Harrou et al. focused on detecting four types of PV failures on the DC side: open circuit, short circuit, partial shading, and degradation failures. In order to detect those failures accurately, they used a wavelet-based multiscale tool to separate the noisy measurement data.
They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
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.
