Photovoltaic failure is not defined uniformly in the literature. Some definitions indicate that a drop of 80% in maximum output power is considered a PV failure . Others claim a 20% drop in maximal power is a PV failure . Durand and Bowling defined failure as a drop of more than 50% in maximum power output.
