The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the no-load voltage of the photovoltaic generator, determining a numerical value on the basis of the no load voltage, corresponding to the no-load voltage reading, and comparing the predetermined numerical value with at least one reference threshold value. When the predetermined numerical value corresponds to a value range limited by at least one such reference threshold value the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.
