常规光伏系统设计多以获取最大电能为目标，而对于非均衡负载独立光伏系统，为满足各时间段负载正常供电不得不提高整体光伏发电系统的容量，而导致大量能量浪费。本文剖析了独立光伏发电系统内部各模块间的匹配关系，特别考虑非均衡负载对系统参数设计的影响，在此基础上构思独立光伏系统参数设计新方法，以提高光伏系统的可靠性和经济性的匹配。新算法能同时适应均衡负载和非均衡负载系统的参数设计。本文最后，利用该算法，对广州某一非均衡负载的独立光伏发电系统进行了参数设计，并做了分析和对比。

Compared to stand-alone photovoltaic system, the traditional PV system wastes a large amount of energy due to the over-sized design capacity of the photovoltaic system for maintaining normal loads at all time. The paper discussed firstly the matching relationship amount different components of a stand-alone photovoltaic system, particularly the fluctuant load impacts on system parameters calculating. Then a new method for calculating the parameters for stand-alone photovoltaic system is proposed that can improve the system performance on considering both the feasibility and economy. This method can be also applied to systems with both balanced load and fluctuant load. Finally, the parameters of a stand-alone photovoltaic system in Guangzhou are calculated by using this method and validated against the experimental data.
