Abstract[English]
The invention relates to a device for cleaning solar panels (1), the principle of which is based on an ionic wind combined with an electrostatic force which are applied simultaneously to the dust particles. The device consists of a plasma actuator attached to a wheeled vehicle (9) on the surface of the panel (1). The plasma actuator comprises three electrodes: an ionising electrode (2), an earthed electrode (3) and a static electrode (4). Both the ionising electrode (2) and the static electrode (4) are supplied with the same electric voltage of about twenty kilovolts. The static electrode (4) is a cylindrical tube that applies an electric field so as to detach the dust particles from the surface of the panel (1) by means of an electric attractive force. The assembly made up of the ionising electrode (2) and the earthed electrode (3) produces an ionic wind that easily cleans the dust particles previously lifted by the static electrode (4).[French]
L'invention introduit un dispositif pour le nettoyage des panneaux solaires (1) dont le principe est basé sur un vent ionique combiné à une force électrostatique qui sont appliqués simultanément aux particules de poussière. Ce dispositif est constitué par un actionneur à plasma fixé à un véhicule roulant (9) sur la surface du panneau (1). L'actionneur à plasma comprend trois électrodes : une électrode ionisante (2), une électrode mise à la terre (3) et une électrode statique (4). L'électrode ionisante (2) et l'électrode statique (4) sont toutes deux alimentées par une même tension électrique d'environ vingt kilovolts. L'électrode statique (4) est un tube cylindrique qui applique un champ électrique pour assurer le détachement des particules de poussière de la surface du panneau (1) grâce à une force d'attraction électrique. L'ensemble constitué par l'électrode ionisante (2) et l'électrode mise à la terre (3), produit un vent ionique qui assure facilement le nettoyage des particules de poussière soulevées au préalable par l'électrode statique (4).
