Kutheni iBalcony PV System ifuna iOWON WiFi Smart Meter?

Ibhalkhoni yePV(Photovoltaics) ngequbuliso yafumana ukuthandwa okukhulu ngo-2024-2025, ifumana imfuno yentengiso eqhumayo eYurophu. Iguqula "iipaneli ezimbini + i-microinverter enye + intambo yamandla enye" ​​ibe "yiplanti yamandla encinci" eyiplagi kunye nokudlala, kunye nabahlali abaqhelekileyo abahlala kwiiflethi.

1. Ukuxhalaba kweBill yaMandla abahlali baseYurophu

Umyinge wexabiso lombane wasekhaya we-EU ngo-2023 wawuyi-0.28 €/kWh, kunye namazinga aphezulu eJamani anyuke ngaphezu kwe-0.4 €/kWh. Abahlali bezindlu, abangenaluphahla lwezindlu zeepaneli zelanga eziqhelekileyo, banokunyamezela kuphela amatyala aphezulu ombane wenyanga ngaphandle kwendlela esebenzayo yokonga imali. Imodyuli ye-balcony ye-400 Wp inokuvelisa malunga ne-460 kWh ngonyaka eMunich. Ibalwe ngexabiso elilinganisiweyo le-0.35 €/kWh, oku konga malunga ne-160 € ngonyaka, enokuthi ihlawule ngokwayo kwiminyaka emithathu nje - isiphakamiso esinomtsalane kakhulu kubahlali bezindlu.

Ngo-2023-2024, ngaphezu kwama-30 kwii-reactors zenyukliya zaseFransi ezingama-56 zavalwa ngenxa yoxinzelelo lwe-corrosion okanye i-refueling, ebangela ukuba amandla enyukliya aphume ngaphantsi kwe-25 GW ngamanye amaxesha, ngaphantsi komthamo olinganisiweyo we-55 GW, uqhuba ngokuthe ngqo amaxabiso ombane eYurophu. Ukusukela ngoJanuwari ukuya kuFebruwari 2024, umndilili wesantya somoya kuLwandle lwaseMantla ubumalunga ne-15% ngaphantsi kunesiqhelo kwangelo xesha, nto leyo ekhokelele kukwehla okuqikelelwa kuma-20% unyaka nonyaka kwimveliso yamandla omoya eNordic. Amazinga okusetyenziswa kwamandla omoya e-Denmark nakwi-Northern Germany yehle ngaphantsi kwe-30%, kunye namaxabiso emarike ahlala efumana amaxabiso amabi ngokuphindaphindiweyo phambi kokuba atsibe ngaphezulu kwe-0.6 €/kWh. Ingxelo ye-European Network of Transmission System Operators for Electricity (ENTSO-E) 2024 ingxelo ibonise ukuba umndilili weminyaka yokusebenza ye-220 kV substations kumazwe afana neJamani neFransi idlula iminyaka engama-35. Ukuncipha kokufumaneka kwezixhobo kukhokelela kwiibhotile zokudluliselwa kwendawo rhoqo, okubangela ukuguquguquka kwexabiso le-intraday ukwandisa ukuya kumaxesha angama-2.3 ka-2020. Oku kwenza ukuba amatyala ombane kubahlali baseYurophu abahlali bafane ne-roller coaster ride.

2. Iindleko ezihlayo zesiXhobo saMandla esitsha Qhuba iPV kunye noGcino kuMakhaya

Kule minyaka mithathu idlulileyo, iindleko zeemodyuli ze-PV, i-microinverters, kunye neebhetri zokugcina ziye zehla nge-40%. Ixabiso leemodyuli ezincinci ezipakishwe ngaphantsi kwe-800 Wp ziye zafikelela kumanqanaba empahla. Okwangoku, izisombululo zoxhulumaniso lwe-plug-and-play ziye zalula kakhulu inkqubo yokufakela, ngokuphawulekayo ukunciphisa iindleko zokuthunyelwa kwenkqubo kunye nokukhuthaza ngokukhawuleza ukusetyenziswa kwe-balcony PV kunye neenkqubo zokugcina amandla.

3. Umgaqo-nkqubo kunye noMgaqo: Ukusuka kulwamkelo olufihlakeleyo ukuya kwiNkuthazo

• Umthetho waMandla aVuselelekayo waseJamani (EEG 2023) uhlela ngokusemthethweni “≤800 Wp balcony PV” njengeI-Stecker-Solar, ikhululwe ekuvunyweni, ukulinganisa, kunye neentlawulo zegridi, kodwa isakwalela ukondla umbane kwakhona kwigridi kawonke-wonke ngokusebenzisa iisokethi zabucala.
• I-China's 2024 "Imilinganiselo yoLawulo lwe-PV eSasazwe (i-Draft for Comment)" idwelisa "i-balcony PV" njenge "scenario encinci" kodwa ichaza ngokucacileyo ukuba iimodeli "zokuzisebenzisa ngokupheleleyo" kufuneka zixhotyiswe ngezixhobo zokukhusela ukuhamba kwamandla okubuyela umva; ngaphandle koko, kuya kuthathwa njengokuphulwa kwemigaqo yokusetyenziswa kombane.
• IFransi, i-Italiya, kunye ne-Spain ngaxeshanye baqalise iiplatifomu zokubhalisa ze-"plug-in PV" apho abasebenzisi kufuneka baqale bazibophelele "ekuhambeni kombane okubuyisela umva" ukuze bafanelekele ukufumana inkxaso-mali yokuzisebenzisa ye-0.10–0.15 €/kWh.

Inkxaso yomgaqo-nkqubo ibe yintsika yokuphunyezwa kwe-balcony ye-PV, kodwa ingqwalasela kufuneka ihlawulwe ukuthotyelwa kwemimiselo yokulwa nokujikeleza kwamandla. Apha kulapho iimitha ezihlakaniphile zibaluleka khona.

4. Kutheni iBalcony PV System ifuna iOWON WiFi Smart Meter?

I-OWON, isixhobo se-IoT uMvelisi woYilo oluQhelekileyo oneminyaka engaphezu kwama-20 yamava, ugxile kulawulo lwamandla kunye nezisombululo zokwakha ezikrelekrele. YaloPC341 WiFi Smart Meteryenzelwe iimeko ezifana ne-balcony PV kwaye inikezela ngezi zinto zilandelayo:

• Imeko yoNxibelelwano oluhambelanayo:Izakhiwo ze-Apartment zihlala zingenayo imiqathango ye-RS-485 i-wiring, kunye ne-4G / NB-IoT ingenisa imali yonyaka. I-WiFi, ephantse ibe yi-100% yokugubungela, yindlela yonxibelelwano efanelekileyo kakhulu kwiimitha ezihlakaniphile kwi-balcony ye-PV scenarios. I-PC341 ixhasa i-802.11 b/g/n @ 2.4GHz uqhagamshelwano lwe-WiFi.
• Amandla okuHamba okuBalulekileyo okuchasene nokuBuyisa:Isilinganisi-manzi sidinga ukubona ukwenzeka kokuhamba kombane umva ngokukhawuleza. I-PC341 ixhasa umlinganiso we-bi-directional energy, ukubeka iliso kokubini okusetyenzisiweyo kunye nokuveliswa kwamandla (kubandakanya amandla angaphezulu abuyiselwe kwigridi). Umjikelo wayo wokunika ingxelo rhoqo ngemizuzwana ye-15 unceda inkqubo ukuba iphendule ngexesha.
• Ukuhlohla-Kulungele:I-Balcony PV ngokuqhelekileyo yiprojekthi yokubuyisela kwakhona, efuna imitha yongezwa kwindawo yokudibanisa igridi ye-PV, ngokuqhelekileyo ngaphakathi kwebhodi ekhoyo yokuhanjiswa kwendlu. I-PC341 ixhasa udonga okanye ukufakwa kukaloliwe weDIN. Ii-CTs zayo eziphambili kunye ne-sub CTs zisebenzisa izixhumi zomsindo we-pole ezintathu (3.5mm kunye ne-2.5mm ngokulandelanayo) kunye neentambo zeemitha ezi-1, kunye ne-split-core current transformers ziququzelela ukufakwa ngokukhawuleza, ukufakwa kakuhle ngaphakathi kweebhodi zokusasaza ekhaya.
• Ulinganiso oluchanekileyo lwe-Bi-directional:Iimfuno zolawulo zisenokufuna ukutshintshwa kweemitha ezindala ezingaluxhasiyo umlinganiselo we-bi-directional. I-PC341 yenzelwe ngokukodwa ukulinganisa amandla amabini, ukubeka iliso ngokuchanekileyo kokubini ukusetyenziswa kunye nemveliso, ukuhlangabezana neemfuno zobugcisa beemeko ze-balcony PV. Ukuchaneka kwayo kokulinganisa ukulinganisa kungaphakathi kwe ±2% kwimithwalo> 100W.
• Ixabiso leNgxelo yeDatha:I-PC341 ibonelela ngemilinganiselo yexesha lokwenyani lombane, okwangoku, amandla ombane, amandla asebenzayo, kunye nokuphindaphindwa, kunye nengxelo yedatha eqhelekileyo, inceda ekubekeni iliso kutshintsho lwamandla.
• Ubunakho boNxibelelwano:Unxibelelwano lwe-WiFi lwe-PC341 luphelisa imfuno yonxibelelwano olongezelelweyo; ukudibanisa nje kuthungelwano olukhoyo lwekhaya olungenazingcingo lwenza ukuba udluliselo lwedatha, lunciphise kakhulu ubunzima bofakelo kunye neendleko zokwakha. Oku kukwaququzelela ukwandiswa kwenkqubo yexesha elizayo. Uninzi lwee-microinverters ezisetyenziswa kwi-balcony ye-PV iinkqubo zikwaxhasa unxibelelwano lwe-WiFi, ezivumela zombini imitha kunye ne-microinverter ukuba ziqhagamshelane nenethiwekhi ye-WiFi yasekhaya.
• Ukuhambelana neSistim kunye noBubhetyebhetye:I-PC341 iyahambelana ne-single-phase, i-split-phase (120/240VAC), kunye ne-three-phase-four-wire (480Y/277VAC) iinkqubo, ukuziqhelanisa neendawo ezahlukeneyo zombane. Iyakwazi ukubeka iliso kumandla wekhaya lonke kunye nokuya kuthi ga kwi-16 iisekethe zomntu ngamnye (usebenzisa i-50A sub CTs), enikezela ukuguquguquka kokwandiswa kwenkqubo.
• Ukuthembeka kunye neSiqinisekiso:I-PC341 ithwala isiqinisekiso se-CE kwaye isebenza ngokuthembekileyo kuluhlu olubanzi lobushushu (-20 ℃ ~ +55 ℃), ilungele iimeko zofakelo lwangaphakathi.

5. Ukuqukumbela: Imitha ye-OWON ye-WiFi Smart-IsiVumeli esiPhambili kwiinkqubo ze-Balcony PV

Iinkqubo zePV zeBalcony zijika izigidi zeebhalkhoni zokuhlala zibe "zizixhobo zamandla ezincinci." Imitha ehlakaniphile ye-WiFi njenge-OWON PC341 inceda ezi nkqubo zisebenze ngendlela “ethobelayo, ekrelekrele, ekhuselekileyo, nesebenzayo”. Idlala iindima ezibalulekileyo ezibandakanya "ukulinganisa, ukubeka iliso kunye nonxibelelwano." Ukujonga phambili, ngokwamkelwa kwamaxabiso aguquguqukayo, urhwebo lwekhabhoni, kunye ne-V2G, umsebenzi wemitha ekrelekrele uya kuvelela ngaphaya kokuhamba kombane ochasene nokubuyela umva, okunokuthi kuphuculwe ukuze ube yindawo engundoqo yenkqubo yolawulo lwamandla asekhaya, okwenza ukuba yonke i-kilowatt-iyure yombane oluhlaza ibonakale, ilawuleke, kwaye iphunyezwe, ikhanyise ngokwenene i-carbon mile ephilayo.

IThekhnoloji ye-OWON inikezela ngezisombululo ezibanzi ukusuka kwiimveliso eziqhelekileyo ze-IoT ukuya kwiinkonzo ze-ODM zesixhobo. Umgca wayo wemveliso kunye nobuchule obuchwephesha bunokuxhasa iinkqubo zePV zebalcony kunye nezicelo zolawulo lwamandla asekhaya ngokubanzi.
