Abstract:
1. A solar tracking system, comprising: a first set of solar heat gain transducers that produce respective first electrical output signals to drive a reversible first motor for changing a vertical angle of a solar collector; a second set of solar heat gain transducers that produce respective second electrical output signals to drive a reversible second motor for changing a horizontal angle of the solar collector; each of the transducers having a thermistor in thermal contact with a thermal mass, wherein the thermal mass comprises a mass of conducting material to elevate in temperature while illuminated by the sun, and wherein the thermistor senses the temperature of the thermal mass and produces a corresponding one of the electrical output signals proportional to the temperature; and each of the transducers having the thermistor and the thermal mass contained in a solar energy collecting and heat insulating enclosure that is solar energy transparent.
