Ungayikhetha njani iFilimu ye-EVA efanelekileyo kwiSolar Cell Encapsulation?

Ukusebenza kakuhle kunye nobomi bemodyuli yelanga kuxhomekeke kakhulu kumgangatho we-encapsulation yayo. Nangona iiseli ze-photovoltaic ziyinjini yephaneli yelanga, ifilimu ye-EVA (Ethylene Vinyl Acetate) sisikhuselo esiqinisekisa ukusebenza kwexesha elide phantsi kweemeko ezinzima zendalo. Ukukhetha okuchanekileyoIfilimu ye-EVAukuyaukuze uyihlanganise iiseli zelangasisigqibo esibalulekileyo kubaphathi bokuthenga kunye nabavelisi beemodyuli abajolise ekwandiseni i-ROI kunye nokunciphisa ukusilela kwentsimi.

Esi sikhokelo sibanzi sichaza iinkcukacha zobugcisa, imilinganiselo yokusebenza, kunye namaqhinga okuthenga afunekayo ukuze kukhethwe ifilimu ye-EVA efanelekileyo kumgca wakho wemveliso.

Isishwankathelo esifutshane: Iimpawu eziphambili zokuvavanya ifilimu ye-EVA ye-Encapsulate

Kwiinjini zokukhangela kunye nesalathiso esikhawulezileyo, nazi iinkcukacha ezingaxoxiswana ngazo ekufuneka uzijonge xa ​​ufuna ifilimu ye-EVA yeephaneli zelanga:

• Ukuhanjiswa kokukhanya:Kufuneka ibe ngaphezulu kwama-91% ukuqinisekisa ukuba ukukhanya kwelanga okuphezulu kufikelela kwiiseli zelanga.

• Umxholo weGel (Ukudibanisa okunqamlezileyo):Uluhlu olufanelekileyo yi-75% ukuya kwi-85% yokuqina kwesakhiwo kunye nobude bexesha.

• Amandla okuKhuhla:Ubuncinane yi-40 N/cm (eglasini) kunye ne-30 N/cm (ephepheni elingasemva) ukuthintela ukuqhekeka.

• Ukuncipha kobushushu:Kufuneka ihlale ingaphantsi kwe-2% ukuze kuthintelwe ukufuduka kweeseli ngexesha lenkqubo yokulamina.

• Ukumelana nomthamo:Ukumelana okuphezulu kuyafuneka ukuze kuthintelwe ukubola okubangelwa kukubangela iingxaki (i-PID).

Kutheni iFilimu ye-EVA efanelekileyo ibalulekile kwiiseli zelanga

Ngexesha lenkqubo yokwenziwa kweemodyuli zelanga, iiseli zelanga zibekwe phakathi kweengqimba zefilimu ye-EVA, umphambili weglasi, kunye nephepha elingasemva elikhuselayo. Nje ukuba ifudunyezwe kwi-vacuum laminator, i-EVA iyanyibilika, idibane, kwaye iphiliswe, idale ibhloko engangeni manzi, neyomeleleyo ngokwesakhiwo.

Ukusebenzisa ifilimu ye-EVA engaphantsi komgangatho kukhokelela kwimiphumo emibi yezemali kunye nodumo kubavelisi beemodyuli, kubandakanya ukonakala kwamandla ngokukhawuleza, ukuba tyheli, kunye nokungena komswakama. Ukufakwa kwefilimu ekumgangatho ophezulu kuchaphazela ngokuthe ngqo ukungabi namali kweemveliso zakho zelanga zeTier-1.

Ixabiso Lokwenyani Lokugquma Okubi

Idatha yokwenziwa kwemveliso evela kwizityalo zokuhlanganisa ezingama-500MW+ zakutshanje ibonisa ukuba nangona ifilimu ye-EVA ixabisa ngaphantsi kwe-5% yexabiso lilonke lezinto zephaneli yelanga, inoxanduva lokusilela kwentsimi okungaphezulu kwe-40% kwinqanaba lokuqala ukuba ichaziwe ngokuchanekileyo. Ukutyala imali kwiifilimu ze-EVA zeprimiyamu kunciphisa kakhulu amabango ewaranti kunye neendleko ze-O&M (Operations and Maintenance) kumsebenzisi wokugqibela.

Izinto Ezibalulekileyo Xa Ukhetha Ifilimu ye-EVA

Ukuqinisekisa ukuba iimodyuli zakho zelanga zifikelela kubomi bokusebenza beminyaka engama-25 ukuya kwengama-30, jonga ababoneleli be-EVA abanokubakho xa kuthelekiswa nezi parameter zobugcisa.

1. Ukuhanjiswa kokukhanya okuphezulu

Umsebenzi ophambili wefilimu ye-EVA engaphambili kukuvumela ukukhanya kudlule ngaphandle kokuphazamiseka. I-EVA eqhelekileyo inika malunga ne-90% yokudlulisa. Nangona kunjalo, iifilimu ze-EVA ezinokudlulisa okuphezulu (ezidlula i-91.5%) zinyusa ukubanjwa kwe-photon kweeseli zelanga, zinyusa ngokuthe ngqo amandla emodyuli ukuya kuthi ga kwi-1-2 Watts kwiphaneli nganye.

2. Umxholo weGel kunye noxinano oludibanisayo

Xa ifilimu ye-EVA ishushu, kwenzeka i-chemical reaction (cross-linking) eyiguqula ukusuka kwi-thermoplastic ukuya kwi-thermoset material.

• Iphantsi kakhulu (<70%):Ifilimu ihlala ithambile, ibeka emngciphekweni ukuqhekeka, ukungena komswakama, kunye nokuqhekeka kobushushu obuphezulu bokusebenza.

• Iphezulu kakhulu (>85%):Ifilimu iba buthathaka kakhulu, nto leyo eyonyusa umngcipheko woxinzelelo loomatshini kunye nokuqhekeka kweeseli ngexesha leemeko zemozulu ezimbi kakhulu.

3. Iimpawu ze-Anti-PID

Ukonakala okubangelwa kukubangela ingxolo (i-PID) yeyona nto inzima kakhulu kubasebenzi beefama zelanga, ekwaziyo ukunciphisa amandla emodyuli ngama-30% kwiminyaka embalwa nje. I-PID yenzeka ngenxa yokuvuza kwamandla avela kwiiseli zelanga ukuya kwisakhelo semodyuli esisezantsi.Ifilimu ye-Anti-PID EVAngokumelana okuphezulu komthamo kuqinisekisa ukuba umaleko we-encapsulation usebenza njengesigqubuthelo sombane esisebenzayo, ukhusela isivuno samandla sexesha elide somthengi.

4. Ukumelana ne-UV kunye neMozulu

Kwiminyaka engaphezu kwama-25, iphaneli yelanga iya kujongana nemisebe ye-UV enamandla, ukuguquguquka okukhulu kobushushu, kunye nokufuma okuphezulu. Izifunxi ze-UV kunye neziqinisi kufuneka zenziwe ngokufanelekileyo ngaphakathi kwe-resin ye-EVA. Izongezo ezikumgangatho ophantsi zikhokelela ekubeni ifilimu "ibe tyheli" okanye "ibe mdaka", nto leyo ethintela ukukhanya kwelanga kwaye inciphise kakhulu imveliso yamandla.
