Study goals
Analyze the economic viability of implementing a solar photovoltaic plant in a basic school unit located in the Mesoregion of West Potiguar, Rio Grande do Norte, Brazil.
Relevance / originality
The Brazil is a country with a high incidence of solar radiation, the use of photovoltaic panels in the public sector isn’t common. The study analyzes the economic viability of a solar power plant in sector in a less socioeconomically favored region.
Methodology / approach
The project's costs, expenses, and investment were projected, and mathematical indicators of economic viability were used, such as Net Present Value (NPV), Internal Rate of Return (IRR), Minimum Rate of Attractiveness (MIR), and the use of Simple and Discounted Payback.
Main results
The economic and financial study of the PV project pointed out elements that make the project viable. The small payback in relation to the useful life of the PV plant, about 5 years, high NPV and IRR of approximately 20%.
Theoretical / methodological contributions
The use and applicability of economic feasibility techniques in the public sectors of small cities in the Northeast Region is not common. Therefore, studies directed this theme become consistent in face of the information obtained from the economic/financial point of view.
Social / management contributions
The use of sustainable energy sources by the public sector in a region with high solar incidence and economically vulnerable. This is fundamental for economic in the public sector, with reduced spending and improving the allocation of public resources in other policies.
