DOCUMENTO 'DESCRIZIONE' MODIFICATO Domanda per Brevetto Per Invenzione avente Titolo: " Procedura di accoppiamento moduli fotovoltaici di tipo flessibile a membrana impermeabile e prodotto così ottenuto" DOCUMENT 'DESCRIPTION' MODIFIED Application for Patent For Invention with Title: "Procedure for coupling photovoltaic modules of flexible type with waterproof membrane and product thus obtained"

La presente invenzione riguarda una procedura di accoppiamento di moduli fotovoltaici flessibili con membrane impermeabili. L'impiego di membrane impermeabili prefabbricate rappresenta uno dei sistemi più diffusi in Edilizia per la realizzazione dell' Elemento di Tenuta Continuo. Uno dei prodotti più affidabili e tecnologicamente evoluti, abitualmente adottato per la realizzazione dell'Elemento di Tenuta Continuo sulle coperture, à ̈ la membrana prefabbricata in TPO (ThermoplasticsPolyOlefins), FPO (FlexiblePolyOlefins), a base di lega di Poliolefine flessibili modificate. Questo prodotto à ̈ particolarmente indicato e largamente diffuso per la realizzazione di pacchetti di copertura in fabbricati civili ed industriali di grandi dimensioni con manto a vista, idoneo per impianti fotovoltaici. La tipologia di impianto fotovoltaico con moduli flessibili aderenti al manto di copertura si integra architettonicamente con l'edificio e riduce i carichi gravanti sulla struttura. Tale sistema viene impiegato in abbinamento ai moduli fotovoltaici innovativi con totale integrazione architettonica e sostituisce i tradizionali metodi di realizzazione delle coperture. L'abbinamento tra moduli fotovoltaici innovativi flessibili e la membrana impermeabile richiede una particolare tecnica realizzativa e deve garantire una affidabile resistenza e durata nelle condizioni di impiego più impegnative, in ogni situazione ambientale, contrastando efficacemente azione del vento e l'aggressione degli agenti atmosferici. I moduli fotovoltaici flessibili, così come sono forniti dal produttore, non sono in grado di garantire da soli una adeguata tenuta impermeabile della copertura dove vengono applicati, necessitano pertanto di una idonea procedura di accoppiamento con le membrane impermeabili. La procedura di accoppiamento e fissaggio dei moduli fotovoltaici flessibili sul manto di copertura attualmente più diffuso à ̈ quello di incollaggio dell'estradosso dei moduli (substrato) sull'estradosso del manto come da già nota membrana di copertura per l'impermeabilizzazione di un edificio per la protezione contro le intemperie con pannelli so descritta da brevetto DE19828462. L'impiego di adesivi per questo incollaggio non offre adeguate garanzie di durata nel tempo, e presenta molte incognite per la certificazione del sistema. L'esposizione alle intemperie ed alle severe condizioni ambientali, nonché agli impegnativi sbalzi termici, ne riducono notevolmente l'aspettativa di vita e l'affidabilità, obbligando a costosi ed indesiderati interventi di manutenzione .Lo scopo della presente invenzione à ̈ pertanto quello di implementare una procedura di accoppiamento tra i moduli fotovoltaici flessibili e le membrane impermeabili prefabbricate in lega di poliolefine flessibili modificate TPO/FPO, di rapida ed affidabile esecuzione, che garantisca nel tempo ed in tutte le condizioni climatiche di esercizio la sua funzionalità, senza intaccare le prestazioni di tenuta impermeabile del manto di copertura. La procedura della presente invenzione permette di effettuare la saldatura dei moduli direttamente sui sito di installazione e non pre-fabbricati in stabilimento e di posizionare i moduli senza interspazi. Con l'accoppiamento a regola d'arte del modulo fotovoltaico flessibile alla membrana impermeabile si realizza un sistema unico in grado di generare energia elettrica mediante processo fotovoltaico e di garantire la tenuta all'acqua meteorica, nonché di resistere efficacemente a tutte le aggressioni degli agenti atmosferici. Questo sistema à ̈ in grado di sostituire le tradizionali metodologie di rivestimento delle coperture sugli edifici, diventandone parte integrante. Questa invenzione à ̈ dunque relativa ad una procedura, come definito nell' allegata Rivendicazione 1, per la saldatura dell'intradosso (fondo) di moduli fotovoltaici flessibili a membrane impermeabili prefabbricate in lega di poliolefine flessibili modificate TPO/FPO. L'invenzione prevede inoltre l'utilizzo della procedura definita in Rivendicazione 1 per la realizzazione di moduli fotovoltaici non convenzionali innovativi che estendono le caratteristiche dei moduli fotovoltaici flessibili originali modificandone il substrato, in modo da ottenere un sistema di copertura ed impermeabilizzazione comprendente una superficie fotovoltaica attiva, un substrato impermeabile ed una metodologia per la realizzazione dello stesso che sostituisce i tradizionali sistemi di rivestimento delle coperture degli edifici, diventando parte integrante della copertura stessa, come definito nell' allegata Rivendicazione 3. Altri vantaggi, caratteristiche e modalità di impiego della presente invenzione risulteranno evidenti dalla seguente descrizione dettagliata di alcune metodologie di realizzazione, presentate a scopo esemplificativo e non limitativo. Gli esempi sono corredati da alcuni disegni di riferimento allegati. The present invention relates to a procedure for coupling flexible photovoltaic modules with waterproof membranes. The use of prefabricated waterproof membranes represents one of the most widespread systems in Construction for the construction of the Continuous Sealing Element. One of the most reliable and technologically advanced products, usually adopted for the construction of the Continuous Sealing Element on roofs, is the prefabricated membrane in TPO (ThermoplasticsPolyOlefins), FPO (FlexiblePolyOlefins), based on a modified flexible Polyolefin alloy. This product is particularly suitable and widely used for the construction of roofing packages in large civil and industrial buildings with exposed covering, suitable for photovoltaic systems. The type of photovoltaic system with flexible modules adhering to the roofing integrates architecturally with the building and reduces the loads on the structure. This system is used in combination with innovative photovoltaic modules with total architectural integration and replaces the traditional methods of roof construction. The combination of innovative flexible photovoltaic modules and the waterproof membrane requires a particular construction technique and must guarantee reliable resistance and durability in the most demanding conditions of use, in any environmental situation, effectively counteracting the action of the wind and the aggression of atmospheric agents. The flexible photovoltaic modules, as supplied by the manufacturer, are not able to guarantee by themselves an adequate waterproof seal of the roof where they are applied, therefore they require a suitable coupling procedure with the waterproof membranes. The procedure for coupling and fixing the flexible photovoltaic modules on the currently most common roofing mantle is that of gluing the extrados of the modules (substrate) on the extrados of the mantle as already known as roof membrane for waterproofing a building for the protection against bad weather with panels is described by patent DE19828462. The use of adhesives for this bonding does not offer adequate guarantees of duration over time, and presents many unknowns for the certification of the system. Exposure to bad weather and severe environmental conditions, as well as to demanding temperature changes, considerably reduce life expectancy and reliability, forcing expensive and unwanted maintenance interventions. The purpose of the present invention is therefore to implement a coupling procedure between the flexible photovoltaic modules and the prefabricated waterproof membranes in TPO / FPO modified flexible polyolefin alloy, of rapid and reliable execution, which guarantees its functionality over time and in all operating climatic conditions, without affecting the waterproof sealing performance of the roof covering. The procedure of the present invention allows to carry out the welding of the modules directly on the installation site and not pre-manufactured in the factory and to position the modules without gaps. With the state-of-the-art coupling of the flexible photovoltaic module to the waterproof membrane, a unique system is created that is able to generate electricity by means of a photovoltaic process and to guarantee resistance to meteoric water, as well as to effectively resist all the aggressions of weathering. This system is able to replace the traditional methods of covering the roofs on buildings, becoming an integral part of it. This invention therefore relates to a procedure, as defined in the attached Claim 1, for welding the intrados (bottom) of flexible photovoltaic modules to prefabricated waterproof membranes in TPO / FPO modified flexible polyolefin alloy. The invention also provides for the use of the procedure defined in Claim 1 for the production of innovative non-conventional photovoltaic modules which extend the characteristics of the original flexible photovoltaic modules by modifying the substrate, so as to obtain a roofing and waterproofing system comprising a photovoltaic surface active, a waterproof substrate and a methodology for its realization that replaces the traditional systems of covering the roofs of buildings, becoming an integral part of the roof itself, as defined in the attached Claim 3. Other advantages, characteristics and methods of use of this invention will be evident from the following detailed description of some manufacturing methodologies, presented by way of non-limiting example. The examples are accompanied by some attached reference drawings.

3 : rivestimento dell'accoppiamento del modulo fotovoltaico flessibile alla membrana impermeabile prefabbricata. Con riferimento alla figura "A", il modulo fotovoltaico flessibile viene indicato con il richiamo (1) e rappresenta un dispositivo attivo in grado di convertire direttamente l'energia solare in energia elettrica mediante effetto fotovoltaico. Il modulo viene fornito in film flessibile, imbustato in una protezione di polietilene. Sulla sua superfice superiore (1.2), il materiale plastico trasparente trasmette le radiazioni solari alle sottostanti celle fotovoltaiche (1.3). Il substrato (1.4), chiude la parte inferiore (intradosso) del modulo fotovoltaico flessibile, sigillando così le celle interno del modulo stesso. Il modulo comprende inoltre un collettore (1.5), al quale sono collegate le celle fotovoltaiche (1.3). Viene identificato un bordo perimetrale (1.6), nel quale non vi à ̈ presenza di celle fotovoltaiche (1.3). Con riferimento alla figura "B" si precisa che una porzione della Membrana impermeabile prefabbricata à ̈ indicata complessivamente con il numero di riferimento (2) e la superfice di estradosso viene indicata con il riferimento (2.1); su questa superfice, identificata con il numero di riferimento (2.2), viene indicata l'area di appoggio, avente dimensioni coincidenti con l'area del substrato (4) del modulo fotovoltaico flessibile (1). In figura "C" si identifica con il numero di riferimento (3) il rivestimento dell'accoppiamento del modulo fotovoltaico flessibile (1) alla membrana impermeabile prefabbricata in lega di poliolefine flessibili modificate TPO/FPO.I moduli fotovoltaici flessibili vengono resi contestualmente solidali al sottostante manto impermeabile, realizzato con membrane impermeabili prefabbricate in lega di poliolefine flessibili modificate TPO/FPO, mediante saldatura superficiale per termo fusione, con insufflazione di aria calda a mezzo di idoneo erogatore in corrispondenza dei bordi perimetrali del modulo fotovoltaico, tra lo stesso e la membrana, previo trattamento mediante acetato di etile delle superfici da accoppiare. L'apparecchiatura impiegata , tipo "VARIMAT 220 V" a controllo elettronico, consente l'accoppiamento delle due superfici con avanzamento automatico e rullino pressore che insiste sulle fasce riscaldate ad aria calda. La velocità di avanzamento à ̈ variabile, in funzione delle condizioni di lavoro e delle temperature esterne ambientali, da cm. 3: coating of the coupling of the flexible photovoltaic module to the prefabricated waterproof membrane. With reference to figure "A", the flexible photovoltaic module is indicated with the reference (1) and represents an active device capable of directly converting solar energy into electrical energy by means of the photovoltaic effect. The module is supplied in flexible film, wrapped in a polyethylene protection. On its upper surface (1.2), the transparent plastic material transmits solar radiation to the underlying photovoltaic cells (1.3). The substrate (1.4) closes the lower part (intrados) of the flexible photovoltaic module, thus sealing the internal cells of the module itself. The module also includes a collector (1.5), to which the photovoltaic cells (1.3) are connected. A perimeter border (1.6) is identified, in which there is no photovoltaic cells (1.3). With reference to figure "B" it is specified that a portion of the prefabricated waterproof membrane is indicated as a whole with the reference number (2) and the extrados surface is indicated with the reference (2.1); on this surface, identified with the reference number (2.2), the support area is indicated, having dimensions coinciding with the substrate area (4) of the flexible photovoltaic module (1). In figure "C" the reference number (3) identifies the coating of the coupling of the flexible photovoltaic module (1) to the prefabricated waterproof membrane in TPO / FPO modified flexible polyolefin alloy. The flexible photovoltaic modules are simultaneously made integral with the underlying waterproof mantle, made with prefabricated waterproof membranes in TPO / FPO modified flexible polyolefin alloy, by surface welding by thermal fusion, with hot air blowing by means of a suitable dispenser at the perimeter edges of the photovoltaic module, between it and the membrane, after treatment with ethyl acetate of the surfaces to be coupled. The equipment used, type "VARIMAT 220 V" with electronic control, allows the coupling of the two surfaces with automatic advancement and a pressure roller that insists on the bands heated by hot air. The speed of advancement is variable, according to the working conditions and the external ambient temperatures, from cm.

150 a cm. 280 al minuto. Le temperature di erogazione aria calda variano, a seconda delle condizioni meteoclimatiche e umidità relativa al momento dell'accoppiamento, da 350 a 470 °C II substrato (intradosso) (1.4), dei modulo fotovoltaico flessibile 1 e l'area di Appoggio (2.2) sulla superfice della membrana impermeabile prefabbricata TPO/FPO, vengono preventivamente trattate con acetato di etile . Il modulo fotovoltaico flessibile (1) viene steso sull'area di appoggio (2.2) della superfice della membrana impermeabile prefabbricata TPO/FPO (2) in modo complanare, per consentire la perfetta adesione del substrato (1.4) su tutta l'area di appoggio (2.2). L'operazione consente di ottenere un perfetto accoppiamento, come si evidenzia nella figura "C", rendendo del tutto solidali i due Elementi, con elevate resistenze alle sollecitazioni dinamiche derivate dall'azione del vento. 150 to cm. 280 per minute. The hot air supply temperatures vary, depending on the meteorological conditions and relative humidity at the time of coupling, from 350 to 470 ° C The substrate (intrados) (1.4), of the flexible photovoltaic module 1 and the support area (2.2 ) on the surface of the prefabricated TPO / FPO waterproof membrane, are previously treated with ethyl acetate. The flexible photovoltaic module (1) is laid on the support area (2.2) of the surface of the prefabricated waterproof membrane TPO / FPO (2) in a coplanar way, to allow perfect adhesion of the substrate (1.4) over the entire support area (2.2). This operation allows to obtain a perfect coupling, as shown in figure "C", making the two elements completely integral, with high resistance to the dynamic stresses deriving from the action of the wind.
