Here, there is a case where it is desired to attach a solar panel to a roof having a roof structure as described in Patent Document 1 in which a new roofing material is arranged so as to cover the existing roofing material. However, when installing a fixing base for fixing the solar panel to the newly installed roofing material that was installed later, it is difficult to stably install the fixing base unless the strength of the installation of the new roofing material is secured. Therefore, the strength of mounting the fixing base for fixing the solar panel may be weakened.

Further, when a fixing base for fixing the solar panel is attached to the existing roofing material arranged below the newly installed roofing material, it is fixed to the flat portion of the slate as in the solar panel mounting structure described in Patent Document 2. If the structure is such that the base is attached, the fixed base can be attached stably. On the other hand, it may be necessary to attach a fixing base to the stepped portion of the overlapping portion of the plurality of slate. When attaching the fixing base to the stepped portion of multiple slate, it becomes difficult to stably attach the fixing base to the stepped portion of multiple slate, and the mounting strength of the fixing base for fixing the solar panel becomes weak. there is a possibility.
Therefore, in a roof structure in which a new roofing material is arranged so as to cover an existing roofing material, it is desired that the solar panel can be stably installed when the solar panel is installed.

Next, the solar panel mount 52 (see FIG. 1) is attached to the mount mounting bracket 51 fixed to the upper surface of the panel side mounting plate portion 37 of the first support bracket 3, and the photovoltaic power generation panel 53 is attached to the solar panel mount. Attach to 52. As a result, the photovoltaic power generation panel 53 is attached to the first support metal fitting 3 (solar panel attachment step).

According to the first embodiment, the following effects are achieved.
In the solar panel mounting structure 1 of the present embodiment, the existing first roofing material 13 provided with the stepped portion 14 having the upper stepped surface 141 and the lower stepped surface 142 and the first roofing material 13 are arranged so as to cover them. A second roofing material 4 to be newly installed, a photovoltaic power generation panel 53 arranged above the second roofing material 4, a support member 3 for supporting the second roofing material 4 and the photovoltaic power generation panel 53, and a first In the fixing base 22 to which the support metal fitting 3 is fixed, in the step portion 14 of the first roofing material 13, a part on the ridge side is arranged on the upper step surface 141 and the other part on the eave side is the lower step surface 142. A fixed base 22 arranged apart from the fixed base 22 and a spacer member 23 arranged between the fixed base 22 and the lower step surface 142 are provided.

Therefore, since the fixing base 22 can be supported by the spacer member 23 at the stepped portion 14 of the existing first roofing material 13, the fixing base 22 can be stably installed on the existing first roofing material 13. As a result, the photovoltaic power generation panel 53 can be stably installed.

Further, in the present embodiment, the end side spacer member 231 and the center side spacer member 232 are arranged inside the both ends of the fixing base 22 in the direction intersecting the inclination direction of the first roofing material 13.

Here, tentatively, in the direction intersecting the inclined direction of the first roofing material 13, the end portion of the end side spacer member 231 protrudes outside from both ends of the first roofing material 13 of the fixing base 22 or When arranged at overlapping positions, the water flowing downward in the inclination direction of the first roofing material 13 is transmitted under the end portion of the end side spacer member 231 and under the fixing base 22 (with the fixing base 22). It will wrap around to the second waterproof sheet 21). On the other hand, in the present embodiment, the end side spacer member 231 and the center side spacer member 232 are arranged inside both ends of the fixing base 22 in the direction intersecting the inclination direction of the first roofing material 13. As a result, the water flowing downward in the inclination direction of the first roofing material 13 is suppressed from being transmitted to the end portion of the end side spacer member 231 and is under the fixing base 22 (fixing base 22 and the second waterproof sheet 21). It is suppressed to wrap around. Thereby, the watertightness can be improved.
