Ultra-Lightweight and Thin Design - Weighing just 5lbs and measuring only 2mm in thickness, it is exceptionally lightweight and thin. This is achieved through advanced lamination technology, setting a market-leading standard for ease of handling and mobility.

Superior ETFE Covering Material - Utilizing ETFE instead of PET, the solar panels offer superior durability, resisting denomination over extended periods. ETFE properties include self-cleaning, scratch resistance, sand resistance, and impact absorption, making it ideal for withstanding the wear and tear encountered during transportation and maintenance.

High Conversion Efficiency with 9BB Technology - The 100W flexible solar panels feature a cutting-edge 9BB (9-busbar) cell design, boasting a maximum conversion efficiency of 23%. This design increases the cells surface area, reducing shading losses and extending the panel’s service life. The thinner ribbon structure covers 23% less area, improving overall power output.
