From April through June, daytime temperatures across Patna, Gaya, Nawada, and Bhagalpur frequently cross 43°C—causing standard solar modules on concrete roofs to run hot and lose efficiency. Switching to Waaree N-Type TOPCon Bifacial Modules mitigates heat derating while harvesting reflected light off light-colored roof tiles or waterproofing.
Key Advantages for Bihar Rooftops
- Superior Efficiency (22.3%+): Packs higher wattage into tight urban terrace spaces where shading from water tanks limits panel count.
- Lower Annual Degradation: Zero LID (Light-Induced Degradation) retains over 87% rated power output even at Year 25–30.
- Bifacial Rear Gain: Generates 8% to 18% additional units when installed on elevated white-painted roofs or pergola structures.
