RESUMO:

Photovoltaic solar energy presents itself as one of the most promising renewable sources to diversify current energy matrices, as its advantages are significant, especially when compared to the most used sources on the planet. Its exponential growth has been taking place on a national and global scale. In this context, the general objective of this work was to analyze the process of expanding the use of photovoltaic solar energy in Mossoró/RN between the years 2015 to 2021. Secondly, we sought to identify the main advantages and disadvantages of using photovoltaic solar energy in Brazil and in the World. The methodological procedures were divided into three stages: in the first, a review of literature and documents was carried out to support and delimit the research; in the second stage, a systematic literature review was carried out to identify the advantages and disadvantages of using photovoltaic solar energy on a national and global scale. For this, a set of criteria was established for the selection of the literature to be analyzed; in the third stage of the research, a geospatial database was set up with information on the location of residential and commercial installations of solar panels in Mossoró and three other municipalities in the Northeast region of Brazil. Then, thematic maps were prepared for data analysis and interpretation. As a result, the systematic review pointed out a total of 26 advantages of using photovoltaic solar energy, with emphasis on the absence or low emission of Greenhouse Gases, possibility of use in remote areas, alternative locations and different economic activities and high cost benefit, considering the useful life. 16 disadvantages were also identified, such as high initial cost, need to increase appropriate regulations, for non-economic obstacles that can hamper the effectiveness of policies and support schemes and lack of business models for financing in the private sector. Regarding the geospatial analysis, the study identified that in Mossoró there is a concentration of installation of solar panels in neighborhoods with higher purchasing power, with a concentration in residential condominiums, closed horizontal middle and upper middle class. In comparison with other municipalities in the Northeast region, a similar and accelerated scenario of growth in the use of residential and commercial photovoltaic solar energy was noticed. The data analyzed in the research also suggest that, in Brazil in the last five years, there is a direct relationship between the growth in the use of solar energy and the increase in the value of the MWh of electricity and between the growth in the use of solar energy and the kWp reduction. Finally, it was found that the exponential growth in the use of solar energy in Mossoró follows the national and global scenario due to factors such as: the existence of several sources of financing, economic and environmental advantages and investments in research.
