Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a combined solar photovoltaic panel supporting device and method. Background Art

[0002] Solar photovoltaic power generation is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. The independent photovoltaic power generation system requires a battery as an energy storage device, which is mainly used in remote areas without power grids and areas with dispersed populations. The cost of the entire system is very high. In areas with public power grids, the photovoltaic power generation system is connected to the power grid and operated in grid connection, eliminating the battery, which can not only greatly reduce the cost, but also has higher power generation efficiency and better environmental protection performance. Solar photovoltaic panels are generally fixed on the ground through a support frame, but the existing support frame structure is generally fixed, and the tilt angle of the supporting solar photovoltaic panel cannot be adjusted, nor can the position of the solar photovoltaic panel be rotated according to the direction of sunlight. Based on this, the existing patent announcement number CN107544563B discloses a solar photovoltaic panel support device. Although the device can adjust the angle of the photovoltaic panel to ensure power generation efficiency, the device cannot protect itself when encountering extreme weather, which is not conducive to improving its service life.
