SOLAR LIGHT COLLECTING DEVICE, CONTROLLING DEVICE FOR SAME, AND SOLAR LIGHT REFLECTOR CONTROL METHOD

摘要

The purpose of the present invention is to ascertain solar light reflective properties of a heliostat caused by dirt, scratches, or distortion of a mirror over time. The present invention pertains to measuring solar reflective properties of the heliostat by exposing a measuring mechanism to light reflected from one of a plurality of heliostats. By virtue of the present invention, the solar reflective properties of each of the plurality of heliostats can be ascertained.
