Occasionally exposures the southern area of Libya through the period from (February to May) to seasonal winds, which usually carrying dust and sand. So, tiny particles of sand, trees debris, and birds' droppings are accumulating on surface of PV modules, which yield a shading sunlight on modules, the consequence a significant power loss. The area of study classified as rural desert. In particular region a large amount of solar irradiance is abundance over the year. That reason encouraging to adopted clean energy resource on desert environment. This paper investigated a framework of weekly cleaning on PV modules array throughout the period from February to May. The results indicated a significant gradual decrease of power, so frequent weekly water washing maintaining performance losses between (2 - 2.5%). It is important feature of water washing on the modules surfaces deemed more reliable to recover power loss. KEYWORD: accumulation on PV solar module, power losses, weekly cleaning, performance recovery.
