What to look for in a solar company in Chennai
An honest checklist — use it on us and on every other quote you collect.
Is the company an authorised dealer?
Authorised dealers supply serial-verified panels with the manufacturer's warranty registered in your name. Grey-market stock often has no valid claim path. GenSolar is an authorised Tata Solar dealer.
How many installations have they completed?
Ask for a count and for local references you can call. GenSolar has completed 500+ rooftop installations across Chennai and five neighbouring districts.
Do they use MNRE-approved equipment?
Subsidy claims are rejected if panels or inverters are outside the ALMM/MNRE approved list. Every component we install is on the approved list.
Who files the PM Surya Ghar subsidy?
A good company files the National Portal application and TANGEDCO net-metering paperwork for you, and tracks disbursement. We do both at no extra charge.
What warranties are in writing?
Expect 25 years linear performance on panels, 10 years on the inverter, and a separate workmanship warranty. Ours is 5 years workmanship with AMC.
Is there local after-sales service?
Panels last 25 years; the company servicing them should be local. Our engineers are based in Chennai with quarterly cleaning and remote monitoring.
Is the quote itemised?
A trustworthy quote lists panels, inverter, structure, cabling, earthing, and net-metering separately. Beware of a single lump-sum number.
Do they survey before quoting?
Shadow analysis and a structural check should happen before any price is committed. Our site survey is free and non-obligatory.
