The 5BB (5 Busbar) design reduces the distance electrons travel, lowering cell series resistance and reducing stress between interconnectors, which significantly boosts the module’s overall conversion efficiency.
The anti-reflective and anti-soiling coating prevents dust, dirt, and grime from sticking to the glass, ensuring maximum sunlight penetration and reducing maintenance frequency.
This means the actual power output of the module will never be lower than the rated power (330W) and could be up to 3% higher, ensuring guaranteed energy delivery.
Yes, these modules are certified to withstand snow loads up to 5400Pa, making them highly durable for alpine or northern climates.
Electroluminescence (EL) inspection is like an X-ray for solar cells. Double-inspection ensures that micro-cracks or inactive areas are identified and removed, guaranteeing a defect-free product.
Bypass diodes allow current to flow around shaded cells, preventing "hot spots" from forming, which protects the module from permanent damage and maintains system output during partial shading.
