Solar panel delamination occurs when internal layers of the module, particularly between the glass, encapsulant, and backsheet, begin to separate. This separation allows moisture and air to infiltrate the panel, leading to busbar corrosion, solar panel discoloration, and. . Common solar panel defects, such as discoloration, delamination, and solar panel diode failure, often become more likely as systems age. These issues reduce overall efficiency and may lead to more expensive repairs if not addressed promptly. Weather-related solar panel damage is also on the rise. This decline is usually measured as a percentage of annual power output lost. . Solar panel degradation is a natural process characterized by a gradual decrease in efficiency and power output over time, influenced by environmental conditions, solar cell materials, and manufacturing quality.
