Ib pawg ntawm cov kws tshawb fawb los ntawm University of Natural Resources thiab Life Sciences hauv Austria tau muab piv rau kev ntsuas lub neej ntawm txoj kab ntsug bifacial.agrivoltaic systemsnrog cov stilted agrivoltaics chaw nyob rau hauv-tob soj ntsuam tag nrho.
Nyob rau hauv lub thib ob systems, lub panels yog stilted los ntawm hauv av rau ib tug steel qauv, thiab kev ua liaj ua teb zus tau tej cov nyob rau hauv qab. Hauv thawj qhov kev teeb tsa, cov modules raug xa mus rau cov qauv ntsug thiab kev ua liaj ua teb yog ua los ntawm cov kab modules.
Qhov kev ntsuam xyuas suav nrog ob qhov xwm txheej siv mono-siv ntawm thaj av arable - kev ua liaj ua teb tsis hloov pauv thiab tag nrho kev hloov pauv ntawm kev ua liaj ua teb nrog PV panels. "Thaum ntsuas kev ua liaj ua teb nrog kev sib koom ua ke nws yog qhov tsim nyog yuav tsum suav tag nrho cov qoob loo hloov pauv, txij li cov qoob loo raws li agrivoltaic systems yuav tsum ua tsis tau tsuas yog rau ib lub caij, tab sis rau praxis cov sij hawm cuam tshuam," cov kws tshawb fawb tau teev tseg. "Qhov no txhais tau hais tias yuav npog cov qoob loo uas tuaj yeem rov ua dua thiab yog tus sawv cev rau qhov nruab nrab Austrian ntau lawm."
Kev xaiv qoob loo hloov pauv rau kev tshawb fawb yog qab zib beet, lub caij ntuj no hom qoob mog, taum pauv, thiab lub caij ntuj no hom qoob mog. "Green manure yog xav tias yuav tsum tau cog ua ntej qab zib beet thiab soybean ntau lawm, ntsig txog, los tiv thaiv cov av los ntawm nitrogen los ntawm leaching thiab ua rau nws siv tau rau cov qoob loo hauv qab no," pab pawg piav qhia.
Kev ntsuas lub neej yog ua raws li cov qauv thoob ntiaj teb ISO 14040 thiab 14044.
Cov kws tshawb fawb tau hais tias lawv qhov kev tshuaj xyuas tau pom tias cov kab ke ntsug bifacial muaj qhov cuam tshuam ib puag ncig qis dua piv rau cov kab ke stilted hauv txhua qhov kev soj ntsuam cuam tshuam. Qhov no tau ua tiav ua tsaug rau kev siv cov khoom siv qis dua rau cov qauv mounting thiab qhov cuam tshuam qis ntawm cov iav-iav modules piv rau cov iav ntawv ci.
Lawv kuj pom tau hais tias ob qho tib si agrivoltaic systems ua rau txo qis kev cuam tshuam ib puag ncig hauv peb ntawm cuaj qhov kev ntsuam xyuas qhov cuam tshuam. "Txoj kev tshawb fawb no qhia tau hais tias kev tsim hluav taws xob PV yog qhov laj thawj tseem ceeb rau kev cuam tshuam ib puag ncig hauv agrivoltaic systems, thaum kev ua liaj ua teb yog qhov tseem ceeb," cov kws tshawb fawb tau hais. "Agrivoltaic systems piv tau zoo rau kev kawm lwm txoj kev xaiv nrog kev tsom mus rau ib qho hluav taws xob lossis kev ua liaj ua teb."
Lawv qhov kev tshawb pom tau qhia hauv kev tshawb fawb "Environmental life cycle assessment of a stilted and vertical bifacial crop-based agrivoltaic multi av-siv system thiab kev sib piv nrog mono av-siv av ua liaj ua teb," luam tawm hauvRenewable and Sustainable Energy Reviews.
