As a parallel event of the 38th EU PVSEC, the session “Qualification of PV Power Plants using Mobile Test Equipment” organized by the International Energy Agency (IEA) Photovoltaic Power Systems Programme (PVPS) Task 13, will present on-site inspection methods and techniques to qualify PV power plants. The presented on-site inspection methods are helpful tools to identify drivers for underperforming PV power plants. Their particular strength lies in the fact that the tests are carried without dismantling and shipping the PV modules to a laboratory, which often means long transport routes, transport risks and a long down time of the PV strings. Furthermore, on-site inspection methods allow a more targeted failure analysis, as PV modules are not blindly selected. The quality and significance of the inspection results are comparable to that of laboratory tests.
Besides technical information and field experience, good practice recommendations for field use and evaluated uncertainties compared to laboratory inspection methods will be presented and discussed with the experts.
