This research is made into the controller with single chip 8052 microprocessors and tested. On a sunny day basis, the experiment results show that the full-time generation of the tracking concentrator system is 3.09 times of the full-time generation of the fixing system, the power consumption of the stepper motor accounts for 2.2% of the full-time generation of the tracking concentrator system. The performance of the Two-axis Sun Tracking of Concentration PV System is shown satisfactory. |
