Abstract

The invention discloses a two-degree-of-freedom photovoltaic power generation device for automatically tracking sunlight and a tracking method. The problem of single position of the battery panel is overcome as the solar panel is capable of tracking the position of the sun. At the beginning, the device is initialized, a photosensitive element provides the collected data to a single chip, the single chip receiving the data signal runs the program and controls a first stepping motor and a second stepping motor that are electrically connected to make the worm and the second worm rotate to drive the transmission main shaft to rotate, so that the solar panel rotates and can receive the maximum illumination. The stepping motor and worm gear set used by the invention for angle adjustment is capable of realizing precise angle control and self-locking of the corresponding rotation direction, and preventing the orientation of the solar panel from being arbitrarily changed due to external force factors. The photosensitive member of the invention is capable of accurately determining the direction of the sun light and automatically adjusting the orientation of the solar panel to be the same asthe direction of the sunlight.

Description

technical field [0001] The invention relates to a solar photovoltaic power generation technology, in particular to a two-degree-of-freedom photovoltaic power generation device and a tracking method for automatically tracking sunlight. Background technique [0002] Solar photovoltaic power generation devices play an important role in light energy generation, especially in the field of new energy. The installation height of photovoltaic devices is suitable, and the maximum light intensity within the appropriate range can ensure the maximum power of photovoltaic power generation devices to convert light energy into electrical energy. thereby obtaining the most energy. However, the traditional photovoltaic power generation device receives sunlight at a fixed position. With the movement of the sunlight, the solar panel cannot automatically track the sunlight, especially when the direction of the sunlight is opposite to that of the light energy receiving device. It can't work, wh...
