Description
Summary:This article proposes an investigation into the impact of various constructive technologies for photovoltaic (PV) modules released on the global market since 2014 on the accuracy of existing nonlinear global models that are based on National Renewable Energy Laboratory (NREL) PV module database, published in 2014. The goal of this study is to determine whether a new database is necessary to consider these technologies. The article outlines the methodology used, which involves comparing selected parameters from 180 module datasheets from 21 manufacturers to those obtained from the publicly available NREL database. The evaluated construction technologies include Passivated Emitter Rear Cell (PERC), Multi-Busbars (MBB), Graphene Coating, Half-cell, and Bifacial Cells. The digest provides that the differences in the electrical characteristics are no greater than 3%, showing that the existing models, based on NREL's database, are likely to form good mathematical models for the new building technologies.
