Conversion yield

Correlation between the supplied power for a PV element and the received solar power. For example, if a square cell of 0.1m side length receives a 1000W/m2 solar irradiance and supplies a 1.2W electrical power, its conversion yield is: 1.2W / (1000W/m2 x 0.01m2) = 12%. It is important to distinguish the intrinsic conversion yield of the cells used and the one of the PV modules (that depends on the relation between the active surface and the total surface).
