The Global Solar Radiation in the Southern Region of Ecuador

摘要

In this work an approach to the theoretical solar radiation in the South Region of Ecuador is presented, using the Hottel Model ([1] [2]), considering the cloudiness and the topography Shadows. The maps o f Global Solar Radiation are shown for the months of January, August and Annual one, considering the heights over the middle sea level extracted of the Digital Elevation Model. This work will allow specialists and engineers to know the most favorable areas for the location of photovoltaic or photothermic plants in the southern region of Ecuador. The effects have been analyzed by the orography and the methods used were discussed. The role of the orography is analyzed to improve the values’ product of the modeling of the solar radiation. Conclusions and recommendations are given.
