For businesses in Surat, commercial rooftop solar delivers compelling returns — typically 3–5 year payback with 40% accelerated depreciation tax benefit in Year 1 and GST input credit recovery. With commercial electricity tariffs at ₹8–₹17/unit in Gujarat, every unit of self-generated solar power represents significant savings.
Commercial systems range from 10 kW for small shops to 500 kW+ for factories. The right size depends on your rooftop area, sanctioned load, and daytime consumption pattern. A detailed energy audit is recommended before sizing.
Under Section 32 of the Income Tax Act, solar assets qualify for 40% accelerated depreciation in Year 1. For a ₹50 lakh investment at 30% tax rate, this saves ₹6 lakh in taxes in the first year alone. Combined with GST input credit, effective cost drops significantly.
Commercial solar can be financed via equipment loans (SBI Surya Shakti, PNB, HDFC Green Loans), RESCO/PPA model (zero capex), or operating lease. RESCO is increasingly popular for businesses that want solar without upfront investment.
