1 Dab tsi yog ob-sided photovoltaic module?
Bifacial Photovoltaic Modules yog ib hom photovoltaic module uas tuaj yeem siv tib lub sijhawm siv ob qho tib si pem hauv ntej thiab sab nraub qaum. Tsis zoo li cov khoom siv hluav taws xob ib leeg-ib sab photovoltaic uas tsuas tuaj yeem siv lub hnub ci teeb meem ntawm sab xub ntiag, ob sab photovoltaic modules tsis tuaj yeem siv ncaj qha hnub ci hluav taws xob los ntawm sab xub ntiag, tab sis kuj tseem muaj kev cuam tshuam thiab tawg lub teeb los ntawm sab nraum qab, yog li txhim kho tag nrho photoelectric conversion efficiency. .
Cov yam ntxwv ntawm cov qauv thiab kev ua haujlwm ntawm ob sab photovoltaics:
Tsim qauv nta:Ob sab pem hauv ntej thiab sab nraub qaum ntawm ob sab photovoltaic module yog nruab nrog cov cell photovoltaic, uas feem ntau siv cov khoom siv hluav taws xob zoo ib leeg lossis polycrystalline silicon hlwb. Lub vaj huam sib luag sab nraub qaum feem ntau yog pob tshab (xws li iav lossis pob tshab polymer) kom tso cai rau lub teeb hla thiab nqus los ntawm lub roj teeb nyob tom qab. Kev tsim hluav taws xob rov qab ntawm cov roj teeb ob sab ua kom muaj txiaj ntsig zoo ntawm cov duab hluav taws xob nyob rau sab nraub qaum, feem ntau siv Back Contact (IBC) thev naus laus zis lossis cov khoom siv hluav taws xob ib nrab pob tshab.
Txoj haujlwm ua haujlwm:Cov hlwb zoo photovoltaic nqus cov hnub ci ncaj qha thiab hloov mus rau hauv hluav taws xob hluav taws xob, uas yog lub luag haujlwm tseem ceeb ntawm tag nrho cov photovoltaic modules.
Lub nraub qaum photovoltaic cell absorbs lub teeb pom los ntawm hauv av, ib puag ncig ib puag ncig, thiab cov tsev, nrog rau lub teeb tawg los ntawm lub ntuj. Cov rays ntawm lub teeb no yog absorbed los ntawm lub roj teeb nyob tom qab thiab hloov mus rau hauv hluav taws xob lub zog.
Qhov zoo ntawm ob sab photovoltaics: nce lub zog tsim thiab kev ua haujlwm zoo
Ob chav sided photovoltaic modules tuaj yeem siv ntau lub teeb pom kev zoo, tshwj xeeb tshaj yog nyob rau hauv qhov chaw muaj kev cuam tshuam hauv av xws li daus, xuab zeb, thiab lub ru tsev dawb, uas tuaj yeem ua rau muaj zog ntau ntxiv.
Tag nrho photoelectric conversion efficiency ntawm ob-sided photovoltaic modules yog siab dua li ntawm ib sab modules vim hais tias lawv muaj peev xwm nqus tau thiab siv ntau lub teeb. Lub photoelectric conversion efficiency nyob rau sab nraum qab yog 60% -90% ntawm uas nyob rau hauv pem hauv ntej, thiab lub zog tsim tau tom qab kev koom ua ke system yog hais txog 4% -30% piv rau ib leeg-sided tivthaiv fais fab nroj tsuag.
Kev teeb tsa thiab kev siv ob sab photovoltaic
① Kev teeb tsa hauv av:
Hauv av mounted systems, ob-sided photovoltaic modules tuaj yeem siv lub teeb pom kev zoo los ntawm hauv av, thiab feem ntau ua haujlwm zoo tshaj plaws ntawm qhov chaw muaj kev cuam tshuam siab xws li xuab zeb dawb, nyom, thiab lwm yam.
② Kev teeb tsa lub tsev:
Hauv kev teeb tsa lub ru tsev, tshwj xeeb tshaj yog rau lub ru tsev dawb lossis lub teeb xim, qhov kev xav ntawm lub teeb los ntawm lub nraub qaum yog qhov muaj zog, thiab ob-sided photovoltaic modules tuaj yeem ua tiav lub zog ntau dua.
③ Vertical installation:
Hauv qee daim ntawv thov tshwj xeeb, xws li laj kab, guardrails, lossis lub tsev sib xyaw photovoltaics (BIPV), ob sab photovoltaic modules tuaj yeem ntsia tau ntsug, siv lub teeb pom kev los ntawm ob sab.
④ Taug qab qhov system:
Ob-sided photovoltaic modules tau nruab rau ntawm lub hnub ci taug qab qhov system tuaj yeem ua kom tau txais lub teeb pom kev zoo thoob plaws hnub thiab ua kom tag nrho lub zog tsim.
2 Yuav ua li cas tsim, nruab, thiab tswj ob sab photovoltaic modules hauv photovoltaic fais fab nroj tsuag
Albedo:Xaiv cov khoom siv hauv av zoo xws li cov pob zeb dawb, xuab zeb, nyom, lossis cov chaw coated nrog cov coatings los txhim kho kev siv cov teeb pom kev zoo.
Qhov sib txawv ntawm qhov sib txawv:Tsim kom muaj qhov sib txawv ntawm qhov sib txawv kom tsis txhob muaj kev cuam tshuam ntawm cov khoom thiab xyuas kom lub nraub qaum tuaj yeem tau txais lub teeb pom kev txaus.
Mounting kaum sab xis:Xaiv qhov tsim nyog qaij lub kaum sab xis thiab txoj kev teeb tsa kom ua tiav qhov kev txais tos ntawm lub teeb los ntawm ob sab pem hauv ntej thiab nraub qaum ntawm ob sab photovoltaic module.
Backboard xaiv:Siv cov ntaub ntawv pob tshab lossis semi pob tshab backplate, xws li ob chav iav cov qauv, kom ntseeg tau tias lub teeb rov qab tuaj yeem dhau los ntawm lub roj teeb thiab nqus tau.
Inverter xaiv:Xaiv ib qho inverter uas phim rau ob sab photovoltaic module los xyuas kom meej tias lub kaw lus muaj peev xwm ua tau zoo tam sim no los ntawm ob sab pem hauv ntej thiab sab nraub qaum.
Tsim nyog npaj cov cables kom tsis txhob thaiv lub teeb nraub qaum, thaum xyuas kom cov cables tsis tsim cov duab ntxoov ntxoo ntxiv. Thaum ob-sided photovoltaic modules nqus lub teeb los ntawm sab nraub qaum, lawv tuaj yeem tsim cov cua sov ntxiv, thiab tsim kom muaj cua sov thiab cua kub dissipation system yog xav tau kom tsis txhob overheating ntawm cov modules.
Ob chav sided photovoltaic installation thiab txij nkawm
Ob chav sided photovoltaic modules muaj cov yam ntxwv ntawm kev tsim hluav taws xob ob sab, thiab lub tshuab hluav taws xob photovoltaic siv ob sab photovoltaic modules. Ua ntej, nws yog ib qho tsim nyog los npaj ob-sided photovoltaic modules ntawm lub kaum sab xis zoo. Qhov siab dua qhov siab ntawm cov khoom siv, lub zog ntxiv yuav raug tsim tawm, tab sis qhov siab ntawm lub installation yuav tsum tsis pub tshaj 2 meters; Thiab raws li lub kaum sab xis inclination nce, qhov cuam tshuam hluav taws xob tau txais los ntawm sab nraub qaum ntawm ob sab ntawm cov khoom tsis muaj zog. Xyuas kom muaj kev txhim kho thiab kev tsim kho kom zoo, tsis txhob khawb los yog kev sib kis ntawm qhov chaw ntawm cov khoom, tshwj xeeb tshaj yog nyob rau sab nraub qaum, kom tsis txhob cuam tshuam lub teeb xa hluav taws xob thiab kev tiv thaiv kev ua haujlwm.
Kev tu tsis tu ncua:Tsis tu ncua ntxuav lub hauv ntej thiab nram qab ntawm ob sab photovoltaic modules kom tsis txhob muaj plua plav, noog poob, los yog lwm yam kuab paug cuam tshuam rau lub teeb kis tau tus mob thiab module efficiency.
Kev soj ntsuam thiab kuaj pom:Siv lub kaw lus saib xyuas los saib xyuas lub sijhawm ua haujlwm ntawm lub sijhawm ua haujlwm ntawm ob sab photovoltaic system, tshawb xyuas tam sim thiab daws qhov tsis raug, thiab xyuas kom lub sijhawm ua haujlwm tau zoo ntawm lub system.
Environmental Impact Assessment:Tsis tu ncua ntsuas qhov cuam tshuam ntawm ib puag ncig kev hloov pauv ntawm ob sab photovoltaic systems, xws li kev loj hlob ntawm cov nroj tsuag, kev sib sau ntawm cov daus, cov plua plav, thiab lwm yam., thiab kho cov tswv yim kho kom raws sijhawm.
Kev lag luam zeem muag
Nrog rau kev nce qib ntawm cov thev naus laus zis thev naus laus zis thiab kev xav tau ntau ntxiv rau cov kev daws teeb meem photovoltaic hauv kev ua lag luam, daim ntawv thov ntawm ob sab photovoltaic modules tau dhau los ua ntau thiab dav. Nws cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo thiab ntau yam kev thov ua rau nws muaj peev xwm loj hlob hauv kev lag luam photovoltaic yav tom ntej.
Ob chav sided photovoltaic modules ua tiav lub zog tsim hluav taws xob ntau dua thiab dav siv cov xwm txheej los ntawm kev siv cov khoom siv lub teeb los ntawm ob sab pem hauv ntej thiab nraub qaum, txhawb kev txhim kho ntxiv ntawm kev lag luam photovoltaic.
