Abstract

Iowa City is in the humid continental climate zone and the goal of this paper is to provide a thorough system performance analysis for PV systems installed in this climate zone. In this work we present the performance analysis of two photovoltaic (PV) systems installed at The University of Iowa in mid-2011. We analyze the system performance from mid-2011 to 2014. First system is a 39 kW-DC building-integrated amorphous silicon (a-Si) PV array. Second system is a 48.1 kW-DC solar charging station based on multicrystalline modules. We use National Renewable Energy Laboratory's System Advisor Model for the PV system performance analysis of the two systems and results of simulation are compared to measured energy yield. In addition, we compare PV system performance with the Iowa Energy Center Solar Calculator (IEC-SC) model for the mc-Si PV system. Our analysis indicates that the SAM model, with correct modeling parameters results in ±20% error relative to measured data whereas the IEC-SC model almost always over estimates the energy yield.

2011 - 2014年爱荷华州晶体硅和非晶硅光伏系统性能分析

爱荷华市位于湿润大陆性气候区，本文的目标是为在该气候区安装的光伏系统提供全面的系统性能分析。在这项工作中，我们展示了2011年年中安装在爱荷华大学的两个光伏(PV)系统的性能分析。我们分析了从2011年中期到2014年的系统性能。第一个系统是39千瓦直流建筑集成非晶硅(a- si)光伏阵列。第二个系统是基于多晶硅模块的48.1 kw直流太阳能充电站。我们使用国家可再生能源实验室的系统顾问模型对两个系统的光伏系统性能进行了分析，并将模拟结果与实测发电量进行了比较。此外，我们比较了光伏系统的性能与爱荷华能源中心太阳能计算器(IEC-SC)模型的mc-Si光伏系统。我们的分析表明，在正确的建模参数下，SAM模型相对于测量数据的误差为±20%，而IEC-SC模型几乎总是高估了发电量。
