Rooftop Solar Prices in India for 3 kW, 5 kW and 10 kW Systems in 2026
Estimated 2026 installed prices for standard grid-connected residential solar in India are ₹1.65–2.10 lakh for 3 kW, ₹2.55–3.20 lakh for 5 kW, and ₹4.80–5.90 lakh for 10 kW before subsidy. Eligible homes can receive up to ₹78,000, with the standard central support capped at 3 kW. Final economics vary by consumption, state tariffs, roof conditions, and export credits.
Under PM Surya Ghar, central assistance for general-category homes tops out at ₹78,000 once system size reaches 3 kW. A 5 kW or 10 kW installation therefore does not unlock a larger standard central amount, though special-category states and UTs can have separate rates and state-level incentives may add support.
The subsidy is usually released after installation, inspection and commissioning approvals, so buyers should not automatically expect the vendor to subtract it from the upfront bill. Output estimates of 100–140 units per kW monthly translate into roughly 300–420 units for 3 kW, 500–700 for 5 kW, and 1,000–1,400 for 10 kW, depending on site conditions.
Households with suitable roofs and daytime electricity use could see lower bills, while high upfront costs and subsidy timing may limit uptake among budget-constrained families. Because savings depend on state tariffs, consumption patterns and export credits, the scheme’s household impact may vary widely; installers and local suppliers could also see demand shift as more homes evaluate rooftop systems.
