To obtain a solar battery panel device which is in harmony with a roofing, exhibits the sense of unity with respect to the roofing, and is good in appearance.
In the determination of longitudinal and transverse sizes of a solar battery panel 1 set on an inclined roof, the transverse width Z of the solar battery panel 1 is set to a width A between the left edge of n pieces of right roofings 31 and the right edge of n pieces of left roofings 32 which are arranged in the roofing width B direction of the roofing 30, and based on a relation between a gauge D of the roofing 30 in a roof inclining direction, an overlap width C between the right and left roofings 30, and the number E of transversely arranged solar battery panels 1, the transverse width Z holds a following equation; Z = (B × n) - C × E/E. Then a longitudinal length Y is set equal to the gauge D of the roofing 30 or to the magnification of the gauge D, and the dimension of the solar battery panel 1 a predetermined dimension is set. Further the center of the solar battery panel 1 in a subsequent stage is set to the center of a gap between the right and left solar battery panels 1, and in this manner, surfaces of the solar battery panels 1 are set stepwise from an eaves side to a ridge side.
