VIABILITY ANALYSIS OF A GRID-CONNECTED PHOTOVOLTAIC SYSTEM IN IFRN, CAMPUS JOÃO CÂMARA

Given the vulnerability of oil prices and the increase in CO2 emissions that impact on the climate and the planet's ecosystems, the use of environmental technologies, such as solar photovoltaic energy, it becomes essential to develop more sustainable economies. This article is a case study of integration of a grid-connected photovoltaic system (GCPVS) at the Federal Institute of science and technology of the State of Rio Grande do Norte (IFRN), campus João Câmara/RN, which aims to use clean and renewable energy such as solar for power generation, contributing to implement environmental sustainability practices and use technology for the benefit of society. As a result, the estimated payback of the return on investment is 11 years and at the end of 20 years, which is the GCPVS useful life, will have a positive net present value (NPV) of R$ 211,670.00, i.e. the system will compensate the amount invested and still provide a rate of return higher than savings rate.
