Dual-Mode Solar Tracking Controller
For the current solar tracking controller’s poor immunity, poor tracking accuracy and the traditional sensor‘s form single issue, this paper propose a dual-mode solar tracking system which is based on PLC (Programmable Logic Controller). The system combined the fixed trajectory rough tracking with the photoelectric sensor accurate tracking effectively, and improved the controller’s photoelectric sensor tracking mode. By comparing the results of experiments, it shows that the improved tracking controller can achieve tracking accuracy highly. So it can promote the utilization of solar energy.
