PM Surya Ghar: Muft Bijli Yojana is the central scheme that makes residential rooftop solar dramatically cheaper. The subsidy is paid per kilowatt of installed capacity: roughly Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the third - capping out around Rs 78,000 for systems of 3 kW and above.
The flow is simpler than most people expect: register on the official pmsuryaghar.gov.in portal, choose an empanelled vendor, install, and the DISCOM inspects and commissions with net metering. The subsidy lands directly in your bank account after commissioning.
Two practical tips. First, only residential consumers qualify - and the vendor must be empanelled, so confirm before signing anything. Second, subsidy amounts and rules get revised; treat the figures here as indicative and verify on the portal before you commit.
