An inverter for converting the direct current provided by a solar generator to alternating current includes a control providing a control signal for a drive of the solar generator, for allowing tracking the solar generator after the sun, wherein the control is integrated in the inverter.

A solar cell module and a method for the production thereof, are used in particular in the field of concentrating solar technology. The solar cell module has a large number of two-dimensionally disposed solar cells. These solar cells are applied on a substrate which is coated with a metal layer on the surface orientated towards the solar cells. The metal layer is thereby structured in such a manner that it is subdivided into individual two-dimensional portions which are assigned respectively to one solar cell. The metal layer in each of the portions has two regions which are electrically insulated from each other, the first region extending under the assigned solar cell and contacting the latter in an electrically conductive manner. The second region is likewise connected to the other electrical contact of the solar cell. In order to produce a parallel and series circuit of the individual solar cells, the individual portions of the metal layer are now connected to each other in a suitable manner by means of connecting portions which, for their part, are part of the metal layer.
