Room heaters and geysers consume a lot of electricity especially in winter. In many homes these appliances run for several hours a day. The result is that people get upset after seeing the bill at the end of the month. To avoid this increasing expense, a large number of people are now installing solar panels on the roof of their houses.

The Indian government is also encouraging people in this direction. Under the Prime Minister Surya Ghar Free Electricity Scheme, subsidy is being given for installing solar panels in homes. Its objective is that people should generate electricity themselves. Dependence on the grid should be reduced and monthly expenses would be reduced. But due to less sunlight in winter, questions arise in people’s minds.

Subsidy is also given by the Government of India under PM Suryaghar Yojana for installing solar panels in the house. Due to which people’s expenses for installing solar panels are significantly reduced. If you generate more electricity from this, you can also sell it.

If your target is 300 units every month. And if you do not know how many MW of solar panels should be installed for this, then let us tell you that generally 3 kW on-grid system is considered sufficient for this. 3 kW i.e. 0.003 MW.

A 1 kW system provides an average of 3–4 kWh per day in India. So a rating of 2.5–3 kW is capable of providing 300 kWh per month. However, it also depends on the weather and location. According to that, it could be more or less.

Under the Central Government’s PM Surya Ghar Yojana, the government wants to reduce people’s electricity bills to zero. Under the scheme, systems up to 1–3 kW are subsidized by the government. Therefore installation up to 3 kW is eligible under this scheme.

Because you are getting it installed on the flat. So first you have to look at the roof space. After this, pay attention to the number of panels. According to 330–400 W panels, approximately 8–10 panels are required for 3 kW. For this, the space required on the roof is usually 200–350 square feet.

The conditions of this scheme are different in many states. There may be different rules for group housing or apartments. Some DISCOMs have net-metering rules and levy minimum charges, so first know the policy of your local DISCOM. After this you can apply online.
