Do scratches on photovoltaic panels have any impact
Minor scratches typically do not significantly impact a solar panel's performance. However, deep scratches can reduce efficiency by obstructing sunlight from reaching the photovoltaic cells. . Industry standards like IEC 61215 define general defect categories, but they lack a specific, actionable protocol for classifying scratches on the glass and backsheet—the two most critical protective layers of a solar module. This guide lays out a simple, effective framework for differentiating. . If the surface of solar panels becomes scratched, addressing the issue is essential to maintain their efficiency and longevity.
