We find that the wider the white sheet around the photocell, the greater the increase of electrical current generated in it. These results will help to the optimization of the design of solar panels.

To effectively manage white spots on solar panels, consider the following key strategies: 1) Regular cleaning, which removes dirt and debris that contribute to white spot formation, 2) Inspecting for surface damage, ensuring that any cracks or faults are identified early .

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 spots are a sign of irreversible changes within the module's sealed laminate. Once delamination or material degradation has occurred, it cannot be reversed. That's why prevention through quality.
