Ntau lub tuam txhab hluav taws xob photovoltaic tau siv rau hauv thaj chaw toj siab, thiab qee qhov ntawm lawv tau muab faib ua cov khoom siv hluav taws xob.Kev faib tawm kuj yog tawg.Qhov xwm txheej no kuj nyuaj rau tswj.Txhawm rau txo cov nqi txij nkawm, txoj hauv kev zoo yog txhawm rau txhim kho kev ntseeg tau ntawm lub kaw lus, thiab qhov kev ntseeg siab ntawm qhov system nyob ntawm qhov kev ntseeg tau ntawm cov khoom siv hauv lub cev.

Cov khoom uas peb tau xyuam xim rau ntawm no tsis yog qhov tseem ceeb uas koj feem ntau pom, tab sis qhov me me xws li cov khoom sib txuas, cov khoom siv hluav taws xob tsawg,kab, thiab lwm yam. Cov ntsiab lus ntau dua, yuav ua rau muaj teeb meem ntau dua.Hnub no peb yuav txheeb xyuas qhovcov khoom sib txuas.

Connectors nyob txhua qhov chaw

Hauv kev tu txhua hnub ntawm photovoltaic fais fab nroj tsuag, cov cuab yeej tseem ceeb xws li cov khoom siv, DC fais fab faib khoom, thiab inverters yog cov khoom tseem ceeb ntawm kev txhawj xeeb.Qhov no yog qhov peb yuav tsum ua kom zoo li qub thiab ruaj khov, vim tias lawv muaj qhov ua tsis tau zoo thiab muaj kev cuam tshuam zoo tom qab ua tsis tiav.

Tab sis hauv qee qhov txuas, muaj qee qhov txhaum uas tib neeg tsis paub lossis tsis quav ntsej.Qhov tseeb, lawv twb tau poob lub zog tsim tawm yam tsis paub txog.Hauv lwm lo lus, qhov no yog qhov uas peb tuaj yeem ua kom muaj zog tsim hluav taws xob.Yog li cov cuab yeej twg cuam tshuam txog kev tsim hluav taws xob?

Muaj ntau qhov chaw hauv chaw nres tsheb fais fab uas xav tau kev sib tshuam.Cheebtsam, hlws ris thawv, inverters, combiner thawv, thiab lwm yam. tag nrho cov xav tau ib tug ntaus ntawv — connector.Txhua lub thawv sib txuas siv ib khub ntawm cov khoom sib txuas.Tus naj npawb ntawm txhua lub thawv sib xyaw ua ke muaj feem cuam tshuam nrog tus tsim.Feem ntau, 8 khub rau 16 khub yog siv, thaum inverters siv 2 khub rau 4 khub lossis ntau dua.Nyob rau tib lub sijhawm, qee tus naj npawb ntawm cov khoom sib txuas yuav tsum tau siv rau hauv kev tsim kho zaum kawg ntawm qhov chaw nres tsheb fais fab.

Nkaum tsis ua hauj lwm nquag tshwm sim

Lub connector yog me me, ntau qhov txuas yuav tsum tau siv, thiab tus nqi me me.Thiab muaj ntau lub tuam txhab uas tsim cov connector.Vim li no, ob peb tus neeg tau mloog zoo rau kev siv cov khoom sib txuas, yuav ua li cas yog tias nws siv tau zoo, thiab yog tias nws tsis siv zoo, yuav ua li cas thiaj li tshwm sim.Txawm li cas los xij, tom qab kev nkag mus rau hauv qhov tob thiab nkag siab, nws pom tias nws yog qhov tseeb vim tias cov khoom no thiab cov kev sib tw hauv qhov txuas no yog chaotic heev.

Ua ntej tshaj plaws, peb pib tshawb xyuas los ntawm daim ntawv thov davhlau ya nyob twg.Txij li thaum muaj ntau qhov kev sib txuas hauv qhov chaw nres tsheb fais fab yuav tsum tau siv cov khoom sib txuas, peb tuaj yeem pom cov khoom siv ntawm ntau yam khoom sib txuas ntawm qhov chaw, xws li cov thawv sib txuas, cov thawv sib txuas, cov khoom sib txuas, cov cables, thiab lwm yam, cov khoom sib txuas yog qhov zoo sib xws.Cov khoom siv no yog cov khoom tseem ceeb ntawm lub chaw nres tsheb fais fab.Qee lub sij hawm muaj xwm txheej, tib neeg keeb kwm xav tias nws yog ib qho teeb meem nrog lub thawv sib txuas lossis cov khoom siv nws tus kheej.Tom qab kev tshawb nrhiav, nws tau pom tias nws muaj feem xyuam nrog lub connector.

Piv txwv li, yog hais tias lub connector ntes hluav taws, ntau tus tswv yuav yws txog cov khoom, vim hais tias ib qho kawg ntawm lub connector yog cov khoom ntawm nws tus kheej, tab sis qee zaus nws yog tshwm sim los ntawm lub connector.

Raws li kev txheeb cais, cov teeb meem cuam tshuam los ntawm cov khoom sib txuas muaj xws li: nce kev tiv thaiv kev tiv thaiv, hluav taws xob tsim hluav taws xob ntawm lub connector, luv luv lifespan, hluav taws kub ntawm lub connector, burnout ntawm lub connector, lub hwj chim tsis ua hauj lwm ntawm cov hlua Cheebtsam, tsis ua hauj lwm ntawm lub junction box, thiab tivthaiv to, thiab lwm yam, uas tuaj yeem ua rau lub cev tsis ua haujlwm, cov khoom rov qab los, kev puas tsuaj hauv Circuit Court, rov ua dua thiab kho dua tshiab yuav ua rau poob ntawm cov khoom tseem ceeb thiab cuam tshuam rau lub zog tsim hluav taws xob ntawm lub chaw nres tsheb fais fab, thiab qhov loj tshaj plaws yog hluav taws kub.

Piv txwv li, kev tiv thaiv kev tiv thaiv yuav loj dua, thiab kev sib cuag ntawm lub connector ncaj qha cuam tshuam rau lub zog tsim hluav taws xob ntawm lub chaw nres tsheb fais fab.Yog li ntawd, "tsis muaj kev tiv thaiv" yog qhov yuav tsum tau muaj rau cov khoom siv hluav taws xob photovoltaic.Tsis tas li ntawd, kev tiv thaiv siab heev kuj tseem tuaj yeem ua rau lub connector kom sov thiab ua rau hluav taws kub tom qab overheating.Qhov no kuj yog qhov ua rau muaj teeb meem kev nyab xeeb hauv ntau lub tshuab hluav taws xob photovoltaic.

Tracing rov qab mus rau lub hauv paus ntawm cov teeb meem no, thawj yog lub installation ntawm lub hwj chim chaw nres tsheb nyob rau hauv lub kawg theem.Kev tshawb nrhiav pom tias ntau lub chaw nres tsheb fais fab muaj teeb meem nrog kev ua haujlwm ntawm qee qhov kev sib txuas thaum lub sijhawm ua haujlwm nrawm rau lub sijhawm tsim kho, uas ncaj qha tso zais qhov phom sij rau kev ua haujlwm tom ntej ntawm lub chaw nres tsheb fais fab.

Cov pab pawg tsim kho lossis EPC cov tuam txhab ntawm qee qhov chaw nres tsheb loj hauv av nyob rau sab hnub poob muaj kev nkag siab tsis txaus ntawm cov khoom sib txuas, thiab muaj ntau yam teeb meem kev teeb tsa.Piv txwv li, lub txiv ntseej-hom connector xav tau cov cuab yeej tshaj lij rau kev ua haujlwm pabcuam.Raws li kev ua haujlwm raug, cov txiv ntoo ntawm lub connector tsis tuaj yeem screwed mus rau qhov kawg.Yuav tsum muaj qhov sib txawv ntawm li 2 hli thaum lub sijhawm ua haujlwm (qhov sib txawv yog nyob ntawm txoj kab uas hla sab nraud).Tightening cov txiv ntoo mus rau qhov kawg yuav ua rau kev sib khi ua haujlwm ntawm cov khoom sib txuas.

Nyob rau tib lub sijhawm, muaj teeb meem hauv crimping, qhov tseem ceeb tshaj plaws yog tias cov cuab yeej crimping tsis yog kev tshaj lij.Qee cov neeg ua haujlwm ntawm qhov chaw ncaj qha siv cov khoom siv tsis zoo lossis cov cuab yeej dav dav rau crimping, uas yuav ua rau tsis zoo crimping, xws li khoov ntawm tooj liab ntawm qhov sib koom ua ke, tsis ua haujlwm ntawm crimping qee cov xov tooj tooj liab, tsis raug nias rau cable rwb thaiv tsev, thiab lwm yam. ntawm cov neeg pluag crimping yog ncaj qha ntsig txog kev nyab xeeb ntawm lub hwj chim chaw nres tsheb.

Lwm qhov kev ua tau zoo yog vim qhov muag tsis pom kev ntawm kev teeb tsa kev ua haujlwm, ua rau txo qis qhov zoo ntawm crimping.Yog tias qhov chaw tsim kho tsis tuaj yeem lav qhov zoo ntawm txhua qhov crimping thiaj li ua haujlwm nrawm, ua ke nrog kev siv cov cuab yeej tsis zoo yuav ua rau muaj teeb meem ntau dua.

Cov kev txawj ntse ntawm cov installers lawv tus kheej muaj kev cuam tshuam rau theem ntawm kev sib txuas ntawm kev sib txuas.Vim li no, cov tuam txhab tshaj lij hauv kev lag luam qhia tias yog cov cuab yeej tshaj lij thiab cov txheej txheem ua haujlwm raug siv, qhov zoo ntawm qhov project yuav raug txhim kho.

Qhov teeb meem thib ob yog tias ntau yam khoom sib txuas yog siv hauv kev tsis meej pem.Cov khoom sib txuas ntawm cov npe sib txawv yog txuas rau ib leeg.Cov thawv sib txuas, cov thawv sib txuas, thiab cov khoom siv hluav taws xob tag nrho siv cov khoom sib txuas ntawm cov hom sib txawv, thiab kev sib txuam ntawm cov khoom sib txuas tsis suav nrog txhua.

Tus neeg sau xov xwm tau xam phaj ntau tus tswv chaw nres tsheb fais fab thiab EPC cov tuam txhab, thiab nug seb lawv puas paub txog cov khoom sib txuas, thiab thaum twg cov khoom sib txuas muaj teeb meem, lawv cov lus teb tau poob tag nrho.Kev ua haujlwm thiab kev saib xyuas cov neeg ua haujlwm ntawm cov chaw nres tsheb loj hauv av tau hais tias: "Tus neeg muag khoom txuas tau tshaj tawm tias nws tuaj yeem txuas rau ib leeg, thiab nws tuaj yeem txuas rau MC4."

Nws tau nkag siab tias cov lus tawm tswv yim los ntawm cov tswv thiab kev ua haujlwm thiab cov neeg ua haujlwm saib xyuas yog qhov tseeb.Tam sim no, txhua yam khoom siv hluav taws xob photovoltaic yuav tshaj tawm rau lawv cov neeg siv khoom tias lawv tuaj yeem txuas nrog MC4.Yog vim li cas MC4?

Nws tau tshaj tawm tias MC4 yog cov khoom siv sib txuas.Cov chaw tsim khoom yog Swiss Stäubli Multi-Contact (feem ntau hu ua MC hauv kev lag luam), nrog rau kev lag luam feem ntau tshaj 50% los ntawm 2010 txog 2013. MC4 yog ib qho qauv hauv lub tuam txhab cov khoom lag luam, uas paub zoo txog nws. dav thov.

Yog li, lwm yam khoom lag luam txuas ntawm lub khw tuaj yeem txuas nrog MC4?

Hauv kev xam phaj, Hong Weigang, tus thawj coj ntawm lub tuam tsev photovoltaic ntawm Stäubli Multi-Contact, tau muab cov lus teb meej: "Ib feem ntau ntawm cov teeb meem ntawm cov khoom sib txuas yog los ntawm kev sib koom ua ke.Peb yeej tsis pom zoo tias cov khoom sib txuas ntawm cov npe sib txawv yog sib koom ua ke thiab sib koom ua ke.Nws kuj tsis tso cai.Cov kev sib txuas ntawm cov npe sib txawv tsis tuaj yeem sib koom ua ke, thiab kev tiv thaiv kev tiv thaiv yuav nce ntxiv yog tias ua haujlwm li ntawd.Lub cev ntawv pov thawj kuj tau hais tias kev sib koom ua ke tsis raug tso cai, thiab tsuas yog cov khoom lag luam ntawm tib lub koob los ntawm tib lub chaw tsim khoom raug tso cai rau kev sib koom ua ke.MC cov khoom tuaj yeem sib koom ua ke thiab ntsaws thiab sib xws. "

Ntawm qhov teeb meem no, peb sab laj ob lub tuam txhab ntawv pov thawj, TüV Rheinland thiab TüV Sab Qab Teb Lub Tebchaws Yelemees, thiab cov lus teb yog tias cov khoom sib txuas ntawm cov npe sib txawv tsis tuaj yeem sib koom ua ke.Yog tias koj yuav tsum siv nws, nws yog qhov zoo tshaj los ua qhov kev sim ua ntej.Xu Hailiang, Tus Thawj Coj ntawm TüV SÜD Photovoltaic Department, tau hais tias: "Qee qhov ntawm cov khoom siv imitation connectors muaj tib tus qauv tsim, tab sis cov khoom siv hluav taws xob sib txawv, thiab cov khoom tseem ceeb sib txawv.Muaj ntau qhov teeb meem tau tshwm sim hauv qhov kev xeem sib tw tam sim no.Los ntawm kev sim, cov tswv ntawm lub chaw nres tsheb fais fab tuaj yeem kawm paub ntau ntxiv txog cov teeb meem ua ntej, piv txwv li, tom qab siv mus ntev, yuav muaj kev tsis sib haum xeeb hauv ib puag ncig hnyav yav tom ntej."Nws tau hais tias cov tswv cuab thiab cov chaw nres tsheb fais fab yuav tsum ua tib zoo saib xyuas cov khoom siv thiab cov ntaub ntawv pov thawj, thiab tom qab ntawd txiav txim siab seb yuav xaiv cov khoom siv li cas.

"Qhov xwm txheej zoo tshaj plaws yog siv tib txheej ntawm cov khoom lag luam los ntawm tib lub tuam txhab nyob rau hauv tib array, tab sis feem ntau cov chaw nres tsheb fais fab muaj ntau tus neeg xa khoom txuas.Seb cov connectors no tuaj yeem sib phim yog qhov txaus ntshai zais.Piv txwv li, lub chaw nres tsheb fais fab muaj qhov sib txuas ntawm MC, RenHe, thiab Kev Tiv Thaiv Ceev, txawm tias peb lub tuam txhab lav cov khoom lag luam zoo, lawv tseem yuav tsum xav txog qhov teeb meem ntawm kev sib cuam tshuam.Txhawm rau txo qhov kev pheej hmoo ntau npaum li qhov ua tau, ntau lub tuam txhab thiab qee qhov chaw nres tsheb fais fab tub ua lag luam tau thov kom muaj kev sib tw sib tw.Raws li Zhu Qifeng, tus thawj coj muag khoom ntawm TüV SÜD photovoltaic khoom department, Zhang Jialin, tus thawj coj muag khoom ntawm TüV Rheinland photovoltaic department, kuj pom zoo.Nws tau hais tias Rheinland tau ua ntau qhov kev sim, thiab txij li pom muaj teeb meem, kev sib raug zoo tsis pom zoo.

"Yog tias qhov kev tiv thaiv loj dhau lawm, lub connector yuav ntes hluav taws, thiab kev tiv thaiv siab yuav ua rau lub connector hlawv tawm, thiab cov khoom ntawm cov hlua yuav raug txiav tawm.Tsis tas li ntawd, ntau lub tuam txhab hauv tsev vam khom rau kev sib txuas nyuaj thaum txhim kho, uas ua rau lub interface kom sov, thiab cov kab hluav taws xob muaj teeb meem., Qhov kub yuam kev nce mus txog 12-20 degrees. "Shen Qianping, tus kws tshaj lij cov khoom lag luam hauv lub tuam tsev photovoltaic ntawm Stäubli Multi-Contact, tau taw qhia qhov teeb meem loj heev.

Nws tau tshaj tawm tias MC yeej tsis tau nthuav tawm qhov ua siab ntev ntawm nws cov khoom.Nyob rau hauv lwm yam lus, feem ntau ntawm cov photovoltaic connectors nyob rau hauv kev ua lag luam yog raws li nyob rau hauv kev soj ntsuam ntawm MC4 cov qauv los tsim lawv tus kheej cov khoom tolerances.Txawm hais tias muaj kev cuam tshuam ntawm kev tswj hwm ntau lawm, kev kam rau siab ntawm ntau yam khoom sib txawv.Muaj kev phom sij zais zoo thaum cov khoom sib txuas ntawm cov hom sib txawv tau txuas rau ib leeg, tshwj xeeb tshaj yog nyob rau hauv cov chaw nres tsheb loj uas siv cov khoom sib txuas ntau dua.

Tam sim no, muaj kev tsis sib haum xeeb loj hauv cov khoom sib txuas thiab cov tuam txhab sib txuas sib txuas hauv kev lag luam hais txog qhov teeb meem ntawm kev sib koom ua ke.Ib tug ntau ntawm domestic connector thiab junction box tuam txhab uas muag tau hais tias cov khoom ntawm txawv hom tau dhau qhov kev xeem ntawm lub tuam txhab soj ntsuam thiab tsis muaj kev cuam tshuam.

Vim tias tsis muaj cov qauv kev sib koom ua ke, cov qauv ntawm cov ntawv pov thawj thiab cov tuam txhab kuaj hauv kev lag luam tsis zoo ib yam.Intertek muaj qee qhov sib txawv nrog t ü V Rhine, Nande thiab UL hauv qhov teeb meem ntawm kev sib txuas ntawm kev sib koom ua ke.Raws li Cheng Wanmao, tus thawj coj ntawm pab pawg photovoltaic ntawm Intertek, ntau qhov teeb meem tsis tau pom nyob rau hauv qee qhov kev sib tw tam sim no.Txawm li cas los xij, raws li qib kev muaj kev txhawj xeeb, ntxiv rau qhov teeb meem tsis kam, muaj qhov teeb meem ntawm arcing.Yog li ntawd muaj qhov tsis txaus ntseeg hauv kev sib txuas thiab sib txuas ntawm cov khoom sib txuas.

Qhov teeb meem thib peb yog cov tuam txhab tsim khoom sib txuas sib xyaw ua ke, thiab ntau lub tuam txhab me me thiab txawm tias kev cob qhia koom nrog.Kuv pom qhov tshwm sim lom zem hauv qhov kev tshawb fawb.Ntau lub tuam txhab txuas hauv tsev hu lawv tus kheej cov khoom sib txuas yog MC4.Lawv xav tias qhov no yog lub ntsiab lus dav dav rau cov khoom sib txuas hauv kev lag luam.Kuj tseem muaj cov tuam txhab lag luam uas txawm tawm ntawm cov khoom cuav thiab luam tawm lub logo ntawm MC tuam txhab ncaj qha.

"Thaum cov khoom cuav no tau cim nrog MC lub tuam txhab logo raug coj rov qab rau kev sim, peb xav tias nyuaj heev.Ntawm qhov tod tes, peb txaus siab rau peb cov khoom sib qhia thiab kev muaj koob meej.Ntawm qhov tod tes, peb yuav tsum tau nrog ntau yam teeb meem cuav, thiab nws kuj yog tus nqi qis. "Raws li MC Hong Weigang, raws li MC lub ntiaj teb tam sim no muaj peev xwm tsim tau ntawm 30-35GW, qhov ntsuas tau raug txo kom siab, thiab kev tswj tus nqi tau ua tiav zoo heev.“Tab sis vim li cas lawv tseem qis dua peb?Peb pib los ntawm kev xaiv cov khoom siv, cov khoom siv thev naus laus zis, cov txheej txheem tsim khoom, cov cuab yeej tsim khoom, kev tswj xyuas zoo thiab lwm yam kev soj ntsuam.Lub realization ntawm tus nqi qis feem ntau txi ntau yam.Kev siv cov ntaub ntawv xa rov qab mus rau theem nrab tam sim no yog ib qho yuam kev hauv kev txo tus cwj pwm.Kev sib tw nqi qis zoo li no yog qhov tseeb yooj yim hauv kev txuas nrog kev txiav cov ces kaum thiab cov khoom siv.Raws li kev lag luam photovoltaic muaj kev txhawj xeeb, kev txo nqi yog ib qho kev ua haujlwm tas mus li thiab nyuaj.Txhua yam ntawm kev lag luam tau ua haujlwm nyuaj, xws li kev txhim kho kev hloov pauv kev ua haujlwm, nce qhov system voltage, thiab kev cuam tshuam cov khoom tsim.Kev nce qib ntawm automation, thiab lwm yam. Tab sis tib lub sij hawm txo cov nqi thiab tsis txhob txo cov khoom zoo yog lub hauv paus ntsiab lus uas yuav tsum tau ua raws li. "

Shen Qianping ntawm MC Lub Tuam Txhab tau hais ntxiv tias: "Cov luam tawm kuj xav tau thev naus laus zis.MC muaj Multiam Technology watchband technology (patented thev naus laus zis), uas tuaj yeem tsis tsuas yog xyuas kom meej tias qhov kev sib cuag ntawm lub connector yog tsawg heev, tab sis kuj muaj kev tiv thaiv tsis tu ncua.Nws tseem tuaj yeem suav thiab tswj tau.Ntau npaum li cas tam sim no ntws thiab tiv thaiv kev tiv thaiv tuaj yeem suav tau.Qhov kev tiv thaiv ntawm ob lub ntsiab lus sib tiv tauj tuaj yeem txheeb xyuas kom paub seb qhov chaw ntau npaum li cas rau dissipate cua sov, thiab xaiv cov khoom sib txuas tsim nyog raws li cov neeg siv khoom xav tau.Cov cuab yeej siv pluaj yuav tsum muaj qee cov txheej txheem nyuaj, uas yog imitated heev.Imitated sawv daws yuav yooj yim deform.Qhov no yog cov cuab yeej cuab tam ntawm lub tuam txhab Swiss, thiab kev nqis peev thiab tus nqi ntawm cov khoom tsim nws tus kheej tsis tuaj yeem muab piv rau. "

4 lab kWh hauv 25 xyoo

Nws yog to taub hais tias nws yog ib qho tseem ceeb yuav tsum tau rau connectors kom tsis txhob muaj kev sib cuag tsis kam, thiab ntau lub tuam txhab nyob rau hauv kev lag luam tau pib ua li ntawd, tab sis nyob rau hauv lub sij hawm ntev stability thiab tsis tshua muaj kev sib cuag kuj yuav tsum tau ntau ruaj khov technology tsub zuj zuj thiab R & D kev them nyiaj yug, nruam ntev- Lub sij hawm ruaj khov thiab tsis tshua muaj kev sib cuag Resistance tsis tsuas yog ua tau zoo guarantees cov kev ua haujlwm ib txwm muaj ntawm cov kev sib txuas me me ntawm lub chaw nres tsheb fais fab, tab sis kuj tsim cov txiaj ntsig tsis xav txog rau lub chaw nres tsheb fais fab.

Ntau npaum li cas qhov kev tiv thaiv ntawm PV connector cuam tshuam rau kev ua tau zoo ntawm PV lub zog tsim hluav taws xob?Hong Weigang xam qhov no.Ua ib qho 100MW PV project ua piv txwv, nws muab piv rau kev sib cuag ntawm MC PV connector (nruab nrab 0.35m Ω) nrog qhov siab tshaj plaws tiv thaiv ntawm 5m Ω teev nyob rau hauv tus txheej txheem thoob ntiaj teb en50521.Piv nrog rau qhov kev tiv thaiv siab, kev tiv thaiv qis dua ua rau PV system ua haujlwm tau zoo Txog 160000 kwh ntau hluav taws xob tsim txhua xyoo, thiab txog 4 lab kwh ntau hluav taws xob tsim tawm hauv 25 xyoo.Nws tuaj yeem pom tau tias cov txiaj ntsig kev lag luam coj los ntawm kev sib cuag tsis tu ncua yog qhov tseem ceeb heev.Xav tias kev tiv thaiv kev tiv thaiv ntau dua yog qhov ua rau tsis ua haujlwm, xav tau ntau qhov hloov pauv thiab sijhawm saib xyuas ntau dua, uas txhais tau tias tus nqi kho ntau dua.

"Nyob rau hauv lub neej yav tom ntej, kev lag luam yuav muaj kev tshaj lij, thiab yuav muaj ntau thiab ntau qhov sib txawv ntawm kev sib txuas lub thawv tsim thiab cov khoom sib txuas.Cov qauv kev sib txuas thiab cov qauv sib txuas yuav raug txhim kho ntxiv hauv lawv txoj haujlwm, thiab cov khoom siv hauv txhua qhov txuas ntawm cov saw hlau yuav raug txhim kho, "hais Hong WeingGang.Ntawm chav kawm, thaum kawg, cov tuam txhab uas xav tau lub sijhawm ntev yuav tau them nyiaj rau cov khoom siv nws tus kheej, cov txheej txheem, qib tsim khoom thiab hom.Nyob rau hauv cov nqe lus ntawm cov khoom nws tus kheej, ob qho tib si txawv teb chaws cov ntaub ntawv tooj liab thiab domestic tooj liab cov ntaub ntawv yog tooj liab cov ntaub ntawv nrog tib lub npe, tab sis lub ntsiab ratios nyob rau hauv lawv yog txawv, uas ua rau sib txawv nyob rau hauv kev ua tau zoo ntawm lub Cheebtsam.Yog li ntawd, peb yuav tsum kawm thiab khaws cia ntev. "

Vim tias cov khoom sib txuas yog "me me", tus tsim hluav taws xob tam sim no thiab lub tuam txhab EPC tsis tshua xav txog qhov sib txuam ntawm cov khoom sib txuas thaum tsim thiab tsim lub chaw nres tsheb fais fab;tus neeg muag khoom tivthaiv kuj them me ntsis rau cov khoom sib txuas thaum xaiv lub thawv sib txuas;Cov tswv tsev fais fab thiab cov neeg ua haujlwm tsis muaj txoj hauv kev nkag siab txog qhov cuam tshuam ntawm cov khoom sib txuas.Yog li ntawd, muaj ntau yam kev phom sij zais ua ntej qhov teeb meem raug nthuav tawm hauv thaj chaw loj.

Photovoltaic backplanes, PID hnub ci hlwb, kuj yog kev lag luam cov xim tom qab qhov teeb meem tshwm sim.Nws cia siab tias qhov sib txuas tuaj yeem nyiam cov xim ua ntej qhov teeb meem tshwm sim hauv thaj chaw loj, thiab tiv thaiv qhov teeb meem ua ntej nws tshwm sim.
