Device for the industrial wiring and final testing of photovoltaic concentrator modules consisting of a module frame, a lens pane, a sensor carrier pane, and an electric line guide, comprising the following features: a) a laser contacting arrangement for contactlessly connecting connection lines between the individual sensors and connection elements and collector contact plates, wherein the line guide on the sensor carrier pane has in each case 5 CPV sensors connected in parallel as the basic structure, and these parallel connections are connected in series, and wherein the electric connection lines, connection elements and collector contact plates to be applied to the sensor carrier pane are removed automatically from a stored supply and are brought into the region of corresponding holding means, and wherein the contact partners, before the connection by means of a laser contacting arrangement, are fixed in their target position by automatically controlled holding means, and wherein the laser contacting arrangement ensures that the two conductors to be connected are not contacted by the connection tool, are heated only for a very short period of time, and therefore practically do not deform, and wherein the positioning of the holding means is oriented in a laser-controlled manner toward markings on the concentrator module, b) an arrangement for testing electrical properties, wherein a certain voltage is applied to CPV sensors themselves and the light emitted therefrom via the lenses is detected and evaluated, wherein identified manufacturing faults are corrected, c) an arrangement for testing the tightness of finished concentrator modules, wherein compressed air is applied to the interior of these modules and testing for the emission of compressed air is performed. a) a laser contacting arrangement for contactlessly connecting connection lines between the individual sensors and connection elements and collector contact plates, wherein the line guide on the sensor carrier pane has in each case 5 CPV sensors connected in parallel as the basic structure, and these parallel connections are connected in series, and wherein the electric connection lines, connection elements and collector contact plates to be applied to the sensor carrier pane are removed automatically from a stored supply and are brought into the region of corresponding holding means, and wherein the contact partners, before the connection by means of a laser contacting arrangement, are fixed in their target position by automatically controlled holding means, and wherein the laser contacting arrangement ensures that the two conductors to be connected are not contacted by the connection tool, are heated only for a very short period of time, and therefore practically do not deform, and wherein the positioning of the holding means is oriented in a laser-controlled manner toward markings on the concentrator module, b) an arrangement for testing electrical properties, wherein a certain voltage is applied to CPV sensors themselves and the light emitted therefrom via the lenses is detected and evaluated, wherein identified manufacturing faults are corrected, c) an arrangement for testing the tightness of finished concentrator modules, wherein compressed air is applied to the interior of these modules and testing for the emission of compressed air is performed.
