Solar panel discoloration is typically the result of long-term exposure to the elements, such as sunlight, rain, and dust. This issue may affect the aesthetic appearance of the panels, but it does not generally impact their functionality or efficiency.

It happens when a difference in electrical potential between the solar cells and other panel materials, like the frame, causes ions to migrate. This can create a kind of “shadow” or dark patch on the panel.

Phase Change Materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting & freezing (changing from one phase to another).

In solar panel technology, the colors that play a critical role are primarily blue and red. Photons in the blue spectrum carry higher energy than those in the red spectrum.
