Abstract:
A solar panel of the present invention, above which a pointer mounted on a pointer shaft inserted in a through hole in a center portion of the solar panel moves, includes a plurality of solar cells arranged in a substantially circular shape, and these solar cells have been divisionally formed into a substantially spiral shape so that the pointer is positioned over two of the plurality of solar cells. Accordingly, the pointer can always be positioned over two of the plurality of solar cells, and therefore a decrease of light-receiving area due to the pointer can be distributed between the two solar cells. As a result, a decrease in the output current of the plurality of solar cells over which the pointer is positioned can be suppressed, and the output current of the entire plurality of solar cells can be improved.
