Photovoltaic sun tracking system

Abstract

The invention provides a photovoltaic sun tracking system which comprises photovoltaic sun tracking devices, at least one connecting member and a driving member. Each photovoltaic sun tracking devicecomprises a cell panel fixing part whose bottom is fixedly provided with a main shaft, a transmission part and at least one column provided with a bearing, the main shaft is arranged in the bearing, and the transmission part obtains power and rotates and moves in the bearing, the transmission parts of the photovoltaic sun tracking devices are connected via the connecting member and can transmit power, and the driving part is connected with the transmission part of any photovoltaic sun tracking device and can output power. The photovoltaic sun tracking system includes the photovoltaic sun tracking devices, power can be transmitted to other photovoltaic sun tracking devices via the connecting member by arranging the driving part in only one photovoltaic sun tracking device, thus, the whole photovoltaic system can track the sunlight incident angle, the driving structure is simplified, the place adaptability is improved, and the production and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of operation and maintenance of photovoltaic module systems, in particular to a photovoltaic sun tracking system. Background technique [0002] With the development of clean energy, photovoltaic modules have been used more and more. As the core components that convert solar energy into electrical energy, the installation and placement of photovoltaic modules is very important. In photovoltaic power generation systems, in order to improve the photoelectric conversion capability, photovoltaic modules are generally placed on fixed supports facing the direction of sunlight. [0003] Since the power generation efficiency of photovoltaic power generation is greatly affected by the angle of sunlight, making the orientation of the solar cell panel move with the angle of sunlight can effectively improve the photoelectric conversion efficiency of the solar cell panel. In the existing tracking devices, a driving mechanism is ge...

Problems solved by technology

However, due to the large number of components in the photovoltaic tracking device, each panel is equipped with a driving mechanism to track the sun separately. For the laying of large-scale photovoltaic modules, not only the cost is high but the failure rate is high, which is not conducive to the promotion and utilization of photovoltaic power generation projects.
