Abstract
In some rural areas of the country where there is limited access to the electricity grid, meeting the demand for energy generated by agricultural production is a challenge for farmers who must evaluate different alternatives to supply this demand. A particular case is the energy demand of greenhouse systems, commonly used to grow different types of plants that are highly susceptible to pests and changes in environmental conditions. Unlike greenhouses that use passive cooling systems, conventional greenhouses require air conditioning systems that consume electrical power in large amounts and irregularly throughout the day.
In this document, the design of a ventilation system for a greenhouse is presented and the technical-economic viability between a solar-photovoltaic generation system and a conventional electrical energy source is evaluated, as 2 power alternatives to provide electrical power. required by the greenhouse, specifically considering the particular case of a greenhouse located in La Brasilia farm, in El Cerrito - Valle del Cauca, which is specifically dedicated to tomato cultivation and due to the lack of an air conditioning system, it has been presenting problems and losses in production due to frequent increases in temperature. The scope of this project reaches the design and dimensioning phase, complementing it with an analysis of advantages and disadvantages, through the NPV methodology to determine the best of the 2 alternatives considered.
