Description

The present invention relates to a method for building a roof structure having solar panels and a roof structure built up by means of such a method or a kit of a roof structure which can be built up by means of such a method. The present invention also relates to a method for dismantling such a roof structure.

In the prior art, solar power plants or solar panel constructions with a plurality of solar panels, guided or extendable solar panel arms in zigzag folds, which are also called fanfold folds in the following, are known.

The WO 2014/179893 A1 relates to a solar system with a plurality of solar panels arranged in a row and a rope on which the solar panels are held one behind the other. The solar panels can be moved along the rope.

In the CH 705 633 A1 discloses a photovoltaic system with a plurality of solar modules arranged at a distance from one another. The solar modules can be adjusted at an angle to ensure that snow will slide off.

For example concerns the US 2013/0186450 A1 a mobile solar power plant that can be set up and dismantled, in which, in the transportable state, a solar panel arm with a plurality of connected, relatively foldable panels is arranged in a container in a folded state according to a leporello fold and the solar panel arm for building the solar power plant on rails from the Container is extended laterally on the rail tracks, the solar panels of the solar panel arm being unfolded relative to one another when they are extended from the container.

Regarding the mobile solar power plant according to US 2013/0186450 A1 was recognized as a basis for the present invention on the part of the inventors that problems arise that laterally extended from the container solar panel arms take up a lot of space that can not be used otherwise, and also electrical lines to any electrical consumers or . Energy supply systems have to be relocated, and also the containers have respective additional lateral control rooms, which make it difficult to position the containers and their solar panel arms side by side.

The principle of extending a solar panel arm from a folded state is similar to the principle of US 2013/0186450 A1 according to a fan-fold fold on rails to form a solar panel arm construction having solar panels on a roof of a stationary building is also from the US 2011/0253193 A1 known. Here, however, it is only a matter of designing the permanently installed solar panel arm construction on the roof of the stationary building so that it can be flexibly retracted and extended depending on requirements and weather conditions or solar radiation. For mobile devices or constructions, the technical teaching is the US 2011/0253193 A1 not designed.

The object of the present invention arises on the basis of the prior art described above, in particular on the basis of the technical teaching of US 2013/0186450 A1 to provide a construction having several solar panel arms, which can be set up and dismantled in a space-saving and versatile manner, avoids the problems described above and at the same time can be set up and dismantled simply, efficiently and inexpensively and can be used easily, efficiently and inexpensively in a mobile manner, in particular when setting up and dismantling or using mobile solar power plants.

In order to achieve the above-mentioned objects, according to the present invention, a method for setting up a roof structure having solar panels on a floor surface is proposed. Furthermore, a roof structure built with such a method or a kit of a buildable roof structure according to claim 18 and a method for dismantling a roof structure built according to such a build method according to claim 17 are proposed. Dependent claims relate to preferred embodiments of the present invention.

A method according to the invention for setting up a roof structure having solar panels on a floor surface comprises: arranging a plurality of height-adjustable support elements on the floor surface, preferably in an arrangement with a plurality of rows of support elements preferably running parallel in a longitudinal direction; attaching a respective rail track extending in the longitudinal direction of the rows, preferably to upper ends of the support elements of each of the rows of support elements; Arranging a plurality of containers, preferably in the transverse direction, next to one another at one end of the rail strings, the containers preferably being opened towards the rail strings and in each of the containers a respective solar panel arm with a plurality of connected panels that can be folded relative to one another, preferably in a folded state according to a zigzag fold is arranged, and wherein, for example, some or preferably all or every second of the panels of a respective solar panel arm are designed as a solar panel; and / or extending the folded solar panel arms out of the containers on the rails in the longitudinal direction, the solar panels of a respective solar panel arms preferably being unfolded relative to one another when they are being extended out of the containers.

This has the advantages that an easily transportable and simple, quick, efficient, time-saving and cost-effective assembly or dismantling system or an associated assembly method can be provided for the formation of a roof or even hall construction with a roof having solar panels, which can be used particularly advantageously for the construction and dismantling of large mobile solar power plants. In addition, the zigzag folding of the solar panel arms results in a high level of stability and rigidity of the roof structure, e.g. B. against forces occurring in strong winds.

Depending on the local regulations, building permits are either not necessary or at least easier to acquire than for permanently installed roof structures, especially since it is advantageous not to have to provide a building foundation. In addition, the roof or solar power plant can be completely dismantled easily and sustainably without any residue left at the installation site. This also protects nature and the environment.

Even before transport, all or parts of the required components can be brought together simply, efficiently and inexpensively in a kit that is easy to transport, and a simple and inexpensive construction is also advantageously made possible, with no complex installation work being necessary. At the same time, the interior space created under the roof structure enables the provision of a large covered area under the solar panel arms as a fully usable, roofed and dry room, which can also be supplied directly with electrical energy and can therefore be used as a mobile factory hall, in which machines or factory equipment can pass through the integrated solar power plant can be supplied directly with electrical energy. Alternatively, the covered area can also be used as a parking space with an electric charging option for electric vehicles.

This also results in the advantage that the roof structure with integrated solar energy supply can be used or built up quickly and easily worldwide and is therefore particularly advantageous wherever an under-roofed space and energy are required quickly and easily, e.g. B. for refugee accommodation in crisis regions or for short-term needs, migrating construction sites or mining operations or also at research stations.

In addition, such a roof structure can advantageously be used as a warehouse, hall, accommodation or shelter, the required hall or warehouse height being advantageously adjustable as required by the height-adjustable support elements.

For efficient and inexpensive transport of the kit of the buildable roof structure, simple and inexpensive standard containers (e.g. size-standardized containers with a length of 20 or 40 feet) can advantageously be used, which if necessary can preferably be modified in such a way that they are on the long sides can be opened. In the assembled state, the containers can also advantageously form the walls of an emerging hall structure on one side of the roof structure.

The extension or pulling out of the solar panel arms from the containers can, for. B. by means of rails, wheels or slideways or sliding guides running on rail tracks, with an internal or external cable pull system optionally also being able to be provided on the solar panel arms.

According to an expedient, exemplary preferred embodiment, the construction method can furthermore include the lifting of the rail lines and possibly also the lifting of the unfolded solar panel arms arranged on the rail lines by adjusting the height of the support elements arranged on the floor surface.

This has the advantage that the height of the roof structure can be adjusted depending on the space required. Here it is possible to first assemble the rails at a low height in order to extend the solar panel arms out of the containers at low heights and then to set the predetermined height of the roof structure by simultaneously adjusting the height of the support elements (if necessary hydraulically, electrically and / or pneumatically controlled) .

In further exemplary embodiments, however, it is also advantageously possible to attach the rail strings to the support elements when the roof structure has already been set at a predetermined height, preferably approximately horizontally or at a predetermined angle of inclination on the already height-adjusted support elements, and to lift the container onto the rail strings to extend the solar panel arms, possibly by one or more cranes, lifting platforms, height-adjustable support elements or by placing the container on a pre-assembled scaffolding structure to accommodate the containers at the level of the rail tracks. The method here preferably includes lifting the container to rail line height.

This has the advantage that the height of the support elements can be precisely adjusted before the rail strings are attached, and the alignment of the rail strings can be precisely positioned parallel to one another at a predetermined distance and horizontally or at a predetermined angle of inclination before the solar panel arms are removed from the containers on the rail strings be extended.

The containers are preferably positioned directly next to one another in an alignment, possibly at the same time or in one operation. This has the advantage that the containers are tightly packed, i.e. H. can be precisely positioned in contact with one another or in attachment to one another and in a line transverse to the longitudinal direction in particular at a small distance from one another and thus a substantially closed roof can be formed in a simple manner from precisely positioned solar panel arms extended parallel to one another.

According to an expedient, exemplary preferred embodiment, the construction method can furthermore comprise the laying of a plurality of flat floor slabs, in particular concrete slabs or plastic slabs, the support elements preferably being arranged on the laid floor slabs. This has the advantage that a hall floor or a solid floor surface can be formed under the roof structure, so that the roof structure can be easily placed on a solid base that can be made flat before the support elements are positioned. Alternatively, it is possible to arrange the support elements on a flat concrete surface or on a solid floor surface.

According to an expedient, exemplary preferred embodiment, the rail strings can each be arranged in a horizontal orientation or at a predetermined angle of inclination, but parallel to one another, at the upper ends of the support elements. Here it is advantageously possible to set the alignment of the rail elements by adjusting the support elements in their set height before the rail strings are mounted. Alternatively, the height, the inclination or the horizontal alignment can be set by adjusting the heights of the support elements in the case of already installed rail sections, but preferably before the solar panel arms are extended from the containers.

According to an expedient, exemplary preferred embodiment, the upper ends of the support elements can be positioned at the same height or as a function of a predetermined angle of inclination of the rail lines to one another by adjusting the height of some or all of the support elements if the floor surface is uneven. This has the advantage that any unevenness in the floor or the floor surface can be compensated for by adjusting the heights of the height-adjustable support elements. Consequently, the construction of the roof structure according to the invention can take place not only on level ground, but also in a simple, but versatile manner, also on uneven ground surfaces.

According to an expedient, exemplary preferred embodiment, each panel of the solar panel arms is designed as a solar panel. Such an embodiment is optimally suited for building the roof structure in such a way that the longitudinal direction is oriented in the east-west direction or essentially in the east-west direction. If the solar panel arms are unfolded in such a way that the panels are not all horizontally aligned in the extended position, but still have a respective predetermined folding angle to one another (in particular like a fan-fold), then the solar panels of a solar panel arm are each aligned in pairs in such a way that a solar panel with East facing surface is inclined and the other is inclined with surface facing west. This has the advantages that the electricity generated is more evenly distributed throughout the day and that radiation reflected from opposite solar modules can be better used.

According to an expedient, exemplary preferred embodiment, every second panel of the solar panel arms is designed as a solar panel. In this case, such an embodiment is optimally suited for building up the roof structure in such a way that the longitudinal direction is oriented in the north-south direction or essentially in the north-south direction. If the solar panel arms are unfolded in such a way that the panels are not all horizontally aligned in the extended position, but still have a respective predetermined folding angle to one another (in particular like a fan-fold), then the panels of a solar panel arm are each aligned in pairs in such a way that a solar panel with North facing surface is inclined and the other is inclined with surface facing south. The orientation of the solar panel arms can then advantageously be selected such that only one of the panel pairs is designed as a solar panel and points in the direction that guarantees the higher solar radiation, ie in particular to the south when installed on the Northern hemisphere of the earth or to the north on the southern hemisphere of the earth.

According to an expedient, exemplary preferred embodiment, the roof structure is preferably designed to be closed at the top, preferably in that respective transversely adjacent panels of the solar panel arms are finally connected to one another in the unfolded state after moving out of the containers on the rails to form the roof structure closed at the top. This has the advantage that the roof structure can be closed easily and inexpensively at the top, in particular to be able to avoid the ingress of precipitation even in the spaces between solar panel arms that are adjacent in pairs.

In this case, adjacent panels can preferably be connected by means of plastic strips that can be attached between the panels, in particular made of transparent plastic material. This has the advantage that the connection can be made simple and inexpensive and also watertight. Alternatively, it is also possible to form the connection by means of tent tarpaulin sections.

The roof structure is preferably inclined in the transverse direction to a longitudinal side, so that precipitation, in particular rainwater or snow or thawed snow, collects on the roof structure in the transverse direction to the lower longitudinal side and is conveniently collected there in a channel running along a longitudinal direction to be advantageously fed to a further use, for example irrigation of fields, greenhouses or the supply to a public or private drinking water supply.

The panels are preferably heated at low temperatures in order to advantageously prevent an accumulation of snow on the roof structure and to reduce the roof loads.

The use of transparent or translucent material has the advantage that light can be let into the interior under the panel arms of the roof structure during the day and additional electrical lighting of the interior can be dispensed with at least during the day or at least the requirements for additional electrical lighting of the Interior can be kept lower. For this purpose, it is also or alternatively preferred that some or all of the panels or solar panels are designed to be transparent, in particular with transparent solar modules. This also makes it easier to use the roof structure as a greenhouse roof.

According to an expedient, exemplary preferred embodiment, the method can furthermore comprise attaching a plurality of wall elements to outer rows of support elements for forming a hall structure on the basis of the roof structure that has been formed. This has the advantage that a laterally protected interior space can also be formed under the roof structure in a simple and inexpensive manner. Here it is advantageously possible to close off one, several or all sides of the roof structure with wall sections or wall elements, wherein preferably at least one wall element can have an opening for doors or gates. Here it is furthermore preferred and advantageously possible that some or all of the wall elements are designed as solar panels, in particular in order to be able to further increase the solar yield.

As an alternative or in addition to the use of wall elements, the method can also include the attachment of one or more tent tarpaulin sections to outer rows of support elements for forming a tent structure based on the formed roof structure. This has the advantage that a laterally protected interior space can also be formed under the roof structure in a simple and inexpensive manner. Here it is advantageously possible to close off one, several or all sides of the roof structure with wall sections or wall elements.

According to an expedient, exemplary preferred embodiment, the method can furthermore include removing the arranged containers after the solar panel arms have been extended from the containers. This advantageously enables a roof or hall construction that is closed on all sides without space-reducing containers.

Alternatively, however, the containers can also remain in their position after the solar panel arms have been extended. This has the advantage that any required energy converters (e.g. direct current / alternating current converters and / or electromagnetic transformers) or electrical installation devices electrically connected to the solar panel arms can be provided in the containers and protected in the containers against wind and weather or precipitation as well as can be protected from unauthorized human interference. In addition, this has the advantage that dismantling the roof structure is simplified, since to retract the solar panel arms to be dismantled into the container, they do not have to be precisely repositioned and / or lifted if they are precisely positioned, but rather the solar panel arms can simply be retracted after opening the container.

According to an expedient, exemplary preferred embodiment, respective adjacent panels of a solar panel arm that can be folded or unfolded relative to one another can be movably connected to one another by means of an articulated connection and / or by means of one or more plastic strips or tarpaulin sections, in particular made of transparent material. The plastic strips or tent tarpaulin sections have the advantage that the interior space under the roof structure can be protected against precipitation easily and inexpensively. The use of transparent or translucent material offers the advantages described above of the incidence of light into the interior during the day.

According to an expedient, exemplary preferred embodiment, the solar panels of a solar panel arm can have one or more respective electrical plug connections for electrical connection to one or more electrical consumers, to an energy supply system and / or to one or more other solar panels of the same solar panel arm and / or other solar panel arms of the roof structure exhibit.

This has the advantage that the electrical connection of the solar panels with one another, with a power grid, with energy converters or with storage devices for storing electrical energy can be carried out simply and inexpensively during the construction, since the cabling and plug connections are already provided.

The plug connections already provided have the additional advantage that, on the one hand, high voltages can be avoided during construction, since the solar panels can only be electrically connected to one another or to a power supply device when the roof or hall construction is completed, and this also enables this, especially when the panels are connected to Lips, for example in the form of a tongue and groove engagement, for example in the form of a piping connection, a simple and inexpensive replacement of individual solar panels or solar modules in the event of a defect.

According to an expedient, exemplary preferred embodiment, the solar panels of a solar panel arm can each have a plurality of solar modules on their respective surface, which are arranged on a panel structure, in particular a panel frame or a panel plate. The solar modules can comprise one or more solar cells or photovoltaic cells. In addition, in further exemplary embodiments, thermal solar collectors can also be integrated for connection to a treatment system that can be set up under the roof structure for warming up water with solar energy.

According to an expedient, exemplary preferred embodiment, each panel structure can have a water-impermeable layer, and the water-impermeable layer in particular can have a water-impermeable connecting material. This has the advantage that the interior can be better protected from precipitation.

The aspects described above or their individual features describe preferred embodiments of the invention, but the invention is in no way to be interpreted as being restricted to these aspects and features, but rather other exemplary embodiments are conceivable and belong to the invention insofar as they fall under the independent claims. In particular, it should be pointed out that further exemplary embodiments can be formed solely by any combination of the above aspects and their individual features, although these are not individually described or enumerated solely due to the large number of possible combinations.

Furthermore, according to the present invention, a method for dismantling a roof structure constructed according to a method according to one of the preceding aspects can be provided, which comprises moving the solar panel arms into the container on the rail strings arranged on height-adjustable support elements in the longitudinal direction until each of the solar panel arms is folded State is arranged in the respective container, and after retraction of the solar panel arms, the roof structure of the rail tracks and the height-adjustable support elements is dismantled.

Furthermore, according to the present invention, a roof structure can be provided which is or can be built up according to a method described above or is or can be dismantled according to a method described above.

In particular, according to the invention, a kit of a roof structure which can be built up according to a method described above or which can be dismantled in the built-up state according to a method described above, comprising: a plurality of height-adjustable support elements which, when the roof structure is built on the ground surface in an arrangement with a plurality are arranged by rows of support elements running parallel in a longitudinal direction; a plurality of rails, which when building the roof structure in the longitudinal direction of the rows at the upper ends of the Supporting members of respective rows of supporting members are arranged; and / or a plurality of foldable solar panel arms which are designed to be extended in the longitudinal direction from respective containers that are open towards the rail lines when the roof structure is set up on the rail lines.

The kit preferably furthermore has a plurality of containers which can be positioned directly next to one another in the transverse direction in an alignment.

In summary, the invention and its numerous exemplary embodiments advantageously make it possible to provide a construction having several solar panel arms, which can be assembled and dismantled in a space-saving and versatile manner, avoids the problems described above and at the same time is easy, efficient and inexpensive to assemble and dismantle and is simple, efficient and can be used inexpensively on a mobile basis, especially in the construction and dismantling or use of mobile solar power plants.

It should be emphasized that the present invention is in no way limited or restricted to the exemplary embodiments described below and their design features, but can also include further exemplary embodiments and modifications of the exemplary embodiments, in particular those that are made possible by modifications of the features of the examples described or by combining one or more of the features of the examples described are included within the scope of protection of the independent claims.

In 1 is the exemplary roof construction 1 with an optional side panel or wall panel with side-mounted wall elements 8th shown, this represents an exemplary embodiment of a hall structure based on an embodiment of a roof structure according to the present invention. The exemplary roof construction 1 without the optional side cladding or wall cladding is in 2 shown.

Examples include the flat floor surface laid out of parallel floor slabs 2 a plurality of height-adjustable support elements 3 arranged in rows which are each positioned parallel to one another in the longitudinal direction. Examples are in 2 ten parallel rows of support elements 3 shown, which extends as an example from diagonally lower left to diagonally upper right in 2 extend.

On the rows of height-adjustable support elements 3 are respective rail lines 4a and 4b arranged, each extending along a respective row in the longitudinal direction and consequently parallel to one another. Here are the rails 4a and 4b for example, each arranged in pairs in such a way that a distance between the rail lines 4a and 4b a pair of rails depending on a width of the solar panel arms described later 6th is set. Adjacent rails 4b and 4a different pairs of rails arranged next to one another are on the other hand arranged in such a way that they run parallel to one another essentially directly next to one another and a predetermined minimum distance of, for example, less than or equal to 50 cm or preferably less than or equal to 20 cm is not exceeded.

On every pair of rails 4a and 4b is a respective solar panel arm 6th (for example, a total of five solar panel arms in 2 In the longitudinal direction movably guided or arranged stored. The solar panel arms 6th include, for example, a plurality of panels that are foldably connected in pairs 6a and 6b (see also 3 ), which are designed like a fan-fold or according to a fan-fold. 2 shows the arrangement of the solar panel arms 6th in an unfolded state of the formed roof structure, the panels of the respective solar panel arms preferably having a folding angle.

The panels preferably all have parallel solar panel arms 6th each have the same folding angle, and also are adjacent panels of adjacent solar panel arms 6th preferably inclined at the same angle and positioned identically in the transverse direction (or in each case arranged in an alignment in the transverse direction), so that the panels of adjacent solar panel arms 6th advantageously with a closing connection z. B. can be joined together or connected by means of plastic strips or tarpaulin sections to complete the roof structure.

The predetermined folding angle can, for. B. by provided fixing system, such. B. fixation ropes or fixation cables set or adjustable set.

The principle of building the roof structure 1 according to one embodiment is with reference to FIG 3 and 4th evident. The support elements are preferred 3 Positioned in the rows in the longitudinal direction and set to a predetermined height of the roof structure, here for example at the same height on a flat ground or a flat floor surface 2 , in such a way that after setting up the height-adjusted support elements 3 the rails 4a and 4b be placed and attached or fixed, in particular, for example, in a horizontal extension in the longitudinal direction.

At one end of the parallel rails 4a and 4b is exemplified by a plurality of containers 5 Placed side by side in transverse direction and with one side of the container that can be opened facing the rails 4a and 4b arranged indicative. Standard containers can be used here (e.g. standard containers 20 feet or 40 feet long) or modified standard containers which are or can be opened to the longer side of the container.

In the containers 5 are prior to building the roof structure 1 the respective solar panel arms 6th arranged in the folded state according to fan-fold folding, the panels 6a and 6b preferably in the completely folded state in the containers 5 are arranged parallel or with a folding angle of essentially 180 degrees (see 3 ).

In the construction of the roof structure 1 become the container 5 preferably raised to rail line height so that the solar panel arms 6th on the rails 4a and 4b can be extended (see 4th ), particularly preferably up to the predetermined angle of inclination between all adjacent panels 6a and 6b essentially over the entire length of the roof structure 1 is reached and adjacent panels 6a and 6a or. 6b and 6b adjacent solar panel arms 6th are positioned to each other (preferably lying in one plane) (see 1 , 2 and 3 ).

In 4th the containers are positioned, for example, in such a way that a lower side of the container 5 is positioned at rail line height. 5 shows an alternative exemplary embodiment in which the panels 6a , 6b also vertically in the container 5 are aligned and on a top of the container 5 be extended, preferably an upper side of the container 5 is positioned at rail line height. The vertical arrangement of the panels 6a and 6b when folded in the container 5 reduces the risk of mutual scratching during transport compared to, for example, horizontal storage in the container 5 .

6th and 7th show an exemplary foldable connection of adjacent panels 6a and 6b , whereby for north-south orientation only one - ie preferably every second - of the panels 6a and 6b as a solar panel 6th can be designed with solar modules or alternatively both - ie preferably all - panels 6a and 6b of the solar panel arm 6th can be designed as solar panels with solar modules.

Examples include the panels 6a and 6b one panel frame each 10 , being on one side of the panel frame 10 one plastic strip each 9 to form the foldable connection of the panels 6a and 6b arranged and on the respective sides of the panel frame 10 is attached, for example in accordance with an example of dimensionally accurate (for example, releasable by pushing out in the transverse direction) groove connection according to 7th . In preferred embodiments, the plastic strips are 9 made of transparent or translucent plastic material. In further exemplary embodiments it is it is also possible to design the panels themselves or the solar panels to be translucent.

Unfolding or folding the panels 6a and 6b to each other is by elastic bending of the plastic strip 9 easily possible, and in addition, the connection for protection against precipitation can thus be designed such that it is water-impermeable.

Similarly, in the unfolded state, neighboring panels of neighboring solar panel arms can also be connected with plastic strips or alternatively with tent tarpaulin sections in order to be able to provide even better protection against precipitation and the entire roof structure 1 to train closed.

Another advantage of the invention can be seen in the exemplary illustration of FIG 8th , in which a roof structure according to an embodiment on an uneven floor or an uneven floor surface 2 is placed so that the lower sides of the support elements 3 cannot be aligned at one level. By adjusting the height setting of the height-adjustable support elements 3 however, a state can advantageously be set in which all the upper sides of the support elements 3 be positioned at a height or at least in a plane corresponding to a predetermined angle of inclination in order to align the rail lines 4a and 4b despite the unevenness of the floor surface 2 to be able to align precisely.

In 9 an exemplary development of the invention is shown. In the transverse direction of adjacent rails 4a and 4b supporting pillars 3 are each through two diagonal struts 11 connected with each other. All adjacent pillars can be used 3 adjacent rail lines 4a and 4b be braced together. Alternatively, there are just a few supporting pillars 3 Connected to one another in the transverse direction by diagonal struts, for example every second, third, fourth, etc., is a supporting pillar 3 a rail track 4a each with a second, third, fourth, etc. support pillar 3 of an adjacent rail line 4b connected. The diagonal struts 11 prevent the structure from tilting in the transverse direction.

In 9 are, for example, preferably also diagonal corner struts 12th between the rails 4a , and 4b and the pillars 3 intended. Any or some support pillars 3 are expediently with one or two opposite corner struts 12th with the associated rail track 4a and 4b firmly connected. The corner struts prevent the supporting structure from tilting in the longitudinal direction.

It should be emphasized once again that the present invention is in no way limited or restricted to the aspects, exemplary embodiments and their design features described above, but can also include further exemplary embodiments and modifications of the exemplary embodiments, in particular those that result from modifications of the features of the described Examples or by combining one or more of the features of the described examples are included within the scope of protection of the independent claims.

Further possible and advantageous aspects arise, for example, as follows:

• The longitudinal direction of the roof or hall construction during construction (installation of the PV hall or photovoltaic hall) can take place in different spatial directions to optimize the electricity demand depending on the local conditions, e.g. E.g .: approximate east-west alignment of the longitudinal direction of the solar panel arms or PV modules (photovoltaic modules or solar panels 6a , 6b ) to generate electricity that is as uniform as possible over the course of the day with relatively high levels of generation in the morning and evening; approximate south orientation of the longitudinal direction of the solar panel arms 6th or PV modules (photovoltaic modules or solar panels 6a , 6b ) and use of non-photovoltaically active areas on the areas facing north to maximize the yield per module (or in the southern hemisphere exactly the other way around), ie, z. B. every other panel 6a , 6b of each solar panel arm 6th can be used as a solar panel 6a , 6b be designed and possibly also an optimization of the setting of the predetermined inclination or folding angle of the PV module surfaces or solar panels 6a , 6b in the unfolded state and / or setting an angle of inclination of the rail tracks to site-specific conditions.

The use of transparent materials between the PV module surfaces or between the panels is also advantageous 6a , 6b and to connect several PV module tracks or solar panel arms 6th to better illuminate the building or the roof or hall structure with daylight.

The use of transparent PV modules or solar panels is also advantageous 6a , 6b to better illuminate the building or the roof or hall structure with daylight.

A possible exchange of individual PV modules or solar panels is also advantageous 6a , 6b through transparent materials to better illuminate the building or the roof or hall structure with daylight, e.g. B. in the northern hemisphere instead of PV modules glass surfaces or transparent tarpaulins or plastic surfaces in the north-facing areas when building the roof structure with south-facing modules or solar panel arms 6th .

The design of side walls with PV modules or solar panels is also advantageous 6a , 6b to maximize power generation per floor area.

An exemplary option for heating the PV modules or solar panels is also advantageous 6a , 6b (e.g. by applying a reverse voltage) and / or heating the PV module frames or panel frames or PV module lower edges to reduce yield losses due to dew, snow and ice and to reduce maximum roof loads.

Associated electrical installations, such as B. inverters, batteries or accumulators, transformers, etc., can advantageously be placed under the roof structure in a protected manner or preferably in the containers 5 remain.

In addition, a simple cleaning z. B. be carried out automatically by robots, especially when the roof structure is closed.

In particular, it should be pointed out that the large closed (roof) area formed by exemplary embodiments of the invention advantageously enables the greatest possible use of space and leads to the greatest possible power generation per base area. Assuming a module efficiency of z. B. 15% are with east-west orientation of the PV modules or solar panel arms 6th maximum output of approximately 1.5 MW per hectare possible, while conventional arrangements only achieve values about half as large due to non-photovoltaically active free areas between the modules.

The direct inclusion of the PV modules or solar panels 6a , 6b into the roof construction and the high inherent strength of the fan-fold arrangement allow very low construction costs and a stiff and stable roof or hall construction that can be set up and dismantled in a mobile manner with a directly integrated energy supply through solar energy.

In summary, the invention and its numerous exemplary embodiments advantageously make it possible to use a plurality of solar panel arms 6th to provide a construction that is space-saving and versatile, can be assembled and dismantled, avoids the problems described above and at the same time is easy, efficient and inexpensive to assemble and dismantle and can be used easily, efficiently and inexpensively on a mobile basis, in particular during assembly and dismantling or dismantling. the use of mobile solar power plants.
