Abstract: An apparatus for supporting and aiming various solar devices. Includes a cradle assembly (70) with two tilt pivots (59) located on opposite sides for vertical adjustment, and a turntable (46) for horizontal adjustment. Both adjustments, required for aiming the device toward the sun, are accomplished simultaneously and instantly by steering a biaxial control arm (74) while sighting an aiming instrument (88). The instrument can be used for aiming the solar device either in a direct line or by using the novel aim-ahead indicia (101). An optional utility cart (140) is used for mobility. The cradle assembly locks in either a direct-fit solar device (226) or an adaptor box (110) that, in turn, latches to a standardizing interchange mount (122). The mount, along with a device mounting kit (FIG. 16D), converts various solar devices (FIGS. 2, 12B, 13, and 16E) from different manufacturers, to be utilized by the apparatus. A second embodiment (FIGS.
