The present paper discusses the dust effect on the photovoltaics solar panels and proposes the waterless automatic cleaning ranges, applicable to improve the panels output performances in the sahelian region. A comparative study is conducted between the short circuit current and maximal power of the both cleaned and not cleaned polycrystalline solar panels, installed at the Advanced School of Engineering, Dakar. Several automatic cleaning ranges are applied on one panel whereas the other one is never cleaned. The every ten second electrical parameters of the both panels ( short-circuit current, open circuit voltage, power) as well as the consumed current by the cleaning brush are collected with CR800 data logger installed on the experimental platform. The obtained results show respectively a drop in performance of 14.22% and 13.69% for the both short circuit current and power, after four weeks exposure without cleaning. The consumed energy by the cleaning brush is evaluated at 0.9 wh per cleaning in the standard test condition; This correspond to 0.018% of the photovoltaic energy production. These results show an automatic cleaning effectiveness of the photovoltaics solar modules against dust deposits in the sahelian regions.
