" Pannello fotovoltaico perfezionato “ "Improved photovoltaic panel"
La presente invenzione concerne un pannello fotovoltaico perfezionato. È noto che un pannello fotovoltaico è un dispositivo optoelettronico comprendente una matrice di celle fotovoltaiche in grado di convertire l'energia solare incidente in energia elettrica mediante effetto fotovoltaico. The present invention relates to an improved photovoltaic panel. It is known that a photovoltaic panel is an optoelectronic device comprising a matrix of photovoltaic cells capable of converting the incident solar energy into electrical energy by means of the photovoltaic effect.
I pannelli fotovoltaici tradizionali non sono completamente soddisfacenti in quanto risultano piuttosto costosi e complicati da installare, nonché generalmente necessitano di apparecchiature esterne dedicate (ad esempio inverter) che devono essere opportunamente collegate alla rete elettrica. Traditional photovoltaic panels are not completely satisfactory as they are rather expensive and complicated to install, as well as generally require dedicated external equipment (such as inverters) which must be properly connected to the electricity grid.
Ulteriormente, la resa estetica dei pannelli fotovoltaici tradizionali è bassa e, pertanto, la loro diffusione, in particolare nel contesto domestico urbano, è piuttosto limitata. In particolare, attualmente, vi sono delle normative, linee guida e/o regolamenti (generalmente proposte dalle amministrazioni locali) che limitano l’installazione di tali pannelli in zone ad interesse paesaggistico e/o culturale, quali ad esempio centri storici, o in vicinanza di monumenti. Furthermore, the aesthetic performance of traditional photovoltaic panels is low and, therefore, their diffusion, particularly in the urban domestic context, is rather limited. In particular, currently, there are laws, guidelines and / or regulations (generally proposed by local administrations) that limit the installation of such panels in areas of landscape and / or cultural interest, such as historic centers, or in the vicinity of monuments.
Attualmente, i pannelli solari sono installati solamente in posizione verticale o inclinata, generalmente sui tetti, su pareti di edifici o su basi di appoggio, limitando così le possibilità di utilizzo dei pannelli stessi. Currently, solar panels are installed only in a vertical or inclined position, generally on roofs, on the walls of buildings or on support bases, thus limiting the possibilities of using the panels themselves.
Scopo della presente invenzione è di proporre un pannello fotovoltaico perfezionato in grado di risolvere il suddetto inconveniente e che possa essere installato anche in posizione orizzontale o sostanzialmente orizzontale. The object of the present invention is to propose an improved photovoltaic panel capable of solving the aforementioned drawback and which can also be installed in a horizontal or substantially horizontal position.

Altro scopo dell’invenzione è di proporre un pannello che costituisca la soluzione ottimale, in termini di semplicità di realizzazione, per modificare l’aspetto estetico di un tradizionale pannello fotovoltaico. Another purpose of the invention is to propose a panel that constitutes the optimal solution, in terms of simplicity of construction, to change the aesthetic appearance of a traditional photovoltaic panel.
Altro scopo dell’invenzione è di proporre un pannello a basso impatto estetico e/o che comunque possa essere facilmente integrato in un contesto urbano, o nel contesto dell’abitazione o dell’edificio, senza deturpare in alcun modo il territorio circostante. Another purpose of the invention is to propose a panel with a low aesthetic impact and / or that can be easily integrated in an urban context, or in the context of the home or building, without disfiguring the surrounding area in any way.
Altro scopo dell’invenzione è quello di proporre un pannello che possa essere installato anche in zone in cui la normativa o la regolamentazione attuale vietano, per ragioni paesaggistiche, architettoniche o estetiche in generale, l’installazione di pannelli. Another purpose of the invention is to propose a panel that can also be installed in areas where current legislation or regulations prohibit, for landscape, architectural or aesthetic reasons in general, the installation of panels.
Altro scopo dell’invenzione è di proporre un pannello che sia personalizzabile e di aspetto estetico altamente gradevole ed idoneo a fornire all’utilizzatore la sensazione di trovarsi di fronte ad un prodotto di elevata qualità, sia sul piano estetico che funzionale. Another purpose of the invention is to propose a panel that is customizable and has a highly pleasing aesthetic appearance and is suitable for providing the user with the feeling of being in front of a high quality product, both from an aesthetic and functional point of view.
Altro scopo dell’invenzione è quello di proporre un pannello che possa essere utilizzato come pavimentazione. Another purpose of the invention is to propose a panel that can be used as flooring.

Altro scopo dell’invenzione è di proporre un pannello che possa essere sia autonomo ed indipendente dalla rete elettrica nazionale (cioè “off-grid”) o collegato alla rete elettrica (cioè “on-grid”). Another purpose of the invention is to propose a panel that can be autonomous and independent from the national electricity network (ie "off-grid") or connected to the electricity grid (ie "on-grid").
Altro scopo dell’invenzione è di proporre un pannello che possa essere prodotto in serie ed in modo rapido e efficiente. Another purpose of the invention is to propose a panel that can be mass-produced and quickly and efficiently.

Come si vede dalle figure, il pannello fotovoltaico 2 secondo l’invenzione è del tipo destinato ad essere installato in orizzontale, o inclinato rispetto all’orizzontale, in modo da definire un pavimento per esterni o, in generale, un rivestimento di una superficie di calpestio. As can be seen from the figures, the photovoltaic panel 2 according to the invention is of the type intended to be installed horizontally, or inclined with respect to the horizontal, so as to define an outdoor floor or, in general, a covering of a surface of trampling.
Il pannello fotovoltaico 2 comprende una matrice 3 di celle fotovoltaiche 4. The photovoltaic panel 2 comprises a matrix 3 of photovoltaic cells 4.
Preferibilmente, il pannello comprende sostanzialmente sessanta celle fotovoltaiche 4 aventi efficienza di conversione di circa 15-18%. Preferably, the panel comprises substantially sixty photovoltaic cells 4 having conversion efficiency of about 15-18%.
Opportunamente, le celle fotovoltaiche 4 possono essere realizzate in silicio, e preferibilmente in silicio monocristallino. Alternativamente, le celle fotovoltaiche 4 possono essere realizzate in silicio policristallino oppure amorfo oppure CIGS (“Copper Indium Gallium Selenide” i.e. Seleniuro di Indio Gallio e rame) oppure CIS (Copper Indium Selenide, i.e. Seleniuro di indio e rame). Alternativamente, le celle 4 possono essere realizzate a partire da materiali organici, ad esempio a partire da polimeri (ad esempio poli(3,4-etilenediossitiofene):poli(4-stirenesolfonato), PEDOT:PSS) o da molecole (ad esempio ftalocianine o fullereni). Conveniently, the photovoltaic cells 4 can be made of silicon, and preferably of monocrystalline silicon. Alternatively, the photovoltaic cells 4 can be made of polycrystalline or amorphous silicon or CIGS ("Copper Indium Gallium Selenide" i.e. Indium Gallium and copper selenide) or CIS (Copper Indium Selenide, i.e. Indium and copper selenide). Alternatively, the cells 4 can be made starting from organic materials, for example starting from polymers (for example poly (3,4-ethylenedioxythiophene): poly (4-styrenesulfonate), PEDOT: PSS) or from molecules (for example phthalocyanines or fullerenes).
Opportunamente, le celle fotovoltaiche 4 – ed in particolare le loro superfici a vista - possono essere configurate per essere di un colore differente dai tradizionali blu e/o nero, cioè per riflettere principalmente la luce di un determinato colore, che può essere ad esempio grigio metallizzato, verde, violetto, dorato, o rosso mattone. Vantaggiosamente, la colorazione di ciascuna cella 4 può essere ottenuta mediante l’ingegnerizzazione dei vari strati che formano la cella stessa, come ad esempio descritto in EP2154727. Conveniently, the photovoltaic cells 4 - and in particular their visible surfaces - can be configured to be of a different color from the traditional blue and / or black, that is to reflect mainly the light of a certain color, which can be, for example, gray. metallic, green, violet, gold, or brick red. Advantageously, the coloring of each cell 4 can be obtained by engineering the various layers that form the cell itself, as described for example in EP2154727.
Preferibilmente, ciascuna cella 4 comprende uno strato esterno antiriflesso che generalmente è realizzato in SiO2, SiNx, eventualmente addizionato con idrogeno o ZnS. Opportunamente, la cella 4 è configurata in modo da avere un’efficienza finale compresa fra il 15 e il 20%, e preferibilmente fra il 16 e il 19%. Preferably, each cell 4 comprises an external anti-reflective layer which is generally made of SiO2, SiNx, optionally added with hydrogen or ZnS. Conveniently, the cell 4 is configured so as to have a final efficiency between 15 and 20%, and preferably between 16 and 19%.
Le celle fotovoltaiche 4 della matrice 3 sono elettricamente collegate tra loro da nastri di collegamento 6, definiti ribbon, che preferibilmente sono realizzati in rame ricoperto con una lega di stagno. Opportunamente, i nastri di collegamento 6 sono previsti frontalmente sulle celle 4, tuttavia potrebbero essere previsti anche sul retro delle celle stesse, così come previsto dalla tecnologia “back-contact”. The photovoltaic cells 4 of the matrix 3 are electrically connected to each other by connecting tapes 6, defined as ribbons, which are preferably made of copper covered with a tin alloy. Conveniently, the connecting tapes 6 are provided on the front of the cells 4, however they could also be provided on the back of the cells themselves, as envisaged by the "back-contact" technology.
La matrice 3 di celle fotovoltaiche 4 è interposta tra due strati di materiale incapsulante – rispettivamente 8’ (quello frontale/superiore) e 8’’ (quello posteriore/inferiore) - preferibilmente EVA (etilene-vinilacetato). The matrix 3 of photovoltaic cells 4 is interposed between two layers of encapsulating material - respectively 8 '(the front / upper one) and 8' (the rear / lower one) - preferably EVA (ethylene-vinyl acetate).
Allo strato frontale/superiore di materiale incapsulante 8’, è associato almeno un foglio 20 in materiale trasparente e/o traslucido di tipo strutturale e adatto ad essere calpestato (cioè adatto a sopportare il passaggio di una pluralità di soggetti senza danneggiarsi). Preferibilmente, il foglio 20 è in vetro strutturale. Opportunamente, il foglio in materiale trasparente e/o traslucido 20 ha la funzione di proteggere e garantire robustezza all’intero pannello fotovoltaico 2 mantenendo una elevata trasparenza. At the front / upper layer of encapsulating material 8 ', is associated at least a sheet 20 in transparent and / or translucent material of a structural type and suitable for walking on (i.e. suitable for withstanding the passage of a plurality of subjects without being damaged). Preferably, the sheet 20 is made of structural glass. Conveniently, the sheet in transparent and / or translucent material 20 has the function of protecting and guaranteeing strength to the entire photovoltaic panel 2 while maintaining a high transparency.
Preferibilmente, il foglio frontale/superiore 20 è preferibilmente realizzato in vetro solare prismatico ad elevata trasmittanza luminosa, in modo sostanzialmente da non ridurre l’efficienza del pannello fotovoltaico 2. Preferably, the front / top sheet 20 is preferably made of prismatic solar glass with high light transmittance, so as not to substantially reduce the efficiency of the photovoltaic panel 2.
Inoltre, il foglio frontale/superiore 20 è preferibilmente temperato. Opportunamente, il foglio frontale/superiore 20 ha uno spessore di 2-10 mm, e preferibilmente di almeno circa 8-10 mm per garantire le opportune proprietà strutturali. Furthermore, the face / top sheet 20 is preferably tempered. Conveniently, the front / top sheet 20 has a thickness of 2-10 mm, and preferably of at least about 8-10 mm to ensure the appropriate structural properties.
Vantaggiosamente, la superficie captante (che opportunamente è definita dalla faccia esterna 29) del foglio frontale/superiore 20 può essere trattata con un procedimento nanotecnologico che conferisce alla superficie stessa la proprietà di concentrare lo sporco o il calcare, senza limitare la resa del pannello 2 e favorendo la pulizia periodica dello stesso. Advantageously, the capturing surface (which is suitably defined by the external face 29) of the front / top sheet 20 can be treated with a nanotechnological process which gives the surface the property of concentrating dirt or limescale, without limiting the yield of the panel 2 and favoring the periodic cleaning of the same.
Preferibilmente, la faccia esterna 29 del foglio 20 può essere trattata in modo da renderla super-idrofobica, in modo da evitare l’accumulo di acqua, e consentirne lo scorrimento al di fuori della superficie del vetro stesso, consentendo inoltre di rimuovere eventuale sporco e/o calcare dalla superficie del vetro. Opportunamente detti trattamenti possono essere effettuati per via chimica, mediante la deposizione di uno strato super-idrofobico tramite spray coating o mediante deposizione chimica da vapore (in inglese “Chemical Vapor Deposition”), oppure possono essere realizzati per via fisica, ad esempio mediante nano-strutturazione della superficie. Preferably, the external face 29 of the sheet 20 can be treated in such a way as to make it super-hydrophobic, in order to avoid the accumulation of water, and to allow it to slide outside the surface of the glass itself, also allowing to remove any dirt and / or limescale from the glass surface. Conveniently, said treatments can be carried out chemically, by depositing a super-hydrophobic layer by means of spray coating or by chemical vapor deposition (in English "Chemical Vapor Deposition"), or they can be carried out physically, for example by means of nano -structuring of the surface.
Vantaggiosamente, inoltre, la faccia esterna 29 del foglio frontale/superiore 20 può essere trattata con trattamenti antiscivolo oppure può comprende una opportuna texture 60. Opportunamente, detta texture è definita da una pluralità di rilievi e/o incisioni ricavate, preferibilmente chimicamente e permanentemente, sulla faccia esterna 29 di detto foglio. Advantageously, moreover, the external face 29 of the front / top sheet 20 can be treated with anti-slip treatments or it can comprise a suitable texture 60.

Opportunamente, le strisce colorate sono definite sul foglio frontale 20 in modo sostanzialmente corrispondente, dal punto di vista dimensionale, di forma e posizione, ai nastri di collegamento 6 tra le celle fotovoltaiche 4. In sostanza, coprendo i nastri di collegamento 6 mediante decorazioni 24 del foglio di vetro frontale 20 aventi il medesimo colore delle celle 4, si ottiene sul pannello 2 l’effetto complessivo di una base piena ed omogenea di un unico colore (cioè quello delle celle). Alternatively and / or in addition to the above, the decorations 24 of the front glass sheet 20 are positioned and configured in such a way as to cover and / or obscure the connecting tapes 6 between the photovoltaic cells 4. In particular, for this purpose, the decorations 24 comprise colored and / or decorated sections / strips obtained on the front glass sheet 20 and of a color substantially corresponding to that of the photovoltaic cells 4 or another desired color. Conveniently, the colored strips are defined on the front sheet 20 in a substantially corresponding way, from the dimensional point of view, in shape and position, to the connecting tapes 6 between the photovoltaic cells 4.

Il funzionamento del pannello fotovoltaico 2 secondo l’invenzione risulta chiaramente da quanto descritto. In particolare, la matrice 3 di celle fotovoltaiche 4 trasforma, mediante effetto fotovoltaico, la luce solare incidente in corrente continua che poi, attraverso il regolatore di carica 14, viene stoccata nell’unità di accumulo 13 oppure viene inviata direttamente all’inverter che la trasforma in corrente alternata per l’autoconsumo immediato da parte di un’utenza esterna al pannello stesso. The operation of the photovoltaic panel 2 according to the invention is clear from what has been described. In particular, the matrix 3 of photovoltaic cells 4 transforms, by means of a photovoltaic effect, the incident sunlight into direct current which then, through the charge controller 14, is stored in the storage unit 13 or is sent directly to the inverter which transforms into alternating current for immediate self-consumption by a user external to the panel itself.
Vantaggiosamente, l’energia elettrica generata nel pannello stesso e stoccata nell’unità di accumulo 13 può venire utilizzata per alimentare i mezzi luminosi associati ed integrati nel pannello stesso. Vantaggiosamente, l’energia elettrica generata nel pannello stesso viene utilizzata, senza essere stoccata nell’unità di accumulo 13, per alimentare direttamente i mezzi luminosi 40 associati ed integrati nel pannello stesso. Advantageously, the electricity generated in the panel itself and stored in the storage unit 13 can be used to power the associated and integrated lighting means in the panel itself. Advantageously, the electricity generated in the panel itself is used, without being stored in the storage unit 13, to directly power the luminous means 40 associated and integrated into the panel itself.
Alternativamente, almeno una parte dell’energia elettrica prodotta dal pannello 2 può essere immessa in rete mediante il cavo elettrico 16. Alternatively, at least part of the electricity produced by the panel 2 can be fed into the network through the electric cable 16.
È altresì inteso che, in una forma di realizzazione alternativa del pannello 2 secondo l’invenzione, questo possa essere privo di mezzi di collegamento ad un’utenza e che l’energia elettrica generata dalla matrice 3 di celle fotovoltaiche 4, eventualmente stoccata nell’unità di accumulo 13, possa essere utilizzata esclusivamente per l’alimentazione dei mezzi luminosi previsti nel pannello stesso. In particolare, in tale circostanza, il pannello 2 ha solamente una funzione ornamentale e/o di illuminazione dell’ambiente o zona di installazione, cioè senza alcuna funzione di approvvigionamento energetico alle utenze. It is also understood that, in an alternative embodiment of the panel 2 according to the invention, this can be devoid of means for connecting to a user and that the electrical energy generated by the matrix 3 of photovoltaic cells 4, possibly stored in the storage unit 13, can be used exclusively for powering the luminous means provided in the panel itself. In particular, in this circumstance, the panel 2 has only an ornamental and / or lighting function of the environment or installation area, that is, without any function of energy supply to the users.

- può essere facilmente e rapidamente collegabile mediante la sua presa di uscita alla rete elettrica domestica, - it can be easily and quickly connected to the home electrical network via its output socket,
- presenta eccellenti caratteristiche di praticità d’uso ed installazione dato che può essere posizionato sia verticalmente che inclinato, - it has excellent features of ease of use and installation since it can be positioned both vertically and tilted,
- è indipendente e compatto dato che tutti i suoi componenti sono opportunamente integrati all’interno dell’ingombro in pianta dello stesso, - richiede uno spazio di installazione ridotto e non necessita di apparecchiature esterne, e - it is independent and compact given that all its components are suitably integrated within the overall footprint of the same, - it requires a small installation space and does not require external equipment, and
- è flessibile, modulare e scalabile a seconda delle necessità. - it is flexible, modular and scalable as needed.
In particolare, il pannello secondo l’invenzione risulta particolarmente vantaggioso in quanto è utilizzabile per definire una struttura a pavimento o un rivestimento adatto ad essere calpestato, consentendo così di ampliare le possibilità ed i contesti per la sua installazione. In particular, the panel according to the invention is particularly advantageous as it can be used to define a floor structure or a covering suitable for walking on, thus allowing to expand the possibilities and contexts for its installation.
La presente invenzione è stata illustrata in alcune sue preferite forme di realizzazione, ma si intende che varianti esecutive potranno ad esse in pratica apportarsi, senza peraltro uscire dall'ambito di protezione del presente brevetto per invenzione industriale. The present invention has been illustrated in some of its preferred embodiments, but it is understood that executive variations may apply thereto in practice, without however departing from the scope of protection of the present patent for industrial invention.
