What a rooftop solar system costs, how PM Surya Ghar CFA, net metering, GST, DCR modules and solar loans work in 2026.
The price a vendor quotes for a rooftop solar system is only the starting point. What you actually pay, and how fast you get it back, depends on a set of rules that sit around the hardware: the central financial assistance (CFA) under PM Surya Ghar: Muft Bijli Yojana, any state top-up, the net metering or gross metering arrangement your DISCOM offers under the Electricity (Rights of Consumers) Rules, 2020 and your State Electricity Regulatory Commission's regulations, the GST rate on solar power generating systems, which fell from 12% to 5% from 22 September 2025, and the Domestic Content Requirement (DCR) that decides whether your modules qualify for subsidy at all.
This section explains each of those pieces and how they change the numbers. Start with the pillar guide, rooftop solar cost and payback in India, then go deeper into the PM Surya Ghar subsidy, the portal application steps, net versus gross metering, GST on solar, DCR, ALMM and BIS and solar loans.
