<p>The device (10) has an occulting and/or solar protection sheet (12) whose end is secured to a winding tube (13) and opposite end is secured to a load bar (14) carried by a driving unit. The tube is driven in rotation by a direct current motor (18) to deploy or fold the sheet. The motor is supplied with power by an accumulator unit connected to solar photovoltaic modules mounted in series. The photovoltaic modules assure charge of the accumulator unit. A supply voltage variation device of the motor is activated during deployment or folding of the sheet.</p> |
