Product Overview
Engineered for Your Energy Project
Key Advantages of 660W TOPCon Bifacial Solar Module ⚡ Up to 665W Power Output 645–665W power range with module efficiency up to 24.62%, helping reduce BOS cost and improve project value. 🌡 Better High-Temperature Performance Low power temperature coefficient of -0.29%/°C helps maintain stable output under hot operating conditions. ☀ Bifacial Energy Gain Bifacial design captures additional rear-side irradiation, increasing total energy yield depending on installation conditions. 🛡 Long-Term Reliability 30-year linear power warranty with annual degradation of no more than 0.4% supports reliable long-term operation. N-type vs P-type Solar Cell Comparison
N-type solar technology offers higher efficiency, lower degradation, and better long-term performance compared with conventional P-type modules.
Comparison Item N-type TOPCon Conventional P-type
Cell Efficiency Higher conversion efficiency Relatively lower efficiency
Power Output Higher module wattage potential Lower output under the same module size
Degradation Lower first-year and annual degradation Higher degradation over time
Temperature Performance Better performance in hot climates Less stable under high temperatures
Bifacial Gain Better rear-side power generation potential Usually lower bifacial performance
Energy Yield Higher lifetime energy generation Lower long-term yield
LCOE More competitive long-term cost per kWh Higher lifetime system cost
Project Value More suitable for utility and C&I projects Suitable for cost-sensitive conventional projects
For commercial and utility-scale projects, N-type TOPCon modules provide better long-term returns through higher efficiency, lower degradation, and improved energy yield.
