Privacy and limits
An estimate, not a quote. Real generation depends on your city, shade and roof angle; net-metering rules, fixed charges and the subsidy amount can change, so check pmsuryaghar.gov.in. Loan interest, inverter replacement and taxes are not included. Nothing you enter leaves your device.
