High concentrating photovoltaic system is the most potential for the current solar power systems. Using large-scale concentrator module can focus sun light on solar cells to reduce the solar cells size and the cost of power generation. Due to high efficiency solar cells and a wide range of the focus, the power generation can be increased, but is sensitive to the solar incident angle deviation and will be greatly attenuated when the deviation incident angle exceeds tolerance range. Therefore, to reduce the angle deviation and increase incident solar power generation, a solar path tracking method is applied in this study. An adaptive controller is applied to control dual-axis tracker, and a light position sensitive device is used to measure the light deviation angle and to verify that the sun tracking can significantly reduce the tracking error. 高聚光型太陽能系統為目前最具潛力的太陽能發電系統，利用聚光模組將大範圍的太陽光聚焦，並照射在太陽能電池上，如此可縮小太陽能電池面積，降低發電成本，且其因採用高效率的太陽能電池及大範圍聚焦，可提高發電量，但相對的，也因聚焦模式使對太陽入射光偏差角敏感，當入射光偏差超過容忍範圍，發電量將大幅衰減。 因此為了縮小入射光偏差並提高發電量，本研究採用太陽軌跡追蹤法，利用適應性控制器控制雙軸追蹤器，並以位置敏感裝置紀錄入奢光偏差，驗證採用適應性控制器及太陽軌跡追蹤法確實可有效縮小入射光偏差。
