Rooftop Solar Cost in India: Benchmark Price and Net Cost After Subsidy

The Ministry fixed a benchmark cost of ₹50,000 per kW for the first 2 kW and ₹45,000 for the additional kW (from 13 February 2024). A 3 kW system is therefore benchmarked at ₹1,45,000; after the ₹78,000 subsidy that is ₹67,000. Real quotes vary with brand, roof and state.

Benchmark cost and cost after subsidy

Normal states, central subsidy only. State top-ups would reduce the net cost further.

2 kW₹1,00,000₹60,000₹40,000
3 kW₹1,45,000₹78,000₹67,000

How to use the benchmark

  • Get at least three written quotes for the same size, with panel make, inverter make and warranty stated.
  • Compare each total with the benchmark above. A quote far above it needs a reason, such as a difficult roof or longer cable run, in writing.
  • Do not judge on the subsidy alone: the number that matters is what stays in your pocket, quote minus subsidy. The calculator does this.
  • The Ministry also publishes indicative costs of components such as modules and inverters, so that consumers are not overcharged. Look for them on the portal.

What affects the real price

  • Module and inverter brand. Modules must still be domestic-content compliant to get the subsidy.
  • Your roof: height, shade, structure, and the distance to the meter.
  • Your state: special category states have a higher benchmark (₹55,000 and ₹49,500) and a higher subsidy.
  • Net meter: it is provided by the DISCOM, or you can buy one from an enlisted meter vendor, so ask whether the quote includes it.
  • Warranty and service: registered vendors must give free repair and maintenance for 5 years from commissioning.

It does not give market prices from installers; I have not sourced those, and they change. Use the benchmark as the official reference, then compare real quotes.

Common questions

What is a fair price for 3 kW rooftop solar in India?

The Ministry's benchmark is ₹1,45,000 for 3 kW (normal states). After the central subsidy of ₹78,000, the benchmark net cost is ₹67,000. A quote well above the benchmark deserves a written explanation.

Is the benchmark the price I will pay?

No. The benchmark is a reference the scheme uses; you agree the actual price directly with the vendor. It was set in February 2024 and can be revised, so check the current figure on the portal.
