ABSTRACT:
A protective circuit for electrical connection to solar cells of a solar cell module is provided with a protective circuit that has a controlled electronic circuit arrangement. In this way, only minimal heating of the protective circuit for electrical connection of solar cells of a solar cell module occurs in operation. The controlled electronic circuit arrangement can have a trigger circuit and a switching arrangement which can be triggered by the trigger circuit, the switching arrangement being connected parallel to at least one solar cell, and in the case of shading of the solar cells, is at least temporarily activated by the trigger circuit so that a current bypass for the shaded solar cell is achieved.
