众所周知如果没有防辐射层，太阳紫外线的辐射会破坏板材，从而导致阳光板的黄化、风化。UV防辐射层可以有效抵挡紫外线的破坏，以太阳紫外线每年破坏5微米的UV层计算，阳光板表面若共挤有50微米UV层，可确保阳光板使用十年，甚至不会变黄。因此选择具有防辐射层的阳光板很重要。
It is well known that if there is no radiation protection layer, solar ultraviolet radiation will damage the plate, leading to the yellowing and weathering of the plate. UV radiation protection layer can effectively withstand the damage of ultraviolet radiation. Calculated by solar ultraviolet radiation destroying 5 micron UV layer every year, if there is 50 micron UV layer on the surface of the solar panel, it can ensure that the solar panel will be used for ten years, or even not yellowing. Therefore, it is very important to choose a solar panel with an anti-radiation layer.
