In one preferred embodiment, the roof component has a shape of a plurality of roof tiles, arranged in rows and / or columns and superimposed on each other, for solar rays. And at least one solar cell is provided on one side of the rigid plate, which in use is located on a bottom surface of the roof tile plate.

An advantage of this configuration is that the at least one solar cell is protected from external weather effects by a transparent rigid plate. This makes the roof component particularly reliable, while further extending the life of the at least one solar cell.

[0010] In the specific embodiment, preferably, the at least one solar cell is manufactured from a flexible sheet-like material. In particular, said at least one solar cell is adhered to said rigid plate. However, other wedge methods are possible.

In one particular embodiment of the invention, in use as roof covering in combination with other roof components, only a portion of the rigid plate that is not covered by the other roof components is the at least One solar cell can be provided.

[0012] The advantage achieved in this way is that only those parts of the roof component which are exposed to light during use and thus process electrical energy are provided with the at least one solar cell. It is to be possible.

In particular, the roof component is further provided with an electrical terminal clamp for supplying electrical energy generated by the at least one solar cell.

The roof component may have a standard dimension of, for example, 1.1 mx 8.4 m. Generally, the roof component has a surface area greater than 2 m ² . However, it is also possible for only one roof component to have dimensions as required to form a roof cover.

[0015] In one highly preferred embodiment, the roof component further comprises at least one fluid flow path for heating the fluid with solar energy, wherein the fluid comprises:
In use as roof covering, it flows through the flow channel.

In this way, both electrical and thermal energy can be generated.

The solar cell 4 is fitted into each of the openings. In contrast to the previous embodiment, the solar cell 4 does not consist of a sheet-like flexible material. It is not necessary, because the solar cell 4 can in this case have a thickness that is greater, equal or less than the thickness of the rigid plate 6. However, each solar cell 4 has the shape of a roof tile. Therefore, the solar cells 4 are likewise arranged in rows and / or columns, overlapping one another. Each solar cell 4 is provided with an electric terminal clamp 16 and an electric connection wire 20. The solar cells 4 can be electrically interconnected before fitting the roof tile plate on the roof, for example, in a factory, in series or in parallel or a combination thereof.

At least one or all layers can also include at least copper indium diselenide (CIS for short). Various manufacturing methods are also possible. Furthermore, it is also possible to apply a layer on the roof component that allows for a stronger and better distributed light incident on the solar cell. If various roof components are used to assemble the roof covering, the solar cells of these roof components can be connected in parallel and / or in series. Of course, one method consists in storing the electrical energy remaining in the battery and / or returning it to the electrical grid. The solar cell 4 can be arranged below, above or inside the rigid plate. As shown in FIG. 4, it is also possible for the transparent covering material 40 to be fitted onto the solar cell 8 in a way that the solar cell is fitted into the structural shape of FIGS. This material can consist, for example, of a hard or soft plastic. Glass may be used. The solar cell 8 is in fact included in this case in a rigid plate, which is indicated in FIG. 4 by the reference numerals 6 and 40. Similarly, the fluid channels 30 can be located below, above, or in the rigid plate 6. It is also possible to connect these fluid flow paths of the various roof components to one another. Further, the solar cell 4 can be arranged below or above the fluid flow path. In addition, an insulated collector can be mounted in or below the rigid plate, which eliminates the need for a separate storage container. This collector is built into a rigid plate. Furthermore, other methods for generating thermal energy are possible. The roof components can be easily joined together. One example of these roof elements that can be joined together on a roof is, for example, a number of regular roof tiles and a flexible provided with a lock and hook system or an adhesive edge.
