Product description:

Engineered specifically to maximize Return on Investment (ROI) for large-scale developers and C&I project owners, our advanced TOPCon Bifacial Dual Glass Monocrystalline Module series delivers a highly efficient power output ranging from 430W to 450W. Utilizing high-quality silicon wafers, this module guarantees high power output and excellent cost-effectiveness, making it an ideal choice for large power plants. By pushing the boundaries of N-type technology, this module aggressively minimizes your Levelized Cost of Energy (LCOE) while ensuring your asset's long-term bankability and exceptional lifetime profitability.

Core Selling Points:

✅ Ultimate Generation Efficiency & Optimal Space Utilization:

Powered by cutting-edge TOPCon monocrystalline technology , this module delivers an exceptional maximum power output of 450W and an industry-leading maximum module efficiency of 22.50%. Engineered with lower oxygen and carbon content to ensure lower Light-Induced Degradation (LID), it guarantees outstanding sustained performance. We secure your yield with a 0~+3% power output guarantee , retaining 99.00% power after the first year and guaranteeing at least 87.40% capacity at year 30 under our comprehensive 30-year linear performance warranty.

✅ Superior Thermal Control & Exceptional Low-Light Performance:

Designed for ultimate climate resilience, this module features a highly optimized PMAX temperature coefficient of -0.300%/°C. Paired 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 extreme summer heat. Furthermore, the intelligent design of series and parallel connections reduces the series resistance (Rs) of the components, lowering internal electrical performance losses and improving the power generation capacity of the system across varying light conditions.

✅ Unwavering Long-Term Reliability in Harsh Environments:

Built to survive the toughest outdoor conditions, this robust dual-glass module operates flawlessly in extreme temperatures ranging from -40°C to +85°C and features a junction box with an IP68 protection level. It is engineered to withstand severe mechanical stress, supporting up to 5400 Pa of snow load and 2400 Pa of wind load. Rigorously tested for harsh environments, it guarantees superior weather resistance against sand blowing, salt mist, and ammonia corrosion (IEC 61701, IEC 62716), while utilizing selected packaging materials and strict process plans to ensure strict PID resistance.

✅ Comprehensive System Cost (BOS) Optimization:

Purpose-built to lower your Balance of System (BOS) expenditures, the module boasts highly optimized dimensions of 1762 x 1134 x 30 mm and a lightweight profile of approximately 21 kg for streamlined handling and installation. The finely tuned electrical parameters—including a Short Circuit Current (Isc) of 15.86A and an Open Circuit Voltage (Voc) of 35.64V for the 450W model—ensure perfect compatibility with mainstream high-power string inverters and advanced trackers. Supported by a 1500V DC maximum system voltage and a high 30A max series fuse rating, this module enables longer string configurations, drastically reducing the required cabling, combiner boxes, and mounting infrastructure.
