In general, the pressure distribution on the solar photovoltaic panel is affected by multiple elements, such as the supporting structure, the method of installation, and the surrounding environment. The rational design and optimization of these factors are capable of enhancing the stability and durability of the solar photovoltaic panel.
The pressure at the top is minimal, averaging 100.78 kPa, while at the bottom, it is highest, averaging 102.48 kPa. Additionally, lower pressure is observed on the sides of the solar photovoltaic panel.
From the deformation nature and the strain characteristics, it was also observed that the pressure effects are maximum near to the leading edge on the top portion of the solar panel and gradually decreases towards to the trailing side of the panel.
The results indicate that, under different installation angles, the windward side pressure of the solar photovoltaic panel is generally higher than the leeward side. The leeward side is prone to forming larger vortices, increasing the fatigue and damage risk of the material, which significantly impacts the solar photovoltaic panel.
The front side undergoes relatively even pressure, whereas the central area of the rear side undergoes higher pressure, and the edge region undergoes pressure reduction as a result of swirling winds. These discoveries are of great significance for the design and optimization of the performance of the solar panel.
Therefore, optimal installation methods include installing the panel facing the wind at angles of 30° and 45°, or installing it facing away from the wind at a 60° angle, to minimize the impact of wind load on the solar photovoltaic panel. 1. Introduction
