Taw Qhia Rau Cov Khoom Siv Tseem Ceeb Thiab Cov Khoom Ntawm Hnub Ci Photovoltaic Modules
May 20, 2024
Hnub ci photovoltaic modules, tseem hu ua hnub ci modules thiab photovoltaic modules, yog tsim los ntawm ib tug series ntawm solar cells teem nyob rau hauv sib txawv arrays. Ib lub hnub ci vaj huam sib luag tsis tuaj yeem siv ncaj qha los ua lub zog hluav taws xob. Txhawm rau ua kom lub zog siv hluav taws xob, ob peb lub hlwb yuav tsum tau txuas nrog hauv cov koob, sib luag thiab nruj nreem kaw rau hauv cov khoom. Hnub ci photovoltaic modules (tseem hu ua solar panels) yog lub hauv paus tseem ceeb ntawm lub hnub ci hluav taws xob tsim hluav taws xob thiab qhov tseem ceeb tshaj plaws ntawm lub hnub ci hluav taws xob tsim hluav taws xob. Nws txoj haujlwm yog hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob, lossis xa mus rau lub roj teeb cia, lossis txhawb nqa kev ua haujlwm.
Cov ntaub ntawv tseem ceeb thiab cov khoom ntawm hnub ci photovoltaic modules
Photovoltaic iav:Lub vaj huam sib luag iav siv nyob rau hauv lub roj teeb module yog cov hlau tsis muaj ultra-dawb suede tempered iav. Qhov dav dav yog 3.2mm thiab 4mm. Lub tsev cov khoom siv hnub ci vaj huam sib luag qee zaum siv iav tempered nrog lub thickness ntawm 5 ~ 10mm, tab sis tsis hais txog ntawm thickness, lub teeb transmittance yuav tsum siab tshaj 90%. Tsawg-hlau ultra-dawb txhais tau hais tias cov ntsiab lus hlau ntawm hom iav no qis dua li cov iav zoo tib yam, yog li ua rau lub teeb xa hluav taws xob ntawm iav. Nyob rau tib lub sijhawm, thaum saib ntawm ntug ntawm iav, hom iav no kuj yog xim dawb dua li iav zoo tib yam, uas yog ntsuab dua thaum saib ntawm ntug. Kev kho tempering yog ua kom lub zog ntawm iav, tiv thaiv qhov cuam tshuam ntawm cua, xuab zeb thiab lawg, thiab ua lub luag haujlwm ntev hauv kev tiv thaiv lub hnub ci. Tom qab tempering lub iav vaj huam sib luag, lub zog ntawm lub iav tuaj yeem nce los ntawm 3 mus rau 4 npaug piv nrog cov iav zoo tib yam.
EVA zaj duab xis:Ib copolymer ntawm ethylene thiab yas acetate, nws yog ib qho thermosetting zaj duab xis zoo li kub yaj nplaum thiab tam sim no yog ib qho khoom siv nplaum siv hauv hnub ci cell module ntim. Ob txheej ntawm EVA zaj duab xis yog ntxiv rau lub hnub ci cell module. Ob txheej ntawm EVA zaj duab xis yog sandwiched ntawm lub vaj huam sib luag iav, hlwb thiab TPT backsheet zaj duab xis los khi cov iav, hlwb thiab TPT ua ke. Tom qab nws raug khi rau iav, nws tuaj yeem ua rau lub teeb xa hluav taws xob ntawm iav, ua lub luag haujlwm tiv thaiv kev cuam tshuam, thiab tau txais lub zog tso tawm ntawm lub hnub ci cell module.
Cov ntaub ntawv rov qab:Cov ntaub ntawv rov qab ntawm lub hnub ci cell module tuaj yeem xaiv ntau txoj hauv kev raws li kev siv sib txawv ntawm lub hnub ci cell module. Feem ntau, muaj ob peb hom xws li tempered iav, organic iav, txhuas alloy, TPT puas zaj duab xis, thiab lwm yam. Lub tempered iav backsheet yog tsuas yog siv los ua ob-sided lub teeb-transmitting lub tsev khoom siv hnub ci cell modules, uas yog siv rau photovoltaic curtains. phab ntsa, photovoltaic ru tsev, thiab lwm yam. Tus nqi yog siab dua thiab cov module hnyav kuj hnyav. Tsis tas li ntawd, feem ntau siv tam sim no yog TPT zaj duab xis sib xyaw. TPT composite daim nyias nyias muaj cov yam ntxwv ntawm airtightness, zoo zog, zoo huab cua tsis kam, ntev kev pab cuam lub neej, tsis muaj kev hloov ntawm lamination kub, thiab muaj zog sib txuas nrog cov ntaub ntawv nplaum.
Cov yam ntxwv no haum rau ntim cov hnub ci cell modules. Raws li cov ntaub ntawv rov qab ntawm lub roj teeb module, nws zoo tiv thaiv kev yaig thiab cuam tshuam ntawm ntau yam xov xwm, tshwj xeeb tshaj yog dej, oxygen, corrosive gases, thiab lwm yam, ntawm EVA thiab hnub ci hlwb. Ntxiv nrog rau TPT, cov ntaub ntawv sib xyaw ua ke muaj xws li cov yeeb yaj kiab sib xyaw nrog cov yeeb yaj kiab hlau sandwich hauv nruab nrab, xws li TAT (cov yeeb yaj kiab sib xyaw ntawm Tedlar zaj duab xis thiab txhuas zaj duab xis) thiab TIT (cov yeeb yaj kiab sib xyaw ntawm Tedlar zaj duab xis thiab hlau zaj duab xis). Cov yeeb yaj kiab sib xyaw no kuj muaj cov yam ntxwv ntawm lub zog siab, nplaim taws retardancy, durability, thiab kev tu tus kheej. Cov yeeb yaj kiab dawb sib xyaw kuj tuaj yeem cuam tshuam lub hnub ci, uas tuaj yeem txhim kho kev hloov pauv ntawm cov khoom siv roj teeb. Nws kuj tseem muaj qhov cuam tshuam zoo ntawm cov kab hluav taws xob infrared, uas tuaj yeem txo cov nqi ntawm cov khoom siv roj teeb. Kev khiav hauj lwm kub nyob rau hauv lub hnub muaj zog.
hlws ris lub thawv thiab bypass diode
Qhov tshwj xeeb hlws ris lub thawv rau lub hnub ci cell modules yog ib qho khoom siv uas txuas cov khoom siv hluav taws xob sab hauv ntawm lub roj teeb module rau sab nraud. Cov tsheb npav zoo thiab tsis zoo uas tau kos los ntawm lub roj teeb vaj huam sib luag nkag mus rau hauv lub thawv sib txuas thiab tau txuas los yog txuas rau cov haujlwm sib txuas hauv lub thawv sib txuas. Cov hlau lead tseem txuas nrog lub thawv sib txuas los ntawm kev ntsaws, vuam thiab ntsia hlau crimping. Kuj tseem muaj qhov chaw rau bypass diode installation nyob rau hauv lub hlws ris lub thawv los yog ib tug bypass diode yog ntsia ncaj qha.
Kev paub yooj yim ntawm cov khoom siv hnub ci cell
Thaum muaj ntau lub hnub ci cell modules txuas nrog hauv series los tsim cov roj teeb array lossis ib ceg ntawm lub roj teeb array, diodes yuav tsum tau txuas nrog rov qab ua ke ntawm qhov zoo thiab qhov tsis zoo tso tawm kawg ntawm txhua lub hnub ci vaj huam sib luag. Lub diode txuas nyob rau hauv parallel ntawm ob kawg ntawm lub module yog hu ua bypass diode. txoj kev diode.
Kev ua haujlwm ntawm bypass diode yog los tiv thaiv ib qho kev tiv thaiv lossis ib feem ntawm cov khoom siv hauv cov square array txoj hlua los ntawm kev thaiv los ntawm tus duab ntxoov ntxoo los yog malfunctioning thiab nres lub zog tsim. Ib tug pem hauv ntej bias voltage yuav tsim nyob rau ntawm ob kawg ntawm lub bypass diode ntawm cov khoom ua rau lub diode coj. Kev khiav hauj lwm tam sim no ntawm txoj hlua tivthaiv bypasses lub faulty tivthaiv thiab ntws los ntawm diode bypass, uas tsis cuam tshuam rau lub zog tsim ntawm lwm yam ib txwm Cheebtsam. Nws kuj tseem tiv thaiv cov khoom hla dhau los ntawm kev puas tsuaj los ntawm kev siab siab rau pem hauv ntej los yog cua sov vim "cov nyhuv kub kub".
Cell
Crystalline silicon hnub ci hlwb tau muab faib ua monocrystalline silicon cells thiab polycrystalline silicon cells. Qhov voltage ntawm txhua lub xov tooj yog li ntawm 0.5V. Cov ntsiab lus tseem ceeb yog 125mm × 125mm, tam sim no yog hais txog 5-6A, thiab lub zog yog li 2.5-3W; 156mm × 156mm Tam sim no yog hais txog 8-9A, lub zog yog li ntawm 4-5W, thiab lub thickness feem ntau yog 170 ~ 220um. Muaj cov xim xiav los tiv thaiv kev cuam tshuam ntawm lub xov tooj ntawm tes thiab ib daim phiaj nyiaj-dawb electrode. Muaj ntau cov kab nyias nyias, uas yog cov coj los ntawm cov electrodes ntawm lub xov tooj mus rau cov kab loj loj. Ob txoj kab nyiaj dawb-dawb yog cov kab loj loj, tseem hu ua cov kab hluav taws xob lossis cov electrodes sab saud. Kuj tseem muaj ob lub nyiaj-dawb daim phiaj tseem ceeb nyob rau sab nraum qab ntawm lub xov tooj ntawm tes, hu ua qis electrode lossis rov qab electrode. Kev sib txuas ntawm cov roj teeb hlwb yog ua tiav los ntawm kev sib txuas ntawm cov kab sib txuas mus rau cov kab hluav taws xob loj. Feem ntau, cov kab hluav taws xob nyob rau pem hauv ntej yog cov kab hluav taws xob tsis zoo ntawm cov roj teeb, thiab cov kab hluav taws xob nyob sab nraub qaum yog cov kab hluav taws xob zoo ntawm cov roj teeb. Lub cheeb tsam ntawm tes yog ncaj qha proportional rau cov zis tam sim no thiab lub zog tsim. Qhov loj dua qhov chaw, qhov ntau dua qhov tso zis tam sim no thiab lub zog tsim hluav taws xob.
