本文中介紹太陽光能充電系統的光能追蹤系統設計，由於太陽會隨著時間季節的不同而在天空的位置改變，所以為了提高太陽能吸收的效率，在本研究中提出一種低成本的追蹤太陽光照射角度的設計方案，並以動力機構驅動太陽能充電系統以面對光源所在，進而提升太陽光能的吸收，太陽光能追蹤系統包括幾個部分：連接太陽能光電板之介面、陣列式光阻感測器（CdS）、電腦控制單元、以及用於調整太陽能光電板接收角度與方向的機械驅動模組，本文的系統設計並包含偵測太陽能光電板上的光能量吸收特性，該追蹤系統的設計方案主要針對中國文化大學的所在位置而規劃，但亦可循相同模式修改為其他任何地點使用。
This paper describes the design of a low cost solar tracking photo-voltaic (PV) array system as part of an undergraduate senior project. The solar tracking system is interfaced with a solar panel, a mechanical driving mechanism, a signal amplifier and an analog to digital converter (ADC). Solar tracking is realized through ”field” programming using Lab View programming language on a lap-top computer and alternatively with a low cost solar radiation sensing transducer consisting of an array of photoresistors (CdS cells). Actuation of the panel tilt for azimuth tracking and rotation of the panel for solar tracking are operated with a gear motor-based control system for adjusting the PV mount system's position so as to collect maximum solar radiation. The gear motor controller module is built with state-of-the-art low-cost digital logic circuit with built-in flexibility to accommodate seasonal position adjustments of the PV mounts. The design includes a computer access for monitoring the power generation of the system. The system is configured for a solar radiation condition specific to the location of the system at the Chinese Culture University of the Shilin District in Yang Ming Shan, but could be easily configured for any other locations.
