Degradation rates must be known in order to predict power delivery. This article reviews degradation rates of flat-plate terrestrial modules and throughout the last 40years.

Why is degradation of a PV module important?

Financially, degradation of a PV module or system is equally important, because a higher degradation rate translates directly into less power produced and, therefore, reduces future cash flows . Furthermore, inaccuracies in determined degradation rates lead directly to increased financial risk .

Does light induced degradation affect photovoltaic conversion efficiency?

Passivated emitter and rear cell (PERC) photovoltaic (PV) modules' conversion efficiency is also affected by light-induced degradation . LID has been observed in four main categories. They have traditionally included Iron Boron (FeB) and Boron Oxygen (B-O) LIDs; newly reported LIDs are sponge-LID, bright, and elevated temperature LID (LeTID).
