The 5BB (5 Busbar) design reduces cell series resistance and lowers the stress between cell interconnectors, which directly improves the power conversion efficiency and long-term reliability of the module.
The anti-reflective and anti-soiling coating prevents dust and dirt from adhering to the glass surface, reducing power loss and decreasing the frequency of manual cleaning.
Yes, these panels are certified to withstand high mechanical loads, specifically up to 2400Pa for wind loads and 5400Pa for snow loads, ensuring durability in harsh environments.
Electroluminescence (EL) inspection is like an X-ray for solar cells. Double-inspection ensures that micro-cracks or hidden defects are identified and removed before the product leaves the factory.
Potential Induced Degradation (PID) is a phenomenon that can cause power loss in solar modules. Our PID-resistant technology prevents this degradation, maintaining high power output over the panel’s lifespan.
Yes, they use standard MC4 or MC4-compatible connectors and are designed for a maximum system voltage of 1000V, making them compatible with most industry-standard inverters and mounting systems.
