Estimate your solar system cost, savings & PM Surya Ghar subsidy
Updated for 2026 rates and government subsidies
The cost of a rooftop solar panel system in India ranges from ₹55,000 to ₹60,000 per kW for residential and ₹45,000 to ₹50,000 per kW for commercial installations. A typical 3kW system costs around ₹1.5-1.8 lakhs, while a 5kW system costs around ₹2.5-3 lakhs. After PM Surya Ghar subsidy, the effective cost can be significantly lower.
Under the PM Surya Ghar Yojana, residential solar installations get: ₹78,000 for systems up to 3kW, and ₹78,000 + ₹30,000 per kW for systems between 3-10kW. For example, a 5kW system gets ₹78,000 + (2 × ₹30,000) = ₹1,38,000 as subsidy. Systems above 10kW don't qualify for residential subsidy.
The number of panels depends on your monthly electricity consumption and the panel capacity. A typical 540W panel generates about 4-5 units per day. For a home with ₹3,000 monthly bill (approximately 300 units), a 2-3kW system with 4-6 panels is usually sufficient.
The payback period for residential solar in India is typically 4-6 years, depending on your electricity bill, system size, and subsidy availed. With the PM Surya Ghar subsidy, you can reduce the payback period to 3-4 years.
A typical Indian household can save ₹36,000-60,000 per year on electricity bills with a solar system. Over 25 years, this amounts to ₹9-15 lakhs in savings, minus the initial investment.
