Although the assembly of the solar power plant from separate elements which are mounted onto the outside of the shipping container according to the present invention is more labor intensive than using a pivoting or sliding mechanism as disclosed in US2008/0196758, the building kit of the present invention can use a standard shipping container and there is no need for making expensive adjustments to a standard shipping container .
In an embodiment, the solar panels are separate from the container when moved from the transportation state to the assembled state. Preferably, in the transportation state, the solar panels are arranged inside the container as packaged by the solar panel supplier. During the assembly the solar panels are taken out of the container and subsequently mounted onto the support frame.
In an embodiment, the shipping container comprises attachment members, wherein the one or more connecting members are connectable to the attachment members of the shipping container. Preferably, the attachment members comprise corner castings. Accordingly, the building kit of the present invention preferably uses the corner castings of a standard shipping container and there is no need for making expensive adjustments to a standard shipping container.
In an embodiment, the building kit comprises fasteners for connecting the one or more connecting members to the attachment members of the shipping container. Preferably, the fasteners are twist lock fasteners. In particular the twist lock fasteners which are arranged to cooperate with the corner castings of a standard shipping container are highly preferable, since they provide an easy and quick mounting of the connecting members to the outside of the shipping container.
In a first embodiment, the one or more connecting members comprise a strut having a first end and a second end opposite to the first end, wherein the first end of the strut is mountable to the outside of the shipping container and the second end of the strut is connectible to a point at the sideways projecting support frame at a distance from the shipping container. In an embodiment, the first end of the strut is mountable to the outside of the shipping container at a position within 1 meter above the bottom of the shipping container. Preferably, the strut is mountable to the outside of the shipping container at one of the corner castings at the bottom of the shipping container. The strut provides a suitable support at least for the part of the support frame which extends in a sideways direction away from the shipping container. Accordingly, there is no need to provide support legs which rest on the underground surrounding the shipping container.
In a second embodiment, the one or more connecting members comprise a strut, having a first end and a second end opposite to the first end, and a girder having a first end and a second end opposite to the first end, wherein the first end of the girder is mountable to the shipping container and the second end of the girder is connectible to a point at the sideways projecting support frame at a distance from the shipping container, and wherein the first end of the strut is mountable to the shipping container and the second end of the strut is connectible to a point at the girder at a distance from the shipping container. In an embodiment, the first end of the girder is mountable onto the outside of the shipping container at a position within 1 meter below the top of the shipping container, and wherein the first end of the strut is mountable onto the outside of the shipping container at a position within 1 meter above the bottom of the shipping container. Preferably, the first end of the girder is mountable to a first one of the corner castings at the top of the shipping container, and wherein the first end of the strut is mountable to a first one of the corner castings at the bottom of the shipping container, preferably positioned right below the first one of the corner castings at the top of the shipping container. As indicated above, the strut provides a suitable support at least for the part of the support frame which extends in a sideways direction away from the shipping container. In addition, the combination of the strut with the girder allows to mount the strut in its final supporting position, before the support frame is mounted onto the girder and strut. Accordingly, the solar power plant is more easily put together when using the building kit according to this embodiment.
In an embodiment, the girder and strut are hingedly attached to each other. Preferably, the girder and the strut are provided preassembled in the transportation state. By providing the girder and strut in a preassembled state, the solar power plant is more easily put together.
In an embodiment, at the girder and the strut are beams with nesting profiles. The girder and the strut can be arranged in a nested position inside the shipping container during the transportation state. Accordingly the parts for building the solar power plant can be arranged more compact inside the shipping container in the transportation state.
In a third embodiment, the one or more connecting members comprise a carrier, a strut having a first end and a second end opposite to the first end, and a girder having a first end and a second end opposite to the first end, wherein the carrier is mountable to the shipping container along a side of the shipping container, wherein the first end of the girder is mountable to the carrier and the second end of the girder is connectible to a point at the sideways projecting support frame at a distance from the shipping container, and wherein the first end of the strut is mountable to the carrier and the second end of the strut is connectible to a point at the girder at a distance from the shipping container. In an embodiment, the carrier is mountable to two of the corner castings, situated one above the other, wherein the first end of the girder is mountable to the carrier at a position within 1 meter below the upper one of the two corner castings, and wherein the first end of the strut is mountable to the carrier at a position within 1 meter above the lower one of the two corner castings. As indicated above, the strut provides a suitable support at least for the part of the support frame which extends in a sideways direction away from the shipping container. In addition, the strut, the girder and the carrier can be pre-mounted together before mounting onto the outside of the shipping container. The pre-mounted carrier with strut and girder can be mounted as one unit to the outside of the shipping container, before the support frame is mounted onto the girder and strut. Accordingly, the solar power plant is more easily put together when using the building kit according to this embodiment.
In an embodiment, the one or more connecting members comprise one or more hinges for hingedly connecting at least one of the girder and the strut to the carrier. Preferably, the girder and/or the strut, when hingedly connectable to the carrier, are provided preassembled to the carrier in the transportation state. By providing the girder and/or strut in a preassembled state, the solar power plant is more easily put together.
In an embodiment, at least the carrier and the girder, or the carrier and the strut are beams with nesting profiles. The carrier, with the girder and/or the strut can be arranged in a nested position inside the shipping container during the transportation state. Accordingly the parts for building the solar power plant can be arranged more compact inside the shipping container in the transportation state.
In an embodiment, the frame is arranged to extend substantially across the shipping container and further in a sideways direction away from the shipping container. This embodiment allows, inter alia, to optimally use the available space above and adjacent to the container for mounting solar panels. In an embodiment, the frame is arranged substantially centrally above the container. This provides a suitable weight distribution on the container, which enhances the stability of the solar power plant under various weather and/or wind conditions.
In an embodiment, the support frame comprises guide members, adapted for slidingly receiving the plurality of solar panels in a sliding direction along the support plane. Accordingly, the solar panels can be easily arranged on the support frame by sliding the solar panels onto a desired location on said frame. Preferably the guide members are arranged for sliding multiple solar panels, one after the other, in the sliding direction onto the support plane. A solar panel which has been slided onto the support plane, for example from a side edge of the support frame, can be pushed further along the support plane by a subsequent solar panel which is slided onto the support plane. This allows to position solar panels on the support frame further away from the side edge of the support frame without having to reach over the support frame.
In an embodiment, the guide members comprise a support surface and a guide surface perpendicular to the support surface, wherein the support surface, in the assembled state, lies in the support plane and extends in the sliding direction for supporting one or more solar panels of the plurality solar panels, and wherein guide surface, in the assembled state, extends in the sliding direction for retaining the one or more solar panels in a direction transverse to the sliding direction along the support plane. Preferably the guide surface is arranged to guide an edge of a solar panel in de sliding direction, preferably said edge of the solar panel is a longitudinal edge of the solar panel.
In an embodiment of the building kit for a solar power plant in the assembled state, two of the guide members are mounted along the support plane in a mutually parallel orientation to form a slot for slidingly receiving the one or more solar panels and for retaining the solar panels in the direction of the support plane and along the support plane in a direction transverse to the sliding direction. Accordingly, the present embodiment allows to easily slide that the solar panels between the two guide members, in a substantially linear sliding direction parallel to the future early parallel orientated guide members. The parallel guide members are arranged to guide a solar panel on to opposite sides, preferably to longitudinal opposite sides of the solar panel.
In an embodiment, the guide members further comprise a retaining member, wherein the retaining member is arranged spaced apart from the support plane in a direction substantially perpendicular to the support plane for retaining the one or more solar panels in a direction transverse to the support plane. The retaining member provides a confinement of the solar panels substantially in the support plane and substantially prevents that the solar panels move out of the support plane in a direction substantially perpendicular to the support plane, which may for example be caused by wind blowing underneath the solar panels arranged on the support frame.
In an embodiment, the retaining member comprises a retaining surface, wherein the retaining surface, in the assembled state, extends parallel to the support plane at a distance of the support plane, in the sliding direction. In an embodiment, two of the guide members are mountable along the support plane in a mutually parallel orientation to form, in the assembled state, a slot for slidingly receiving the one or more solar panels and for retaining the solar panels in the direction of the support plane, the direction transverse to the support plane and along the support plane in a direction transverse to the sliding direction. These embodiments allow to spread a retaining force for keeping the solar panels substantially in the support plane over a larger area, which substantially prevents damage to the solar panels when they are lifted up, for example, by wind blowing underneath the solar panels arranged on the support frame.
In an embodiment, the support frame comprises longitudinal beams and transverse beams, wherein, in the assembled state, at least two the longitudinal beams are mounted onto the shipping container by means of the one or more connecting members and wherein the transverse beams are mounted onto the longitudinal beams in a direction transverse to the longitudinal beams. It is noted that a shipping container usually has a substantially rectangular top surface wherein two opposite side edges are longer that the other two opposite side edges. The longer two side edges define a longitudinal direction of the shipping container, whereas the shorter two side edges define the transverse direction of the shipping container. In the assembled state, the longitudinal beams of the support frame extend in a direction substantially parallel to the longitudinal direction of the shipping container. Since the support frame is build up from substantially individual longitudinal and transverse beams, the support frame in the assembled state can be much larger than the upper surface of the shipping container, in addition to be able to store the longitudinal beams and the transverse beams separate from each other inside the shipping container in the transportation state.
In an embodiment, the transverse beams comprise the guide members. Preferably the transverse beams and the guide members are formed as a unity. Accordingly, it is not necessary to perform a separate mounting of the guide members, which makes it easier and quicker to build the support frame according to this embodiment.
Although the support frame can be made from a polymer of composite material, in an embodiment, the support frame and the one or more connecting members are made of metal, preferably aluminum.
In an embodiment, the shipping container forms a foundation for the solar power plant in the assembled state. In an embodiment, the shipping container supports a substantial part of the weight of the power plant, preferably at least 80 percent, more preferably at least 90 percent, most preferably at least 100 percent. According to this preferred embodiment, the container is not only used for transport of the building kit in the transportation state, but is also part of the solar power plant in the assembled state.
In an embodiment, the support plane is projecting away from the shipping container in an outwards descending direction. Accordingly, the descending direction allows precipitation, such as rain or snow, to slide off the solar panels which are mounted on the descending support plane.
In an embodiment, the shipping container comprises one or more batteries for storing at least a part of the generated energy, wherein the batteries are preferably fixed in the shipping container. Accordingly, any surplus of generated electricity by the solar power plant can be stored for use in times where the generation of electricity is interrupted, for example when the sun is blocked by clouds or for example at night. In addition or alternatively, the electricity stored in the batteries can also be used when there is a high demand of electricity, or when the demand of electricity is higher than the generated electricity by the solar panels of the solar power plant.
According to a second aspect, the invention provides a solar power plant comprising a shipping container, a plurality of solar panels, a support frame for supporting the plurality of solar panels and one or more connecting members for connecting the support frame to the shipping container, wherein the support frame is mounted onto the outside of the shipping container by means of the one or more connection members, wherein the plurality of solar panels is mounted onto the support frame, wherein the support frame, with the plurality of solar panels mounted thereon, is arranged to extend substantially across the shipping container and further in a sideways direction away from the shipping container.
In an embodiment, the shipping container comprises attachment members, and the one or more connecting members are connected to the attachment members. In an embodiment, the attachment members are corner castings .
According to a third aspect, the invention provides a method for assembling a solar power plant using the building kit or an embodiment thereof as described above, wherein the method comprises the steps of: a) placing the shipping container in a substantially horizontal position on an underground; b) mounting the support frame onto the shipping container by means of the one or more connecting members; c) mounting the plurality of solar panels onto the support frame; wherein the support frame and the connecting members are separate from the container when moved from the transportation state to the assembled state.
In an embodiment, the solar panels are separate from the container when moved from the transportation state to the assembled state.
In an embodiment, the mounting of the plurality of solar panels in step c) comprises the step of sliding the solar panels onto the support frame, preferably from a side of the support frame which faces away from the shipping container.
The various aspects and features described and shown in the specification can be applied, individually, wherever possible. These individual aspects, in particular the aspects and features described in the attached dependent claims, can be made subject of divisional patent applications .

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows an example of a solar power plant 2 according to the present invention in an assembled state, which solar power plant is assembled from a building kit 1, which will be described in more detail below with reference to figure 2.
As shown in figure 1, the solar plant 2 comprises a shipping container 3, a plurality of solar panels 4, a support frame 8 for supporting the plurality of solar panels 4. The support frame 8 defines a support plane for the solar panels 4, which support plane projects away from the shipping container 3 in a sideways direction. The solar power plant 2 comprises one or more connecting members 5 for connecting the support frame 8 to the shipping container 3. The one or more connecting members 5 are mounted onto the outside of the shipping container 3 and the support frame 8 is mounted onto the outside of the shipping container 3 by means of the connecting members 5. The plurality of solar panels 4 is mounted onto the support frame 8, wherein the support frame 8, with the plurality of solar panels 4 mounted thereon, projects away from the shipping container 3 in a sideways extending direction. It is observed that in the example shown in figure 1, the support frame 8 extend away from the shipping container 3 in a direction substantially perpendicular to a longitudinal direction L of the shipping container 3, but also in a direction substantially perpendicular to a transverse direction T of the shipping container 3.
As can be seen in figure 1, the shipping container 3 forms a base or foundation of the solar power plant 2. The shipping container 3 supports a substantial part of the weight of the connecting members 5, the support frame 8, and the solar panels 4. In the embodiment shown, the shipping container 3 supports substantially 100 percent of the weight of the connecting members 5, the support frame 8, and the solar panels 4.
Figure 2 shows an example of a building kit 1, which building kit can be assembled to form a solar power plant 2 as for example the one shown in figure 1. The building kit 1 comprises a shipping container 3 in the shape of a substantially rectangular block having longitudinal sides which extend substantially parallel to a longitudinal direction L, and transverse side which extend substantially parallel to a transverse direction T. At the corners of the block shaped shipping container 3, corner castings 31 are arranged, which corner castings 31 are usually used for hoisting the shipping container 3 or for fixing the shipping container 3 onto a carrier, such as a train carriage or a trailer. In this example, the corner castings 31 are also used as attachment members for mounting the connecting members 5 to the outside of shipping container 3 as will be explained in more detail below.
As shown in figure 2, one of the transverse sides comprises two doors 32, which in figure 2 are open to show partially the interior of the shipping container 3. In the transportation state, the solar panels 41 are arranged inside the shipping container 3, preferably the solar panels 41 are arranged inside the container as packaged by the solar panel supplier. In addition, parts 42 for building the support frame and the one or more connection members are provided within the shipping container.
When the building kit 1 has been moved to the desired site for building the solar power plant, the shipping container 3 is placed in a substantially horizontal position on an underground.
In a next step of the process for building the solar power plant, the parts 42 for building the support frame and the one or more connection members are taken out of the shipping container 3. The connecting members 5 are subsequently mounted onto the outside of the shipping container 3. Each connecting member 5 of this example, comprises a strut 50, a girder 60 and a carrier 70, forming a truss construction for supporting the support frame.
As schematically shown in figure 3A, the carrier 70 is mounted to the outside of the shipping container 3 at a longitudinal side LS of the shipping container 3. The carrier 70 has an upper end 71 and a lower end 72 which are provided with fasteners for connecting the carrier 70 to the corner castings 31 of the shipping container. In particular, the carrier 70 is mounted to two of the corner castings 31 of the shipping container 3, situated substantially vertical one above the other. Preferably, the fasteners are twist lock fasteners as for example shown in figure 4 and described in more detail below.
The girder 60 has a first end 61 and a second end 62 opposite to the first end 61. In the assembled state, the first end 61 of the girder 60 is mounted to the carrier 70, in particular near the upper end 71 of the carrier 70.
The strut 50 has a first end 51 and a second end 52 opposite to the first end 51. In the assembled state, the first end 51 of the strut is mounted to the carrier 70, in particular near the lower end 72 of the carrier 70.
The second end 62 of the girder is connected to the second end 52 of the strut at a point spaced apart from the container 3, to form connecting member 5. In this exemplary embodiment the connecting members 5 are extending away from the shipping container 3 in a sideways direction substantially transverse to the longitudinal side LS of the shipping container 3. In particular, the carrier 70, girder 60 and strut 50 are arranged in a plane which is arranged substantially perpendicular to the longitudinal side LS of the shipping container 3.
Subsequently, the parts 42 for building the support frame are assembled. First, a series of longitudinal beams 81 are assembled from longitudinal beam parts 81A, 81B, 81C. Preferably the longitudinal beam parts 81A, 81B, 81C have a length smaller than the inner length of the shipping container 3, so that the longitudinal beam parts can be stored inside the shipping container 3, at least in the transportation state. After assembly, the longitudinal beams 81 are mounted onto the girders 60 of the connecting members 5, as schematically shown in figure 3B. The longitudinal beams 81 that are mounted onto the girders 60 of the connecting members 5, are preferably connected to the girder by means of riveting or welding, more preferably by means of bolting.
In addition, a central longitudinal beam 82 is assembled from central longitudinal beam parts 82A, 82B, 82C. Again, the central longitudinal beam parts 82A, 82B, 82C preferably have a length smaller than the inner length of the shipping container 3, so that the central longitudinal beam parts can be stored inside the shipping container 3, at least in the transportation state. After assembly, the central longitudinal beam 82 is mounted onto the top of the shipping container 3, as schematically shown in figure 3B. The central longitudinal beam 82 is supported by the top of the shipping container 3.
In the present example as shown in figure 3C, the support frame also comprises transverse beams 83. The transverse beams 83, at least in the assembled state, are connected to at least one the longitudinal beams 81 and the central longitudinal beam 82. The transverse beams 83 are mounted onto the longitudinal beams 81, 82 in a direction transverse to the longitudinal beams 81, 82. The transverse beams 83 are preferably connected to the longitudinal beams 81, 82 by means of bolting.
The longitudinal beams 81, 82 and the transverse beams 83 provide a support frame for supporting the plurality of solar panels. Since the support frame is build up from substantially individual longitudinal and transverse beams, the support frame in the assembled state can be much larger than the upper surface of the shipping container, in addition to be able to store the longitudinal beams and the transverse beams separate from each other inside the shipping container in the transportation state. The longitudinal beams 81, 82, and the transverse beams 83 are preferably made of a metal, more preferably made of aluminum. The support frame, in particular the longitudinal beams 81, 82 and the transverse beams 83, and the one or more connection members 5 are separate from the shipping container 3 when moved from the transportation state to the assembled state.
As schematically shown in figure 3C, the support frame extends in a sideways direction away from the shipping container, both in a direction parallel to the transverse direction T of the shipping container 3, as well as in a direction parallel to the longitudinal direction L of the shipping container 3. In addition, the support frame is arranged to extend across the shipping container 3 and further in a sideways direction away from the shipping container 3. In the example shown in figure 3C, the frame is arranged substantially centrally above the shipping container 3.
On both sides of the central longitudinal beam 82, the transverse beams 83 are arranged to project in a direction substantially perpendicular to the central longitudinal beam 82 and in outwards descending direction. Accordingly, the support frame projects away from the shipping container 3 in two outwards descending directions transverse to the longitudinal direction L of the shipping container 3, forming two support planes 80, 80' for supporting the plurality of solar panels 4.
Furthermore, the transverse beams 83 are provided with guide members which are adapted for slidingly receiving the plurality of solar panels 4. Preferably the transverse beams 83 and the guide members are formed as a unity as for example shown in figure 5 and described in more detail below. The solar panels 4 are taken out of the shipping container 3 and subsequently mounted onto the support frame. Accordingly, at least the solar panels 4 are separate from the shipping container 3 when moved from the transportation state to the assembled state.
The guide members are arranged for slidingly receiving the plurality of solar panels 4 in a sliding direction along the transverse beams 83. The guide members preferably extend along substantially the whole length of the transverse beams 83, which enables to slide multiple solar panels 4, one after the other, in the sliding direction onto the support plane. A solar panel 41, 42 which has been slided onto the support plane, for example from a side edge 84, 84' of the support frame, can be pushed further along the support plane by a subsequent solar panel 43 which is pushed P onto the support plane. This allows to position solar panels 4 on the support frame further away from the side edges 84, 84' of the support frame without having to reach over the support frame. As schematically shown in figure 3D, the solar panels 4 can be easily arranged on the support frame by sliding the solar panels 4 onto a desired location on said frame.
When all solar panels 4 are arranged onto the support frame and are electrically connected to a control unit and/or an inverter, the solar power plant 2 is ready for use.
Figure 4 shows a detail of the connection between carrier 70 of one of the connecting members according to figure 3A and one of the corner castings 31 in a preferred exemplary embodiment of the solar power plant. The corner castings 31 of the example shown in figure 4, are provided with an openings 32 which are arranged in a side planes of the corner casting 31 which are facing away from the shipping container 3. The openings 32 have an elongated or oval shape and allow access to an interior space of the corner castings 31.
The carrier 70 of the example shown in figure 4 comprises so called twist-lock fasteners 73, for connecting the carrier 70 of the connecting members to the corner castings 31 of the shipping container 3. In figure 4 only one such twist-lock fastener 73 is shown at the upper part of the carrier 70. However, the carrier 70 may also comprise a second twist-lock fastener at the lower end of the carrier 70 in order to connect the carrier 70 to a further corner casting of the shipping container 3, which further corner casting is preferably arranged at the bottom side of the shipping container 3, below the corner casting at the upper side of the shipping container 3.
The twist-lock fastener 73 comprises an elongated or oval end part 74 which can be inserted through an opening 32 of the corner casting, and said end part 74 can be rotated over approximately 90 degrees as schematically shown in figure 4, so that the end part 74 cannot be withdrawn out of the opening 32. Preferably the twist-lock fastener 73 is further provided with a screw tightening mechanism to push or pull the carrier 70 towards the corner casting 31 against the shipping container 3.
Figure 5 shows a detail of the transverse beams 83 with guide members. The transverse beams 83 with guide members are arranged in a mutually parallel orientation, extending in a sliding direction S along the support plane. The guide members comprises a longitudinal slot 85 which extends in the sliding direction S, which slot 85 is arranged to place an edge 42 of a solar panel therein. As schematically shown, the transverse beams 83 with the guide members are arranged to provide a slot 85 at opposite sides of an accommodation space 86 for solar panels 4 between two adjacent transverse beams 83. The solar panels 4, 41 can be slided from the edge 84 of the support frame in the slots 85 in the sliding direction S, to position the solar panels 4, 41 in the accommodation space 86.
The transverse beams 83 and/or the guide members further comprise a locking mechanism for retaining the one or more solar panels 4, 41 at the accommodation space 86. In the example shown in figure 5, the guide members are provided with holes 87 near the edge 84 of the support frame, which holes 87 allow the positioning of a pin 88, in particular a split pin, which prevents that the solar panels 4, 41 slide in the sliding direction S out of the accommodation space 86.
Figures 6A, 6B and 6C show various examples of guide members and/or transverse beams, for use in the building kit and solar power plant of the present invention.
Figure 6A shows a first example where the guide member and the transverse beam are formed as a unit 831. The unit comprises support surfaces 832 for supporting one or more solar panels 4 of the plurality of solar panels 4 and guide surfaces 833 perpendicular to the support surface 832 for retaining the one or more solar panels 4 in a direction transverse to the sliding direction S. In the example of figure 6A, the unit further comprise retaining surfaces 834 for retaining the one or more solar panels 4 in a direction transverse to the support plane. As can further be seen in figure 6 A, each support surface 832, guide surface 833 and retaining surface 834 define a slot 851, 851' for receiving an edge 42 of a solar panel 4.
Furthermore, the unit 831 is provided with holes 871 near an edge of the unit 831. The holes 871 provide a means for positioning a pin (not shown), which pin can be arranged to traverse the slot 851, 851' to form a locking mechanism for preventing the one or more solar panels to slide out of the support surface of the solar power plant.
Figure 6B shows a second example, where the guide member and the transverse beam are formed by two interconnected strips 831a, 831b which are attached to each other to form the transverse beam with guide member 831' . Each of the strips 831a, 831b comprises a so called top- hat-profile. The lower strip 831b provides the support surfaces 832' and part of the guide surfaces 833' . The upper strip 831b provides the retaining surfaces 834' and part of the guide surfaces 833' . When the two strips 831a, 831b are attached to each other, each support surface 832', guide surface 833' and retaining surface 834' define a slot 851, 851' for receiving an edge 42 of a solar panel 4.
Furthermore, the two strips 831a, 831b is provided with holes 871' near an edge of the strips 831a, 831b. The holes 871' provide a means for positioning a pin (not shown), which pin can be arranged to traverse the slot 851, 851' to form a locking mechanism for preventing the one or more solar panels to slide out of the support surface of the solar power plant.
Figure 6C shows a third example comprising a separate transverse beam 831d, and a guide member 831c. The guide member 831c comprises a so called top-hat-profile which is attached to an upper side of the transverse beam 831d. In this example, the upper side of the transverse beam 831d provides the support surfaces 832", whereas the guide member 831c provides the guide surfaces 833" and the retaining surfaces 834". When the guide member 831c is attached to the transverse beam 831d, each support surface 832", guide surface 833" and retaining surface 834" define a slot 851, 851' for receiving an edge 42 of a solar panel 4. Furthermore, the upper surface of the transvers beam 831d and the guide member 831c are provided with holes 871" near an edge of the transvers beam 831d and the guide member 831c. The holes 871" provide a means for positioning a pin (not shown) , which pin can be arranged to traverse the slot 851, 851' to form a locking mechanism for preventing the one or more solar panels to slide out of the support surface of the solar power plant.
Figure 7A shows an exemplary embodiment of one of the connecting members 5 according to figures 1 and 3A. As described above, the connecting member 5 comprises a strut 50, a girder 60 and a carrier 70, forming a truss structure for supporting the support frame 8 and for connecting the support frame 8 to the shipping container 3. In this example, the carrier 70 is mounted to the outside of the shipping container 3 along a side of the shipping container. In particular and as schematically shown in figure 3A, the carrier 7 0 is mounted to two of the corner castings 31 of the shipping container 3, situated one above another .
The girder 60 comprises a first end 61 and a second end 62 opposite to the first end 61, wherein the first end 61 of the girder 60 is mounted to the carrier 7 0 at a first carrier connection point 71. The first carrier connection point 71 is located near the upper end of the carrier 70, preferably within 1 meter below the upper end of the carrier 70, more preferably within 50 centimeter. At the upper end of the carrier 70, a first twist-lock fastener 73 is arranged for connecting the carrier 70 with one of the corner castings 31 at the upper side of a shipping container 3.
The strut 50 comprises a first end 51 and a second end 52 opposite to the first end 51. The first end 51 of the strut 50 is mounted to the carrier 70 at a second carrier connection point 72 below the first carrier connection point 71. The second carrier connection point 72 is located near the lower end of the carrier 70, preferably within 1 meter above the lower end of the carrier 70, more preferably within 50 centimeter. At the lower end of the carrier 70, a second twist-lock fastener 73' is arranged for connecting the carrier 70 with one of the corner castings 31 at a lower side of a shipping container 3.
The second end 62 of the girder 60 is connected to the second end 52 of the strut 50 at a girder connection point 63 spaced apart from the carrier 70. The girder connection point 63 is preferably located near the second end 62 of the girder 60, preferably within 1 meter of the second end 62 of the girder 60, more preferably within 50 cm of the second end 62 of the girder 60.
In order to reduce the amount of work for mounting the connecting members, it is preferred when the girder 60 and/or the strut 50 are hingedly connected to the carrier 70.
In a first example, as shown in figure 7B, the girder 60' is hingedly connected to the carrier 70' at the first carrier connection point 71'. The strut 50' is hingedly connected to the girder 60' at the girder connection point 63'. Accordingly, the carrier 70', the girder 60' and the strut 50' can provided in a partially preassembled state as shown in figure 7B, in the transportation state. During the assembly of the solar power plant, only the first end 51' of the strut 50' needs to be connected to the carrier 70' at a second carrier connection point 72' to obtain the connecting member in the assembled state. In addition, it is advantageous when at least the carrier 70' and the girder 60' and/or the girder 60' and the strut 50' are beams with nesting profiles. Accordingly, the carrier 70' and the girder 60' can be arranged in a partially nested position inside the shipping container in the transportation state. In addition or alternatively, the girder 60' and the strut 50' can be arranged in a partially nested position inside the shipping container in the transportation state. Accordingly the parts for building the solar power plant can be arranged more compact inside the shipping container in the transportation state.
In a second example, as shown in figure 7C, the girder 60" is hingedly connected to the carrier 70" at the first carrier connection point 71". The strut 50" is also hingedly connected to the carrier 7 0", but at the second carrier connection point 72". Accordingly, the carrier 70", the girder 60" and the strut 50" can provided in a partially preassembled state as shown in figure 7C, in the transportation state. During the assembly of the solar power plant, only the second end 52" of the strut 50" needs to be connected to the girder 60" at the girder connection point 63" to obtain the connecting member in the assembled state. In addition, it is advantageous when at least the carrier 70" and the girder 60" and/or the carrier 70" and the strut 50" are beams with nesting profiles. Accordingly, the carrier 70" and the girder 60" can be arranged in a partially nested position inside the shipping container in the transportation state. In addition or alternatively, the carrier 70" and the strut 50" can be arranged in a partially nested position inside the shipping container in the transportation state. Accordingly the parts for building the solar power plant can be arranged more compact inside the shipping container in the transportation state.

The girder 601 comprises a first end 611 and a second end 621 opposite to the first end 611, wherein the first end 611 of the girder 601 is mounted to the shipping container 3 at a first one of the corner castings 31 at the top of the shipping container 3. The second end 621 of the girder 601 is connected to a point at the sideways projecting support frame at a distance from the shipping container 3.
The strut 501 comprises a first end 511 and a second end 521 opposite to the first end 511, wherein the first end 511 of the strut 501 is mounted to the shipping container 3 at a second one of the corner castings 31, right below the first one of the corner castings 31. The second end 521 of the strut 501 is connected to the girder 601 at a girder connection point 631, for supporting the girder 601. The girder connection point 631 is located near the second end 621 of the girder 601, preferably within 1 meter of the second end 621 of the girder 601, more preferably within 50 cm of the second end 621 of the girder 601.
