一般市售太陽能模組分為家用型與商用型,商用型主要設立大規模的集熱區域,利用太陽能發電賺取利潤;而家用型多半由數片太陽能板組合而成,提供家庭部分供電。
此次研究主要是為了提高單片太陽能板的發電效率,由於太陽能板的發電效率與太陽能電池的溫度相關,因此在此設計散熱系統使之降溫,其中散熱系統是由冷卻流道、熱交換器、儲水槽以及加壓幫浦組合而成,又分成熱交換器輔助散熱型、儲水槽輔助散射型以及整合散熱型三種散熱系統。
本論文利用先前文獻中的環境參數及設計參數做模擬分析,分析三種冷卻系統分別提升的效率值,並與無冷卻系統的太陽能模組及理想冷卻系統的太陽能模組做比較,得到熱交換器輔助散熱型、儲水槽輔助散射型以及整合散熱型的效率增益η_G分別為4.86、5.01及6.52%,而理想設計程度D_i分別為0.63、0.65及0.84。此次結果將有助於後續串聯式太陽能模組的冷卻研究,另外,將整個冷卻循環運作下的廢熱,回收並加以利用,這也正是「節能減碳」的一種表現。
