Our mobile PV TravelLab

Photovoltaic (PV) TravelLab procedure for on-site mobile testing of solar panels | TÜV Rheinland
PV TravelLab mobile testing procedure

Our innovative PV TravelLab, which meets the requirements of IEC 61215 and IEC 60904 series of standards, provides a mobile testing laboratory compact enough to be easily transported by plane as oversized baggage.

After set-up and calibration, it is possible to test 150-200 PV modules per day. The measurement uncertainty for highly efficient crystalline modules, thin-film modules, PERC or HJT solar cells lies within 2,5%. Also, the PV TravelLab is equipped to perform Electroluminescence (EL) and bypass diode tests.

Results are promptly provided after testing has been completed.
