Estudo da viabilidade técnica e econômica da aplicação de energia elétrica fotovoltaica em uma edificação unifamiliar.

Abstract

The implementation of the residential photovoltaic generator system is a project considered relatively simple considering its execution, and quite effective in terms of low maintenance and high adaptability. Given these points, it can be considered a very promising project when it comes to sustainability. As the energy crisis is a global concern, it becomes increasingly essential to focus on non-traditional and decentralized energy sources. The present study aimed to evaluate the technical and economic feasibility of using photovoltaic energy with reference to a single-family dwelling, having as reference a house for 4 inhabitants with an estimated energy expenditure of 484.38 Khw. The amount of 460 Watt photovoltaic panels needed to compensate for this consumption was 8 units and through a project following all the safety and stability regulations of the system we were able to make a list of materials together with a budget, concluding that the system is viable both technically and financially, reaching a Payback of 9 years and 1 month and a NPV (Net Present Value) for a useful life of 25 years of 17,678.12 at 5% rate.
