我們提出了兩種由數個偏折元件所組成的靜態集光器系統，它們可將傾斜照射的陽光往垂直方向做轉變。其中，偏折元件的外觀為二維長柱形，並且沿著台北的東西方向排列，使它在二維視點上都能接受太陽光全天候的照射，並且縮小其出光角度，達到準直的效果。我們根據向台北中央氣象局索取來的氣象資料來定義我們系統所要準直的角度範圍。接著我們針對不同結構的偏折元件進行設計與探討，並比較個別的性能。為了要評估系統的性能，我們也定義了一個參數用以計算並表達系統的偏折能力。最後，我們分別將兩種靜態集光器系統與本實驗室所開發的太陽能集光板結合，用以改善太陽能集光板的集光效率。

We present two kinds of static concentrator system made up of several refractional units for changing slanted sunlight to vertical light. The refractional units are two-dimensional cylinder and were placed to face the sun over Taipei. They can receive sunlight all day and reduce the angle of exit light. We used meteorological data from the Central Weather Bureau in Taipei to define the collecting range of our systems. Then we design and discuss the structure of refractional units and compare their performances. For evaluating the performances, we define a parameter to evaluate the refracting capability. Finally, we combine the static concentrator with a collection element design by our Lab to improve the response of the collection element.
