Abstract

This photovoltaic power generation device is provided with: a mounting bracket which is fixed to a roof and on which a frame, arranged on the ridge-side end of a solar cell module, and a frame, arranged on the eave-side end of a solar cell module, are mounted; and a fixing bracket which is arranged in the space between the frame and the frame, and which is fixed to the mounting bracket and holds said frames from above.

First claim

The invention claimed is:

1. A photovoltaic power generation device comprising:
a first solar cell module including a first solar cell panel and a first frame installed at an edge portion of the panel;
a second solar cell module including a second solar cell panel and a second frame installed at an edge portion of the panel, the second solar cell module being disposed next to and on a ridge-side of the first solar cell module with a space therebetween;
a mounting bracket to be fixed to a roof, the mounting bracket allowing a part of the first frame that is installed at a ridge-side edge portion of the first solar cell module, and a part of the second frame that is installed at an eave-side edge portion of the second solar cell module, to be mounted thereon; and
a fixing bracket disposed at the space to straddle between the first frame and the second frame, the fixing bracket being fixed to the mounting bracket to press the frames from above,
wherein the photovoltaic power generation device further comprises a base bracket to which a bolt for fixing the fixing bracket is fastened,
the mounting bracket includes a guide rail portion that slidably supports the base bracket such that the base bracket is slidable along a eave-ridge direction of the roof,
the fixing bracket is fixed to the mounting bracket via the base bracket inserted into the guide rail portion, and
wherein the first frame includes a first inner flange portion extending to an inner side of the first solar cell module, and
the base bracket includes an engaging portion that protrudes higher than the top of the mounting bracket and engages with the first inner flange portion.

2. The photovoltaic power generation device according to claim 1 ,
wherein the second frame includes a second inner flange portion extending to an inner side of the second solar cell module, and
the base bracket includes a ridge-side wall portion that protrudes higher than the top of the mounting bracket and is disposed to oppose an edge of the second inner flange portion.

3. The photovoltaic power generation device according to claim 1 , wherein
the photovoltaic power generation device further comprises a cover that is provided across the space to straddle between the first frame and the second frame, and is attached on the fixing bracket.

4. The photovoltaic power generation device according to claim 1 , wherein
the photovoltaic power generation device further comprises a cover that is provided across the space to straddle between the first frame and the second frame, and is attached on the fixing bracket
the first frame includes a first outward groove that outwardly opens from the first solar cell module, and
the photovoltaic power generation device further comprises a support bracket that is fixed to the first frame by being inserted into the first outward groove, and the cover is screwed to the support bracket.

5. The photovoltaic power generation device according to claim 1 , wherein
the base bracket includes at least one wall portion that protrudes higher than the top of the mounting bracket and are disposed in the space between the first solar cell module and the second solar cell module, and
the fixing bracket includes at least one slit into which the at least one wall portion is inserted.

6. The photovoltaic power generation device according to claim 1 , wherein
the photovoltaic power generation device further comprises a guide member that guides the bolt to a fastening spot of the base bracket, and
the guide member is disposed on the base bracket and inserted into the guide rail portion of the mounting bracket.

7. A photovoltaic power generation device comprising:
a first solar cell module including a first solar cell panel and a first frame installed at an edge portion of the panel;
a second solar cell module including a second solar cell panel and a second frame installed at an edge portion of the panel, the second solar cell module being disposed next to and on a ridge-side of the first solar cell module with a space therebetween;
a mounting bracket to be fixed to a roof, the mounting bracket allowing a part of the first frame that installed at a ridge-side edge portion of the first solar cell module, and a part of the second frame that is installed at an eave-side edge portion of the second solar cell module, to be mounted thereon; and
a fixing bracket disposed at the space to straddle between the first frame and the second frame, the fixing bracket being fixed to the mounting bracket to press the frames from above, wherein
the photovoltaic power generation device further comprises a base bracket to which a bolt for fixing the fixing bracket is fastened,
the mounting bracket includes a guide rail portion that slidably supports the base bracket such that the base bracket is slidable along an eave-ridge direction of the roof, and
the fixing bracket is fixed to the mounting bracket via the base bracket inserted into the guide rail portion,
wherein the second frame includes a second inner flange portion extending to an inner side of the second solar cell module, and
the base bracket includes a ridge-side wall portion that protrudes higher than the top of the mounting bracket and is disposed to oppose an edge of the second inner flange portion.

8. The photovoltaic power generation device according to claim 7 , wherein
the first frame includes a first inner flange portion extending to an inner side of the first solar cell module, and
the base bracket includes an engaging portion that protrudes higher than the top of the mounting bracket and engages with the first inner flange portion.

9. The photovoltaic power generation device according to claim 7 , wherein
the fixing bracket includes at least one slit into which the at least one wall portion is inserted.

10. The photovoltaic power generation device according to claim 7 , wherein
the photovoltaic power generation device further comprises a guide member that guides the bolt to a fastening spot of the base bracket, and
the guide member is disposed on the base bracket and inserted into the guide rail portion of the mounting bracket.

11. The photovoltaic power generation device according to claim 7 , wherein
the photovoltaic power generation device further comprises a cover that is provided across the space to straddle between the first frame and the second frame, and is attached on the fixing bracket.
