Solar energy density is low, only in the light of the sun vertical to irradiate on the solar battery board, can maximum efficiency in the use of solar energy. The existing technology of solar tracking apparatus is tracking of single direction of the sun, solar energy utilization efficiency of the bottom, this paper studies a suitable technology to track to track the sun in full range, with its the automatic judgment of real-time tracking solar irradiation intensity. Described the structure scheme, improved controller design, parameters of the experimental method, ensure the mechanism movement stable, accurate, experiments show that, this system has superior performance, low cost, high benefit, solar energy collection, novel.
