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

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.
