What s the matter with white spots on photovoltaic panels
The most common cause of white spots is moisture seeping into the module laminate. A solar module is built like a sandwich, with the solar cells and encapsulant sealed between glass and a backsheet.

[PDF Version]FAQs about What s the matter with white spots on photovoltaic panels
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 do you know if a solar panel has a hot spot?
You can detect an emerging hot spot with an infrared camera only. Eventually, hot spots in solar panels become visible to the eye: the problematic cell becomes brownish. Hot spots lead to a faster solar panel degradation and can even start a fire on your roof. To avoid that, clean your panels from dirt every now and then.
What causes hot spots on solar panels?
Hot spots can stem from overshadowing, dirt or microcracks. When the sunlight hits solar cells, it is supposed to be converted into electricity. However, if the resistance of one solar cell rises, this part of the panel heats up. This is the hot spot – overproportional heating of one cell compared to the others.
What causes solar panels to discolor?
Environmental factors: Extreme weather conditions, including cold and hot temperatures, humidity, snow, and ice, slowly contribute to solar panel degradation. These elements can accelerate the discoloration process and potentially shorten the panel's lifespan.
