Abstract:

A solar powered, solar aiming device pivotally mounted on a base 40 uses a pair of separate solar sensor panels 11 and 12 that are insulated from each other and oriented at an angle to each other. Hydraulics angularly pivot the sensor panels relative to the base in response to pressure produced by sunlight shining on sensor tubes 13 and 14 arranged within the sensor panels to contain refrigerant material. The refrigerant communicates with and pressurizes a pair of bladder separators 21 and 22 that separate the refrigerant from hydraulic material operating the hydraulic pivoter. Sensor tubes 11 and 12, separators 21 and 22, and the hydraulics are arranged so that when an aiming plane 18 bisecting the angle between the sensor panels is aimed at an angle from the sun thus causing the sensor tubes to receive different incident sunlight and reach different temperatures, the refrigerant material applies different pressures to the respective separators which in turn power the hydraulic means to pivot the sensor panels and correct the solar aim of bisector plane 18. The device can be used to aim a solar energy collector or other solar device oriented perpendicular to the aiming plane between the sensor panels.
