  • solar roof panel is understood herein to mean a panel that can convert solar energy into another form of energy, such as electrical or thermal energy, and can be mounted to a roof of a building.
  • one type of solar roof panel of interest to the applicant includes a photovoltaic cell module for converting solar energy into electrical energy.
  • the present invention also relates particularly although by no means exclusively to a system for generating electrical energy from solar energy using the solar roof panel mounted on the roof cladding sheet.
  • the roof of a residential or a commercial building is a convenient surface for mounting a solar energy conversion unit for converting solar energy into electrical energy and/or thermal energy that can be used in the building and/or a local electricity network.
  • the following description of the background art and of the invention focuses on but is not confined to this function of a roof. More specifically, the invention is not confined to providing a surface for mounting a solar energy conversion unit.
  • roof cladding sheets for a residential building are custom-cut to a 5 length required to cover a distance from an eave to a ridge of a roof. This eliminates a number of joins in the roof sheets, particularly along the sheet length.
  • custom-cutting sheets to length can have an impact on cost.
  • BIPV Building Integrated
  • the present invention provides a roof that includes a roof frame and a plurality 5 of roof cladding sheets secured to the roof frame, with the roof frame including a
  • trusses extending between a gutter and a ridge of the roof and a plurality of horizontally-extending battens secured to the trusses, with the roof cladding sheets extending horizontally across the roof and secured to the trusses and supported by the battens.
  • the battens make it possible for the roof cladding sheet to be formed with a wide flat pan as a non-structural member in the sense that it is not necessary for the roof cladding sheet to be formed to be the sole support for the weight of a person standing in the centre of the wide pan on the sheet when the sheet is secured to the trusses of the roof frame, for example when the trusses are spaced apart in accordance with building industry standards.
  • the battens provide the additional support required so that the assembly of the trusses, the battens and the roof cladding sheets can support the weight 5 of a person standing on the sheets without significant deformation of the sheets.
  • the combination of the trusses and the battens provides effective support for the roof cladding sheets (in combination with the structural capacity of the cladding sheets, bearing in mind the above comment that the sheets can be a non-structural member) and provides an opportunity for a roof to be constructed that can carry a o trafficable load on the roof cladding sheets. This is an advantage in terms of installation of the roof cladding sheets on the roof frame.
  • the battens are advantageous in relation to the end lap or join between successive roof cladding sheets across a roof.
  • the end lap or join is a potential weak spot of the roof in that it may not be able to support the same load as the roof5 cladding sheets.
  • the roof cladding sheets would need to be of larger cross sectional stiffness or the end lap or join would need to coincide with a truss (which may be described as a rafter).
  • the battens enable the end lap or join to be placed between truss frames, with the end lap or join being supported directly by the battens.
  • the battens and the roof cladding sheets may be positioned so that the battens are mid- way between the sides of the roof cladding sheets.
  • the battens may be secured to the trusses of the roof frame by any suitable fastener systems.
  • the battens may be formed from any suitable material.
  • the battens may be any suitable length and any suitable width and any suitable profile.
  • the battens do not cover a significant part of the surface area of the roof.

In this reference, the battens are provided in large part 0 for the safety of roof installers working on a roof during the installation of the roof.
  • the prior art battens cover a substantial part of the surface area of the roof and form a barrier to installers falling through the roof. This is not a primary driver for the battens of the invention.
  • the primary function of the battens is to act as structural members to support roof cladding sheets.
  • the battens cover no more than 30%, typically no more than 25%, of the surface area of the roof.
  • the battens may be formed from steel strip.

  • Each batten may be formed so that when the batten is secured to the trusses, the o fiat mounting surface of the rib or ribs forms a plane that is at a required angle to the trusses for securing the roof cladding sheets to the roof frame.
  • the roof may include a spacer member setting the spacing of the battens with respect to each other.
  • the time required for installing the battens can be reduced by means of the5 spacer members.
  • the spacer members can be left in place to provide additional support for the roof cladding sheets, particularly at the end laps.
  • the spacer members can be removed after the battens are installed on an underlying roof frame structure.
  • the spacer member may extend between and be secured to adjacent battens and o thereby set the spacing of the battens with respect to each other.
  • the spacer member may be detachably secured to the battens.
  • Each spacer member may have ends that are shaped to conform to a least a section of the profile of the battens so that the ends overlie the sections of the battens.

  • the first sheet may be a narrower profiled sheet, whereby the reinforcing rib is located close to the gutter line. The reinforcing ribs of the sheets in this first line provide effective reference points for locating the next line of roof cladding sheets on the roof frame.
  • each roof cladding sheet in the next line of sheets is positioned to overlie the reinforcing ribs of the roof cladding sheets in the first line of sheets and thereby provide continuous coverage at the overlap.
  • the reinforcing ribs of the roof cladding sheets in the first line of sheets cooperate with the downturned lips of the roof cladding sheets in the next line of sheets to locate the next line of sheets on the roof frame.

  • the reinforcing ribs 25 and the downturned lips 27 of the roof cladding sheets 9 o are also advantageous components because installing roof cladding sheets 9 with the downturned lips 27 of the sheets on the gutter line provides an opportunity, in conjunction with the flashing sheet 11, to close the roof at the gutter line and minimise the risk of ember entry into a roof space at the gutter line of the roof.
  • the combination of the reinforcing ribs 25 of the roof cladding sheets 9 and the battens 19 and the trusses 19 of the roof frame provides effective support for the roof cladding sheets 9 on the roof frame and provides an opportunity for a roof to be constructed that can carry a trafficable load in situations where the roof cladding sheets 9 are not structural members. This is an advantage in terms of installation of the roof cladding sheets 9 on the roof frame.
  • roof cladding sheets 9, in conjunction with the battens 19 of the roof frame can be used without the support of plywood or other structural sheeting substrate that is required for other horizontal roof cladding sheet systems known to the applicant.
  • roof cladding sheets 9 can be manufactured as modular, i.e. preset stock, lengths and hence can be manufactured to stock, with a small selection of stock lengths, ahead of time and drawn from that stock as required. This enables shorter lead times to meet customer requirements.
  • the invention is not limited to this arrangement and extends to other arrangements such as tongue and slot arrangements in the ends of the spacer members 43 and in the battens 19.
  • the battens 19 may be formed with a series of slots in the ribs 61 of the battens 19 at spaced intervals along the length of the ribs and the ends of the spacer members 43 may be formed with tongues that can extend into the slots to interconnect the battens 19 and the spacer members 43.
