  • In this work, we numerically evaluate with Monte Carlo ray-tracing simulations the intrinsic drift in heliostats. This drift is associated to the fact that the central ray does not necessarily coincide with the center of gravity of the flux map. For this investigation, the solar tower facility located at IMDEA Energy in Móstoles, Madrid (Spain) is used as a test case. By simulating flux maps at different times of the day and representing their centers of gravity the intrinsic drift is evaluated. The influence on the drift of the focal length of the heliostats and the projection angle of the flux distribution on the target is investigated in detail. Results show the relevance of the intrinsic drift in heliostats with short focal lengths and how this drift can be reduced by making the focal length of the heliostat closer to its slant range.
