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.
White and coloured solar panels are a new technology developed to fill this demand for solar panels that could be customized to match a building's color, making them appear as an integral part of the structure rather than an addition or conspicuous patches.
The quick summary: New white solar panels combine modern aesthetics with improved energy generation efficiency up to 129W per square meter, enabling wider adoption of solar technology in building design.
