Definitions

• the subject of the invention is an electric power generating solar roof tile which is covered with solar cells on its outer surface.
• the solar cells are equipped with conductors and connectors.
• Further object of the invention is the production process of the power generating solar roof tile.
• the solar roof tile can be installed into a roof cladding consisting of roof tiles of any shape. It fits exactly in place of the existing tile. It follows the surface and design of the existing tile.
• the solar roof tiles can be used for solar roofing, facades and building paneling.
• Hungarian patent specification No. HU 209 222 on equipment utilizing solar power by solar cells is worth mentioning.
• This patent specification describes a specific arrangement of interconnected solar cells on a support structure.
• the solar cells made from foil strips or sheets create a solar panel complex and are fitted in a frameless support.
• the solar panel complex features a trough shaped channel for cooling and for diverting power.
• Another Hungarian patent specification under publication number P9901088 introduces a solar panel roof whose overlapped roof components with the built-in solar cells are connected by a bituminous composite material.
• the solar cells feature extremely thin glass sheets and are in a configuration that ' prevents other roof components from overlapping them.
• Both solar cell inventions described above involve incorporation in an existing roof structure, therefore, they are distinct from the solar cell roof tile subject to the invention.
• JP2001342725 likewise refers to the incorporation of planar solar cells in a roof structure, at the same time exemplifying an embodiment of a solution where solar cells featuring a protective coating of organic resin are strengthened by ribs in order to eliminate the effects of wind pressure.
• the roof structure featured in publication document No. US6065256 and Japanese publication document No. JP 10018514 is suitable for cooling roofs fitted with solar cells and heating them in the winter in order to melt snow, with the provision that air ducts have been incorporated therein.
• the utility model No. DE 299 15 196 U features flat or specially formed solid, pan- shaped roofing materials containing solar cells, each of which contain a large quantity of solar cells on a thick substrate.
• any roof sections containing solar cells consisting of planar sheets must be separately sealed in a waterproof fashion from every direction when fitted. This renders their implementation complicated and costly.
• German publication document No. DE 44 08 508 describes a solution that addresses the above-mentioned criteria for roof tiles.
• This invention solves the problem by fashioning a roof tile whose bottom, top and side edges are identical in design to the original roof tile.
• tiles can be incorporated in a tiled roof, in place of normal roof tiles, without the need for additional seals.
• the planar solar cells are only integrated into the central, flat portion of the roof tile so the entire roof surface does not participate in generating electric power, only a portion thereof.
• our objective is to create a solar cell roof tile and a process for its production in accordance with our invention whereby it is possible to fashion roof tiles that are not only partly but completely identical in shape, form and color, and bear a solar cell layer on their entire outer surface. Therefore, if someone wishes to implement a solar cell roof, they can do so without disrupting the original roof structure or overall appearance thereof, simply by substituting the original roof tiles with the solar cell roof tiles subject to our invention.
• the subject of the present invention is an electric power generating solar roof tile which is covered with solar cells on its outer surface.
• the solar cells are equipped with wires and connectors and it is designed to be fitted in place of any kind of roof tile.
• the essence of the solar cell roof tile subject to our invention is that it possesses a substrate made from plastic or synthetic resin formed into the appropriate shape and size with a flexible solar cell layer containing solar cells applied to the outer surface of the substrate, there are conductive rails and connectors in and/or on the surface of the substrate, furthermore the solar cell layer is either directly or via a conductive stud connected to the conductive rails, and the solar cell layer is sealed in a waterproof manner by a transparent protective layer that tightly conforms to the shape of the outer surface of the roof tile fitted with solar cells.
• the unit subject to the invention is implemented as described in Claim 1.
• the individual examples of embodiment can be implemented according to Claims 2-9.
• the essence of the process used to production of the solar cell roof tile subject to our invention is that a negative form or template of the substrate in the form and size intended to be manufactured or used is prepared then the conductive rails and electric connectors are either placed in the negative form or space is left for them to be installed later.
• a recess is prepared depending on the type of roof tile for the controller electronics and battery to be installed later then the substrate is produced by pressing, casting or injection molding the chosen plastic material into the negative form.
• a flexible solar cell layer is applied to both the flat and convex surfaces of the solidified substrate, the solar cell layer is electrically coupled at the appropriate points to the conductive rails and connectors then the substrate fitted with the solar cell layer is covered by a transparent weather, heat and frost resistant layer that protects the tile from mechanical damage and closely fits to the substrate.
