Hauv kaum xyoo tom ntej no, lub ru tsev photovoltaics yuav dhau los ua kev noj txhua hnub. Thaum koj lub ru tsev tuaj yeem dhau los ua khoom muag, koj puas paub nws "photovoltaic Performance index"?
Ib qho kev ntsuas hu ua "Sun Number" yuav qhia koj lub ru tsev twg yog qhov zoo tshaj plaws rau kev teeb tsa PV.
Cov nyiaj pab los ntawm US Department of Energy's SunShot Grant, Sun Number, powered by NREL, yog tam sim no nyob, muab "photovoltaic Performance index" ntawm ntau tshaj 84 lab ru tsev nyob rau hauv North America.
Qhov "Photovoltaic Index" muaj nyob ntawm 0 mus rau 100, thiab tag nrho cov qhab nia suav nrog plaub tus qhab nia rau cov ru tsev. Cov khoom sib tw suav nrog cov cuab yeej ntawm lub tsev ru tsev, kev nyab xeeb hauv cheeb tsam, tus nqi hluav taws xob hauv cheeb tsam, thiab tus nqi ntawm kev teeb tsa photovoltaic hauv cheeb tsam. Txhua pawg yog qhov hnyav sib txawv nyob ntawm seb nws cuam tshuam li cas rau qhov haum ntawm PV ru tsev.
1. Roof photovoltaic zog
Tau qhab nia ntawm qhov siab tshaj plaws ntawm 80, pawg no suav nrog feem ntau ntawm tag nrho PV Performance index thiab ntsuas seb tus qauv ntawm lub tsev puas haum rau lub hnub ci zog.
Lub ru tsev PV cov qhab nia suav nrog kev ntsuas ntawm lub ru tsev qhov sib txawv, lub ru tsev orientation, lub ru tsev cheeb tsam, lub ru tsev shading, thiab lwm yam. Qhov zoo tshaj plaws, lub ru tsev PV yuav tsum tau nruab rau ntawm lub ru tsev sab qab teb nrog rau thaj tsam uas sib npaug ntawm qhov chaw nyob ntawm lub tsev, thiab tsis muaj qhov ntxoov ntxoo.
Qhov tseeb yog tias ob peb lub ru tsev ua tau raws li tag nrho cov qauv no. Tsis txaus siab tsis tau txhais hais tias nws tsis zoo, nws tsuas yog txhais tau hais tias nws yuav cuam tshuam rau lub zog tsim hluav taws xob ntawm lub photovoltaic system los yog xav tau kev tsim ntau dua.
Sun Number siv daim duab 3D los txiav txim seb lub ru tsev zoo li cas rau cov "zoo meej" thiab ua rau cov qhab nia ru tsev. Feem ntau, cov ru tsev uas xav kom nruab photovoltaic yuav tsum muaj cov qhab nia photovoltaic tsis tsawg dua 50, thaum lub ru tsev haum rau kev teeb tsa photovoltaic feem ntau muaj cov qhab nia siab dua 60, thiab cov qhab nia ntawm lub ru tsev zoo siab tshaj 70.
2. Cov qhab nia hauv cheeb tsam huab cua
Qhov qhab nia siab tshaj plaws rau cov khoom no yog 8. Lub hnub ci ntaus lub ru tsev ntawm lub tsev yuav cuam tshuam ncaj qha rau cov hluav taws xob uas tsim los ntawm cov hnub ci vaj huam sib luag. Sun Number coj qhov no mus rau hauv tus account los ntawm preset regional climate scores, siv cov ntaub ntawv hnub ci irradiance los ntawm National Renewable Energy Laboratory (NREL).
Qhov ntau lub hnub ci ib cheeb tsam tau txais, qhov siab dua nws cov qhab nia Regional Climate Score. Lub hnub ci irradiance tau txais tsis yog tsuas yog cuam tshuam rau qhov ntev, tab sis kuj tseem cuam tshuam nrog qhov siab hauv zos, huab cua huab cua Performance index, huab cua txhua xyoo, dej nag, thiab lwm yam. Piv txwv li, thaj chaw uas muaj cua daj cua dub heev yuav muaj qee yam cuam tshuam rau lub teeb, tab sis kev tu cov nyhuv ntawm lub ru tsev photovoltaics yuav txhim kho, uas yog zoo dua li cov cheeb tsam uas nquag muaj huab cua thiab lub teeb los nag.
3. Cov qhab nias hluav taws xob
Qhov qhab nia siab tshaj plaws rau cov khoom no yog 8. Sun Number xam cov nqi hluav taws xob nruab nrab rau cheeb tsam. Hauv thaj chaw uas cov nqi hluav taws xob siab, kev txhim kho PV tuaj yeem txuag cov tswv nyiaj ntau dua. Tus nqi hluav taws xob nruab nrab no tsis yog tsuas yog cuam tshuam nrog tus nqi hluav taws xob tus qauv hauv cheeb tsam, tab sis kuj tseem siv rau hauv tus account qhov kev siv hluav taws xob ntawm cov tswv. Piv txwv li, rau cov nqi hluav taws xob siab tshaj plaws thiab cov nqi hluav taws xob peak-valley tus nqi ntawm cov hluav taws xob muaj hluav taws xob, rau cov tswv tsev, qhov kev cuam tshuam ntawm cov nqi hluav taws xob theem. Feem ntau, tus nqi hluav taws xob ntau dua, qhov qhab nia ntawm cov nqi hluav taws xob ntau dua, uas txhais tau tias tsim nyog rau kev txhim kho photovoltaics.
Xav txog kev txhawb nqa photovoltaic cov cai ntawm thaj chaw sib txawv thiab lub teb chaws, cov nyiaj pab txhawb zog kuj tuaj yeem raug txiav txim siab thaum xam qhov ntsuas no.
4. PV Installation Tus Nqi Them Nqi
Qhov qhab nia siab tshaj plaws rau cov khoom no yog 4. Hnub Naj Npawb kuj tseem siv rau hauv tus nqi ntawm lub hnub ci kev teeb tsa hauv zos, tab sis cov nqi ua rau qhov tsawg tshaj plaws ntawm cov qhab nia tag nrho. Kev teeb tsa tus nqi sib txawv heev, tsis yog tsuas yog cuam tshuam nrog lub ru tsev, tab sis kuj rau thaj chaw hauv cheeb tsam, tus nqi tsim kho, lub ru tsev, thiab lwm yam. Cov ntaub ntawv muaj zog yog xav tau los txhawb nws, thiab nws tseem tuaj yeem muab tus nqi siv rau cov tswv hauv zos. kom tsis txhob poob rau hauv tus nqi qis. nqe ntxiab.
5. Rooftop PV Index Total Score
Plaub yam khoom ntxiv ntxiv mus rau qhov siab tshaj plaws ntawm 100 cov ntsiab lus. Txawm hais tias qhov qhab nia zoo tshaj ntawm 100 yog qhov qhab nia zoo tshaj plaws, txhua qhov PV Index saum toj 70 txhais tau tias PV yuav yog qhov tsim nyog peev rau cov cuab yeej.
Txawm li cas los xij, yog tias qhov ntsuas hluav taws xob photovoltaic tsis zoo, nws tsis txhais hais tias nws tsis muaj nuj nqis rau nruab ru tsev photovoltaic. Muaj ntau yam uas cuam tshuam rau lub zog tsim hluav taws xob ntawm lub ru tsev photovoltaic systems, thiab qee zaum kev tsim qauv zoo tuaj yeem ntxiv cov ntsiab lus rau lub ru tsev photovoltaic Performance index. Piv txwv li, qhov zoo tshaj plaws orientation tsim, qhov zoo tshaj plaws inclination tsim, qhov zoo tshaj plaws installation kom muaj nuj nqis, thiab lwm yam.
Tebchaws Europe thiab Tebchaws Meskas yeej ib txwm ua tau zoo rau kev tsim cov qauv kev ntsuas ntau raws li cov cuab yeej siv thoob ntiaj teb, thiab cov neeg Suav tau siv sijhawm los ntsuas cov xwm txheej tshwj xeeb raws li kev paub dhau los. Yog tias koj yog ib lub koom haum tsim qauv, koj puas xav tsim thiab siv cov cuab yeej ntsuas no?
