Análise de um sistema solar para aquecimento de água residencial.

Abstract

With growing concern about energy saving, its conscious use and the use of renewable sources, it is necessary to know the current conditions of technical and economic feasibility for application projects that meet these needs. This work will consider the use of solar collectors water heating in the city of Campina Grande in Paraiba. For that matter, it´s possible to use methods of economic engineering as Net Present Value (NPV), Internal Rate of Return (IRR) and Payback to assess how advantageous this system is today.
