Critérios para dimensionamento de sistemas de bombeamento de água utilizando energia fotovoltaica isolada da rede sem baterias

Abstract

Water is a natural and essential resource for human life, its scarcity, unfortunately, is present in places within the national territory, which causes several problems in the economic, social and health spheres of the inhabitants. On the other hand, the incidence of solar energy is present throughout the national territory, and with the advancement of energy generation through the sun, an alternative to assist in the water supply of small and medium rural units is by pumping water using energy photovoltaic solar. The methodology was conceived, in the manner that allows, in an uncomplicated way, the complete sizing of the pumping system, without the need to implement batteries, which until now, have a high initial cost and a short period of useful life, being replaced by elevated reservoirs of water, transporting it by means of gravitational energy. Still, in the methodology, it was decided to demonstrate practical examples of calculations and to present free tools that help in the sizing, allowing laymen in the subject to calculate and implement their own water pumping system.
