After layout, it would be useful to report the total field annual efficiency (estimated) and the annual efficiency of each heliostat. This can be estimated from the sample of layout sun positions that are simulated. It would also be nice to do a DNI-weighted efficiency (essentially annual production) to give a better picture of which heliostats are actually contributing the most or least throughout the year.
