Abstract
A method for checking the operation of a photovoltaic module of a photovoltaic power station. The module has a positive terminal, a negative terminal and a number of solar cells, in particular thin-layer solar cells. An electric field emitted by the photovoltaic module as a result of solar radiation is measured at an exposed measurement location during the operation of the power station and the electrical voltage present between the positive terminal and the negative terminal is determined from the measured electric field. A corresponding measuring instrument has a sensor to be placed near the photovoltaic module so as to measure the electric field strength. A rod or wand may be used to position the sensor, or a robot may be configured for automatic travel on the photovoltaic module.
