  鍾瑞永、李健、楊清富•2015•臺南區農業改良場太陽光電系統效率分析。臺南區農業改良場研究彙報66:68-76。

本文探討臺南區農業改良場總設置容量45.96kWp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10.71kWp,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12.69kWp及22.56kWp,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。

現有技術:近年來隨著太陽光電技術的發展,系統設置成本已大幅降低,目前太陽光電系統造價約6~10 萬/瓩(2)。加以政府促進綠能產業發展與推動相關專案計畫等措施,國內太陽光電應用普及率已逐年提高。

創新內容:本研究結合氣象站日照量數據推算系統理論發電量,並與實際發電量比較及估算系統發電效率。同時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。

對產業影響:藉由系統發電效率分析與適當的系統檢修及維護,將有助於提高系統發電效率、延長系統正常運轉期限與增加系統整體經濟效益。

Chung, J. Y., C. Lee, and C. F. Yang

Abstract

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 12.69kWp and 22.56kWp 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.

What is already known on this subject?
With installation cost down and government promotion, the application for solar photovoltaic system is becoming popular in Taiwan.

What are the new findings?
Radiation data collected from the climate station were used for analyzing and evaluating the efficiency of the amorphous silicon thin-film and silicon panel solar photovoltaic systems.

What is the expected impact on this field?
The efficiency of the solar photovoltaic system would be rising with performance rate checking and proper maintenances. It would also prolong the operating period and increase the profit of the solar photovoltaic system.
