This reaction happens between the lamination materials (including EVA) and the oxygen in the environment. With prolonged exposure to sunlight, the EVA starts to oxidize and causes the surface to change color. Dirt, dust, bird droppings, and other environmental factors can also cause solar panel discoloration.
EVA helps to maintain UV resistance in solar panels, with ultraviolet rays not being used by the panels, so when lower quality materials are used for this the resistance isn’t as good. Eventually, prolonged UV exposure starts to discolor the EVA, causing it to turn yellow or brown. Again, this happens after the first few years.
However, in the realm of solar panels, this discoloration is a deeper phenomenon with potential consequences. Solar panel discoloration is a physical change in the panel’s color due to environmental factors or material degradation, especially the yellowing or browning of their once clear and shiny surfaces.
A red or orange light during daylight hours indicates there's a system event or fault.” A low power situation occurs when your solar system does not deliver the amount of power that it is rated for. This is the most common issue, and a few easy troubleshooting steps can help you locate the cause of the problem.
With prolonged exposure to sunlight, the EVA starts to oxidize and causes the surface to change color. Dirt, dust, bird droppings, and other environmental factors can also cause solar panel discoloration. Furthermore, pollution has been linked to causing a greyish hue on solar panels.
Solar panel discoloration is very noticeable, with the formerly white portions across the surface of the cell turning into a yellow or brown color, and it tends to happen just a few years after installation.
