| dc.description.abstract | Solar energy is typical green energy. Solar photovoltaic power generation systems rely on the absorption of sunlight to generate electricity. Generally, the light input ratio per unit area of solar photovoltaic panels is related to the angle of sunlight irradiating the system. Therefore, the tracking system is often used to maintain relatively the optimal irradiation mode can improve the overall power generation efficiency. However, the overall construction cost of a high-precision dual-axis solar tracking system is too expensive, and it is often used with high-power solar cells, which is not popular. Therefore, to improve the power generation efficiency of the monocrystalline silicon cell module using the tracking system, it is necessary to consider setting up a simple tracking system with a lower cost.
At present, it has practical applications at home and abroad, and can obtain higher cost performance than ordinary fixed monocrystalline silicon battery systems. Therefore, this study aims at a specific simple solar tracking system and analyzes and improves it by finite element analysis to help develop a more cost-effective solar photovoltaic power generation system. This simple tracking system, its module platform is a chessboard-type structure, and the operation method is to pull the four corners of the platform to chase the sun by steel cables. After research, it was confirmed that the platform structure of this system must be improved against wind pressure, and the spring deflection would cause the steel cable to rub against the coiling drum, so there is room for improvement. We use the simulation tool of the wired element method to analyze and adjust static parameters. The results show that by increasing the size of the central circular tube and rectangular tube, the wind pressure of the structure can be increased from 52kgf/m² to 105kgf/m². The combination position of the collocation composition and the steel cable is changed from the four corners of the platform bracket to the middle of the four sides, and the deflection can be reduced by lowering the collocation composition.
After the improved design, the ability to resist wind pressure is significantly improved, and the problem of the coiling drum of the steel cable is solved, which will reduce the maintenance cost, improve the proper rate, and become a more stable and reliable product for the tracker.
