Key Technology

• PERC+ Half-Cut Cell Architecture
Half-cut PERC+ cells reduce resistive losses, improve shade tolerance, and increase overall module efficiency, especially in high-heat or low-light conditions.

• Bifacial Dual-Glass Power Generation
The module uses bifacial cells paired with 2.0 mm front and back glass, enabling additional rear-side energy capture. Depending on the ground surface and installation design, this can deliver significant production boosts and lower the system’s LCOE.

• Non-Destructive Cell Cutting
The manufacturing process uses mechanical separation rather than laser scribing, which helps protect the silicon lattice, minimizes micro-cracks, and supports long-term reliability.

• PID-Resistant Module Design
Engineered to mitigate potential-induced degradation, allowing the panel to maintain stronger performance over time in environments with high heat, humidity, or system voltage stress.

• Low BOS and Reduced LCOE
Higher wattage per module means fewer panels, less racking, reduced wiring, and lower installation labor. This results in lower balance-of-system costs and a more cost-efficient energy yield over the life of the system.

• High Mechanical Load Strength
The enhanced dual-glass structure and reinforced frame support up to 5400 Pa front-side and 2400 Pa back-side loads, improving durability in snow, wind, and challenging weather conditions.

• High Module Conversion Efficiency
With maximum module efficiency up to 21.7%, the module offers strong performance in constrained spaces where watts per square foot matter.

• Optimized for Long-Term Output
The panel is built for extended service life, combining slow degradation rates with durable dual-glass protection, high weather resistance, and stable PERC+ cell behavior.

Warranty
