Why go solar

Why go solar

A rooftop system brings your EB bill down every month, for 25 years or more.

A much smaller EB bill

Most homes see the bill fall by 70 to 90%. A 3 kW system saves around ₹3,400 every two months.

Subsidy for homes

Houses can get up to ₹78,000 under PM Surya Ghar. We fill in the application for you.

Net metering

Units you do not use go back to the grid and are adjusted against your next EB bill.

Little upkeep

Wipe the dust off now and then and get the wiring and inverter checked once a year.

Worked example

An example with numbers

Take a home paying ₹4,000 every two months on the EB bill. With a 3 kW system the bill could come down to about ₹600, which is a saving of around ₹3,400 every two months, or about ₹20,400 a year.

The system costs ₹1,98,000 to ₹2,28,000 before subsidy. After the ₹78,000 PM Surya Ghar subsidy you pay ₹1,20,000 to ₹1,50,000, and it pays itself back in roughly 6 to 7 years.

These figures come from our savings calculator and are estimates. Your own numbers depend on your roof and how much power you use.

Payback by system size
