Product description:

Designed specifically to deliver high Return on Investment (ROI) for large-scale developers and C&I project owners, our ultra-efficient N-type TOPCon 16BB Bifacial Dual Glass Module series produces between 490W and 505W of maximum power output. High quality silicon wafers guarantee high power module output and excellent cost-effectiveness, making it an ideal choice for large power plants. By pushing the boundaries of solar technology, this module minimizes your Levelized Cost of Energy (LCOE) while maximizing lifetime asset profitability, ensuring your solar investments are both bankable and future-proof.

Core Selling Points:
✅ Ultimate Generation Efficiency & Optimal Space Utilization:

Powered by advanced 182mm 16BB TOPCon cell technology , this monocrystalline module delivers a peak maximum power output of 505W and an industry-leading maximum module efficiency of 23.30%. The cells feature lower oxygen and carbon content, which directly leads to lower Light-Induced Degradation (LID). Furthermore, it provides a 0~+3% power output guarantee , retaining 99.00% power after the first year and a guaranteed 87.40% capacity at the end of its 30-year linear performance warranty.

✅ Superior Thermal Control & Exceptional Low-Light Performance:

Engineered for ultimate climate resilience, this module boasts an outstanding Pmax temperature coefficient of -0.300%/°C. Coupled with a low Nominal Operating Cell Temperature (NOCT) of 44±2°C, your system will experience minimal power loss and maintain high-efficiency generation even during peak summer heat. The design of series and parallel connection reduces internal electrical performance losses, improving the overall power generation capacity of the system across various lighting conditions.

✅ Unwavering Long-Term Reliability in Harsh Environments:

Built to survive the toughest conditions, the robust bifacial dual-glass architecture features an IP68-rated junction box and operates flawlessly in extreme operational temperatures ranging from -40°C to +85°C. It is engineered to endure severe mechanical stress, supporting up to 5400 Pa of snow load and 2400 Pa of wind load. The module is rigorously tested for harsh outdoor environments, successfully passing weather resistance tests for sand blowing, salt mist, and ammonia corrosion (IEC 61701, IEC 62716), as well as rigorous PID testing.

✅ Comprehensive System Cost (BOS) Optimization:

Purpose-built to lower your Balance of System (BOS) costs, the module features highly optimized dimensions of 1908 x 1134 x 30 mm and weighs approximately 28.4 kg. The finely tuned electrical parameters—including a Short Circuit Current (Isc) of 14.71A and an Open Circuit Voltage (Voc) of 43.56V for the 505W model —ensure seamless electrical synergy. With a maximum system voltage of 1500V DC and a max series fuse rating of 25A, this module allows for longer string designs, significantly reducing the need for excessive cabling, combiners, and mounting infrastructure.
