Investigation of photovoltaic panels using simulation tool during light intensity and temperature changes

Abstract

The precise procedure of the commercially available photovoltaic (PV) panels modelling with the use of simulation tool has been presented in this article. Photovoltaic module model (physical model) is available in the tool structure which allows input of the real module physical parameters. PV panels modelling methods including mathematical models and tools used in the discussed program have been presented in this paper. Current — voltage and power — voltage relation for the varying solar irradiation and temperature, were obtained through simulation, and further evaluated and compared with laboratory test results. The article covers restrictions of the PV module simulation possibility in the simulation software.
