DESCRIPTION OF THE BEST MODE FOR CARRYING OUT THE
INVENTION
Figure 1 Figure 1 shows a solar energy collection device 101 secured as part of a roof structure of a building 102. In this example, building 102 is an agricultural building, such as a barn. An array of solar energy collection devices may be secured as part of a roof of an agricultural building that has a surface area in the order of hundreds of square metres.
Solar energy collection device 101 forms part of an array of solar energy collection devices that are secured as part of a roof structure to provide a roof presenting an outer layer of solar energy collection devices. Roof 103 of building 102 comprises roof elements in the form of a plurality of rafters, such as rafter 104, and a plurality of purlins, such as purlin 105.
The solar energy collection device is secured so as to form part of roof 103. In this example, solar energy collection device 101 is substantially rectangular having short sides, such as short side 106, and long sides such as long side 107. Solar energy collection device 101 is oriented such that the short sides extend in the direction that the purlins extend, and the long sides extend in the direction that the rafters extend. This orientation is referred to herein as portrait'. In an alternative arrangement, the solar energy collection device is oriented such that the long sides extend in the direction that the purlins extend, and the short sides extend in the direction that the rafters extend. This orientation is referred to herein as landscape.
The integration of solar energy collection devices as part of a roof provides an architectural feature that also allows the building to generate electrical power. In many countries, local power generation from renewable sources is encouraged. In some instances, it is possible for a user to obtain payment for power supplied to an external source, such as a national grid, at a rate that is higher than the user must pay for receiving power from that external source. Consequently, a user may gain financially if the environment is optimised so as to maximise power generation while at the same time minimising power consumption.
Solar energy collection devices may form part of the roof of a new build or could be provided as the result of the repair or replacement of portions of an existing build. In this example solar energy collection device 101 is a photovoltaic device. However, solar energy collection device 101 may be a solar-thermal device.
Figure 2 Figure 2 shows installation apparatus 201 for use in securing a solar energy collection device as part of a roof. The term part of a roof' is used herein to generally describe the installation of solar energy modules as part of, rather than on top of, a roof. Typically, therefore, solar energy collection devices may be installed so as to be flush with common roofing materials.
Thus, for example, when installed as part of a roof, solar energy collection devices may be perceived as replacing the outermost layer of a roof structure, that presents the outer surface of the roof, and for example allows flashing to be used at interfaces in the normal way.
Installation apparatus 201 comprises a bracket element 202, an interface element 203, a mullion element 204, and a cap element 205.
However, it is to be appreciated that other elements, for example the components introduced below, may also form part of the installation apparatus, or used within an installation that utilises one or more sets of the installation apparatus.
Bracket element 202 is configured to be secured to a roof element of a roof structure and is configured to co-operate with interface element 203 to provide a first coupling arrangement. Mullion element 204 presents a support plane for receiving an edge of a solar energy collection device 101 thereon and to co-operate with interface element 203 to provide a second coupling arrangement. Cap element 205 is configured to be secured to mullion element 204 such that a received edge of a solar energy collection device 101 is secured between cap element 205 and the support plane of mullion element 204.
As will be described in further detail below, the first coupling arrangement is configured to allow adjustment, in a first direction 206, of interface element 203 relative to bracket element 202 for enabling the distance of a received edge of a solar energy collection device from the bracket element 202 to be adjusted. The second coupling arrangement is configured to allow a io degree of movement, in a second direction 207 that is substantially perpendicular to the first direction 206, of the mullion element 204 relative to interface element 203 for allowing a degree of movement of a received edge of a solar energy collection device relative to interface element 203.
The installation apparatus 201 is adaptable and flexible in terms of the types of buildings that it allows solar energy collection devices to be securable as part of the roof.
Figure 3 Figure 3 shows bracket element 202 in further detail. The bracket element comprises a base element 301 configured to be secured to a roof element of a roof structure. Base element 301 defines a plurality of apertures, such as aperture 302 and aperture 303. Bracket element 202 also comprises a prop element 304 extending from the base element 301, substantially perpendicularly thereto and presenting a free end 305.
Figure 4 Figure 4 shows bracket element 202 secured to a roof element 401 by means of a mechanical fixing 402. The type of roof element forming part of a roof structure may vary between buildings. For example, a roof beam may be fabricated from wood or steel and may be a box-section, an I-section, a J-section or a Z-section type beam. Thus, beams may vary in material, shape and size. The bracket element 202 of the installation apparatus provides for attachment to a variety of types of roof beams. In addition, the bracket allows for different mechanical fixings, for example U-bolts, to be used on the same roof. This feature facilitates installation on a roof that has an inconsistent roof structure. An inconsistent roof structure may result from ageing, from the replacement or retrofit of a roof element or generally from the use of different io types of roof element in the roof structure. Thus, overall, the arrangement of the bracket increases the applicability of the installation apparatus and in turn allows more buildings to utilise solar technology.
In this illustrated example, mechanical fixing 402 comprises a U-bolt configured to extend around roof element 401 with each free end extending through an aperture in base element 301 of bracket element 202, with first and second threaded nuts employed to connect the U-bolt to the bracket element.
Any suitable alternative type of mechanical fixing may be used. By providing the bracket element with more than two apertures in a row, for example to provide a variety of distances between apertures andlor to provide apertures of different diameters, the bracket element 202 may be rendered suitable for use with a variety of different roof beams. This feature enables the bracket element to be more widely utilisable in the securing of solar energy collection devices as part of a roof. Thus, in some instances, brackets of the same type that are located along the same roof element may be fixed to that roof element by use of different apertures.
Figure 5 Figure 5 shows interface element 203 in further detail. Interface element 203 comprises a platform 501 having an upper face 502 and a lower face 503.
Upper face 502 presents a slot, indicated at 504, that extends in a third direction 505. Lower face 503 presents a pair of extension members 506, 507 extending from the lower face 503 substantially perpendicularly to the lower face 503. In this example, extension members 506, 507 take the form of a pair of substantially parallel rails. As can be seen, in this example, rails 506, 507 extend substantially in the direction 505 of slot 504. In this example, the third io direction 505 is perpendicular to both the first direction and the second direction of the first coupling and the second coupling provided by the installation apparatus.
Figure 6 Figure 6 shows an interface element arrangement 601 comprising interface element 203 and a second interface element 602. In this example, interface element 602 is identical to interface element 203. As shown, within the arrangement, the first and second interface elements 203, 602 are arranged adjacently, in other words side by side, and in opposite orientation such that the first and second pairs of extension members are aligned and the first and second slots face each other. The interface elements 203, 602 may be secured together. A mechanical fixing, such as a cable tie,.may be used to secure two interface elements in an interface element arrangement as shown.
However, any suitable alternative type of connecting means may be used.
Figure 7 Figure 7 shows an interface element 701. Interface element 701 is similar to interface element 203 however the upper face presents a second slot that faces the first slot.
In this illustrated example, second slot 702, and similarly the facing slot, each take the form of a return edge, in other words, the edge of the interface element is bent back upon itself to provide the slot. However, any suitable alternative arrangement to provide the first and second facing slots may be employed.
Figure 8 Figure 8 shows apparatus 801 for use in securing a solar energy collection device as part of a roof structure. Apparatus 801 comprises bracket io element 202 and interface element 203. Bracket element 202 and interface element 203 are configured to co-operate to provide a first coupling arrangement, as shown. The pair of extension members 506, 507 of interface element 203 is configured to straddle prop element 304 of bracket element 202 with an interference fit. The first coupling arrangement allows adjustment in first direction 206 of interface element 203 relative to bracket element 202.
The first coupling arrangement allows the depth, indicated generally at 802, of apparatus 801 to be adjusted. The interference fit allows the coupling to be maintained once arranged as desired. The interference may be used as a temporary fixing, with a mechanical fixing being used to provide a subsequent permanent fixing.
Figure 9 Figure 9 shows mullion element 204 in further detail. Mullion element 204 comprises a base member 901 and a support element 902 extending from base member 901 substantially perpendicularly thereto. Mullion element 204 also presents at least one support plane 903 for receiving an edge of a solar energy collection device thereon. The base member 901 may be attached to a bracket element or directly to a roof element, in particular to a timber roof element.
In the installed arrangement, the mullion element is oriented to extend in the direction of the slope of the roof, typically from the ridge to the eaves. As will be described in further detail below, the mullion element is configured to receive water from other elements of the installed roof arrangement and direct received water towards the roof eaves and gutters.
Figure 10 Further features of mullion element 204 are illustrated in Figure 10.
According to this illustrated embodiment, support element 902 defines a hollow interior 1001 and also defines a first tab 1002 and a second, opposed, tab 1003 that extend inwardly into the interior chamber 1001 towards each other.
As shown, mullion element 204 is configured to receive a box section beam 1004 within hollow interior 1001 such that the beam 1004 is located to the side of tabs 1002, 1003 towards base element 901. Box section 1004 provides a joiner piece useful for providing further stability to the overall assembly of installation apparatus 201.
The mullion element defines at least one gutter, such as gutter 1005 for directing received water or other liquid away, down the slope of a roof towards the gutters. The mullion element also defines at least one screw flute, such as screw flute 1006, to enable further component pieces to be attached to the overall assembly of apparatus 201 if desired. Mullion element also defines a screw guide 1007 for receiving a mechanical fixing, such as a self-drilling screw, used to secure a cap element thereto. The mullion element may define drill lines, such as drill line 1008, to facilitate direct fixing to a timber roof. The mullion element may define a channel, such as channel 1009, shown in this illustration beneath support plane 903, for an optional rubber gasket or seal.
The curved surface of the channel 1009 facilitates the application and smoothing of gasket tape. Such a seal may be utilised to improve the weatherproofing of the internal space of the roof. The base element 901 has a flat lower surface that again facilitates the application of gasket tape to contribute to overall weatherproofing. The mullion element may define a groove, such as groove 1010, for fixing a joiner piece. Thus, the mullion piece is designed to provide a combination of features.
io Figure 11 Figure 11 shows apparatus 1101 for use in securing a solar energy collection device as part of a roof structure. Apparatus 1101 comprises interface element 203 and mullion element 204. Interface element 203 and mullion element 204 are arranged to provide a second coupling arrangement, as shown. It can be seen that, in the arrangement of Figure 11, base element 901 of mullion element 204 is held between the facing slots of interface element 203 such that a degree of movement is allowed in second direction 207. In the shown arrangement, the mullion element may be perceived as being gripped by the interface element in a way that allows a degree of movement in the second direction. It is to be understood that the degree of movement allowed in second direction 207 is small relative to the range of adjustment allowed in the first direction by the first coupling arrangement described above.
The second coupling arrangement allows the installation apparatus to accommodate movement of an edge of a solar energy collection device received on the mullion element. Such movement may occur as a result of thermal expansion or contraction of a solar energy collection device once secured as part of a roof. In addition, the degree of movement allowed by the second coupling may facilitate fine alignment of solar energy collection devices within an array during the installation process. Thus, the amount of movement allowed in the second direction is configured to accommodate a tolerance range associated with solar energy modules and will also forgive a degree of misalignment of bracket elements fixed to the roof structure. In addition, the interface element allows for thermal expansion and contraction of the mullion element in the third direction.
Figure 12 io Cap element 205 is shown in further detail in Figure 12. Cap element takes the form of a strip, having an upper face 1201 and a lower face 1202.
Lower face 1202 presents a pair of location members 1203, 1204 extending from lower face 1202 substantially perpendicularly to lower face 1202.
Figure 13 Figure 13 shows bracket element 202, interface element 203 and mullion element 204 arranged to provide a first coupling, indicated at 1301 and a second coupling indicated at 1302. In this illustration, an edge 1303 of a solar energy collection device is received relative to mullion element 204.
First coupling arrangement 1301 is configured to allow adjustment, in first direction 206, of interface element 203 relative to bracket element 202 for enabling the distance of received edge 1303 from bracket element 202 to be adjusted in first direction 206. Second coupling arrangement 1302 is configured to allow a degree of movement, in second direction 207, of mullion element 204 relative to interface element 203 for allowing a degree of movement of received edge 1303 relative to interface element 203 in second direction 207. As previously described, the first direction and a second direction are substantially perpendicular to each other. The first and second couplings provide the installation apparatus with a degree of adjustability in first and second directions that enables a variety of roofs to be provided with solar energy collection devices secured as part of the roof. It is to be appreciated that the specific number, type and arrangement of components of the installation apparatus may vary between applications. It is to be understood that the installation apparatus illustrated in the accompanying Figures allows for a degree of adjustment during installation and following to installation. The exact range of adjustment allowed by each of the first coupling and the second coupling may vary between applications.
Figure 14 Figure 14 illustrates solar energy collection device 101 in further detail.
The solar energy collection device 101 comprises a rigid frame 1401. The rigid frame 1401 is four-sided and, as previously described, provides a pair of short edges, such as short edge 106 and a pair of long edges, such as edge 107.
When installation apparatus 201 is in use, edges of the solar energy collection device that are received upon mullion elements. The received edges may be the edges of the long sides or the short sides of a solar energy collection device. Thus, rectangular solar energy collection devices may be installed as part of a roof structure in portrait or landscape orientation. When a rectangular solar energy collection device is installed, each of a pair of edges of the solar energy collection device extends along a mullion element whilst each of the other pair of edges of the solar energy collection device extends between mullion elements. It is, however, anticipated that the most common orientation will be the portrait orientation.
In the arrangement shown in Figure 14, the long edges of rigid frame 1401 extend along mullion elements and the short edges extend between mullion elements.
A bridging element 1402 is shown. In this illustration, bridging element 1402 is shown located relative to an edge of solar energy collection device 101. The bridging element 1402 is configured to extend over the edges that extend between mullion elements, not the edges that extend alon.g mullion elements, onto rigid frame 1401 and is also configured to present a further portion configured to extend over the rigid frame of a further like solar energy collection device 1403. Bridging element 1402 is configured to clip onto solar energy module frames. In this way, the bridging element 1402 is arranged to hang off a solar energy collection device and present a region into which another solar energy collection device can be located.
Thus, in the installed arrangement, such as that presented in Figure 1, cap elements receive edges of adjacent solar energy collection devices that extend along mullion elements and bridging elements receive edges of adjacent solar energy collection devices that extend between mulUon elements.
The bridging elements are configured to direct water to the mullion elements, which in turn are configured to direct water away to the roof gutters along the eaves. Thus, as shown in Figure 14, mullion element 204 provides a gutter, such as gutter 1005, that extends underneath received solar energy collection devices in order to direct water, illustrated at 1404, away towards the roof gutters. Thus, the installation apparatus 201 provides paths or routes to receive water and to direct that water to flow away from received moisture sensitive solar energy collection devices and away from the interior of the roof.
Overall, the apparatus 201 provides for an increased degree of weather tightness, and waterproofness, to the installed array of solar energy collection devices and the roof. The adjustability of the apparatus 201 allows an installer to make adjustments to assist in the presentation of an array of solar energy modules as part of a roof with minimised gaps that would allow moisture/dirt ingress Figure 15 Figure 15 shows steps in a method of using installation apparatus for installing a solar energy collection device as part of a roof. At step 1501, a bracket element is secured to a roof element. At step 1502, an interface element is arranged relative to the secured bracket element to provide a first coupling. At step 1503, the first coupling is adjusted. This adjustment allows for mullion elements in an installation to be levelled on the roof, When the desired relative arrangement is achieved, the first coupling is then fastened. Fastening may be achieved by use of a mechanical fixing such as a self-drilling screw.
However it is to be understood that, as previously described, the first coupling may be achieved by way of an interference fit such that a desired relative arrangements may be achieved and maintained without the use of a mechanical fixing to fasten the two together. This feature serves to facilitate the assembly of the apparatus.
At step 1504 a mullion element is arranged relative to the interface element to provide a second coupling. Again, it is to be appreciated that the second coupling allows the mullion element to be retained by the interface element without the need for a mechanical fixing to fasten the two together.
* Again, this feature also serves to facilitate the assembly. A solar energy collection device is arranged, at step 1505, relative to the mullion element. As previously described, the mullion element presents a support plane for receiving an edge of a solar energy collection device, the support plane acting as a ledge. The received edge may be the edge of a long side or a short side of a rectangular solar energy module. At step 1506, a cap element may then be arranged relative to the received solar energy collection device and the mullion element, in order to secure the solar energy collection device between the cap element and the mullion element. Thus, the arrangement provides for the solar energy collection device to be secured to the building roof structure without a direct fixing between the solar energy collection device and any of the components of installation apparatus 201. It is to be appreciated that in some instances, the cap element may only be arranged when adjacent solar io energy collection devices are installed. At step 1507, a bridging element may then be arranged relative to the solar energy collection device. Again, a direct fixing between the bridging element and the solar energy collection device is not required. In a similar manner to the cap element, the bridging element may only be arranged after adjacent solar energy collection devices have been installed. The installation steps are repeated to complete the desired installation.
Figure 16 Figure 16 shows installation apparatus 201 assembled to secure solar energy collection device 101 to a roof element. The roof slope direction is indicated by arrow 1601. Roof element 1602 is a purlin. In the shown arrangement, the solar energy collection device 101 is in the portrait orientation relative to the roof slope direction 1601. According to the shown arrangement, roof element 1602 slopes to make an angle 1603 with horizontal plane 1604. The solar energy collection device 101 also slopes and makes an angle 1605 with the horizontal planel 606. Horizontal plane 1604 and 1606 are parallel to each other. Thus, it is to be understood that, the installation apparatus 201 is configured such that solar energy collection device 101 is secured to extend parallel to roof element 1602, such that angle 1603 and 1605 are the same.
It is to be appreciated that the installation apparatus provides for a convenient means by which solar energy collection devices are securable to a building as part of the roof of that building. The component bracket element, interface element, mullion element and cap element of the installation apparatus may each be fabricated from metal. The manufacture of the components may comprise an extrusion process. The particular dimensions of each component and features of the component may vary between applications. The installation apparatus described herein is suitable for use on a variety of roofs having different surface areas.
