Análise e cálculo do potencial de geração solar fotovoltaica das áreas em desertificação no estado do Ceará

Abstract

The generation of electricity from solar energy has been growing since 2012 and its participation in the Brazilian electricity matrix has increased exponentially. In addition, distributed generation has become an excellent alternative to promote the reduction of expenses with electricity. To maximize the gains with this modality, one should use places that aren’t used for economic activities attached, such as rooftops and non-agricultural areas. In this context, Ceará presents more than 16.6 thousand km² of desertification areas in its territory that have become a potential loss of financial and social resources for the state. Bearing in mind the points presented, this work presents an analysis of the potential of the areas in desertification in Ceará for the use of solar energy in the production of electric energy and proposes the use of this electric energy to reduce the consumption of the consumer units of Group B of the Government of the State of Ceará. For the study, the python programming language and georeferenced data were used to calculate the electric energy generation potential of the desertification areas. It was found na electric energy production potential of 230 TWh/year. Considering the consumption of the low voltage consumer units of the Government of the State of Ceará the proposed project presented a payback time of less than 4 years, totaling a savings of 1.6 billion reais in 30 years after the installation of the project.
