4 Frequently Asked Questions about "Photovoltaic grid lines turn gray"

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.

Why do solar panels get discolored?

Solar Cells: Photovoltaic (PV) cells are the heart of any panel, converting sunlight into direct current (DC) electricity. Over time, solar cells can crack or become discolored, especially due to UV exposure or heat stress, both leading causes of solar panel defects and power loss.

Why do solar panels change color?

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.

How do UV rays affect solar panels?

Over time, UV rays can cause degradation of the materials used in solar panels, affecting both their appearance and efficiency. This exposure can lead to: 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.
