About this product
Product information from the supplier.
Our high-performance Polycrystalline Solar Panels are engineered with an advanced 5BB (5 Busbar) design to maximize energy harvest and ensure long-term structural durability. By significantly reducing cell series resistance and minimizing mechanical stress between interconnectors, these modules enhance power conversion efficiency, making them a premium choice for both residential rooftops and large-scale commercial solar installations.
Verified by TUV Rheinland, our modules deliver a robust power output of up to 280W with an impressive efficiency of 17.5%. To guarantee peak performance in diverse climatic conditions, each panel is equipped with professional anti-reflective and anti-soiling surface treatments, effectively minimizing power losses caused by environmental dust and debris while maintaining a stable energy yield.

Frequently Asked Questions
Q: What are the benefits of the 5BB design in solar panels?
The 5BB (5 Busbar) design reduces cell series resistance and lowers stress between interconnectors, directly improving power conversion efficiency and long-term reliability.
Q: How does the anti-soiling surface improve performance?
The anti-reflective and anti-soiling coating prevents dust and dirt from adhering to the glass, reducing power loss and decreasing the frequency of manual cleaning.
Q: Is this panel suitable for areas with heavy snow or wind?
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.
Q: What does "100% EL double-inspection" mean?
Electroluminescence (EL) inspection acts as an X-ray for solar cells. Double-inspection ensures micro-cracks or hidden defects are identified and removed before shipping.
Q: What is PID resistance and why is it important?
Potential Induced Degradation (PID) can cause significant power loss. Our PID-resistant technology prevents this degradation, maintaining high output over the panel's lifespan.
Q: Can these panels be integrated into existing solar systems?
Yes, they use standard MC4-compatible connectors and are designed for a maximum system voltage of 1000V, ensuring compatibility with most industry-standard inverters.
