To reduce the electricity bills of homes and businesses, people are planning to install rooftop solar in India. India had a target of 100 GW of solar installations by 2022 across the country, with 60 GW in commercial and industrial sectors and 40 GW in residential sectors, but this target has been revised by 2030. The average installation capacity of rooftop solar is 1 GW monthly and 12 GW yearly.

What is a rooftop solar system?
The meaning of rooftop solar is that “a solar panel installed on the roof of a building is called rooftop solar.” This category includes residential homes, commercial buildings, government buildings, group housing societies, manufacturing plants, educational institutions, healthcare facilities, and more. A small unit of solar installation starts from 3 kW to 10 kW in residential sectors, 10 kW to 100 kW in commercial sectors, and above 100 kW installation in industrial sectors. The Indian government provides incentive schemes to boost rooftop solar installation in these sectors.
How does the rooftop solar system work?
A solar power system has three main categories: grid-connected solar system, stand-alone solar system, and hybrid solar system. A grid-connected solar system is also known as an on-grid solar system, which is used to save (reduce) electricity bills, whereas a stand-alone solar system is also known as an off-grid solar system, which is used to generate electricity anywhere as well as save electricity bills, and a hybrid solar system is a combination of both systems. This solar system gained popularity because of lithium batteries. Under the rooftop solar system, we consider only those solar systems that are connected with the national grid via net metering. Below is a diagram showing how the rooftop system works.
First, solar panels generate DC current during sunny hours and go into the grid-tied solar inverter via DCDB. A solar inverter converts DC current to AC current and feeds into the national grid via ACDB and Net Meter.
How much does rooftop solar cost?
The cost of rooftop solar installation depends on capacity, technology, installation area, and brands. The average price of 1kW rooftop solar is Rs. 60,000, the average price of 2kW rooftop solar is Rs. 1,20,000, 3kW rooftop solar is Rs. 1,80,000, and the price of 5kW rooftop solar is Rs. 3,00,000. Below is the approximate price list of rooftop solar; you should refer:
| Capacity | Cost | Govt. Subsidy |
| 3kW | Rs. 1,80,000 | Rs. 78,000 |
| 5kW | Rs. 3,00,000 | Rs. 78,000 |
| 10kW | Rs. 5,00,000 | Rs. 78,000 |
What is a rooftop solar scheme?
Many consumers want to install solar rooftops, but they want some financial support from the government. Gujarat is the best example where the number of rooftop solar installations increased a lot after giving solar subsidies, solar loans, and easy net metering facilities. Our Prime Minister Narendra Modi has introduced a national portal, PM Surya Ghar, where electricity bill payers can apply for rooftop solar. In this scheme, the government has a target to install solar rooftops in 1 crore homes by 2027, and he will provide Rs. 30,000 to 78,000 in solar subsidies for up to 10 kW of installation.
Who is eligible for the rooftop solar scheme?
Before applying a rooftop solar scheme, you should know the following things:
- The solar subsidy is only available on grid-connected solar systems.
- The electricity connection should be residential only.
- A consumer must apply through a national portal.
- A solar installation must be authorised by vendors.

How to clean rooftop solar panels?
Cleaning is one of the most important factors in generating electricity because rooftop solar panels are installed in outdoor areas. Heavy dust and birds can result in a very thick layer of dust collecting over the solar panels. Thus, regular cleaning becomes essential to generate electricity, but how to clean it? Here are some important things you should know about this:
Do:
-
Clean solar panels using water, soft clothes, and a wiper.
-
The best time to clean is before sunrise or after the sun sets.
-
Try to shutdown from DCDB.
-
Always maintain proper distancing between electrical wiring and solar panels.
