##

Adani Solar

Adani Solar is the solar manufacturing arm of the Adani Group. Although a newer entrant compared to Tata, Adani Solar is currently India's largest vertically integrated solar manufacturer.

Technical Specifications & Efficiency

Solar panel efficiency determines how much electricity a panel can generate in a given space.

| Feature | Tata Power Solar | Adani Solar |
|---------|------------------|-------------|
| Panel Types Offered | Polycrystalline, Mono PERC, Bifacial | Mono PERC, Bifacial, Half-Cut |
| Cell Efficiency | 20.0% – 21.2% | 21.0% – 22.2% |
| Temperature Coefficient| -0.37% per °C | -0.35% per °C |
| Performance Warranty | 25 Years (80% output) | 25 Years (80.5% output) |
| Product Warranty | 10 - 12 Years | 12 Years |

Key Takeaway: Adani Solar panels feature slightly higher average module efficiencies (up to 22.2%) due to newer manufacturing lines. Additionally, Adani's temperature coefficient is marginally better, meaning their panels lose slightly less power in Vadodara's intense summer heat (which often exceeds 42°C).
