Análise de viabilidade econômica para instalação de um sistema fotovoltaico em uma indústria metalmecânica em Guaporé – RS

Abstract

Brazil is a country privileged in terms of solar radiation and, due to the high levels of solar radiation in large extensions, is one of the countries with the most suitable conditions for the use of solar energy. This study evaluates the economic viability of installing a photovoltaic system in an industry, with the system interconnected to the local power distribution network. A survey of the energy demand of the industry was carried out, through its energy bills corresponding to the period of one year. Based on these data, the system was designed to meet the energy demand of the industry and the availability of area for system installation. After the analysis of economic feasibility, it was observed that for a return period of more than twelve years the investment becomes viable for the company. Considering that this type of system has a useful life of approximately 30 years, it can be affirmed that before the half of the life of the system, the investment will already be paid and bringing financial return to the company.
