Abstract
In this work, a geometrical model is used to evaluate the sun radiation reflected from the heliostats toward
the aim point on the tower top, by taking into account the shading and blocking between neighboring
heliostats. This results in an analytical expression for the heliostats efficiency, which can provide very useful
informations for the optimization of the heliostat field. In particular, we obtain a very simple and exact
expression of the maximal energy collectable by the solar field and present effective strategies to reach such
maximum.
