La invención prevé que las conexiones del conducto 2 y de la canaleta 4, se efectúe mediante conductos rígidos para el caso en el que los paneles solares 1 sean fijos, y mediante conducciones flexibles para el caso en el que los paneles solares 1 sean movibles.The invention provides that the connections of the conduit 2 and the gutter 4, be made by rigid conduits for the case in which the solar panels 1 are fixed, and by flexible conduits for the case in which the solar panels 1 are movable.
Por tanto, mediante la invención descrita se consigue un mayor rendimiento de los paneles solares 1, y además su temperatura se regula al nivel óptimo para mantener dicho rendimiento. Para ello la invención prevé la posibilidad de que cuando la temperatura exterior es muy elevada, es detectado por un sensor de temperatura que activa un presostato (no representado) que provoca la inyección del agua a través de la segunda conducción, consiguiendo una mayor refrigeración de las placas solares 1 y manteniéndolas a la temperatura adecuada para permitir su funcionamiento al máximo rendimiento. Therefore, by means of the described invention, a greater performance of the solar panels 1 is achieved, and in addition its temperature is regulated to the optimum level to maintain said performance. For this, the invention foresees the possibility that when the outside temperature is very high, it is detected by a temperature sensor that activates a pressure switch (not shown) that causes the water to be injected through the second line, achieving greater cooling of the solar panels 1 and keeping them at the proper temperature to allow their operation at maximum performance.
