Solar Cells: Photovoltaic (PV) cells are the heart of any panel, converting sunlight into direct current (DC) electricity. Over time, solar cells can crack or become discolored, especially due to UV exposure or heat stress, both leading causes of solar panel defects and power. . Why Not Use Cells Directly? The electrodes are exposed to air, making them prone to oxidation. A single crystalline silicon cell has low power output, with a voltage of only about 0. Cells have poor weather resistance. . Solar panels are generally low-maintenance, but occasional problems can arise. If you notice any issues with your system, take quick action to prevent them from getting worse. The reasons for delamination can be different: bad workmanship, poor. . As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up.
