Introduction
Solar energy adoption is growing rapidly across Tamil Nadu. Whether for your home or business, switching to rooftop solar helps save money and supports a sustainable future. But how do you start? What subsidies are available? How much will it cost?
This guide by Glow Solar Power Solutions answers these key questions and helps you make an informed decision.
Government Subsidies in Tamil Nadu
Both the Central and State Governments offer attractive subsidies for residential solar installations.
For instance, homeowners can receive up to ₹30,000 per kW under government schemes.
Tamil Nadu also provides an additional incentive of ₹20,000/kW through the Chief Minister’s Solar Rooftop Capital Incentive Scheme.
Always ensure your installation partner is MNRE-approved to claim subsidies without hassle.

Actual Cost & Savings
A 3 kW rooftop solar system typically costs between ₹1.5 – ₹1.8 lakhs before subsidy.
After applying government subsidies, your effective cost can drop by 30–40%.
In most Tamil Nadu households, the investment is recovered within 3–4 years through electricity bill savings.
Cities like Coimbatore, Chennai, and Madurai are now leading in rooftop solar installations across the state.

Net Metering Explained
After installation, your solar system connects to the TANGEDCO grid through a net meter.
This allows you to export excess power generated during the day and import electricity at night.
The difference (net energy) is automatically adjusted in your monthly bill — helping you save even more.
Always choose a certified installer to handle grid approval smoothly.
