Tamil Nadu is leading India’s solar revolution. With the government offering up to ₹78,000 subsidy under the PM Surya Ghar scheme, there has never been a better time to switch to solar.

But here is the challenge: With 500+ installers in the market, who do you trust? Some are big brands with high costs, while others are local players with poor service.

To help you decide, we have analyzed the Top 10 Solar Companies in Tamil Nadu for 2025 based on:

• Installation Quality (Structure & Safety)
• Customer Service (After-sales support)
• Pricing (Value for money)
• Technology (Latest Bifacial/Mono PERC panels)

Here is the definitive list.

1. Asian Power Tech (The Top Choice 🏆)
