Low Degredation Of Solar Cells Over Time
20-year-old installation of Kyocera 945-watt solar modules in France still performs with a high power output level. The evaluators found that, after 20 years, the panels’ power production declined by only 8.3%. Usually an economic lifespan of 20 years is attributed to solar panels. Due to the gradual nature of deterioration however, this means that the panels could last many more years before becoming useless.
