Kev ceev faj los ntawm cov hauv paus loj mus rau cov chaw tsim hluav taws xob photovoltaic

Kev lag luam photovoltaic yog ushering nyob rau hauv ib tug tshiab puag ncig ntawm txoj kev loj hlob voj voog uas hloov nrog txhua hnub dhau mus. Raws li cov nthwv dej loj ntawm cov hom phiaj ntawm cov pa roj carbon monoxide, lub zog tshiab uas sawv cev los ntawm photovoltaics thiab cua zog tau dhau los ua cov qauv tseem ceeb hauv cov pa roj carbon tsawg, thiab 2021 yuav teeb tsa lub peev xwm tshiab txhua xyoo. Cov ntaub ntawv, lub zog tshiab tau nkag mus rau lub sijhawm muaj kev cia siab ntawm txoj hauv kev zoo.

Ntawm qhov tod tes, nyob rau hauv lub ntsej muag ntawm lub sijhawm tshiab ntawm txoj kev loj hlob, los ntawm cov ntaub ntawv ntau lub zog nyob rau hauv cov cua thiab Everbright lub hauv paus tej yaam num mus rau kev txhawb nqa ntawm kev faib photovoltaics thoob plaws hauv lub nroog, photovoltaic fais fab nroj tsuag tau tsim ntau ntau yam kev thov scenarios. Tab sis tib lub sijhawm, qhov nce ntawm tus nqi ntawm cov khoom siv hluav taws xob photovoltaic hauv ob xyoos dhau los kuj tseem cuam tshuam rau kev nqis peev ntawm kev rov qab los ntawm kev lag luam. Yuav ua li cas txuas ntxiv txo cov nqi thiab tsim kom muaj kev nyab xeeb thiab txhim khu kev qha photovoltaic fais fab nroj tsuag tau dhau los ua qhov kev sib tw tshiab rau kev txhim kho kev lag luam.

Multi-scenario daim ntawv thov: qhov kev sib tw ntawm tus nqi txo thiab kev ruaj ntseg

Raws li kev teeb tsa ib puag ncig ntawm photovoltaic fais fab nroj tsuag ua ntau thiab ntau haiv neeg, txawm hais tias nws yog huab cua yam ntxwv ntawm qhov kub thiab txias ultraviolet hluav taws xob nyob rau hauv cov cheeb tsam arid, los yog high humidity thiab high tshav kub scene nyob rau hauv dej nto thiab av noo, qhov kev loj hlob tshiab qauv. muab tso rau pem hauv ntej kev ntseeg tau thiab kev nyab xeeb ntawm photovoltaic khoom technology. siab dua cov qauv thiab cov kev xav tau. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias, piv nrog cov chaw tsim hluav taws xob hauv av, cov chaw tsim hluav taws xob photovoltaic ru tsev muaj kev pheej hmoo loj dua. Vim yog qhov kub thiab txias ntawm kev ua haujlwm siab thiab muaj kev cuam tshuam siab ntawm lub ru tsev, nws yog ib qho yooj yim ua rau kub kub, thiab muaj ntau qhov teeb meem ntawm hluav taws kub hauv ru tsev photovoltaic fais fab nroj tsuag hauv tsev thiab txawv teb chaws.

Raws li qhov chaw nres tsheb fais fab photovoltaic faib nrog ntau txhiab tsev neeg thiab txhua qhov chaw ntawm lub neej, qhov tseem ceeb ntawm kev nyab xeeb yog qhov tseeb. "Los ntawm kev xav txog kev nqis peev, kev ua haujlwm nyab xeeb ntawm cov chaw tsim hluav taws xob photovoltaic yog qhov tseem ceeb tshaj plaws. Thaum muaj xwm txheej tshwm sim, nws tsis yog qhov teeb meem ntawm cov khoom poob xwb, tab sis kuj muaj kev hem thawj rau lub neej, tshwj xeeb tshaj yog rau cov ru tsev photovoltaic fais fab nroj tsuag. cov kab hauv qab." Ib tug qub tub rog nyob rau hauv lub tshav pob ntawm fais fab chaw nres tsheb peev hais tias.

Lwm tus neeg uas tau koom nrog hauv kev ua haujlwm thiab kev pabcuam ntawm cov chaw tsim hluav taws xob photovoltaic tau ntau xyoo ntxiv, "Kev nyab xeeb ntawm cov chaw tsim hluav taws xob yog qhov teeb meem uas tsis tuaj yeem tsis quav ntsej. Kev saib xyuas kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom kuj yog ib qho teeb meem uas lub kev lag luam yuav tsum ntsib thaum nws txav mus rau kev txhim kho zoo. "

Qhov tseeb, kev nyab xeeb thiab kev ntseeg siab kuj yog ib qho tseem ceeb ntawm kev txo cov nqi ntawm photovoltaic fais fab nroj tsuag. Nyob rau hauv 25- xyoo kev ua haujlwm ntawm photovoltaic fais fab nroj tsuag, nyob rau hauv lub ntsiab lus ntawm kev ua kom muaj kev nyab xeeb kev ua haujlwm, txo qhov kev pheej hmoo ntawm kev tsim hluav taws xob txo vim cov khoom lossis cov teeb meem hauv lub cev yog txoj hauv kev tseem ceeb los txo cov nqi thoob plaws hauv lub neej.

Kev pheej hmoo ntawm chaw nres tsheb fais fab tsis tuaj yeem tsis quav ntsej

Ntawm cov xwm txheej cuam tshuam txog kev tsim hluav taws xob poob, cov qauv snails thiab backplane defects yog cov saum toj kawg nkaus tsib hauv cov nqi tu. Raws li "phab ntsa tooj liab thiab phab ntsa hlau" ntawm photovoltaic modules, txawm hais tias lub nraub qaum muaj nyob rau hauv cov khoom siv hauv kev lag luam photovoltaic, nws lub luag haujlwm tsis tuaj yeem kwv yees. Thaum lub nraub qaum muaj cov kab nrib pleb, yellowing thiab lwm yam teeb meem, nws yuav tsis tsuas yog cuam tshuam ncaj qha rau lub zog tsim ntawm lub roj teeb module, tab sis kuj ua rau muaj teeb meem loj xws li hluav taws kub.

Qhov tseeb, cov teeb meem kev pheej hmoo coj los ntawm lub backplane kuj tau rov tshwm sim nyob rau hauv cov chaw nres tsheb fais fab loj loj, suav nrog ib zaug-nrov 3A backplane, thiab lwm yam, uas tau raug tshem tawm ntawm kev ua lag luam raws li kev pheej hmoo ntawm kev siv sab nraum zoov. Nyob rau hauv xyoo tas los no, tau tsav los ntawm kev txo nqi, kev lag luam photovoltaic tseem tab tom tshawb nrhiav cov thev naus laus zis rov qab tshiab, thiab PET backplane yog ib txoj hauv kev.

Qhov tseeb, ntau cov tuam txhab lag luam suav nrog Nyiv thiab Tuam Tshoj tau ua tiav txoj hauv kev no tom qab sim siv cov ntaub ntawv hloov PET polyester backsheets. Raws li cov kws tshaj lij, cov txheej txheem kev laus sab nraum zoov ntawm PET feem ntau yog cov duab-oxidation. Nyob rau hauv kev sib xyaw ua ke ntawm ultraviolet lub teeb thiab kub thiab av noo, PET absorbs ultraviolet lub teeb thiab undergoes Norrish degradation, thiab cov saw molecular yog tawg nyob ze ntawm ester pawg, uas ua rau poob ntawm txhua yam khoom thiab yellowing.

Cov txheej txheem kev laus ntawm PET txiav txim siab nws qhov kev ua tau zoo hauv kev siv hauv tsev. Daim duab 1 qhia lub chaw nres tsheb fais fab photovoltaic nyob hauv Inner Mongolia. Lub tshuab hluav taws xob siv PET backsheets. Tom qab 4 xyoo ntawm kev ua haujlwm, ze li ntawm 40 feem pua ​​​​ntawm cov ntaub ntawv rov qab yog cov xim daj. , ntau tshaj 10 feem pua ​​​​ntawm cov modules 'backplanes yog foamed thiab delaminated, thiab 1-5 feem pua ​​ntawm cov modules muaj teeb meem kub kub; cov monocrystalline modules nyob rau hauv daim duab 2 yog faib photovoltaic fais fab chaw nruab rau ntawm cov hlau corrugated ru tsev ntawm cov tsev lag luam. Cov khoom siv yog PET, thiab yellowing ntawm lub nraub qaum yog pom ntawm qhov muag liab qab. Qhov loj tshaj plaws cheeb tsam yog ntug ntawm lub module array. b * tus nqi yog siab npaum li 27. Ultraviolet rays ua kom cov ntug kev laus ntawm lub nraub qaum rov qab, uas ua rau cov txheej txheej sab nraud ntawm lub nraub qaum rov qab tawg thiab ua nkig.

Nws tau kawm los ntawm tus kws tshaj lij ntawm tus thawj coj ntawm lub tuam txhab lub taub hau uas cov ntawv PET ntshiab tsis tau siv rau hauv cov khoom xa los ntawm lub tuam txhab. Nws yog qhov tsim nyog rau qhov kub thiab txias, high-humidity thiab high-ultraviolet ib puag ncig, thiab kev ntseeg siab ntawm cov ntawv PET ntshiab tsis tau dhau qhov kev xav tau. "

Kev lag luam photovoltaic tab tom ntsib txoj kev hloov pauv ntawm kev loj hlob mus rau kev loj hlob zoo. Txawm hais tias nws yog qhov kev xav tau ntawm kev lag luam nws tus kheej, lossis qhov kev pheej hmoo loj ntawm ciam teb los ntawm photovoltaic hla ciam teb, kev siv cov khoom siv tau zoo thiab txhim khu kev qha tau dhau los ua "kab hauv qab" ntawm kev lag luam. Nws yog ib qho tseem ceeb kom paub txog kev nyab xeeb ntawm kev ua haujlwm ntawm photovoltaic fais fab nroj tsuag thiab txo cov nqi ntxiv
