Q : 1. What advantages does this panel offer over previous LONGi modules? A : It features higher efficiency, N-type TOPCon tech, slower degradation, and enhanced bifacial gain—making it ideal for high-yield projects.
Q : 2. What is the benefit of the 80% bifaciality? A : It allows up to 25% additional energy from the rear side under reflective surfaces, boosting total system output.
Q : 3. Can this panel handle extreme environments? A : Yes. It's tested to withstand –40°C to +85°C, 5400Pa front load, and hail impact at 23 m/s.
Q : 4. Is this module compatible with 1500V system designs? A : Absolutely. It supports 1500V DC system voltage and integrates easily with modern high-voltage string inverters.
Q : 5. What's the difference between this and a traditional P-type panel? A : N-type modules degrade slower, perform better in heat, and offer superior long-term output—resulting in a lower LCOE.
