PURPOSE:To follow-up exactly the sun by an inexpensive constitution by providing plural/singular photodetectors of a solar light having directivity so as to cover almost the whole zenithal angle, and transmitting a signal of an angle whose photodetecting quantity is the largest. CONSTITUTION:A state that a condensing part 1 is at an elevation angle thetaalpha= 45 deg. is shown in the figure. The condensing part 1 is supported so as to be freely rotatable by a pivot 3 of a U-shaped horizontal rotary frame 2, and also constituted so that a condensing surface 5 is directed continuously toward the sun extending from the minimum elevation angle theta0=20 deg. to the naximum elevation angle 80 deg. centering around an axial core 4 for its rotation. The elevation angle of the condensing part 1 is driven by a reversible rotating motor provided on the inside of the rotary frame 2, and also the horizontal rotary frame 2 is supported so as to be freely rotatable by four rollers provided with a rotary shaft in a base 13, so that the horizontal surface can be rotated in the horizontal direction by the reversible rotating motor. |
