独立光伏系统的需求计算研究
首发时间:2009-07-31
摘要:本文系统地阐述了独立光伏系统中太阳能电池,蓄电池需求的计算、选择原则以及安装注意事项。首先作者列出了计算所需要的数据,接着列出了到达太阳能电池板上,能被直接利用的太阳能即斜面上的总辐射日总量月平均值的计算公式,并提出了在实际应用中的工程简化计算公式,对最佳安装倾角的计算做了说明,应用中直接查表即可,无需计算。然后详细介绍了独立光伏系统中负载需求,蓄电池容量以及太阳能电池板容量的计算公式,并对在实际使用中具体的各项参数的处理进行了详细说明,提出蓄电池和太阳能电池的串并联计算以及选用原则。最后说明了一下安装注意事项。

The Demands calculation Research of Stand-alone PV systems
Abstract:This paper presents the demands calculation of solar cells and storage battery in stand-alone photovoltaic system ,and also describes the selection principle and installation precautions about stand-alone PV system. In this article, at first we list out data for calculation, and then introduce calculation formula about the monthly mean of daily total solar radiation which can reaches solar panel and can be used directly. Engineering Simplification formula has been proposed which can be used in practical application .The optimum tilted angle can be looked up in table without calculated. Afterwards we introduce load demand and battery capacity in stand-alone PV system. The calculation formula of solar panel capacity is listed and the parameters in it has been explained in detail. Series -Parallel of solar cells and storage battery and selection principle have been discussed. Finally, we discuss the installation precautions.
Keywords: Stand-alone PV Calculation of solar energy demand Solar radiation Optimum tilted angle
