Is the back of the photovoltaic panel white or yellow

“Around the back of the module, we often see the backsheet is no longer white, it's turning various shades of yellow and, in bad cases, almost brown. ” Yellowing leads to cracking and sometimes delamination. . Imagine a vast solar farm, its panels shimmering under the intense desert sun—a powerful image of modern technology silently converting light into clean energy. But look closer, and you might see a subtle, unwelcome change: a gradual yellowing of a panel's backing. . They can turn brittle and, most notably, a yellowish color. A yellowing backsheet is more than just an unattractive color change; it's usually the first sign of a mechanical breakdown and a warning that more drastic consequences aren't far off.
