TITLE: Assembly, solar panel device, support foot and method.
The present invention relates to an assembly comprising a solar panel device and at least a first support and a second support to support the solar panel device, in particular in an inclined position or vertical position. The invention further relates to a solar panel device, a 5 support foot to support one or more solar panel devices, and a method to install an assembly comprising a solar panel device and at least a first support and a second support.
Solar panel devices are more and more used for generating electrical energy from solar radiation. One of the reasons for the increasing use of solar panel devices is the decreasing costs for a solar panel device, since a substantial number of solar panel devices may be 10 required to generate sufficient energy.
In view thereof, there is a need for a solar panel support system which makes efficient mounting of solar panel device on a support surface, such as a roof surface, possible.
Many different embodiments of solar panel devices are known. These solar panel devices usually comprise a solar panel and a panel holder which provides constructive 15 support to the solar panel.
The panel holders of known solar panel devices usually comprise a stiff frame enclosing the peripheral edge of the solar panel, so that the solar panel is prevented from bending by the presence of the frame. The stiff frame is often embodied as an aluminum U-shaped or L-shaped profile which is placed over the whole peripheral edge of the solar panel.
20 A novel plate-shaped solar panel device is described and shown in co-pending PCT
application having application number PCT/NL2012/050294, the contents of which are herein incorporated by reference.
In this novel solar panel device, the solar panel is not enclosed by a frame, but the solar panel is held by a panel holder which is connected, for example glued to one side of the solar 25 panel. As a result, the peripheral edge of the solar panel is free from any stiff frame enclosing this peripheral edge of the solar panel. In this patent application, such solar panel device in which the peripheral edge is not enclosed by a stiff frame which provides constructive stiffness to the solar panel is also indicated as a frameless solar panel device. Therefore, a frameless solar panel device may comprise a frame-like construction in the panel holder not 30 enclosing the peripheral edge of the solar panel by a stiff frame.
In conventional solar panel support systems, the stiff frame enclosing the peripheral edge of the solar panel is used for mounting the solar panel on a number of supports, for example on four support feet. In a frameless solar panel device, such stiff frame enclosing -2- the peripheral edge of the solar panel is no longer present, and thus this frame cannot be used for mounting the solar panel on its supports.
Furthermore, in a frameless solar panel device, the dimensions of the panel holder in the directions parallel to the main plane of the solar panel are preferably smaller than the 5 dimensions of the solar panel, so that the surface of the solar panel is maximally used as an effective surface, i.e. a surface where solar cells are provided to generate electrical energy from solar radiation.
Since the panel holder is covered by the solar panel, efficient mounting of the frameless solar panel devices becomes more difficult.
10 It is an aim of the invention to provide a solar panel support system which makes efficient installation of solar panel devices possible. Further, it is an aim of the invention to provide a solar panel support system which makes efficient installation of frameless solar panel devices possible.
The invention provides an assembly comprising: 15 at least one substantially plate shaped solar panel device having a main plane comprising a solar panel and a panel holder holding the solar panel, the panel holder having a side wall and a bottom wall, and at least a first support and a second support to support the solar panel device, wherein the first support is configured to support a first end of the solar panel device, 20 and the second support is configured to support a second opposite end of the solar panel device, wherein the first support comprises a first support coupling element and wherein the second support comprises a second support coupling element, wherein the panel holder comprises at the first end a first end coupling element to 25 cooperate with the first support coupling element of the first support, and wherein the panel holder comprises at an opposite second end a second end coupling element to cooperate with the second support coupling element of the second support, wherein the first end coupling element comprises one or more side wall openings in or one or more side wall extensions on the side wall of the panel holder, and wherein the second 30 end coupling element comprises one or more bottom wall openings in or one or more bottom wall extensions on the bottom wall of the panel holder, wherein the first support coupling element comprises one or more first support extensions or one or more first support openings to cooperate with the one or more side wall openings or one or more side wall extensions, respectively, and 35 wherein the second support coupling element comprises one or more second support extensions or one or more second support openings to cooperate with the one or more bottom wall openings or one or more bottom wall extensions, respectively.

The solar panel support system of the present invention makes an efficient installation of solar panel devices, in particular frameless solar panel devices, possible by using a two-step movement of the solar panel device with respect to supports arranged on a support surface, for example a roof surface.
5 In a first step, a first coupling movement is performed in which the solar panel device is moved with respect to the respective support in a direction substantially parallel to the main plane of the solar panel device. In this first coupling movement, the first end coupling element of the panel holder and the first support coupling element of the first support are coupled with each other.
10 It is remarked that the main plane of the solar panel device, solar panel or panel holder is the plane in which the main or largest dimensions extend. For example, the main plane of a rectangular plate shaped solar panel device, having a length, a width and a height, wherein the length and width are substantially larger than the height, is formed by a plane extending in the length direction and the width direction of the solar panel device.
15 To create this coupling, the first end coupling element comprises one or more side wall openings in or one or more side wall extensions on the side wall of the panel holder, and the first support coupling element of the first support comprises one or more first support extensions or one or more first support openings to cooperate with the one or more side wall openings or one or more side wall extensions of the first end coupling element, respectively.
20 Since the one or more side wall openings or one or more side wall extensions are arranged on the side wall of the panel holder, a movement in a direction substantially parallel to the main plane of the solar panel device is suitable to create a coupling between the first end coupling element of the panel holder and the first support coupling element of the first support.
25 In a second step, a second coupling movement of the solar panel device is performed to couple the second end coupling element and the second support coupling element to each other. To create this coupling the second end coupling element comprises one or more bottom wall openings in or one or more bottom wall extensions on the bottom wall of the panel holder, and the second support coupling element comprises one or more second 30 support extensions or one or more second support openings to cooperate with the one or more bottom wall openings or one or more bottom wall of the second end coupling element, respectively.
In the second coupling movement the second end coupling element and the second support coupling element couple to each other by a movement with respect to each other in a 35 direction substantially perpendicular to the main plane of the solar panel device, wherein preferably the coupling between the first end coupling element of the panel holder and the first support coupling element of the first support is used as a pivot for moving the second end -4- coupling element and the second support coupling element in a direction towards each other substantially perpendicular to the main plane of the solar panel device.
Due to this two-step movement, the first coupling between the first end coupling element and the first support coupling element, is locked by the second coupling between the 5 second end coupling element and the second support coupling element, i.e. the first coupling cannot be released before the second coupling is released. This is advantageous as the first coupling may be more difficult to reach, in particular in the case of frameless solar panel devices, where the panel holder is completely covered by the solar panel.
Only locking of the second coupling will provide reliable lock-up of the solar panel 10 device in the first and second support.
It is remarked that the bottom wall is a wall of the panel holder that extends substantially parallel to the main plane of the solar panel at a side facing away of the solar panel. The solar panel is arranged, for instance glued or otherwise connected, on a top wall of the panel holder. The side wall is a wall connecting the top wall and the bottom wall, extending mainly 15 at an angle with respect to the main plane of the solar panel, preferably in a direction mainly perpendicular to the main plane of the solar panel.
In an embodiment, the one or more first support extensions or one or more side wall extensions extend in a direction substantially parallel to the main plane of the solar panel device, when supported, preferably in an inclined position ora vertical position, on the at least 20 two supports.
In an embodiment, the one or more second support extensions or one or more bottom wall extensions extend in a direction substantially perpendicular to the main plane of the solar panel device, when supported, preferably in an inclined position ora vertical position, on at least the first support and second support.
25 In an embodiment, the assembly comprises a locking device to lock the solar panel device in a supported position, in which the solar panel device is supported in the inclined position on at least the first support and second support. The locking device is preferably configured to lock the second coupling between the second end coupling element and the second support coupling element. As explained above, by locking the second coupling 30 between the second end coupling element and the second support coupling element, the first coupling between the first end coupling element of the panel holder and the first support coupling element of the first support may also be locked.
In an embodiment, the panel holder comprises at its opposite second end a side wall locking hole in the side wall and wherein the second support comprises a support locking 35 hole, wherein at least one of the side wall locking hole and the support locking hole is a through-going hole, and wherein, when the solar panel device is supported on at least the first support and the second support in the inclined position, the sidewall locking hole and the -5- support locking hole are axially aligned in a direction substantially parallel to the main plane of the solar panel device to receive a locking pin.
By placing a locking pin in the axially aligned side wall locking hole and support locking hole, the opposite end of the solar panel device cannot be moved in a direction substantially 5 perpendicular to the main plane of the solar panel device, and, as a result, the second coupling between the second end coupling element and the second support coupling element cannot be released.
In an embodiment, the assembly comprises a third support and a fourth support to support the solar panel device, 10 wherein the third support is configured to support, the first end of the solar panel device, and the fourth support is configured to support the second opposite end of the solar panel device, wherein the third support comprises a third support coupling element and wherein the fourth support comprises a fourth support coupling element, wherein the solar panel device comprises at the one side a third end coupling element to 15 cooperate with the third support coupling element of the third support, and wherein the solar panel device comprises at the opposite side a fourth end coupling element to cooperate with the fourth support coupling element of the fourth support, wherein the third end coupling element and the third support coupling element couple to each other with the first coupling movement substantially parallel to the main plane of the solar 20 panel device, and wherein the fourth end coupling element and the fourth support coupling element couple to each other with the second coupling movement substantially perpendicular to the main plane.
It is advantageous to support a solar panel device at least at the four corner areas. This can for example be realized by two supports, each supporting two corner areas of the solar 25 panel device, or by four supports, each supporting one corner area of the solar panel device.
It is also advantageous to use one support, for example a support foot, to support two or more solar panel devices. For example, one support may be used to support four corner areas of four different solar panel devices. Such support may be configured to support, in their inclined position, two lower ends of two solar panel devices, and two upper ends of two 30 other solar panel devices.
In an embodiment, at least one of the first support and second support comprises: a support foot body made of plastics material, said support foot body comprising two support pillars to support a solar panel device, connected by a bridge element connecting the two support pillars, and 35 an anchoring device to anchor the support foot body to a support surface, wherein the anchoring device comprises an anchor element to anchor the anchoring device to the support -6- surface and a transverse beam connected to the anchor element, and placed on the bridge element.
The support pillars are configured to support a solar panel device. Each support pillar may support a separate solar panel device or the support pillars may together support a 5 single solar panel device. Each support pillar may be, in particular when the assembly is placed on a horizontal or substantially horizontal support surface such as a flat roof surface, a low pillar having a relatively low height to support the solar panel device at the lower end in the inclined position, or the support pillar may be high pillar having a relative large height to support the solar panel device at the upper end in the inclined position.
10 Dependent on the height of the support pillar, i.e. a low pillar or a high pillar, the lower support coupling element or the upper support coupling element, may be provided on or near the top end of the support pillar.
An anchoring device comprising a transverse beam is provided to anchor the support pillars to the support surface. The anchoring device comprises a anchor element which can 15 be anchored on the support surface and a transverse beam placed on the bridge element that connects the two pillars to each other. This provides a stable anchoring of the support foot body on the support surface, where bending forces within the support foot body are properly and efficient transferred to the support surface.
In an embodiment, the support foot body comprises two further support pillars 20 connected by a further bridge element connecting the two further support pillars, wherein a first end of the transverse beam is placed on the bridge element and a second end of the transverse beam is placed on the further bridge element, and wherein the transverse beam is connected to the anchor element between the first end and the second end of the transverse beam.
25 In an embodiment, the two support pillars and the two further support pillars are connected to each other by a bottom construction configured to be placed on the support surface, wherein the bottom construction comprises a central opening through which the anchor element can be anchored with the support surface.
In an embodiment, wherein each of the two support pillars are configured to support a 30 lower end of a solar panel device, and wherein each of the two further support pillars are configured to support an upper end of a solar panel device.
In an embodiment, the anchor element comprises a dome shaped element configured to be connected to the support surface. Such dome shaped elements provide a proper transfer of forces from the transverse beam to the support surface, such as a roof surface in 35 all directions.
In an embodiment, the panel holder comprises at the first end one or more further bottom wall openings in or one or more further bottom wall extensions on the bottom wall of -7- the panel holder configured to be coupled to the first support, and wherein the panel holder comprises at the second opposite end one or more further side wall openings in or one or more further side wall extensions on the side wall of the panel holder configured to be coupled to the second support. By coupling a single support to the solar panel device using in 5 combination one or more side wall openings or extensions of the panel holder and one or more bottom wall openings or extensions of the panel holder, the fixation and support of the solar panel device on the support can be improved.
In an embodiment, at least one of the first support and the second support forms a connection element to connect the solar panel device and a second solar panel device, 10 wherein the connection element comprises at one end at least one side extension to cooperate with the one or more side wall openings in the panel holder of the solar panel device, and wherein the connection element comprises at an opposite side at least one bottom extension to cooperate with the one or more bottom wall openings in the panel holder of the second solar panel device.
15 The connection elements may be used to support one or more solar panel devices on an inclined support surface, for example an inclined roof surface, or to mount one or more solar panel device on a vertical support surface, such as a vertical wall.
In an embodiment, the connection element comprises at the one end at least one further bottom extension to cooperate with the one or more further bottom wall openings in 20 the panel holder of the solar panel device, and wherein the connection element comprises at the opposite side at least one further side extension to cooperate with the one or more further side wall openings in the panel holder of the second solar panel device.
In an embodiment, the connection element comprises a base plate and two side plates extending perpendicularly at opposite sides from the base plate, wherein the two side plates 25 are provided at one end of the connection element with side extensions, and wherein the base plate is provided at the other end of the connection element with at least one bottom extension. In a further embodiment, both ends of the side plates are provided with side extensions and both ends of the base plate are provided with bottom extensions.
The invention further relates to a substantially plate shaped solar panel device having a 30 main plane comprising a solar panel and a panel holder holding the solar panel, the panel holder having a side wall and a bottom wall, and wherein the panel holder comprises at a first end one or more side wall openings in or one or more side wall extensions on the side wall of the panel holder to couple to a first coupling element, and 35 wherein the panel holder comprises at an opposite second end one or more bottom wall openings in or one or more bottom wall extensions on the bottom wall of the panel holder to couple to a second coupling element.

Figure 11 shows a connection element to connect and support two solar panel devices.
Figures 12 and 13 show steps of mounting a solar panel device with the connection 30 element of Figure 11; and
Figures 14 and 15 show the connection between the connection element and the first and second end of a solar panel device in more detail.
35 Figure 1 shows a perspective view of an assembly of four support feet 1 and a solar panel device 2 supported on the four support feet 1. The solar panel device 2 is supported in an inclined position, wherein two support feet 1 support the solar panel device 2 at the low - 10- end and two support feet 1 support the solar panel device 2 at the high end of the solar panel device 2 in the inclined position.
The assembly of Figure 1 is in particular configured to be place on a horizontal or substantially horizontal support surface, such as a flat roof surface.
5 The solar panel device 2 comprises a solar panel 3 and a panel holder 4. The solar panel 3 comprises one or more glass plates and a layer of solar cells laminated to at least one of the glass plates. The solar panel 3 may also comprise any other suitable plate material. The solar cells are configured to generate electrical energy from solar radiation.
The inclined position is selected to increase the amount of solar radiation that is 10 radiated on the solar panel 3 and to keep the solar panel clean.
The solar panel 3 is connected, for example glued to a panel holder 4. The panel holder 4 provides constructive support to the solar panel 3. The panel holder 4 does not enclose the peripheral edge of the solar panel 3. Such embodiment is also referred to as a frameless solar panel device 2.
15 The solar panel 3 may for example be a solar laminate comprising a glass plate and a photovoltaic layer/a layer of photovoltaic cells bonded to the glass plate, or a glass-glass type panel comprising a photovoltaic layer/a layer of photovoltaic cells arranged between two glass plates.
Figure 2 shows a perspective view on the bottom of the solar panel device 2. The 20 panel holder 2 comprises panel holder parts 5 arranged at opposite ends of the solar panel holder 2 and having recesses to receive five beams 6 between the two panel holder parts 5.
In alternative embodiments, more or less beams 6 may be arranged between the panel holder parts 5.
The length and width of the panel holder 4, i.e. in the direction parallel to the main 25 plane of the solar panel 3, is smaller than the length and width of the solar panel 3 it self.
Therefore, the solar panel 3 completely covers the panel holder 4, i.e. the panel holder 4 does not extend from below the solar panel 3 in a direction substantially parallel to the main plane of the solar panel.
The panel holder parts 5 are made of plastics material, or other moldable material, 30 which gives form freedom to create during manufacturing different functions in the panel holder parts 5. The beams 6 are preferably stiff, and may for instance be made of metal, such as steel or aluminum, or reinforced plastics material.
The panel holder parts 5 of the shown embodiment of the panel holder 4 are identical, but may also different dependent on the desired functions of the panel holder parts 5. Also 35 the five beams 6 are, in the shown embodiment, identical. As a result, the panel holder 4 is constructed from two different parts which can easily be assembled by placing the opposite ends of the beams in the respective panel holder parts 5.

The panel holder 4 comprises an upper side 7a on which the solar panel 3 is connected, for instance glued, and a lower side 7b opposite the upper side. The peripheral space connecting the upper side 7a and the lower side 7b is at least partially formed by a side wall 8. The side wall 8 may be formed by a wall or any other construction forming a 5 connection between the upper side 5 and lower side 7b of the panel holder 4. The side wall 8 may for instance also be defined by connecting struts or such, and may extend over only a part of the peripheral edge of the panel holder 4.
The construction and characteristics of the solar panel device 2, or alternative embodiments thereof, are described in more detail in co-pending PCT application having 10 application number PCT/NL2012/050294, the contents of which are herein incorporated by reference.
Figures 3 and 4 show a detailed view of one of the four corner areas of the panel holder 4, formed by the panel holder part 5 in perspective top view on upper side 7a and side wall 8 of the panel holder and bottom view on lower side 7b and side wall 8, respectively.
15 This corner area is formed to function as a lower end coupling element when the corner area is positioned at a lower end of the solar panel device 2 when supported by the support feet 1 in the inclined position, and an upper end coupling element when the corner area is positioned at a lower end of the solar panel device 2 when supported by the support feet 1 in the inclined position.
20 The advantage of the corner areas forming both a lower end coupling element and an upper end coupling element is that the solar panel device 2 can be mounted on the support feet 1 independent of its orientation. It is also possible that the corner areas at a first end of the panel holder 4 only comprise a lower end coupling element, while the corner areas at the opposite end of the panel holder 4 only comprise an upper end coupling element.
25 The lower end coupling element comprises two side wall openings 9 in the side wall 8 of the panel holder 4. The side wall openings 9 can be entered by extensions extending in a direction substantially parallel to the main plane of the solar panel device 2.
The upper end coupling element comprises a bottom wall opening 10 formed in the bottom wall of the panel holder part 5. This bottom wall forms part of the lower side 7b of the 30 panel holder 4. The bottom wall opening 10 can be entered by extensions extending in a direction substantially perpendicular to the main plane of the solar panel device 2.
The corner area further comprises a side wall locking hole 11 extending in a direction substantially parallel to the main plane of the solar panel device 2. The side wall locking hole 11 is configured to receive at least partially a locking pin to lock the upper end coupling 35 element when it is coupled to a support foot 1.
Figure 5 shows a support foot body of the support foot 1 in more detail. The support foot body is made of plastics material and comprises two lower support pillars 12 and two higher - 12- support pillars 13. Each of the lower support pillars 12 is configured to support a lower corner area of a panel holder 4 of a solar panel device 2, when positioned in the inclined position, while each of the higher support pillars 13 is configured to support a higher corner are of a panel holder 4 of a solar panel device 2, when positioned in the inclined position.
5 The two lower support pillars 12 are connected to each other by a bridge element 14 and the higher support pillars 13 are connected to each other by a bridge element 15. The support foot 1 further comprises a bottom plate 16 and two side ribs 17. The two side ribs 17 each connect a lower support pillar 12 and a higher support pillar 13 to each other.
Each lower support pillar 12 comprises a pillar support surface 18 to support a corner 10 area of the solar panel device 2 and two lower support extensions 19 to cooperate with the two side wall openings 9 of the panel holder 4. The two lower support extensions 19 extend in a direction substantially parallel to the main plane of the solar panel device 2, when the solar panel device 2 is mounted on the support feet 1 as shown in Figure 1. By placing the two lower support extensions 19 in the two side wall openings 9 a coupling between the solar 15 panel device 2 and a support foot 1 at the lower end of the solar panel device 2 in the inclined position wherein it is mounted, is obtained.
Each of the lower support pillars 12 further comprises a further extension 20 extending in an upwards direction. This further extension 20 is configured to extend, in the coupled position of the solar panel device 2, into the bottom wall opening 10 of the pane holder 4 to 20 enhance the coupling between the solar panel device 2 and the support foot 1.
The two higher support pillars 13 each comprise a pillar support surface 21 to support the upper end of the solar panel device 2 in the inclined position. The two higher support pillars 13 also each comprise an upper support extension 22 to cooperate with the bottom wall opening 10 of the panel holder 4. The upper support extension 22 extends in a direction 25 substantially perpendicular to the main plane of the solar panel device 2 when mounted in the inclined position on the support feet 1.
Each of the higher support pillars 13 further comprises a locking extension 23 comprises a through-going support locking hole 24. When a solar panel device 2 is mounted on the support feet 1 as shown in Figure 1, the support locking hole 24 will be aligned with the 30 side wall locking hole 11, such that a locking pin can be placed through the support locking hole 24 in the side wall locking hole 11. The presence of such locking pin in the locking hole 24 and the side wall locking hole 11 results in that the upper end of the solar panel device 2 cannot be moved upwards from the support foot 1 in a direction substantially perpendicular to the main plane of the solar panel device 2. As a result, the coupling between the upper 35 support extension 22 and the bottom wall opening 10 is effectively locked.
Figures 6, 7, and 8 show in side subsequent steps in the mounting of a solar panel device 2 on the support feet 1.
- 13-
In a first step, as shown in Figure 6, a first coupling movement is performed in which the solar panel device 2 is moved in a direction substantially parallel to the main plane of the solar panel device 2. In this first coupling movement, the two lower support extensions 19 of the support foot 1 are placed in the side wall openings 9 of the panel holder 4. When this 5 coupling at the lower end of the solar panel device 2 is created, at both support feet 1 for the lower end of the solar panel device 2 (see also Figure 1), a second coupling movement can subsequently be performed.
During the second coupling movement, the solar panel device 2 is coupled at its upper end to each of two higher support pillars 13. This coupling is created by placing the upper 10 support extension 22 of a higher support pillar 13 in the bottom wall opening 10 of the panel holder. In this second coupling movement the upper support extension 22 and the bottom wall opening 10 move in a direction towards each other substantially perpendicular to the main plane of the solar panel device 2.
During the second coupling movement the coupling at the lower end of the solar panel 15 device 2 between the two lower support extensions 19 and the two side wall openings 9 is used as a pivot about which the solar panel device 2 is rotated.
Figure 7 shows the solar panel device 2 during this rotating movement.
As a result of this rotating movement the further extension 20 may be placed in the bottom wall opening 10 at the lower end of the panel holder to further enhance the coupling 20 between the lower end of the solar panel device 2 and the lower support pillar 12.
Due to this two-step movement, the first coupling between the two lower support extensions 19 and the two side wall openings 9, is locked by the second coupling between the upper support extension 22 and the bottom wall opening 10. Thus, the first coupling cannot be released before the second coupling is released. As a result, the complete 25 mounting of the solar panel device 2 on the support feet 1 can be locked by locking the second coupling at the upper end of the solar panel device 2.
This is advantageous as the first coupling is more difficult to reach, in particular in the case of a frameless solar panel device 2, where the panel holder 4 is completely covered by the solar panel 3.
30 Figure 8 shows the step of locking the second coupling. The locking of the second coupling between the upper support extension 22 and the bottom wall opening 10 can be realized by placing a locking pin 25 through the support locking hole 24 of the locking extension 23 in the side wall locking hole 11. By placement of the locking pin 25 undesirable premature release of the second coupling and therewith the first coupling is prevented. Any 35 other suitable locking device for, in particular, locking the second coupling between the upper support extension 22 and the bottom wall opening 10 may also be provided.

It is remarked that in the mounted position, as shown in Figure 1, the solar panel device 2 may be supported by the pillar support surfaces 18, 21, the two lower support extensions 19, the upper support extension 22 and/or the further extension 20 or any other suitable part of the support feet 1.
5 Further, it is remarked that the dimensions of the lower support extensions 19, the upper support extension 22 and the further extension 20 are selected smaller than the associated side wall openings 9 and bottom wall opening 10, such that a certain amount of play is present to compensate for external influences such as for example expansion and contracting due to temperature differences.
10 As shown in Figure 1, each support foot 1 is only used to support one corner area of the solar panel device 2 on one of the lower support pillars 12 or higher support pillars 13. However, each of the support feet 1 comprises three further pillars to support further corner areas of a solar panel device 2.
Figure 9 shows an assembly of six solar panel devices 2, mounted on twelve support 15 feet 1. The support feet at the periphery of the assembly may be selected for mounting further solar panel devices 2. It is also possible that one or more support feet at the periphery of the assembly are configured (not shown) to support only one or two corner areas of solar panel devices 2.
Figure 10 shows a perspective view of one of the support feet 1. In this view it can be 20 seen that the bottom plate 16 comprises a central opening 26 and a plurality of drainage openings 27. The central opening 26 is provided to make placement of anchoring device 28 in the middle of the two lower support pillars 12 and the higher support pillars 13 possible.
The anchoring device 28 comprises an anchor element 29 to anchor the anchoring device 28 to the support surface, such as a roof surface. The anchor element 29 is a dome 25 shaped element configured to be connected to the support surface, such as a roof surface. The anchor element may also comprise a flat shaped, for example plate shaped element configured to be connected to the support surface. Such a flat or dome shaped element has the advantage that forces exerted on the anchor element 29 can properly be transferred in any direction to the support surface. Any other suitable anchoring device to anchor the 30 support foot to the support surface may also be applied.
At the top of the anchor element 29 a transverse beam 30 is connected by a bolt 31. A first end of the transverse beam 30 is placed on the bridge element 14 between the two lower support pillars 12 and the other opposite end of the transverse beam 30 is placed on the bridge element 15 between the two higher support pillars 13. The transverse beam 30 is 35 made of relatively stiff material compared to the plastics material of the support foot body.
The transverse beam 30 is for example made of metal. The presence of the transverse beam takes away the need to provide a large amount of plastics material between the lower support - 15- pillars 12 and the higher support pillars 13 to resist high bending forces caused by transfer of forces from the top of the lower and higher support pillars 12, 13 to the anchor element 29. As a result, the bottom plate 16 and the two side ribs 17 and feet 1 as a whole can have a relative low volume. Therefore the support foot 1 requires less plastics material and makes it 5 less costly.
The ends of the transverse beam are advantageously place on the bridge elements 14, 15 between the two lower support pillars 12 and higher support pillars 13 so that bending forces that are often similar on the two lower support pillars 12 or the two higher support pillars 13 are compensated by each other.
10 In Figure 9 each support foot 1 is anchored to the support surface by its own anchoring device 28. In other embodiments, some anchoring devices 28 may be omitted. Any other type of anchoring device may also be applied.
Figures 11-15 show another embodiment of an assembly according to the invention comprising one or more solar panel devices 2 and at least one connection element 50 to 15 connect a first solar panel device 2 with a second solar panel device 2’. The assembly of one or more solar panel devices 2 and a number of connection elements 50 connecting the one or more solar panel devices 2 to each other is configured to be placed on an inclined surface, such as an inclined roof surface or beam structures as utilized in for example car park overhead constructions. Since the solar panel devices 2 are mounted on an inclined surface 20 the connection elements 50 do not have to create a height difference between a lower and higher end of a mounted solar panel device 2. The connection elements 50 may also be used to mount one or more solar panel devices 2 on a vertical surface, such as a vertical wall.
The connection elements 50 are configured to connect two corner areas of two solar panel devices 2 to each other, and to support the solar panel devices 2 when mounted on a 25 support surface 70.
The connection element 50 is shown separately in Figure 11. The connection element 50 comprises a base plate 51 and two side plates 52 extending perpendicularly at opposite sides of the base plate 51 from the base plate 51. The side plates 52 each comprise at one end first side plate extensions 53, and at an opposite end second side plate extensions 54.
30 The first side plate extensions 53 and the second side plate extensions 54 are configured to be placed in a side wall openings 9 of a respective solar panel device 2 to couple a solar panel device 2 to the connection element 50 at either end of the connection element 50.
The base plate 51 comprises at the one end a bottom extension 55 extending from the 35 upper surface of the base plate 51. This bottom extension 55 is configured to cooperate with a bottom wall opening 10 of a solar panel device 2.
- 16-
Similarly, the base plate 51 comprises at the opposite end two base plate rim elements 56 (only one visible in Figure 11) extending upwards from the upper surface of the base plate, 1. e. in the direction of the side plates 52. These base plate rim elements 56 are configured to enter a bottom groove 10’ formed by a bottom wall opening in the bottom wall of the panel 5 holder 4.
Further, the base plate 51 comprises holes 57 to receive fixation devices such as screws or bolts to fix the connection element 50 to the underlying surface.
The connection element 50 can for example be formed from cutting and bending a metal plate, but also from any other suitable material and in any other suitable way.
10 In the shown embodiment, the first side plate extensions 53 and the second side plate extensions 54 are formed by bending a part 58 of the side plates 52 in a direction parallel to the base plate 51 resulting in a spacing between the base plate 51 and the first and second side plate extensions 53, 54 with a height corresponding to the distance between the side wall openings 9 and the bottom wall of the panel holder 4.
15 A solar panel device 2 can be mounted to an underlying support surface 70 by mounting connection elements 50 at each of the corners of a solar panel device 1.
It is remarked that the connection element 50 shown in Figure 11 comprises first side plate extensions 53 at one end and second side plate extensions 54 at another end. This makes the connection element 50 suitable to be connected to two adjacent solar panel 20 devices 2 mounted arranged on a support surface. In case only at one side of the connection element a solar panel device 2 should be connected, the connection element 50 may be provided with only first side plate extensions 53 and a bottom extension 55, or, alternatively with only second side plate extensions 54 and base plate rim elements 56.
The following method can be used to mount a number of solar panel devices 2 on an 25 inclined or vertical surface in a simple and reliable manner. In a first step, as shown in Figure 12, two lower connection elements 50 are mounted on the support surface 70. The lower connection elements 50 may be connected with further solar panel devices 2’, which are previously arranged on the support surface 70, as shown in Figure 12. When the connection elements 50 are fixed to the support surface 70, the solar panel device 2 may be arranged 30 with its side wall openings 9 on the first side plate extensions 53 with a movement substantially parallel to the main plane of the solar panel device 2, as indicated by arrow M1.
When the first side plate extensions 53 are arranged in the side wall openings 9, two further connection elements 50 may be connected to the other side of the solar panel device 2. First, the base plate rim elements 56 are placed in the bottom groove 10’ of the panel 35 holder 4, as shown in Figure 13.
As a next step, the connection elements 50 can be rotated with respect to the solar panel device 2, as a consequence of which the second side plate extensions 54 will move - 17- into the side wall openings 9 of the solar panel device 2.This movement of the connection elements 50 is indicated by an arrow M2. After this movement, the connection elements 50 are mounted to the solar panel device 2.
Thereafter, by movement of the respective end of the solar panel device 2 in a direction 5 substantially perpendicular to the main plane of the solar panel device, indicated by arrow M3, the solar panel device 2 can be moved towards the support surface 70. It is remarked that the connection between the first side plate extensions 53 and the side wall openings 9 form a rotating axis for this movement in direction of arrow M3, similar to the mounting method on the supports 1, as shown in Figures 6, 7 and 8.
10 At the end of this movement in direction M3, the solar panel device 2 will extend parallel to the support surface 9. In this final mounting position, the upper end of the solar panel device 2 will be held, as shown for solar panel device 2’ in Figure 12, between the second side wall extensions 54 and the base plate rim elements 56 placed in the side wall openings 9 and the bottom groove 10’, respectively.
15 Furthermore, during the movement of the solar panel device 2 in the direction of arrow M3, the bottom extension 55 of the connection element 50 at the lower end of the solar panel device 2 moves into the bottom wall opening 10 of the solar panel device 2. As a result, the lower end of the solar panel device 2 will be held between the first side wall extensions 53 and the bottom extension 55 placed in the side wall openings 9 and the bottom wall opening 20 10, respectively.
When, the connection element 50 is subsequently fixed to the support surface 70, the solar panel device 2 is securely fixed to the support surface 70, where it is supported by the connection elements 50.
In an alternative mounting method, the connection element 50 is not rotated in the 25 direction M2, after the first movement indicated by arrow M1 in Figure 12, but the solar panel device 2 is directly moved towards the support surface 70 by movement in the direction indicated by arrow M3. During this rotating movement in direction M3, the connection elements 50 will also be rotated with respect to the solar panel device 2 in direction M2, since the connection element 50 is pressed at the side of bottom extension 55 against the support 30 surface 70. As a consequence of this rotating movement of the connection elements 50, the second side plate extensions 54 will move into the side wall openings 9 of the solar panel device 2.
The above mounting methods makes quick and efficient mounting of a solar panel device 2 on an inclined support surface, for example an inclined roof surface, possible.
35 Figure 14 shows the final connection between one end of the connection element 50 and the solar panel device 2 in more detail, while Figure 15 shows the final connection - 18- between the opposite side of the connection element 50 and the solar panel device 2 in more detail.
When desired further solar panel devices 2 may be mounted on the support surface 70 by repeating the above described steps for a next solar panel device 2. In this way, the 5 inclined support surface 70 can be covered by a matrix of solar panel devices 2. However, with the embodiment of the connection element 50 of Figure 11 each connection element 50 connects and supports two solar panel devices 2, while the supports 1 supports four solar panel devices 2. In alternative embodiments, the connection elements 50 may be configured to connect and support more than two solar panel devices 2, for example four, and the 10 supports 1 may be configured to support two solar panel devices 2.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
