目前，对于远离电网的偏远农村地区和孤岛，最有前途的电力解决方案之一是独立的太阳能光伏（PV）可再生能源系统或太阳能-风能混合发电系统。本文介绍了香港一个岛屿上一个真实的远程太阳能光伏项目的调查结果。该独立光伏系统的额定功率为19.8千瓦，位于一个偏远的岛屿上，为当地居民发电。这个岛上的电力最初是由柴油发电机提供的，这种新的太阳能系统大大降低了燃料成本，减轻了环境污染。收集了2011年现场整个系统一整年的运行数据，从日能量平衡、归一化性能参数和整个系统能量利用率等方面分析了光伏阵列、逆变器、蓄电池组和整个光伏系统的能量性能。通过对系统的长期监测和评估，详细考察了系统的运行性能，为今后太阳能光伏发电在偏远岛屿的应用提供了参考。
Currently one of the most promising power solutions for remote rural areas and isolated islands which are far away from utility grid is the stand-alone solar photovoltaic (PV) renewable energy system or hybrid solar–wind power system. This paper presents the investigation results of a real remote solar PV project on an island in Hong Kong. The stand-alone PV system, rated at 19.8 kWp, is established on a remote island for power generation to local residents. Power on this island was originally supplied by diesel generators and this new solar energy system has significantly reduced fuel costs and alleviated environmental pollution. The on-site entire system’s operating data was collected for one whole year in 2011, and the energy performance of the PV array, inverters, battery bank and the entire PV system were analyzed in terms of daily energy balance, normalized performance parameters and overall system energy utilization ratio. The results from this long term system monitoring and its evaluation enables a detailed inspection of system operating performance with respect to the technical issues, which provides a useful reference for future applications of solar photovoltaics in remote islands.
