Hauv tsab xov xwm no, peb yuav tshawb xyuas seb yuav tsum muaj pes tsawg lub hnub ci vaj huam sib luag rau 10 kW system, dab tsi cuam tshuam rau lub hnub ci vaj huam sib luag, thiab qhov tseem ceeb ntawm cables thiab xov hlau hauv lub hnub ci kev teeb tsa.
Nkag siab Cov Ntsiab Lus: Dab tsi yog a10 kW Hnub Ci System?
Lub hnub ci 10 kW yog hais txog tag nrho cov hluav taws xob hluav taws xob uas lub kaw lus tuaj yeem tsim nyob rau hauv cov xwm txheej zoo. Lub "kW" sawv cev rau kilowatt, uas yog ib chav tsev ntawm lub zog. Lub zog 10 kW tuaj yeem tsim hluav taws xob 10 kW ib hourraws li lub hnub ci zoo, txhais tau hais tias thaum lub hnub ci siab tshaj plaws, nws yuav tsim hluav taws xob li 10, 000 watts.
Lub zog tsim los ntawm lub hnub ci vaj huam sib luag nyob ntawm ntau yam:
Lub peev xwm ntawm lub hnub ci vaj huam sib luag ( ntsuas hauv watts ib lub vaj huam sib luag)
Lub hnub ci teev muaj nyob rau hauv qhov chaw
Lub efficiency ntawm cov panels
Lub kaw lus poob, uas suav nrog lub zog poob thaum sib kis thiab hloov pauv
Rau 10 kW system, nws yog ib qho tseem ceeb los txiav txim seb cov hnub ci vaj huam sib luag yuav tsum tau ua kom tiav cov txiaj ntsig no, suav nrog cov ntsiab lus hais saum toj no.
Cov xwm txheej cuam tshuam txog pes tsawg lub vaj huam sib luag xav tau rau 10 kW
Muaj ntau ntau yam uas cuam tshuam rau ntau npaum li cas hnub ci vaj huam sib luag koj xav tau rau 10 kW hnub ci system:
1. Vaj huam sib luag Wattage
Hnub ci vaj huam sib luag tuaj nyob rau hauv ntau qhov kev ntsuas wattage, uas xa mus rau lub zog ntawm lub vaj huam sib luag tuaj yeem tsim tau raws li qhov kev pom zoo. Feem ntau cov vaj huam sib luag hnub ci vaj huam sib luag muaj wattages xws li 250 watts txog 400 watts ib lub vaj huam sib luag.
Piv txwv li:
Yog tias koj siv 300-watt hnub ci vaj huam sib luag, txhua lub vaj huam sib luag yuav tsim hluav taws xob 300 watts hauv qab hnub ci siab tshaj.
Yog tias koj siv 350-watt panels, txhua lub vaj huam sib luag yuav tsim 350 watts.
Qhov siab dua qhov wattage ntawm txhua lub vaj huam sib luag, cov vaj huam sib luag tsawg dua koj yuav xav tau kom ua tiav tib lub zog tso tawm.
Txhawm rau xam tus naj npawb ntawm cov vaj huam sib luag xav tau rau 10 kW system, koj tuaj yeem siv cov qauv no:
Tus lej ntawm Vaj Huam Sib Luag =System Loj (hauv watts) / Vaj Huam Sib Luag Wattage (hauv watts)
Rau 10 kW system siv 300-watt panels:
Tus lej ntawm Vaj Huam Sib Luag =10, 000 watts / 300 watts ib lub vaj huam sib luag =33.33 vaj huam sib luag
Yog li, koj yuav xav tau txog 34 panels kom ua tiav 10 kW ntawm lub zog.
Rau 350-watt panels:
Tus lej ntawm Vaj Huam Sib Luag =10, 000 watts / 350 watts ib lub vaj huam sib luag =28.57 vaj huam sib luag
Yog li, koj yuav xav tau kwv yees li 29 panels.
2. Solar vaj huam sib luag Efficiency
Kev ua tau zoo yog feem pua ntawm cov hnub ci uas lub hnub ci vaj huam sib luag tuaj yeem hloov mus ua hluav taws xob siv tau. Kev ua haujlwm siab dua txhais tau tias muaj hluav taws xob ntau dua ib square meter ntawm qhov chaw, thiab yog li tsawg dua panels xav tau rau ib qho system loj.
Monocrystalline panels feem ntau yog qhov ua tau zoo tshaj plaws, nrog kev ntsuas kev ua haujlwm ntawm 18% thiab 22%.
Polycrystalline panels tsis tshua muaj txiaj ntsig, feem ntau ntawm 15% mus rau 18%.
Nyias-film panels yog qhov tsawg tshaj plaws, nrog kev ua tau zoo ntawm 10% thiab 13%.
Cov vaj huam sib luag ua haujlwm siab dua, thaum kim dua, tuaj yeem txo tag nrho cov vaj huam sib luag uas xav tau rau 10 kW system.
3. Qhov chaw thiab Hnub Ci Sijhawm
Koj qhov chaw nyob ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab ntau npaum li cas lub hnub ci vaj huam sib luag tuaj yeem tsim tau. Lub hnub ci koj cheeb tsam tau txais txhua hnub, tseem hu ua hnub ci irradiance, nws txawv heev nyob ntawm koj qhov chaw nyob.
Cov cheeb tsam uas muaj hnub ci ntau dua (piv txwv li, Arizona, California, thaj chaw ntawm Australia) tuaj yeem tsim hluav taws xob ntau dua los ntawm lawv cov hnub ci vaj huam sib luag, uas txhais tau hais tias cov vaj huam sib luag tsawg dua yuav tsum tau ua kom tau raws li koj cov kev xav tau ntawm lub zog.
Cov cheeb tsam Cloudier lossis thaj chaw uas tsis muaj hnub ci ncaj qha (piv txwv li, Northern Europe lossis Pacific Northwest) yuav xav tau ntau lub vaj huam sib luag, vim tias lub hnub ci tawm ntawm ib lub vaj huam sib luag yuav qis dua.
Koj tuaj yeem txiav txim siab koj thaj chaw nruab nrab hnub nruab hnub nruab hnub siv cov cuab yeej xws li PVWatts Tshuab xam zauv lossis sab laj cov tuam txhab hnub ci zog hauv zos rau kev kwv yees raws li cov xwm txheej hauv zos.
4. Qhov System Losses
Nws yog ib qho tseem ceeb uas yuav tsum tau them nyiaj rau qhov kev poob qis uas tshwm sim thaum lub sij hawm hloov pauv ntawm tam sim no ncaj qha (DC) los ntawm cov vaj huam sib luag mus rau qhov hloov pauv tam sim no (AC) siv hauv koj lub tsev lossis kev lag luam. Qhov nruab nrab, hnub ci tshuab muaj txog li 10% poob vim qhov tsis muaj txiaj ntsig hauv inverter, thaiv, thiab lwm yam khoom. Qhov no txhais tau hais tias nyob rau hauv kev xyaum, tej zaum koj yuav xav tau me ntsis ntxiv panels tshaj qhov theoretical xam.
Xam tus naj npawb ntawm Panels rau 10 kW Hnub Ci System
Tam sim no peb nkag siab txog cov ntsiab lus tseem ceeb, cia peb suav pes tsawg lub vaj huam sib luag koj xav tau rau lub hnub ci 10 kW nyob rau hauv cov xwm txheej sib txawv.
1. Siv 300-Watt Panels
Rau 300-watt vaj huam sib luag thiab xav tias qhov kev pom zoo (qhov zoo tshaj plaws tshav ntuj thiab poob qis), koj yuav xav tau:
Tus lej ntawm Vaj Huam Sib Luag =10, 000 watts / 300 watts ib lub vaj huam sib luag =33.33 vaj huam sib luag
Yog li, 34 panels yuav tsum tau ua kom tiav 10 kW hnub ci system.
2. Siv 350-Watt Panels
Rau 350-watt panels, piv txwv li tej yam kev mob zoo:
Tus lej ntawm Vaj Huam Sib Luag =10, 000 watts / 350 watts ib lub vaj huam sib luag =28.57 vaj huam sib luag
Yog li, koj yuav xav tau nyob ib ncig ntawm 29 panels.
3. Kev sau nyiaj rau qhov kev poob
Yog tias peb suav txog 10% kev poob, tag nrho cov panels yuav tsum tau nce me ntsis:
Kho qhov System Loj =10, 000 watts × 1.10=11, 000 watts
Rau 300-watt panels:
11, 000 watts / 300 watts ib lub vaj huam sib luag =36.67 panels⇒37 vaj huam sib luag
Rau 350-watt panels:
11, 000 watts / 350 watts ib lub vaj huam sib luag =31.43 panels⇒32 panels
Lub luag haujlwm ntawmHnub ci Cablesthiab Solar Wires hauv 10 kW System
Thaum koj tau txiav txim siab ntau npaum li cas cov vaj huam sib luag koj xav tau rau koj qhov system 10 kW, nws yog ib qho tseem ceeb kom nkag siab txog lub luag haujlwm ntawm lub hnub ci cables thiab hnub ci xaim hauv kev ua kom lub cev ua haujlwm tau zoo.
1. Solar Cables
Cov kab hluav taws xob hnub ci tshwj xeeb yog tsim los txuas cov hnub ci vaj huam sib luag rau lub inverter thiab cov kab hluav taws xob lossis roj teeb cia. Cov kab hluav taws xob no yuav tsum ua kom ruaj khov, huab cua-resistant, thiab muaj peev xwm tuav tau qhov hluav taws xob siab thiab tam sim no uas lub hnub ci tsim.
TUV-rated cables: Cov no yog cov kab hluav taws xob zoo uas tau ntawv pov thawj rau kev siv lub hnub ci thiab tsim los tiv thaiv UV degradation, huab cua kub, thiab lwm yam ib puag ncig. Cov cables no feem ntau yog siv rau DC kev sib txuas ntawm cov hnub ci vaj huam sib luag thiab lub inverter.
MC4 hnub ci Cables: MC4 connector yog cov connector feem ntau rau hnub ci tshuab. Cov kab hluav taws xob no yog siv los txuas cov hnub ci vaj huam sib luag hauv kev sib txuas lossis kev teeb tsa sib txuas kom ua kom lub zog loj tshaj plaws.
2. Solar Wire Gauge
Qhov ntsuas ntawm cov hlau siv rau koj lub hnub ci kev teeb tsa yog lwm qhov tseem ceeb rau kev txiav txim siab. Qhov loj ntawm cov xaim cuam tshuam rau tus nqi tam sim no nws tuaj yeem nqa tau zoo thiab txo qis vim qhov tsis kam. Rau 10 kW hnub ci system, lub ntsuas hluav taws xob siv feem ntau yog li ntawm 10 AWG txog 6 AWG, nyob ntawm qhov kev ncua deb ntawm cov vaj huam sib luag thiab lub inverter, thiab qhov xav tau tam sim no.
10 AWG:Qhov ntsuas hluav taws xob no feem ntau siv rau kev ncua deb ntawm cov vaj huam sib luag thiab lub inverter, thiab nws feem ntau yog tsim rau cov tshuab uas muaj qhov hluav taws xob ntawm ib ncig ntawm 600V lossis qis dua.
6 AWG: Rau kev ncua ntev, los yog rau cov tshuab ua haujlwm ntawm cov hluav taws xob ntau dua, yuav tsum muaj cov hlau tuab xws li 6 AWG los tiv thaiv kev poob qis thiab txo qis zog.
3. Txuas rau Inverter
Inverters yuav tsum tau txuas nrog lub hnub ci array siv cov xaim tsim nyog. Qhov ntsuas ntawm cov hlau xav tau nyob ntawm qhov tam sim no lub inverter yog tsim los lis. 10 kW inverter yuav xav tau 8 AWG mus rau 6 AWG cables nyob ntawm tus inverter cov specifications.
