Solar Panel Installation in Chennai
GenSolar Energy is a solar company in Chennai installing rooftop solar across the city — from Ambattur, Avadi and Anna Nagar to Velachery, Tambaram, Porur and Sholinganallur. As an authorised Tata Solar panel dealer in Chennai we handle the whole job in-house: site survey and shadow study, system design, solar panel Chennai supply, mounting structure rated for coastal wind loads, TANGEDCO net metering and the PM Surya Ghar subsidy filing. A typical residential solar Chennai system of 3 kW generates roughly 360–420 units a month, which clears the bill for most homes.
If you are comparing solar installation Chennai quotes or looking for the best solar panel dealer in Chennai, ask every vendor three things: is the module ALMM-listed, who files the subsidy paperwork, and who answers the phone in year seven. Solar power Chennai only pays back when the installer is still around to service it — our engineers are based here, and our workmanship warranty runs five years alongside the 25-year panel warranty.
