Kusukela ngo-2022, amaseli ohlobo lwe-n nobuchwepheshe bemojula bebelokhu bethola ukunakwa okukhulayo okuvela kumabhizinisi amaningi okutshala amandla, njengoba isabelo sawo semakethe sikhula ngokuqhubekayo. Ngo-2023, ngokwezibalo ze-Sobey Consulting, ingxenye yokuthengisa yohlobo lwe-n-type emabhizinisini amaningi ahamba phambili e-photovoltaic ngokuvamile yeqa ama-30%, ezinye izinkampani zedlula ngisho no-60%. Ngaphezu kwalokho, amabhizinisi e-photovoltaic angekho ngaphansi kwe-15 asebeke ngokusobala umgomo "wokweqa ingxenye yokuthengisa engu-60% yemikhiqizo yohlobo lwe-n ngo-2024".
Mayelana nemizila yezobuchwepheshe, ukukhetha kwamabhizinisi amaningi kuwuhlobo lwe-n-TOPCon, nakuba abanye bekhethe izixazululo zobuchwepheshe zohlobo lwe-n-HJT noma i-BC. Isiphi isixazululo sobuchwepheshe futhi hlobo luni lwenhlanganisela yemishini engaletha ukusebenza kahle okuphezulu kokuphehla amandla, ukukhiqizwa kwamandla aphezulu, kanye nezindleko eziphansi zikagesi? Lokhu akuthinti nje kuphela izinqumo zesu lokutshala izimali zezinkampani kodwa futhi kunomthelela ekukhethweni kwezinkampani zokutshala amandla ngesikhathi sohlelo lokubhida.
Ngomhla zingama-28 kuNdasa, i-National Photovoltaic and Energy Storage Demonstration Platform (i-Daqing Base) ikhiphe imiphumela yedatha yonyaka wezi-2023, okuhloswe ngayo ukuveza ukusebenza kwezinto ezihlukahlukene, izakhiwo, nemikhiqizo yobuchwepheshe ngaphansi kwezindawo zokusebenza zangempela. Lokhu okokunikeza ukwesekwa kwedatha kanye neziqondiso zemboni zokukhuthaza nokusebenzisa ubuchwepheshe obusha, imikhiqizo emisha, nezinto ezintsha, ngaleyo ndlela kube lula ukuphindwaphindwa nokuthuthukiswa komkhiqizo.
U-Xie Xiaoping, usihlalo wekomiti lezemfundo yesikhulumi, uveze embikweni:
Izici ze-Meteorological kanye ne-irradiation:
I-irradiation ngo-2023 yayiphansi kunesikhathi esifanayo ngo-2022, kukho kokubili okuvundlile nokuthambekele (45°) kwehle ngo-4%; isikhathi sokusebenza sonyaka ngaphansi kokushiswa kwemisebe ephansi sasiside, nokusebenza okungaphansi kuka-400W/m² okubalelwa ku-53% wesikhathi; i-irradiation yonyaka evundlile engemuva ibalelwa ku-19%, kanye nemisebe engemuva (45°) engemuva yayingama-14%, empeleni eyayifana neyango-2022.
Ukubukeka kwemojuli:
amamojula asebenza kahle kakhulu ohlobo lwe-n ayenamandla okukhiqiza amandla aphakeme, ahambisana nenkambiso yango-2022. Ngokuphathelene nokuphehlwa kukagesi ngemegawathi ngayinye, i-TOPCon ne-IBC zaziphakeme ngo-2.87% kanye no-1.71% ngaphezu kwe-PERC; amamojula anosayizi omkhulu abenamandla okuphehla amandla aphezulu, umehluko omkhulu ekuphehlisweni kukagesi ucishe ube ngu-2.8%; kube nomehluko ekulawuleni ikhwalithi yenqubo yamamojula phakathi kwabakhiqizi, okuholele kumehluko omkhulu ekusebenzeni kwamamojula okukhiqizwa kwamandla. Umehluko wokuphehla amandla phakathi kobuchwepheshe obufanayo obuvela kubakhiqizi abahlukene ungaba ngu-1.63%; izilinganiso zokuwohloka kwabakhiqizi abaningi zihlangabezane “Nezincazelo Zemboni Yokukhiqiza I-Photovoltaic (Ushicilelo lwango-2021)”, kodwa ezinye zeqa izimfuneko ezijwayelekile; izinga lokuwohloka kwamamojula asebenza kahle kakhulu ohlobo lwe-n laliphansi, kanti i-TOPCon yehlisa isithunzi phakathi kwe-1.57-2.51%, i-IBC yehlisa isithunzi phakathi kuka-0.89-1.35%, i-PERC yehlisa isithunzi phakathi kuka-1.54-4.01%, kanye ne-HJT yehlisa isithunzi kuze kufike ku-8.82% ngenxa yokungaqini ubuchwepheshe be-amorphous.
Isici se-inverter:
Amathrendi okukhiqiza amandla ama-inverter obuchwepheshe ahlukene abelokhu ehambisana phakathi neminyaka emibili edlule, ama-inverter ezintambo akhiqiza amandla aphakeme kakhulu, angu-1.04% kanye no-2.33% aphezulu kunama-inverters aphakathi nendawo nasatshalaliswa, ngokulandelana; ukusebenza kahle kwangempela kobuchwepheshe obuhlukene kanye nama-inverter abakhiqizi bekuzungeze u-98.45%, ne-IGBT yasekhaya kanye nama-inverter e-IGBT angenisiwe anomehluko wokusebenza kahle ongaphakathi kuka-0.01% ngaphansi kwemithwalo ehlukene.
Isici sesakhiwo sokusekela:
Izisekelo zokulandelela zibe nokukhiqiza amandla afanele. Uma kuqhathaniswa nokusekelwa okungaguquki, ukulandelela kwe-eksisi ekabili kusekela ukukhushulwa kwamandla ngo-26.52%, i-axis eyodwa eqondile isekela ngo-19.37%, isekela i-axis eyodwa ethambekele ngo-19.36%, i-axis eyodwa eyisicaba (ene-10 ° tilt) ngo-15.77%, ukusekelwa kwe-omni-directional ngo-12.26%, kanye nezisekelo ezilungisekayo ezingaguquki ngo-4.41%. Ukukhiqizwa kwamandla kwezinhlobo ezahlukene zezisekelo kuthinteke kakhulu ngenkathi.
Isici sesistimu ye-Photovoltaic:
Izinhlobo ezintathu zezinhlelo zokuklama ezinamandla okukhiqiza amandla aphakeme kakhulu zonke zazingama-trackers we-dual-axis + amamojula we-bifacial + inverters yezintambo, i-single-axis eyisicaba (ene-10 ° tilt) isekela + amamojula we-bifacial + inverters yezintambo, kanye nezisekelo ze-axis eyodwa ezithambekele + amamojula we-bifacial + inverters yezintambo.
Ngokusekelwe emiphumeleni yedatha engenhla, u-Xie Xiaoping wenze iziphakamiso ezimbalwa, okuhlanganisa ukuthuthukisa ukunemba kokubikezela kwamandla e-photovoltaic, ukwandisa inani lamamojula ochungechungeni ukuze kwandiswe ukusebenza kwemishini, ukukhuthaza ama-tracker e-single-axis ayisicaba anokutsheka kubanda- izindawo zokushisa, ukuthuthukisa izinto zokuvala kanye nezinqubo zamaseli e-Heterojunction, ukwandisa imingcele yokubala yokukhiqiza amandla esistimu ye-module ye-bifacial, nokuthuthukisa amasu okuklama nokusebenza kweziteshi zokugcina ze-photovoltaic.
Kwethulwa ukuthi i-National Photovoltaic and Energy Storage Demonstration Platform (Daqing Base) ihlele cishe izikimu zokuhlola ezingama-640 phakathi nesikhathi “soHlelo Lweminyaka Eyishumi Nane”, ezinezinhlelo ezingekho ngaphansi kwe-100 ngonyaka, ezihumushela esikalini esingaba ngu-1050MW. Isigaba sesibili sesisekelo sakhiwe ngokugcwele ngoJuni 2023, ngamapulani okusebenza ngokugcwele ngoMashi 2024, futhi isigaba sesithathu saqala ukwakhiwa ngo-Agasti 2023, sekuqediwe ukwakhiwa kwesisekelo senqwaba kanye namandla okusebenza agcwele ahlelwa ekupheleni kuka-2024.
