摘要

本文探討臺南區農業改良場總設置容量45.96 kWp之不同類型太陽光電系統的發電效率，本系統分3區：溫室區屋頂設置非晶矽薄膜透光型系統10.71 kWp，設置高度約3.5公尺；DB、DF棟倉庫區屋頂分別設置一般型太陽光電系統12.69 kWp及22.56 kWp，設置高度約11.5公尺。本研究以101年至103年全年度發電量數據與同時期本場氣象站所量測的日照量數據，比較推算理論發電量與實際發電量比值，用以推估系統發電效率。並進行薄膜型與一般型太陽光電系統分區發電效率比較，評估兩型太陽光電系統發電效率差異。101年本系統設置初期全區發電效率達84.2％，102年及103年度分別為77.2％及78.7％。101年至103年期間系統整體平均發電效率79.9％，分區發電效率則為溫室區78.1％、DB區82.0％及DF區79.7％，在不考慮各區安裝面積、角度及設置高度差異下，本場薄膜型太陽光電系統發電效率略低於一般型太陽光電系統。

The efficiency of solar photovoltaic system at Tainan District Agricultural Research and Extension Station (DARES), Council of Agriculture was analyzed and evaluated in this study. A 10.71kWp amorphous silicon thin-film system with 20% transparency and two silicon panel systems with 12.69 kWp and 22.56 kWp capacities are included in the solar photovoltaic system. The radiation data between 2012 and 2014 collected from the climate station located at Tainan DARES were used for analyzing and evaluating the efficiency of the solar photovoltaic system. The performance rate of the solar photovoltaic system was 84.2% in 2012, 77.2% and 78.7% respectively in 2013 and 2014. The mean performance rate was 79.9% between 2012 and 2014 with 78.1% in the 10.71kWp amorphous silicon thin-film system, 82.0% and 79.7% respectively in the12.69kWp and 22.56kWp silicon panel systems. The efficiency of amorphous silicon thin-film system was a bit lower than silicon panel ones in the solar photovoltaic system at Tainan DARES, COA between 2012 and 2014.
