DESCRIZIONE DESCRIPTION
Il pannello fotovoltaico in plexiglass (polimetilmetacrilato PMMA) è costituito da due pannelli in plexiglass, le proprietà tecniche di suddetto materiale sono molteplici, esso risulta essere più trasparente del vetro, è leggerissimo, infatti pesa la metà di una lastra di- vetro, è termoisolante per oltre il 40% e ha la proprietà di smaltire il calóre accumulato alle proprie estremità laterali, resiste agli agenti atmosferici, è infrangibile 15 volte più di una lastra di vetro, è riciclabile, a seconda delle miscele è antigraffio e resistente quasi totalmente ai raggi UV. può essere lucidato con appositi strumenti e si deforma a una temperatura di circa 130°C. The plexiglass photovoltaic panel (PMMA polymethylmethacrylate) consists of two plexiglass panels, the technical properties of the aforementioned material are manifold, it is more transparent than glass, it is very light, in fact it weighs half of a glass plate, it is heat insulating for over 40% and has the property of disposing of the heat accumulated at its lateral ends, it resists atmospheric agents, is unbreakable 15 times more than a sheet of glass, is recyclable, depending on the mixes it is scratchproof and almost totally resistant to rays UV. it can be polished with special tools and deforms at a temperature of about 130 ° C.
La lastra superiore trasparentissima (FIG. 1 A) serve da protezione dagli agenti atmosferici quali grandine, pioggia, raggi UV e deve essere a bassa trasmissione termica con una ottima filtrazione della luminosità pari al 92% . Il suo spessore può variare dai 2-5 mm, per una maggiore protezione della trasparenza può essere applicata una patina antigraffio. The very transparent upper sheet (FIG. 1 A) serves as protection from atmospheric agents such as hail, rain, UV rays and must have low thermal transmission with excellent filtration of brightness equal to 92%. Its thickness can vary from 2-5 mm, for a greater protection of transparency an anti-scratch patina can be applied.
La lastra inferiore (FIG. 1B) è anch’essa trasparente, con spessore 4-5 mm e serve per l’alloggiamento delle celle al silicio, non necessita di particolari altre proprietà chimiche tranne la sua bassa trasmissione termica. The lower plate (FIG. 1B) is also transparent, with a thickness of 4-5 mm and is used for housing the silicon cells, it does not require any particular chemical properties except its low thermal transmission.
Il montaggio dei componenti viene fatto sulla lastra in plexiglass sottostante, questo per facilitare l’eventuale sostituzione della lastra anteriore. The assembly of the components is done on the underlying plexiglass plate, this to facilitate the possible replacement of the front plate.
I distanziatori (FIG. 1E-2A) mantengono separate le due lastre di plexiglass, hanno spessore 1 mm sono in plexiglass trasparente, questi proteggono le celle al silicio da eventuali urti. Vengono incollati sul pannello sottostante e vanno a formare Γ alloggiamento delle celle e circondano la fila in serie di celle, essi hanno la doppia funzione sia di mantenere le celle in posizione e servono a contenere anche le strisce di ribbon necessarie per ì collegamenti elettrici che passano al disotto di essi. The spacers (FIG. 1E-2A) keep the two plexiglass plates separate, they are 1 mm thick and are made of transparent plexiglass, these protect the silicon cells from any impacts. They are glued to the underlying panel and form a cell housing and surround the series row of cells, they have the dual function of both keeping the cells in position and also containing the ribbon strips necessary for the electrical connections that pass through below them.
La colla è di tipo mono o bicomponente apposita per plexiglass che scioglie le due superfici da incollare. lasciando un sottile strato di polimero che determina l’incollaggio. The glue is of the single or two-component type suitable for plexiglass that dissolves the two surfaces to be glued. leaving a thin layer of polymer that determines the bonding.
Alle celle al silicio mono o policristallino (FIG. 1F-2D) dopo l’alloggiamento viene applicata in genere una lastra ultrasottile di film termoplastico di tipo PUR (poliuretano monocomponente reattivo all’umidità) oppure con APAO-R (palialfaolefine amorfe reattive) che fonde a una temperatura di circa 60°C e salda il tutto con la lastra inferiore in plexiglas e isola completamente le celle, in questo modo nulla può essere sostituito per manutenzione o altro. Nel caso di questo progetto ogni cella viene trattata singolarmente a spray creando su di esse una patina ultrasottile trasparente e altamente idrorepellente anti UV, questo materiale mantiene le sue caratteristiche fino a una temperatura di 180°C .in questo modo le celle vengono distaccate dalle lastre in plexiglas per non creare assorbimento di calore per contatto, hanno la possibilità inoltre di una facile sostituzione .(questa soluzione da la possibilità di eseguire riparazioni a distanza di tempo per successive manutenzioni), nei test effettuati in caso di penombra la cella trattatacon spray-risulta rendere il 4-6 % in piu rispetto ad una cella non trattata, anche con forte irraggiamento si hanno ottimi risultati . To the mono or polycrystalline silicon cells (FIG.1F-2D) after the housing an ultra-thin sheet of thermoplastic film of PUR type (one-component polyurethane reactive to humidity) or with APAO-R (reactive amorphous palialphaolefins) is generally applied which it melts at a temperature of about 60 ° C and welds everything with the lower Plexiglas plate and completely isolates the cells, in this way nothing can be replaced for maintenance or other purposes. In the case of this project, each cell is treated individually by spray, creating on them an ultra-thin transparent and highly water-repellent anti-UV patina, this material maintains its characteristics up to a temperature of 180 ° C. In this way the cells are detached from the plates in Plexiglas in order not to create heat absorption by contact, they also have the possibility of easy replacement. (this solution gives the possibility to carry out repairs after some time for subsequent maintenance). results in 4-6% more yield than an untreated cell, excellent results are obtained even with strong irradiation.
La guarnizione siliconica (FIG 1C-2B) ha uno strato adesivo che ne facilita il posizionamento lungo il perimetro della lastra, nel momento della compressione ha la proprietà di scendere di spessore passando da 5mm a soltanto Imm. The silicone gasket (FIG 1C-2B) has an adhesive layer that facilitates its positioning along the perimeter of the plate, at the moment of compression it has the property of decreasing in thickness, passing from 5mm to only Imm.
Il sistema viene chiuso a incastro meccanico (FIG. 1) senza utilizzo di siliconi o colle e tramite profilati in alluminio (FIG. 1D). Le due lastre in plexiglass insieme alla guarnizione al loro interno vanno compresse il loro spessore deve risultare altezza complessiva H (FIG. IH) uguale all’altezza della cavità del profilato in alluminio I ( FIG li) in cui andranno ad inserirsi. Tutte le lastre di alluminio vengono unite nel retro tramite staffe ad L (FIG 3A-4A) con viti filettate (FIG. 3B). The system is closed by mechanical interlocking (FIG. 1) without the use of silicones or glues and by means of aluminum profiles (FIG. 1D). The two plexiglass plates together with the gasket inside them must be compressed, their thickness must be the overall height H (FIG. IH) equal to the height of the cavity of the aluminum profile I (FIG li) in which they will be inserted. All the aluminum plates are joined at the back by means of L-shaped brackets (FIG 3A-4A) with threaded screws (FIG. 3B).
I cavi elettrici (FIG. 2E) fuoriescono in basso al pannello (FIG. 2C) prima della guarnizione forando il vetro plexiglass posteriore per evitare il passaggio della corrente elettrica vicino all’alluminio, e vanno direttamente nella scatola di derivazione (FIG. 4B), collegando all’ interno un diodo di protezione per evitare cariche elettriche inverse. The electrical cables (FIG.2E) come out at the bottom of the panel (FIG.2C) before the gasket, piercing the rear plexiglass glass to prevent the passage of electric current near the aluminum, and go directly into the junction box (FIG.4B) , by connecting a protection diode inside to avoid reverse electric charges.
L’utilità di tale sistema riguardano in particolar modo l’isolamento termico delle celle al silicio, la chiusura ermetica e la migliore trasparenza del Plexiglass. Il progetto potrebbe essere testato con sistema di invecchiamento artificiale per garantirne durata nel tempo. The usefulness of this system concerns in particular the thermal insulation of the silicon cells, the hermetic closure and the better transparency of the Plexiglass. The project could be tested with an artificial aging system to ensure its duration over time.
