Projeto de eficientização energética e sua viabilidade econômica para a central de laboratórios I no UFCG/CDSA.

Abstract

Renewable energies are being widely used in recent times already that consent to a more sustainable development, pollute less and avoid the use of exhaustible fossil energy. Solar energy has been gaining quite prominently in the days of today, there are more incentives in relation to costs, more practicality in its installation and acquisition of equipments that compose the installation project. With this, the objective of this study is to perform a sizing a solar system interconnected network (On-Grid) to a Central Laboratory of the CDSA/UFCG as form of efficiency and reduce monthly costs on the invoice of electrical energy. For the construction of the project, it was done the lifting of loads of equipment, calculation of daily and monthly consumption to establish the choice of photovoltaic inverters and generator. It was applied the methodology used at the Federal University of Lavras to calculate the total number of inverters and the quantity of panels. For the value of the total investment in the project was conducted a survey of prices over the internet, and to make an analysis of return we used a simple methodology applied, called simple payback, which uses the time needed to recover the value of the investment. Thinking about improving the efficiency and, consequently, reduce costs in the final value of the investment was carried out a new calculation with the proposal to make the replacement of 40 W fluorescent lamps by LED lamps, and it was found that the consumption was reduced by hal
