Tamil Nadu Rooftop Solar Subsidy Now Up to ₹1 Lakh: What Changed in 2026
Rising TANGEDCO power tariffs have pushed household and commercial electricity bills higher across Tamil Nadu, making rooftop solar more attractive than ever. In the 2026-27 State Budget, Tamil Nadu announced a new Rooftop Solar Subsidy Scheme that works alongside the central PM Surya Ghar Muft Bijli Yojana — stacking a state top-up on the existing central subsidy to push the total benefit up to ₹1 lakh for eligible homes. If you've been waiting for the right time to go solar, 2026 is it.
2026 Subsidy Breakdown: What You Actually Get
| System Capacity | Avg. Monthly Generation | Central Subsidy | TN State Top-Up | Total Subsidy | Approx. Annual Savings* |
|---|---|---|---|---|---|
| 1 kW | ~120 units | ₹30,000 | Not yet notified | ₹30,000 | ₹9,000 – ₹11,000 |
| 2 kW | ~240 units | ₹60,000 | Not yet notified | ₹60,000 | ₹18,000 – ₹22,000 |
| 3 kW+ | ~360+ units | ₹78,000 | ₹22,000 | Up to ₹1,00,000 | ₹28,000 – ₹35,000+ |
The central scheme gives ₹30,000/kW for the first 2 kW and ₹18,000 for the 3rd kW, capped at ₹78,000 for systems of 3 kW and above. Tamil Nadu's new state scheme adds a further ₹22,000 on top for qualifying above-3kW installations, taking the combined benefit to ₹1 lakh.
Note: Savings vary by tariff slab, sunlight hours, and consumption pattern. The exact process for combining the state top-up with the central subsidy for systems under 3 kW hasn't been notified yet.
