Kerala’s rooftop solar sector is expanding rapidly as households, businesses and institutions look for ways to reduce electricity expenses and make greater use of renewable energy. The momentum has also been supported by government programmes such as PM Surya Ghar, which has encouraged more residential consumers to consider rooftop systems.
For consumers, choosing a solar company is no longer simply about comparing the price of panels. System design, installation quality, inverter selection, KSEB procedures, subsidy assistance, warranty coverage and after-sales service can all influence the value of a solar investment over its lifetime.
1. Tata Power Solar
Tata Power Solar is among the most recognisable names in India’s solar industry and has developed a substantial rooftop presence in Kerala. In August 2026, Tata Power Solaroof announced that it had crossed 61,000 rooftop solar installations in Kerala, with cumulative capacity exceeding 273 MWp. The company attributed much of the residential momentum to the PM Surya Ghar programme and its incentives for rooftop solar adoption.
For customers who place importance on an established national brand, extensive installation experience and structured after-sales support, Tata Power Solar remains an option worth evaluating.
