Solar Panel Installation in Chennai
End-to-end solar power in Chennai — survey, design, subsidy, net metering and installation by an authorised Tata Solar dealer.
GenSolar Energy handles solar panel installation in Chennai end to end — free rooftop survey, system design, PM Surya Ghar subsidy filing, TANGEDCO net metering, installation in 3–5 days and 25-year warranty registration.
Chennai receives about 5.8 hours of usable sunlight a day, among the best in Tamil Nadu, so every kilowatt installed on a city rooftop generates roughly 120 units a month. For a typical household running two ACs and a pump, a 3 kW system covers almost the whole bill. Larger villas, clinics and small factories move to 5 kW–10 kW and beyond.
As a solar installation company in Chennai we work with genuine Tata Power Solar modules as the default, with Waaree, Adani and Vikram available on request. Every panel is ALMM-listed and MNRE-approved, which is what keeps your subsidy claim valid.
GenSolar Energy is an authorised Tata Solar dealer and rooftop solar installation company serving Chennai, Tiruvallur, Kancheepuram, Vellore, Chengalpattu and Viluppuram, with 500+ installations, MNRE approval and a 25-year warranty.
How solar panel installation in Chennai works
1. Free site survey
Our Chennai engineer measures usable roof area, runs shadow analysis across the day, checks the RCC slab or sheet structure and reads your last TANGEDCO bill to size the system.
2. Design, quote & subsidy filing
You get an itemised design — panel count, inverter model, structure gauge, cable route. We then file the PM Surya Ghar application on the National Portal and start TANGEDCO net-metering approval.
3. Installation in 3–5 days
Mounting structure, panel laying, DC/AC cabling, earthing and lightning arrestor, inverter mounting and ACDB/DCDB wiring — done by our own crew, not subcontracted labour.
4. Net meter & commissioning
TANGEDCO installs the bi-directional meter, we commission the system, hand over the monitoring app and register your 25-year panel warranty in your name.
Which system size suits your Chennai home?
Sizing is driven by your monthly TANGEDCO units, not by roof size alone. A 1 kW system needs about 70 sq ft of shade-free roof and produces ~120 units a month; 3 kW needs ~200 sq ft and produces ~360 units. Apartments usually start with a common-area system for lifts, pumps and corridor lighting, while independent houses in Ambattur, Velachery, Anna Nagar and Tambaram normally land on 3 kW–5 kW.
On-grid, hybrid or off-grid?
On-grid is the cheapest and the only configuration eligible for full net metering — right for most of central Chennai. Hybrid adds a lithium battery and keeps essentials running through outages, which is worth it on the Avadi–Tiruvallur corridor. Off-grid is reserved for farms and sites without a reliable TANGEDCO connection.
