Yuav kom ua tau raws li qhov xav tau ntawm lub zog loj zuj zus, kev lag luam hluav taws xob tshiab tau nthuav dav hauv tsib xyoos dhau los.Ntawm lawv, kev lag luam Photovoltaic tau dhau los ua qhov chaw kub hauv kev lag luam hluav taws xob tshiab vim nws txoj kev ntseeg siab thiab ruaj khov, kev pab lub neej ntev thiab kev teeb tsa yooj yim.Yog tias koj nyuam qhuav muaj lub tswv yim ntawm kev yuav cov hnub ci vaj huam sib luag lossis pv module, tab sis tsis paub yuav xaiv li cas.Tsuas yog saib ntawm kab lus no.
Cov ntaub ntawv tseem ceeb ntawm solar panels:
Hnub ci vaj huam sib luag yog cov cuab yeej siv los ntes lub zog ntawm lub hnub, lawv nqus cov hnub ci thiab tsim hluav taws xob los ntawm kev hloov photon rau hauv hluav taws xob, thiab cov txheej txheem ntawd hu ua Photovoltaic effect.Thaum lub hnub ci ci rau ntawm lub hnub ci vaj huam sib luag, cov photoelectrons ntawm lub vaj huam sib luag tau txhawb nqa los ntawm lub hnub ci hluav taws xob, tso cai rau lawv tsim cov duab photoelectron.Ib qho hluav taws xob ntws mus rau lub anode thiab lwm yam hluav taws xob ntws mus rau cathode, tsim txoj hauv kev tam sim no.Silicon panels muaj kev pab cuam lub neej ntawm ntau tshaj 25 xyoo, tab sis nrog kev nce ntawm kev siv sij hawm, lawv efficiency yuav degrade nyob rau hauv ib tug ceev ntawm txog 0.8% ib xyoos twg.Yog li tsis txhob txhawj, txawm tias tom qab 10 xyoo siv, koj cov vaj huam sib luag tseem ua kom muaj txiaj ntsig zoo.
Niaj hnub no, cov khoom lag luam tseem ceeb hauv kev ua lag luam suav nrog monocrystalline panels, polycrystalline panels, PERC panels thiab nyias-film panels.
Ntawm cov hom hnub ci vaj huam sib luag, monocrystalline panels yog qhov ua tau zoo tshaj plaws tab sis kuj yog qhov kim tshaj plaws.Qhov no yog vim cov txheej txheem tsim khoom - vim hais tias lub hnub ci hlwb yog tsim los ntawm ib tus neeg silicon crystals, manufacturers yuav tsum tau them tus nqi ntawm kev ua cov crystals.Cov txheej txheem no, hu ua tus txheej txheem Czochralase, yog lub zog siv zog thiab tsim cov khoom siv silicon (uas tuaj yeem siv los tsim cov hnub ci polycrystalline).
Txawm hais tias nws yog kim dua li polycrystalline panels, nws muaj txiaj ntsig thiab ua haujlwm siab.Vim yog kev sib cuam tshuam ntawm lub teeb thiab ntshiab silicon, monocrystalline panels tshwm nyob rau hauv dub, thiab feem ntau yog dawb los yog dub tom qab.Piv nrog rau lwm cov vaj huam sib luag, nws muaj qhov ua kom sov siab, thiab ua kom muaj zog ntau dua nyob rau hauv qhov kub thiab txias.Tab sis nrog txoj kev loj hlob ntawm kev siv tshuab thiab kev txhim kho ntawm silicon ntau lawm, monocrystallien panels tau dhau los ua cov khoom tseem ceeb hauv kev ua lag luam.Yog vim li cas yog qhov txwv ntawm polycrystalline silicon hauv kev ua haujlwm, uas tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 20%, thaum qhov ua tau zoo ntawm monocrystalline panels feem ntau yog 21-24%.Thiab tus nqi sib txawv ntawm lawv yog nqaim, yog li ntawd, monocrystalline panels yog qhov kev xaiv dav tshaj plaws.
Polycrystalline panels yog tsim los ntawm silicon wafer, uas yooj yim rau cov txheej txheem ntawm kev tsim cov roj teeb - tus nqi qis, tus nqi qis.Tsis zoo li monocrystalline panels, polycrystalline panels cell yog xiav thaum xav txog lub teeb.Qhov ntawd yog qhov sib txawv ntawm silicon fragments thiab ntshiab silicon siv lead ua xim.
PERC stands rau Passivated Emitter thiab Rear Cell, thiab tseem hu ua 'rov qab cell', uas yog tsim nyob rau hauv advanced technology.Hom hnub ci vaj huam sib luag no muaj txiaj ntsig zoo dua los ntawm kev ntxiv txheej tom qab hnub ci hlwb.Cov vaj huam sib luag hnub ci nqus hnub ci tsuas yog rau qee qhov, thiab qee qhov teeb pom kev ncaj qha los ntawm lawv.Cov txheej ntxiv hauv PERC lub hnub ci vaj huam sib luag tuaj yeem nqus tau lub teeb hla dua thiab txhim kho kev ua haujlwm.PERC thev naus laus zis feem ntau yog siv hauv cov vaj huam sib luag monocrystalline, thiab nws lub zog ntsuas yog qhov siab tshaj plaws ntawm cov hnub ci vaj huam sib luag ntawm lub khw.
Sib txawv ntawm monocrystalline panels thiab polycrystalline panels, nyias-zaj duab xis panels yog ua los ntawm lwm yam ntaub ntawv, uas feem ntau yog hais txog: cadmium telluride (CdTe) thiab tooj liab indium gallium selenide (CIGS).Cov ntaub ntawv no tau muab tso rau hauv iav los yog yas backplanes es tsis txhob silicon, ua rau nyias-zaj duab xis panels yooj yim rau nruab.Yog li ntawd, koj tuaj yeem txuag tau ntau tus nqi installation.Tab sis nws cov kev ua tau zoo hauv kev ua tau zoo yog qhov phem tshaj plaws, nrog kev ua haujlwm siab tshaj ntawm tsuas yog 15%.Tsis tas li ntawd, nws muaj lub neej luv luv piv rau monocrystalline panels thiab polycrystalline panels.
Koj tuaj yeem xaiv cov panels zoo li cas?
Nws nyob ntawm koj qhov kev xav tau thiab ib puag ncig koj siv nws.
Ua ntej, yog tias koj yog ib tus neeg siv nyob hauv tsev thiab muaj thaj chaw txwv los tso lub hnub ci vaj huam sib luag.Tom qab ntawd cov hnub ci vaj huam sib luag nrog kev ua haujlwm siab dua xws li monocrystalline panels lossis PERC monocrystalline panels yuav zoo dua.Lawv muaj lub zog tso zis ntau dua thiab vim li no yog qhov kev xaiv zoo tshaj plaws rau thaj chaw me me kom ua kom muaj peev xwm loj tshaj plaws.Yog tias koj ntxhov siab nrog cov nqi hluav taws xob siab lossis coj nws los ntawm kev nqis peev los ntawm kev muag hluav taws xob rau cov tuam txhab hluav taws xob hluav taws xob, monocrystalline panels yuav tsis cia koj poob.Txawm hais tias nws raug nqi ntau dua li polycrystalline panels nyob rau theem ua ntej, tab sis nyob rau hauv ntev, nws muab lub peev xwm ntau dua thiab pab koj txo koj cov nqi hluav taws xob.Thaum koj cov nyiaj khwv tau los hauv kev txuag nqi thiab muag hluav taws xob (yog tias koj lub inverter nyob rau hauv daim phiaj) npog cov nqi ntawm cov khoom siv photovoltaic, koj tuaj yeem tau them los ntawm kev muag hluav taws xob.Qhov kev xaiv no kuj tseem siv tau rau cov chaw tsim khoom lossis cov tsev lag luam uas txwv qhov chaw.
Qhov teeb meem rau kev txhim kho polycrystalline panels yog pom tseeb ntawm qhov tsis sib xws.Vim lawv cov nqi qis, nws muaj feem xyuam rau cov chaw tsim khoom lossis cov tsev lag luam uas muaj chaw txaus rau nruab panels.Vim tias cov chaw no muaj qhov chaw txaus los tso cov hnub ci vaj huam sib luag los ua kom tsis muaj kev ua haujlwm zoo.Rau qhov zoo li no, polycrystalline panels muab cov nqi zoo.
Raws li rau nyias-zaj duab xis panels, lawv feem ntau siv nyob rau hauv loj-scale nqi hluav taws xob qhov project vim lawv cov nqi qis thiab efficiency los yog lub ru tsev ntawm loj coj mus muag vaj tse uas tsis tuaj yeem txhawb nqa qhov hnyav ntawm lub hnub ci vaj huam sib luag.Lossis koj tuaj yeem muab tso rau hauv Cov Tsheb Ua Si thiab cov nkoj ua 'cov nroj tsuag nqa tau'.
Tag nrho cov nyob rau hauv tag nrho cov, xaiv kom zoo zoo thaum muas lub hnub ci vaj huam sib luag, raws li lawv lifespan yuav ncav cuag 20 xyoo nyob rau nruab nrab.Tab sis nws tsis nyuaj li koj xav, tsuas yog raws li qhov zoo thiab qhov tsis zoo ntawm txhua hom hnub ci vaj huam sib luag, thiab ua ke nrog koj tus kheej xav tau, ces koj tuaj yeem tau txais cov lus teb zoo meej.
