Yellowing in PV Modules: Causes and Prevention
The primary cause of yellowing in PV modules is the degradation of EVA due to an uncontrollable chemical reaction from materials within the panel. Most solar panels use EVA as an
View DetailsWith 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.
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.
Central to the “why do solar panels change color” query is the role played by Ethyl Vinyl Acetate (EVA) – a type of plastic that seals the solar cells inside panels. EVA is initially translucent to allow sunlight to pass through to the cells.
However, over time under extreme temperatures, UV light, or humidity, EVA may suffer from an issue known as 'thermo-oxidative coloration,' turning yellow or brown. Simply put, it's kind of like when you leave a piece of clear plastic out in the sun and it starts to turn a yellowish hue.
