Resumo
The benefits of solar energy are numerous, ranging from saving energy bills to reducing
environmental impacts since it is a renewable and clean energy source. Therefore, it is clear
that solar energy has both a social and an environmental impact. In this sense, the present work
aims to study the working principle of a small photovoltaic generating unit connected to the
electrical grid. First, a literature review was carried out regarding the main components of a
photovoltaic generating unit. A case study was carried out whose objective was to find a
solution for the inclusion of a photovoltaic frequency inverter to constitute a system that could
be installed in one of the buildings of the School of Electrical, Mechanical, and Computer
Engineering (EMC) of the Federal University of Goiás (UFG). Thus, the Laboratory of
Materials and Manufacturing Processes (LAMAF) was chosen. Eleven solar modules and one
inverter were selected to perform the simulation and a cost estimate for project implementation.
Next was a data comparison between the EMC meteorological station and the National Institute
of Meteorology (INMET). For this procedure, it was necessary to carry out a thorough data
treatment to verify if the studied location was suitable for implementing a photovoltaic system
and, also, to obtain the ambient temperatures provided by the EMC station. Then, the Radiasol
2 program was used to calculate the irradiance on the inclined plane, and the angle that captured
the greatest solar irradiance was also verified. After processing station data from EMC and
Radiasol 2, the average power supplied by both the photovoltaic generator and the inverter was
calculated. Finally, an estimate was made of the amount of energy generated by the photovoltaic
system for the year studied and the time needed to obtain the financial return that was initially
invested. It can be verified, through this study, the performance of the frequency inverter is
satisfactory and manages to meet the needs of the subsystem that served as an element for the
object of study.
