The invention relates to an electrical drive for a folding or sliding shutter managing without power supply from the power grid of the building, wherein an electric motor (1) is installed in the panel (10) for transferring a rotary or linear motion to pivotally or longitudinally displaceable panels (10) of the folding or sliding shutter. A rechargeable battery (2) is constructively integrated in the panel (10) for supplying power to the electric motor (1). The rechargeable battery (2) is charged by solar cells (photovoltaic cells) (3a) of at least one solar panel (3) disposed on the surface of the panel (10). |
