Abstract
A solar cell array is constructed by connecting plural solar cell strings in parallel, and the solar cell array is arranged to have strings of two or more rated voltages. 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.
Claims28
A solar cell array in which a plurality of solar cell strings are connected in parallel, at least one of said solar cell strings having a first rated voltage and another of said solar cell strings having a second rated voltage, said first and second voltages being unequal, wherein a voltage-power characteristic curve of said solar cell array has one power peak.
A solar cell array comprising a plurality of solar cell strings having different rated voltages and being connected in parallel, each of said solar cell strings comprising a plurality of solar cells, said solar cells being connected in series and being the same kind.
A solar electric power generation apparatus comprising:
- a solar cell array comprising a plurality of solar cell strings each of said solar cell strings comprising solar cells having different rated voltages, being connected in parallel and being the same kind;
- and
- a power control device connected to said solar cell array.
