In order to increase the photoelectric conversion efficiency of a double axis tracking system in dish solar thermal power generation, a tracking method combining photoelectric tracking, which directly tracks focus spot, and memory tracking was used. This method was able to improve the tracking efficiency and reduce costs on research and development. Designs of hardware and software of a tracking control system were introduced in detail. The results of experiments show that this system can work well under any weather. This design provides an alternative approach to improving the accuracy of auto-tracking of dish solar power.
