Description
IDROPROTEZIONE PER ELEMENTI FOTOVOLTAICI HYDROPROTECTION FOR PHOTOVOLTAIC ELEMENTS
La presente invenzione si riferisce ad un'idroprotezione per elementi fotovoltaici. The present invention refers to a hydroprotection for photovoltaic elements.
Sono già noti nella tecnica pannelli fotovoltaici di tipo rigido. Alcune rare soluzioni prevedono invece una forma di pannelli fotovoltaici di tipo flessibile, i quali pannelli tuttavia presentano l'inconveniente di avere una bassa efficienza, essendo realizzati in silice amorfa. Dato che i pannelli con alta efficienza attuali presentano celle fotovoltaiche in silice monocristallina e policristallina estremamente fragili ed indeformabili in condizioni normali, risulta in pratica impossibile abbinare queste celle ad un pannello flessibile che possa essere adattato a svariati tipi di applicazioni che lo richiedono. Rigid photovoltaic panels are already known in the art. Some rare solutions provide instead a form of photovoltaic panels of the flexible type, which panels however have the drawback of having a low efficiency, being made of amorphous silica. Given that the current high efficiency panels have photovoltaic cells in monocrystalline and polycrystalline silica that are extremely fragile and non-deformable under normal conditions, it is practically impossible to combine these cells with a flexible panel that can be adapted to various types of applications that require it.
Inoltre, i pannelli flessibili esistenti sono soggetti ad infiltrazioni di acqua ed altri liquidi e risultano scarsamente impermeabili ad essi; infine, questo tipo di pannello risulta difficile da ancorare su supporto rigido o deformabile, e da interconnettere con altri pannelli adiacenti, affinchà ̈ possa superare la certificazione CEI EN61215. Furthermore, the existing flexible panels are subject to infiltration of water and other liquids and are scarcely impermeable to them; finally, this type of panel is difficult to anchor on a rigid or deformable support, and to interconnect with other adjacent panels, so that it can pass the CEI EN61215 certification.
Scopo della presente invenzione à ̈ quello di risolvere i suddetti problemi della tecnica anteriore fornendo un'idroprotezione per elementi fotovoltaici in grado di realizzare un pannello flessibile con celle cristalline applicabile anche alle applicazioni edilizie, in grado, cioà ̈, di superare le prove richieste dalla certificazione CEI EN61215. The purpose of the present invention is to solve the aforementioned problems of the prior art by providing a hydroprotection for photovoltaic elements capable of realizing a flexible panel with crystalline cells also applicable to building applications, capable of passing the tests required by CEI EN61215 certification.
Questa idroprotezione presenta inoltre la caratteristica di protezione del panello dalle infiltrazioni di acqua e altri liquidi, ed impedisce la permeabilità dell'incollante all'acqua, oltre ad agevolarne l'ancoraggio eventuale su un supporto rigido o deformabile e l'interconnessione con altri pannelli adiacenti. This hydroprotection also has the characteristic of protecting the panel from the infiltration of water and other liquids, and prevents the permeability of the glue to water, as well as facilitating its possible anchoring on a rigid or deformable support and interconnection with other adjacent panels. .
Con il pannello sopra indicato, risulta pertanto possibile estendere l'applicabilità dei generatori fotovoltaici in settori in cui à ̈ necessario avere elevata efficienza su piccole superfici con pesi ridotti, come ad esempio nel settore automobilistico, aeronautico, nautico e camperistico ed edilizio, in cui la portata del tetto o la forma richiedano queste condizioni. With the panel indicated above, it is therefore possible to extend the applicability of photovoltaic generators in sectors where it is necessary to have high efficiency on small surfaces with reduced weights, such as in the automotive, aeronautical, nautical and camper and construction sectors, in which the span of the roof or the shape require these conditions.
I suddetti ed altri scopi e vantaggi dell’invenzione, quali risulteranno dal seguito della descrizione, vengono raggiunti con un'idroprotezione per elementi fotovoltaici come quella descritta nella rivendicazione 1. Forme di realizzazione preferite e varianti non banali della presente invenzione formano l’oggetto delle rivendicazioni dipendenti. The above and other objects and advantages of the invention, as will emerge from the following description, are achieved with a hydroprotection for photovoltaic elements such as that described in claim 1. Preferred embodiments and non-trivial variants of the present invention form the subject of dependent claims.
La presente invenzione verrà meglio descritta da alcune forme preferite di realizzazione, fornite a titolo esemplificativo e non limitativo, con riferimento ai disegni allegati, nei quali l'unica Figura 1 à ̈ una vista in sezione laterale parziale di una forma di realizzazione della presente invenzione. The present invention will be better described by some preferred embodiments, provided by way of non-limiting example, with reference to the attached drawings, in which the only Figure 1 is a partial side sectional view of an embodiment of the present invention .
Facendo riferimento alla Figura, à ̈ illustrata e descritta una forma di realizzazione preferita dell'idroprotezione della presente invenzione. Risulterà immediatamente ovvio che si potranno apportare all'idroprotezione descritta innumerevoli varianti e modifiche (per esempio relative a forma, dimensioni, disposizioni e parti con funzionalità equivalenti) senza discostarsi dal campo di protezione dell'invenzione come appare dalle rivendicazioni allegate. Referring to the Figure, a preferred embodiment of the hydroprotection of the present invention is illustrated and described. It will be immediately obvious that innumerable variations and modifications (for example relating to shape, dimensions, arrangements and parts with equivalent functionality) can be made to the described hydroprotection without departing from the scope of the invention as appears from the attached claims.
Come illustrato, l'idroprotezione inventiva si applica a pannelli fotovoltaici flessibili, che sono costituiti da: As illustrated, inventive hydroprotection applies to flexible photovoltaic panels, which consist of:
- una pluralità di celle o elementi fotovoltaici 3 disposti affiancati ed elettricamente connessi; - a plurality of photovoltaic cells or elements 3 arranged side by side and electrically connected;
- almeno uno strato 2 di pellicola di polimero avente proprietà incollanti ed incapsulanti delle celle o elementi fotovoltaici 3 per tenerli incollati tra loro a formare il pannello con gli altri strati; - at least one layer 2 of polymer film having bonding and encapsulating properties of the photovoltaic cells or elements 3 to keep them glued together to form the panel with the other layers;
- almeno uno strato 4, 5 di pellicola di polimero avente proprietà protettive, posto intorno allo strato 2 avente proprietà incollanti; e - at least one layer 4, 5 of polymer film having protective properties, placed around the layer 2 having gluing properties; And
- almeno uno strato 1 di pellicola di polimero avente proprietà fotoselettive, sovrapposto ad almeno uno strato 4, 5 di pellicola di polimero avente proprietà protettive. - at least one layer 1 of polymer film having photoselective properties, superimposed on at least one layer 4, 5 of polymer film having protective properties.
L'idroprotezione à ̈ costituita da almeno un cordone sigillante 6 contornante l'intero perimetro del pannello fotovoltaico applicabile anche mediante termosaldatura. The hydroprotection consists of at least one sealing cord 6 surrounding the entire perimeter of the photovoltaic panel which can also be applied by heat sealing.
Tale cordone sigillante 6 potrebbe, in alternativa, essere anche dotato di almeno un elemento di ancoraggio 7 accoppiato operativamente ad almeno un lato del cordone sigillante 6 stesso, e che circonda e riveste completamente il cordone 6, come si vede bene dalla Figura. Said sealing bead 6 could, alternatively, also be equipped with at least one anchoring element 7 operatively coupled to at least one side of the sealing bead 6 itself, and which completely surrounds and covers the bead 6, as can be clearly seen from the Figure.
Come ulteriore alternativa, il cordone sigillante 6 potrebbe essere sostituito completamente da almeno un elemento di ancoraggio 7 contornante l'intero perimetro del pannello fotovoltaico (come si deduce dalla Figura eliminando il cordone sigillante 6). As a further alternative, the sealing bead 6 could be completely replaced by at least one anchoring element 7 surrounding the entire perimeter of the photovoltaic panel (as can be deduced from the Figure by eliminating the sealing bead 6).
L'elemento di ancoraggio 7, per le varianti dell'idroprotezione sopra indicate, può essere realizzato in materiale flessibile oppure rigido. The anchoring element 7, for the variants of hydroprotection indicated above, can be made of flexible or rigid material.
Tale cordone sigillante 6 e/o elemento di ancoraggio 7 à ̈ atto a proteggere le celle 3 dalle infiltrazioni di liquidi vari, e ad impedire la permeabilità dell'incollante all'acqua, oltre che ad agevolare il loro l'ancoraggio eventuale su un supporto rigido o deformabile, e la loro interconnessione con altri gruppi/pannelli adiacenti. Said sealing cord 6 and / or anchoring element 7 is designed to protect the cells 3 from the infiltration of various liquids, and to prevent the permeability of the glue to water, as well as to facilitate their possible anchoring on a support. rigid or deformable, and their interconnection with other adjacent groups / panels.
Sono state illustrate e descritte in precedenza alcune forme di realizzazione preferite della presente invenzione: ovviamente, agli esperti nel ramo risulteranno immediatamente evidenti numerose varianti e modifiche, funzionalmente equivalenti alle precedenti, che ricadono nel campo di protezione dell'invenzione come evidenziato nelle rivendicazioni allegate. Some preferred embodiments of the present invention have been illustrated and described above: obviously, numerous variants and modifications, functionally equivalent to the previous ones, which fall within the scope of the invention as highlighted in the attached claims, will be immediately apparent to those skilled in the art.
