Support for photovoltaic panel applied on tiles

Description

Support for photovoltaic panel applied to roof tile. Subject:

[001] This Utility Model Patent refers to a support used for fixing multiple photovoltaic panels for solar energy generation directly onto the tiles of an existing roof. The support is suitable for fixing to the upper portion of the tile, which allows for the best angle for capturing solar rays, increasing the efficiency of energy generation. Furthermore, it is easy and practical to fix, highly durable, and lightweight, making it suitable for installation on the vast majority of existing roofs. State of the Art:

[002] The search for alternatives to generate energy sustainably is constant, due to the needs for environmental preservation and especially to reduce the consumption of fossil fuels.

[003] Although the generation of solar energy through photovoltaic panels is already known in the art, in general their installation on existing roofs requires structural reinforcements through the placement of an extra structure for fixing the panels. This construction requirement sometimes makes installation unfeasible due to technical and / or economic issues, resulting in an unsatisfactory cost-benefit ratio, discouraging the installation of many projects.

[004] As an alternative to the aforementioned extra structure, there are known roof tiles that incorporate an integrated photovoltaic panel. This solution can be seen in document BR 102013004092-4 filed on 02 / 13 / 2013 by SILVA, which describes a photovoltaic energy generating tile, and also in document BR 202012022836-5 filed on 09 / 11 / 2012 by CLARISTONI, which presents a plastic photovoltaic tile, and in both cases it is necessary to remove the Petition 870250103409, dated 12 / 11 / 2025, page 7 / 15 2 / 9 previous roof for the installation of photovoltaic tiles, generating additional costs for its installation.

[005] Document BR 202016019758-4, filed on 8 / 25 / 2016 by the same holder, describes a base made of sustainable polymer with antioxidant, flame retardant and ultraviolet additives, with a shape suitable for installation in the lower portion of the tile, between its high ribs, on which a plurality of photovoltaic panels are installed. In this case, the fixing of the photovoltaic panels is done directly through the polymeric base without the need for any intervention in the tiles, such as drilling or displacement, thus avoiding damage to them.

[006] However, this solution, despite providing easy installation of photovoltaic panels on existing roofs, only uses the area available in the lower sections of the tiles and does not allow the panels to be placed at the best angle for energy generation.

[007] These drawbacks end up being limiting factors for installation on roofs whose tiles have waves with a small low portion or in location situations that do not favor the capture of solar rays. Inventive Concept:

[008] The present Photovoltaic Panel Support Applied on Roof Tile was developed primarily to achieve the following objectives: - to allow the installation of photovoltaic panels from a support placed on the upper portion of the tiles on existing roofs; - to allow all or virtually all of the existing roof area to be used for capturing solar rays; - To allow for better positioning of the photovoltaic panels in relation to the angle of incidence of the sun, increasing efficiency; - Allows for easy and practical installation on a wide variety of roof tile models on existing roofs, whether residential or industrial / commercial; Petition 870250103409, dated 12 / 11 / 2025, page 8 / 15 3 / 9 - Offers high durability due to the support being manufactured from sustainable polymer with antioxidant, ultraviolet, and flame-retardant additives, featuring male and female type fittings with an expansion joint.

[009] To this end, the solution comprises a support whose lower portion has the shape of the high part of the tile wave where the photovoltaic panels are to be installed, and may be curved, trapezoidal or another shape. A straight quadrangular base extends over this lower portion, equipped with internal rails at three of its extremities to allow the photovoltaic panel to be fitted.

[010] The support is manufactured from sustainable polymer with antioxidant, flame-retardant, and ultraviolet additives, which reduce the absorption of heat generated by the tile and which would be transmitted to the photovoltaic panel. The supports have male-type fittings that allow their installation along the length of the tile. They also have expansion joints that allow for easy absorption of the natural expansion and contraction of the tile due to temperature changes without damaging or transmitting this movement to the photovoltaic panels. Although not the preferred construction, the support can alternatively be manufactured from aluminum, which would guarantee the same characteristics regarding lightness, efficiency, and durability.

[011] The panels have a surface layer of tempered glass, preferably self-cleaning glass, colorless or colored, ensuring greater safety for the photovoltaic cells and increasing their durability. Optionally, the tempered glass can be replaced by polymer panels, preferably acrylic panels, colorless or colored.

[012] This solution was designed in this way so that it can be installed on a wide variety of roof tiles on existing roofs, being a practical, efficient and lightweight solution, with the aim of providing use Petition 870250103409, dated 12 / 11 / 2025, page 9 / 15 4 / 9 widespread adoption of this solution, which is very advantageous from an economic point of view and very important from an environmental point of view. Field of Application:

[013] The present Support for Photovoltaic Panels Applied on Roofs is used as a support structure for photovoltaic modules specially adapted for roof structures or roof coverings. Advantages:

[014] The Roof-Mounted Photovoltaic Panel Support offers the following advantages: • It allows for easy installation of photovoltaic panels on existing roofs, thanks to the male and female interlocking systems, without the need to replace the tiles or build an extra structure to support the photovoltaic panels; • Allows installation on various tile styles, eliminating the need for extra supports to fit the panels; • Because the polymer base is made from sustainable polymer with antioxidant, flame-retardant, and ultraviolet additives, it has high durability and a low heat transmission rate; Alternatively, the base can be made of aluminum, guaranteeing the same durability characteristics; • This fact, combined with the fact that the photovoltaic panels are fixed on the upper section of the existing roof tiles, means that less heat from the roof is transmitted to the photovoltaic panels, increasing their efficiency; • For the same reason, there is an increase in the area for capturing solar rays, as well as better positioning with respect to inclination, increasing the efficiency of the system; Petition 870250103409, dated 12 / 11 / 2025, page 10 / 15 5 / 9 • Because the polymer supports have expansion joints, the assemblies expand and contract according to temperature differences without damaging the photovoltaic panels; • It enables the reduction of electricity generation costs and its installation in a wide variety of existing buildings, whether residential, commercial, industrial, or other; • It allows for the widespread installation of modules under a wide variety of technical and economic conditions; • It makes it possible to reduce the use of non-renewable energies, thus reducing carbon emissions generated by burning coal; • Flexibility of use, as the tempered glass, polymer, or acrylic panel used for hail protection can be colorless or colored, matching the colors of the supports and the roof.

Description:

[016] The Photovoltaic Panel Support Applied on Tile consists of a curved base (1) which must have the same shape as the high section of the tile where it will be applied, equipped with side tabs (2) that will serve to place the fixing pins (3) on the tile. Alternatively, fixing by pins (3) can be replaced by fixing with glue or similar material.

[017] Above the curved base (1) there is a straight base (4) which includes a central portion (5) and side rails (6) that are used to attach the photovoltaic panel (7) equipped with a surface layer (8).

[018] The side rails (6) act as drawers that promote easy placement and removal of the photovoltaic panel (7), which also includes the wires (8) for connection between the panels or with the local electrical grid to allow the transmission of energy generated in the panel.

[019] The support is preferably made of polymeric material, preferably PVDF (Polyvinyl Fluoride), containing additives that give it mechanical resistance and protection against UV rays. The intense coloring along with the anti-UV additive makes the pieces also serve as decorative pieces next to the roof, matching its color. The intense colors in a durable way are obtained by adding Petition 870250103409, dated 12 / 11 / 2025, page 12 / 15 7 / 9 concentrated masterbatch type pigment in a proportion of 1% to 5% in thermoplastic resin, whose elements undergo an injection or extrusion process.

[020] In addition, other additives are used to give the floor base strength and durability so that it can be used for a long time exposed to the elements without damaging the circuits and fittings of the photovoltaic panels, such as: - Desiccant additive: absorbs moisture from the polymer, reducing the time during the production process of said object; - Antioxidant additive: protects the polymer against thermo-oxidative degradation during the process; - Flow aid additive: provides increased productivity, reduces and / or eliminates material buildup in the die, and improves the surface characteristics of the object. - Antistatic additive: neutralizes static electricity, preventing dust buildup on the part. - Flame retardant additive: modifies the fire behavior in different polymer mixtures, delays ignition, and reduces the burning rate and smoke formation; - Antimicrobial additive: prevents the proliferation of fungi and bacteria; - Anti-fibrillation additive: helps stabilize the production process; - Expanding agent additives: reduces the weight of the part, aids in thermal and acoustic insulation; - Purging agent additive helps clean machines (injection molding machines, extruders, etc.) saving time and material in production.

[021] The photovoltaic panel (7) comprises one or more photovoltaic cells of type (P) and type (N), comprising a crystalline silicon structure, coated with a conductive film of a dopant solution with natural or synthetic polymers. The type (P) and type (N) dopant solutions comprising components in nanoparticles of Petition 870250103409, dated 12 / 11 / 2025, page 13 / 15 8 / 9 carotenoids such as beta-carotene, canthaxanthin, bixin, norbixin, lycopene, fucoxanthin and others extracted from natural sources such as annatto, tomato, watermelon, guava, corn, carrot, other pumpkins, seaweed and various other natural sources.

[022] Synthetic antioxidant and ultraviolet doping components can also be used, these dopants being used for sun protection causing a decrease in the thermal coefficient and, consequently, an increase in the efficiency of the electrical conductivity of these cells.

[023] The components used in the base composition of photovoltaic cells are crystalline silicon, phosphorus, calcium, rosin resin, cationic fluorocarbon surfactant, liquid glycerin, silver nitrate, crystalline polycarbonate film with ultraviolet filter, or ethylene vinyl acetate polymer (EVA), glass layer or translucent resin with ultraviolet protection additive, in order to provide efficient solar protection for the reduction of the thermal coefficient and, consequently, increase the efficiency in the conductivity of photovoltaic cells. Other formulations may be used in the final composition of encapsulated photovoltaic cells without limiting the invention of other photovoltaic cell products already existing in the world market.

[024] A layer of transparent surface material (8) is fitted over the already encapsulated and integrated photovoltaic cell in the panel (7), enabling the capture of sunlight by the cells. This material contains anti-reflective components, has mechanical resistance against high impacts, is non-stick to prevent excessive dirt accumulation, and is non-slip for safe use.

[025] A possible material to be used, as it encompasses all these characteristics, is self-cleaning tempered glass. For this purpose, this glass receives the incorporation of silica nanoparticles and polymers, generating a protective layer on the glass that confers this characteristic of being self-cleaning, having high transparency and being anti-reflective. The high Petition 870250103409, dated 12 / 11 / 2025, page 14 / 15 The 9 / 9 transparency of this self-cleaning tempered glass improves energy harvesting efficiency by more than 3%.

[026] In some cases there may be male and female type fitting between the photovoltaic panels (7) allowing their linear placement along the tiles, with integrated operation.

[027] The curved base (1) may, alternatively, in a variation, contain a plurality of hollow elements (9) which make the support even lighter and transmit even less heat to the photovoltaic panel (7).

[028] As a variation of the photovoltaic panel fixing, the photovoltaic panel (7) is fixed by screws directly to the flat base (4), using a sealing rubber (10).

[029] The curved base (1) may alternatively assume other tile shapes, such as high and low curves, trapezoidal, trough or other tile models.

[030] In a constructive variant, the support can be formed only by the straight base (4) which includes a central portion (5) and side rails (6) which are used to attach the photovoltaic panel (7) equipped with a surface layer (8), as shown in figures 12 to 14.

[031] In this case, the fixing to the tile is done by screws / rivets or by adhesive product, directly on the flat upper part of the tile, when its shape allows it. Conclusion

[032] Thus, the Photovoltaic Panel Applied on Roof is supported by unprecedented functional characteristics, therefore deserving the legal protection sought.
