Approximately 8,000–10,000 square metres (about 85,000–100,000 sq ft) of shadow-free roof area is needed for 1 MW of rooftop solar, depending on module efficiency and layout.
Most industrial and commercial rooftop solar projects in India pay back in roughly 3–5 years, depending on your grid tariff, consumption profile and system cost — after which the plant produces power at near-zero marginal cost for the rest of its 25-year life.
Industrial rooftop systems are typically larger (hundreds of kW to multiple MW) and installed on factory or warehouse sheds, while commercial systems serve offices, malls, hospitals and institutions. Design considerations such as roof type, structural loading and consumption pattern differ between the two.
Rooftop solar projects require net-metering or captive-consumption approval from the DISCOM and electrical inspector (CEIG) clearance. As your EPC partner, Alpha Devraj manages the complete approval and liaison process.
