Ib tus neeg nyob ze ntawm kuv tau teeb tsa $ 22,000 tawm -daim phiaj hnub ci ntawm lub tsev nyob hauv nroog uas yog 50 ko taw los ntawm tus ncej hluav taws xob. Nws xav tau "ua tiav lub zog ywj pheej." Qhov nws tau txais yog lub tshuab hluav taws xob ua haujlwm peb teev txhua lub caij ntuj no thaum yav tsaus ntuj vim nws undersized nws lub txhab nyiaj roj teeb, thiab daim nqi hluav taws xob ntawm $ 0 hloov los ntawm daim nqi diesel ntawm $ 180 / hli. Nws yuav txuag tau $ 15,000 ua ntej thiab $ 2,000 / xyoo hauv roj los ntawm kev mus rau daim phiaj{13}} khi nrog lub roj teeb thaub qab.
Kev xaiv ntawm -grid, off-grid, thiab hybrid tsis yog hais txog qhov system "zoo tshaj." Nws yog hais txog qhov system twg phim koj qhov chaw, koj cov peev nyiaj, koj cov nqi siv hluav taws xob, thiab ntau npaum li cas tsis yooj yim koj kam kam rau thaum lub hnub tsis ci.
Ntawm -Grid (Grid-Tied): Qhov yooj yim thiab pheej yig tshaj xaiv
Ib qho ntawm -daim phiaj hnub ci txuas ncaj qha mus rau daim phiaj siv hluav taws xob. Hnub ci vaj huam sib luag pub ib daim phiaj- khi inverter, uas hloov DC rau AC thiab synchronizes nrog daim phiaj. Thaum koj cov vaj huam sib luag tsim ntau dua li koj lub tsev siv, ntau lub zog ntws mus rau hauv daim phiaj. Thaum koj xav tau ntau tshaj li koj cov panels tsim, koj kos los ntawm daim phiaj.
Tsis muaj roj teeb. Tsis muaj nqi controllers. Tsis muaj thaub qab thaum muaj teeb meem.
Qhov kawg taw tes ua rau tib neeg xav tsis thoob. Thaum daim phiaj nqes mus, tus qauv kab sib chaws - khi system kaw - raws li txoj cai. Nws yog hu ua anti-Islanding tiv thaiv, yuav tsum tau los ntawm NEC 705 thiab IEEE 1547. Yog tias koj lub inverter khaws cia lub zog noj rau hauv cov kab downed, nws tuaj yeem electrocute ib lineman ua hauj lwm los kho cov kev pab cuam.
Kev Lag Luam
Ntawm - kab hluav taws xob yog tus nqi tshaj plaws - kev teeb tsa hnub ci zoo vim tias koj tab tom yuav cov khoom tsawg tshaj plaws:
| Cheebtsam | Tus nqi raug (6 kW thaj chaw) |
|---|---|
| Hnub ci vaj huam sib luag (6kW) | $5,400–$7,200 |
| Daim phiaj- khi hlua inverter | $1,000–$2,000 |
| Mounting, thaiv, tso cai | $2,000–$4,000 |
| Tag nrho ua ntej kev txhawb siab | $8,400–$13,200 |
| Tom qab 30% ITC | $5,880–$9,240 |
Nrog net metering (muaj nyob rau hauv Teb Chaws Asmeskas feem ntau), koj cov nqi hluav taws xob tso cai rau koj rau ntau lub zog xa tawm mus rau daim phiaj - feem ntau ntawm lossis ze tus nqi muag khoom. Ib qhov dej -size grid- khi system nyob rau hauv ib lub xeev nrog tag nrho net metering yuav txo tau koj cov nqi hluav taws xob los ntawm 70-100%, nrog them rov qab nyob rau hauv 5-8 xyoo.
⚡ Kev Tshawb Fawb:Net metering txoj cai hloov pauv. California's NEM 3.0 tau txiav cov qhab nia xa tawm los ntawm kwv yees li 75%. Hawaii yeej tseem ceeb tshem tawm net metering xyoo dhau los. Yog tias koj lub xeev txo cov nyiaj them poob haujlwm, daim phiaj dawb huv - khi txoj kab yuav tsis txaus nyiam - thiab ntxiv roj teeb (hybrid) pib ua rau kev txiav txim siab nyiaj txiag.
Qhov zoo tshaj plaws rau:Cov tsev uas muaj kev nkag tau rau daim phiaj kev ntseeg tau thiab cov kev cai metering zoo. Cov peev nyiaj -cov neeg yuav khoom uas xav tau lub sijhawm them rov qab sai tshaj plaws.
Tawm- Daim phiaj: Tag Nrho Kev ywj pheej ntawm tus nqi
Ib qho tawm -daim phiaj hnub ci muaj xoom txuas rau daim phiaj siv hluav taws xob. Txhua yam koj siv hauv tsev yuav tsum yog tsim los ntawm koj lub vaj huam sib luag thiab khaws cia rau hauv koj lub roj teeb. Tsis muaj kab sib chaws kom poob rov qab thaum lub hnub tsis ci.
Qhov no yuav tsum muaj ntau yam khoom siv:
- Hnub ci vaj huam sib luag (feem ntau yog loj los ntawm 30–50% vs. ntawm -grid)
- Charge controller (MPPT hom rau kev ua haujlwm siab tshaj plaws)
- Lub txhab nyiaj roj teeb (LiFePO4, qhov loj me rau 2-3 hnub ntawm kev tswj hwm tus kheej)
- Tawm - daim phiaj lossis hybrid inverter (nrog daim phiaj- muaj peev xwm tsim tau)
- Backup generator (rau ncua sijhawm huab cua thiab lub caij ntuj no tsis txaus)
Kev Lag Luam
| Cheebtsam | Tus nqi raug (6 kW + 20 kWh cia) |
|---|---|
| Hnub ci vaj huam sib luag (8 kW, loj) | $7,200–$9,600 |
| MPPT tus nqi tswj | $500–$1,200 |
| Roj teeb lub txhab nyiaj (20 kWh LiFePO4) | $8,000–$14,000 |
| Tawm -grid inverter | $2,000–$4,000 |
| Backup generator | $1,000–$3,000 |
| Mounting, thaiv, sib npaug ntawm qhov system | $3,000–$6,000 |
| Tag nrho ua ntej kev txhawb siab | $21,700–$37,800 |
Qhov ntawd yog 2–3 × tus nqi ntawm qhov sib npaug ntawm - kab sib chaws. Thiab tsis zoo li kab hluav taws xob- khi cov tshuab uas them lawv tus kheej rov qab los ntawm kev txuag hluav taws xob, tawm - cov kab hluav taws xob hloov cov nqi hluav taws xob nrog kev saib xyuas thiab cov peev nyiaj siv roj (lub tshuab hluav taws xob, kev hloov roj teeb thaum kawg).
Pro Tip - Loj rau Lub Ib Hlis, tsis yog Lub Xya Hli.Qhov feem ntau tawm ntawm - kab sib chaws yuam kev yog sizing lub kaw lus raws li lub caij ntuj sov hnub ci. Nyob rau sab qaum teb Asmeskas, Lub Kaum Ob Hlis / Lub Ib Hlis Hnub Ci tuaj yeem yog 25-35% ntawm Lub Xya Hli tso tawm. Yog tias koj lub txhab nyiaj roj teeb tsuas yog nqa ib hnub ntawm kev tswj hwm tus kheej thiab koj ntaus ib lub lim tiam ntawm huab cua lub caij ntuj no, koj tab tom khiav koj lub tshuab hluav taws xob txhua hnub. Tsim rau koj lub hli hnub ci phem tshaj plaws, ntxiv 2-3 hnub ntawm lub roj teeb autonomy, thiab pob nyiaj siv rau lub tshuab hluav taws xob. Rau cov ncauj lus kom ntxaws roj teeb qhov loj me, saib peb phau ntawv qhianyob hauv lub zog cia systems.
Qhov zoo tshaj plaws rau:Tej thaj chaw deb uas tsis muaj kab sib chaws nkag tau (lossis qhov twg cov nqi sib txuas sib txuas ntau dua $ 20,000- $ 50,000). Cabins, ranches, thiab off-daim phiaj vaj tsev nyob qhov twg lub zog muaj kev ywj pheej yog qhov tseem ceeb ntawm kev ua neej, tsis yog kev suav nyiaj txiag xwb.
Hybrid: Qhov zoo tshaj plaws ntawm ob lub ntiaj teb (ntawm tus nqi)
Ib lub hnub ci hybrid txuas rau daim phiaj thiab suav nrog cov roj teeb cia. Lub hybrid inverter tswj kev sib cuam tshuam ntawm lub hnub ci vaj huam sib luag, roj teeb, thiab daim phiaj - txiav txim siab hauv lub sijhawm tiag tiag seb puas yuav siv hnub ci ncaj qha, them lub roj teeb, kos los ntawm daim phiaj, lossis xa mus rau daim phiaj.
Qhov no yog qhov nrawm tshaj plaws - ntu loj hlob ntawm thaj chaw hnub ci kev lag luam, thiab yog vim li cas: nws daws ob qhov kev txwv loj tshaj plaws ntawm lwm cov vaj tsev.
Teeb meem kab - khi tsis tuaj yeem daws tau:Fais fab tuag. Lub hybrid system nrog roj teeb thaub qab ua rau koj cov khoom tseem ceeb khiav thaum daim phiaj poob qis.
Teeb meem tawm - kab sib chaws daws tsis tau:Lub caij ntuj no shortfalls thiab oversizing nqi. Lub tshuab hybrid kos los ntawm kab sib chaws thaum lub hnub ci thiab roj teeb ua haujlwm luv luv - tsis muaj lub tshuab hluav taws xob xav tau, tsis tas yuav muaj qhov loj me.
