Abstract

The invention relates to a system for cleaning photovoltaic solar panels by means of vibrations, which is based on the use of mini-vibrators for cleaning the panels without any use of water. These mini-vibrators are lightweight and not bulky.

Description

Description : Description:
Procédé d'auto nettoyage des panneaux solaires à base des mini vibreurs. Domaine Technique Self-cleaning process for solar panels based on mini vibrators. Technical area
[001] La présente invention concerne les solutions d'auto nettoyage mécaniques des panneaux solaires. The present invention relates to mechanical self-cleaning solutions for solar panels.
Technique antérieure : Prior technique:
[002] L'énergie solaire est considérée comme l'une des sources d'énergie les plus importantes dans le domaine des énergies renouvelables. Les panneaux solaires génèrent une énergie non polluante grâce à la puissance illimitée du soleil. L'utilisation de ces panneaux a augmenté au cours de la dernière décennie en raison de leurs énormes avantages. Mais, l'un des principaux problèmes qui affectent l'efficacité des panneaux solaires est la couche de poussière et les particules qui s'accumulent sur les panneaux. Solar energy is considered to be one of the most important energy sources in the field of renewable energies. Solar panels generate non-polluting energy using the unlimited power of the sun. The use of these panels has increased over the past decade due to their enormous benefits. But, one of the main issues affecting the efficiency of solar panels is the layer of dust and particles that collect on the panels.
Exposé de l'invention : Disclosure of the invention:
[003] L'objectif de cette invention est de proposer un moyen plus sûr et moins cher de nettoyer des panneaux solaires. L'idée est d'installer des appareils qui vibreront pendant que les panneaux sont tenus inclinés, faisant tomber la poussière au sol par gravité. Ces petits appareils vibrants seront répartis sur la surface des panneaux sur le dos des panneaux. [003] The objective of this invention is to provide a safer and cheaper way to clean solar panels. The idea is to install devices that will vibrate while the panels are held tilted, causing dust to fall to the ground by gravity. These small vibrating devices will be distributed over the surface of the panels on the back of the panels.
[004] Selon une réalisation préférée de l'invention, le mini vibreur est sous forme d'un mini moteur DC entraînant une masse tournante. [004] According to a preferred embodiment of the invention, the mini vibrator is in the form of a mini DC motor driving a rotating mass.
[005] Dans les dessins qui illustrent l'invention, In the drawings which illustrate the invention,
La FIGURE 1 est une vue en perspective du panneau avec des min vibreursFIGURE 1 is a perspective view of the panel with min vibrators
[006] En se référant aux dessins, on verra que Le panneau (1) porte dans son dos des mini-vibreurs (2) sous forme de moteurs commandés et alimentés par une carte électronique, via une batterie. Chaque mini-vibreur pèse un gramme et son diamètre et sa longueur sont 4 mm et 8 mm respectivement. La tension et le courant d'alimentation sont 3 V et 0.2 A respectivement. Referring to the drawings, it will be seen that the panel (1) carries in its back mini-vibrators (2) in the form of motors controlled and powered by an electronic card, via a battery. Each mini vibrator weighs one gram and its diameter and length are 4mm and 8mm respectively. The supply voltage and current are 3 V and 0.2 A respectively.
