AI SummaryChief Minister s Solar Rooftop Capital Incentive Scheme is a Tamil Nadu government scheme that gives a capital subsidy of ₹ 20,000 per kilowatt for grid-connected domestic solar PV systems. It helps individual homeowners and flat owners move to renewable energy and cut their electricity bills.
In the Tamil Nadu Revised Budget 2026-27 presented on 5 August 2026, the state also announced a new Rooftop Solar Subsidy Scheme of up to ₹ 1 lakh per home in convergence with the central PM Surya Ghar Muft Bijli Yojana. The detailed guidelines for this new state top-up have not been notified yet, so the older capital incentive scheme continues to guide existing installations.
Chief Minister s Solar Rooftop Capital Incentive Scheme - Introduction
Chief Minister s Solar Rooftop Capital Incentive Scheme acts as a support system provided by the government to help homeowners switch to green energy. The scheme provides a capital subsidy of ₹ 20,000 per kilowatt for grid-connected domestic solar PV systems, which sits on top of the existing 30% subsidy offered by the Ministry of New and Renewable Energy (MNRE).
This scheme suits individual house owners and residential groups looking to install solar power. For individual homes, a 1 kW system can be applied for. For those living in residential flats, the scheme allows joining with others to apply for common usage systems with capacities of 5 kW, 10 kW, or higher multiples.
Installing a grid-connected system reduces electricity bills through net metering. For example, if a consumer uses 1,000 units from the grid but exports 600 units back from solar panels, only the net 400 units are paid for. These systems do not need expensive batteries, which waste about 15 to 20% of stored energy, so they are easier to maintain and do not require complex load segregation at home.
