What is On-Grid Residential Solar?
On-grid (grid-tied) solar is the most popular rooftop system for Tamil Nadu homes. Solar panels on your roof generate DC power; an inverter converts it to AC and feeds it directly into your home wiring. Any excess power flows back to the TANGEDCO grid through a bidirectional (net) meter, and you earn unit credits that offset night-time consumption. There are no batteries — which keeps cost low and maintenance minimal. Most 3 kW residential systems offset ₹3,500–₹4,500 of monthly billing and qualify for the central PM Surya Ghar subsidy of up to ₹78,000. Payback typically lands in the 3–4 year range, and panels carry a 25-year performance warranty. We handle the design, DISCOM application, installation and post-commissioning paperwork end-to-end.
