  The roof section shown in FIG. 1 is by way of example only, and the invention is not limited to the roof of the A-shaped frame and the solar roof panel 3 of a particular number of roofs.

  The photovoltaic roof panel 3 extends downward to the side of the roof between the roof ridge 5 and the ridge 7. The solar roof panel 3 is positioned by means of fasteners (not shown) on the profiled roof cladding sheet 9 (see FIGS. 3, 7, 8 and 9). The profiled roof cladding sheet 9 is attached to a purlin 11 which forms part of the A frame of the roof using fasteners (not shown) (see FIGS. 1 and 2).

The invention is not limited to the use of two separate modules 19 but extends to any suitable number of modules 19 including a single module 19.

  Referring to FIG. 4, the solar cell / laminate sheet 33 is attached to the support assembly by adhesive tape or other suitable attachment options. The sheet 33 is positioned with a gap 35 between the upper end of one sheet and the lower end of the other sheet. Electrical components are positioned in the gap 35 and also positioned adjacent to the gap 35. The seat 33 is also positioned such that there is a space 37 at the end of the upper ridge of the support assembly and a space 39 at the end of the lower ridge of the support assembly. Electrical components are positioned in spaces 37 and 39 and also adjacent to spaces 37 and 39.

  The solar roof panel 3 includes an elongated cover 41 (see FIGS. 1, 4 and 5) mounted over the electrical components to protect the components.

  In particular, with reference to FIGS. 2, 9, 10 and 11, the support assembly comprises a pair of parallel side surfaces 23 and parallel ends 25 (one of which forms the end 5 of the ridge of the solar roof panel 3) And the other comprises a sheet substrate 21 which is rectangular having a ridge end 7 of the solar cell roof panel 3). The sheet base 21 is a flat surface having opposing flat surfaces. The photovoltaic cell assembly is mounted in the plane "above" (seen in the figure) of the assembly.

Positioning the panel 3 positions the solar roof panel 3 in the profiled roof clad sheet 9 and the downwardly opening grooves of the intermediate reinforcement members 27 in the ribs 13 of the sheet 9. The groove of the intermediate reinforcing member 27 is a convenient and effective positioning option. In this connection, the intermediate reinforcing member 27 need not be a tight fit on the rib 13, but may be a tight fit if desired for a particular application. The side reinforcing members 29 essentially wrap around the opposite sides of the profiled roof cladding sheet 9 to facilitate further positioning of the solar roof panel 3 in the proper position. The solar roof panel 3 is fastened to the profiled roof cladding sheet 9 by fasteners (not shown). The fastener may be any suitable fastener. In general, the solar roof panel 3 is fastened by the ribs 13 of the sheet 9. Thereafter, ridge cap 5 and cover 41 are positioned to complete the process.

  As described above, the upper end of the solar cell roof panel 3 is formed to extend under the ridge cap 45 on the ridge 5. As a result, the upper end of the duct 61 is below the ridge cap 45. The wing cap 35 is a conventional inverted V-shaped cover sheet 47 designed to prevent rainwater from entering the building, and a plenum for collecting air flowing into the plenum chamber 49 upward along the duct 61. And a chamber 49. The plenum chamber 49 extends across the roof and is generally trapezoidal in shape (although it may be of any suitable shape), with one chamber 49a for one roof facing direction and the other With a separate chamber 49 for the roof facing direction, the air from the colder sides of the building can be used separately from the air from the side of the building that is more directly facing the sun. These plenum chambers 49 can be made of steel or any other suitable material and are generally used to direct the air collected from the ducts 61 used in the building for heating or cooling. Used.

  The plenum chamber 49 may be a fan (for example, a spigot (not shown) or other suitable element along the length of the plenum chamber to force air flow through the plenum chamber 49). (Not shown) may be connected to an air treatment system (not shown). The number of outlets is generally determined by the size of the fan and the length of the chamber, and how heated or cooled air is used in the building.
