Solar Rooftop System for Home: The Ultimate Guide

In recent years, the awareness of the solar rooftop system for home has attracted the masses. The sun is one of the largest free sources of energy available on earth. The energy from the sun is available in an ample amount. And unlike conventional ways of electricity production, the process of producing electricity from the sun is an environment-friendly method. Plus, as compared to all the other sources of energy, the application of solar energy is much easier. 

The government bodies are also supporting this industry by introducing subsidies and policies to expand the awareness & demands of solar products. In several urban & rural areas of India, millions of homes have solar rooftop systems installed on their roofs. Read this article until the end. Here we will discuss all the different aspects of the solar rooftop system. All the things that you must know will be covered in this post. 

Solar Rooftop System for Home: The Ultimate Guide

Solar Rooftop System for the Home: Why do We Need them?

The energy from the sun is free. And harnessing it and converting it into usable electricity is also very cost-effective too. It only comes with some initial investment, and after that, it will serve you for more than 25 years. Almost every solar panel manufacturer is also giving a warranty of 25 years on solar panels.

Moreover, you can also supply the excess electricity produced from the rooftop system to the electrical grid (Grid is an electric network through which the electric power is coming to your home) too. And in some cases, the electricity board may even pay you for your contribution to electricity. Before more questions arise in your mind, let’s discuss how the solar rooftop system for Home works?

Working of the Solar Rooftop System

Let’s discuss the principle of the solar rooftop system in steps.

  • At first, the system starts with the installation of solar panels on the terrace of your home or any commercial & residential buildings. The solar panel works on the principle of photovoltaic. In simple words, when the sunlight falls on solar panels, the solar panel converts it into electricity.
  • When solar panels are in direct contact with sunlight, the flow of electrons takes place inside them. The flow of electrons becomes the flow of electric current (DC direct current). And it can be extracted using the wires or cables that come out from the solar panels.
  • And here is one thing, all the appliances at our home are designed to operate on alternating current (AC electric power). And the electricity produced by the solar panel is DC electric power. Hence a device called an inverter is used to convert the DC electric power into AC electric power.
  • The converted AC power will flow through a metering system. This system will keep track of how much electricity is used for your home? And how much energy is supplied by you to the electricity board’s grid? 
  • And through the metering system, the electric power is fed to the appliances of your home. 

Above was the system that the majority of households go with, and that system is called an on-grid solar rooftop system. If you do not want to supply electric power to the electricity board, then there is an off-grid solar rooftop system too. In this system, the battery is used to store the excess energy from solar panels. The stored energy in the battery can be used when there is no electric power available from solar panels (Night, evening, and rainy seasons).

Is your Roof Suitable for this System?

The suitability of your roof also plays a huge role in installing the solar rooftop system Your roof should be big enough to bear the requirements of the system. The total number of panels to be installed on the roof is calculated on the basis of the requirement of total electric power for your home. Higher the power requirement, the higher the number of panels will be required. There should be enough space on the roof to cover all the panels.

The panels should be installed facing the south direction. India is located in the northern hemisphere. Hence, to get the maximum benefit from the solar rooftop system, it should be installed facing the south direction. If your roof is naturally facing and sloping towards the south, that would be an ideal situation for your rooftop system.


So it’s time to stop paying the electricity bills and let the electric boards pay you. The one-time investment in the solar rooftop system for the home will save you from the burden of years of electric bills. Moreover, by installing this system, you are leaving a positive impact on the environment too. Solar energy is the largest source of clean energy. 

As an aware citizen, it’s time to invest your money for the environmental cause. By giving the huge subsidies for installing such systems, the government is also promoting this system. It’s time to change, let’s make India even greater by utilizing all the free forms of energy. Thanks for reading till the end.
