Yini efika emqondweni uma uzwa ngobuchwepheshe bebhethri le-BC?
Kwabaningi, "ukusebenza okuphezulu namandla aphezulu" yimicabango yokuqala. Ngokuvumelana nalokhu, izingxenye ze-BC ziziqhayisa ngokusebenza kahle kakhulu kokuguqulwa phakathi kwazo zonke izingxenye ezisekelwe ku-silicon, njengoba zisethe amarekhodi amaningi omhlaba. Kodwa-ke, ukukhathazeka okufana "nezinga eliphansi le-bifacial ratio" nakho kuyaphawulwa. Imboni ibona izingxenye ze-BC njengezisebenza kahle kakhulu nokho ezinenani eliphansi le-bifacial, elibonakala lifaneleka kakhulu ukukhiqiza ugesi ohlangothi olulodwa, okubangela ukuthi amanye amaphrojekthi abaleke ngenxa yokwesaba ukwehlisa ukukhiqizwa kwamandla sekukonke.
Nokho, kubalulekile ukuqaphela intuthuko ebalulekile. Okokuqala, ukuthuthukiswa kobuchwepheshe bezinqubo kwenze izingxenye zebhethri ze-BC zikwazi ukuzuza izilinganiso ezingemuva ezingama-60% noma ngaphezulu, ukuvala igebe ngobunye ubuchwepheshe. Ngaphezu kwalokho, akuwona wonke amaphrojekthi we-photovoltaic aqaphela ngaphezu kokunyuka kwe-15% esizukulwaneni esingemuva; abaningi babona ngaphansi kuka-5%, kunomthelela omncane kunalokho obekucatshangwa. Naphezu kwamandla aphansi asemuva, izinzuzo ku-front-sidepower zingasinxephezela kakhulu. Ophahleni lwezindlu ezinosayizi olinganayo, i-BC izingxenye zebhethri ezizinhlangothi zombili zingakhiqiza ugesi owengeziwe. Ochwepheshe bemboni baphakamisa ukuthi kugxilwe kakhulu ezindabeni ezinjengokonakaliswa kwamandla, umonakalo, kanye nokunqwabelana kothuli ezindaweni ezingaphezulu, okungaba nomthelela omkhulu ekuphehlisweni kukagesi.
Embukisweni wakamuva we-China (Shandong) we-New Energy and Energy Storage Application Expo, i-Longi Green Energy yenze umthelela omkhulu ngokwethulwa kwamamojula ayo ayingilazi ephindwe kabili ye-Hi-MO X6 aklanyelwe ukumelana nomswakama nokushisa, enikeza izinketho eziningi emakethe futhi athuthuke. Ukuvumelana nezimo zezinhlelo ze-photovoltaic kuzimo zezulu eziyinkimbinkimbi. U-Niu Yanyan, umongameli we-Longi Green Energy's Distributed Business e-China, ugcizelele ukuzibophezela kwenkampani ekunciphiseni ubungozi obungaba khona kumakhasimende, njengoba ukufakwa kwe-photovoltaic kuwutshalomali olukhulu. Izingozi ezihlobene nezindawo ezinomswakama nezishisayo, ngokuvamile ezibukelwa phansi, zingaholela ekulimaleni kwe-electrode kumamojula ngaphansi kwezinga lokushisa eliphezulu kanye nomswakama, okubangela ukuncipha kwe-PID futhi kuthinte ukukhiqizwa kwamandla omjikelezo wokuphila wamamojula.
Idatha yeNational Energy Administration ibonisa ukuthi ekupheleni kuka-2023, ukufakwa kwe-photovoltaic okuhlanganisiwe e-China kwafinyelela cishe ku-609GW, cishe u-60% otholakala ezindaweni ezisogwini, eduze nolwandle, noma ezindaweni ezinomswakama njengaseNingizimu China naseNingizimu-ntshonalanga yeChina. Ezimeni ezisabalalisiwe, ukufakwa ezindaweni ezinomswakama kufinyelela ku-77.6%. Ukunganaki ukumelana namamojula kumswakama nokushisa, ukuvumela umhwamuko wamanzi nenkungu kasawoti ukuba iwaqede, kungase kuthuntubeze kakhulu ukusebenza kwamamojula e-photovoltaic phakathi neminyaka edlule, kunciphise imbuyiselo elindelekile yabatshalizimali. Ukuze kubhekwane nale nselelo yomkhakha, uLongi uthuthukise umswakama wengilazi ephindwe kabili ye-Hi-MO X6 kanye namamojula amelana nokushisa, azuze impumelelo ebanzi kusukela ekwakhiweni kwamaseli kuya ekupakishweni, eqinisekisa ukuphehlwa kukagesi okusebenzayo nokuthembekile ngisho nasezimeni ezinomswakama nezishisayo, ngokusho kukaNiu. Yanyan.
Amamojula engilazi ephindwe kabili e-Hi-MO X6 agqama kakhulu ngokumelana kwawo nezimo zezulu. I-HPBC yebhethri ye-electrode material, engenawo ingxubevange yesiliva-aluminium, ngokwemvelo ijwayele ukuthambekela ekuphenduleni kwe-electrochemical. Ukwengeza, amamojula asebenzisa inqubo yefilimu ye-POE enezinhlangothi ezimbili, enikeza ukumelana nomswakama ophindwe kasikhombisa kwe-EVA, futhi isebenzisa iglue yokuvala uphawu ephezulu engazwani nomswakama ukuze ifakwe, ivimbe amanzi ngempumelelo.
Imiphumela yokuhlolwa evela esikhungweni sesithathu i-DH1000 iveze ukuthi ngaphansi kwemibandela engu-85°Izinga lokushisa elingu-C kanye nomswakama ongu-85%, ukuncishiswa kwamamojula kube ngu-0.89% kuphela, ngaphansi kakhulu kwe-IEC's (International Electrotechnical Commission) 5% izinga lezimboni. Imiphumela yokuhlolwa kwe-PID ibiphansi ngokumangazayo ku-1.26%, isebenze kakhulu kunemikhiqizo yezimboni eqhathanisekayo. U-Longi uthi amamojula e-Hi-MO X6 ahola imboni ngokuphelelwa amandla, ngokuwohloka ngo-1% ngonyaka wokuqala kanye nezinga lokuwohloka elingu-0.35% kuphela. Ngewaranti yamandla yeminyaka engu-30, amamojula aqinisekisiwe ukuthi agcina amandla awo angaphezulu kuka-88.85% ngemva kweminyaka engu-30, azuza ku-coefficient yamandla okushisa alungiselelwe -0.28%.
Ukukhombisa ukumelana kwamamojula kumswakama nokushisa ngokucace kakhudlwana, abasebenzi bakwaLongi bacwilisa ingxenye eyodwa yemojuli emanzini ashisayo ngaphezu kuka-60.°C ngesikhathi sombukiso. Idatha yokusebenza ayizange ibonise umthelela, okubonisa ukuqina komkhiqizo ngokumelene nomswakamo nokushisa ngendlela eqondile. U-Lv Yuan, umongameli we-Longi Green Energy Distributed Business Product and Solutions Center, ugcizelele ukuthi ukwethembeka kuyinani eliyinhloko le-Longi, elibeka phambili ngaphezu kwakho konke. Naphezu kwemizamo yokunciphisa izindleko esheshayo yemboni, i-Longi igcina izindinganiso eziphakeme kugqinsi lwe-silicon wafer, ingilazi, nekhwalithi yozimele, yenqaba ukuyekethisa ekuphepheni ngokuncintisana kwezindleko.
U-Niu Yanyan uphinde wagqamisa ifilosofi kaLongi yokugxila kumkhiqizo nekhwalithi yesevisi phezu kwezimpi zamanani, ekholelwa ekuletheni inani kumakhasimende. Unesiqiniseko sokuthi amakhasimende, abale kahle ukubuyiselwa kwemali, azolibona inani elengeziwe: Imikhiqizo kaLongi ingase ibe nenani elingaphezulu ngo-1%, kodwa ukunyuka kwemali etholwayo yokuphehla ugesi kungafinyelela ku-10%, isibalo esingasijabulela noma yimuphi umtshali-zimali.
I-Sobey Consulting ibikezela ukuthi ngo-2024, ukufakwa kwe-photovoltaic esabalalisiwe kwase-China kuzofinyelela phakathi kuka-90-100GW, nemakethe ebanzi nakakhulu phesheya kwezilwandle. Amamojula we-Hi-MO X6 anengilazi ephindwe kabili yokuswakama nokumelana nokushisa, anikeza ukusebenza kahle okuphezulu, amandla, kanye nokonakala okuphansi, anikeza inketho ekhangayo emqhudelwaneni okhulayo emakethe esabalalisiwe.
