Resumo:
The evaluation of a region’s photovoltaic potential is extremely important for estimating
the amount of electrical energy that can be produced at the site of interest. Given the need for
disseminating the use of solar photovoltaic energy, this work promotes the analysis of factors
that influence energy production, and further, performs an estimation of the energy production
potential of the Electrical Engineering Department of the Federal University of Campina Grande
(DEE-UFCG), where the studies were developed. These estimations are made through
mathematical equations that model the incidence of solar radiation on the Earth's surface, which
is based on the day of the year, the hour of the day, the latitude, and the position of the collecting
surface. Each variable used in the model will be defined, and, through visualizations and
discussions, the resulting effect caused by the most prominent of them will be highlighted. For
the inspection of the photovoltaic generation potential of DEE-UFCG, three case studies were
utilized: the first one has fixed collectors that are positioned to favor the production during the
winter months; the second one also has fixed collectors, but favors summer production; and the
third one, which adopts a system where collectors have their position adjusted twice a year, and
favors both winter and summer. Additionally, real sets of irradiation data are presented, aiming
to promote knowledge concerning the real characteristics of solar radiation incidence.
