OPTICAL POSITION SENSOR, OPTICAL TRACKING SYSTEM AND OPTICAL TRACKING TYPE POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an optical position sensor, an optical tracking system and an optical tracking type power generation system utilizing a solar battery that can obtain positional information, such as height and direction of a light source through adequate allocation depending on the regional environment to generate electrical power with the solar battery, place and a kind of light source. SOLUTION: There is provided an optical position sensor 10, an optical tracking system and an optical tracking type power generation system for detecting positional information of a light source from difference in an amount of power generation of each solar battery cell 1, by laying a plurality of solar battery cells 1 to the significant layout positions.
