Indian Solar Buyer Advisory: India experiences extreme summer temperatures. Solar panel efficiency ratings are benchmarked at STC (Standard Test Conditions of 25°C). However, actual roof surfaces can exceed 60°C. **N-Type TOPCon** panels feature a significantly lower temperature coefficient (-0.30%/°C) compared to legacy Polycrystalline (-0.41%/°C). In hot regions like Gujarat, Rajasthan, or Uttar Pradesh, TOPCon panels produce **8% to 12% more total energy** during peak summers simply by resisting heat-degradation.
