-grid solar power system is the one that is tied to the grid and is governed by the provisions of net metering.

A grid-tied or grid-connected system is the most common solar system found in homes, and is highly cost efficient. An on-grid solar plant system is connected to the local power grid so that homeowners can draw electricity from the grid when solar energy generation is low. Whereas, when there is surplus energy production, unused electricity is transferred to the grid and homeowners are issues solar credits which can be redeemed later when the billing cycle gets over.

The key components that an on-grid solar power system contains are solar panels, a solar inverter, and a bi-directional meter to facilitate the net metering. Homeowners don’t have to invest in solar batteries, making on-grid the most cost-effective among all types of solar systems

How an On-Grid Solar Power Plant Works

Net metering is a key component in the working of solar power plants. You enjoy the flexibility of drawing electricity when needed from the grid and also earn solar credits by sending your unused solar energy to the grid.

An on-grid solar plant system generates ample electricity during the day to meet your home’s electricity needs. However, when solar energy falls below the standard generation capacity, you can draw additional electricity units from the local grid via the net metering system. Your home solar system is designed to often generate electricity beyond your daily consumption. The extra electricity that your home doesn’t need is sent to the local grid. Under net metering, the meter measures and bills both the import and export of electricity, which is reflected in your monthly electricity bills.

Benefits of On-Grid Solar Power System

  1. Initial cost: Among the different types of solar power systems, purchasing an on-grid solar plant solar power system is the most cost-effective option. Homeowners need fewer components to set up a grid-tied system.
  2. Low maintenance: Once the system is set up, homeowners don’t have to invest a lot of money or effort in the operation of grid-tied systems. Most installers cover your Solar panels with 25 years of warranty and provide AMC (annual maintenance charges) maintenance packages.
  3. Reliability: Grid-tied systems are easy to install and are more reliable, having minimal downtime (days without electricity).
  4. Flexibility: Modern on-grid designs allow homeowners to start with a basic system and upgrade it by adding more solar panels or batteries, giving you the flexibility to meet future needs.

Hybrid Solar Power System

Hybrid solar power systems become an easy choice for homeowners wanting to do away with power outages as the structure includes the perks of both on-grid and off-grid systems.

A hybrid solar power system has the advantages of both on-grid and off-grid designs. Homeowners enjoy the flexibility of the government grid via the provision of net metering similar to a grid-tied system and also get sufficient battery backup like an off-grid unit.

A professionally designed hybrid solar structure gives you the dual benefits of reduced energy cost and reliable, 24/7 electricity supply across all weather conditions. The key components in a hybrid solar power plant include a PV array, batteries, a solar inverter, a charge controller, and an optional tertiary power source like a power generator.

How a Hybrid Solar Power Plant Works

The sun’s energy absorbed by solar panels generates electricity direct current which then passes through the solar inverter to convert into usable AC. This type of solar power system is designed to generate surplus energy beyond your home’s daily consumption. When solar energy production is at its maximum, the excess units go towards charging solar batteries. When the sunshine is not available for generating power due to the winter season, cloudy days, and also during the night, the energy stored in the batteries is used to compensate for the shortfall in production.

When the batteries are fully charged, the further generated units go to the grid for which you are compensated. If you still have extra energy after meeting the home’s energy demand and the charging batteries, these units are transferred to the grid. You can also import electricity from the grid if you face low solar electricity production and low battery charge.

Benefits of Hybrid Solar Power Plant

  1. Energy storage system: You will not be impacted by power outages as your home solar power system produces electricity beyond your daily energy consumption to maintain energy reserves. During unfavourable weather, when the grid is down and solar energy is reduced, you’ll still have several hours of electricity in your batteries.
  2. Save money in the long run: Adding batteries to your home solar system ensures that you save a lot of money by depending more on your home-generated solar power instead of drawing power from the grid.

Technology Behind Solar Power Plants

Solar or photovoltaic cells, the technology behind solar panels, are remarkable power generators. As light falls on the solar panel cells, they absorb photons and release electrons. These loose electrons are captured to create electric current or electricity. This entire process of electricity generation from light is called the photovoltaic effect. 

Solar cells making up an entire solar panel are manufactured from semiconductor materials, often silicon. This material is responsible for releasing electrons as light hits the surface and then channels these electrons into an electric current.

A typical single-junction PV cell can produce a maximum of 0.5 to 0.6 open-circuit volts. This voltage power amplifies as thousands of solar cells are combined into a solar panel, which are further arranged into large arrays (groups of solar panels). These extensive series of interconnected solar cells across an array can generate renewable energy in significant amounts.

Components of a Solar Power Plant

The composition of a home solar power system is not particularly complex. A standard system is made up of a few basic components. The key components of a solar power plant include:

  • An array of solar PV panels mounted on a racking system
  • Solar inverter
  • Bi-directional meter

Solar panels are the primary component in the working of solar power plants. They collect and convert sunlight into solar electricity. This DC power is fed into the solar inverter and gets converted into AC electricity, ready to power your home appliances and electronics. Various switch boxes are also included in the structure to ensure safety, and the entire solar structure is put together using wires and conduit. A battery pack is included in an off-grid solar plant to ensure a reliable supply of electricity in the home when there is no grid nearby or in case of an outage.

Benefits of Solar Power Plant for Home

  1. Energy savings: The most important advantage of using solar power plant is that you gain a cheaper and more reliable power source than the grid electricity. Solar systems are easier to maintain and saves you money by providing low-cost electricity. You can also earn solar credits received by exporting excess solar power generated back to the grid. 
  2. Adds to your home’s value: A home with its own power bank becomes an attractive purchase for home buyers. As you inform the potential buyers about the cost-savings they will enjoy with a solar-powered home, you will be able to get a better price for your property.
  3. More reliability: Several homeowners complain that their local grid supply is not reliable. Frequent grid failures, especially during inclement weather and unexpected outages lasting several hours, disrupt their routine. With solar power system with a power back up (off-grid solar plant), you have a reliable energy source that helps you keep up with your daily routine without any obstruction from the grid.

How to Choose a Solar Power Plant for Home

If you are ready to generate your own power but confused about picking the right solar setup for your home, the following guide will help you make a decision.

Off-Grid  = Saving + Battery Backup

Off-grid solar power systems are a clear choice for homes that do not have access to the local grid or don’t receive a reliable electricity supply. An off-grid system will enable the homeowner to become grid independent and use batteries to ensure power availability at all times.

On-Grid = Saving + Net Metering advantages

On-grid solar power plants can help you do away with high monthly electricity costs. Moreover, it gives you the flexibility to draw power from and export surplus energy back to the grid.

Hybrid = Saving + Net Metering + Battery Backup

Go for hybrid solar plant systems if you want the benefits of net metering, resolve the problem of high energy costs and outages, and the reliability of a battery backup.


How do I find out how much my current electricity bill is?

It’s easier to calculate your monthly and even annual electricity costs from the monthly electricity bills. Whether you want to understand the per-unit cost or how much you pay annually, you can figure it out from the bill you receive from the DISCOm or have your solar power plant installer decode it for you.

What is net metering?

The net metering system regulates the two-way electricity flow between a grid-connected solar plant system and the DISCOM grid. It credits the solar power system owners for exporting solar electricity to the grid and charges for withdrawals from the grid. Both the import and export of electricity are recorded in your monthly bills, and the homeowner apys for the net units or electricity they consume.

Do my solar panels generate electricity when the sun isn’t shining?

Your solar panels require uninterrupted sunshine (and not heat) to generate electricity. The daily power generation of your solar plant system will be affected when the weather is cloudy or at night when sunshine isn’t available. However, the overall financial advantages still make solar a smart investment.

Am I eligible for a subsidy on my home solar power system?

Homeowners are eligible for government-provided solar subsidies on purchasing a grid-connected solar power plant for their homes. A 40% subsidy is available on a rooftop unit of up to 3 KW capacity. Systems with a capacity of over 3 kW and up to 10 KW will be able to apply for a 20% subsidy. You can get your solar system from any vendor of your choice and still benefit from solar subsidies.

Can I go solar if I can’t afford the upfront cost of solar?

If you can afford to pay high electricity bills every month, you can easily afford to switch to solar. Solar financing options such as a solar lease and solar loan can help you easily get a solar power plant. An experienced solar installer can help you compare the cost of home solar systems, provide multiple financing options, and savings throughout the lifespan of your system. 

How do I decide the right size of solar power plant for my home?

Selecting the right size of solar energy system depends on your monthly electricity use and the annual weather conditions. The solar installer will also inspect your roof to assess the amount of sunshine you receive on average. Keep your monthly electricity bills for at least a year handy before scheduling your solar consultation. 

Will I get a warranty on solar components?

All key components in your home solar power system come with manufacturer’s warranty coverage. Your solar panels will have over 25 years of performance warranty, while the other components will have 5-10 years of warranty depending upon the manufacturer. Moreover, your solar company can also provide AMC maintenance packages to help you keep your system at optimum performance levels at all times.

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

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.

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. HomeScape by Amplus Solar is a solar installation company serving in Delhi, Gurgaon and several regions of India and is committed to helping homeowners make a smooth and highly beneficial solar transition.

Energy Efficiency Site Survey Solar Energy solar for home

Why is a Site Survey required prior to installing a Solar Rooftop System?

No Comments

Solar rooftop systems and other sources of renewable energy are on the rise. Residential rooftop solar systems have proven to be environmentally sound and efficient for domestic households, along with monetary benefits such as saving on electricity bills and government subsidies.

Solar panels are generally placed on a rooftop or in an elevated position to ensure a steady and consistent supply of sunlight. This sunlight is then converted to DC electricity and then into AC electricity by an inverter.

To ensure domestic solar systems perform at optimum capabilities, solar providers must consider a variety of factors before going ahead with the installation. A Site Survey prior to installation gives service providers all the information they require to correctly install and operate a residential solar system, tailored to every customer’s specific needs.

The three main factors assessed during a site survey are:

  • Feasibility – is the solar plant installation feasible at the location?
  • Viability – does the solar installation provide financial benefits in the long term?
  • User requirements – are user requirements correctly understood?

Site surveys ensure that you have a rooftop solar power system designed specifically for your needs as per your location, rooftop space and the electricity required to power your home. HomeScape has three unique product variants that are tailor-made to fit your space: the Atrium, the Aerial and the Terra.

During a site survey our team determines the following factors:

  1. Shading Analysis

This helps determine the correct location to install a solar plant. The orientation and mounting of the solar panels determine the amount of incident sunlight which in turn contributes to the amount of electricity generated. The solar panels need to be shade-free to get the optimum performance from the solar photovoltaic system. The area must be assessed to ensure there are no barriers that cause shading on the panels.

  1. Roof Structure Inspection

This is done to measure the size and to determine the attributes and structure of the roof. The rooftop area and size of the panels determine how many solar modules can fit in the space available. We consider the following factors:

  • Surface Area (rooftop dimensions)
  • Roof Inclination
  • Roof Direction
  • Construction Material
  1. Usage Analysis

This is the overall analysis of required instruments such as DC and AC converters and electricity usage. This helps determine the overall generation of electricity and an estimate of the units of electricity that can be saved.

  1. Financial Analysis

Government has released many incentives and financial aids for the solar panel system users. The overall cost of installing and the economic viability of the system are other important parameters that are estimated during the site survey.

Conducting a site survey is the starting point for a rooftop solar power system installation for a home in India. Your site survey results and shading evaluation in combination with the energy audit helps you make an informed decision about switching to solar.

Can you run a house completely on Solar Power?

No Comments

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.


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.


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!


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

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.

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


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.


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!
