Commercial Solar Cost in India — 2026 Guide
Complete, transparent breakdown of commercial solar cost — from 3 kW small shops to 5 MW industrial plants.
Commercial Solar Cost — Quick Answer
Commercial solar cost in India in 2026 averages ₹20–50 per watt, all-inclusive. This includes solar panels, inverter, mounting structure, wiring, safety equipment, installation labour, and DISCOM net metering application charges.
Simple formula: Required System Size (kW) × 1,000 × ₹35 = Approximate Commercial Solar Cost
Example: 50 kW system = 50 × 1,000 × ₹35 = ~₹17.5 lakh
Larger systems (above 100 kW) attract lower commercial solar cost per watt due to economies of scale — expect ₹20–28/watt for 100 kW and above.
