White solar panels are made with a special type of photovoltaic cell that is coated with a white film. This helps to reflect sunlight better, which increases the panel's efficiency.
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. The edge seal is the first line of defense against the elements.
The reasons for solar panels turning white can primarily be attributed to surface contamination, snow accumulation, aging materials, and manufacturing defects. Surface contamination includes elements such as dust and organic matter that block sunlight and degrade efficiency.
White stone defects (WSDs) appear as milky-white micro-cracks or mineral deposits within the photovoltaic glass layers. Think of them like cholesterol in arteries - they gradually block sunlight transmission while increasing internal reflection.
