Thaum muaj coob tus neeg yuav nruab ib lub tshuab hluav taws xob photovoltaic rau ntawm lawv lub ru tsev, lawv yeej ib txwm tawm tsam nrog cov lus nug: nws puas yuav tsum txuas nrog daim phiaj lossis tawm - kab sib chaws, thiab kuv puas xav tau lub roj teeb? Hnub no, kuv yuav qhia rau koj paub qhov txawv ntawm ob.
Hauv cov ntsiab lus yooj yim:
Lub off{0}}daim phiaj photovoltaic system khaws lub hnub ci zog hauv lub roj teeb, thiab tom qab ntawd hloov mus rau hauv tsev 220V / 380V voltage los ntawm inverter.
The grid-connected photovoltaic system can also be roughly understood from the name. It refers to the connection with the mains. The grid-connected photovoltaic system has no electric energy storage device, and is directly converted into the voltage required by the national grid through the inverter, and is given priority to households. Use, the electricity that households can't use up can be sold to the state.
Tam sim no, lub teb chaws txoj cai txhawb nqa thiab txhawb nqa lub hnub ci photovoltaic system. Tsuav yog lub tsev photovoltaic system tsim hluav taws xob, yuav muaj cov nyiaj pab hauv xeev. Txawm li cas los xij, yog tias koj xav txuas rau daim phiaj, koj yuav tsum xub ua ntawv thov mus rau lub chaw haujlwm hauv lub tebchaws.
Qhov txawv tshwj xeeb:
Daim phiaj- txuas photovoltaic system
Daim phiaj - txuas txhais tau hais tias nws yuav tsum tau txuas nrog daim phiaj pej xeem, uas yog, lub hnub ci, daim phiaj hauv tsev, thiab daim phiaj pej xeem txuas ua ke. Qhov no yog lub zog hluav taws xob uas yuav tsum tau tso siab rau daim phiaj uas twb muaj lawm los ua haujlwm.
Nws yog tsim los ntawm cov hnub ci vaj huam sib luag thiab inverter. Cov zis ntawm lub hnub ci vaj huam sib luag yog ncaj qha hloov mus rau 220V / 380V AC lub zog los ntawm inverter thiab muab lub zog rau cov khoom siv hauv tsev. Thaum lub zog tsim los ntawm lub hnub ci zog tshaj lub zog siv los ntawm cov khoom siv hauv tsev, cov hluav taws xob ntau dhau yuav raug xa mus. Rau pej xeem daim phiaj; thiab thaum lub hnub ci tsis tuaj yeem ua tau raws li kev siv cov khoom siv hauv tsev, nws tau txais kev ntxiv los ntawm daim phiaj. Thiab tag nrho cov txheej txheem no yog tswj kom ntse thiab tsis tas yuav tsum tau ua haujlwm.
Txij li cov txheej txheem photovoltaic no tsis tas yuav siv cov roj teeb, tus nqi tau txais txiaj ntsig zoo heev. Tshwj xeeb, daim phiaj tshiab- txoj cai sib txuas tau tshaj tawm los ntawm lub xeev tau hais meej meej tias cov tshuab photovoltaic hauv tsev tuaj yeem txuas nrog rau kab hluav taws xob dawb, thiab hluav taws xob ntau dhau kuj tuaj yeem muag rau cov tuam txhab hluav taws xob. Los ntawm lub sijhawm ntev - qhov kev xav ntawm kev nqis peev, raws li 25- xyoo kev pab cuam lub neej ntawm tsev neeg photovoltaic system, tus nqi tuaj yeem rov qab tau nyob rau hauv li 5 xyoo, thiab 20 xyoo ntxiv tau txais. Yog li ntawd, yog tias koj xav txuag hluav taws xob cov nqi hluav taws xob thiab muab cov khoom siv hluav taws xob yooj yim, koj yuav tsum xaiv cov kab hluav taws xob txuas nrog lub hnub ci, uas yog txoj hauv kev tseem ceeb tam sim no.
Tawm - daim phiaj photovoltaic system
Qhov no tseem hu ua kev ywj pheej photovoltaic system. Nws yog lub zog tsim hluav taws xob uas ua haujlwm ntawm nws tus kheej yam tsis muaj kev vam khom rau ntawm daim phiaj. Nws yog tsim los ntawm cov hnub ci vaj huam sib luag, lub zog cia roj teeb, them nyiaj thiab tso tawm cov tswj, inverters thiab lwm yam khoom. Cov hluav taws xob tso tawm los ntawm lub hnub ci vaj huam sib luag ncaj qha ntws mus rau hauv lub roj teeb thiab khaws cia. Thaum nws yog ib qho tsim nyog los muab lub zog rau cov khoom siv hluav taws xob, DC tam sim no hauv lub roj teeb hloov mus rau 220V AC los ntawm inverter, uas yog lub voj voog rov ua dua ntawm cov nqi thiab tawm. Txij li thaum lub zog hluav taws xob no tsis txwv los ntawm cheeb tsam, nws yog dav siv thiab tuaj yeem ntsia tau thiab siv tau ntev npaum li muaj hnub ci. Yog li ntawd, nws yog qhov tsim nyog rau thaj chaw deb uas tsis muaj hluav taws xob sib txuas, cov Islands tuaj sib cais, cov nkoj nuv ntses, cov chaw yug tsiaj sab nraum zoov, thiab lwm yam, thiab tseem tuaj yeem siv ua hluav taws xob ntau zaus. Cov khoom siv hluav taws xob tsim hluav taws xob hauv cheeb tsam thaum muaj xwm ceev.
This kind of system must be equipped with batteries and occupies 30-50 percent of the cost of the power system. Moreover, the service life of the battery is generally 3-5 years, and it has to be replaced after that, which increases the cost of use. In terms of economy, it is difficult to be popularized and used on a large scale, so it is not suitable for use in places where electricity is convenient.
Txawm li cas los xij, nws yog qhov ua tau zoo heev rau cov tsev neeg hauv thaj chaw tsis muaj hluav taws xob lossis thaj chaw uas muaj hluav taws xob nquag. Tshwj xeeb tshaj yog txhawm rau txhawm rau daws teeb meem teeb pom kev zoo thaum muaj hluav taws xob hluav taws xob, DC lub zog - txuag teeb siv tau, uas yog qhov ua tau zoo heev. Yog li ntawd, off-daim phiaj hluav taws xob tsim hluav taws xob tau tsim tshwj xeeb rau kev siv hauv thaj chaw tsis muaj hluav taws xob lossis thaj chaw uas muaj hluav taws xob tsis tu ncua.
