Description of the Invention: [Technical Field] The present invention relates to a solar panel, and more particularly to a method of controlling a solar panel to automatically face the sun. [Prior Art] Solar panels are traditionally installed at the top of a building or in a well-lit outdoor location, and can generate electricity through the illumination of sunlight to supplement the power required to supply electric appliances for public places or homes. In order to reduce the use of AC power provided by the power company, thereby saving electricity costs. It is also known that the solar panel is generally placed on the top of the building or outdoors, in a state of lying flat or slightly inclined, so that the surface of the solar panel faces upward or obliquely upward, so that the solar panel can receive sunlight for a long time. However, the angle of illumination of sunlight changes with time, resulting in a solar panel that can only maintain a single direction, and it is impossible to obtain sufficient sunlight to be irradiated at any time, resulting in a problem of poor stability of power generation. Therefore, among the more advanced technologies in the workshop, it has been disclosed that a solar panel that can automatically follow the angle of sunlight illumination is mounted on a rack, and a double-axis driver is mounted on the end side of the rack. Driving the frame and the solar panel to perform biaxial oscillation, and controlling the driver according to the angle of sunlight irradiation by a controller to continuously drive the surface of the solar panel to oscillate toward the sun; accordingly, the solar panel can be controlled at any time It can automatically face the sun to get full illumination of the sun. However, the controller of the above-mentioned conventional solar panel only drives the solar panel to a position that is oriented toward the sun according to the sun movement, so that the surface of the solar panel of 200819691 and the sun are not at an angle of 90 degrees, so Ensuring that the surface of the solar panel is accurately oriented toward the sun will also cause poor stability in power generation and will need to be improved. SUMMARY OF THE INVENTION In order to effectively overcome the above problems in the prior art, the surface of the solar panel cannot be accurately oriented toward the sun, resulting in poor power generation stability, and an object of the present invention is to provide a solar panel tracking control method to ensure solar energy. The surface of the panel is kept at an optimum light receiving angle of 90 degrees with the sun, and φ further enhances the stability of solar panel power generation. In order to achieve the above object, the solar panel tracking method of the present invention comprises: planning a plurality of time units in a day in a controller, and presetting a group according to the sun movement trajectory in each time unit. Azimuth (AZIMUTH) and elevation angle (ALTITUDE) for the sun, matched with time units; sensing with a sensor mounted on the shelf of the solar panel and capable of sensing azimuth and • elevation angle Azimuth and elevation angle of the solar panel, and returning the azimuth and elevation angle of the solar panel to the controller; using the controller to compare the azimuth and elevation angle of the solar panel with the azimuth and elevation angle of the current time unit When the azimuth and elevation angle of the solar panel are different from the azimuth and elevation angle of the current time unit, a dual-axis driver drives the solar panel to operate the azimuth and elevation angle of the current time unit; When the azimuth and elevation angle of the solar panel are the same as the current time unit of the square 6 200819691, the angle is the same as the height angle, so that the drive stops driving. The solar panels of the rack operations. In addition, the present invention further includes: presetting a stop time after the last set of time units in the controller; and using the controller to stop the time, causing the drive to drive the solar panel carrier to operate to the azimuth of the first set of time units And height angle. In addition, the present invention also includes: The time unit is planned into 365 groups according to the time of the sun day. The azimuth and elevation angle of each time unit that can face the sun is an azimuth and elevation angle that can control the surface of the solar panel to be at an angle of 90 degrees to the sun. The sensor is disposed on the top, bottom or one end side surface of the rack, and the sensor is an electronic compass or a decoder capable of reacting azimuth and elevation angles (ENCORDER).
