ABSTRACT:
The heliostat field comprises the most expensive subsystem of a solar central receiver power plant. Cost reductions might be achieved by either total heliostat redesign or component substitution in existing designs. This paper discusses the value of changing any of several design

specifications in the current baseline glass/metal hel1ostat. Results are quantified in terms of the breakeven cost; i.e. the cost of a new design which will yield the same total system energy cost as the baseline system. Changes in mirror reflectivity. pointing accuracy. surface quality, canting and focusing strategy. heliostat size, and stow requirement are evaluated. Show Less
