PROBLEM TO BE SOLVED: To improve filling rate on the installation surface so as to increase quantity of generated energy, by arranging a plurality of square solar battery modules in coexisting state of which width is small and which are similar in width to each other and different in length from each other. SOLUTION: Solar battery cells 103 and 104 for solar battery can be made of single crystal, polysilicon, micro crystal, or amorphous, and not limited to such materials. The modules 103 and 104 are desirable to have almost the same current characteristic. To allow the modules with different lengths to have almost the same current characteristic, basic cells constituting the modules are preferably formed of ones having almost the same area and current characteristic and formed in series and parallel. Because, when the current characteristics of the respective cells are different from each other, the series, parallel connection to realize a desired current characteristic becomes complicated. |
