“…Most of the Middle-East countries' areas are deserts, where a high frequent of dust storms and regularly accumulated dust cleaning directly after each one [7] such as in Iraq [8]. Qatar [9], Iran [10], Jordan [11], Saudi Arabia [12]. The weakness of many existing dust removal techniques has been demonstrated by various studies in the last two decades.…”

The dust accumulation is an undesirable phenomenon in a solar plant environment. The dust removing procedures were using traditional techniques which are led to more loss in power especially in desert areas. Additionally, most of the cleaning techniques are designed according to the concept of vanquishing the adhesive force of dust particles by adding a harmonic excitation force. This force may produce damage to the solar panel. Therefore, the main objective of the current study is to simulate a traditional solar panel model BSP32-10 with ANSYS software throw an additional external force (2, 4, 6, 10, and 15 Newton) throws six mode shapes and verified experimentally. Deformation values of solar panel surface increase with an increase in excitation force, and not exceed the natural frequency deformation, with average values from 0.07 to 1.5 mm, while 94% of these results are close to experimental work during verification action. Middle position of the solar panel for excitation force on the solar panel in the dust removal concept is the best position.

“…From a commercial perspective, every solar photovoltaic (PV) power plant developer intends to extract the maximum amount of energy from the available space of land or rooftop [3]. Many factors play a role in optimizing the maximum generation from the installed capacity [4], [5]. The selection of topologies of the PV systems along with grid configurations play a role in the overall power losses [6].…”

With recent steep decrement of Photovoltaic (PV) module prices, many utilities around the world are investing in large scale solar PV power plants to meet their energy needs. Countries with an ample amount of deserted areas tend to utilize it for the purpose of energy generation. This article reviews two equal power rated solar PV power plants with similar environmental conditions located next to each other with similar installed equipment but different output energy generation. Various factors affecting the generation of these technically similar power plants such as PV module tilt angle, inter row spacing, annual degradation effect, the negative temperature coefficient of power and other causes are explored evaluate the performance along with the assessment of reasons for deviation in the performance. The energy output trend and the percentage difference for each month for a complete year are graphed for analysis with and without considering the degradation effect to give a level playing field for both the PV plants under review. The efficient design of tilt angle, inter row spacing for the area of installation with the help of sun charts and shading occurrence diagram, is of utmost importance to maximize the energy yield. Any laxity in designing these parameters result in heavy financial losses to the investor which multiply over the life cycle of the project. Similarly, an improved and proper design can increase the energy output and have a positive impact on the financial savings of the investor which in this case is USD 0.85 million per annum. INDEX TERMS Solar PV technology, inter row spacing, solar design, tilt angle, energy output, very large scale photovoltaic (VLS PV) systems, ground cover ratio (GCR).

“…Several researches have been carried out to study how environmental effects interfere with the variation of the amount of dust deposition in PVs and to develop functions to quantify the deposition related to other variables. Researches such as those from Saidan, M. et al [2] and Gholami, A. et al [3] have developed experiments to relate the decay of PV yields with the time of exposure to the environment and the deposited dust density. In a similar study Beattie, N.S.…”

Resumo: O uso de sistemas energia solar fotovoltaica cresce consideravelmente em todo o mundo. Pesquisas mostram que os módulos fotovoltaicos (FV) são consideravelmente afetados pela existência de poeira e sua deposição nas superfícies dos módulos, levando à redução da eficiência do sistema. Este trabalho tem como objetivo desenvolver um estudo, utilizando a Dinâmica dos Fluidos Computacional (CFD), sobre o uso de jatos de ar para promover o arrasto das partículas de poeira, removendo-as da superfície de módulos. Um modelo foi desenvolvido utilizando uma análise Euleriana, baseada em parâmetros físicos, a fim de descobrir a velocidade do ar para promover o arraste da poeira. Através do uso do software ANSYS CFX 17.1, foi possível realizar a montagem e simulação do modelo e adquirir dados importantes.
