These 330W 72 cells polycrystalline solar panels from Chinese brand Yingli Solar, one of the largest solar panel manufacturers in the world.
Yingli Solar model YGE 72 Cell Series 2. Manufactured with high quality materials that allow optimal performance in any type of conditions and environments.
The circuit design of YGE series modules developed by Yingli has been optimized. Every piece of cells parallels a diode, when a cell is covered by shade, the paralleled diode can bypass this cell, thus avoide hot spot, and can retain the maximum power output. HSF module can be used in more shadowy and xomplex areas. Meanwhile, in land scarcity areas, the distance between modules has been shortened to increase the installed capacity.
