Abstract

A solar module (22) is connected to a carrier plate (24). Electrical connections of a solar shingle (10) are formed as a plug (20) or socket (18) which can be connected directly to a socket or plug on the roof or facade side, or of an adjacent solar shingle.

Description

The invention relates to a roof and facade cladding comprising one or more solar shingles with a support plate pointing towards the roof or facade, one with the carrier plate connected and covered by this solar module and one at that of the carrier plate opposite Arranged on the side of the solar module, covering the solar module, with the solar shingles electrical connections as well as mechanical fasteners have, which with corresponding electrical connections or mechanical holding means interact.

When covering or cladding of roofs and facades with solar shingles, i.e. Solar power modules exist in addition to the problem of weather protection or the sealing function against rain, there is always the problem of the electrical connection.

It is problematic here that Roofers usually have inhibitions when laying electrical connections and cabling of common solar modules have. It is therefore another trade besides the roofer, namely an electrician or solar installer on the roof is necessary.

To avoid this, put one Series of solar shingle manufacturers the touchproof plugs of the Swiss company Multi-Contact (MC connector).

On the one hand, these plugs are relatively expensive and not that easy to make the connection.

There is also MC connectors such as also with other used flat plugs, for example from the company Atlantis, the problem that from every solar shingle cable with one Protruding plugs, which in most cases are before the final mechanical Fixing the shingles must be connected.

But also as far as an aftermarket electrical Shingles can be contacted is the disadvantage that such connections are relatively prone to errors and the interconnection of the different solar shingles with each other to strands is inflexible.

The invention therefore turns the Task to provide a roof and facade cladding that provides a simple electrical connection technology so that such solar shingles easily from one Have roofers laid.

The invention solves this problem by a roof and facade cladding, in which the electrical connections of the Solar shingles are designed as a plug (socket) and the plug (Socket) directly with a socket (plug), the roof or is attached to the facade or to adjacent solar shingles, is connectable.

This will in particular Advantage achieved that only relatively robust plugs or sockets are attached to the solar shingles and no cables from them protrude.

In particular, it can be provided that the solar modules over Contact strip, for example aluminum ribbons with a thickness of approx. 0.1 mm, connected to the electrical connections are.

It is particularly advantageous if the electrical connections simultaneously with or after the mechanical fastening of the solar shingles the facade or roof or adjacent shingles can be connected. This offers the advantage of laying the shingles themselves can be done without current, unlike many conventional systems, where the wiring must be carried out before the roof or facade shingles in their final Position.

This will cause the laying through a roofer significantly simplified.

It can be particularly advantageous if the electrical connections with mechanical hanging the shingles automatically with the corresponding electrical connections connected on the roof or facade side or on adjacent solar shingles become. This will become the source of the error when connecting the Solar shingles further decreased since the one who made the shingles only mechanically fasten the shingles by he engages the fasteners with the holding means. The electrical contact, i.e. the plugging in of the plug into the socket, then takes place automatically, without further action necessary is.

The electrical connections can be in the mechanical fastening or holding means can be integrated. Alternatively, however, it is also possible to use separate ones electrical connections to be provided, which are positioned and designed such that they simultaneously engaged with each other with the fixing of the shingle to be brought.

As an alternative it can be provided that contact plates on the shingles as electrical connections are arranged, which have resilient mating contacts on the roof or facade side or interact on adjacent shingles. This will in particular The advantage achieved is that when the contact plate and the resilient mating contacts are not dimensioned too small, in any case, i.e. also at not optimal installation for closing the contact comes when the mechanical connection is established because of certain construction tolerances as well as tolerances during assembly.

It can be provided that the shingles are mechanically and electrically connected to each other to form strands, the strands then being connected at their ends to the roof or facade construction. Alternatively, it can also be provided that each clapboard with the lower construction of the roof or facade and only to make the electrical contact in series or in parallel to strings of shingles with each other. Finally, each shingle can be connected to the substructure of the roof or facade both mechanically and electrically. For this purpose, it can be provided that both the mechanical fastening means and the electrical connections are arranged on the roof-side or facade-side side of the carrier plate or the cover, provided that the cover projects beyond the carrier plate.

When connecting the shingles, which are arranged side by side, with each other a side Arrangement of both mechanical and electrical fasteners be provided so that the contacts when pushed sideways the shingles are closed.

Even if the electrical connections of each Shingles on the roof or facade side of the shingles are arranged, it can be provided that the connections of the individual connections for example from the outside the finished clad facade can be closed. For this can be provided that the roofer with a special tool the contacts arranged on the side of the shingles, for example through the slots between the shingles brings in contact.

This can be provided in particular if the electrical connections are designed as rotary plugs and rotary sockets are, each with a rotary plug and a rotary socket for formation of an electrical contact rotatable with each other in engagement are. It can in particular be provided that each shingle one rotary plug and one rotary socket on opposite Side edges of the shingles are arranged and the shingles through Rotation of the two parts of the rotary plug and the rotary socket with neighboring ones Shingles are electrically connected.

For a particularly preferred one embodiment can also be provided that a molded part on the shingles is laminated on. The molding can be laminated on, for example directly during the manufacture of the shingles. Especially if it is shingles, in which the cover the carrier plate towering in one direction can for example made of cast resin existing film with which the solar module between the two panes (Cover and carrier plate) is laminated, pulled out and it can be a plastic rail with an integrated plug and / or fastening means material fit be connected to the shingle. The contact strips that hold the solar module can connect with the plug thereby led out be over for example the plug is put away. Now the plug is in contact with the counterpart brought, the contact ribbon is through the counter contact deformed and the contact closed.

As a mechanical fastener can pens, Find bolts or hooks. However, screws can also be used etc. be provided on the roof or facade side with corresponding holding means or with appropriate holding means on adjacent shingles are arranged to cooperate.

It can be provided that the solar module does not overlap the entire area the carrier plate and / or cover, which in particular enables that such solar shingles overlap in a conventional manner for roof shingles can be relocated and so the rainproofness of the taper is guaranteed.

The resin 80 for embedding the solar module 74 between carrier plate 72 and cover 70 is towards the free edge 76 the cover 70 over the carrier plate 72 led out and serves to laminate a rail with a plug 78 who so with the clapboard 10 is materially connected. The contact strips 58 are also in the direction of the free edge 76 the cover 70 over the carrier plate 72 led out and are through a hole in the connector 78 passed through so that they are on the noses 82 of the connector 78 come to rest. Now the socket is used as a counter contact as in the illustration 12B shown on the plug 78 attached, so the contact strips 58 into the recess 82t of the connector 78 pressed in so that the electrical contact is closed.

This configuration enables a particularly good degree of pre-assembly of the shingle 10 to reach.

In 13 is a further embodiment of a roof shingle 10 shown, in which only a part 62 is occupied with the solar module. The carrier plate 72 points in turn towards the roof and only covers the solar module 74 from. The cover 70 extends over the part 62 in the direction of the arrow 71 via the solar module 64 out. The contact strips 58 are like in 12 towards the free edge 76 the cover 70 over the carrier plate 72 led out and in this area with an electrical contact 90 electrically connected. The contact 90 when laminating the shingle 10 mitauflaminiert. It can be made from an electrically insulated spacer ring, which is also laminated in the same operation 92 (Presentation 12B ) be surrounded. This creates a socket 20 with an appropriate connector (not shown) for the electrical connection of the solar shingle 10 can be used. This connector can also be laminated in the same operation 94 , the Z. B. can consist of stainless steel, and bolt on it 96 at the socket 20 be attached. The arrangement can also be reversed, so that instead of the socket 20 a plug is formed. This can be done by the contact 90 as a plug, for example by applying a bolt to the contact 90 is trained.
