Find out how much you can save with rooftop solar. Enter your electricity bill details below.
Rooftop solar systems generate electricity from sunlight using photovoltaic panels installed on your roof. The electricity generated offsets your grid consumption, reducing your electricity bill. Under net metering, excess power is exported to the grid and credited to your account.
The Indian government offers significant subsidies for residential rooftop solar under the PM Surya Ghar Muft Bijli Yojana:
The subsidy is credited directly to your bank account after installation and inspection. Most households achieve payback in 4-6 years, after which electricity is essentially free for the remaining 20+ years of panel life.
If your area has frequent power cuts (3+ times per month), a solar system with battery backup eliminates both your bill AND power cut problems simultaneously. A regular inverter only provides backup during outages but doesn't reduce your bill.

How many units does a 3kW system generate?
A 3kW system generates approximately 12-15 units per day (360-450 units/month) in most Indian cities.
Do I need batteries?
Not necessarily. With net metering, excess power goes to the grid. But batteries help during power cuts and nighttime usage.
What about maintenance?
Solar panels require minimal maintenance — occasional cleaning (once a month) and annual inverter checkups. Most panels come with 25-year warranties.
Can I install solar on a rented house?
Technically yes, but you need landlord permission and the subsidy goes to the property owner. Portable solar systems are an alternative.
