How Much Does a 3kW Solar System Cost?
A 3kW rooftop solar system typically costs between ₹1,80,000 to ₹2,40,000 depending on the panel brand, inverter type, mounting structure, and installation complexity. Prices may vary based on location, roof type, and vendor. Government subsidy can significantly reduce the upfront cost for residential customers.
Government Subsidy for 3kW Solar Systems
Under the PM Surya Ghar Yojana, residential customers in Delhi may be eligible for subsidy on rooftop solar systems. For a 3kW system, the subsidy can be up to ₹78,000. The exact amount depends on current government guidelines, system capacity, and eligibility criteria. Y2 Solar helps customers understand the documentation and process.
Roof Space Required
A 3kW solar system generally requires around 250 to 300 sq ft of shadow-free rooftop area. The exact space depends on panel wattage — higher wattage panels need less area. Your roof should receive direct sunlight for at least 4–5 hours daily for optimal generation.
Expected Monthly Generation
In Delhi, a 3kW solar system can generate approximately 350 to 420 units (kWh) per month depending on sunlight, weather, panel tilt, and seasonal variation. This generation is usually sufficient to offset a significant portion of a typical household electricity bill.
Electricity Bill Savings
With net metering, excess solar electricity is exported to the grid and adjusted against your bill. A well-sized 3kW system can help save ₹2,000 to ₹3,500 per month on electricity bills. Actual savings depend on your consumption pattern, tariff slab, and system performance.
