摘要

在太陽能電池及其模組的輸出量測方面，根據最大功率傳輸定理，一電壓源若要傳輸最大功率至負載端，則負載之電阻值必須與電壓源之內阻相等，符合阻抗匹配之條件來傳遞最大功率，若把太陽能電池，視為一穩定輸出的電壓源，其輸出量測輸出量測是一種可變負載方式的，來調整到達最佳工作點。
根據太陽能電池的特性，模擬設計一組量測儀器以電容器為負載，來達成太陽能電池在不同的環境的最大功率點與其他電氣特性的量測，以MATLAB進行模擬， 以驗證控制器之可行性與可靠度。

Over the last decades the energy crisis has increasing become the center of attention at the international level. Studies indicated that the solar energy, a free, low pollution type of energy source, could be the next key to solve the energy crisis.
Recently the solar power industries have rapidly grown. The needs for solar power panel brought up the new development and design of the electro-optical related components; hence the importance and accuracy of solar power panel testing and measurement.
This studied tracking and measuring system is based on direct measurement of using various capacitors setting to collect parameters such as the most efficiency point on the solar power panel, the working voltage point, and the working current point.
In order to validate the accuracy and reliability of such hypothesis, MATLAB was used to simulation the hardware circuitry.
