COOLING METHOD AND SYSTEM FOR PHOTOVOLTAIC SOLAR PANELS

摘要

The present invention relates to a cooling system and method for photovoltaic solar panels. The cooling system and method allow reducing the temperature of the outer surface of photovoltaic solar panels, hereinafter PV panels (2), thereby maximizing their performance and keeping their surface at optimal operating temperatures (about 25° C.) at all times, while at the same time allowing cleaning and eliminating dust and/or fouling residues on said surface, even further optimizing, if possible, the total performance of said PV panels (2).

主权项

1. A cooling system (1) for photovoltaic solar panels (2), of the type that are installed in an inclined position with respect to the horizontal plane for optimal solar radiation capture, characterized in that it comprises:
fluid sprayers (10) arranged on the upper edge of the PV panels (2) for supplying a sheet of fluid over their outer surface, a collection tray (20) fixed to the lower edge of the PV panels (2) to collect and channel the excess fluid coming from said outer surface of the PV panels (2), a drain hose (30) linked at one of its ends to the collection tray (20) to extract the fluid housed therein, a first tank (40) arranged outdoors for storing and cooling the fluid extracted through the drain hose (30), and a second thermally insulated tank (50) that is suitable for receiving the low-temperature fluid coming from the first tank (40) by means of an electric pump (60), said second tank (50) having an outlet duct (51) for recirculating the fluid towards the fluid sprayers (10) of the PV panels (2).
