Definitions

  • the present invention relates to a device for roofing and / or as a substructure for modules for the conversion or bundling of solar energy, in particular modules of a photovoltaic or solar collector system or mirror of a solar thermal power plant.
  • the present invention further relates to a device for tracking modules for converting or bundling solar energy, in particular a multi-module photovoltaic or solar collector system or mirrors a solar thermal power plant, according to the position of the sun.
  • photovoltaic systems but also solar collector systems are therefore already variously designed so that the modules are rotatable about an axis and their orientation at any time in terms of their yield or the generated electrical or thermal power is maximum.
  • the modules have also been rotated or swiveled around two axes to track the sun.
  • One example is the photovoltaic plant near Kleinwulkow in Saxony-Anhalt.
  • Another example is provided by Ecoware SpA, Via Terza Strada, 7, 35129 Padova, Italy.
  • conventional biaxial systems have the disadvantage that very large modules are tracked. To accommodate weight forces and corresponding moments and wind forces therefore large, expensive and heavy devices and drives are required. Moreover, these are not suitable for many applications, for example for installation on a flat roof of a building.
  • Another object of the present invention is to provide an improved apparatus for tracking modules for converting or concentrating solar energy.
  • the present invention is based on the idea to provide a plurality of structural modules, each comprising at least one substantially vertical structural support and a horizontal support frame, which are interconnected at their outer edges.
  • Structural support and supporting frame of each structural module are one or two axes rigid (ie rigid in one or two directions) connected to each other.
  • the single structural module does not have to be stable. Rather, it is sufficient that a stability of the entire device is created by a mutual lateral support of the individual structural modules. This in turn can be dispensed with a foundation on (low-lying) foundations. Instead, every load Plant support simply on the terrain surface or the ground, in particular an asphalt or concrete surface of an existing parking lot, rest.
  • the device is thus similar to a table, which consists of several modules, each comprising one or more legs or structural supports.
  • the costly creation of foundations and the required in the case of an existing parking lot usually required relocation or diversion of supply and disposal lines for water, sewage, drainage, gas, electricity, data, etc. can therefore be omitted.
  • the total costs can be kept so low that they can be partially or completely amortized by remuneration from the supply of electrical energy in a power grid.
  • Another advantage is that the device can be erected and dismantled simply and inexpensively due to the omission of a foundation and is therefore also suitable for temporary or short-term use in changing locations.
  • Foundation-free means preferably that the structural support rests on the original, undeveloped underground, for example on an existing gravel, grassland, asphalt or concrete surface.
  • foundation-free means that there is no foundation between the supporting column and the ground, which reaches into a depth that can be considered frost-free at the given location.
  • connection between structural support and ground can be designed so that horizontal forces are absorbed or transmitted only by static friction between the supporting structure support and the substrate.
  • pegs or a buried in the underground profile can be provided at the bottom of the truss prop.
  • the device preferably also has one or more roof surfaces for the protection of the underlying areas from the weather, in particular for shading and / or for the discharge of precipitation.
  • each roof structure is preferably assigned to each structural module.
  • a roof surface comprises a membrane with a central opening, in which the supporting structure support of the associated structural module is arranged, wherein the membrane is pulled towards the edge of the central opening in a funnel shape downwards.

  • the roof surface consists of prefabricated elements.
  • Modules for the conversion or bundling of solar energy are, for example, modules of a photovoltaic or solar collector system or mirrors of a solar thermal power plant that focus or concentrate solar radiation on a heat exchanger in which high temperatures are generated.
  • steam is generated which then drives a turbine coupled to a generator.
  • the device can also be used alone as a canopy, which carries no photovoltaic or solar collector system or mirror. Also in this case, the favorable production costs represent a major economic advantage.
  • the device is not only usable at ground level on paved, concreted or green parking lots but also on other surfaces advantageous.
  • the device can also be mounted on an existing flat roof of a building with little effort and thus with low creation costs. Instead of an anchorage, which would require a complex intervention in the existing structure of the building and the flat roof, the device can be easily placed on the existing surface of the flat roof.
  • the lower ends of the structural supports thereby extend through a substrate layer of a green flat roof, through insulating layers or through a gravel filling and lie directly on load-bearing structures of the roof.
  • the structural supports are preferably located there on the flat roof, where it is supported from below, for example by supporting outer or inner walls or by vertical structural supports in the building.
  • the device is preferably trackable to the position of the sun and particularly preferably comprises one or more modules which are rotatable about an axis oriented in north-south direction.
  • the device comprises a torsion tube substantially parallel to the axis to which the module or modules are connected.
  • the rotation about the axis preferably takes place with an electromotive drive via a self-locking gear, in particular a worm gear.
  • a worm gear allows for easy adjustment of the modules in any angle range.
  • each one or more modules is a biaxial tracking of the pho- photovoltaic or solar collector plant according to the position of the sun.
  • This biaxial tracking system ensures particularly efficient utilization of the installed photovoltaic or solar collector area by constantly adjusting the angle of the modules to the first axis to a current optimum value.

Particularly in the case of a parking lot, an advertising message projected onto the roof surface or other information may be moved under the control of motion sensors with a moving vehicle or a moving person.
  • a moving vehicle or a moving person can move along with it. provided sound, which in turn is controlled by motion sensors.

  • the owner, tenant, tenant or otherwise authorized user of the parking space or other reason does not create the device.
  • a creator concludes a contract with the owner, tenant, tenant, or otherwise beneficial owner of the cause, creates the device, and generates revenue as described above.

  • the device described thus has up to three independent functional levels or use levels, which can also be used economically independently.
  • the uppermost level which may also be referred to as a "collector level" may be used for generating energy and resources via a solar power plant installed there or at least partly there to generate electrical energy or heat, the heat also being used to cool or air-condition buildings or other facilities.
  • the roof level for example, designed as a membrane, can serve as a shelter for protection against sun, rain or other rainfall, generally as weather protection. It can also be used as an advertising medium, multimedia playable via projections, rear projections, sound reinforcement or printing. In addition, rainfall can be collected for local disposal, storage or use.
  • the ground level can be used as a parking area for cars, as storage areas, as a space for markets, or as a cultivable, agriculturally usable area with its own irrigation via the membrane cone.
