No one will actually answer this question. The fact is that photomodules are a relatively new energy technology, and the full cycle of their operation is not known to anyone. But as practice shows, even the first montages are still active and work efficiently! A good example is the 80-watt Kyocera solar panel, which was purchased in 1979 by American Ralph Jimenez. After 40 years of operation, although it has lost about 30% of its rated capacity, it is still used as intended. The main component of a long service life is the protection of the panels against damage.
