Rooftop Solar Process in Chennai: Quote, Net Metering & Service

A rooftop system in Chennai needs less attention than people expect and more than zero. Dust and construction grit cut output by 5–8% within a few months, so panels want washing every six to eight weeks in the dry season. Coastal salt in Besant Nagar, Thiruvanmiyur and Kelambakkam is harder on mounting hardware than on the modules — that is why we specify extra corrosion treatment on structures within a few kilometres of the sea. Inverters are the component that actually fails, usually somewhere between year six and year ten.

Our workmanship warranty runs five years on structure, cabling, earthing and commissioning, alongside the manufacturer's 25-year panel performance warranty. We also take fault calls and annual maintenance contracts on systems other companies installed, which is often how people find us in the first place — the original installer stopped answering the phone. When choosing a solar company in Chennai, ask who will still be servicing the system in year eight.
