“…For the energy collection circuit, in addition to efficiency, the main performance index is the lowest condition of the circuit start-up, that is, the lowest input voltage and current. Therefore, this article uses circuitry to test the input minimum voltage and current [7]. From the test results, it can be seen that when the input minimum voltage is 1.2V, in order to ensure normal charging, the input current is 44.2mA, that is, the output power of the solar panel is 55mW, which is very easy to achieve.…”

This paper proposes a design method for tracking solar panel light tracking control system based on microcontroller. The main structure of the system includes light intensity detection module, automatic control module, intelligent information processing module, human-computer interaction module, computer control module and interface circuit module. In this paper, the photoelectric method is used to track the position of the sun, the control process is modeled and simulated in the system. The system is optimally controlled by adding a Kalman filter to the output of the classic PID control. Actual tests show that the input voltage of the circuit is 1.2~5.5V, the maximum charging current is 1.2A, the minimum conversion efficiency of the circuit is not less than 72%, and the maximum conversion efficiency is more than 92%, and the power energy output of the solar panel can be collected and charged even under very weak lighting conditions. Solar energy utilization rate is high.
