Rooftop Solar for Indian Factories — Key Facts
India receives some of the highest solar irradiation in the world — Gujarat, Rajasthan and Maharashtra average 5–6 peak sun hours per day year-round. A 100 kWp rooftop system typically generates 130,000–160,000 kWh per year. At ₹8/kWh, this represents ₹10–13 lakh/year in savings with typical system cost of ₹35–45 lakh — giving a payback of 3–5 years.
Net Metering in India
Most state DISCOMs now offer net metering for industrial consumers up to 1 MW. Excess solar generation is exported to the grid and credited against your electricity bill at a fixed rate (typically ₹3–5/kWh). Check with your local DISCOM for the current net metering rate and application process.
