Solar automatic tracking system design

In order to realize the highest conversion rate of solar panels to solar energy, the disadvantages of the traditional solar panels in the fixed installation of low solar energy utilization are changed. Design solar energy automatic tracking system (hereinafter referred to as: tracking system). The tracking system enables direct solar radiation to solar panels at any time in the presence of sunlight. Hereby, the following design proposals are proposed for the mechanical realization method and the electronic automatic control, and the technical indicators are completed.

Mechanical part:

In order to achieve direct sunlight on the solar panels, the solar tracker needs to keep the solar panels supported by the tracker perpendicular to the current sunlight in the light conditions.

1. Its way of tracking the real-time position of the sun is: the two motors synthesize the movement to align the solar panel with the direction of the sun;
2. The tracker implements a 200-degree rotation in the horizontal direction and a 15 - 90-degree rotation in the vertical direction. This range of movement can be installed in areas of the Earth at any latitude and longitude, enabling the purpose of tracking the sun;
3. The vertical direction of the movement can be selected as an electric push rod for DC motor linear drive.
4. Use the worm gear motor drive method in the horizontal direction.
5. As the solar power system works outdoors for a long time, it must be able to adapt to various environmental factors such as lightning, temperature, humidity, wind resistance and salt spray.

Electronic control part:

1. The tracker control system and the solar sensor system are the core of the monitoring system. The detection of the current position of the sun and the control of the orientation of the solar panels are performed to ensure that the solar panels are exposed to vertical solar radiation.
2. Indoor monitoring system and wireless communication system facilitate central control and centralized monitoring, centralized processing of the safety of the tracking system and the operation of normal operation under the influence of different wind speeds; the monitoring system completes the real-time alarm of the abnormal status of each monomer tracker. .
3. When the sun's light intensity is very weak and even if the generated electrical energy cannot meet its own working needs, the control system will enter into hibernation. In the dormant state, it will be powered by a backup battery and will be periodically awakened to detect the intensity of sunlight; when the light intensity reaches When a certain degree of time, the control system will integrate the position and position of the latitude and longitude, the current time and the feedback information of the sensor, and use GPS position tracking to obtain the accurate position of the sun, and convert it into the tracker adjustment information, and change the direction through the motor drive to make the tracker platform The sunlight stays vertical, and the rainy day when the sun is not seen will calculate the current position of the sun based entirely on its latitude and longitude position and current time. Equipped with wind speed detection system.
