Coimbatore · Tamil Nadu
Independent advice for domestic TANGEDCO connections in the Manchester of South India. Rain-shadow sun helps yield versus coastal Chennai; free-unit tariff slabs still decide real savings after central CFA.
Coimbatore’s textile and pump-motor economy drives heavy daytime loads — borewells, AC, and workshop equipment. The Western Ghats block some monsoon cloud from the west, giving Coimbatore a drier profile than Chennai’s coast. Still, your TANGEDCO slab bill decides payback, not a generic TN average. Sealix advises; we are not TANGEDCO and not your installer. Start with the free home check.
PM Surya Ghar residential CFA is commonly ₹30,000 (1 kW), ₹60,000 (2 kW), and up to ₹78,000 for eligible 3 kW+ systems, paid as DBT after commissioning via pmsuryaghar.gov.in with your TANGEDCO service connection. Details: PM Surya Ghar guide.
Tamil Nadu has announced a rooftop solar subsidy scheme in convergence with PM Surya Ghar, with press coverage describing a combined household ceiling around ₹1 lakh. Detailed state guidelines (exact share, eligibility, process) may still be rolling out. Model your decision on central CFA first; treat state top-up as upside until TEDA / TANGEDCO / portal wording confirms it.
Grid-tied rooftop in Coimbatore needs TANGEDCO feasibility and net metering through the Coimbatore / Erode circle. Timelines vary by subdivision. Empanelled vendors and ALMM / DCR-eligible equipment still apply for CFA.
Palakkad Gap wind can stress mounting on exposed terraces in Peelamedu and Saravanampatti — installer engineering matters; websites cannot certify wind loads.
Coimbatore receives less annual rainfall than Chennai or Kochi, but October–November northeast monsoon still trims yield for weeks. March–May dry heat drives excellent generation — and heavy AC demand that solar partially offsets.
Textile-unit dust in Singanallur and Ganapathy industrial belts adds soiling. Size from annual bill units, not a summer-only estimate.
Independent houses in RS Puram, Race Course, and Vadavalli often have clear RCC terraces. Apartment societies on shared roofs in Saibaba Colony and Gandhipuram usually need society NOC — often the longest calendar item.
Many mid-bill Coimbatore homes land near 3 kW to capture the full central CFA ceiling. Going to 5 kW adds capacity with no extra central CFA — see 3 kW vs 5 kW, Chennai, and net metering in India.
