Example for power rating measurement results at CalLab PV Modules

Measurement of I/V characteristic at various irradiance levels of PV module to determine the irradiance dependence. The characteristics are recorded in the range of 100 to 1100 W/m², with an interval of 100 W/m² and a module temperature of 25 °C.
