Apparatus For Automatically Directing Solar Radiation Focused By A Reflector

Abstract:
For the tracking control of a reflector focusing the solar radiation on an absorber corresponding to the apparent movement of the sun, an adjusting mechanism of the reflector is driven by means of a direct-current motor 5. The terminals of the electric motor are connected to a parallel connection consisting of two solar cells (9, 10). The parallel connection of both solar cells is such that they generate by constant radiation about a similar amount of voltage however with opposite polarity. The driving of the direct current motor takes place with the voltage differential occurring on the parallel connection. Both the solar cells are rigidly mounted to that part of the stationary arranged absorber on which part the solarrays are focused by the reflector. Both the solar cells are arranged symmetrical to the longitudinal axis of the absorber. With the help of the above described apparatus the reflector is automatically always so adjusted that the solarrays are focused on the absorber whereby no additional source of energy is necessary to drive the adjusting mechanism of the reflector.
