摘要

隨著太陽能電池模組單位成本的降低及政府能源政策的推廣，太陽能電池將是未來主要的能源之一。降低模組溫度或提高模組日照強度可改善太陽能電池之電力輸出，欲降低模組溫度可將其與地面保持散熱空間，欲提高模組日照強度，則須將其安裝在最佳日照強度之位置，以獲取較大的電力輸出。本文以理論分析，計算出任何時間地點太陽運行的位置與軌跡，應用於模組日照強度的變化，模擬太陽能電池於任何傾斜角度或方位時之電力輸出，其結果可以提供大型固定式太陽能發電系統最佳安裝位置之參考，或屋頂與樓房外牆安裝太陽能電池時之電力評估。

With the cost going down and encouragement from national energy policies, photovoltaic cells have become one of the most important energy resources for the future. The output power increment of photovoltaic cells is mainly based on two factors. One is decreasing the cell modular temperature and the other is increasing the cells' received solar illumination intensity. The former can be simply achieved by maintaining a proper radiating space between the modules and the ground. The later is more complicated. One needs to consider the installation of cell modules and then the maximum power output which can be derived. This paper will theoretically calculate the solar orbit and position at any time and any location. With the estimation of our model on the variation of solar illumination intensity, we can derive the output power of the solar modular cell at any tilt angle and orientation. The simulated results could be utilized in large-scale photovoltaic power generation systems when considering placement for optimal installation. It also provides a useful evaluation for the output power of photovoltaic cells mounted on roofs and outwalls of buildings.
