The lifespan of solar panels generally ranges from 25 to 30 years, depending on the quality of the panels and the environmental conditions in which they are installed.
Initially: Solar panels operate at their peak efficiency.
Over time: Efficiency may decrease slightly each year. Typically, solar panels will continue to operate at about 80% of their original efficiency after 25 years.
Additionally, proper maintenance and correct installation can significantly extend the lifespan of solar panels.
