Heliostat assemblies, including fabrication methods, providing capability for azimuthal and elevational sun-tracking. A plurality of mirrors are affixed in a rectangular array which is diametrically mounted within a pair of circular rims which extend perpendicular to the mirror array. A belt-type drive rotates the rims on loadbearing rollers to adjust the elevational orientation of the mirror assembly, and a second drive rotates a carriage upon which the rollers are mounted to adjust the azimuthal orientation of the mirror assembly. Lightweight compression members and sectional shapes transfer loads among the assembly components, including tension cables which assist in transmitting loads between the elevation rims and the mirror assembly.
