Solar panel discoloration is typically the result of long-term exposure to the elements, such as sunlight, rain, and dust. This issue may affect the aesthetic appearance of the panels, but it does not generally impact their functionality or efficiency. This issue occurs due to the degradation of ethyl vinyl acetate (EVA), a material used as an encapsulant in the panel. Over time, solar cells can crack or become discolored, especially due to UV exposure or heat stress, both leading causes of solar panel defects and power loss. Frame: The rigid. . Think of your solar panels as the high-performance athletes of your home.
