Verification of Photovoltaic System Modeling Codes Based on System Experiment Data

摘要

The ability to predict system performance is important to the design, evaluation, and economic justification of a photovoltaic (PV) system. Of the many performance models available, little effort has been devoted to assessing their accuracy. This paper describes verification effort to quantify the accuracy of the PV F-Chart and SOLCEL-II performance models based on field data. The SOLCEL-II and PV F-Chart models were selected because of their availability, past use, and documentation. The PV F-Chart model is a simple microcomputer designed to predict long-term performance for planned PV systems. The SOLCEL-II model is a more complex model, requires hourly input data, and is most applicable for use by engineers in evaluating an existing PV system. This effort confirms that both models meet their design objectives accurately. (ERA citation 09:025705)
