An apparatus for the automatic assembly of photovoltaic panels with back-contact architecture, characterized in that it comprises a series of stations (19, 24, 26, 28, 33, 35) that are configured in sequence in a carousel with recirculation of trays and a device (21, 25, 27, 32), which is adjacent to one or more of said stations (19, 24, 26, 28, 33, 35), for controlling the correctness of the processes performed, said control device (21, 25, 27, 32) enabling the processing or the mere transit of said tray into the subsequent station by comparing the actual state with a predefined state, said apparatus comprising: - a first station for loading a BCBS (back-contact backsheet), with the conducting side facing upwardly, into an empty tray; - a first verification, by means of a first control device, of the position of said BCBS and of the regions onto which a deposition of conducting material is to be performed; - at least one second station for depositing said conducting material in the seats or holes identified in said BCBS; - a second verification, by means of a second control device, of the actual location of the conducting material deposited in said BCBS; - at least one third loading station for the repeatable loading of one or simultaneously a plurality of pre-oriented cells on said previously processed BCBS; - a third verification, by means of a third control device, of the position of said cells on said previously processed BCBS; - a fourth station for loading one or more encapsulating layers in contact with the upper side of said previously processed BCBS and with the previously positioned cells; - a fourth verification, by means of a fourth control device, of the presence of said encapsulating layer; - a fifth station for loading a glass on said previously processed BCBS so as to obtain a structure that corresponds to the structure of said panel, said fifth station comprising at least one heating source that is adapted to allow said one or more encapsulating layers to attach to each other by means of the activation of the adhesives and/or of said one or more encapsulating layers themselves without triggering the polymerization thereof; - a sixth station for tipping said tray, which contains said panel, without offset or relative separation of the individual components contained therein and for positioning said glass in a downward position and for subsequently disengaging said tray from said panel and tipping said emptied tray in said first station and unloading said panel to a lamination unit. - a first station for loading a BCBS (back-contact backsheet), with the conducting side facing upwardly, into an empty tray; - a first verification, by means of a first control device, of the position of said BCBS and of the regions onto which a deposition of conducting material is to be performed; - at least one second station for depositing said conducting material in the seats or holes identified in said BCBS; - a second verification, by means of a second control device, of the actual location of the conducting material deposited in said BCBS; - at least one third loading station for the repeatable loading of one or simultaneously a plurality of pre-oriented cells on said previously processed BCBS; - a third verification, by means of a third control device, of the position of said cells on said previously processed BCBS; - a fourth station for loading one or more encapsulating layers in contact with the upper side of said previously processed BCBS and with the previously positioned cells; - a fourth verification, by means of a fourth control device, of the presence of said encapsulating layer; - a fifth station for loading a glass on said previously processed BCBS so as to obtain a structure that corresponds to the structure of said panel, said fifth station comprising at least one heating source that is adapted to allow said one or more encapsulating layers to attach to each other by means of the activation of the adhesives and/or of said one or more encapsulating layers themselves without triggering the polymerization thereof; - a sixth station for tipping said tray, which contains said panel, without offset or relative separation of the individual components contained therein and for positioning said glass in a downward position and for subsequently disengaging said tray from said panel and tipping said emptied tray in said first station and unloading said panel to a lamination unit.
