It is 450 watt half solar panel using company core technology half cutting technology so the quality is the best

Details

Our solar panels have highly efficient and stable diodes，to prevent the current recoil and stabilize the current
The most suitable angle for solar panel mounting is the horizontal 45 °;
Solar panels should be kept clean during normal use to ensure the surface is not blocked and extend their life
