為了提升太陽能電池的發電效率，雙軸太陽追蹤系統的開發逐漸受到重視。在本文中，利用了太陽軌跡追蹤法進行太陽的追蹤，使用GPS所提供的緯度、經度、時間和方位角數據並且搭配微控制器Arduino 2560進行太陽軌跡方程式的運算以及完成追蹤程式的撰寫。搭配電子羅盤及重力感測來計算出追蹤機構的仰角以及方位角與太陽的軌跡(仰角與方位角)相符合進行驗證。另外利用光敏電阻感測器的電壓數值變化的觀測來判斷太陽追蹤成功，所有數據存取在電腦中並且利用軟體進行分析與判斷正確的方向性。

In order to enhance the efficacy of solar cells, the development of two-axial solar tracking system becomes more significant. In this study, the solar trajectory tracking method from GPS data is constructed. The solar trajectory was formulated with latitude, longitude, time and azimuth which are provided by GPS and the calculation from a microcontroller Arduino 2560, coding the program for the tracking system. The elevation and azimuth of mechanism was calculated using compass and gravity message to verify the trajectory of solar. To judge the successful solar tracking, a verification system is set up using photo-resistor light sensor arrays. All the experiment information is saved in the computer to analyze the information for the correct direction of tracking system.
