4 Frequently Asked Questions about "What are the stains on photovoltaic panels "

What causes solar panel discoloration?

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.

What are the different types of solar panel discoloration?

Let's explore the most common types of solar panel discoloration: One of the most noticeable forms of discoloration is the yellowing or browning of the solar panels. This issue occurs due to the degradation of ethyl vinyl acetate (EVA), a material used as an encapsulant in the panel.

How does UV damage a solar panel?

UV radiation harms the panel's surface and its internal parts. It penetrates deep and causes long-term damage. Water in solar panels causes discoloration and lowers performance. Even with impermeable glass backs, moisture can enter through the edges over 20 years.

Why do solar panels turn grey?

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.
