I-V characteristic

Measurement of PV modules’ I-V and P-V characteristics under actual environmental conditions. Different PV technologies  have been evaluated and their characteristics referred to the same radiation of 1 kW/m².

The electrical measurements were performed using prototype and market-available measuring equipments. Its operating principle is illustrated through the block diagram shown in figure.

Comparison among different technologies are performed. I-V curves, OV-, SCC-, MPP-values of OPV, CIGS and Si-c are measured and compared at different irradiance-temperature conditions
