Solar Rooftop Subsidy & Savings Calculator (PM Surya Ghar)

Formula & Calculation Methodology

Net Cost = Gross System Cost - PM Surya Ghar Subsidy; Monthly Savings = Capacity (kW) × 120 Units × Avg Grid Tariff.

Step-by-Step Worked Example

System: 3 kW Solar | Monthly Bill: ₹3,500 | Benchmark Cost: ₹1,80,000

1. Gross 3kW System Cost = ₹1,80,000
2. PM Surya Ghar Central Subsidy = ₹78,000 (Direct DBT)
3. Net Out-of-Pocket Customer Cost = ₹1,02,000
4. Monthly Power Generation = 360 Units (Saves ~₹2,700/mo)
5. Estimated Payback Period = 3.1 Years (Free Electricity for next 22+ years)

PM Surya Ghar: Muft Bijli Yojana Subsidy Structure (2024-2026)

Under the PM Surya Ghar scheme, residential households receive direct benefit transfer (DBT) subsidy: ₹30,000 for 1 kW systems, ₹60,000 for 2 kW systems, and ₹78,000 for 3 kW and higher systems.

Surplus electricity produced by rooftop panels is fed back into the state grid via bi-directional Net Metering.
