Solar Modules include a frame with a groove for placing a solar light collecting device. The solar light collecting device is composed of a substrate and a solar cell that is completely wrapped by an encapsulating film under the substrate. The solar cell is also A back film is provided, and a reflective film for reflecting sunlight to the solar cell sheet is provided at the edge above the substrate.
High Efficiency Solar Panels is mostly used in the production of high-quality solar lamps, and the conversion efficiency of charging is higher than that of polycrystalline solar panels.

Solar Modules

Bifacial Solar Modules with higher efficiency(up to 20.93%)benefit from half cell structure(low resistance characteristic ), Multi busbar technology provide with better light utilization and current collection capabilities, effectively improving product power output and reliability. Excellent double-sided warranty promises a 30-year power warranty of 0.45% linear power attenuation to ensure longer service life. Passed severe weather resilience to withstand:Wind load (2400 pascal) and snow load (5400 pascal). Double-sided power generation gain increases with the light received on the back side, up to 25%, which significantly reduces the LCOE.

High Efficiency
