Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application contains subject matter related to U.S.
application Ser. No. ______, entitled "Module Arrangement
Consisting of Solar Modules," filed on even date herewith.
BACKGROUND AND SUMMARY OF THE INVENTION
[0002] The invention relates to an arrangement consisting of solar
modules on surfaces, especially roofs.
[0003] Generic module arrangements are known from DE 100 47 400 C2
and from DE 20 2008 007 549 U1. These documents respectively
disclose solar module arrangements which are arranged by means of
mounting devices in a so-called folding arrangement on a roof, such
that they form a zigzag arrangement in a side view. This kind of
zigzag arrangement allows covering a roof area completely or nearly
completely with solar modules, thereby optimizing power generation
especially when the folding or zigzag arrangement is aligned in an
east-west direction.
[0004] The disadvantageous aspect in the two aforementioned
constructions and generally in the state of the art, with DE 10
2007 000 697 A1, DE 295 03 315 U1 and DE 199 34 059 A1 being
additionally mentioned with respect to the technological
background, is the high input of material with respect to the
mounting devices and the substructure. In particular, the known
mounting devices have a relatively large number of parts and
components.
[0005] Against this background, it is the object of the invention
on the basis of the generic state of the art to simplify the
generic arrangement with respect to its substructure and with
respect to the mounting device.
[0006] This object is achieved by a module arrangement, comprising
at least one or more double module arrangements, each arrangement
having two respective solar modules which are aligned at an angle
with respect to each other; wherein the edges of each double module
arrangement, which face away from one another, are not connected
with one another via a support strut.
[0007] In accordance with the present invention, the expensive
support profiles which are required according to the state of the
art can be omitted, especially the bottom support profiles and
cross members, or also the base struts. This leads to reductions in
the costs and simplified mounting.
[0008] The invention also provides the following subject matter as
a further development which can also be regarded as an independent
invention: a modular arrangement, in which adjacent double module
arrangements are connected with one another via at least one or
several coupling devices which comprise anti-slip devices that rest
on a base and are not fixed there with fasteners, with at least two
edges of two adjacent double module arrangements being arranged on
or fixed to each anti-slip device, preferably four of the
edges.
[0009] The term "solar modules" is not to be limiting and includes
a large variety of solar elements which form a kind of a
pre-mounted module and which are used for generating power in the
form of electricity and heat. The type of mounting (arrangement) in
accordance with the invention is suitable both for photovoltaic
modules and also thermal collectors, and can preferably be arranged
on flat roofs or slanted roofs, but also on free surfaces. Further
advantages are the aerodynamic arrangement of the solar modules, so
that weightings or anchorages can be avoided.
[0010] Furthermore, it is additionally provided according to an
especially advantageous variant of the invention that double module
arrangements which are adjacent to one another and which in
interaction then form a kind of zigzag arrangement are connected
with each other via coupling devices.
[0011] In accordance with the mentioned especially preferred
variant of the invention, these coupling devices form anti-slip
devices, i.e. they counteract sliding on a base. They rest on a
base preferably without any fastening means and are preferably
arranged in such a way that they have a relatively high static
friction on the base. Loading weights are therefore usually not
required.
[0012] At least two edges of two adjacent double module
arrangements are arranged on or fixed to each anti-slip device,
preferably four of the edges, so that double module arrangements
which are adjacent to one another and adjoin one another are
connected with each other in the region of the mutually adjacent
bottom edges via the coupling devices or elements which are
arranged as anti-slip devices. Simple mounting of the solar modules
is enabled in this way and a stable and secure installation is
realized.
[0013] Anti-slip devices for installing solar modules on flat bases
are known, e.g., from DE 10 2007 000 697 A1. It was not recognized
in DE 10 2007 000 697, however, that it is possible in a simple way
to use such as anti-slip devices directly for coupling adjacent
double solar module arrangements. As a result, an aerodynamically
closed and substantially "closed" surface area can be created which
allows omitting weights and the like for weighting the solar module
arrangements. The problem of erecting double solar module
arrangements can also be avoided, which arrangements are usually
relatively large and heavy because the specification only discloses
solar module arrangements with a solar module which is aligned in
one compass direction.
[0014] It is also appropriate and especially simple from a
constructional standpoint if the anti-slip devices are coupled via
at least one further connector with one or several double module
arrangements.
[0015] It is further especially advantageous if the anti-slip
devices also assume the function of load transfer of the double
module arrangements to the base.
[0016] Anti-slip devices are arranged in an especially preferred
manner in such a way that the distance between the bottom edges of
adjacent double module arrangements is 50 to 500 mm, preferably 300
mm, which again simplifies maintenance.
[0017] Preferably, the anti-slip devices are further arranged in
such a way that the intermediate space between mutually adjacent
double module arrangements is accessible.
[0018] In accordance with a further preferred variant, at least one
profile is arranged beneath the solar module, especially beneath
the glass-glass thin-film laminate modules, which profile comprises
one or several chambers which are configured for accommodating the
connectors.
[0019] A number of advantages of the invention mentioned below. A
mounting arrangement is provided which, in the preferred
configuration, makes do without any additional ballast or fixing to
the base. The mounting arrangement is especially also suitable for
unframed solar elements (laminate, preferably thin-film laminates
made from double safety glass). A separate substructure which is
fastened to the building is not necessary because the module
carries and supports itself. Wind guide plates can also be omitted.
And, an arrangement with a very high surface share of solar
elements is provided, which is characterized by controlled
unblocked discharge of water, good accessibility to the maintenance
access, and simple and secure laying of cables in the maintenance
access.
[0020] The employed anti-slip devices for maintaining the distances
between the rows can be regarded as an especially advantageous
further development of the invention and also as a separate
invention. The anti-slip device is used as a pressure element and
also for absorbing horizontal shearing forces by wind for example
and for connecting at least two bottom solar element edges.
[0021] The anti-slip device is preferably arranged as a support
plate for load transfer.
[0022] The connecting angles preferably consist of stainless steel
and are clamped into profile grooves, which are profile grooves
preferably of a profile of solar modules arranged as laminates with
a profile which is known as the so-called backrail (unframed
elements).
[0023] A tension element such as a traction rope can preferably be
provided between the profiles or between the connectors for
absorbing the pressure forces.

DETAILED DESCRIPTION OF THE DRAWINGS
[0037] FIG. 1 shows an exemplary module arrangement in accordance
with the invention which comprises at least two (as in FIG. 2) or a
plurality of solar modules 1.
[0038] In order to simplify the discussion, FIGS. 2 and 3 are
provided with a Cartesian coordinate system. The coordinates X and
Y respectively describe the coordinates of the base or erection
area for the solar modules which is assumed to be flat in this
case, and the supplementary coordinate Z indicates the coordinate
which is perpendicular thereto. In the case of a flat roof or
another flat base, the X and the Y coordinates correspond to this
area, whereas the Z coordinate respectively indicates the vertical
coordinate. This alignment explains the following terms such as "at
the top" or "at the bottom", which shall not be understood to be
limiting however, since the invention is also suitable for slanted
base areas such as a slanted roof for example.
[0039] Notice must be taken that although the term "solar module"
will be used consistently below, it shall be understood to include
modules of various kinds such as solar cell modules or thermal
modules.
[0040] The solar modules 1 of FIG. 1 preferably have a relatively
flat rectangular basic shape. Two of the solar modules 1 are
connected with each other by means of connectors 6, 7 which are
shown by way of example in FIGS. 6 and 7 in such a way that
respectively two of the solar modules rest on each other in pairs
in the region of one of their outside edges 3 and enclose an angle
.alpha. which is preferably but not mandatorily larger than
90.degree..
[0041] Preferably, a plurality of such double module arrangements
will be arranged one after the other in one row (direction X). It
is further possible to also arrange several of these rows of double
modules next to one another (direction Y) on a base such as a roof
in order to cover a roof area or the like as desired with solar
modules, especially also over the entire area.
[0042] The designation of a zigzag arrangement or folding
arrangement is obtained from this kind of arrangement.
[0043] The substructure has been simplified considerably as
compared with the state of the art.
[0044] The double module arrangements are respectively connected
with each other on the mutually facing edges 2 which are the
vertical upper ones in the installation position in the mounting
arrangement in accordance with the invention, but not in the region
of the bottom edges 3 which face away from one another.
[0045] Instead, a connection is realized by the base itself in the
mounted position. An additional connection to the base in the
region of the bottom edges which face away from one another is not
provided for or omitted within a double module arrangement.
[0046] As compared with the state of the art as known from DE 20
2008 007 549 U1, a double module arrangement with a considerably
simplified configuration is created because it is possible to omit
the intermediate supports and profiles which are provided there and
which connect the bottom edges of the double profile arrangement
which face away from one another. Preferably, no additional support
strut is provided between the connectors 6, 7 and the bottom edges
3.
[0047] Mutually adjacent and mutually adjoining double module
arrangements are further also connected with each other in the
region of the mutually adjacent edges 3 (which are the bottom ones
in this case) via coupling devices or elements. These coupling
elements preferably realize a spaced connection of the bottom edges
3 of adjacent double module arrangements in such a way that good
accessibility to the double module arrangements is ensured for
mounting purposes or maintenance work.
[0048] Preferably, the distance between the bottom edges 3 of the
adjacent double module arrangements is 50 to 500 mm, preferably 300
mm. The distance of the bottom edges 3 is preferably predetermined
by one or several coupling devices.
[0049] It is advantageous and has a stabilizing effect on the
construction if the anti-slip device is arranged to be roughened on
one side or is provided with a friction-increasing coating.
[0050] Preferred embodiments of these coupling elements will be
explained below in closer detail.
[0051] In an especially preferred embodiment, the coupling elements
or devices form integral or multipart anti-slip devices 4 (see
especially FIGS. 8 and 9).
[0052] The anti-slip devices 4 are preferably not arranged for
realizing an anti-slip device for the double module arrangements,
but also assume the function of load transfer to the base.
[0053] At least two edges 3 of two adjacent double module
arrangements are preferably arranged on or fixed to each anti-slip
device 4, preferably four of the edges 3, so that four of these
solar modules can be mounted or are mounted accordingly per
anti-slip device.
[0054] FIG. 2 shows a row of double module arrangements in a side
view, with the solar modules 1 as described in connection with FIG.
1 being arranged at an angle with respect to each other. The upper
edges 2 are kept at a small distance. The profiles 5, preferably
aluminum profiles which preferably comprise chambers used for
accommodating the connectors or other fasteners, are disposed
beneath the solar elements 1 (in this case a glass-glass thin-film
laminate).
[0055] A connector 6 is inserted at the upper edges 2 into the
recesses of two adjacent solar modules 1. The connector 6 (see FIG.
6) is preferably arranged as an integral angle piece (e.g.,
one-piece) and comprises two legs 11, 12 which enclose an angle
.alpha. (see reference 13).
[0056] In the preferred case this angle .alpha. is 160.degree.. As
a result, the solar elements 1 have an oblique inclination or
alignment of 10.degree. in relation to a flat base, e.g. a
horizontally aligned one.
[0057] The bottom edges 3 of adjacent double module arrangements
are also aligned to face one another in a larger collector field. A
connector 7 is also inserted into the profile 5 at the bottom ends
for mounting purposes. The connector 7 is thus fixed to the profile
5 and therefore to the solar module. It is possible to screw the
profile 5 and the connector 7 together. On the side facing away
from the edge 3 or the profile 5, the connector 7 is connected with
one of the anti-slip devices 4.
[0058] The anti-slip device of FIG. 8 is an especially preferred
embodiment. Embodiments of the invention are also possible in which
the bottom edges 3 of the solar elements 1 are connected directly
with one another.
[0059] The preferred anti-slip devices 4 absorb pressure forces
which are applied by the individual module rows as a result of the
10.degree. arrangement. The pressure forces cancel each other out
in general.
[0060] The anti-slip devices 4 are preferably provided with
protruding pins 8 (see FIG. 2), preferably threaded pins, on which
the connectors 7 are placed with respective boreholes for easier
mounting. It is then merely necessary to tightly clamp the
connectors 7 using a nut screwed on the threaded pins 8, on the
anti-slip devices.
[0061] The anti-slip devices 4 further preferably form a so-called
maintenance access between adjacent double module arrangements,
which considerably simplifies maintenance of the module arrangement
as already mentioned above.
[0062] FIG. 2 illustrates that no further profile mounting support
systems, no further cross beams within the double module
arrangements, no support struts or the like as described in the
state of the art are required.
[0063] The zigzag arrangement is formed in an especially preferred
way merely by the anti-slip device 4 between adjacent double module
arrangements, a connector 7 between the anti-slip device 4 and the
double module arrangement, a profile 5 on which the solar module is
arranged, a connector 6 between the upper edges, and profiles 5 of
adjacent solar modules of a double module arrangement. There can be
further adjoining connectors 7, anti-slip devices 4, etc.
[0064] A tension element can be arranged especially at the ends of
larger module fields for absorbing the pressure forces between the
profiles 5 or between the connectors 7. The tension element (not
shown here) can be a tension cable or a tension rod. As a result,
the entire module field is freely installable without any fastening
to the base or without weights. The aerodynamic arrangement further
prevents wind forces from attacking beneath the surfaces, so that
lifting off is not possible.
[0065] FIGS. 3 and 4 symbolically show a module field again, which
can be expanded and enlarged at will. FIG. 3 shows the sequence of
fastening which is important for this application and which
consists of the anti-slip device, connector, profile with solar
module, connector, anti-slip device, etc.
[0066] There are no connecting or supporting components beneath the
solar elements. Draining is easily possible, as is also access to
the modules.
[0067] FIG. 5 shows an enlarged sectional view of the profile 5,
which includes areas 9, on which the solar modules 1 (not shown
here) can rest and can, optionally, be tightly glued.
[0068] The profile 5 further comprises an open hollow chamber 10 in
which the connector or other mounting elements can be arranged.
[0069] The profile 5 is an especially advantageous option as a
holding element for the solar modules. It is alternatively possible
to fix the connectors directly to a module frame (if provided) or
any other part of the module, or to couple the same in special
fixing holes or the like for example.
[0070] FIG. 6 shows a sectional view of a connector 6 which
connects the two solar modules of a double module arrangement with
each other in the region of the mutually facing upper edges 2.
[0071] The connector 6 comprises at least the two legs 11 and 12
which are aligned at an angle with respect to each other.
Preferably, the angle .alpha. which is enclosed by the legs 11, 12
is between 100.degree. and 175.degree., preferably 160.degree..
[0072] Furthermore, the connector 6 preferably has through-holes
such as threaded bores on the legs 11, 12, which through-holes are
provided for simple clamping of the connector 6 by means of screws
in the profile 5.
[0073] FIG. 7 shows a double bent connector 7 which is configured
for fixing the bottom edges 3 of the solar modules 1. The connector
7 comprises a support leg 7a, a vertically aligned vertical leg 7b,
and a further oblique leg 7c for fixing to the solar modules, which
oblique leg is aligned in this case at an angle .beta. of
90.degree.+(180.degree.-.alpha.)/2=180.degree.-.alpha./2. The
connector 7 preferably further also comprises boreholes which are
configured for connection with the profile 5 or with the anti-slip
device 4.
[0074] FIGS. 8A and 8B show an anti-slip device 4 which is
substantially used as a connecting element between the bottom edges
3 of the mutually facing edges 3 of adjacent double module
arrangements.
[0075] The distance of the connection is chosen to be relatively
large at 300 mm, which leads to the advantage that a maintenance
access is formed between the double module arrangements. The
maintenance access is not mandatory, but is advantageously provided
for laying the power cables.
[0076] FIG. 8A shows a first anti-slip device 4 in a side view,
with the anti-slip device consisting in this case of a bottom sheet
15 on which at least one pressure rod 16 is arranged. Pins 17,
preferably threaded pins, are disposed on the pressure rod 16 which
can also be designated as a spacer rod. The pins 17 are for
connecting the anti-slip device with the connector 7 for the bottom
edges 3 of the solar modules 1.
[0077] FIG. 9 also shows an anti-slip device 4', which is arranged
without pressure rods for cost reasons. In order to provide the
sheet 15' with additional stability, especially pressure stability,
the sheet 15' is beveled at the edges. Additional beads or
stiffened portions of the sheet are further advantageous additions.
In addition to the pins 17, the anti-slip device 4' comprises
oblong holes 18 in the lateral beveled parts, which oblong holes
are used for fastening cable clips and the like.
[0078] The anti-slip device 4 can principally be provided on its
bottom side 19, therefore on its side facing the roof, with a
special configuration, preferably a roughened portion or a coating
for increasing friction.
[0079] It can be arranged as an adhesive surface, a gummed area, or
with strips such as EPDM strips or arranged in another manner such
that slippage of the elements on the base is prevented.
[0080] This is suitable since it is recognized that wind forces
acting on the module field only have a relatively low lifting
effect but a relatively large sliding effect, i.e. lower forces in
the vertical direction and larger forces in the horizontal
direction. The anti-slip devices are therefore suitable for
absorbing the respective wind loads without any additional
weighting and without any fastening to the roof or base area. The
standing area is large enough (preferably it is more than 200
mm.times.200 mm, especially more than 400 mm.times.300 mm) so that
the weight forces are well distributed. Preferably, the anti-slip
devices 4 will merely rest on a base and are not fixed there with
fasteners. This type of modular arrangement is especially
cost-effective, easy to mount and still especially secure.
[0081] This is shown particularly well in FIG. 10, which shows a
front view (y-direction) in FIG. 10a and a side view (x-direction)
in FIG. 10b of a double-row solar module arrangement. The
arrangement is provided in such a way that lifting off by wind is
prevented in a simple and secure manner.
[0082] FIGS. 11a, 11b show a side view of a further embodiment of a
connector 6 and a top view of the connector 6 with the two legs 11,
12 and the angle .alpha., which in this case is 160.degree.. The
legs 11, 12 are used for insertion into their respective chambers
of the profiles 5. In order to limit the insertion path of the
connector 6 into these chambers, at least one projection 20 is
arranged on the connector 6. It is especially advantageous when the
projection 20 is arranged centrally between the two ends of the
legs 11, 12 which face away from one another. A precise distance
between the solar modules is achieved in this manner, which
distance corresponds to the width of the at least one projection 20
or the distance between two projections for example. FIG. 11
further shows the mentioned threaded bores (reference numeral 21)
for the additional fixing of the connector 6 in the profile 5 by
screws.
[0083] FIGS. 12a, 12b show a side view of a further connector 7 and
a top view of the connector 7. This connector is also provided with
a projection (reference numeral 22) which delimits the insertion
path of the respective leg 7c into the chamber 10 of the profile 5,
so that a defined seat of the solar module or a defined seat of the
connector 7 on the solar module is easily ensured in this region of
the solar module, which is the bottom one in the mounted state.
FIG. 11 also shows threaded bores (reference numeral 23) and an
oblong hole 24, provided once for additionally fixing the connector
7 in the profile by screws and once for insertion on pins on the
anti-slip devices 4.
[0084] FIG. 13 finally shows a view of the tension element as
already mentioned above in the form of a tension cable 25 with the
fixing elements on ends facing away from one another for absorbing
the tensile forces between the profiles 5 or between the connectors
7.
