How we calculate
1 kW needs about 100 sq. ft (10 m²) of shadow-free roof and generates 3.7–4.6 units/day depending on your state.
Residential subsidy per PM Surya Ghar: ₹30,000/kW up to 2 kW + ₹18,000 for the 3rd kW, capped at ₹78,000. No central subsidy for commercial or industrial systems.
System cost uses typical turnkey rates for standard installations; the exact price depends on your site, structure and components chosen.
Savings assume today's tariff with no escalation over a 25-year panel life. CO₂ savings use 0.82 kg/kWh (India grid average).
