Tamil Nadu Rooftop Solar Subsidy Scheme: Key Details and Assistance Structure

Overview of the Tamil Nadu Rooftop Solar Subsidy Scheme

The Tamil Nadu Rooftop Solar Subsidy Scheme is a State government initiative designed to make rooftop solar panel installations more affordable for domestic electricity consumers. Approved through a Government Order, the scheme provides additional financial assistance from the State alongside the central assistance available under the Pradhan Mantri Surya Ghar Muft Bijli Yojana.

The initiative aims to encourage households to adopt renewable energy, lower their electricity expenses, and increase clean energy usage across the State. According to available details, the scheme is targeted to benefit 1 lakh domestic electricity consumers with a budget allocation of ₹50 crore.

Subsidy Structure and Financial Assistance

Eligible households can receive a combined central and State subsidy of up to ₹1 lakh for installing residential rooftop solar systems. The financial assistance is distributed based on the capacity of the installed system:

• Up to 1 kW System: Central subsidy combined with a State top-up of ₹5,000 (total assistance up to ₹35,000).
• Up to 2 kW System: Central subsidy combined with a State top-up of ₹10,000 (total assistance up to ₹70,000).
• 3 kW and Above Systems: Central subsidy combined with a State top-up of ₹22,000 (total assistance up to ₹1 lakh).

The State subsidy is credited directly to the beneficiary's bank account through Direct Benefit Transfer (DBT) after successful installation, net-metering, commissioning, verification, and disbursal of the central subsidy.

While final guidelines may be subject to revision by the State government, tentative eligibility parameters include:
