Solar questions, answered.

A residential rooftop system costs roughly ₹55,000–₹75,000 per kW installed before subsidy (indicative 2026). So a typical 3 kW system is about ₹1.6–2.2 lakh before the PM Surya Ghar subsidy, and far less after it.

A well-sized, net-metered system can cut your bill by around 70% or more. Roughly 1 kW generates ~4 units a day, and every unit you generate is a unit you don’t buy from the grid.

For a subsidised residential system, payback is usually 3–4 years. After that, the power is effectively free for the panels’ ~25-year life.

Yes. Labour, structure and transport differ by city, and sunlight varies by region, so quotes for the same size can differ. Always compare 3 local quotes.

₹30,000 per kW for the first 2 kW plus ₹18,000 for the 3rd kW, capped at ₹78,000 for a 3 kW-or-larger residential system.

New registrations on the national portal closed on 6 June 2026. If you registered before then, your application is valid — track its status and installation. Watch for any future intake.

It’s for residential rooftop only, the panels must be ALMM-listed with DCR (domestic) cells, and the system must be installed by a registered vendor and connected with net metering.

It’s credited to your bank account after installation, inspection and net-meter setup — officially within 30 days, in practice often 45–60 days.

Net metering lets your system export surplus daytime power to the grid and draw power back at night, so you’re billed only for your net usage. It’s what makes solar wipe out most of your bill.

Net metering is deemed feasible up to 10 kW for homes under the Electricity (Rights of Consumers) Rules, 2020. You apply through your DISCOM after installation.

Usually 15–45 days after installation, depending on your state and DISCOM. A good installer handles the application for you.

Usually no. On a grid-tied, net-metered system the grid acts like a free battery. Add storage only if you need backup during outages.

Pick a registered vendor with in-house (not sub-contracted) installation, ALMM panels, a written warranty on workmanship, and real local references. Compare at least 3 quotes.

Sky-high “MRP then discount” pricing, no written warranty, pressure to pay fully upfront, non-ALMM panels, and no help with subsidy or net-metering paperwork.

Yes. It’s free and no-obligation. We share your details only with the vetted installers you’re matched to, and never spam you.

Very little. Mainly cleaning the panels of dust every couple of weeks in dry seasons, and an occasional check of the inverter and wiring. Many owners take a low-cost annual maintenance contract (AMC).

Panels typically carry a ~25-year performance warranty and a ~10–12-year product warranty. Inverters usually last 5–10 years and may be replaced once in the system’s life.

Dust can cut output noticeably, so regular cleaning matters. Rain actually helps by washing panels. Cloudy monsoon days produce less, but the yearly average still works out well.
