Buy 320W Polycrystalline Solar PV from Chinese Factory
Current classifiaction reduce Mismatch loss
Low hot spot temperature higher safety performance
Low power loss under shadows
5BB reduce the current heat loss of the battery inside the module,beautiful apperance,more suitable for roof installation
