Solar panel tracking control method

Abstract

The invention discloses a solar panel tracking control method comprising the following steps: a, adopting a computer and building a coordinate system; b, arranging a spherical hinge to support the central position of the bottom surface of a solar panel, respectively arranging an assistant strut bar on the negative terminal of the east-west direction and the north-south direction of the solar panel, respectively arranging a vertical rack on the positive terminal of the solar panel, and arranging two motors to respectively drive one gear to be meshed with two vertical racks, wherein two motors are both connected with the computer and controlled by the computer; c, shooting the sky by imaging equipment; d, analyzing the shot image, and obtaining the coordinate position of the lightest point in the coordinate system; and e, according to the coordinate position of the lightest point in the image, calculating by the computer and controlling two motors to drive the solar panel to rotate to the position just against the lightest point in the sky by the gear and the rack. The invention has the advantages of accurate tracking and high reliability.

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a solar panel tracking control method. Background technique [0002] In the current systems that use solar energy for photovoltaic power generation and solar water heating, the installation direction of solar panels is generally fixed according to the local sunshine conditions, so most of the time the sun's rays are not completely perpendicular to the light-facing surface of the solar panels. The utilization and conversion rate of solar energy is low. In order to improve the absorption and conversion efficiency of solar panels, some methods and technologies are used to automatically track the direction of the sun, so that the sun's rays are as vertical as possible to the solar panels, and these technologies can be roughly divided into two categories. One is to use photoresistors, photodiodes, light sensors, etc., to cooperate with corresponding signal processin...

Problems solved by technology

However, this type of method has the following problems: the accuracy of the perceived sun direction is not high, the tracking is not accurate enough, and the solar panels must be returned at night, etc.

For example, the active solar tracking method and device announced in Chinese Patent No. 200910100808.6 and the toothed belt transmission group synchronously tracking solar automatic tracking device based on the orbit of the earth and the sun announced in 200910086319. Tracking, the problems of this type of method are: first, the sun’s irradiation angles are different in different places, so different regions must record different sun trajectory information and operate according to different information, and the workload is heavy; It is more complicated; the third is that the sun's rays do not have obvious directivity in cloudy and rainy days, but the motor system still consumes power to work
