The high efficiency PV module adopts the world's highest efficiency wafer with efficiency up to 22%, and effcientcy of the moduls is 25%-30% higher than traditional ones. This cell's positive pole and the negative pole are on the same side, the cell's front side can absort maximum sunlight, so that it can get the maximum power. As for these advantages, 20% high efficiency solar module is widely used in Roof Power Generation System, solar Pumping System, Off-grid/Grid-tie Generation System etc. Different power and voltage of 20% High Efficiency solar Module can also be produced by cuting pieces to achieve.
