PV cells test bench system with remote access trough Internet

A test bench system for testing the solar cells is presented. The system allows remote access through Ethernet in order to measure the I-V characteristics at different levels of lighting and the dynamic behaviour of solar cells using light or current pulses. The paper presents two different solutions and emphasizes their advantages allowing high accuracy in the measurement of the PV cell parameters. The paper shows the architecture and elements of a data acquisition system that was developed based on high resolution ADCs. The user interface is implemented in the LabVIEW environment.
