Abstract:
The present finding refers to a monitoring device configured to monitor information associated with the functioning of a solar panel (12-1, 12-2, 12-3, 12-n). The monitoring device (28-1, 28-2, 28-3, 28-n) comprises connection poles (23a, 24a) that can be connected to electrical connections (21) of the panel and reading means adapted to read the information associated with the functioning of the panel (12-1, 12-2, 12-3, 12-n), such information being selected at least from a group comprising: voltage of the panel, current of the panel, temperature of the panel, pressure and illuminance. The device also comprises a transmitter circuit configured to transmit the information by using the connection poles (23a, 24a), a micro-processor circuit connected to the transmitter circuit and configured to activate the transmitter circuit to transmit the information. The device also comprises an identification circuit connected with the micro-processor circuit (32) and configured to represent a certain identification number of the monitoring device (28-1, 28-2, 28-3, 28-n) associated with the panel (12-1, 12-2, 12- 3, 12-n) such that the micro-processor circuit (32) is adapted to recognize, by means of the identification circuit, a synchronization signal that can be received through the connection poles (23a, 24a) and to activate the transmitter circuit (37), in reply to the acknowledgement of the synchronization signal. The finding also refers to a monitoring system which comprises the device and to a functioning method of the same.
Abstract:
The present invention relates to a process for manufacturing combined solar panels (10) of the photovoltaic and thermal type in which a thermal panel (12) is associated, through a face of the thermal panel (12), to a photovoltaic panel (11), having one or more strings of photovoltaic cells. The process provides for applying a number of glue spots (54, 55) between the face of the thermal panel (12) and the cells, and between the cells and the sheet (15), and for introducing a transparent resin (58) between the face of the thermal panel (12) and the cells, and between the cells and the sheet (15). The disclosed process eliminates the problems deriving from the presence of a material to be cured (polymerised) between the thermal panel and the cells, and between the cells and the sheet, as provided for by the known art. The invention also refers to a solar panel (10) manufactured through the process of the invention.
