Veículo elétrico movido a energia fotovoltaica com sistema de rastreamento solar

Abstract

There is a growing awareness of the need to achieve a more sustainable mobility. In the past years efforts are being made to increase the application of photovoltaic solar energy in electric and hybrid cars. However, this possibility of application is questionable, since the efficiency of photovoltaic panels is low in comparison to other energy sources. In the present model of a photovoltaic electric vehicle solar tracking device was developed. The aim of this study was to compare the two alternative photovoltaic systems, one fixed, with the photovoltaic panel (PV) arranged flat, and one mobile equipped with a solar tracker. Experimentally it was investigated the energetic performance of the system based on the electric performance of the photovoltaic panel and the velocity of the vehicle, using statistical inference tests , comparisons with other works of the literature. The results showed with, 95% confidence, that using the solar tracker on sunny days can increase up to 16,3% of the energy produced by it. Already on cloudy days there was no advantage with the use of this device. In the model, the average speed obtained with the use of the tracker was 0.85 m/s about 30% higher than that obtained without using this device so, with 95% confidence, we can conclude that using this technology on electric vehicles can significantly improve their performance.
