How rooftop solar pays for itself

Three things decide whether solar is worth it for you.

Solar isn't automatically a good deal for everyone. Whether it pays off comes down to a few simple factors — here's the plain-English version.

01

Your bill is the fuel

The more electricity you use at a high tariff, the more solar offsets every month. A ₹500 bill rarely justifies the cost; a ₹3,000+ bill usually does. Solar replaces units you'd buy from the grid.

02

The subsidy cuts the cost

Under PM Surya Ghar, residential systems get a central subsidy up to ₹78,000 — which directly shortens payback. See how it works →

03

Then it runs ~25 years

Panels usually carry ~25-year performance warranties. Once the system pays for itself — often within several years — most of what it generates after that is money you keep.
