Abstract

Due to the geographic location of Brazil, due to its proximity to the Equator, it receives a high incidence of sun throughout the day, with little variation throughout the seasons, being the country that receives the most source in the world with more than 3,000 hours of sunshine, corresponding to a daily solar incidence that can range from 4,500 to 6,300 Wh/m², having a great potential for the use of this source for electric energy generation, through photovoltaic systems, although its use is little used with only 0.05% of use. This work aimed to simulate the potential of photovoltaic energy in Rio Grande do Norte, in the microregion of the Açu Valley. Using the SunData program, with the latitudes and longitudes, of the searched region, the means of solar irradiation were found. Mathematical calculations were used to determine the correlation between horizontal and inclined radiation components, as well as data on the region's infrastructure, to determine if this micro-region has the conditions for the implantation of a solar photovoltaic power plant.
