How do I choose a solar company in Chennai?

Compare authorisation for the panel brand, whether equipment is ALMM-listed, an itemised quote, a site survey before pricing, written workmanship terms, who files the subsidy and net-metering paperwork, and whether after-sales service is local.

Is GenSolar Energy an authorised dealer?

GenSolar Energy is an authorised Tata Solar dealer (Tata Power Solaroof). Waaree, Adani, Vikram, Luminous and AM Solar products are supplied through our wholesale and dealer channel.

What should a solar quotation in Chennai include?

Panel make and wattage, inverter model, structure type and height, cabling, earthing and lightning protection, net-metering charges and the warranty terms — each listed separately rather than as one lump sum.

How long does the subsidy and net-metering process take?

Installation of a typical home system is usually one working day. Approval, inspection and net-meter timelines vary by application, section office and utility workload, so we do not promise fixed dates.

What to compare between solar companies

System design

Sizing should come from your actual monthly units, roof area and shading — not a standard package. Ask how the size was calculated.

Panel and inverter quality

Check the module brand, wattage and whether it is ALMM-listed (required for subsidy), plus the inverter make and its warranty.

Authorised supply

Authorised dealers supply serial-verified panels with the manufacturer's warranty registered in your name. GenSolar is an authorised Tata Solar dealer.

Installation standards

Ask about structure material and height, earthing, lightning protection and cable routing. Elevated structures keep a terrace usable.

Written warranty terms

Manufacturer warranties cover panels and inverters; the installer's workmanship cover should be in writing. Ours is a five-year installation support agreement.

Subsidy and net-metering help

Find out who files the PM Surya Ghar application and the TNPDCL (TANGEDCO / TNEB) net-metering paperwork, and who follows it up.

After-sales service

Panels last decades. Check that the company can visit for faults and cleaning, and whether it services systems installed by others.

Transparent quotation

A good quote lists panels, inverter, structure, cabling, earthing and net-metering separately, after a site survey.
