5 kW solar system price in 2026
A 5 kW on-grid rooftop system with DCR panels typically costs ₹3.25 lakh to ₹3.75 lakh fully installed in 2026. That covers 10 panels of 540 Wp, an on-grid inverter, the mounting structure, wiring, earthing, the net meter application and installation. After the ₹78,000 PM Surya Ghar subsidy you pay about ₹2.47 lakh to ₹2.97 lakh, or ₹49,400 to ₹59,400 per kW.
A 5 kW system gets the same ₹78,000 subsidy as a 3 kW one. Many DISCOMs need a three-phase connection or a sanctioned load of 5 kW or more at this size, so check your bill before you order.
