1: This type of half cell solar panels use 9 bus bars high efficient 166mm solar cells, and with 144 half cells that are cutted by 72 full size cells.
2: Advanced half cell technique improves the power of solar panels to around 5-10w.
3: With the improvement in output efficiency, the installation area decreases by 3%, and the installation cost decreases by 6%.
4: Half cell technique minimizes the risks of the cells’ crack and the damage of bus bars, therefore increases the stability and reliability of solar array.
5: It helps reduce the heat of solar panel by 1.6, this is because of the deduction in the instinct current and potential loss which leads to the operating temperature cool down.
