A solar cell array is constructed by connecting plural solar cell strings in parallel, and the solar cell array is arranged to have two or more rated voltages of the solar cell strings. This arrangement permits the solar cell array to be designed so as to maximize the output capacity in an area where the solar cells can be installed. In addition, the arrangement has high degrees of freedom of design to enable to construct a preferred configuration in terms of the design. Further, the solar cell array can be provided in a device configuration of low cost. Also provided is an array constructing method to facilitate installation and wiring. <IMAGE> |
