摘要

This paper reports a case study that involved studying and simulating the potential for photovoltaic (PV) electricity generation at Hojing Elementary School by using the RETScreen model. The electricity generation simulated by the existing 3.67-kW PV power system for 2011 was 5,428 kWh, which was very similar to the actual electricity generation for that same year (5,427.7 kWh). However, inaccuracies in the simulations over 8 months were greater than 10%. Based on the total rooftop area available for installing PV panels, a capacity of 355.12 kW and a total electricity yield of 174% of the school’s electricity demand can be achieved. The validation of the RETScreen model in this study indicated that the model is able to accurately simulate the yearly technical potential of proposed PV projects. However, the reliability of the model to analyze the potential monthly electricity generation of the proposed project needs to be enhanced.

本研究探討利用RETScreen模型模擬後勁國小太陽光電潛力。模擬現有3.67千瓦太陽光電系統2011年發電量為5,428度，與實際發電量5,427.7度極為接近，但有8個月模擬值的不準確度高於10%。依據校舍屋頂可安裝光電板的屋頂面積計算，共可安裝355.12千瓦的太陽光電板，可供應學校總用電量的174%。本研究的驗證顯示RETScreen模型可以準確模擬太陽光電每年的技術潛力，但分析每月發電量的可靠度仍有待提升。
