Title:
MODULE AND SYSTEM OF PHOTOVOLTAIC POWER GENERATION
Document Type and Number:
Japanese Patent JP3232058
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To prevent lowering of supply efficiency of light even if a transparent substrate is installed in a surface, by specifying the thickness of a cover glass part to a distance from a lowermost end of a reflection surface of a solar condenser to a light receiving surface when the light receiving surface is arranged above.
SOLUTION: Each of solar condensers 7-1, 7-2, 7-3 wherein a reflection surface 2 has a specified inclination angle to a module light receiving surface 1 is arranged so that an angle formed of the light receiving surface 1, and the reflection surface 2 faces the same direction. When a distance from a surface 36 connecting an upper end of the reflection surface 2 of each of solar condensers 7-1, 7-2 to the light receiving surface 1, that is, the thickness of a cover glass part 4 is Lg and a distance from a lowermost end of the reflection surface 2 of each of the solar condensers 7-1, 7-2, 7-3 to the surface 1, that is, a module thickness is Lm, a solar battery module of an asymmetry structure is effective if the cover glass thickness Lg is 30% or more, desirably 14% or more of the module thickness Lm.
