Mobile on-site testing eliminates the need to send solar panels to a distant laboratory to minimize power plant downtime and maximize profitability. We provide you comprehensive on-site services designed to assure diverse stakeholders invested in your business. Fast and accurate power verification, electroluminescence and bypass diode test results directly in the field increase confidence in the optimal performance of your PV modules.

Our Mobile Solar Lab

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

Our innovative Mobile Solar Lab, 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 Mobile Solar Lab is equipped to perform Electroluminescence (EL) and bypass diode tests.

Results are promptly provided after testing has been completed.

Our comprehensive on-site solar panel testing services are designed to help:

Investors and power plant owners

  • Get reliable power measurements without having to send modules to a distant laboratory
  • Confirm acceptance of goods
  • Identify potential warranty claims

EPC contractors
