Abstract

This paper presents a new model for the computation of the insolation in large territories. The main novelty of this work consists in that it reduces significatively the number of necessary arithmetic operations, and simplifies the calculations introducing errors that are inferior to the ones imposed by the climate in a territory. In particular, a faster algorithm to compute the horizon at all points of a terrain is provided. This algorithm is also useful for shading and visibility applications. Moreover, parallel computing is introduced into this model using grid computing technology to extend its application to very large territories.
