Guides

Read this before you sign a solar quote

Eight short guides covering everything a homeowner needs: how the ₹78,000 subsidy actually reaches your account, what net metering does to your bill, and what each system size honestly powers. No jargon, no selling.

• 01

  PM Surya Ghar subsidy: rates, eligibility and amounts

  The PM Surya Ghar Muft Bijli Yojana gives residential households a central subsidy of ₹30,000 per kW for the first 2 kW of rooftop solar, plus ₹18,000 for the 3rd kW — a maximum of ₹78,000 for systems of 3 kW or larger. The amount is credited directly to your bank account after your DISCOM inspects the installation.

  How to apply for the PM Surya Ghar subsidy, step by step

  Applying for the rooftop solar subsidy takes four stages: register on the PM Surya Ghar national portal with your electricity connection and bank details, get DISCOM feasibility approval, have a registered vendor install the system, and receive inspection and commissioning — after which the subsidy lands in your bank account, usually within 30 days.

• 03

  Net metering, explained like a bill

  Net metering means your exported solar units offset the grid units you consume. A bidirectional meter records both flows, your DISCOM bills the net difference, and surplus exports carry forward as credit. This is why a solar home can bring its bill near zero even though panels produce nothing at night.
