Kwintsimi ehlala iguquguquka yamandla elanga, izinto ezisetyenziswa kwiimodyuli ze-photovoltaic zidlala indima ebalulekileyo ekusebenzeni kwazo kunye nobomi. Enye yezinto ezinjalo ezitsala umdla obalulekileyo ziifilimu ezicekethekileyo ze-EVA zelanga, ngakumbi iifilimu ezicwengileyo zelanga ze-EVA ezibonisa elubala. Eli nqaku lijonge ukukukhokela malunga nendlela yokukhetha i-solar efanelekileyoEVA ifilimu encinciukuqinisekisa ukuqina kwexesha elide kunye nokucaca kwizicelo zakho zelanga.
Ukuqonda iifilimu zeSolar EVA Thin
Ifilimu ye-Solar-grade EVA (i-ethylene-vinyl acetate copolymer) iyinxalenye ephambili yokwenziwa kweepaneli zelanga. Isebenza njengomaleko okhuselayo ojikeleze iseli yelanga, ibonelela nge-insulation kunye nokukhusela kwizinto ezisingqongileyo ezifana nokufuma, imitha ye-ultraviolet, kunye noxinzelelo lomatshini. Umgangatho wefilimu ye-EVA ichaphazela ngokuthe ngqo ukusebenza kunye nobomi bepaneli yelanga; ngoko ke, ukukhetha uhlobo olufanelekileyo kubalulekile.
Iifilimu ze-EVA ezicacileyo eziphezulu zithandwa kakhulu kwishishini ngenxa yeempawu zabo eziphezulu. Ezi filimu zifezekisa ukuhanjiswa kokukhanya okuphezulu, okubalulekileyo ekuphuculeni ukusebenza kakuhle kweeseli zelanga. Ukucaca okuphezulu kweefilimu ze-EVA kuqinisekisa ukuba ukukhanya kwelanga kufikelela kwiiseli zelanga, ngaloo ndlela kwandisa ukuphuma kwamandla.
Imiba ephambili emayiqwalaselwe
Xa ukhetha iifilimu ze-solar EVA, ezi zinto zilandelayo kufuneka ziqwalaselwe ukuqinisekisa ukuhlala kwazo ixesha elide kunye nokucaca kwazo:
UkuNgafihli kunye nokuThuthwa kokukhanya:
Umsebenzi ophambili weiifilimu ze-EVA ezicacileyo eziphezulukukuvumela ukukhanya kwelanga kudlule ngokufanelekileyo. Iifilimu ezinokuhanjiswa kokukhanya okuphezulu, ngokuqhelekileyo ngaphezulu kwe-90%, kufuneka zikhethwe. Oku kuqinisekisa ukuba iiseli zelanga zifumana ukukhanya kwelanga okugqibeleleyo, ngaloo ndlela ziphucula ukusebenza kwazo.
Ukumelana neUV:
Iipaneli zelanga zibonakaliswe kwiimeko ezinzima zokusingqongileyo, kubandakanywa nemisebe ye-ultraviolet. Iifilimu ze-EVA ezikumgangatho ophezulu welanga kufuneka zibe nokuxhathisa okugqwesileyo kwe-UV ukunqanda ukutyheli kunye nokwehla kokusebenza kwexesha. Olu phawu lubalulekile ekugcineni ukucaca nokusebenza kweephaneli zelanga kubo bonke ubomi bazo.
Isithintelo sokufuma:
Inkqubo ye-encapsulation kufuneka ikhusele iiseli zelanga kumswakama. Iifilimu ze-EVA ezinomphunga ophantsi wokungena kwamanzi zikhethwa ukuqinisekisa ukuba iiseli zelanga zihlala zomile kwaye zisebenza ngokufanelekileyo, zikhusela umonakalo onokwenzeka kunye nokulahleka kokusebenza kakuhle.
Uzinzo lweThermal:
Iiphaneli zelanga zifumana ukuguquguquka okukhulu kobushushu. Ifilimu ye-EVA ekhethiweyo yelanga kufuneka ibe nokuzinza okuhle kwe-thermal, ekwaziyo ukumelana nolu tshintsho ngaphandle kokuchaphazela ingqibelelo yayo. Ifilimu egcina ukusebenza kwayo kuluhlu olubanzi lobushushu kufuneka ikhethwe.
Ukusebenza kokuncamathela:
Ukubambelela phakathi kwefilimu ye-EVA kunye neseli yelanga kubalulekile ekusebenzeni ngokubanzi kwepaneli yelanga. Kubalulekile ukukhetha ifilimu enamathele ngokuqinileyo ukukhusela i-delamination kunye nokuqinisekisa ukuqina kwexesha elide.
Impembelelo yokusingqongileyo:
Njengoko uphuhliso oluzinzileyo luba lukhulu ngakumbi, nceda uqwalasele impembelelo yokusingqongileyo yezinto ezisetyenziswa kwiipaneli zelanga. Khetha iifilimu ze-EVA eziveliswe kusetyenziswa iinkqubo ezihambelana nokusingqongileyo kunye nezixhobo.
Ukuququmbela
Ukukhetha ifilimu ye-EVA efanelekileyo yelanga, ngakumbi iifilimu zelanga ze-EVA ezibonisa ngokucacileyo phezulu, zibalulekile ekuqinisekiseni ukuqina kwexesha elide kunye nokucaca kweepaneli zelanga. Ngokuqwalasela izinto ezifana nokungafihli, ukuxhathisa kwe-UV, ukuxhathisa ukufuma, ukuzinza kwe-thermal, ukunamathela, kunye nefuthe lokusingqongileyo, unokwenza ukhetho olunolwazi oluphucula ukusebenza kunye nobomi benkqubo yakho yelanga. Utyalo-mali kwiifilimu ze-EVA ezikumgangatho ophezulu welanga akwaneli nje ukwandisa amandla ombane kodwa zikwanegalelo ekwakheni ikamva elizinzileyo.
