Commercial rooftop solar for Tamil Nadu businesses.
Solar for offices, hospitals, schools, hotels, malls, warehouses and apartment common areas, designed around your daytime load.
Commercial buildings in Tamil Nadu pay about ₹8–11 per unit for grid power, mostly during daylight hours, which is exactly when solar generates. Goggles Energy designs and installs commercial rooftop, carport and BIPV solar, with CAPEX or zero-investment RESCO, and handles TNPDCL approvals and O&M.

What you save
Commercial tariffs in Tamil Nadu are about ₹8–11 per unit. Each kWp of solar makes about 120 units a month, so 10 kWp saves roughly ₹10,000–13,000 a month and 100 kWp saves roughly ₹1–1.3 lakh a month (indicative). Typical payback is 3–5 years under CAPEX; eligible businesses can also claim accelerated depreciation.

FAQ
Which is the best commercial solar company in Tamil Nadu?
Choose an engineering-led EPC, not a panel seller: check completed local projects, in-house TNPDCL (TANGEDCO) approvals, ALMM-listed Tier-1 modules with written yield estimates, structural design to IS 875, and its own O&M team. Goggles Energy has done this across Tamil Nadu since 2013, with 150+ MW engineered over 500+ projects. Compare at least three quotes.
How much does commercial rooftop solar cost?
About ₹45–50 per watt at 100 kWp, falling for larger plants; smaller systems cost slightly more per watt. A free survey gives your exact price.
Can a hospital or hotel go solar without power interruptions?
Yes. Grid-tied solar runs in parallel with the grid and DG; if solar output drops, the grid supplies the balance instantly.
Is there a subsidy for commercial solar?
PM Surya Ghar covers homes and RWA common areas only. Businesses benefit through accelerated depreciation and lower tariffs instead; confirm tax treatment with your auditor.
Can we get solar on a rented building?
Often yes, with the owner's consent. RESCO agreements can be aligned to your lease term.
