Controlling dynamic systems by measuring the no-load voltage of a photovoltaic generator

A method of controlling an apparatus based on sunlight, said apparatus being comprised of a dynamic system having a first configuration and a second configuration, a photovoltaic generator connected to said dynamic system, a battery connected to said dynamic system and said photovoltaic generator so as to store electrical energy supplied by the photovoltaic generator and to supply electrical energy to said dynamic system, and a means for controlling said apparatus being connected to said dynamic system, said photovoltaic generator, and said battery, said method comprising the steps of:

• setting a reference threshold value corresponding to a first value range and a second value range, said first value range being associated with said first configuration of said dynamic system, and said second value range being associated with said second configuration of said dynamic system;
• electrically isolating said photovoltaic generator from said battery;
• taking a no-load voltage reading of said photovoltaic generator so as to determine a numerical value based on sunlight exposure of said photovoltaic generator;
• comparing said numerical value to said reference threshold value;
• and
• based upon the comparison result, setting said dynamic system in said first configuration or in said second configuration, wherein said dynamic system is placed in said first configuration based upon the numerical value based on sunlight exposure of said photovoltaic generator being within said first value range, and wherein said dynamic system is placed in said second configuration, differing from said first configuration, based upon the numerical value of the sunlight exposure of said photovoltaic generator being within said second value range.
