A solar tracker and solar anti-tracking method

Abstract

The invention provides a novel solar energy anti-tracking method. At sunrise, working and stopping of anti-tracking motion are controlled according to the criterion whether an upper induction point and a lower induction point of each eastern sensor of trackers except a easternmost tracker are sunkissed or not, and at sunset, the working and the stopping of the anti-tracking motion are controlled according to the criterion whether an upper induction point and a lower induction point of each western sensor of trackers except a westernmost tracker are sunkissed or not. The invention further provides a novel flat homotaxial solar energy tracking system which comprises three or more solar energy trackers. Each solar energy tracker comprises two stand columns, four sensor assemblies, a solar cell panel mounting rack, a rotary driver, a bearing, a solar cell panel aluminum frame and a solar cell panel and further comprises a hoop, a right-angle connecting piece and an M8 erection bolt, wherein the hoop, the right-angle connecting piece and the M8 erection bolt play a role in connection. The novel flat homotaxial solar energy tracking system and the anti-tracking method are suitable for different installing places and installation gaps among different tracker arrays, and not affected by installation errors.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a solar tracker and a solar anti-tracking method. Background technique [0002] The solar tracking system is a mechanical and electronic control unit system that optimizes the use of solar energy in the process of photothermal and photovoltaic power generation to improve photoelectric conversion efficiency. During the solar tracking process, if the solar panel is kept facing the sun at any time, and the sunlight irradiates the power device of the solar panel vertically at any time, the power generation efficiency of the solar photovoltaic module will be greatly improved. But at the same time, if the solar panels are allowed to keep the sunlight vertically incident, when the incident angle of the sunlight is small, such as in the morning and evening, part of the solar panels will be blocked by the adjacent panels closer to the incident direction of the sun. The ...

Problems solved by technology

[0004] When anti-tracking the solar energy according to the above-mentioned anti-tracking method, there are the following problems: (1) different installation locations, the angle of the incident angle of sunlight, the distance between the tracker arrays, and the size of the tracker due to the difference in latitude and longitude and installation height and other parameters are different, so the existing anti-tracking operation parameters cannot be used in the same place; (2) The anti-tracking method requires a large number of parameter calculations, so the ability and capacity of the computing chip of the controller must be (3) The current construction accuracy and installation accuracy are difficult to meet the accuracy requirements of the existing anti-tracking calculation, so the compensation coefficient is added to the current anti-tracking calculation method, and this will greatly reduce the cost of the system. Reduced power generation efficiency
