<p><P>PROBLEM TO BE SOLVED: To obtain highly efficient power generation by controlling a photovolatic panel to continuously face directly the sun in photovolatic power generation. <P>SOLUTION: Holes of several centimeters in diameter are provided on a board on which a photovolatic panel is mounted. An optical sensor is disposed on each of four interior sides. Upon sensing light, the sensors moves the photovolatic panel in the direction in which shadows are not detected, thus causing the photovolatic panel to continuously face directly the sun. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
