Ososayensi baseSpain bahlole amamojula e-PV ngaphansi kwezimo ze-shading ingxenye, okuhloswe ngayo ukuqonda kangcono ukwakheka kwezindawo ezishisayo ezilimaza ukusebenza.Ucwaningo luveza inkinga engase ibe khona ethinta ikakhulukazi amamojula e-half-cell kanye ne-bifacial, engase ibangele ukulahleka kokusebenza okusheshisiwe futhi ayimboziwe izindinganiso zamanje zokuhlola/izitifiketi.
Esifundweni, amamojula wephaneli yelanga afakwe umthunzi ngenhloso ukuze enze izindawo ezishisayo.
Ukusika amaseli e-silicon phakathi, nokuwenza akwazi ukukhiqiza ugesi kusukela ekukhanyeni kwelanga okushaya izinhlangothi zombili, kuyizindlela ezintsha ezimbili ezilethe ithuba lokukhuphuka kwesivuno samandla ngezindleko zokukhiqiza ezengeziwe.Ngakho-ke, zombili lezi zikhule ngokushesha eminyakeni embalwa edlule, futhi manje zimelela inkambiso ekukhiqizeni amaseli elanga kanye namamojula.
Ucwaningo olusha, obeluphakathi kwabaphumelele indondo yephosta e-Ingqungquthela ye-EU PVSECebibanjelwe e-Lisbon ngenyanga edlule, ibonise ukuthi inhlanganisela yemiklamo ye-half-cut kanye ne-bifacial cell ingase ibe nomthelela ekwakhiweni kwe-hotspot kanye nezinkinga zokusebenza, ngaphansi kwezimo ezithile.Futhi izindinganiso zamanje zokuhlola, ababhali bocwaningo baxwayise, kungenzeka bangahlonyiselwe ukubona amamojula asengozini yalolu hlobo lokucekelwa phansi.
Abacwaningi, abaholwa umxhumanisi wezobuchwepheshe oseSpain i-Enertis Applus, bahlanganisa izingxenye zemojula ye-PV ukuze babheke ukuziphatha kwayo ngaphansi komthunzi oyingxenye."Siphoqe ukuthi ithunzi lingene ngokujulile ekuziphatheni kwamamojula e-monofacial kanye ne-bifacial half-cell, sigxile ekwakhekeni kwendawo eshisayo kanye namazinga okushisa lawa mabala afika kuwo," kuchaza uSergio Suárez, umphathi wezobuchwepheshe emhlabeni wonke kwa-Enertis Applus.Kuyathakazelisa ukuthi sihlonze izindawo ezishisayo ezibukeka njengezibuko ezivela endaweni ehlukile maqondana nezindawo ezishisayo ezijwayelekile ngaphandle kwezizathu ezisobala, njengokufiphala noma ukuphuka.
Ukuwohloka okusheshayo
Ucwaningo lubonise ukuthi idizayini ye-voltage yamamojula anguhhafu weseli ingase ibangele izindawo ezishisayo ukuthi zisabalale ngale kwendawo enomthunzi/elimele."Amamojula angama-half cell anikeze isimo esithakazelisayo," kuqhubeka uSuárez.“Lapho kuvela i-hotspot, idizayini ye-module ye-voltage ehambisanayo iphusha ezinye izindawo ezingathinteki ukuthi zithuthukise izindawo ezishisayo.Lokhu kuziphatha kungase kubonise ukuwohloka okungase kube khona ngokushesha kumamojula we-half-cell ngenxa yokuvela kwalezi zindawo ezishisayo eziphindaphindekile. "
Umphumela uphinde waboniswa ukuthi unamandla ikakhulukazi kumamojula we-bifacial, afinyelele izinga lokushisa le-hotspot kufika ku-10 C ephakeme kunamamojula anohlangothi olulodwa ocwaningweni.Amamojula ahlolwe phakathi nenkathi yezinsuku ezingu-30 ngaphansi kwezimo eziphakeme zokungabi nalutho, anesibhakabhaka esinamafu nesicacile.Ucwaningo maduze luzoshicilelwa ngokugcwele, njengengxenye yezinqubo zomcimbi we-2023 EU PVSEC.
Ngokwabacwaningi, le miphumela yembula indlela eya ekulahlekelweni kokusebenza okungahlanganisiwe kahle ngamazinga okuhlola amamojula.
“I-hotspot eyodwa engxenyeni engezansi yemojuli ingase ibangele izindawo eziningi ezishisayo, okuthi, uma ingaxazululwa, isheshise ukuwohloka kwayo yonke indawo ngokukhuphuka kwezinga lokushisa,” kusho u-Suárez.Uphinde waphawula ukuthi lokhu kungabeka ukubaluleka okwengeziwe emisebenzini yokulungisa njengokuhlanza amamojula, kanye nokuhlelwa kwesistimu nokupholisa umoya.Kodwa ukubona inkinga kusenesikhathi kungaba kuhle kunalokhu, futhi kudinga izinyathelo ezintsha zokuhlola nokuqinisekiswa kwekhwalithi esigabeni sokukhiqiza.
"Esikutholile kugqamisa isidingo kanye nethuba lokuhlola kabusha futhi mhlawumbe nokubuyekeza izindinganiso ze-half cell kanye nobuchwepheshe be-bifacial," kusho u-Suárez."Kubalulekile ukufaka i-thermography, ukwethula amaphethini athile okushisa ama-half-cell futhi ulungise ukujwayela kwama-thermal gradients kuya ku-Standard Test Conditions (STC) kumamojula we-bifacial."
