Rooftop solar, answered

The central government gives ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, so ₹30,000 for 1 kW, ₹60,000 for 2 kW and a maximum of ₹78,000 for 3 kW or more, in Odisha and West Bengal alike. In Odisha, eligible domestic consumers can also get the state subsidy of up to ₹60,000 while the state quota lasts. The subsidy is paid directly into your bank account after the system is commissioned.

Yes. Along with Odisha, we now install across West Bengal: Kolkata, Howrah, Hooghly, North and South 24 Parganas, and Purba and Paschim Medinipur, including Digha, Contai, Haldia, Tamluk, Kharagpur and Midnapore. The full PM Surya Ghar central subsidy applies, and we handle the application and net metering with WBSEDCL, or CESC in and around Kolkata.

Any Indian household with its own house, a roof suitable for solar panels and a valid domestic electricity connection, which has not already taken another subsidy for rooftop solar. Housing societies and RWAs can claim ₹18,000 per kW for common facilities such as lifts, pumps and lighting.

Usually your latest electricity bill (for the consumer number), Aadhaar, a mobile number and email linked to the application, and your bank details with a cancelled cheque or passbook copy. We check your documents during the site survey and fill in the application on the national portal with you.

Yes. Public sector banks offer collateral-free loans at concessional interest for residential systems under PM Surya Ghar. We help you prepare the quotation and documents the bank asks for.

About 100 sq ft of shadow-free roof for every kW. A 3 kW system, enough for most homes, needs around 300 sq ft. RCC flat roofs, tin sheds and sloped roofs can all be used with the right mounting structure.

Fitting the panels takes one to three days. The whole journey, including DISCOM approval, the net meter and commissioning, usually takes three to six weeks, depending mostly on your DISCOM.

Your DISCOM replaces the meter with a bi-directional net meter. Units your panels export to the grid are subtracted from the units you draw, and you pay only for the difference. We file and follow up the net-metering application for you.

A standard on-grid system switches off when the grid fails, a safety rule that protects line workers. If you need power during outages, ask us about a hybrid system with battery backup.

In Odisha and West Bengal each kW of panels produces about 4 units a day on average, around 120 units a month. A 3 kW system therefore makes about 360 units a month, more in summer and less during the monsoon.

For most homes that use the subsidy, the system pays for itself in three to five years through lower bills, and keeps saving for 25 years or more. Use our savings calculator for an estimate on your own bill.

Very little: rinse the panels with plain water every two to three weeks to remove dust, and have the system checked once a year. Systems installed under PM Surya Ghar include five years of maintenance from the installer, and we offer an AMC after that.

Solar panels carry the manufacturer's performance warranty, normally 25 years, and the inverter carries its manufacturer's warranty. Our own workmanship warranty is written into every quotation.
