Can a solar panel last 50 years?

Both a 2012 photovoltaic degradation rate study and a 2015 degradation study, performed by NREL, found a solar panel degradation rate mean of 0.8 percent and a median of 0.6 percent. With these factors in mind, a solar array can last 40 to 50 years.

Do solar panels need servicing?

Is solar panel servicing necessary? Solar PV systems require little maintenance besides keeping them relatively clean (rain will do this for you, if your panels are tilted at least 15 degrees) and making sure theyre not shaded by trees.
