Abstract :
Five algorithms for sun position computation, with validity from 2010 to 2110, are proposed and discussed. The algorithms have different
accuracy levels, with maximum errors in the solar position spanning from 0.19 to 0.0027 , thus covering a wide range of possible
applications. The algorithms are optimized in order to reduce their computational cost as much as possible. The extended time range of
validity allows users to employ these algorithms even in long-term projects.
