Figure 7. Heliostat price as a function of annual production volume. These prices apply to a heliostat with a surface area of 150 m2 and similar in design to those tested at Sandia National Laboratories.

Since the heliostat field represents the largest single capital investment in a power tower plant, advancements i n technology are needed to improve the ability to manufacture, reduce costs, and increase the service life of heliostats . In particular, a lower cost azimuth drive system is needed (i.e., to rotate the heliostat around an axis that is perpendicular to the ground).
