Abstract
El objetivo principal de esta investigación consistió en realizar una evaluación de las condiciones de radiación y posterior generación fotovoltaica para la macrozona centro sur de Chile, específicamente en la región Ñuble, en la ciudad de Chillán, para de esta manera identificar la radiación solar incidente para la implementación de un arreglo solar fotovoltaico sobre las paredes laterales y superior de una cámara de refrigeración móvil para actividades de postcosecha.
El análisis fotovoltaico se realizó mediante la comparación de los datos obtenidos en terreno con la implementación de un panel solar Jinko, en condiciones de máxima radiación en la estación del año de estudio. Para la medición de variables atmosféricas como temperatura y radiación solar en el plano del panel se utilizó un trazador de curvas E1000.
Los resultados obtenidos revelaron que es posible llevar a cabo una estimación de esta situación mediante la implementación de las ecuaciones del explorador solar, la que además contempla los efectos de la nubosidad en su modelamiento matemático.
Finalmente, la obtención de la energía generada reveló que para el mes crítico (el mes de menor irradiancia), para un día soleado, la generación fotovoltaica satisface los requerimientos energéticos para la cámara de refrigeración.
The main objective of this research was to carry out an evaluation of the radiation conditions and subsequent photovoltaic generation for the central- southern macrozone of Chile, specifically in the Ñuble region, in the city of Chillán, to identify the incident solar radiation for the implementation of a solar photovoltaic array on the side and top walls of a mobile refrigeration chamber for post-harvest activities. The photovoltaic analysis was carried out by comparing the data obtained in the field with the implementation of a Jinko solar panel, under conditions of maximum radiation in the season of the study year. To measure atmospheric variables such as temperature and solar radiation in the plane of the panel, an E1000 curve tracer was used. The results obtained revealed that it is possible to estimate this situation by implementing the solar explorer equations, which also considers the effects of cloudiness in its mathematical modeling. Finally, obtaining the generated energy revealed that for the critical month (the month of lowest irradiance), for a sunny day, the photovoltaic generation satisfies the energy requirements for the refrigeration chamber.
