Many factors affect the performance of photovoltaic (PV) panels such as dust accumulation and overheating. Dust accumulation on PV panels can obscure the solar radiation and reduce the efficiency of the panels dramatically. Heating of PV panels due to excessive solar radiation and high ambient temperature reduces the efficiency of the panels significantly. The main objective of this study is to solve the problems of dust accumulation and overheating using the minimum amount of water and energy. These two issues are tackled by developing a system that can clean the PV panels from deposited...

Zu den Faktoren, die den Wirkungsgrad von PV-Paneelen beeinflussen, gehört die Überhitzung. Für jeden Temperaturanstieg von 1°C sinkt der Wirkungsgrad des PV-Panels um 1 %. Ziel dieser Forschungsarbeit ist die Entwicklung neuer Techniken zur Verbesserung der Leistung von Photovoltaik (PV)-Paneelen. Es wurden zwei Technologien vorgeschlagen, um die Leistung der PV-Paneele zu verbessern. Die erste Technik ist die Beschichtung des Panels mit Öl, um die Absorptionsfähigkeit der Paneloberfläche zu verbessern. Es wurde festgestellt, dass die Beschichtung der PV-Paneele mit einer 10 mm dicken...

La surchauffe est l'un des facteurs qui affectent l'efficacité des panneaux photovoltaïques. Pour chaque augmentation de 1°C de la température, l'efficacité du panneau PV diminue de 1%. L'objectif de cette recherche est de développer une nouvelle technique pour améliorer la performance des panneaux photovoltaïques (PV). Deux technologies ont été proposées pour améliorer la performance des panneaux PV. La première technique consiste à enduire le panneau d'huile afin d'améliorer l'absorptivité de la surface du panneau. Il a été constaté que le revêtement du panneau PV avec...

One of the biggest challenges of the world is to find sufficient energy for the future. Solar energy is the largest and most abundant renewable energy. However, the performance of a solar photovoltaic (PV) panel is significantly reduced because of the dust deposition on its surface. This work is concerned with the numerical investigation of air flow and dust deposition behavior around a ground mounted solar PV panel using computational fluid dynamics (CFD). Moreover, installing vortex generators (VGs) as a passive cleaning method on the PV panels is introduced and analyzed. Simulations are...

Among the factors affecting the efficiency of PV panels is the overheating. For every 1oC rise in temperature, the efficiency of the PV panel drops by 1%. The objective of this research is to develop new technique for improving the performance of Photovoltaic (PV) panels. Two technologies were proposed to improve the performance of the PV panels. The first technique is coating the panel by oil in order to improve the absorptivity of the panel surface. It was found that coating the PV panel with a layer of Labovac oil of a thickness of 10 mm, improves the efficiency of the PV panel by more...
