Description

SOLAR PANEL SUPPORT STRUCTURE, SOLAR CELL PARK & METHOD
TECHNICAL FIELD
The present invention concerns a solar panel support structure that comprises a plurality of posts arranged at a distance from each other, at least one cable that is tensioned between said posts and a fastening element. The present invention also concerns a method for constructing such a solar panel support structure and/or mounting at least one solar panel on said solar panel support structure. The present invention further concerns a solar cell park that comprises at least such a solar panel support structure and at least one solar cell.
BACKGRUND OF THE INVENTION
A solar panel is a collection of solar cells that are interconnected in order to achieve a higher voltage or current. The most common configuration for such interconnections is a framework. A solar cell park often comprises a plurality of support structures that are usually made out of a metal frame, such as an aluminium frame, on which a plurality of solar panels are mounted. Solar panel support structures that are made of a plurality of cables that are tensioned between support elements on which a plurality of solar panels are mounted are however also known.
The published PCT-application no. WO 2012/045129 discloses a solar panel support structure that is made of a cable that is tensioned between a plurality of posts. In order to construct such a solar panel support structure, a cable must be tensioned between the posts and fastened to the posts. Each solar panel must thereafter be mounted on the cable. The fastening elements that are used to mount each solar panel on the cable consists of two parts. A first part is fastened to the back side of a solar panel with adhesive for example. The cable is placed between this first part and a corresponding second part that is connected to the first part, whereby the cable is gripped therebetween.
Constructing such a solar cell park can be a time consuming process.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an improved solar panel support structure that comprises a plurality of posts arranged at a distance from each other, at least one cable (i.e. a cable or a a plurality of cables) that is/are tensioned between said posts and a fastening element, and an improved method for constructing such a solar panel support structure and/or mounting at least one solar panel on such a solar panel support structure.
This object is achieved by a solar panel support structure that includes a fastening element that comprises a hook that is arranged to extend around part of a cable’s periphery, and attachment means, such as a screw or bolt. The fastening element is arranged so that it has the following two functions:
a) to fasten the cable to one of the posts in a way that prevents the cable from moving (horizontally and/or vertically) relative to the post by fastening the cable between the hook and the post by fastening the fastening element to the post using the attachment means, and
b) to clamp at least one solar panel between the cable and a support surface of a clamping component that is fastened to the fastening element using the attachment means so that the solar panel is mounted on the cable via the fastening element.
Such a solar panel support structure is simple and fast to construct and deconstruct, and to mount solar panels on, which leads to savings in both time and costs. Furthermore, because the fastening element can be used for two different purposed, relatively few different components are needed to build a solar panel support structure.
According to an embodiment of the invention the fastening element is arranged to fasten a cable to a gripping element that is integrated into the post, or to a gripping element that is arranged to be fastened to the post. The gripping element is arranged to extend around part of a cable’s periphery whereby the fastening element’s hook and the gripping element together extend around the whole of the cable’s periphery when a cable is fastened between the hook and the gripping element.
According to an embodiment of the invention the hook is arranged to extend around at least 30%, at least 40%, less than 50%, 50%, over 50%, at least 60%, at least 70%, at least 75% or at least 80% of the cable’s periphery and/or the gripping element is arranged to extend around at least 30%, at least 40%, less than 50%, 50%, over 50%, at least 60%, at least 70%, at least 75% or at least 80%of the cable’s periphery. For example, the hook and the gripping element be formed so that they together completely surround the cable when they are mounted on the cable. According to an embodiment of the invention the fastening element comprises a hook opening that is large enough to receive the cable in the hook, whereby the fastening element is arranged to be mountable on the cable directly in its mounting position. This means that the fastening element does not need to be threaded onto the cable at one end of the cable but can be mounted directly in the position it will be fastened to the cable.
According to an embodiment of the invention the fastening element is arranged to clamp a plurality of solar panels between the cable and a support surface of a clamping component that is fastened to the fastening element using the attachment means. An edge of two or four solar panels can be arranged to bear against the cable when the solar panel support structure is in use.
At least one edge of at least one solar panel is for example arranged to bear against said support surface and be clamped between the cable and the support surface when at least one solar panel is mounted on said solar panel support structure.
The word’’clamped” is intended to mean that at least one edge of at least one solar panel is pressed and fixedly held between the cable and the support surface. The cable and the support surface namely constitute parts of a clamping device, which parts are brought together to compress and thereby press and hold at least one edge of at least one solar panel therebetween.
The distance between the cable and the support surface is adjustable since one can select different lengths of the attachment means and how much it shall be turned or pressed in order to achieve a suitable clamping function.
In the solar panel support structure according to the present invention one does consequently not need to take account of a solar panel’s size and/or thickness on mounting the solar panels on a solar panel support structure. The same fastening element can namely be used to mount a plurality of solar panels of different sizes and/or thicknesses. One edge of a solar panel must only be clamped between the cable and a support surface of a clamping component that is fastened to the fastening element using the fastening element’s attachment means so that the solar panel is mounted on the cable via the fastening element. According to an embodiment of the invention the fastening element comprises a plurality of hooks, such as two, three, four or more hooks, that is arranged to extend around part of a cable’s periphery in the same direction or in different directions. The hooks do not necessarily have to be the same size, i.e. a fastening element can contain a plurality of hooks of different size that is arranged to receive a plurality of cables of different sizes.
According to an embodiment of the invention the fastening element comprises two hooks that are arranged to extend around part of a cable’s periphery either in the same direction or in opposite directions so that the hooks’ hook openings are located either om the same side or on opposite sides of the cable when the fastening element is used to fasten a cable to a post.
According to an embodiment of the invention the solar panel support structure comprises an electrically insulating material in at least one of the following locations: between the cable and the hook, between the cable and the gripping element, around the whole of the cable’s periphery, and/or on the support surface. The electrically insulating material can namely be used in all places where different metals come into contact and can for example be a layer or a sleeve that comprises plastic or rubber. This prevents bimetallic corrosion that can occur if a galvanic cell is created when metals with different corrosion potentials are in contact and are subjected to an electrolyte, for example when a solar panel’s aluminium frame comes into contact with a galvanized steel wire.
The different components of the solar panel support structure can comprise or consist of any metal or metals, but can also contain non-metallic material.
According to an embodiment of the invention the solar panel support structure comprises at least two cables that are tensioned between a plurality of posts arranged at a distance from each other and arranged to extend substantially in parallel. According to an embodiment of the invention the attachment means of the fastening element is arranged to extend substantially at a right angle with respect to the at least two cables.
The present invention also concerns a solar cell park that comprises a solar panel support structure according to any embodiment of the invention and at least one solar panel mounted on said solar panel support structure. The present invention also concerns a method for constructing a solar panel support structure according to the present invention, which solar panel support structure comprises a plurality of posts arranged at a distance from each other and at least one cable that is tensioned between the posts, and/or for mounting at least one solar panel on the solar panel support structure. The method comprises at least one of the following method steps which are carried out with a fastening element that comprises a hook that is arranged to extend around part of a cable’s periphery and attachment means:
a) a cable is fastened to one of the posts in a way that prevents the cable from moving relative to the post, by fastening the cable between the hook and the post by fastening the fastening means to the post using the attachment means, and/or b) at least one solar panel is clamped between the cable and a support surface of a clamping component that is fastened to the fastening element using the attachment means,
whereby both method steps are executable with the same fastening element.
According to an embodiment of the invention at least one cable is fastened to one of the posts when the cable is in a tensioned condition. The cable can have a bias of at least 5 kN, at least 10 kN, at least 20 kN, at least 30 kN or more when the solar panel support structure is in use, depending on the amount and the weight of solar panels that are to be mounted thereon and on the wind and weather conditions where it will be mounted. Such a bias can for example be achieved by using an anchor that is arranged to at least partly be located in the ground/underlying surface. An anchor can be placed at the cable’s start and end and the cable can be fastened to the anchor and be tensioned to the right tensioning force. The cable can be tensioned or non-tensioned when at least one solar panel is mounted on the solar panel support structure.
The word’’cable” as used in this document can be a lead, a wire or a line, or a plurality or mixture of any suitable material(s), such as a steel- or plastic line, such as a Dyneema- line. The cable can have any cross-section geometry, not necessarily circular. The cable’s diameter or maximum cross-section dimension can for example be 10-16 mm.
According to an embodiment of the invention the fastening element fastenes a cable to a gripping element that is integrated in the post or arranged to be fastened to the post, which gripping element is arranged to extend around a part of a cable’s periphery, whereby the fastening element’s hook and the gripping element together extend around the whole of the cable’s periphery when a cable is fastened between the hook and the gripping element using the attachment means.
According to an embodiment of the invention the fastening element comprises a hook opening that is sufficiently large to receive the cable in the hook, whereby the fastening element is mountable on the cable directly in its mounting position.
According to an embodiment of the invention a plurality of solar panels are clamped between said cable and a support surface of a clamping component that is fastened to the fastening element using the attachment means.
According to an embodiment of the invention an electrically insulating material is applied in at least one of the following locations: between the cable and the hook, between the cable and the gripping element, around the whole of the cable’s periphery and/or on said support surface.
