Yog tias koj xav txog hnub ci zog teeb rau koj lub tsev, ib lo lus nug tseem ceeb yog pes tsawg lub zog ci ntsa iab yuav tsum them lub roj teeb, xws li a15kWh lithium-ion qauvCov. Qhov no yog kev txhawj xeeb rau cov tswv tsev npaj khaws hnub ci zog rau hmo ntuj siv, kev tawm tsam, lossis txo cov phiaj xwm kev cia siab. Cov lus teb yog nyob ntawm cov txheej txheem zoo li vaj huam sib luag wattage, tshav ntuj teev, thiab kev ua haujlwm zoo. Cov ntawv no tsoo cov txheej txheem, muaj cov kev pom tseeb tiag, thiab sib piv cov kev paub txog kev pab koj kom txiav txim siab txog kev txiav txim hluav taws xob.
Nkag siab txog cov hauv paus
Ib qho 15kW li cas Lithium-ion roj teeb khw 15, ector} Cov khoom siv hauv tsev neeg yog ib nrab hnub, raws li cov khoom siv hluav taws xob hauv lub zog US Cov roj teeb lithium-ion, zoo li cov uas siv hauv tsev tshuab, muaj qhov siab tshaj plaws (}%) thiab ib qho tob) ntawm 90%, txhais tau hais txog 13.5KW yuav siv tau.
Hnub ci panels tsim hluav taws xob ntsuas hauv watts (w), thiab lawv cov zis niaj hnub yog nyob ntawm lawv cov weekically-feem 4 mus rau 6 teev nyob rau hauv feem ntau cov cheeb tsam. Txhawm rau them tus nqi 1KWH, koj xav tau cov panels txaus los tsim yam tsawg 15, 000 Wh, hloov kho rau qhov poob ntawm qhov tsis muaj peev xwm hauv lub roj teeb, inverter, thiab tus tswj hwm tus kheej.
Suav cov vaj huam sib luag hnub ci xav tau
Cia peb taug kev los ntawm kev ua lej uas siv cov kev xav tau tiag tiag. Lub vaj huam sib luag solar niaj hnub no ua 400-550 w. Rau qhov piv txwv, peb yuav siv lub vaj huam sib luag 450 thiab xav tias 5 teev ntawm lub hnub ci siab tshaj plaws hauv ib hnub, tus qauv kwv yees rau ntau qhov chaw nyob.
- Niaj Hnub Vaj Huam Sib Luag:
450W × 5 teev {2}}}}, 250th (2.25kWh) ib lub vaj huam sib luag.
- Panels xav tau:
Txhawm rau them tus nqi 15KWHWH, faib cov roj teeb uas muaj peev xwm los ntawm lub vaj huam sib luag cov khoom tsim tawm txhua hnub:
15, {{000 Wh ÷ 2,250Wh ≈ 6.67 panels.
Tshaj tawm, koj xav tau txog 7 panels.
- Accounting rau poob:
System tsis muaj peev xwm - xws li 5% poob, {5-10% inverter poob, thiab 5% kev tswj hwm poob-poob qis. Piv txwv tias muaj kev ua haujlwm tag nrho ntawm 85%, koj xav tau:
15, {{000} ÷ (2,25 {4}}} × 0.84 panels, lossis ntxug 8 panels.
Yog li, kwv yees li 8 panels rated ntawm 450W txhua, nrog 5 teev ntawm lub hnub ci, tuaj yeem them 15 zaug roj teeb rau ib hnub nyoog. Tus lej no sib txawv raws qhov chaw, huab cua, thiab vaj huam sib luag kev qhia.
Yam uas cuam tshuam rau cov vaj huam sib luag
Ob peb hloov pauv cuam tshuam kev suav:
- Hnub Ci Sijhawm: Cov cheeb tsam xws li Arizona Tau 6-7}} lub hnub ci ci ntsa iab, thaum lub sij hawm cloudier zoo li Seattle tej zaum yuav tau txais 3-4. Tsawg dua teev txhais tau tias ntau cov vaj huam sib luag.
- Vaj huam sib luag wattage: Cov Panels-wegas-weg (piv txwv li, 550W) txo tus lej uas xav tau. Piv txwv li, lub vaj huam sib luag ntawm 550W lub vaj huam sib luag tsim 2,750Wh txhua hnub (550W × 5 teev), xav tau hais txog {} panels rau ib qho 15kWh roj teeb.
- Kev txawj ntse: MPT cov tswj hwm kev tswj hwm (95% txuag) outperform pwm tswj (75-80%). Cov roj teeb lithium-ion poob tsawg dua li cov txhuas cov kua qaub ({%}% kev ua tau zoo).
- Tus nqi roj teeb: Lithium-ion roj teeb tuaj yeem ua rau them nyiaj sai (}}}. 5C tus nqi, tab sis overcharging kev pheej hmoo, yog li tus tswj hwm yog qhov tseem ceeb.
- Huab cua thiab Caij: Cov hnub huab lossis lub caij ntuj no txo cov zis tawm, muaj peev xwm xav tau cov panels lossis rov qab them rov qab los ntawm kab sib chaws.
Piv txwv li, ib tus tswv tsev nyob Florida yuav tsum muaj 7 panels, thaum ib tus hauv New York yuav xav tau 8 lossis 6 vim muaj hnub ci tsawg dua. Kev kuaj xyuas cov ntaub ntawv tsis txaus ntseeg tuaj yeem hloov kho cov kev kwv yees.
Tus Neeg Siv Lub Ntiaj Teb Tiag Tiag
Cov tswv tsev uas tau ua khub ob tog tog nrog cov hluav taws xob cia cov roj teeb muaj cov muaj txiaj ntsig:
- California, 12kWhwh: "Peb siv rau 500w panels kom them peb lub roj teeb, nws tau raug them ib nrab hnub, nws muaj tus neeg nyob hauv San Diego.
- Texas, 15kWhwh: "Yim 450W panels ua haujlwm rau peb, tab sis huab cua sov txhais tau tias peb qee zaum cia siab rau ntawm daim phiaj," sau tseg tus tswv tsev Austiner.
- Oregon, 10kWh: "Xya 400W Panels tsis txaus rau peb lub roj teeb thaum lub caij ntuj no, yog li peb ntxiv ib qho ntxiv," qhia tus neeg siv Portland.
Cov kev paub no tau hais txog qhov tseem ceeb ntawm vaj huam sib luag ntawm vaj huam sib luag cov naj npawb rau cov haujlwm hauv zos thiab kev hloov raws caij nyoog. Kev tshawb fawb txog 2024 los ntawm lub hnub ci kev lag luam koom nrog rau cov neeg siv hnub ci-cia-cia-cia lawv xav tau ntxiv rau cov hnub huab.
Kev sib piv kev sib piv: Roj teeb thiab cov vaj huam sib luag thiab cov vaj huam sib luag
Kev xaiv roj teeb thiab vaj huam sib luag teeb tsa kev cuam tshuam kev them nyiaj ua tau zoo. Ntawm no yog ib qho kev sib piv ntawm ob qho xwm txheej rau 15kWh lithium-ion roj teeb:

Cov kev txiav txim siab ntxiv
- Tswjhwm Ntsuam Xyuas: Tus mpt tswj hwm maximizes vaj huam sib luag tau tso zis tawm, tshwj xeeb tshaj yog nyob rau hauv lub hnub ci siab sib txawv. Rau ib qho 15kWh roj teeb, ib tus maub los ntsuas rau 3, 000-4}, {3}} w yog qhov raug.
- Inverter Sib Tw: Ua kom cov inverter kho lub roj teeb 48V tso zis (nquag rau 15kWh systems) thiab cov vaj huam sib luag 'lub zog sib xyaw.
- Kev muab cia: Panels yuav tsum fim sab qab teb (nyob rau sab qab teb hemisphere) ntawm 20-40}} degree tilt rau kev pom kev zoo.
- Kho: Tu thiab tshuaj xyuas kom tiv thaiv kev ua haujlwm ntawm cov plua plav los yog shading.
Cov ntsiab lus dav
Qhov xav tau cia cia khoom yog loj hlob raws li solar supple kev nce siab. Lub koom haum txuas ntxiv rau lub zog txuas ntxiv hluav taws xob ua haujlwm hauv ntiaj teb no lub zog yuav muaj 2030, tsav los ntawm cov kab ke nyob hauv nroog. Panels panels nrog lub roj teeb zoo li ib qho teeb meem 15kW li no koj ua kom cov txiaj ntsig hnub ci ua kom tiav, los ntawm cov nyiaj tau los ntawm kev tiv thaiv tawm. Txog cov ntsiab lus teb, ib qho roj teeb thib 5 yuav ua hluav taws xob yam tseem ceeb (fridge, wi-nkaus 5-7 txhua txhua hnub tseem ceeb ntawm kev thauj khoom.
Npaj koj teeb tsa
Los txiav txim koj lub vaj huam sib luag xav tau:
Txheeb xyuas cov hnub ua haujlwm hauv zos siv cov duab qhia hnub ci ntsa iab.
Kwv yees siv lub zog txhua hnub siv rau koj lub roj teeb thiab panels.
Sab laj tus kws tshaj lij los txhim kho vaj huam sib luag thiab system Cheebtsam.
Lub kaw lus muaj txiaj ntsig zoo raug nqi thiab ua tau zoo. Piv txwv li, oversizing nrog 9-10 panels tuaj yeem them nyiaj sai lossis npog 6-7 tej zaum yuav txaus hauv thaj chaw tshav ntuj.
Txuas rau Whet Zog
Zog Cia Khoom Roj Teebyog qhov tseem ceeb rau kov yeej hnub ci kev sib tw. Whet Zog lub zog 15KW fais fab hluav taws xob yog tsim rau kev sib koom ua ke nrog cov hnub ci, muab kev ua haujlwm siab thiab ruaj khov. Txuas mus xyuas peb tus xaib tshawb nrhiav seb nws yuav ua rau koj lub tsev ntseeg tau koj lub tsev.
