How it is calculated
There is no official market price list for solar panels. MNRE does publish a benchmark cost for PM Surya Ghar, which it uses to set the subsidy. This page prices your system at that benchmark (or your own quote), then subtracts the central subsidy.
Benchmark price = min(kW, 2) × ₹50,000 + max(0, kW − 2) × ₹45,000 · Net = price − subsidy (₹30,000/kW first 2 kW + ₹18,000 third kW)
Price the first 2 kW
The MNRE benchmark is ₹50,000 per kW for the first 2 kW (₹55,000 in special category states). So 2 kW is ₹1,00,000 at the benchmark.
Add each extra kW
Each kW after the second is ₹45,000 (₹49,500 in special category states). A 3 kW system is ₹1,45,000; this page applies the same rate to 5 kW and 10 kW systems.
Subtract the central subsidy
₹30,000 per kW for the first 2 kW and ₹18,000 for the third, capped at ₹78,000. A 3 kW system at the benchmark costs ₹67,000 after the subsidy.
Solar system price at the MNRE benchmark (general states)
| System size | Benchmark price | Central subsidy | Price after subsidy |
|---|---|---|---|
| 1 kW | ₹50,000 | ₹30,000 | ₹20,000 |
| 2 kW | ₹1,00,000 | ₹60,000 | ₹40,000 |
| 3 kW | ₹1,45,000 | ₹78,000 | ₹67,000 |
| 5 kW (estimate) | ₹2,35,000 | ₹78,000 | ₹1,57,000 |
| 10 kW (estimate) | ₹4,60,000 | ₹78,000 | ₹3,82,000 |
What most pages get wrong
The only official price is the MNRE benchmark
MNRE fixes a benchmark cost per kW to work out the subsidy. Vendors charge a mutually agreed price, and the indicative component costs the guidelines say MNRE will publish (§6(g)) have not been published.
The subsidy stops growing at 3 kW
The central subsidy peaks at ₹78,000 in general states and ₹85,800 in special category states. Beyond 3 kW it no longer grows, so the price after subsidy climbs at the full per-kW cost.
DCR modules and a registered vendor
To get the subsidy, modules must meet the Domestic Content Requirement and the vendor must be registered on the PM Surya Ghar portal.
Five years of free maintenance
Registered vendors must repair and maintain the system free for a 5-year Comprehensive Maintenance Contract period from commissioning.
