Description

Technical Field

[0002] Photovoltaic power generation refers to the process of converting solar energy into electrical energy through a photovoltaic power generation system. Photovoltaic panels are placed in direct sunlight areas through placement racks. Since the solar altitude angle changes continuously in the same location throughout the day, the angle needs to be adjusted to increase power generation and improve the photovoltaic power generation efficiency of the device. At present, photovoltaic panels are generally placed on the placement racks first, and then the photovoltaic panels are fixed. Then the photovoltaic panel placement racks are manually adjusted in angle. The workload of manual angle adjustment is large. Existing photovoltaic panel placement racks can generally only fix the photovoltaic panels and then flip them up and down or rotate them after the angle is fixed. The accuracy is low, and the photovoltaic panels cannot always be kept in the inclined position with maximum solar radiation. The photovoltaic power generation, power generation efficiency and scope of application are relatively limited.
