Definitions
- the invention relates to a photovoltaic element according to the preamble of the first claim.
- Similar photovoltaic elements are well known and are mostly used for application to a flat roof. Here are usually several photovoltaic elements welded together with their geomembranes side by side, so that the sum of the welded photovoltaic elements in addition to the power generation function also simultaneously fulfills the function of a roof seal.
- the single-layer systems are additionally differentiated according to the type of cabling:
- the single-layer system in which the connection of the photovoltaic modules to the wiring from below, whereby the sealing sheet is pierced.
- the wiring itself is inserted into the thermal insulation layer of the roof.
- the advantage is a low risk of damage to the contact points when walking the roof and it is not necessary to protect the contact points with mechanical covers.
- only one geomembrane layer is necessary.
- the disadvantage is the frequent penetration of the sealing level in the flat roof area.
- the core of the invention is therefore that the contact points of the photovoltaic module arranged on the side facing the geomembrane are and the means for electrical connection pierced the geomembrane.
- An advantageous embodiment of the photovoltaic element provides that the means for electrical connection to the contact points puncture the sealing web twice.
- an advantageous embodiment of the photovoltaic element provides that the means for the electrical connection of the contact points between the sealing web
- Punctured contact points twice preferably also the means for electrical connection to the contact point on the photovoltaic module
- an additional cover sheet along the fürstossembl applied in particular welded and / or glued, in the area of the fürstossembl of the geomembrane on the underside of the geomembrane, which is preferably made of plastic, in particular of the same material as the geomembrane itself, should exist.
- the additional cover sheet should run in its longitudinal direction along the fürstossus.
- a particularly secure variant with respect to the sealing security is achieved, however, if a shaped piece is arranged in the region of the cover web, which creates an air-permeable connection to a cavity formed by cover web and sealing web. As a result, the tightness of the system can be detected by means of a vacuum test.
- the fitting is connected to the geomembrane or even better on the underside of the geomembrane, in particular welded and / or glued. If such a shaped piece is used, this can additionally be used particularly advantageously for at least one electrical connection or all electrical connections to pass through this fitting to the outside. As a result, possible additional leakage points are avoided.
- a further advantageous embodiment provides that the means for electrical connection have plug connections, so that a simple wiring is possible.
- Range of contact points 3 shows an oblique view of a partially rolled-out photovoltaic element; 4: unrolled photovoltaic element with four photovoltaic modules; 5 shows a cross section through a photovoltaic element in the region of
- FIG. 6 shows a cross section through a photovoltaic element with cover sheet in the region of the contact points
- FIG. 7 shows a cross section through a photovoltaic element with connection grommet for the
- FIG. 1 illustrates a photovoltaic element 1 according to the invention with a photovoltaic module 2.1 mounted on one side of the geomembrane.
- the contact points 4.1 and 4.2 of the photovoltaic module 2.1 are arranged on the side facing the waterproofing membrane 8 and the means for electrical connection 6.1 or 6.2 pierces the sealing membrane 8.
- the contact points 4.1, 4.2 each lead out the positive or negative polarity of the respective photovoltaic module.
- the means attached to the respective contact points 4.1, 4.2 means for electrical connection 6.1, or 6.2, can be used to connect the photovoltaic element 1 with other photovoltaic elements in series or in parallel.
- the geomembrane attached to the contact points 4.1, 4.2 means for electrical connection 6.1, or 6.2, the geomembrane also pierced together at the same place.
- the photovoltaic modules may be connected to each other in series or in parallel, with the advantage of a higher voltage in the case of a serial connection, resulting in a higher current in the parallel connection.
- FIG. 2 the photovoltaic element 1 from FIG. 1 is depicted, wherein it can be seen that a cover sheet 5 is applied, in particular adhesively bonded and / or welded, to the underside of the sealing sheet 8, thereby ensuring in a secure manner the permanent sealing of Roofs with the help of photovoltaic elements 1 offers.
- FIG. 3 shows a photovoltaic element 1 according to the invention in a partly rolled-up state, consisting of a sealing sheet 8, on which four photovoltaic modules 2.1 to 2.4 are fixed and which has a common plug connection 3 for an external power connection.
- FIG. 4 shows such a photovoltaic element from FIG. 3 in an unrolled state, with the illustration of the invention in the left Area at the individual photovoltaic modules 2.1 to 2.4 contact points 4.1, 4.2 can be seen, each leading out the positive or negative polarity of the respective photovoltaic module and where means for electrical connection to the contact points 6.1, or 6.2, are attached.
- These contact points 4.1, 4.2 are mounted on the underside of the photovoltaic modules 2.1 to 2.4 so that they point in the direction of the underlying geomembrane 8. At these contact points 4.1 and
- Terminals in the serial connection row of the photovoltaic modules 2.1 to 2.4 are each a means for electrical connection 6.1 or 6.2 connected to the contact point, which pierces the sealing sheet 8 immediately behind the contact point and on the side on which the entire electrical connection of the photovoltaic element 1 is, where they once again pierced the waterproofing membrane 8 from below.
- Terminals in the serial connection row of the photovoltaic modules 2.1 to 2.4 are each a means for electrical connection 6.1 or 6.2 connected to the contact point, which pierces the sealing sheet 8 immediately behind the contact point and on the side on which the entire electrical connection of the photovoltaic element 1 is, where they once again pierced the waterproofing membrane 8 from below.
- cover sheet 5 is located on the underside of the waterproofing membrane again a cover sheet 5, which encloses this entire area and waterproof covers.
- the cover sheet 5 is connected to the sealing sheet 8, in particular adhesively bonded and / or welded, so that there is a secure sealing situation.
- FIG. 6 shows the photovoltaic element 1 from FIG. 5, wherein it can be seen that the cover web 5 is located on the lower side of FIG
- Sealing web 8 applied, in particular glued and / or welded, and thereby provides a secure way of guaranteeing a permanent sealing of roofs using the photovoltaic elements 1.
- a further improvement of the invention can be achieved in that - as shown in Figure 7 - additionally a connector grommet 9 attached to the geomembrane 8 in the region of the formed by the geomembrane 8 and the underlying, in particular glued and / or welded, cover sheet 5 cavity formed is.
- this connector grommet which may be formed, for example, flexible and rigid and can be welded as a fitting to the sealing sheet 8, by vacuuming air 10, a vacuum in the space 11, between the geomembrane 8 and the cover sheet 5, are generated.
- the tightness can be checked in accordance with an optionally measurable pressure drop, so that the tightness of the entire system of the photovoltaic element 1 is ensured with high reliability.
- connection sleeve can also be used to lead the means for electrical connection 6.1, or 6.2, to the outside, as shown in Figure 8. This measure avoids possible leaks due to further breakthroughs.
- an air connection must then be used, which allows the plug 3 to be included at short notice, or the connections to the plug have to be made later, so that only the means for electrical connection 6.1 and 6.2 are to be accommodated in the air connection.
