Arrangement for indicating a functional defect in solar cells

摘要

The invention relates to an invention for indicating a functional defect in solar cells (10) which are connected together in modules (2, 3, 4, 5). Provided on the back (8) of each of the individual modules (2, 3, 4, 5) is an indicating element (9) which emits a signal during normal operation of the module but does not emit any signal in the event of a defect. As a result, a system comprising numerous solar cell modules can readily be monitored. In addition, a further diode (12) is provided in antiparallel with the indicating element for each module as overload protection. <IMAGE>
