Problems solved by technology

[0004] However, in the actual process, the researchers found that the sunlight received by most of the solar panels in the large-scale biaxial photovoltaic generator set will be blocked by a small number of solar panels in a certain period of time, which reduces the overall efficiency of the photovoltaic generator set.

Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] like figure 1 As shown, a dual-axis photovoltaic generator anti-tracking method includes the following operating steps:

[0036] a) Arrange a number of photovoltaic generators in an array, so that the number of rows and columns and the distance between adjacent photovoltaic generators are equal, and the row spacing is determined to be h 西 , the distance is h 北 , and determine the length of the solar panel as a and the width as b.

[0037] b) In a day, the dual-axis photovoltaic generato...

Abstract

The invention discloses an anti-tracking method of a double-shaft photovoltaic generator. Through the variation of the solar altitude and solar azimuth in one day, the factors causing a decrease in electricity generation amount of a solar panel after sunlight is shielded are taken into full account, and the tracking trajectory of a tracker is especially optimized so that the double-shaft photovoltaic generator is in a tracking state and an anti-tracking state at different stages. After measurement, the electricity generation amount of the double-shaft photovoltaic generator with the anti-tracking function is improved by 3-5 percent than that of a double-shaft photovoltaic generator without an anti-tracking function.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to an anti-tracking method for a biaxial photovoltaic generator applied in a large-scale photovoltaic power generation system. Background technique [0002] Solar energy has excellent properties such as cleanness, no geographical limitation of resources, and inexhaustibility for human beings, so it has attracted more and more attention. Among them, solar photovoltaic utilization, that is, the technology of directly converting sunlight into electrical energy through photovoltaic devices, is particularly eye-catching. [0003] At present, the manufacturing technology of domestic biaxial photovoltaic solar power generation system has become increasingly mature, and its production cost has been greatly reduced due to the development of concentrating technology and the improvement of silicon cell manufacturing technology. Photovoltaic power generation has the ...
