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. This issue may affect the aesthetic appearance of the panels, but it does not generally impact their functionality or efficiency. When some chemicals are used to clean the panels' glass or if there are traces of this chemical in the air, acetic acid can develop, and low-quality panels' ethylene. . That discoloration is a visible symptom of a deeper problem: material degradation that silently steals your energy yield and shortens the lifespan of your investment.
