Arrangement for avoiding unwanted degradation in no-load operation of solar cell modules composed of amorphous silicon

摘要

In order to avoid unwanted degradation in no-load operation of solar cell modules composed, in particular, of amorphous silicon, an internal load resistor is integrated in the module and is connected across the output terminals during no-load operation of the module. Disconnection of the resistor during load operation occurs either in a mechanical manner by way of a mechanical switch integrated in a plug extending to the load or occurs automatically by way of an electronic switch. The arrangement is employed in operation of solar cell modules for systems having a non-continuous power consumption such as, for example, appliances in mobile homes, mountain chalets and the like.
