AUTOMATIC SUN TRACKING TYPE SOLAR GENERATOR

摘要

PURPOSE:To improve generating efficiency by allowing a control device to drive a driving means and the direction of a photodetecting face is changed so that the quantity of photodetection to respective optical sensors is equalized when the incident angle of sunlight is changed and the quantity of photodetection to respective sensors in an automatic sun tracking sensor is equalized. CONSTITUTION:When the incident angle of sunlight is changed and the quantity of photodetection to respective optical sensors in the automatic sun tracking sensor 22 is equalized, the control device 34 drives the driving means to change the direction of the sensor 22 so that the quantity of photodetection to respective optical sensors is equalized. A solar battery 23 fitted to a photodetecting face on which the sensor 22 is fixed is controlled so that sunlight is radiated to the solar battery 23 always at a maximum incident angle (approximately vertically). Consequently, the solar battery 23 can be directed so that the quantity of generation is maximized and the generating efficiency can be improved.
