Diseño e implementación de un sistema de riego automatizado, alimentado por un sistema fotovoltaico para el cultivo hidropónico en una planta piloto en el sector de San Vicente-Quero.

Abstract

This current work focuses on the design and installation of an automatized irrigation system with solar power for hydroponic farming of lettuce at Quero canton, aiming to guarantee the irrigation of de crop by means of a pump powered by photovoltaic energy, to do so, the radiation of the place and the water consumption based upon the technical data retrieved from NASA and hydroenvironment were determined. Based on the results, the required energy time for the functioning of the hydraulic system was determined a ¼ Hp pump, pipes and accessories from the photovoltaic system through a solar panel, controller, reversed and batteries; for the automatization a Hunter controller and electrovalves, allowing through the integration of the system, to guarantee 432 kWh of energy for the irrigation of 648 plants. Among the advantages achieved, a reliable automatized irrigation system is obtained , with low environmental impact, reducing water loss at 100% since it has direct contact with the root. At the time there is efficient use of the farming land because it uses a smaller space and a higher production is obtained compared to the traditional farming of the country. It is important to remark that the product obtained is organic and high quality, determined indeep for the direct absorption of the minerals included in the water for plant feeding as well as for not being in contact with soil.
