Comparative Performance Analysis of PV Module Positions in a Solar PV Array Under Partial Shading Conditions

Abstract

The irradiation intensity is the primary catalyst for energy production in photovoltaic (PV) systems. Nevertheless, it alleviates partial shading (PS) by inhibiting power production, primarily in habitable metropolitan areas, owing to surrounding objects or high soiling rates, particularly in dry and semi-arid climates. Hence, the PV module's location, orientation, and tilt angle significantly affect its performance and shorten its durability. Thus, this study undertakes a benchmark analysis of the two distinct panel positions' performance using PSIM and MATLAB software simulations and an actual practical test. A visual inspection of a solar power plant in Morocco's Green Energy Park is the origin of the survey concept; it observes that the soil density consistently covers certain PV panel spots. In this context, the solar energy data of an intelligent home deployed in the earlier-mentioned research platform has been deployed to emulate the performance of future buildings challenged with various obstacles. Therefore, the roof-mounted PV system satisfied the home's energy demands. In the first scenario, the PV module is in portrait mode. In the second case, they are in landscape orientation. The findings of this investigation demonstrate that standard PV panels produce more power when arranged in a landscape configuration than in a portrait configuration, exhibiting a discrepancy of up to 1010 Wh for a modest PV system. Finally, this study suggests appropriate orientation and design recommendations for standard and advanced solar modules, mainly those deployed in arid and heavily populated urban regions featuring severe shading constraints.

Modeling and Simulation of Photovoltaic Panel Using Simulink and Proteus Simulation

“…2. Which is based on a single-diode that contains a photocurrent Iph , a diode D, a parallel resistor Rsh, and a series resistor Rs [3,4,5,6].…”

“…Today, street lighting, battery chargers, and connected grid power systems all use solar energy as their primary energy source. Solar radiation, cell temperature, position in relation to the sun and shadows, and cloudiness are the primary elements that influence the PV cell's output voltage VpV and current IpV values [4,5,6]. A PV array is built up of PV modules, which are fixed and connected collections of PV cells.…”

Two-Stage Grid-Connected Frequency Regulation Control Strategy Based on Photovoltaic Power Prediction

“…In the context of the global energy transition, renewable energy sources such as photovoltaic power systems are connected to the distribution network to participate in its operation [1][2][3]. With the emergence of a high proportion of power electronic devices such as PV grid-connected inverters, the number of conventional generating units has been drastically reduced and the resulting multiple rotational inertia no longer exists, prompting an increase in grid frequency shifts and even collapses [4,5].…”
