Abstract
Solar energy is one of the most important sources of renewable energy, clean and environmentally friendly. The amount of energy produced by photovoltaic cells at 46.9% worldwide depends mainly on the amount of radiation that reaches solar cells. There are many factors that depend on the amount of radiation that reaches the solar cells for better performance. The environment is one of these factors, which plays a key role in performance. Solar panels are exposed to dust, which adversely affects performance efficiency. For example, in Saudi Arabia, a decrease of 32% was reported due to the accumulation of dust on the PV system. To solve this problem, there was a solution to get rid of accumulated dust on the photovoltaic panels using cleaning. Manual cleaning takes a long time and may have a negative impact on photoelectric performance. Therefore, many techniques used for dust removal and cleaning have been studied by knowing the advantages, disadvantages, working mechanism and efficiency of each of these techniques. The mechanical method was chosen and applied in practice. Through the work of a robot mechanical cleaning the PV every 24 hours to get rid of accumulated dust. After the implementation of this project we found that this method is one of the best ways to be used in the cleaning of PV in Palestine
