The 320 Watt Monocrystalline Solar Panel is a versatile performer constructed with tempered glass and a stronger surface to protect from harsh weather conditions. The solar cells used in the panel provide high light transmission and the textured glass allows for more efficient power solar harvesting. The panel also includes a bypass diode that minimizes the power drop caused by shade. Easy to install using the pre-drilled holes on the aluminum outer frame. Perfect for home and industrial applications.
