1. A drive device for a closure or shutter component in a building, comprising:
at least one motor mechanically coupled to the closure or shutter component;
a direct current electrical energy accumulator element for delivering a direct electrical energy having a direct output voltage;
a solar electrical energy source delivering a solar electrical energy having a direct solar voltage and a solar electric current;
a DC-AC converter that converts said direct electrical energy into an alternating electrical energy having an alternating output voltage;
wherein:
the motor is a low-voltage alternating current electric motor having an effective electric voltage in a range between 50 to 1,000 V;
said direct solar voltage is lower than the effective electric voltage of the electric motor;
the electrical energy accumulator element has a nominal voltage lower than said effective electric voltage and greater than the direct solar voltage delivered by the solar electrical energy source;
a DC-DC charger converts said solar electrical energy of the solar electrical energy source into a DC electrical energy having a DC voltage equal to a recharging electric voltage of the direct current electrical energy accumulator element;
the DC-AC converter supplies said alternating current electric motor with said alternating output voltage.
