What is Commercial Rooftop Solar (Offices, Showrooms)?
Commercial rooftop solar slashes your monthly TANGEDCO bill by 50–70% and doubles as a tax-saving asset. A 25 kW office system generates ~36,000 units/year and typically pays back in under 5 years and producing free electricity for the next 20+. On the tax side, businesses can claim 40% Accelerated Depreciation in Year 1 (under Section 32) plus full GST input credit on the installation. Net-metering exports excess weekend & holiday generation back to TANGEDCO for credits. We design HT/LT-compatible systems with branded panels, IGBT inverters, lightning protection, remote monitoring and ESG-grade reporting for your sustainability disclosures.
