Automatic Solar-Powered Irrigation System in Greenhouse

It is still very common to use electric power supply (ac) or diesel to power generators in agricultural operations. however, automated control systems in irrigation have made considerable progress in recent years and also renewable sources has been applied to various applications and also these sources have been used in agricultural field. this paper presents a prototype of an automated irrigation system used in a greenhouse (80 m^2) to produce its energy from photovoltaic solar panels. in the experiment, two solar panels (220w) has been mounted near the greenhouse and energy produced by solar panels stored in two gel type battery (200ah). this energy was used for water pumping. the centrifugal pump sucked water from deep well with 12 m. as a result, two main objective of this study was to determine (a) the amount of energy produced from solar panels, (b) the system performance on greenhouse irrigation.
