Sistema de bombeamento fotovoltaico em propriedade rural – um estudo de caso.

Abstract

Pumping water for irrigation and animal watering is quite common. in rural properties, a practice that entails high costs with electricity. Therefore, it is important to insert technological means that reduce these costs and solar/photovoltaic energy can be pointed out as a viable alternative, because in addition to the low cost, it provides environmental benefits. This study had The objective is to dimension a pumping system using photovoltaic energy, to irrigation of forage crops and animal watering in the sertão of Paraíba. For that came true the characterization of the study area, aiming to obtain the water demand design and radiation data at the implantation site. for the sizing of the system, composed of thirteen photovoltaic panels, an inverter and eleven batteries, followed the following steps: verification of the discharge system, sizing of photovoltaic panels, selection of the inverter and sizing of batteries and cabling. Finally, it took place analysis of economic and financial viability of project and estimated the amount of carbon dioxide that can be avoided from releasing into the atmosphere with the adoption of the measure. The total project cost was estimated at R$ 31,182.02 and expected return on investment for the sixth year after implementation of the system, with a profit at the end of its useful life of almost R$ 350 thousand. The measure may avoid the emission of more than 50 thousand kg of CO2. concluded that the system of proposed photovoltaic pumping is a good alternative, in addition to providing economic and environmental benefits.
