Description

technical field [0001] The invention relates to a solar energy automatic tracking power supply system, in particular to a solar azimuth tracking controller and a tracking method thereof. Background technique [0002] The tracking methods of existing solar automatic tracking controllers can be divided into two types: photoelectric tracking method and timing tracking method. [0003] The photoelectric tracking method is to drive the tracking mechanism to passively track the position of the sun after judging the change of the sunlight irradiation angle by the photosensitive sensor. Its advantage lies in its high tracking accuracy, but its anti-interference ability is poor, it is easily affected by scattered light, there are many misoperations, and it consumes a lot of energy. [0004] The principle of the timing tracking method is to use the law of the earth's rotation of 15° per hour, and use the real clock to adjust the angle of the solar cell module at intervals to track th...

Problems solved by technology

Its advantage is that it has high tracking accuracy, but its anti-interference ability is poor, it is easily affected by scattered light, there are many misoperations, and it consumes a lot of energy

[0004] The principle of the timing tracking method is to use the law of the earth's rotation of 15° per hour, and use the real clock to adjust the angle of the solar cell module at intervals to track the angle of the sun, such as Chinese Patent Publication No. 2562135, published on July 23, 2003, The name of the invention is "micro power consumption timing solar tracking device". This tracking method does not require sensors, has strong anti-interference ability, less misoperation and less energy consumption, but it cannot be adjusted according to the actual local solar movement laws and the processing and installation accuracy of the bracket. It is difficult to achieve high-precision tracking

There are generally disadvantages such as low tracking accuracy or manual correction

[0005] The above two types of sun tracking methods have their own advantages and disadvantages, and cannot fully meet the requirements of high tracking accuracy and strong anti-interference ability
