Dab tsi yog ob sab, shingled, ib nrab nti thiab MBB multi-busbar hnub ci vaj huam sib luag modules

Lub hnub ci photovoltaic module yog lub hauv paus tseem ceeb ntawm lub hnub ci hluav taws xob tsim hluav taws xob, thiab nws txoj haujlwm yog hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob thiab xa mus rau lub roj teeb cia rau kev cia. Raws li cov khoom siv, feem ntau siv crystalline silicon photovoltaic modules feem ntau yog tsim los ntawm peb qhov chaw: cell, EVA ntim khoom, iav, backplane thiab ncej, thiab junction box.

Hnub ci vaj huam sib luag:

Nws yog lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob hnub ci. Raws li cov nyhuv photovoltaic, nws tuaj yeem tsim cov hluav taws xob dawb nyob rau hauv qhov xwm txheej ntawm lub teeb, thiab tsim ib qho tam sim no nyob rau hauv unidirectional conduction ntawm PN hlws ris, yog li hloov lub hnub ci zog rau hauv hluav taws xob. Tam sim no, kev tsim cov thev naus laus zis ntawm lub hnub ci hlwb suav nrog aluminium backfield (Al-BSF), passivated emitter thiab backfield (PERC), heterojunction (HIT), thiab lwm yam.

EVA encapsulation khoom: Cov thermosetting nplaum zaj duab xis uas muaj EVA yog siv rau laminating lub cell, backplane, thiab iav rau hauv tag nrho los tsim ib qho module.

iav, nraub qaum, thiab thav duab: Cov khoom uas tiv thaiv lub hlwb los ntawm kev puas tsuaj los yog kev puas tsuaj los ntawm lub ntiaj teb sab nraud, ncua kev pab cuam lub neej ntawm cov modules, thiab pab txhawb kev txhim kho tom ntej.

Lub thawv sib txuas: Feem ntau, muaj 60 lossis 72 lub hlwb hauv lub module. Cov hlwb txuas nrog hauv koob los ntawm cov nyiaj muab tshuaj txhuam. Tom qab qhov tam sim no yog tsim nyob rau hauv lub teeb, nws kis tau mus rau lub hlws ris lub thawv los ntawm cov nyiaj muab tshuaj txhuam hlau, thiab ces txuas nrog rau sab nraud roj teeb.

Hnub ciPV module sab hauv qauv:

Lub tshuab hluav taws xob ib nrab yog ib qho cuab yeej siv hluav taws xob uas ua kom lub zog sib npaug, thiab nws ua kom lub zog ua haujlwm tau zoo dua los ua kom muaj kev txhim kho ntau dua. Ib nrab-chip thev naus laus zis superimposed ntawm cov pa polycrystalline modules tuaj yeem nce lub zog los ntawm 5 ~ 6W; tib lub thev naus laus zis tuaj yeem ua rau ntawm monocrystalline perc modules coj ntau dua 8W zog nce. Nyob rau hauv 2018, tag nrho-chip modules suav nrog ntau dua 90 feem pua ​​​​ntawm cov feem. Lub tshuab ib nrab-chip txo cov kev tawm tsam hauv cov qauv, txo qis hauv lub zog poob, thiab txhim kho kev hloov dua siab tshiab. Lub tshuab ib nrab nti yog paub tab thiab cov txiaj ntsig tau lav. Tam sim no muaj peev xwm tsim tau yog li 15GW, thiab nws yuav tsum maj mam hloov cov nti tag nrho yav tom ntej.

Shingling muaj peev xwm thiab kwv yees hauv 2017-2021 (GW)

Lub npe hu ua shingling technology yog hais txog kev txiav cov roj teeb ib txwm siv rau hauv 1/5, siv cov kua nplaum txuas ncaj qha rau ob lub roj teeb, sib txuas thiab sib dhos ua ke, thiab tom qab ntawd txuas cov roj teeb hauv cov kab ntawm lub hauv paus no. Nyob rau hauv txoj kev no, qhov 2-3 hli ntawm tes qhov sib nrug tshwj tseg hauv cov qauv qub tuaj yeem raug tshem tawm, thiab ntau lub hlwb tuaj yeem thauj khoom hauv tib cheeb tsam. Feem ntau hais lus, ib qho piv txwv 60- hom module tuaj yeem thauj 66 hlwb.

Tsis tas li ntawd, txij li cov tshuab shingled siv cov nplaum nplaum es tsis txhob vuam daim kab xev rau kev sib kis tam sim no, tsis muaj teeb meem nrog cov vuam daim kab xev npog thaj chaw txais lub teeb pom kev zoo hauv cov khoom siv ib txwm, yog li qhov chaw txais lub teeb pom kev zoo ntawm shingled module. yog loj dua li ntawm cov tsoos module, uas ntxiv txhim kho cov stacking kev ua tau zoo. Lub conversion efficiency ntawm pobzeb Cheebtsam. Shingling thev naus laus zis yog qhov tseem ceeb thev naus laus zis tshiab ntawm photovoltaic module technology. Shingling tau hloov txoj kev mus sij hawm ntev ntawm kev siv vuam daim kab xev rau hluav taws xob txuas hlwb, ua kom lub teeb pom kev zoo ntawm photovoltaic modules. Lub peev xwm ntau lawm ntawm shingled modules kuj tau nce ntau txij li lub xyoo no, tab sis vim muaj kev txhawj xeeb ntev ntawm kev ua txhaum cai patent hauv shingled thev naus laus zis, kev ua lag luam kawg yog qhov txwv. Rau kev xa tawm txawv teb chaws, cov shingled modules ntawm cov tuam txhab feem ntau tseem yog cov khoom siv hauv tsev hauv Suav teb.

Los ntawm qhov kev xav ntawm cov txheej txheem ntws ntawm shingled Cheebtsam, thawj qhov nyuaj nyob rau hauv cov teeb meem xws li tawg thiab kev puas tsuaj uas yuav tshwm sim thaum lub sij hawm slicing txheej txheem; Qhov thib ob yog tias nyob rau hauv cov txheej txheem vuam, nws yog ib qho tsim nyog yuav tsum tau siv ib qho tshwj xeeb stringer rau shingling. Xav tau. Feem ntau, cov txheej txheem uas cuam tshuam rau cov txiaj ntsig ntawm shingled Cheebtsam muaj xws li laser txiav, roj teeb sawb teeb, roj teeb sawb vuam, thiab lwm yam. Tsis tas li ntawd, lwm cov txheej txheem thiab cov khoom siv yuav tsum yog tib yam li cov khoom siv sib xyaw.
