Photovoltaic plant

A method for orienting an array of mobile reflection devices of a photovoltaic plant, the photovoltaic plant including a plurality of photovoltaic modules arranged in arrays spaced with respect to each other, and wherein the photovoltaic modules of each array have a first assigned inclination with respect to a reference direction,

• wherein associated to each array of photovoltaic modules is an array of mobile reflection devices set adjacent thereto, and wherein at least one array of mobile reflection devices is located in a space between successive arrays of photovoltaic modules;
• wherein the mobile reflection devices of each array have a second inclination with respect to a reference direction;
• wherein the arrays of photovoltaic modules and the arrays of mobile reflection devices associated to one another include respective front surfaces set facing one another;
• and
• wherein the mobile reflection devices of each array are orientable by variation of said second inclination in order to intercept the incident solar radiation and reflect the latter towards the photovoltaic modules of the associated array,
• the method comprising:
• a first step of detection, within the framework of a time interval having a predetermined duration, the values of one or more physical quantities which are representative of operative conditions of an installation site of the photovoltaic plant,
• a second step of calculation, within the framework of said time interval, of an inclination value of the array of mobile reflection devices as a function of detected values of said one or more physical quantities,
• a third step of comparison of the calculated inclination value with a theoretical and pre-calculated optimal inclination value,
• a fourth step of correction of said pre-calculated theoretical optimal inclination value with said calculated inclination value,
• wherein the first, the second, the third and the fourth steps are repeated along a sequence of time intervals having a predetermined duration.
