6 FAQs about [The bottom of the photovoltaic panel turns white]

What does solar panel discoloration look like?

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.

What causes solar panel discoloration?

For example, certain chemicals used to treat the glass panels react with chemicals used in the silicon cells, resulting in the formation of acetic acid, which is one of the leading causes of discoloration. However, there is an even more common cause of solar panel discoloration – exposure to sunlight.

Why do solar panels have black backsheets?

Full black solar modules with black backsheets are especially important in residential applications that value aesthetics over performance. It is especially important to keep the solar cell colours uniform on full black panels to prevent blotchy colours on black roofs. Uneven solar cell colours can result in disappointing full black installations.

How to prevent discoloration in solar panels?

Unfortunately, there are few measures that you can take to prevent discoloration in solar panels, as it’s often the result of low quality EVA, meaning the best way to stop it from happening is to ensure you buy from a reputable manufacturer using top quality materials for the back sheet.

Why do solar panels change color?

Over time, solar panels may change color due to different factors such as sunlight exposure, variations in the antireflection coating, and exposure to UV rays. This discoloration can impact the panel’s performance, leading to decreased efficiency and reduced power output.

Why do solar panels turn yellow?

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.
