The growing environmental impact and rising emission of greenhouse gases have accelerated the research toward renewable energy sources and electric vehicles since one of the main sources of pollution is the CO2 emissions produced by conventional combustion vehicles. This article presents the analysis of the energy balance between a photovoltaic carport with 4.89 kWp installed capacity and an EV, model Renault Fluence ZE DYN, driven in real conditions. The driving tests were performed during the winter season in the city of Curitiba, the capital of the state of Paraná, Brazil, with approximately 1.7 million inhabitants and 1.1 million vehicles. During the test period, we attempt to reproduce the citizen’s daily routes through the city, presenting an average consumption of 15.75 kWh/100 km. The carport PV module’s energy generation and in-plane incident irradiation were acquired to calculate the performance ratio, making a comparison after cleaning maintenance possible. The solar carport system has 4.89 kWp and has generated an average of 465.37 kWh during its 24 months of operation. The analysis scenarios consist of replacing part of the city’s combustion vehicle fleet with the EVs (the same as used in the study) and thus determining how many replicas of the presented photovoltaic systems might be needed, as well as the area required for the installations. In a simulation with 15% of the fleet’s replacement, it would be necessary to generate 17,151.8 MWh, which requires the construction of 36,856 carports, covering an area of approximately 1,105,685 m². Finally, an economic comparison between an internal combustion vehicle and the EV determined that the expenditures involving electric energy to charge the batteries are 3.3 times lower than buying gasoline, assuming the same driving routines.
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, HIGHLIGHTS Increasing electric vehicles against utility grid energy supplying capacity. Solar Carport system as a solution to provide energy for EV recharging needs. Performance analysis of a real solar carport energy production. Comparison between energy production and electric vehicle consumption for a day use.
