Described herein is a water-based cooling system applied to photovoltaic panels for reducing the loss of power caused by the increase of the working temperature thereof. The system includes a sandwich-like assembly for a photovoltaic panel comprising an acrylic plate located at the rear portion thereof which is joined together to the panel frame, and hermetically sealed. Said plate, which is located on a surface at 45 degree, receives water from a potable water reservoir through a leading pipe, this latter element comprising a device locate at the end portion thereof for controlling the water level, thus regulating the water inlet. The panel is cooled by the water flow, thereby resulting in an optimum performance and power generation; the electrical power generated by the photovoltaic panels is stored in batteries so as to be used when required. The water flow is regulated by a sensor, a PIC and a valve when water has reached a specific temperature; the water exiting the panel is stored in a thermal container so as to be subsequently used for common sanitary purposes.
