In another aspect of the invention, there is provided a support assembly for a photoelectric cell assembly, the support assembly including (i) a sheet substrate that has oppositely facing surfaces, with one surface having a flat surface for mounting the
12252789_1 (GHMatters) P93848.AU.2 photoelectric cell assembly in the form of a flexible film for converting solar energy into electrical energy and electrical components for transferring electrical energy from the assembly for use in an electrical system of the building or a local electrical network and (ii) reinforcement members extending from the other surface for the substrate that stiffen the support assembly and are formed to facilitate locating the solar roof panel on one or more profiled roof cladding sheets, wherein the reinforcement members are elongate and extend at least part of the length of the substrate, the reinforcement members include side reinforcement members on both sides of the substrate and an intermediate reinforcement member positioned between the sides of the substrate.
The term “profiled roof cladding sheets” is understood herein to mean sheets which include one or more parallel ribs with opposed sides, pan sections, and side edge formations that enable the sheets to be positioned side by side in overlapping relationship. Roof cladding sheets may be roll-formed from painted or unpainted steel or aluminium strip or formed from extruded aluminium, carbon fibre, fibre glass or plastics material.
The solar roof panel may be any suitable length and width. By way of example, the length of the solar roof panel may be selected to extend between a ridge of a section of the roof and a gutter of the roof.

The flexible film may be a thin film of less than 3 mm thick.
The photoelectric cell assembly may include a photovoltaic cell module that includes a semi-conductor material electro-deposited or otherwise deposited on an electrically-conductive, such as stainless steel, flexible substrate and encapsulated in a moisture barrier laminate material.
The photoelectric cell assembly may include triple-junction solar cells made from semi-conductor material on a flexible laminate material.
The support assembly substrate may include at least two flat surfaces that are spaced apart along the length of the substrate, with a gap between the flat surfaces.

12252789_1 (GHMatters) P93848.AU.2
The substrate and the reinforcement members may be manufactured as separate components of the support assembly and assembled together, for example by being adhered together.
The substrate and the reinforcement members of the support assembly may be integrally-formed from a single sheet of material.
The substrate and the reinforcement members may be made from any suitable material. Steel is one such suitable material.
When the substrate is a flat steel sheet, typically the steel is a low carbon steel.

When the substrate is a flat steel sheet, typically the steel has a metal alloy coating to resist corrosion.
When the substrate is a flat steel sheet, typically the steel is a low carbon steel with a metal alloy coating and a painted top coating to resist corrosion and improve aesthetics.
The reinforcement members may be formed to facilitate locating the solar roof panel on ribs of profiled roof cladding sheets.
The support assembly may include a plurality of parallel intermediate reinforcement members positioned between the sides of the substrate.
The spacing of the parallel intermediate reinforcement members may be equal to or a multiple of the spacing of adjacent ribs of profiled roof cladding sheets. Typically, the spacing is twice the rib spacing.
Each intermediate reinforcement member can facilitate locating the solar roof panel on one or more profiled roof cladding sheets by being formed as an elongate channel having a central web secured to the substrate and a pair of side walls extending from opposite side edges of the web away from the substrate that, in use, can be located over a rib of a profiled roof cladding sheet.
Each intermediate reinforcement member may include a flange extending outwardly from each side wall. This arrangement may be described as a top hat profile.
The support assembly may include stiffening ribs, typically small stiffening ribs, on the surface of the substrate on which the photoelectric cell assembly and therefore

The solar roof panel and the roof cladding may define a plurality of elongate ducts extending along the length of the solar roof panel, each of which ducts has an inlet at one end and an outlet at the other end for air flow along the length of the ducts.
Typically, the air flow is upward flow from a gutter end to a ridge end of the solar roof panel.
The air flow provides an opportunity to cool the solar roof panel via heat transfer from the panel to air that flows through the ducts. The efficiency and operating life of photovoltaic cells decreases with temperature and hence heat removal is an important consideration for maintaining high efficiency operation and optimum operating life of the solar roof panels. Moreover, the heated air provides an opportunity to provide heated air for use in the building to improve energy efficiency in the building.
12252789_1 (GHMatters) P93848.AU.2

DESCRIPTION OF EMBODIMENTS
Figure 1 illustrates an A-frame roof section of a building with five solar roof panels 3 in accordance with one embodiment of the invention mounted to each side of the roof and forming a solar energy conversion unit.
The roof section shown in Figure 1 is by way of illustration only and the invention is not confined to A-frame roofs and to the specific number of solar roof panels 3 on the roof.
The solar roof panels 3 extend down the sides of the roof between a ridge 5 and gutters 7 of the roof. The solar roof panels 3 are located on profiled roof cladding sheets 9 (see Figures 3, 7, 8, and 9) by means of fasteners (not shown). The profiled roof cladding sheets 9 are mounted via fasteners (not shown) to purlins 11 that form a part of the A-frame of the roof - see Figures 1 and 2. The upper ends of the solar roof panels 3 are formed to extend under a ridge cap 45 on the ridge 5.
The roof cladding sheets 9 may be of any suitable profile that includes ribs that extend from pan sections of the sheets 9. With reference to Figures 3, 7, 8, and 9, the roof cladding sheets 9 are roll-formed from sheet steel and optionally include a corrosion resistant metal alloy coating and a painted outer coating and include ribs 13 separated by pans 15. The cladding sheets 9 may be of any suitable length and width and may include any suitable number of ribs 13 and pan sections 15. In the arrangement shown in the Figures, there are six pan sections 15 and seven ribs 13. Each rib 13 includes two sides 17 separated by a slightly convex upper section 18.
Each solar roof panel 3 includes:
(a) a photoelectric cell assembly for converting solar energy into electrical energy, and (b) a support assembly for the photoelectric cell assembly.
The photoelectric cell assembly of each solar roof panel 3 includes two separate thin, flexible photovoltaic cell modules 19, with each module 19 including (i) photovoltaic cells mounted on a suitable laminate and forming a thin photovoltaic cell/laminate sheet 33 and (ii) electrical components in the form of wiring junction boxes 28 and electrical cables 31 for transferring electrical energy from the assembly for use in an electrical system (not shown) of the building or to a local electrical
12252789_1 (GHMatters) P93848.AU.2 network. The invention is not confined to the use of two separate modules 19 and extends to any suitable number of modules 19, including a single module 19.
With reference to Figure 4, the photovoltaic cell/laminate sheets 33 are mounted to the support assembly by adhesive tape or other suitable mounting option. The sheets 33 are 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 and adjacent the gap 35. The sheets 33 are also positioned so that there is a space 37 at an upper ridge end of the support assembly and a space 39 at a lower gutter end of the support assembly. Electrical components are positioned in and adjacent the spaces 37, 39.
The solar roof panel 3 includes elongate covers 41 (see Figure 1, 4, and 5) that are mounted over the electrical components to protect the components.
With particular reference to Figures 2, 9, 10, and 11, the support assembly includes a sheet substrate 21 that is rectangular with a pair of parallel sides 23 and parallel ends 25 (one of which forms the ridge end 5 and the other of which forms a gutter end 7 of the solar roof panel 3). The substrate 21 is a flat surface that has oppositely facing flat surfaces. The photoelectric cell assembly is mounted on an “upper” (as viewed in the Figures) flat surface of the assembly.
The support assembly also includes side reinforcement members 29 and intermediate reinforcement members 27 on the “lower” (as viewed in the Figures) flat surface of the assembly. The reinforcement members 27, 29 stiffen the support assembly and are formed (particularly in the case of the reinforcement members 27) to facilitate locating the solar roof panel 3 on the ribs 13 of the roof cladding sheets 9.
The substrate 21 and the reinforcement members 27, 29 are manufactured from steel as separate components of the support assembly and are assembled together, for example by being adhered together.
The reinforcement members 27, 29 are elongate and extend substantially along the length of the substrate 21. The spacing of the intermediate reinforcement members 29 is twice the spacing of adjacent ribs 13 of roof cladding sheets 9, although the spacing may be any suitable multiple spacing of the rib spacing.
Each intermediate reinforcement member 27 facilitates locating the solar roof panels 3 on the profiled roof cladding sheets 9 by being formed as an elongate channel with a top hat profile that fits over the ribs 13 of the profiled roof cladding sheets 9. As
12252789_1 (GHMatters) P93848.AU.2 can best be seen in Figure 12, the channel includes: (a) a central web 51, (b) a pair of side walls 53 extending from opposite side edges of the web 51, and (c) a flange 55 extending outwardly from each side wall 53.
Each side reinforcement member 29 is an elongate channel that includes: (a) a pair of parallel sections 57 and a web 59 interconnecting the sections 57 (Figure 13).
As can best be seen in Figure 7, the solar roof panels 3 extend across the profiled roof cladding sheets 9, such that the solar roof panels 3 and the profiled roof cladding sheets 9 define a plurality of elongate ducts 61 extending along the length of the solar roof panels 3. Each duct 61 has an inlet at one end and an outlet at the other end for air flow along the length of the ducts. Typically, the air flow is upwardly inclined air flow via from the gutter end 7 to the ridge end 5 of the solar roof panel. As is indicated above, the air flow provides an opportunity to cool the solar roof panels 3 via heat transfer from the panels 3 to air that flows through the ducts 61. The efficiency and operating life of photovoltaic cells decreases with temperature and hence heat removal is an important consideration for maintaining high efficiency operation and optimum operating life of the solar roof panels. Moreover, the heated air provides an opportunity to provide heated air for use in the building to improve energy efficiency in the building.
The solar energy conversion unit formed from the array of solar roof panels 3 shown in Figure 1 is straightforward to retro-fit to an existing roof or to install as a part of a new build.
One assembly option for the solar energy conversion unit includes the following steps. The solar roof panels 3 are located on the profiled roof cladding sheets 9 by positioning the panels 3 so that the downwardly-opening channels of the intermediate reinforcing members 27 are located on the ribs 13 of the sheets 9. The channels of the intermediate reinforcing members 27 are a convenient and effective locating option. In this connection, the intermediate reinforcing members 27 do not have to be a close fit on the ribs 13, although they may be if required for a particular application. The side reinforcing members 29 essentially wrap over the opposed sides of the profiled roof cladding sheets 9 and facilitate further locating of the solar roof panels 3 in position. The solar roof panels 3 are fastened to the profiled roof cladding sheets 9 by means of fasteners (not shown). The fasteners may be any suitable fasteners. Typically, the solar
12252789_1 (GHMatters) P93848.AU.2
2018229533 03 Apr 2020 roof panels 3 are fastened through the ribs 13 of the sheets 9. The ridge cap 5 and the covers 41 are then positioned to complete the process.
As described above, the upper ends of the solar roof panels 3 are formed to extend under the ridge cap 45 on the ridge 5. As a consequence, the upper ends of the ducts 61 are under the ridge cap 45. The ridge cap 35 includes a conventional inverted V-shaped cover sheet 47 designed to keep rainwater out of a building and a plenum chamber 49 for collecting air flowing upwardly along the ducts 61 into the plenum chamber 49. The plenum chamber 49 runs across the roof and is typically a trapezoidal shape (although it could be any suitable shape), with one chamber 49a for one rooffacing direction and a separate chamber 49 for the other roof-facing direction so that air from a cooler side of the building can be used separately to that from a side of the building more directly facing the sun. These plenum chambers 49 can be fabricated out of steel or any other suitable material and typically are used to channel the air collected from the ducts 61 for use in the building - for heating or for cooling.
The plenum chambers 49 may be connected to an air handling system (not shown) that includes a fan (not shown) for forcing air flow, by one or more spigots (not shown) or other suitable elements along the plenum chamber length. The number of spigots is typically dependant on the fan size and length of the chamber and how the heated or cooled air will be used in the building.
The following product specification for the solar roof panel 3 is presented by way of example only.
