AI Technical Summary

Problems solved by technology

[0002] In the prior art, solar power generation devices mostly adopt the method of fixing solar panels, so that the solar panels have only one direction from beginning to end. Since the position of the sun changes from east to west during the day, the solar power of this type of solar power generation device has The panels cannot face the sun all the time, resulting in poor power generation efficiency

[0003] For this reason, people have proposed various improved schemes, trying to allow solar panels to face the sun at all times without artificial movement, so as to achieve the maximum power generation benefit, but the solar power generation in this way in the prior art There are still various problems with the device

[0004] At present, among the devices that automatically track the position of the sun, some use the apparent solar movement trajectory to track. It confirms the current orientation of the sun based on the precise local latitude and longitude and the precise sun trajectory algorithm. It needs to connect to the network to confirm the current time and pass The global positioning system confirms the current latitude and longitude, which not only consumes a lot of power generation, but also complicates the system settings; some use photoelectric tracking, and use photoresistors to compare the light intensity in different directions to confirm the strongest light to confirm the current orientation of the sun. It is technically simpler, and the cost of manufacture and use is also lower. It is accepted by people and is willing to be actively developed.

[0005] Usually, in order to keep the solar panel facing the sun at all times, people use motion to adjust the position and orientation of the solar panel by rotating or swinging. However, only relying on rotation or swinging cannot make the solar panel face the sun directly. In the process, there is also how to move quickly and accurately and adjust to the position and orientation of the sun

[0006] In addition, photoresistors are generally fixed on different sides of the solar panel to detect the intensity of light on different sides. However, due to the long distance between them, the difference in light intensity experienced by them is obvious, which may easily cause differences in measurement. Make it difficult for solar panels to face the sun
