Energy efficiency analysis of an Isolated Photovoltaic System (SFA) for a charging station

Abstract

Renewable energy comes from inexhaustible natural sources, so its use will reduce the excessive operation of non-renewable sources. In Ecuador, the use of non-conventional renewable energies is promoted by law. The objective of this work is to analyze the efficiency and feasibility of a fixed Isolated Photovoltaic System (SFA) with a mobile SFA. This was achieved with the use of: solar panels, batteries, MPPT charge controllers, metal structures, cables, Arduino Uno module, transformer and an MG996R servomotor to control the panel. PVGIS was also used to simulate each system. As a result, a mobile SFA was obtained, which, at an energy level, is more efficient than a fixed SFA, with 13 % more production. However, the implementation cost is not offset by the production obtained. On the other hand, comparing a fixed SFA with double power with a mobile SFA and a fixed SFA, at an energy level it is superior, however, more space is needed for implementation as it has two panels. In conclusion, a fixed SFA with double power is superior to all the previously proposed systems, since the implementation cost is compensated by the amount of energy produced.
