Abstract
A circuit breaker for a solar module, wherein a plurality of solar cells working in normal operation and when shaded are connected in series. At least one controlled electrical switch element serves as a bypass element and is connected in parallel with its contact gap to a plurality of solar cells. A supply circuit provides a control voltage for controlling the control electrode of the bypass element. An isolating circuit blocks the voltage applied to the contact gap of the bypass element in the normal operation and switches the voltage that is applied to the contact gap to the supply circuit when at least one solar cell is shaded.
