Numerical Simulation of a Ground-Supported Solar Panel PV Array Subjected to Periodic Flow

Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation. A widely used approach to mitigate the effect of PS is dynamic reconfiguration, where, the interconnection of PV panels is modified according to the shading condition to achieve maximum output. Dynamic reconfiguration techniques use sensors, a programmable controller, and a switch matrix for optimal operation. However, they have drawbacks such as system complexity and scalability issues. For instance, reducing the number of switches limits the flexibility of the reconfiguration algorithm. In this paper, an automatic dynamic reconfiguration scheme is proposed in which PV panel irradiation activity controls the interconnection of switches, without the need for a programmable controller. A modular building block is proposed from which easily scalable PV arrays can be constructed in a hierarchical manner. Experimental and analytic results have verified the effectiveness of the proposed reconfiguration scheme.

“…It is possible to increase the energy intensity and, as a consequence, the temperature of the source of the heat by focusing sunbeams [4][5][6].Because this is a technology that can be used for both electrical and thermal conversions, and because it employs a completely clean and infinite source of energy, it is obvious that this is a solution that can assist to reduce the amount of fossil fuel that is utilized [5][6][7][8]. A mirror arrangement is used in all methods of concentrating solar power (CSP) to focus sunlight onto a single target and convert it to heat [9].…”

Solar energy has piqued people's curiosity since the dawn of civilization, and the technology for harvesting it has advanced at a rapid pace. The development of technology to increase the efficiency of the solar system is of critical relevance due to the energy difficulties that civilization has been facing. Scientists have used the solar concentrated system for several years since it allows for the concentration of solar energy into a concentrate, allowing for a significant increase in energy efficiency. A parabolic dish setup is described in this article as a dish-shaped concentrating collector that reflects solar energy onto a receiver located at the focal point. This concentrator is set atop a framework with assumption of a two-axis tracking system to track the sunlight. Typically, the acquired heat is utilized directly by a heat engine constructed on the receiver that travels with the dish. Typically, the acquired heat is utilized directly by a heat engine constructed on the receiver that travels with the dish. The suggested dish could achieve very high temperatures and might be utilized in solar reactors to generate high-temperature solar fuels. Even though dishes are seldom utilized commercially for power production, engines are now favored for power conversion. Consequently, the purpose of this study is to explain the benefits of this technology in a world where fossil fuel usage is a genuine issue that society must address.

“…In the year 1839, Edmond Becquerel made the discovery that led to the development of the photovoltaic (PV) system. Because PV panel do not produce any pollutants, they are considered to be a kind of sustainable energy [10][11][12]. As a result of the factors that were discussed earlier, solar panels are currently utilized in the majority of countries throughout the world as a primary source for the generation of electrical energy.…”

Abstract. From the beginning of March to the end of August 2022, research is conducted to determine how sensitive monocrystalline solar modules are to variations in environmental factors such as dust and high temperature buildup as well as cloud cover in Kirkuk's environment. In order to evaluate how different environmental factors, affect a solar photovoltaic (PV) module, an experiment was conducted using three solar modules that were identical in all respects. The modules are cleaned on a regular basis in the morning in order to monitor the effect that the accumulation of dust will have on the surface of the dirty module during the months of April and May. According to the findings, the collection of dust has a significant impact on the daily energy yield of the module that has not been cleaned. On the other hand, this impact lasts for a very long time. The influence on the cloud cover can be seen very immediately. Because of this constraint, solar photovoltaics (PV) are an unstable source of power for remote devices, which strongly emphasizes the difficulties associated with frequently cleaning the surface of the module.
