Hi gh er Efficiency: Our 300watt solar panel raises the bar on conversion efficiency, reaching heights of up to 26.5%.
Superior Efficiency from BC Technology:By moving all electrical contacts to the rear of the cell, the entire front surface captures sunlight. This innovative design minimizes energy loss and achieves a higher conversion efficiency, generating more power in the same space.
Enhanced Performance with 10BB Design: The 10BB rear contact configuration reduces internal resistance and improves current collection. This leads to higher energy output, better performance in low-light conditions, and increased overall reliability.
Reduced Shading & Soiling Losses:The absence of front metal electrodes (grid lines) significantly decreases shading on the cell surface. Furthermore, the smooth front face discourages dust and debris accumulation, ensuring consistent energy production over time.
Excellent Reliability & Durability:The simplified cell interconnection at the rear enhances mechanical strength and reduces stress points. Combined with robust, weather-resistant framing, this panel is built to deliver stable performance for decades.
