Bifacialphotovoltaics tam sim no yog ib qho kev nyiam hauv hnub ci zog.Txawm hais tias ob-sided panels tseem kim dua li cov vaj huam sib luag ib sab, lawv ua kom muaj zog ntau dua qhov tsim nyog.Qhov no txhais tau tias them rov qab sai dua thiab txo tus nqi hluav taws xob (LCOE) rau cov phiaj xwm hnub ci.Qhov tseeb, ib txoj kev tshawb fawb tsis ntev los no tau pom tias kev teeb tsa bifacial 1T (piv txwv li, bifacial solar arrays mounted ntawm ib lub axis tracker) tuaj yeem ua kom muaj zog ntau dua 35% thiab ncav cuag tus nqi qis tshaj plaws ntawm hluav taws xob (LCOE) hauv ntiaj teb rau cov neeg feem coob ( 93.1% ntawm thaj av).Cov lej no zoo li yuav txhim kho raws li cov nqi tsim khoom txuas ntxiv mus zuj zus thiab kev ua tau zoo tshiab hauv cov thev naus laus zis tau tshawb pom.
      Bifacial solar modules muaj ntau yam zoo dua li cov hnub ci vaj huam sib luag vim tias hluav taws xob tuaj yeem tsim los ntawm ob sab ntawm ob sab ntawm lub teeb ci, yog li ua kom tag nrho lub zog tsim los ntawm lub cev (txog 50% hauv qee kis).Qee cov kws tshaj lij kwv yees tias kev lag luam bifacial yuav loj hlob kaum npaug hauv plaub xyoos tom ntej.Hnub no tsab xov xwm yuav tshawb xyuas seb bifacial PV ua haujlwm li cas, cov txiaj ntsig ntawm cov thev naus laus zis, qee qhov kev txwv, thiab thaum twg koj yuav tsum (thiab yuav tsum tsis txhob) xav txog lawv rau koj lub hnub ci.
Cias muab, bifacial hnub ci PV yog lub hnub ci module uas absorbs lub teeb los ntawm ob sab ntawm lub vaj huam sib luag.Thaum lub vaj huam sib luag "ib leeg ib sab" muaj cov khoom, opaque npog ntawm ib sab, ib lub ntsej muag ob sab nthuav tawm ob sab pem hauv ntej thiab sab nraub qaum ntawm lub hnub ci.
      Raws li qhov xwm txheej, bifacial solar panels muaj peev xwm ua kom muaj zog ntau dua li cov hnub ci vaj huam sib luag.Qhov no yog vim hais tias ntxiv rau lub hnub ci ncaj qha rau ntawm qhov chaw module, lawv tau txais txiaj ntsig los ntawm lub teeb pom kev, diffuse lub teeb thiab albedo irradiance.
      Tam sim no peb tau tshawb xyuas qee qhov txiaj ntsig ntawm bifacial solar panels, nws yog ib qho tseem ceeb kom nkag siab tias vim li cas lawv tsis ua rau txhua qhov haujlwm.Vim tias lawv cov nqi nce ntxiv ntawm cov hnub ci vaj huam sib luag ib sab, koj yuav tsum xyuas kom meej tias koj lub kaw lus tuaj yeem ua kom zoo dua ntawm cov txiaj ntsig ntawm kev teeb tsa bifacial.Piv txwv li, ib txoj hauv kev pheej yig tshaj plaws thiab yooj yim tshaj plaws los tsim lub hnub ci hnub ci niaj hnub no yog coj kom zoo dua ntawm lub ru tsev sab qab teb uas twb muaj lawm thiab txhim kho ntau li ntau tau recessed panels li sai tau.Lub kaw lus zoo li no txo ​​qis racking thiab installation nqi thiab pab koj pib tsim hluav taws xob yam tsis muaj daim kab xev liab ntau dhau los yog tso cai.Hauv qhov no, ob-sided modules yuav tsis tsim nyog.Vim hais tias cov modules tau mounted ze rau lub ru tsev, tsis muaj chaw txaus rau lub teeb mus rau sab nraum qab ntawm panels.Txawm tias muaj lub ru tsev ci ntsa iab, yog tias koj mount ib lub hnub ci vaj huam sib luag nyob ze ua ke, tseem tsis muaj chaw rau kev xav.Ua ntej pib koj qhov project, koj yuav tsum txiav txim siab seb hom kev teeb tsa thiab kev tsim qauv tsim nyog rau koj cov cuab yeej tshwj xeeb, qhov chaw, thiab koj lub lag luam 'kev xav tau ntawm tus kheej.Feem ntau, qhov no tuaj yeem suav nrog ob sab hnub ci vaj huam sib luag, tab sis muaj qhov xwm txheej tiag tiag uas tus nqi ntxiv tsis muaj txiaj ntsig.
      Pom tseeb, zoo li txhua qhov project hnub ci, kev tsim ntawm lub kaw lus yuav nyob ntawm ntau yam sib txawv.Ib sab hnub ci vaj huam sib luag tseem muaj qhov chaw thiab yuav tsis mus qhov twg ntev.Qhov ntawd tau hais tias, ntau tus ntseeg tias peb nyob hauv lub sijhawm tshiab ntawm PV qhov chaw ua haujlwm siab ua haujlwm tau zoo tshaj plaws thiab kev siv tshuab bifacial yog ib qho piv txwv tseem ceeb ntawm kev ua kom lub zog loj npaum li cas tuaj yeem ua tiav siv cov ntaub ntawv zoo dua."Bifacial modules yog lub neej yav tom ntej ntawm kev lag luam," said Hongbin Fang, technical director of Longi Leye."Nws tau txais tag nrho cov txiaj ntsig ntawm monocrystalline PERC modules: siab zog ceev rau qhov tseem ceeb BOS txuag, siab zog tawm los, zoo dua lub teeb ua haujlwm thiab qis qis coefficient.Tsis tas li ntawd, bifacial PERC modules tseem sau lub zog ntawm sab nraub qaum, uas qhia tias muaj zog ntau dua.Peb ntseeg tias bifacial PERC modules yog txoj hauv kev zoo tshaj plaws kom ua tiav LCOE qis dua. "Tsis tas li ntawd, muaj ntau lub hnub ci PV thev naus laus zis uas muaj txiaj ntsig ntau dua li cov vaj huam sib luag bifacial, tab sis lawv cov nqi tseem siab heev uas lawv tsis ua rau ntau qhov haujlwm.Cov piv txwv pom tseeb tshaj plaws yog lub hnub ci kev teeb tsa nrog lub dual-axis tracker.Dual-axis trackers tso cai rau lub hnub ci teeb tsa kom txav mus los, sab laug thiab sab xis (raws li lub npe cuam tshuam) txhawm rau taug qab lub hnub txoj kev thoob plaws hnub.Txawm li cas los xij, txawm hais tias lub zog siab tshaj plaws tau ua tiav hauv tus tracker, tus nqi tseem siab dhau los ua kom pom tseeb qhov ntau lawm.Thaum muaj ntau yam kev tsim kho tshiab yuav tsum tau ua nyob rau hauv lub hnub ci teb, bifacial solar panels zoo li yog cov kauj ruam tom ntej, vim tias lawv muaj peev xwm ua kom muaj zog ntau dua piv rau qhov tsis tshua muaj nqi ntawm cov vaj huam sib luag.
