How Solar Subsidy Calculation Works
System Cost Calculation
Total system cost = System size × 1000W × ₹67/W = 3 kW × 1000 × ₹67 = ₹2,01,000
Central Subsidy (PM Surya Ghar)
First 2 kW @ ₹30,000 + Next 1 kW @ ₹18,000 = ₹78,000
State Subsidy
Gujarat offers additional 12% subsidy capped at ₹30,000
Net Investment
Net cost = Total cost - Total subsidies = ₹2,01,000 - ₹1,02,120 = ₹98,880

Solar Subsidy Calculator - FAQs
How is the central subsidy under PM Surya Ghar Yojana calculated?
Residential systems get ₹30,000/kW for the first 2 kW, plus ₹18,000/kW for the next 1 kW (2-3 kW), capped at a maximum of ₹78,000 for systems of 3 kW and above.
Do commercial installations get the central subsidy?
No, the PM Surya Ghar Yojana central subsidy applies to residential customers only. Commercial installations may instead be eligible for accelerated depreciation tax benefits.
How is the state subsidy calculated?
We apply a state-specific percentage of the total system cost (for example, Gujarat around 12%, Delhi around 10%), capped at ₹30,000, and only for residential customers in this calculator.
Do subsidy amounts and rates change over time?
Yes — central and state subsidy schemes, rates and caps are revised periodically by the government, so the figures here are estimates. Always verify current rates on the official PM Surya Ghar portal or your state renewable energy department before budgeting.
What documents are typically needed to apply for the subsidy?
Common requirements include identity and address proof, bank account details for the subsidy transfer, and a solar system quotation from an empaneled vendor, though exact requirements vary by state.
