Abstract

The invention relates to a solar automatic tracking and positioning device which comprises a tracking control circuit for controlling a mechanical transmission mechanism and a solar tracking and positioning sensor connected with the tracking control circuit and used for transmitting a solar position signal to the tracking control circuit, wherein, the tracking control circuit is further connectedwith a first direct current speed-reducing gear for adjusting a horizontal angle of the solar tracking and positioning sensor and a second direct current speed-reducing gear for adjusting a pitch angle of the solar tracking and positioning sensor, and the solar tracking and positioning sensor further comprises a comparing light signal receiver which is taken as a comparing light signal and a startsensor array which is taken as a compared light signal. The adoption of the solar automatic tracking and positioning device realizes the high-precision solar tracking without blind zones, leads the tracking device to be capable of identifying the different weather conditions and the daytime situations and improves the reliability of the ability of differentiating the solar position; furthermore,the solar automatic tracking and positioning device can work intermittently according to the sunrise and the sunset, thereby preventing the production of useless work.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to an automatic sunlight tracking and positioning device applied in a solar photovoltaic power generation system. Background technique [0002] Solar energy is a clean and non-polluting renewable energy. Among many solar energy utilization technologies, solar photovoltaic power generation technology realizes the direct conversion of solar energy into electrical energy. It has the advantages of no noise, no pollution, and local utilization. attention from all over the world. The existing photovoltaic power generation system generally installs the solar cell modules in a certain direction, so they cannot always face the sun, so the power generation capacity of the solar cells is not fully utilized. In order to reduce the cost of photovoltaic power generation system and improve the power generation capacity of solar cells, there are two main methods: one is to improve the photoel...
