Solar tiles for generating hot water

It is common knowledge that thermal solar systems can be installed on the roofs of buildings to generate hot water. There are basically two ways to install solar collectors: a) the collectors can be mounted on the existing roof tiles or concrete roof tiles (hard roofing) using appropriate brackets and devices, or b) they can be installed directly into the roof instead. The installation option under a) incurs considerable costs due to the complex installation and higher follow-up costs for repairs. In addition, this type of installation does not allow for good visual integration into the respective roof. Although the optical aspect is better solved with the installation option under b), here too a visually satisfactory solution is not possible due to the different sizes of solar collectors and the respective roof tiles or concrete roof tiles. In addition, the transitions from the solar collectors to the aforementioned hard roofing must be particularly sealed, as there is no compatibility between the two. Since in both cases the commercially available solar panels are significantly larger than individual roof tiles or concrete roof tiles, damage results in greater financial expenses.

The invention specified in the claims is based on the problem of eliminating the disadvantages of the solar systems currently available on the market, as outlined above.

This problem is solved by the features listed in the claims.

The use of solar goats, as described in the claims, instead of conventional solar collectors results in the following advantages:

1. Due to complete compatibility with the commercially available variants of the aforementioned hard roofing, installation is easier to accomplish and significantly cheaper.

2. When repairing, only individual solar tiles need to be replaced, which is easy to do as they can be hung in and out like normal roof tiles or concrete roof tiles.

3. In addition to the reduced workload and the resulting cost savings, the visual impression of solar systems is significantly improved.

4. When installing for the first time or when subsequently expanding, the consumer or owner has greater design options with regard to the surface area of the system.

An advantageous embodiment of the invention is to produce the substructure and frame of the solar tile from polyurethane foam or a similar material suitable for insulation (additional insulation).

An embodiment of the invention is shown in the drawing and is described in more detail below.

Fig. 1 an absorber (1) made of copper or other suitable absorber material with water inlet (2) and outlet (3).

Fig.2 the collector tank made of polyurethane foam or a similar material suitable for insulation. The shape of the collector tank is such that it resembles the profile of the aforementioned hard roofing, so that it can be installed in the roof instead of a roof tile or concrete roof tile and takes over the functions of the aforementioned hard roofing, such as water drainage and sealing. On the top of the collector tank there is a corresponding recess (4) to accommodate the absorber (1). There is a passage (5) at the top of the collector tank (insulation) (6) for the absorber inlet (2). On the opposite side there is a larger cutout through which the absorber drain pipe (3) leads.
Fig.3 the collector tank (6) with built-in absorber (1).

Fig.4 the connection of two collectors. The two pipe ends are connected by a heat, cold and UV-ray resistant and, if possible, flexible connection (preferably a plug connection) to enable the exchange of individual collectors.
The collector is closed at the top by a glass plate (7) with the same properties as standard collector systems (temperature and weather resistance, as little reflection as possible, etc.). The glass plate extends about ten centimeters beyond the lower edge of the solar tile. This creates an overlap with the collector below and thus ensures safe water drainage.

Claims (1)

The protection claims relate to thermal solar collectors for the production of hot water.
The further development of the currently known solar collectors is characterized by the fact that a) the individual solar panels are the size of standard roof shingles and b) are designed in such a way that they are compatible with the existing roof tiles or concrete roof tiles and can therefore be installed in the roof instead of them.
