Lub sam thiaj PV(Photovoltaics) tau txais kev nyiam heev hauv xyoo 2024-2025, ua rau muaj kev thov ntau heev hauv kev ua lag luam hauv Tebchaws Europe. Nws hloov "ob lub vaj huam sib luag + ib lub microinverter + ib txoj hlua fais fab" mus ua "lub chaw tsim hluav taws xob me me" uas yog plug-and-play, txawm tias rau cov neeg nyob hauv tsev ib txwm.
1. Kev Ntxhov Siab Txog Txoj Cai Lij Choj Txog Hluav Taws Xob ntawm Cov Neeg Nyob Hauv Tebchaws Europe
Tus nqi hluav taws xob nruab nrab hauv EU xyoo 2023 yog 0.28 €/kWh, nrog rau tus nqi siab tshaj plaws hauv lub teb chaws Yelemees nce siab tshaj 0.4 €/kWh. Cov neeg nyob hauv tsev, tsis muaj kev nkag mus rau ntawm lub ru tsev rau cov vaj huam sib luag hnub ci ib txwm muaj, tsuas yog tuaj yeem nyiaj tau cov nqi hluav taws xob siab txhua hli yam tsis muaj txoj hauv kev zoo los txuag nyiaj. Lub module balcony 400 Wp tuaj yeem tsim tau kwv yees li 460 kWh ib xyoos hauv Munich. Xam ntawm tus nqi hnyav ntawm 0.35 €/kWh, qhov no txuag tau kwv yees li 160 € txhua xyoo, tej zaum yuav them rau nws tus kheej hauv peb xyoos xwb - qhov kev thov zoo heev rau cov neeg nyob hauv tsev.
Xyoo 2023-2024, ntau tshaj 30 ntawm 56 lub chaw tsim hluav taws xob nuclear hauv Fabkis tau raug kaw vim yog kev xeb lossis kev rov ua kom rov qab muaj zog, ua rau lub zog hluav taws xob nuclear poob qis dua 25 GW qee zaum, qis dua qhov muaj peev xwm ntsuas ntawm 55 GW, uas ua rau tus nqi hluav taws xob hauv Tebchaws Europe nce siab. Txij lub Ib Hlis mus txog rau lub Ob Hlis 2024, qhov nruab nrab ntawm cua ceev hauv Hiav Txwv North yog li 15% qis dua li niaj zaus rau tib lub sijhawm, ua rau kwv yees li 20% xyoo-rau-xyoo hauv Nordic cua zog tso zis. Cov nqi siv rau lub zog cua hauv Denmark thiab Northern Germany poob qis dua 30%, nrog rau cov nqi lag luam hauv khw muag khoom pheej ntsib cov nqi tsis zoo ua ntej dhia siab dua 0.6 € / kWh. Daim ntawv qhia European Network of Transmission System Operators for Electricity (ENTSO-E) 2024 qhia tias lub hnub nyoog ua haujlwm nruab nrab ntawm 220 kV substations hauv cov tebchaws xws li Lub Tebchaws Yelemees thiab Fabkis tshaj 35 xyoo. Qhov tsis muaj cov khoom siv hluav taws xob ntau ua rau muaj kev cuam tshuam ntau zaus ntawm kev xa hluav taws xob hauv zos, ua rau kev hloov pauv ntawm tus nqi hluav taws xob txhua hnub nthuav dav mus txog 2.3 npaug ntawm xyoo 2020. Qhov no ua rau cov nqi hluav taws xob rau cov neeg nyob hauv European zoo li caij tsheb ciav hlau.
2. Cov Nqi Poob Ntawm Cov Khoom Siv Hluav Taws Xob Tshiab Ua Rau PV thiab Chaw Cia Khoom Mus Rau Hauv Tsev Neeg
Tau peb xyoos dhau los no, tus nqi ntawm cov PV modules, microinverters, thiab cov roj teeb cia khoom tau txo qis tag nrho ntau dua 40%. Tus nqi ntawm cov modules me me hauv qab 800 Wp tau mus txog qib khoom lag luam. Lub caij no, cov kev daws teeb meem txuas-thiab-ua si tau ua rau cov txheej txheem teeb tsa yooj yim dua, txo cov nqi xa tawm thiab txhawb nqa sai sai rau kev siv balcony PV thiab cov tshuab cia hluav taws xob loj.
3. Txoj Cai & Kev Tswjfwm: Txij Li Kev Pom Zoo Tsis Pom Zoo Mus Rau Kev Txhawb Nqa
- Txoj Cai Lij Choj Txog Kev Siv Hluav Taws Xob Rov Ua Dua Tshiab ntawm Lub Tebchaws Yelemees (EEG 2023) tau faib ua pawg "≤800 Wp balcony PV" uaStecker-Solar, zam nws los ntawm kev pom zoo, kev ntsuas, thiab cov nqi them rau lub network, tab sis tseem txwv tsis pub muab hluav taws xob rov qab rau hauv lub network pej xeem los ntawm cov qhov hluav taws xob ntiag tug.
- Xyoo 2024 "Kev Tswj Xyuas PV Faib Tawm (Draft for Comment)" ntawm Tuam Tshoj teev cov "balcony PV" ua "qhov xwm txheej me me" tab sis hais meej meej tias cov qauv "kev siv tus kheej tag nrho" yuav tsum tau nruab nrog cov khoom siv tiv thaiv hluav taws xob rov qab; txwv tsis pub, nws yuav raug kho raws li kev ua txhaum cai siv hluav taws xob.
- Fabkis, Ltalis, thiab Spain tau tsim cov platform rau kev sau npe "plug-in PV" uas cov neeg siv yuav tsum cog lus ua ntej rau "zero reverse power flow" kom tsim nyog rau kev pab nyiaj rau kev siv tus kheej ntawm 0.10–0.15 € / kWh.
Kev txhawb nqa txoj cai tau dhau los ua lub hauv paus rau kev siv lub sam thiaj PV, tab sis yuav tsum tau them sai sai rau kev ua raws li cov cai tiv thaiv kev ntws hluav taws xob rov qab. Qhov no yog qhov uas cov ntsuas ntse ua qhov tseem ceeb.
4. Vim li cas lub Balcony PV System thiaj xav tau OWON WiFi Smart Meter?
OWON, ib lub tuam txhab tsim khoom siv IoT uas muaj ntau tshaj 20 xyoo ntawm kev paub dhau los, tsom mus rau kev tswj hwm lub zog thiab kev daws teeb meem ntse hauv tsev. NwsPC341 WiFi Ntsuas Ntseyog tsim los rau cov xwm txheej zoo li lub sam thiaj PV thiab muaj cov yam ntxwv hauv qab no:
- Qhov Xwm Txheej Sib Txuas Lus Sib Xws:Cov tsev nyob feem ntau tsis muaj cov xwm txheej rau RS-485 xov hlau, thiab 4G/NB-IoT raug nqi txhua xyoo. WiFi, nrog ze li ntawm 100% kev pabcuam, yog ib txoj hauv kev sib txuas lus zoo heev rau cov ntsuas ntse hauv cov xwm txheej PV ntawm lub sam thiaj. PC341 txhawb nqa 802.11 b/g/n @ 2.4GHz WiFi kev sib txuas.
- Qhov Tseem Ceeb ntawm Kev Tiv Thaiv Fais Fab Rov Qab:Lub ntsuas yuav tsum tau ntes tau qhov tshwm sim ntawm kev ntws hluav taws xob rov qab sai sai. Lub PC341 txhawb nqa kev ntsuas hluav taws xob ob txoj kev, saib xyuas ob qho tib si hluav taws xob siv thiab tsim tawm (suav nrog hluav taws xob ntau dhau uas pub rov qab rau lub grid). Nws lub voj voog tshaj tawm txhua 15 vib nas this pab lub kaw lus teb raws sijhawm.
- Yooj yim rau kev teeb tsa:Feem ntau, cov PV hauv Balcony yog ib qho project uas kho dua tshiab, uas yuav tsum tau ntxiv lub 'meter' rau ntawm qhov chaw txuas PV grid, feem ntau yog nyob hauv lub rooj tsav xwm faib khoom hauv tsev uas twb muaj lawm. Lub PC341 txhawb nqa kev teeb tsa ntawm phab ntsa lossis DIN rail. Nws cov CTs tseem ceeb thiab cov CTs me me siv cov txuas suab peb-pole (3.5mm thiab 2.5mm feem) nrog cov cables 1-meter, thiab cov transformers tam sim no sib cais ua rau kev teeb tsa sai, haum zoo rau hauv cov rooj tsav xwm faib khoom hauv tsev me me.
- Kev Ntsuas Ob Txoj Kev Yog:Tej zaum yuav tsum tau hloov cov 'meter' qub uas tsis txhawb nqa kev ntsuas ob txoj kev. Lub PC341 tau tsim tshwj xeeb rau kev ntsuas lub zog ob txoj kev, saib xyuas kev siv thiab kev tsim khoom kom raug, ua tau raws li qhov xav tau ntawm cov xwm txheej PV ntawm lub sam thiaj. Nws qhov kev ntsuas qhov tseeb yog nyob hauv ± 2% rau cov khoom thauj ntau dua 100W.
- Tus Nqi Tshaj Tawm Cov Ntaub Ntawv:Lub PC341 muab kev ntsuas lub sijhawm tiag tiag ntawm voltage, tam sim no, lub zog fais fab, lub zog nquag, thiab zaus, nrog rau kev tshaj tawm cov ntaub ntawv tsis tu ncua, pab saib xyuas kev hloov pauv fais fab.
- Kev Muaj Peev Xwm Sib Txuas Lus:Kev sib txuas lus WiFi ntawm PC341 tsis tas yuav siv cov xov hlau sib txuas lus ntxiv; tsuas yog txuas rau lub network wireless hauv tsev uas twb muaj lawm ua rau muaj kev xa cov ntaub ntawv, txo qhov nyuaj ntawm kev teeb tsa thiab cov nqi tsim kho. Qhov no kuj tseem ua rau kev nthuav dav ntawm lub kaw lus yav tom ntej yooj yim dua. Feem ntau cov microinverters siv rau hauv cov kab ke PV balcony kuj txhawb nqa kev sib txuas lus WiFi, uas tso cai rau ob qho tib si lub 'meter' thiab microinverter txuas rau lub network WiFi hauv tsev.
- Kev Sib Txuas Lus thiab Kev Ywj Pheej ntawm Lub System:Lub PC341 siv tau nrog cov tshuab ib theem, ob theem (120/240VAC), thiab peb theem plaub-xaim (480Y/277VAC), uas hloov kho rau ntau yam hluav taws xob. Nws tuaj yeem saib xyuas lub zog tag nrho hauv tsev thiab txog li 16 lub voj voog (siv 50A sub CTs), muab kev ywj pheej rau kev nthuav dav ntawm lub kaw lus.
- Kev Ntseeg Siab thiab Daim Ntawv Pov Thawj:Lub PC341 nqa daim ntawv pov thawj CE thiab ua haujlwm tau zoo hauv qhov kub thiab txias dav (-20 ℃ ~ + 55 ℃), tsim nyog rau cov chaw teeb tsa sab hauv tsev.
5. Xaus Lus: OWON WiFi Smart Meter - Ib qho tseem ceeb rau Balcony PV Systems
Cov tshuab PV ntawm lub sam thiaj hloov ntau lab lub sam thiaj nyob hauv tsev mus ua "cov chaw tsim hluav taws xob me me." Lub ntsuas WiFi ntse zoo li OWON PC341 pab cov tshuab no ua haujlwm hauv "kev ua raws li, ntse, muaj kev nyab xeeb, thiab ua haujlwm tau zoo". Nws ua ntau lub luag haujlwm tseem ceeb suav nrog "kev ntsuas, kev saib xyuas, thiab kev sib txuas lus." Saib mus tom ntej, nrog rau kev siv ntxiv ntawm kev ntsuas tus nqi dynamic, kev lag luam carbon, thiab V2G, lub ntsuas ntse lub luag haujlwm yuav hloov pauv ntau dua li kev ntws hluav taws xob tiv thaiv rov qab, tej zaum yuav hloov kho kom dhau los ua lub hauv paus tseem ceeb hauv lub tshuab tswj hluav taws xob hauv tsev, ua rau txhua kilowatt-teev ntawm hluav taws xob ntsuab pom tau, tswj tau, thiab ua kom zoo tshaj plaws, qhia txog "mais kawg" ntawm kev nyob tsis muaj carbon.
OWON Technology muab cov kev daws teeb meem dav dav xws li cov khoom lag luam IoT txheem mus rau cov kev pabcuam ODM. Nws cov kab khoom thiab kev txawj ntse tuaj yeem txhawb nqa lub sam thiaj PV systems thiab cov ntawv thov kev tswj hwm lub zog hauv tsev dav dua.
