Ventilated Multilayer Solar Panel with Dynamic Digital Filter

Abstract

A ventilated multilayer dynamic digital filter for photovoltaic panels includes a LED front panel, an intermediate panel having a photovoltaic surface, and a rear panel, the panels indirectly overlapping each other so that interspaces are created between the panels which are configured to allow the heat to circulate within the digital filter. Described herein is also the use of the digital filter for exterior cladding of facades and/or roofs of buildings, with the possibility of changing the patterns/textures of the cladding and improving the energy efficiency of a building.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be described in detail below through a preferred embodiment thereof, which is only provided by way of non-limiting example with reference to the annexed drawings, wherein:

[0014] FIG. 1 shows a perspective view of a ventilated multilayer dynamic digital filter for photovoltaic panels according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] With reference to the Figure, the ventilated multilayer dynamic digital filter 10 for photovoltaic panels according to the invention comprises a front panel 11 comprising a LED grid or a series of parallel LEDs, an intermediate panel 12 comprising a photovoltaic surface, and a rear panel 13, said panels 11, 12, 13 indirectly overlapping each other.

[0016] Preferably, the front panel 11 comprises a semi-transparent LED screen that comprises a LED grid or a series of parallel LEDs, the empty spaces in the LED grid or between the series of LEDs being configured to allow the light to pass through the front panel 11, so that it will hit the photovoltaic surface of the intermediate panel 12 without preventing the images reproduced on the front panel 11 from being perceived as full and definite, with a level of semi-transparency and/or transparency comprised between 30% and 95%. In particular, the percentage ratio between the empty spaces and the spaces occupied by the LEDs of the semi-transparent LED screen is preferably comprised between 30% and 95%.

[0017] Preferably, the multilayer dynamic digital filter 10 comprises a frame 21, 22, 23 positioned on the perimeter of each panel 11, 12, 13, the frame 21 of the front panel 11 being in contact with the frame 22 of the intermediate panel 12, which is in turn in contact with the frame 23 of the rear panel 13 so as to create interspaces between the panels, said interspaces being configured to allow the heat to circulate within the multilayer dynamic digital filter 10 in order to prevent both overheating and ice formation; preferably, the frames 21, 22, 23 of the front panel 11 in contact with each other are connected by means of hinges, so that it can be opened like a book in order to inspect the interspaces between the panels 11, 12, 13, e.g., for cleaning and service purposes.

[0018] The front panel 11 may be made of shatterproof transparent material, so as to make the structure of the ventilated multilayer dynamic digital filter 10 strong and resistant to atmospheric events or acts of vandalism, as well as to particularly high loads, e.g., for roof or ground installation. In particular, as far as the building field is concerned, the multilayer dynamic digital filter 10 of the invention may be used for assembling prefabricated houses and for exterior cladding of facades and/or roofs, with the possibility of changing the patterns/textures of the cladding and improving the energy efficiency of a building.

[0019] The ventilated multilayer dynamic digital filter 10 for photovoltaic panels according to the invention offers the following advantages: [0020] the semi-transparent LED screen permits the passage of light, which is transformed into energy by the intermediate photovoltaic panel; [0021] the energy thus produced can be either used for reducing the energy consumption of the screen or stored for other uses; [0022] the LED grid creates a protection for the intermediate photovoltaic panel which, since the panel is hit by UV rays to a lesser extent, will extend the life of the silicon and of the other components of the panel while reducing their temperature, so that the panel will be more efficient in operation; [0023] the air chambers provided in the interspaces reduce the temperature within the structure by dissipating the heat, thereby making the photovoltaic panel more efficient when exposed to the sun and improving the operating conditions of the LED screen while reducing the risk of overheating; [0024] the heat circulating within the interspaces during the cold seasons prevents ice formation and improves the performance of the digital screen by keeping the operating temperature more stable.

[0025] The preferred embodiments of the invention described herein may of course be subject to further modifications and variations without departing from the inventive idea. In particular, it will be immediately apparent to those skilled in the art that numerous functionally equivalent variations and modifications will fall within the protection scope of the invention, as highlighted in the appended claims, wherein any references between brackets should not be understood to limit the claims themselves. Furthermore, the word “comprising” shall not exclude the presence of elements and/or steps other than those listed in the claims. The article “a” or “an” before an element shall not exclude the presence of a plurality of such elements. The simple fact that some features are mentioned in dependent claims shall not imply that a combination of such features cannot be used to advantage.
