A solar module 20 comprises first and second sheets 21 and 22 , a plurality of rows (a plurality of groups) of spherical solar cells 11 incorporated in between these sheets 21 and 22 in a state in which the conduction direction is perpendicular to the surface of the sheets, a mechanism for the parallel connection of each group of spherical solar cells 11 , a mechanism for the serial connection of each group of spherical solar cells 11 with the spherical solar cells 11 in adjacent groups, a positive electrode terminal 23 , and a negative electrode terminal 24 . A positive electrode is formed on the bottom and a negative electrode on top in the odd-numbered rows of spherical solar cells 11 from the left end, while a positive electrode is formed on top and a negative electrode on the bottom in the even-numbered rows of spherical solar cells 11. |
