Integration of a Pilot PV Parking Lot and an Electric Vehicle in a University Campus Located in Curitiba: a Study Case

Abstract

Considering the increasing adoption of Hybrid Plug-in and Electric Cars, there are concerns about recharging process of these vehicles considering the capacity of grid to provide sufficient energy to that purpose. In the past years, the growth of distributed energy generation from renewable and clean energy sources, especially photovoltaics, represents a possible and feasible solution to supply the energy used on recharging electric vehicles and reduction of greenhouse emission gases as CO2. This article is a study case that analyzes the energy production of a solar carport, located at Federal Technological University of Paraná (UTFPR) at Neoville Campus, comparing with energy consumption of a commercial electric car for a city use purpose. Based on solar energy generation, data from the web monitoring platform, real positioning characteristics of the solar carport installation, irradiation data collected from the National Institute of Meteorology basis and with a solarimetric station located at the same place as the solar carport is installed, the solar energy production is rated using three different metrics: yield, performance ratio and capacity factor. These metrics are calculated with RADIASOL2 software, a free and precise tool, developed by Federal University of Rio Grande do Sul (UFRGS) to execute computational simulation of photovoltaic systems using mathematical models. The results showed a slightly low energy production performance than expected, but more than enough energy to recharge an electric vehicle for a day use, demonstrating that a solar carport system could be a good solution to meet the energy demand for this application.
