Outdoor electroluminescence and reverse current thermography

The VDE 0126-23 Standard now specifies a commissioning test procedure for solar systems. Measurement of the no-load voltage, short-circuit current and insulation resistance. There is now a measuring device, the Benning PV-1, which can carry out all of these measurements in a single pass. The measured values are recorded and the documentation supplied to the […]

pvServe – a service power supply for the photovoltaics industry

The first reverse current testing of solar modules took place some years ago during IEC tests on solar modules. It requires a voltage greater than the module’s no-load voltage to be applied to the module’s terminals. The module then behaves like a circuit with 60 or 72 diodes in series (depending on how many cells […]
