Title:
LIGHT-COLLECTING SOLAR CELL
Document Type and Number:
Japanese Patent JP3478113
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate a work measuring the installation position of an electric power generating unit.
SOLUTION: Each electric power generating units 1 receives a light collecting lens, a solar cell, an electric power generation sensor, and a drive motor for moving the solar cell and the electric power generation sensor with respect to the light collecting lens. A computer 21 calculates a directional angle θ and an incident angle d of the sun light to the electric power generating unit 1 on the basis of a focal position, where the amount of electric power generated by the electric power generation sensor becomes the maximum, and calculates the installation directional angle θ and the installation inclined angle β of the electric power generating unit 1 on the basis of the directional angle θ and the incident angle d.
