Abstract A sun tracking system has been developed in order to receive more solar energy The opto-electronic-tracking mode is likely to be perplexed by weather condition; the time- tracking mode can not avoid the cumulative error or the slow reaction which caused by a big . - database or complicated calculations A new two axes automatic tracking mode which combines clock-tracking and opto-electronic-tracking is presented. Time-tracking mode is designed for the tracking of Azimuth while opto-electronic-tracking is designed for the tracking of Pitching. The 16 . control core is an ATmega SCM The new combined mode overcomes the shortcomings of the two modes. Experiments show that this
