NOVELTY - The method comprises: measuring (S200) a temperature of photovoltaic panels including devices for spraying a coolant onto the panels; measuring (S210) the wind speed; activating the spraying of one of the spraying devices when the measured temperature is greater than or equal to a first predetermined temperature value, and the measured wind speed is less than or equal to a first predetermined value of wind speed; and deactivating the spraying of all or part of the spraying devices when the measured temperature is less than or equal to a second predetermined temperature value.    USE - The method is useful for controlling the temperature of photovoltaic panels, which are exposed to wind (claimed), of a photovoltaic system that is installed on a roof of a factory and a house.    ADVANTAGE - The method is capable of effectively controlling the temperature of the photovoltaic panels exposed to wind by spraying the coolant onto the panels in an economical manner, thus eliminating shading effect and preventing the loss of electrical power.    DETAILED DESCRIPTION - The method comprises: measuring (S200) a temperature of photovoltaic panels including a set of devices for spraying a coolant onto the photovoltaic panels; measuring (S210) the wind speed; activating the spraying of one of the spraying devices when the measured temperature is greater than or equal to a first predetermined temperature value, and the measured wind speed is less than or equal to a first predetermined value of wind speed; and deactivating the spraying of all or part of the spraying devices when the measured temperature is less than or equal to a second predetermined temperature value, which is lower than the first predetermined temperature value, and the measured wind speed is greater than or equal to a second predetermined value of wind speed, which is higher than the first predetermined value of wind speed. The activation, the deactivation and/or the spraying pressure of certain spraying devices are controlled according to the measured wind speed. The activating step: is also triggered when a measurement of a physical parameter of the panel is greater than a first predetermined value of the physical parameter; is further triggered if the difference between a temperature measured by the panel and a second ambient temperature measured at the panel and/or a measurement of the temperature of coolant before spraying air is less than a first predetermined difference value; is also triggered when a measurement of ambient air temperature at the panel is higher than the solidification temperature of the coolant; and is also switched if a flow level measuring precipitation of atmospheric water at the panels is less than a first predetermined flow rate value of precipitation of atmospheric water. The deactivation step: is also triggered when the measurement of the physical parameter is less than or equal to a second predetermined value of the physical parameter, which is lower than the first predetermined value of the physical parameter; is further triggered if the difference between a temperature measured by the panel and a second ambient temperature measured at the panel and/or a measurement of the temperature of coolant before spraying air is greater than a second predetermined difference value, which is greater than the first predetermined difference value; is also triggered when the measurement temperature of the ambient air at the panels is less than or equal to the solidification temperature of the coolant; and is initiated if a further flow level measuring precipitation of atmospheric water at the panels is greater than a second predetermined flow rate value of precipitation of atmospheric water, which is higher than the first predetermined flow rate value of precipitation of atmospheric water. The physical parameter is one of: insolation received at the panels; an electrical output produced by the panel; and the current and/or the voltage of operatively coupled electrical panel device. The method further comprises measuring the wind direction. The activation, deactivation and/or pressure of the spraying devices are controlled in the wind direction. The measurement of the temperature of panel consists of performing a measurement above and below the panel. The speed and wind direction measuring step is carried out for a predetermined time to determine the statistical values of the wind. The panels are disjoined by a space in which the spray devices are arranged. An INDEPENDENT CLAIM is included for a device for controlling the temperature of photovoltaic panels exposed to wind.
