The Characterization of Deformable Photovoltaic Modules

Abstract

The system under investigation is a deformable photovoltaic–wind hybrid system which utilizes both solar and wind energy by combining PV modules with a vertical-axis wind turbine. This system contains 5 PV modules separated by 72° angles; these modules are attached to the blades of the vertical-axis wind turbine. This leads to each module receiving a different amount of solar irradiation, which affects the generated output power. In this study, the VOC and ISC of the modules were measured against different factors that influence the output power, including factors such as solar insulation, module temperature, module tilt angle θ, and module azimuth angle ϕ. These measurements were entered into the MATLAB curve fitter to produce a model of each parameter. The results showed that as the tilt angle θ decreased from the default, the VOC increased slightly, while ISC increased significantly. And when the module temperature increased, VOC decreased significantly, while the ISC increased slightly. The results of the study showed that by changing the module tilt angle and module azimuth angle, the solar insolation received at the module surface changed, which leads to different VOC and ISC values. Also, this study showed that the VOC and ISC values varied with time. © 2024 by the authors.
