Q : 1. How is this panel different from regular bifacial modules? A : It uses TOPCon 2.0 and µc-Si gettering to boost both front and rear power output efficiency.
Q : 2. Is it suitable for hot climate and desert installations? A : Yes, it performs stably in heat, with a low –0.30%/°C power temperature coefficient and sand-resistant glass.
Q : 3. What is the real-world energy gain from bifaciality? A : Up to 90% bifaciality allows significant rear-side gain depending on ground reflectivity and mounting height.
Q : 4. How does it perform long-term in outdoor conditions? A : It's sealed with PIB, resists moisture, and complies with IEC/ISO standards for salt, ammonia, PID, and sand.
Q : 5. What kind of mounting and system is it compatible with? A : Supports 1500V systems and works well in fixed-tilt or tracker systems for utility-scale solar farms.
