The Tamil Nadu Government, through the Energy Department, has officially released G.O. (Ms) No. 102 dated 19.09.2026, announcing the State Rooftop Solar Subsidy Scheme. Under this scheme, consumers receive Rs.5,000 (1kW), Rs.10,000 (2kW), or Rs.22,000 (3kW and above) as additional state subsidy directly credited to their bank account over and above the central PM Surya Ghar: Muft Bijli Yojana subsidy.

What is the Tamil Nadu State Rooftop Solar Subsidy Scheme?

The State Rooftop Solar Subsidy Scheme is a Tamil Nadu Government initiative implemented by TEDA (Tamil Nadu Energy Development Agency) in coordination with TNGECL (Tamil Nadu Green Energy Corporation Limited). The scheme complements the central PM Surya Ghar portal-based subsidy by providing an additional state top-up subsidy directly into the beneficiary's bank account.

The total budget allocated for this scheme is approximately Rs.50 Crore, ensuring financial support for the first one lakh eligible applicants across Tamil Nadu. This is a major step in the Tamil Nadu solar subsidy scheme for 2026, making the state one of the first to offer a dedicated top-up over the central subsidy.

Additional State Subsidy Amount: Full Breakdown

The TN solar subsidy under G.O. 102 is over and above the PM Surya Ghar central subsidy. Here is the complete breakdown:

1 kW System — Rs.5,000 State Subsidy

Consumers who install a 1 kW rooftop solar system and register on the PM Surya Ghar portal on or after 05.08.2026 are eligible to receive an additional Rs.5,000 from the Tamil Nadu state government. This is in addition to the central subsidy of Rs.30,000 for 1 kW systems. Learn more: 1kW On-Grid Solar System in Tamil Nadu.
