The disclosure relates to a roof covering element, a solar roof covering element, to an assembly of solar roof covering elements, and to a method for producing a solar roof covering element. A roof covering element and a solar roof covering element are to be provided for a solar roof system, which can be produced by means of a cost-effective mass production process and which enable a simple and cost-effective roof mounting. The disclosure is characterized by a roof covering element with a flat main part, the upper face of which has a receiving surface for a solar module and which has an opening or a bore running perpendicularly to the main surface, at least two electrical lines being guided together through said opening or bore, wherein the lines end on the upper face of the main part in the region of the receiving surface as contact means, said contact means being held or guided in an axially movable manner in a common flat connection socket, the electrical lines being guided in a common plug-in socket from the lower face through the opening or the bore and wherein the plug-in socket on the lower face of the main part is held in the axial plug-in direction in an interlocking manner by a plug-in flange and on the upper face of the main part is held against its axial plug-in direction in an interlocking and/or force-fitting manner by a locking means and forms the connection socket on the upper face of the main part.

A power supply power supply () comprising a DC voltage supply, a control unit and a plurality of high voltage channels (-) is suggested. Each high voltage channel () includes an inverter (IKTV), a resonance circuit, a transformer (TR), and a rectifier (RECT). The resonance circuit cooperates with the inverter (INV). The inverter (INV) is formed by a first switching unit and a second switching unit whereby a voltage of a first polarity can be applied to the resonance circuit in a first switching state, whereas a voltage of a second polarity can be applied to the resonance circuit in a second switching state. The switching states can be switched by the control unit in such a manner that in a first mode of an operation for high output power, the output power can be adjusted by changing the switching frequency in the range of the resonance frequency. In a second mode of operation for low output power, the output power can be adjusted by changing the duration of the switching state at an essentially constant switching frequency.
