Definitions

• the invention relates to a holder for a photovoltaic panel.
• the invention relates in particular to a holder for a photovoltaic panel, whereby the holder is suitable for use on a underground such as a flat roof.
• One type relates to unitary systems such as a plastic container having a bottom, a front wall, a rear wall and two side walls whereby the side walls are integrally connected to the front wall, the rear wall and the bottom, and whereby the side walls slope downwards from the rear to the front.
• the front wall and the rear wall at their top edges are provided with attaching means to which a photovoltaic panel can be attached to the holder at an inclination therewith.
• the container is weighed down by placing a number of stones or blocks of concrete in it.
• a disadvantage of this type of holder is that the container is voluminous en therefore difficult to handle in a situation wherein a holder has to be brought from a ground level to a roof by a person who has to cli b up a ladder in the process. Also, carrying a number of heavy stones or blocks to a higher level whereby a person makes use of a ladder is quite unfavourable.
• Another type of holder relates to a pillar-like support or column which is anchored tight onto an underground, for example by screwing the column onto the underground.
• a frame is mounted at the top side of the column, whereby a photovoltaic panel and a number of accessories are attached to the frame.
• This type of holder also has a number of disadvantages. The mounting and installing of such a holder requires a lot of work-time and sometimes special tools to do the same. Besides, quite a number of types of underground are not suitable for bearing pillar-like supports or columns thereon. Further, such types of holders are usually expensive.
• a holder for a photovoltaic panel whereby the photovoltaic panel can be provided at different angles.
• a holder for a photovoltaic panel comprising a first support member and a second support member for supporting a photovoltaic panel, which members when in use are connected to each other, whereby the first support member in use is at an angle with respect to an underground and the second support member rests on the underground, whereby each support member is provided with receptacle means, which receptacle means are provided for receiving means which shore the support members in their state with respect to each other, whereby each support member is provided with attaching means for at- taching the photovoltaic panel.
• the holder comprises two support members, it offers the advantage that the support members can be moved separately and that they are first connected to each other during the installing of the holder. Because the support members can be shored in their state with respect to each other first after shoring means have been received in their receptacle means, the holder can be kept in a compact and manageable size right up to its installation. It will be clear that the shoring means to be received are thus free of the support members till the shoring means are taken up in the receptacle means of the support members, for example at first when placing the holder.
• the shoring means may be of any material and have any form as long as they are stiff and stable in regard of changing wind loads and weather conditions.
• the first support member is pivotable between a folded- in state and a folded-out state at the said angle with respect to the second support member.
• the angle between the first support member and the second support member can be set in a number of folded-out states. This offers the advantage that the holder is suitable for use with photovoltaic panels of different sizes. This also is advantageous in regard of orientation of the photovoltaic panel with respect to light which is incident on it.
• the receptacle means are positioned such that when the shoring means are received therein, the shoring means serve to shore as well as weigh down the holder.
• This aspect offers the advantage that no separate means are required for shoring and weighing down.
• Some examples of such shoring means are concrete or gravel tiles or slabs, and stones.
• a suitable position and orientation of a receptacle means with respect to its support member is not at the ends in the longitudinal direction of the support member, but somewhere in-between these ends.
• An optimum position is determined by the form and dimensions of the shoring means to be used. For example, when using a rectangular block such as a closed concrete tile or slab, optimum shoring and weighing-down effects can be achieved by positioning the concrete slab such that the slab inclines upwards in the direction of the connection between the support members, at an angle of approx. 15-75 degrees with respect to the second support member, preferably at an angle of approx. 25-55 degrees and more preferably at an angle of approx. 45 degrees, and that the centre of gravity of the concrete slab is sufficiently close to the connection between the first support member and the second support member.
• the receptacle means of the first and second support members comprises a U-shaped beam, which U-shaped beam preferably comprises an edge for receiving the shoring means.
• shoring and weighing down can be done fast and simply, for example by placing a concrete slab with its one edge against the receptacle means of the second support member and tilting the slab such that it is received with its opposite edge in the receptacle means of the first support member.
• the edge may be provided with means with which small deviations in the size of the shoring means can be accommodated.
• the first support member is open at least in part. This is advantageous in that flow of air through the rear plane of the holder can take place, so that the holder experiences a lower wind load. Another advantage of the same is that a part of the space enclosed between the holder and a photovoltaic panel attached to it is accessible and because of that this space can be utilized for placing accessories such as batteries and cables therein. Another advantage of this accessible space is that during maintenance it is not required to first remove the photovoltaic panel. Also, a heavy accessory such as a battery which is further provided with an appropriate grip bar may be received in the receptacle means of the support members.
• a support member comprises two oblong parts which he substantially parallel with respect to each other whereby the related receptacle means connects the two oblong parts.
• This embodiment is favourable from the viewpoint of use of material.
• the receptacle means may be provided as being detachable so that during transport of a holder which is to be installed the holder can be moved in a form which is as compact as possible.
• connection between the first support member and the second support member can be set with respect to the longitudinal direction along the second support member.
• This flexibility in regard of its structure is advantageous in that the holder may be positioned close to a wall of a roof, for example, or contrarily be positioned as free-standing with a lot of space around it and that it is also suitable for use with photovoltaic panels which are positioned at different angles between the photovoltaic panel and the holder. This possibility of adjustment allows for adjustment of the receptacle means with respect to their respective support members.
• the second support member is provided with protruding means, on which protruding means attaching means for a photovoltaic panel are provided, preferably attaching means of which the height can be set with respect to the protruding means, whereby the protruding means are such that when the photovoltaic panel is attached, there is a through-flow area at the front side of the holder.
• protruding means on which protruding means attaching means for a photovoltaic panel are provided, preferably attaching means of which the height can be set with respect to the protruding means, whereby the protruding means are such that when the photovoltaic panel is attached, there is a through-flow area at the front side of the holder.
• shoring means which are to be received.
• Means for both shoring as well as weighing down the holder may be provided with such a flow surface that when air flows along the holder a down force on the holder is created.
• An example of an appropriate flow surface is that of semi-spherical shoring means of which the semi-spherical surface points downwards at an inclination with respect to and in the direction of the connection between the two support members.
• the protruding means are adjustable along the longitudinal direction of the second support member. This provides for another possibility of adjusting the angle of tilt between the photovoltaic panel and the holder.
• the first support member too is provided with protruding means, with attaching means for a photovoltaic panel provided on these protruding means. This allows for another possibility of adjustment of the angle of tilt between the photovoltaic panel and the holder.
• the protruding means may be foldable in and out with respect to its support member. This offers the advantage that the holder may be brought to a compact size. Also, the first support member can be held in its folded-in state by folding in the protruding means of the second support member. This is advantageous when moving a holder which is to be installed.
• the second support member may also be provided with height-adjustment means such as adjustable screws at the underside of the support member.
• height-adjustment means such as adjustable screws at the underside of the support member.
• the attaching means of the holder for attaching the photovoltaic panel are hook-shaped and they engage with a receptacle space provided for on the photovoltaic panel, whereby the width of the receptacle space is approx. as wide as the height of the hook-shaped attaching means, whereby the receptacle space at its inside is provided with one or more ribs which press against attaching means received in the recep- tacle space. This allows for simple and fast clamping attachment of the photovoltaic panel to the holder.
• a holder for a photovoltaic panel comprises two substantially vertically orientated oblong parts which are connected to each other by means of a first connecting member which is orientated laterally with respect to the oblong parts, whereby the plane in which the two oblong parts and the first connecting means he is open at least in part, and which further comprises two oblong parts which along substantially the whole of their length rest on an underground such as a flat roof and which are connected to each other by means of a second connecting member which is orientated laterally with respect to these two oblong parts, whereby the vertically orientated parts each are connected at their underside to one of the oblong parts resting on the underground, whereby these two connections are adjustable in a longitudinal direction along the oblong parts resting on the underground, whereby the first and second connecting means are U-shaped beams in which shoring means which weigh down, such as a concrete slab, are received, whereby the shoring means shore the vertical parts and the o
