相較於太陽電池製造的蓬勃發展，台灣在太陽熱能與複合電熱系統(photovoltaic/ thermal, PVT)的發展就顯得緩慢許多，所以本研究針對電熱複合系統分析，透過暫態系統模擬程序TRNSYS軟體來模擬PVT系統。 本文中介紹太陽電熱複合系統，特別對太陽電池種類、熱收集器的結構設計、系統的種類與儲熱槽的型式做介紹，並透過TRNSYS軟體來分析PVT系統的性能。本文將中壢的氣象資料匯入TRNSYS軟體中，並透過參數的設定針對PVT-Air、PVT-Water與複合拋物面收集器(compound parabolic collector, CPC)系統做模擬，透過輸出的功率、溫度與效率來了解上述三種系統在中壢運轉的情形。TRNSYS軟體模擬中壢地區夏季(2008年7月~8月)與冬季(2008年12月~2009年1月)這三種系統的表現，PVT-Air系統效率最高可達27%、PVT-Water系統總系統效率最高可達39%而低聚光倍率的CPC系統模擬的效率最高可達61%，從模擬的三個系統來看中壢地區比較適合發展低聚光倍率的CPC系統。 Comparing with booming business of manufacturing solar cell in recent years, Taiwan research on solar thermal utilization and photovoltaic/thermal (PVT) application is far less. Therefore this study is aim to study the performance of PVT system, with the help of transient analysis using TRNSYS simulation software. This thesis first described PVT system and the structural design, various types of solar cell, thermal collector, and thermal storage. Then, the performances of PVT system were analyzed with TRNSYS. The weather data at Jhongli were imported into the TRNSYS and with adusting various parameters in the software to simulate PVT-AIR, PVT-WATER and CPC (compound parabolic collector) systems. With simulation of power output, temperature, and system efficiency, one can identify the performance of three systems that operate in Jhongli. TRNSYS software simulates two time sessions (July to August in 2008 and December in 2008 through January in 2009) for these three systems, and CPC has the highest efficiency (61%), PV-Water follow the second (39%) and PV-Air (27%) has the lowest value. Therefore, the CPC system is suitable to be implement in Jhongli area.
