How Our Solar Calculation Works

Solar Generation Benchmark

In North & Central India, a 1 kWp Tier-1 Mono PERC / TopCon solar plant generates an average of 4.2 to 4.5 units (kWh) per day, resulting in approximately 120 to 135 units per month and ~1,500 units annually.

PM Surya Ghar Subsidy Slabs

Central Government direct subsidy is fixed at ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW and above for residential connections. Subsidies are credited directly via DBT to your bank account.

25-Year Lifetime Returns

Calculations assume a standard 0.55% annual panel linear degradation rate and an average 3% annual grid tariff inflation, making your long-term returns significantly higher than initial estimates.
