The invention relates to solar modules (24, 64, 74, 84, 94) having at least two solar cell strings (25, 65, 75), wherein each string is galvanically isolated from the other strings. The invention further relates to solar modules that comprise a series diode (26), for example a Schottky diode, which is connected in series with the solar cells of the string so that the voltage provided by the solar cells polarizes the series diode in the flow direction. The invention further relates to module switches. A module switch comprises a control input (111) and a switching output (116) for short circuiting a solar module string. If an electrical signal below the threshold value is present at the control input (111), the two electrical connections of the switching output (116) are interconnected at low resistance, otherwise at high resistance. The invention further relates to solar cables having several electrical conductors insulated from each other. The invention further relates to busbars (8, 9) for solar systems, which have plug-in connectors for solar cables (33, 34, 35) having several electrical conductors. Finally, the invention relates to multiple-contact plug-in connectors for solar cables. |
