太陽光電發電系統之模擬分析與性能評估

本研究首先將全台七個地點十套太陽光電發電系統之監測數據作統計，再使用Solar Pro模擬軟體分析其發電量及發電系統性能比，並將實際與模擬數據作比對分析找出其誤差值，以提高模擬之準確性，經由修改日照強度可使模擬軟體之年平均發電量準確率高達98%。再以工研院統計全台各地區之每日每kWp平均發電量為比較對象，探討及分析十套太陽光電發電系統每日每kWp平均發電量，針對系統發電效益較差之系統提出改善方案以提高系統效益。本研究分析台灣北、中、南三地區PV系統最佳之傾斜角及方位角，以獲取三個地區最佳之發電量，並找出北、中、南三地區系統設置傾斜角及方位角的差異性，由研究結果可看出最佳傾斜角均不會高於23.5°，方位角還是以面向正南180°為最佳。本研究之成果可供太陽光電發電系統，於架設前藉由模擬軟體預先評估系統之發電量、太陽能陣列因建築物遮蔭之影響及太陽能陣列傾斜角及方位角之最佳化設計、系統設計、規劃及性能評估之參考。

This thesis presents to statistical monitoring data for ten sets of seven locations photovoltaic generation system in Taiwan. Analyze performance ratio by using Solar Pro simulation software of actual and simulated data for comparative to find out the error in order to improve simulation accuracy of photovoltaic generation system. By modifying the irradiation of the software can simulate the average power output of up to 98% accuracy. Then all regions in Taiwan ITRI statistics daily average power output per kWp for comparison, discussion and analysis of ten sets of solar photovoltaic system generating capacity of the average daily per kWp. To improve the system proposed programs of the poor performance ratio to improve power generation. These thesis analysis northern, central and south areas of Taiwan for optimum tilt angle and azimuth to obtain the maximum generating power. And identify the northern, central, and southern regions and the azimuth angle system settings differences. Best results can be seen from the angle of inclination will not be higher than 23.5 °, azimuth 180 ° or in the main south-oriented. Results of this study could use to system design, planning and performance evaluation for photovoltaic generation system.
