本文旨在研製一雙軸式之太陽能追日系統，此乃由於傳統固定式的太陽能面板僅能固定仰角收集太陽光，若需考量調整太陽能面板使其與太陽入射光垂直，冀以獲取最大功率，則如何以追日系統方式達成最高效能之光電轉換效率，即躍為重要研究課題。本論文導入光感測元件作為偵測太陽光源位置的輔助設備，並將感知得到的差異訊號作為基準，據以驅動雙軸控制系統，因而可有效調整太陽能面板至期望位置。而為確認本文所提雙軸太陽能追日系統的設計可行性，本文並將所設計之系統加以硬體實現，同時予以完整量測與評估，實驗結果協助展現本文所提方法兼具綠能研發參考價值。

This thesis is aimed to develop a dual-axis photovoltaic tracking system. It is motivated because the traditional solar module can only absorb the sun light through the fixed position and angle, yet considering that solar panels need to be perpendicular to the incident light so as to obtain the maximum power, the way of reaching a higher photovoltaic conversion efficiency aided with the tracking system is emerged to be a crucial topic of study. This thesis starts with the employment of photo-sensing device as the auxiliary equipment to detect the
position of solar light source. Based on the detected difference signal, the dualaxis tracking system can be effectively steered to the expected place. In order to
confirm the feasibility of this dual-axis photovoltaic tracking system, the hardware design is realized along with the complete measurement and assessment. Test results help illustrate the research and development value of the method for green energy study.
