![]() According to an article published by The Economist, the Gulf region has the most toxic air in the world. Dust deposition in most parts of the kingdom of Saudi Arabia has an impact on solar panel energy production and use. ![]() Cleanliness and clarity must be kept throughout every centimeter of the PV panel to produce the desired power. In addition, a film of dust or a microscopic debris can block the photons from the panel, and that can affect the productivity of the solar panel. Those types of issues have limited the solar from becoming a primary utilized source of energy. ![]() All these contaminants will be accumulated on the surface of the panel which leads to a reduction in the absorptivity of this surface for solar radiation. Also, the PV panels can be exposed to other contaminations from trees, birds’ dropping and other pollutants from the surrounding environment like smoke, building constructions. In this work, designing and manufacturing a mechanism to clean the PV system has been carried out in Medina city which exposed to dust during the windy days. Dust and other external pollutants can block the photons form the solar panel which will effectively reduce the output power. Being under this weather condition will cause the dust and sand to accumulate on exposed surface of the solar panel. Medina region is classified as a desert environment. Some companies have produced machines to clean solar panels, while other companies have developed smart robots for this purpose. Some companies provide a monthly cleaning service, and it costs 43 SR per panel a month for two meters by one-meter panel.Ĭlearly, the PV panels in Medina region are needed to be cleaned regularly due to the dusty weather, and for that, the process will be very costly. The average cleaning price per panel is around 20 SR per panel for one-time cleaning. Although many companies provide a cleaning service to regain the desired potential of the panel, the services they offer are traditional ways to clean and very expensive. If the panels leave without cleaning, the output power even more, therefore cleaning the photovoltaic panels frequently is essential to get the necessary power output from these panels.Ĭleaning the solar panels passed through several stages starting from using workers to do manual cleaning. Dust accumulation on the PV panel surface leads to a reduction in energy output and decreases the efficiency of the solar system. The problem in the PV systems is that these panels get dirty over time. ![]() The PV panels are working on an atomic scale to produce the power, the installation, maintenance time and costs can play a significant role in the efficiency of the energy that comes from the PV panel. The PV cells made of different semiconductor materials connected together in the form of chains to form larger units known as modules or panels. Solar Photovoltaic (PV) panels convert the sunlight to electrical energy. Solar energy is one of the most promising sources to replace the dependency on the conventional energy sources. Therefore, it is necessary to seek for non-conventional energy resources like renewable energy. Medina, one of the most important cities in Saudi Arabia that lies in the west region, has witnessed a high energy demand last ten years. The country is strategically located near the Sun Belt, in addition to open and empty desert that may accommodate infrastructure for solar power systems. Saudi Arabia has one of the world’s highest solar irradiation in the world. Problem of poor performance of the photovoltaic cells in areas that experienceĭusty environment and external pollutants. Work can be considering as a promising and efficient system to solve the Has been reported as 35% and 42% for both cases. The input power of 460 W/m 2, the estimated efficiency was 12.6% and 7.3%įor clean and dusty panel respectively. At input power of 805 W/m 2, the efficiencyįound to be 13.78% for the cleaning panel and 9% for dusty panel, whereas at Performance has been evaluated for both clean and dusty panel at variable The clean and dusty module performance has been conducted. Strength system components were examined and found to be stable and reliable.Īlso, the performance of cleaning system evaluated and comparison between The proposed cleaning system can be worked for long time efficiently. Jet to remove the accumulated dust and other dirt from solar panels surface. This system powered by the PV module itself.įull cleaning system has been designed and tested utilizing a wiper and water This work aims to design a cleaning system for the solar PV panels under
