The possibility that discoloration in solar panels could result in less energy being produced is one of the main causes of concern. Microcracks in the silicon of the solar cells frequently cause discoloration. These tiny fissures weaken electrical connections. So, there are fewer routes for electrons from the sun to travel.
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.
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.
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.
