A solar module's performance can degrade due to gradual reduction in output power or failure of an individual solar cell. Degradation mechanisms include:
Degradation to the module power requires an interaction causingcell-level defects. Degradation of silicon solar cells is dominated by four modes: potential-induced, light--induced, wafer cracking, and metal corrosion. These modes affect the cells in different ways and may range from almost no loss of power to complete loss of power. 4.1.
