Rooftop Solar That Makes Your Electricity Almost Free

Rooftop solar is a photovoltaic system installed on the roof of your home, office or factory that converts sunlight into electricity — reducing your bill and carbon footprint.

The Central Government provides up to ₹78,000 subsidy for residential systems up to 3 kW. State subsidies may also apply.

Roughly 100 sq. ft. per 1 kW. A typical 3 kW home system needs about 300 sq. ft. of shadow-free roof.

The timeline depends on the survey, system size, roof readiness, equipment availability and the applicable approval process. Solaroof confirms a project-specific schedule after assessment.

Net metering lets you export surplus solar energy back to the grid and adjust it against your consumption — you only pay for the net units used.

Solar panels carry 25-year performance warranty. Inverters typically have 5–10 year warranties, extendable up to 25 years.

Maintenance requirements and available service scope are confirmed in the site-specific proposal.

PM Surya Ghar support is intended for eligible residential consumers. Commercial tax treatment should be confirmed with a qualified tax adviser.

Solar continues to generate at reduced output. Grid-tied systems automatically draw from the grid when needed.

Solar finance may be available from participating lenders. Eligibility, rates and tenure depend on the lender and applicant.

Payback depends on system price, generation, tariff, self-consumption and maintenance. Use the calculator for an indicative estimate, then request a site-specific proposal.
