PM Surya Ghar central subsidy

Under the PM Surya Ghar: Muft Bijli Yojana for residential rooftop solar, the central financial assistance is ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 for systems of 3 kW and above. The calculator applies this automatically.

How much power will it generate?

In Odisha, a well-installed 1 kW system typically produces about 3.5–4.5 units a day depending on season and shade. A 3 kW system can therefore generate roughly 360 units a month, enough for many households.

Steps to apply

  1. Register on the national rooftop solar portal with your electricity consumer number.
  2. Choose a registered vendor and get the feasibility approval from your DISCOM.
  3. After installation and net-meter fitting, submit the commissioning details.
  4. The subsidy is credited to your bank account.

Subsidy rules can change. Verify current amounts on the official portal before deciding.
