Definitions
- the invention relates to a solar module with one or more solar cells, which are arranged parallel to the module surface between a transparent windshield and a base member, wherein the windscreen and the base member are made of glass and sealed at the edge regions to each other.
- Solar or PV modules of the type mentioned are individually or in groups installed and interconnected, used in photovoltaic systems for centralized and decentralized power generation.
- the individual solar module is intended to meet a variety of requirements at the various sites, in particular, the solar cells arranged inside or solar panels to be protected from the weather and mechanical stress. Furthermore, the solar module should protect the electrical connections against moisture and diffusion and provide for a corresponding electrical insulation to the outside.
- the PV module consists essentially of a two-pane insulating glass, wherein the two panes are spaced apart at the edge by a hollow profile and form a gap in which the solar cells are arranged. Outwardly, the insulating glass element is sealed in a known manner with an elastic sealant, the electrical connection lines are led out the edge.
- the individual solar cells are fixed by soldering on the inside of at least one of the glass panes. The sunlight enters through the windscreen and interacts with the solar cells inside the insulating glass pane.
- the windscreen may have an outer and / or inner coating, which should improve the efficiency of the module.
- No. 6,693,237 A describes a PV module in which the solar cells are integrated into a layer structure and the outer layers of the housing can also be made of glass. - -
- a common feature of the embodiments mentioned above is that a frame or an edge region is required for sealing the housing, consisting of an outer glass pane and a planar base element, which may also be made of glass, which forms a shading area, particularly in the case of oblique incidence of light has a negative effect on the overall efficiency of the solar module.
- the edge region of the solar module which is available for sealing measures, however, can not be made arbitrarily narrow, otherwise due to the occurring temperature stresses during operation and the mechanical influences (wind, snow load, etc) can not be guaranteed sufficient tightness for years of operation.
- a solar module which has a supporting structure made of metal or synthetic resin, which can be bent along a row of holes to form a fold on the edge. It is thereby formed a basic structure with edge fold, in which a solar cell with a transparent front foil can be inserted.
- a layered structure of a solar module is known from EP 0 829 909 A2, wherein in one of the embodiments a basic structure made of a metal or plastic layer is shown, which is bent over at the edges to form a fold extending substantially at right angles from the module front side.
- the solar cell is covered by a filler and covered by a front, transparent layer, which is attached to the outer fold.
- bent to the module front fold results in the juxtaposition of multiple solar modules, a relatively large unused area between the individual solar cells, whereby the efficiency of the arrangement is impaired.
- the folded in the direction of the module front fold results in the formation of shadows in obliquely incident solar radiation.
- the solar cells are embedded in a housing, wherein the encapsulation may consist of glass or hardenable casting polymers and films.
- a container is attached, which is completely filled with a cooling medium.
- the solar module is arranged like a lid on the container with the cooling medium, wherein the container is part of a cooling circuit, which comprises a pump and a cooling device.
- the object of the invention is therefore, starting from known solar modules to propose improvements with which the overall efficiency of the solar module can be increased, with cost-effective to manufacture, robust, wit- - solar resistant solar modules are to be sought, which are used worldwide - especially in the sunbelt around the equator.
- the edge regions of the windshield and the base member are bent or angled to a substantially perpendicular projecting from the module rear fold and form a filled with a sealing or potting compound gap to each other.
- the responsible for the tightness of the module edge region from the plane of the solar cell is bent backwards, whereby a substantially rectangular projecting glass fold is formed, which is available in sufficient folding width for sealing measures, without on the front of the solar module for adverse shading to care.
- a frameless glass solar module is created on the front side, whereby radiation is also applied to the peripheral solar cells in the event of oblique incidence of light.
- the fold improves the mechanical properties of the module and can be optimally used for fastening purposes.
- the falt length or depth can be adapted to the desired requirements, such as service life or dielectric strength.
- a solar module in which the front pane with its bent edge regions comprises the base element with its bent or angled edge region in the manner of a pot.
- the two edge regions of the front pane and of the base element have latching elements on their outer surfaces which interact with corresponding latching elements of clip-on profile or frame elements.
- both the front glass and the base element made of glass, so that a frameless from the front view glass-only solar module is created, which is universally applicable and is optimally protected against the weather.
- the rearwardly projecting fold from the edge regions of the front and base disk simultaneously serves as a mechanical stiffening of the solar module and can be used optimally for fastening individual solar modules to a substructure.
- the base member may have substantially parallel coolant channels for guiding a coolant flow, which are integrated to cool the solar cells entirely in the glass body of the base member.
- the direct integration of parallel and / or zigzag-shaped and / or meander-shaped coolant channels into the base disk or the base element of the solar module leads to a - - Effective, uniform cooling of the solar cells, whereby the efficiency of the solar module can be significantly increased.
- the base element consists of two glass panes arranged in parallel, which are connected to one another by webs between the coolant passages running substantially parallel.
- the two glass panes of flat and / or pressed glass can first be produced with integrally formed web elements, which are then connected to one another by welding or fusing the web elements together.
- Such all-glass versions are particularly suitable for solar systems in the offshore sector.
- the base element on the side facing the solar cells as a flat and / or pressed glass pane with integrally formed web elements which are sealed by means of a flat cover element, so that substantially parallel coolant channels are formed between the web elements.
