太陽能板放電是依據光電原理，將太陽能板所接收到的光能轉換成電能之後輸出到負載上，因此只要可以接收到太陽光源的地方就可以產生能量，所以太陽能是解決環境汙染及能源短缺的最佳選擇之一。由於太陽能板的光電轉換效率過低，所以如何在有限的轉換效率下獲得最大的放電功率是目前最為熱門的研究。
本文提出以LabVIEW圖控界面結合USB-4711資料擷取卡設計太陽板最大功率追蹤系統。藉由USB-4711擷取到太陽能板之電壓訊號傳回LabVIEW，判斷出最大電壓位置，並加以控制AC伺服馬達轉速及轉向，使太陽能板保持在最大光源之位置獲得最大功率。經由實驗證明，本文所設計之太陽能板最大功率監控系統，可以正確追蹤太陽能板最大電壓訊號輸出位置，驅動AC伺服馬達，使太陽能板在有效的光電轉換效率下，可以獲得最大的放電功率。

Solar panel is based on the photoelectric effect which convert light energy into electrical energy, so we can get the energy wherever the sun light. Solar energe is one of the best solution to environmental pollution and energy shortage. Because solar panel has low efficiency of the photoelectric conversion, so how to get the maximum power of the limited photoelectric conversion efficiency is currently the most popular research.
In this paper, we used LabVIEW and USB-4711 to design a solar panels maximum power tracking system, USB-4711 acquires solar panels voltage signal to LabVIEW, the SCADA system will detect the position of maximum voltage, then control the solar panel tracking the maximum power point by AC servo motor. The experiment results are provided to confirm the performance and effectiveness of the proposed solar panel maximum power tracking system.
