15kWh Solar Roj Teeb: PV Vaj huam sib luag sizing qhia

A 15KWH 51.2V Lithium Zog Cia Roj Teebyog ib qho ntau yam rau cov hnub ci, ua rau cov tsev ua haujlwm, cov lag luam me, lossis cov phiaj xwm tawm ntawm cov hlua khi thiab siv hluav taws xob txuas ntxiv. Kom zoo li lub photovoltaic (PV) panels yog qhov tseem ceeb los xyuas kom lub roj teeb them zoo thaum lub zog xav tau. Tsab ntawv no tshawb txog qhov tsawg thiab PV vaj huam sib luag ntau thiab tsawg PV vaj huam sib luag (nyob rau hauv kilowatts, kW) rau ib qho roj teeb, qhov cuam tshuam rau cov kev xaiv no, lawv cov kev cuam tshuam, thiab kev sib txawv ntawm kev siv. Kev kos duab ntawm kev paub txog kev ua haujlwm, cov qauv siv, thiab cov kev qhia lag luam, nws muaj cov lus qhia tseeb rau kev txhim kho hnub ci hluav taws xob cia.

PV vaj huam sib luag sizing rau ib tug 15kwha 51.2v roj teeb lithium

PV panels tsim ncaj qha tam sim no (DC) hluav taws xob los ntawm lub hnub ci, uas them cov roj teeb ntawm tus tswj hwm lossis hybrid inverter. Qhov loj ntawm PV array (hauv KW) txiav txim siab yuav ua li cas thiab ntseeg tau tias 15KWHED lub roj teeb tau raug them sai. Raws li cov vev xaib thiab kev ua lag luam, ntawm no yog ib qho kev qhia txog PV vaj huam sib luag yuav tsum muaj:

Yam tsawg kawg PV vaj huam sib luag loj

• Qho deb: 3-5 kw
• Kev ceeb toom: Qhov tsawg kawg nkaus PV loj nyob ntawm lub roj teeb muaj peev xwm, lub zog txhua hnub, thiab lub hnub ci hnub. Lub roj teeb 15KREWE yuav tsum muaj kwv yees li 15-16.5 kWh ntawm DC Zog kom tau them tag nrho, suav nyiaj txiag rau kev them nyiaj (90-9%) thiab cov txheej txheem los ntawm cov xaim thiab cov controllers). Hauv thaj chaw nrog 4-5 lub hnub ci taub hau (PSY.
• Tus yam ntxwv: Nyob rau hauv ib cheeb tsam nrog 4 ps, ib 3 kw pv array generates ~ txaus kom them ib tug 15k li cas, 70-80%) thaum muaj hwj chim me nra.

Siab Tshaj Pv Vaj Huam Sib Luag Loj

• Qho deb: 8-12 kw
• Kev ceeb toom: Qhov loj tshaj PV loj yog txwv los ntawm lub roj teeb them tam sim no, lub peev txheej muaj peev xwm, thiab tsim qauv. Ib tug 15kWh 51.2V roj teeb (3 {{{{}}}}}}}}}}}}}}), sib npaug rau 7.68-15.36 kw ntawm 51.2V. Lub sijhawm 8-12 kw ua kom nrawm nrawm nrawm nrawm hauv cov cheeb tsam siab (5-7) tsis muaj ntau lub zog muaj zog tuaj yeem thauj khoom lossis pub kab sib chaws. Oversizing tshaj 12 KW cov kev pheej hmoo hla lossis yuav tsum muaj cov tswj hwm siab tshaj plaws los txo cov nqi tam sim no, nce ntxiv.
• Tus yam ntxwv: Nyob rau hauv ib cheeb tsam nrog 5 psh, 10 kw arring generates ~ 50 kw

Qhov tseem ceeb cuam tshuam PV vaj huam sib luag sizing

Ntau yam kev txiav txim siab cov PV vaj huam sib luag tsim nyog rau ib qho 15kWh 51.2V lithium roj teeb, kev cuam tshuam, nqi, thiab kev ntseeg tau:

Lub hnub ci siab peak (psh):

• Kev piav txog: Cov sij hawm sib npaug ntawm lub hnub ci tag nrho (1000W \/ m²) qhov chaw tau txais txhua hnub, feem ntau 2.5-7 kWh \/ M² \/ M² nyob ntawm kev nyab xeeb. Piv txwv li, Tehran, Iran, Qhov ntsuas 2.5-7.4 kWh \/ M² \/ HNUB.
• Hloov: Tsawg zog psh yuav tsum muaj cov panels loj dua los tsim lub zog txaus kom them lub roj teeb. Hauv cov cheeb tsam qis (xws li, Seattle, 5-7 kw), thaum High-hnub thaj chaw (piv txwv li, Phoenix, 3-5 KW) xav tau me me arrays. Tsis txaus ntseeg ua rau qee qhov kev them ib nrab lossis kev cia siab rau ntawm cov haum fais fab.
• Tus Neeg Siv Tswv Yim: Tus neeg siv UK tau sau tseg, "Peb 4 KW Panels nyob rau hauv huab London (3 PSH) roj teeb tau maj mam them nyiaj rau peb lub roj Hmab Roj Av

Kev Siv Zog:

• Zaj piav: Tag nrho lub zog niaj hnub siv los ntawm tsev neeg lossis ua lag luam, ntsuas ntsuas hauv KWH. Piv txwv li, ib txoj kev siv UK Tsev Neeg ~ 3,400 kwh \/ xyoo, lossis ~ 9.3 kWh \/ hnub.
• Qhov tseem ceeb: PV panels yuav tsum tsim lub zog txaus kom them lub roj teeb thiab ua kom tau raws li kev noj ncaj qha. Rau ib qho 15kWh roj teeb nrog kev thauj khoom txhua hnub ntawm 10 kWh, PV array yuav tsum tau tsim ~ 25-27 kW hauv 4-5 thaj chaw psh.
• Tus Neeg Siv Tswv Yim: California tau qhia txog tus tswv tsev, "

Roj Teeb Them Zog:

• Zaj piav: Kev ua haujlwm ntawm lub zog hloov los ntawm PV lauj rau lub roj teeb, ib txwm 90-95% rau cov roj teeb lithium rau MPPT tswj.
• Qhov tseem ceeb: Poob los ntawm cov tswj hwm kev tswj hwm, xaim, thiab inverters yuav tsum tau ib qho loj dua PV array los them nyiaj. Rau ib qho 15kWh roj teeb, ~ 16-17 KWH ntawm PV kev tsim tawm yog xav tau.
• Hloov: Undersizing lub PV array tau ua rau qeeb qeeb charging, thaum oversizing ua kom nrawm nrawm nrawm dua tab sis nce nqi.

Lub kaw lus hom (kab sib chaws-khi, tawm-kab sib chaws, lossis hybrid):

• Zaj piav: Daim phiaj-khi cov tshuab xa tawm ntau lub zog, tawm-kab nruab nrab ntawm pv thiab roj teeb, thiab hybrid system ob qho tib si.
• Qhov tseem ceeb: Off-pob zeb tshuab yuav tsum tau loj PV arrays pv arrays pv arrays (6-8 kw) kom paub tseeb roj teeb Hybrid Systems sib npaug ob qho kev xav tau.
• Neeg Siv Kev Nyuaj Siab: Tus neeg siv cov khoom sib tw tawm hauv Australia hais tias, "Peb 8 kW panels xyuas kom peb 15kWh 51.2V roj teeb nyob qis, txawm tias nyob rau lub caij ntuj no nrog

Tus tswj hwm thiab Inverter Sib Tw:

• Zaj piav: Tus tswj hwm tswj hwm cov hluav taws xob hluav taws xob thiab tam sim no mus rau 51,2V roj teeb, thaum lub inverter hloov siab DC rau AC. Ob leeg yuav tsum tuav PVRay cov khoom tawm.
• Qhov tseem ceeb: 51.2v roj teeb xav tau cov kev tswj hwm nrog 40-60V tawm tswv yim thiab muaj peev xwm tam sim no (piv txwv li, 100-200 rau 5-10 kw). Oversized PV prorigns yuav suav cov kev txwv ntau tshaj, xav tau cov kev ntsuas sib txuas lossis qib siab MPP.
• Kev Taw Qhia: MPP tswj txhim kho txhim kho kev ua tau zoo los ntawm 15-20% piv rau PWM, txhawb kev txhawb nqa PV loj dua.

Environmentalency:

• Zaj piav: Cov xwm txheej zoo li shading, plua plav, vaj huam sib luag qaij, thiab qhov kub cuam tshuam rau cov zis pv. Kev kub siab rau cov muaj kev sib luag nrog kev sib tw ua ke los ntawm ~ {0. 5% ib degree dua 25 degree.
• Qhov tseem ceeb: Shading lossis suboptomal tilt yuav tsum tau 10-20% loj hlob los them nyiaj rau kev poob. Cov av muaj plua plav tuaj yeem txo cov zis los ntawm 5-10% yog tias tsis ntxuav kom huv tsis tu ncua.
• Tus Neeg Siv Tswv Yim: Ib South Africa Installer sau tseg, "Peb oversized peb 7 kW array rau ib tug 15kWh roj teeb kom suav nrog hmoov av thiab kub, txhim kho kev ntseeg tau."

Yav tom ntej nthuav dav:

• Zaj piav: Npaj yuav ntxiv roj teeb, ntim khoom, lossis daim phiaj chaw ua haujlwm yuav pov thawj ntau dua PVRay.
• Qhov tseem ceeb: Oversizing (piv txwv li, 8-10 kw) pub rau talabiles tab sis nce upfront nqi los ntawm $ 2, {, {, {5}}. Undersizing txwv yav tom ntej hloov khoom dua tshiab.
• Tus Neeg Siv Tswv Yim: Tus tswv ua lag luam hauv Tebchaws Yelemees tau hais tias, "Peb 10 kW panels rau ib 15KREP roj teeb muab rau peb chav roj tom qab."

Kev cuam tshuam thiab qhov sib txawv

PV vaj huam sib luag loj cuam tshuam rau kev ua haujlwm zoo, tus nqi, thiab cov neeg siv kev paub:

Qhov tsawg kawg nkaus (3-5 KW):
