The system is placed on the surface of the panel exposed to the solar radiation, in a fixed or removable manner.

Description

QUASAR ù COVERING SYSTEM ON THERMAL SOLAR PANELS TO REDUCE VISUAL IMPACT TO ZERO

The present invention relates to a system for reducing the visual impact of solar panels on the ambient environment in which they are installed. More specifically, the invention relates to a cover system for the mimicry of solar panels with the surrounding environment.

The invention fits, in particular, in the sector of the use of solar energy for the production of domestic hot water, a sector in constant growth, especially in the countries of the Mediterranean zone, thanks to the climatic conditions but also in countries with adverse environmental conditions that have long encouraged these green energy systems through a policy of tax concessions and benefits. As is known, the installation of solar thermal panels for the production of domestic hot water requires the occupation of sufficiently large areas located in areas in which the solar radiation is optimal with a consequent visual impact and important on the environment .

For this reason, in areas classified in special categories of municipal development plans (for example, historic centers or sites of historical and / or natural interest), very restrictive standards are in place to impose many constraints. and limitations in installing these new green technologies.

At the same time, a large number of people, even outside these areas subject to regulatory constraints and restrictions, do not always appreciate the installation of solar panels (for example, on roofs and / or terraces) that inevitably disfigure the architectural harmony of the building on which they are installed or integrate poorly with the surrounding environment and structures.

It therefore seems obvious that such problems end up discouraging the diffusion and exploitation of solar installations for the production of domestic hot water; this same policy of tax concessions and benefits intended to stimulate the use of such alternative and ecological energy systems risks being invalidated or at least slowed down.

An object of the present invention is to eliminate at least some of the problems set forth above. In particular, an object of the present invention is to provide means for reducing the visual impact on the surrounding environment following the installation of solar panels for the conversion of solar radiation into thermal energy. Another object of the present invention is to stimulate and allow the use and diffusion of ecological energy installations even in urban and natural areas subject to restrictive regulatory constraints for their installation, as, by way of non-exhaustive example, historic centers, sites of architectural interest and landscape. For this purpose, the invention proposes a cover system for the mimicry of a solar panel with the surrounding medium, characterized in that the image of the surrounding medium in which said solar panel is installed is reproduced on it, said cover system being capable of being placed, fixed or removable, on the surface of said solar panel exposed to solar radiation. These and other objects, which will emerge more clearly later, are advantageously achieved with a system which furthermore comprises at least one of the following features: said solar panel is an exposed solar thermal panel or said solar panel is a glazed thermal solar panel; a fabric provided with holes of dimensions such as to allow effective irradiation of said surface exposed to solar radiation without compromising visibility and the interpretation of said reproduced image, - the system is semi-transparent to the incident solar radiation, - said covering system: - is fixed, and - coincides with the glazed surface exposed to the solar radiation of said glazed thermal solar panel, the image the surrounding environment, naturally semi-transparent and / or perforated, thus being reproduced directly on said glass surface.

Other features of the present invention will emerge more clearly from the following description of certain preferred embodiments, and illustrated, solely by way of illustration and without limitation, in the accompanying drawings, in which: FIG. 1 schematically represents a view in perspective of the solar panel according to the invention and the structure on which it is installed. Hereinafter, the features of the invention are described using the reference numerals shown in the figures. With reference to FIG. 1, the reference numeral 1 indicates, as a whole and by way of non-exhaustive example, a glazed thermal solar panel of known type and therefore comprising: a glazed upper surface 11, exposed to solar radiation, who lets in the one who arrives and blocks the one who goes out; an underlying absorbent plate, not shown, which makes it possible to absorb the radiation and to transfer the energy collected to the coolant (usually an antifreeze fluid, for example propylene glycol); - Channels (not shown) in thermal contact with said absorbing plate, in which flows the heat transfer fluid subjected to a warming; a thermal insulation material for all the parts not exposed to solar radiation and a possible outer envelope to protect the aforementioned components and to limit the thermal dispersions of the panel (both not shown). With reference to the nonlimiting example of FIG. 1, said solar panel 1 is connected through a hydraulic circuit, of which is represented only the outlet duct 12 and the inlet 13 of the heat transfer fluid, to an accumulation tank for users for sanitary water and for ambient heating. According to the example of FIG. 1, the circulation of the heat transfer fluid which transports the heat energy captured in the solar panel 1 to the storage tank is of the forced type, that is to say carried out, as is known. by means of one or more pumps (not shown); nothing prevents however that said circulation is of the "natural" type. According to the invention, it is mounted with techniques and means known on said solar panel 1, in correspondence of its glass surface 11, a cover system 2 on which is reproduced, by screen printing and / or printed the ambient environment in which the panel 1 is intended to be installed (the reproduced image can be obtained for example from a digital photo taken on site before the installation of the solar panel 1 and representing, by way of non-limiting example, the panel of a roof, the surrounding landscape, the balustrade of a terrace and / or a fence, etc.). More specifically, said cover system 2, which, as will be illustrated, may be fixed or removable, is preferably a fabric (or film) made of any material adapted for this purpose, in particular resistant to atmospheric agents, which has holes 21 of dimensions such that they allow the passage of solar radiation to the underlying glass surface 11 without compromising the visibility and interpretation of what is represented. The inevitable decrease in the production of electrical energy by the solar panel absorbing plate 1, due to the partial coverage caused by the perforated roofing system 2, may be compensated, in the design phase and, where appropriate, by the addition of a greater number of solar panels 1. For purely illustrative purposes and without any intention of limitation, as represented in FIG. 1, on the cover system 2, the object of the invention, are reproduced, screen printed and / or printed tiles 31 roof 3 on which the solar panel 1 is to be placed, so as to allow its effective mimicry with it and a consequent reduction in its visual impact. It is obvious that for the person skilled in the art, numerous variants of the device forming the subject of the invention are possible without departing from the innovation framework inherent in the inventive idea, just as it is clear that, in the practical implementation of the invention, the various components previously described may be replaced by technically equivalent elements. Nothing prevents, for example, that said cover system 2, instead of being positioned on glazed solar panels for the production of domestic hot water, can be used also on solar panels discovered.

In addition, the mimetic cover system 2 can be: - opaque but necessarily removable (for more details, see for example the Italian patent AN2007A000046 in the name of the same applicant) - or fixed, but which then necessarily leaves to pass a part incident light because it is - semi-transparent, or - - provided with an adequate perforation 21 (as already widely described) - or removable, but which lets pass some of the incident solar radiation. Alternatively, the image of the surrounding environment surrounding the solar panel 1, instead of being reproduced by screen printing and / or printed on a perforated screen 2, can be reproduced, with known techniques and methods, directly on the glass surface 11 and naturally semi-transparent solar panel 1 (of course in the case of a solar panel 1 glazed). It is evident that with the cover system 2 for solar panels for the production of domestic hot water, the aforementioned aims are achieved, in particular the possibility of extending the use of said solar panels 1 also in all areas (historic centers, urban areas adjacent to sites of historical and / or natural interest, etc.) where the constraints and standards do not permit their installation, following the reduction of their visual impact.
