Abstract: Composite operating station and method of drilling and fixing for the continuous production of conductive backsheets with an integrated encapsulating and dielectric layer, for photovoltaic panels of the back-contact type. The composite operating station is automated and integrates a plurality of working processes carried out simultaneously in a cyclic sequence. In particular, it is based on a multifunction cylindrical roller which by rotating lays out the film of integrated encapsulating and dielectric material, heats it and presses it on the conductive layer of the supporting backsheet for the purpose of the fixing in a correct position, the roller being provided with openings to enable drilling from outside with a laser device and also to enable the forced suction from inside of the fumes and of the residues by means of an exhaust fan.

Abstract: The present invention relates to a conductive paste or ink, which may be used to form conductive elements on the surface of a substrate, for example an electrode of a solar cell. The present invention also relates to a solar cell in which the upper electrode exposed to the sun is obtained by using said conductive paste or ink and a method for forming a conductive element on a substrate using said conductive paste or ink.

Abstract: Apparatus and method for the automatic assembly of photovoltaic panels with back-contact architecture, the apparatus comprising a series of six stations that are configured in sequence in a carousel with recirculation of trays and a control device, which is adjacent to one or more of the stations, for controlling the correctness of the processes performed, the control device enabling the processing or the mere transit of the tray into the subsequent station by comparing the actual state with a predefined state. If one or more of the controls performed in the transfers between the six stations yields a negative outcome regarding the correctness of the operation performed previously, the control device enables the mere transit of the tray with its content to the subsequent stations until it reaches the first station without undergoing any tipping.

Abstract: A plant and system for the automatic horizontal assembly of photovoltaic panels with front-back-contact solar cells of crystalline silicon, of the type called H-type, the contacting being carried out at a temperature lower than 150° C. also with the pre-fixing of conductive elements onto the encapsulating layer. The plant and system solve the main problems of the conventional stringing systems and provides high production capacity with a precise positioning of the components. The plant is made up of single workstations of the modular type which are arranged sequentially in a linear series, individually equipped according to the specific working process, being adjacent and laterally open to be crossed by the conveying line of the trays containing the panels being worked. After the automatic assembly in the plant, the panels are ready to be rolled in conventional furnaces.

Abstract: Compact apparatus for the semi-automatic horizontal assembly of photovoltaic panels with solar cells, made up of a multi-function workstation in the form of a pilot system integrating multiple working and conveying means which carry out the various operations concomitantly and in a coordinated way. On the sides of the working surface there is the loading zone of the cells, the loading zone of the conductive ribbons and a pair of longitudinal rails which are intended to guide two mobile gantries, which roto-translate above the working surface, from one loading zone to the other, being equipped for the purpose of assembly. In particular, the compact apparatus is versatile in use and allows to obtain already in the experimental laboratory phases the levels of accuracy and control of an industrial system, for the purpose of optimizing the product and the assembly technologies reducing wastes and faults.

Abstract: Architecture system of a local grid made up of at least two single nodes constituting micro-grids, each managed by a self-configurable node controller that is also connected to the controllers of the other nodes and to the single energy generation, storage and consumption elements of its own node, the elements being variable in their configuration and dynamic in their behaviour; the controller also optimizing the energy transfers according to specific management logics of the routine and sub-routine type.
