Abstract

A photovoltaic system includes a solar module having at least one solar cell. In order to reduce the power loss of the solar module when a solar module is in shade or is defective, a semiconductor switching element is connected in parallel with the solar module and drive electronics block the semiconductor switching element when the solar module is generating power and otherwise switch the semiconductor switching element to low impedance in order to bridge the solar module.
