Ib pab neeg tshawb fawb los ntawm Purdue University tau pomAgrivoltaic System muaj peev xwm ua kom muaj zog ntau lawm thiab txo cov pa roj carbon emissions thaum muaj kev cuam tshuam tsawg rau cov qoob loo.
Hauv daim ntawv tshawb fawb "Kev muaj peev xwm ntawm photovoltaics ntawm thaj av ua liaj ua teb: PV puas tuaj yeem daws cov zaub mov vs roj sib cav?", muaj nyob hauvPhau ntawv Journal of Cleaner Production, pab pawg tau tshuaj xyuas tsib qhov xwm txheej uas muaj cov pob kws cog qoob loo hauv thaj av nruab nrab ntawm Tebchaws Meskas.
Thawj qhov yog qhov xwm txheej hauv paus, nrog cov pob kws loj hlob thoob plaws cheeb tsam. Qhov thib ob nta ib txwm hnub ci nruab rau ntawm 25% ntawm thaj chaw, hloov cov qoob loo pob kws. Lwm qhov xwm txheej peb muaj xws li agrivoltaics nrog cov pob kws loj hlob hauv qab lawv, nrog kwv yees li 5.5% ntawm thaj av nyob los ntawm cov qauv hnub ci thiab tsis muaj rau cov qoob loo loj hlob. Lub vaj huam sib luag hnub ci tag nrho yog siv nyob rau hauv lub system thib peb, ua raws li ib nrab thiab ib lub hlis vaj huam sib luag ntom hauv lub thib plaub thiab tsib lub cim.
Cov kws tshawb fawb tau muab piv rau tsib lub tshuab no hla plaub qhov kev ntsuas: kev tsim cov pob kws siv los ua zaub mov lossis tsiaj pub, kev tsim hluav taws xob hauv daim ntawv bioethanol lossis hluav taws xob, txo qis cov pa hluav taws xob hauv tsev cog khoom thiab cov txiaj ntsig rau cov neeg ua liaj ua teb.
Kev tsim khoom noj khoom haus / khoom noj siab tshaj plaws tau ua tiav nyob rau hauv lub hauv paus system. Lub kaw lus thib ob pom cov pob kws ua zaub mov / pub poob los ntawm 25%, nyob rau hauv kev faib ua feem rau qhov txo qis hauv av muaj. Cov txiaj ntsig tau los ntawm cov tshuab agrivoltaic sib txawv raws li thaj chaw ntxoov ntxoo, nrog rau 11% txo cov pob kws muaj rau cov khoom noj / cov khoom noj uas tau sau tseg hauv lub quarter solar vaj huam sib luag qhov ntom ntom thaum piv rau lub hauv paus system.
Thaum piv rau lub hauv paus system, cov tsoos photovoltaic system thiab lub quarter-density agrivoltaic system tsa qhov kawg-siv zog tsim los ntawm tsawg dua 2 MWh / ha / xyoo mus rau kwv yees li 140 MWh MWh / ha / xyoo. Ib nrab-density agrivoltaic system tau tsa lub zog tsim tawm mus txog 280 MWh / ha / xyoo thiab tag nrho-density agrivoltaic system tsa lub zog tsim tawm mus txog 560 MW / ha / xyoo.
Cov kws tshawb fawb kuj pom tias ethanol muaj qhov cuam tshuam tsawg kawg nkaus rau tag nrho cov khoom siv hluav taws xob hauv tshuab ob txog tsib. "Yog li ntawd, tsis muaj qhov sib txawv tseem ceeb ntawm tag nrho cov khoom siv hluav taws xob thaum txiav txim siab qhov qis qis qis thiab siab ntxoov ntxoo yield ciam teb ntawm pob kws ntau lawm," said team.
Thaum xam qhov txo qis hauv tsev cog khoom, cov txheej txheem hauv paus, tsuas yog ethanol ua lub zog, tau txo qis dua 2 tonnes CO2-eq/ha/xyoo. Lwm cov tshuab tau txo qis emissions los ntawm ntau pua tonnes CO2-eq/ha/xyoo, nrog rau qhov muaj nyob rau hauv txhua "zoo ib yam li cov hnub ci vaj huam sib luag uas tau muab tso rau hauv tag nrho cheeb tsam kev kho mob".
Thaum cov tsoos photovoltaic system thiab cov agrivoltaic system nrog ib lub quarter ceev tau zoo tib lub zog tsim thiab txo cov roj tsev cog khoom, cov ntaub ntawv tshawb fawb kwv yees cov pob kws ntau dua rau cov agrivoltaic system vim nws tso cai rau ntau cov qoob loo loj hlob thiab shading raug txo los ntawm qhov sib txawv loj ntawm. vaj huam sib luag.
Nyob rau hauv tsab ntawv ceeb toom xaus, cov kws tshawb fawb hais tias agrivoltaics "tuaj yeem muab lub tswv yim siv tau los ua kom yooj yim rau kev lag luam tam sim no ntawm kev tsim hluav taws xob, kev tso pa tawm hauv tsev cog khoom, khoom noj khoom haus, thiab kev ua liaj ua teb tau txais txiaj ntsig."
"Peb qhov kev soj ntsuam qhia tau hais tias ob qho tib si photovoltaic systems thiab agrivoltaics tuaj yeem ua kom muaj zog ntau lawm ib hectare txheeb ze rau lub hauv paus uas nyob ib ncig ntawm 27% ntawm pob kws yog ntaus nqi rau ethanol," cov kws tshawb fawb tau sau tseg.
Cov kws tshawb fawb tseem piav qhia tias thaum kev xa tawm ntawm agrivoltaics tuaj yeem cuam tshuam los ntawm cov nqi peev siab, qhov teeb meem no tuaj yeem kov yeej nrog kev txhawb nqa txoj cai, tshwj xeeb tshaj yog thaum cov nqi qoob loo tsis hloov pauv. Lawv hais tias cov nqi cuam tshuam yuav tsum txo qis thaum cov thev naus laus zis txhim kho, tab sis ceeb toom tias yuav tsum ua haujlwm ntau ntxiv kom ntseeg tau tias muaj kev nkag siab zoo ntawm cov neeg koom nrog kev xav tau thiab txhim kho engineering kom txo qis cov nqi thaum ua kom cov txiaj ntsig zoo tshaj plaws.
"Kev koom ua ke photovoltaics rau hauv av ua liaj ua teb muaj peev xwm ntau dua rau kev tsim hluav taws xob txuas ntxiv thiab txo cov pa hluav taws xob hauv tsev cog khoom," daim ntawv hais. "Peb cov kev suav suav qhia tias yog tias tsis muaj ethanol xav tau cov pob kws muaj khoom noj thiab tsiaj pub tsiaj tuaj yeem nce ntxiv txawm tias cov hnub ci vaj huam sib luag sib xyaw ua ke, piv rau cov nyiaj muaj nyob rau hauv cov xwm txheej ntawm ethanol xav tau thiab tsis muaj kev sib koom ua ke ntawm photovoltaic. Hauv qhov kev pom no, agrivoltaic thev naus laus zis muab cov kev daws teeb meem zoo rau cov zaub mov piv rau roj sib cav, tso cai rau ntau lub zog tsim tawm nrog qhov cuam tshuam me me rau pob kws ua zaub mov / khoom noj.
