Ib qho qauv los txheeb xyuas koj lub sijhawm them rov qab
Lub sij hawm them rov qab txhais tau tias: pes tsawg xyoo kom txog thaum cov nyiaj koj txuag hluav taws xob ntxiv rau qhov koj siv rau hauv qhov system.
Lub sij hawm them rov qab (xyoo)=Tus nqi tag nrho ÷ Kev txuag nyiaj ib xyoos
Qhov ntawd yog nws.
Tag nrho tus nqi=khoom siv + kev teeb tsa + khoom siv (tshem tawm cov nyiaj pab lossis se credits)
Cov nyiaj txuag txhua xyoo=nyiaj txuag los ntawm lub sijhawm- ntawm- siv hloov pauv + nyiaj txuag los ntawm kev siv koj tus kheej lub hnub ci ntau dua + tus nqi ntawm kev muaj hluav taws xob thaub qab thaum muaj hluav taws xob
Thaum koj muaj cov lej no, cov lus teb yooj yim.
Kauj Ruam 1: Tus Nqi Them Nqi Them Hauv Tsev Cia Li Cas?
Hauv xyoo 2026, cov nqi cia hauv tsev tau poob ntau ntau piv rau ob peb xyoos dhau los. Cov nqi roj teeb thoob ntiaj teb tau poob txog 35% los ntawm lawv qhov siab tshaj plaws hauv 2022.
Nov yog cov nqi raug rau ntau qhov sib txawv:
| Qhov loj me | Hom kev siv | Tus nqi nruab (nrog rau kev teeb tsa) |
|---|---|---|
| 5 kWh | Qib nkag - tub yees, router, ob peb lub teeb | $5,000–$7,000 |
| 10 kWh | Standard tsev - txaus rau hmo ntuj | $9,000–$13,000 |
| 13.5 kWh | Nrov xaiv (xws li Tesla Powerwall chav kawm) | $12,000–$16,000 |
| 20 kWh | Lub tsev loj lossis tag nrho - tsev thaub qab | $16,000–$22,000 |
Coj ib10 kWh LFP systemua piv txwv. Nruab, koj nyob nraum saib roughly$9,000–$13,000.
Tus nqi tawg (siv $ 12,000 ua piv txwv):
Roj teeb hlwb (45–55% ntawm tag nrho): $4,500–$6,500
Hybrid inverter (15–20%): $1,500–$2,400
Kev teeb tsa ua haujlwm (15–25%): $1,500–$2,500
Qhov nyiaj tshuav ntawm qhov system (cables, keyboards, thiab lwm yam) (10-15%): $ 1,000- $ 1,800
Ib qho tseem ceeb:Tsis txhob cia li saib cov roj teeb uas pheej yig tshaj ua ntej. Lub roj teeb uas raug nqi $ 200 ntau dua ib kWh tab sis kav tsib xyoos ntev dua ua rau koj tus nqi qis dua ib kWh ntawm nws lub neej. Qhov koj xav saib yog qhovLevelized nqi cia (LCOS), tsis yog tus nqi ntawv nplaum xwb.
Kauj Ruam 2: Ntau npaum li cas cov nyiaj pab txhawb nqa koj txuag tau?
Ntau tus neeg tsis paub txog cov kev pab cuam no - lossis tsis paub yuav thov li cas.
Tebchaws Meskas:Tsoom fwv teb chaws Investment Tax Credit (ITC) muab rau koj30% rov qabraws li ib tug se credit. Nws nyob ntawm 30% txog 2032. Ntawm $12,000 system, uas yog $3,600 tawm. Koj tus nqi tawm ntawm - ntawm - hnab ris poob rau $ 8,400. Hauv California, kuj tseem muaj SGIP qhov kev pab cuam, uas ntxiv $ 150– $ 1,000 ib kWh hauv kev txhawb zog ntxiv.
Lub teb chaws Yelemees:Lub txhab nyiaj KfW muab nyiaj pab txog li 30%, capped ntawm € 6,600 ib lub tsev.
Australia:Qhov Small-Size Renewable Energy Scheme muab STC daim ntawv pov thawj muaj nqis txog $1,400–$2,000. Qee lub xeev ntxiv lawv qhov kev txhawb siab.
Tuam Tshoj:Txoj cai sib txawv raws lub nroog thiab lub xeev. Piv txwv li, hauv Yiyang, Hunan, cov tswv tsev tuaj yeem tau txais txog li 8,000 yuan (kwv yees $ 1,100) rau cov roj teeb cia yog tias lawv tseem muaj hnub ci ru tsev (tsawg kawg 5kW). Tianjin them $ 0.04 / kWh cov nyiaj pab them nqi (txog ntawm 5kWh ib hnub, siab tshaj $ 500 toj xyoo). 132 cov tsev neeg twb tau thov nws, qhov nruab nrab ntawm qhov ntxiv $ 40 toj ib hlis.
Xyuas seb muaj dab tsi muaj nyob hauv koj nyob.Ua li no tuaj yeem txiav koj lub sijhawm them rov qab los ntawm 1-2 xyoos.
Kauj Ruam 3: Koj tuaj yeem txuag tau ntau npaum li cas txhua xyoo?
Kev khaws cia txuag koj nyiaj hauv peb txoj hauv kev loj.
1. Lub Sijhawm - ntawm - siv arbitrage - qhov kev txuag ncaj qha tshaj plaws
Koj them lub roj teeb thaum hluav taws xob pheej yig (feem ntau thaum hmo ntuj) thiab siv thaum hluav taws xob kim (thaum nruab hnub nruab hnub). Qhov txawv ntawm cov nqi no yog koj txuag.
Saib ntawm 2026 cov ntaub ntawv,11 lub xeev hauv Suav teb muaj qhov siab tshaj / tawm - tus nqi sib txawv tshaj $ 0.14 ib kWh ** (1 yuan / kWh). **19 lub xeev muaj qhov sib txawv tshaj $0.08/kWh. Qhov siab tshaj plaws yog Shanghai ($ 0.24 / kWh), Hunan ($ 0.19 / kWh), thiab Zhejiang ($ 0.18 / kWh). Sichuan, Guangdong, Hainan, Hebei, Tianjin, Beijing, thiab Shandong kuj tseem siab dua $ 0.14.
Cia peb hais tias koj qhov siab tshaj / tawm - qhov sib txawv siab tshaj yog$0.11/kWh(0.8 yuan / kWh) - uas yog qhov tseeb rau ntau qhov chaw. Lub roj teeb 10kWh ua ib lub voj voog puv ib hnub:
Kev txuag txhua hnub=10kWh × $0.11=**$1.10/hnub**
Piv txwv li 300 hnub ntawm kev ua haujlwm hauv ib xyoos (sau nyiaj rau hnub huab cua lossis ib nrab ntawm cov voj voog):$1.10 × 300=$330/xyoo
Qhov loj dua qhov peak/off-peak gap, koj txuag ntau dua. Hauv Shanghai nrog qhov sib txawv ntawm $ 0.24, tib lub roj teeb 10kWh txuag txog $ 2.40 ib hnub - $ 720 toj xyoo.
2. Siab dua hnub ci tus kheej-siv - rau cov tsev uas muaj hnub ci vaj huam sib luag
Yog tias koj twb muaj lub hnub ci vaj huam sib luag, tsis muaj roj teeb koj muag koj lub hnub ci ntau dhau mus rau daim phiaj ntawm tus nqi qis (feem ntau yog $ 0.04- $ 0.10 / kWh). Tom qab ntawd thaum hmo ntuj, koj yuav lub zog rov qab los ntawm kab hluav taws xob ntawm tus nqi siab dua ($ 0.25- $ 0.45 / kWh). Qhov ntawd yog qhov phem.
Ntxiv ib lub roj teeb, thiab koj khaws koj lub sijhawm nruab hnub thiab siv thaum hmo ntuj. Qhov no tuaj yeem txiav koj lub sijhawm them rov qab los ntawm10-15 xyoo mus txog 5-7 xyoo. Qhov nce ib kWh yog qhov sib txawv ntawm tus nqi muag khoom thiab cov khoom noj -hauv tus nqi - feem ntau yog 4 txog 10 npaug.
3. Tus nqi thaub qab - koj txaus siab rau qhov no thaum lub hwj chim tawm
Qhov no yog ib qho nyuaj rau muab ib daim duab tseeb duas rau. Tab sis nyob rau hauv cov chaw uas tsis muaj kev ntseeg siab, poob lub zog rau ib teev tuaj yeem ua rau cov zaub mov tsis zoo hauv koj lub tub yees, tso tseg cov ntses ua liaj ua teb aeration, kaw lub lag luam hauv tsev, lossis so ib hnub ua haujlwm.
Yog tias koj ntsuas nws: hais tias koj muaj 4 qhov hluav taws xob hauv ib xyoos, txhua lub sijhawm 4 teev. Koj muaj nuj nqis txhua teev ntawm cov khoom lag luam poob hauv tsev ntawm $ 25. Qhov ntawd yog $400 ib xyoos hauv kev zam kev poob. Nws tsis tshwm sim hauv koj daim nqi hluav taws xob li "savings," tab sis nws yog nyiaj koj tsis poob. Hauv cov chaw uas muaj nqi hluav taws xob siab thiab cov phiajcim tsis zoo, tib neeg pom kev them rov qab rau hauv3-4 xyoos.
Muab tag nrho ua ke:Ib tug raug 10kWh system txuag roughly$800–$1,500 toj ib xyoonyob ntawm tus nqi hauv zos thiab kev siv hnub ci.
Kauj ruam 4: Cia peb xam lub sij hawm them rov qab
Pib nrog cov lej yooj yim tshaj plaws:
Tus nqi nruab nrab tom qab 30% ITC=$12,000 - $3,600 =$8,400
Txuag ib xyoos twg (conservative)=$800–$1,000
Them rov qab=$8,400 ÷ $900 ≈ 9.3 xyoo
Qhov ntawd yog qhov yooj yim tshaj plaws, kev kwv yees kwv yees.
Tam sim no siv tus lej tiag tiag:
Kev txuag txhua xyoo=siab dua hnub ci tus kheej-siv ($ 400) + sij hawm- ntawm- siv arbitrage ($ 350) + tus nqi thaub qab ($ 150)=**$900**
Them rov qab=$8,400 ÷ $900 ≈ 9.3 xyoo(Ib yam vim tias kev txuag ntau dua offsets qhov tsis muaj lwm yam - kho raws li koj qhov xwm txheej tiag tiag)
Yog tias koj nyob hauv thaj chaw siab - tus nqi nrog hnub ci zoo:
Txuag ib xyoos ib zaug=$800 (tus kheej-siv) + $500 (arbitrage) + $200 (paub)=**$1,500**
Them rov qab=$8,400 ÷ $1,500 ≈ 5.6 xyoo
LFP roj teeb feem ntau kav ntev dua 10 xyoo. Yog li tom qab koj tau them rov qab koj cov peev txheej, koj tseem muaj ntau xyoo ntawm kev txuag nyiaj dawb.
Kauj Ruam 5: Lub Sijhawm Them Rov Qab rau Cov Txheej Txheem Sib Txawv
