Phau Ntawv Qhia Pib Pib rau PV/Energy Storage Industry

Ntau tus neeg hnov ​​​​"photovoltaic" lossis "lub zog cia" thiab tam sim ntawd xav txog qib siab - thev naus laus zis kev lag luam nrog cov kev txwv tsis pub nkag. Hauv kev muaj tiag, nws tsis yog qhov nyuaj.

Tsab ntawv xov xwm no yuav coj koj los ntawm kos rau hauv txoj kev yooj yim tshaj plaws, yooj yim tshaj plaws - piav qhia seb lub tshuab hluav taws xob photovoltaic yog dab tsi, lub zog txuag hluav taws xob yog dab tsi, lawv ua haujlwm li cas, thiab cov txiaj ntsig uas lawv coj los rau lub neej niaj hnub thiab kev lag luam.

Tsis xav tau kev txawj ntse ua ntej. Tom qab nyeem tsab xov xwm no, koj yuav tau txais kev nkag siab meej, kev nkag siab ntawm qhov kev lag luam no.

Ua ntej dhia mus rau hauv kev lag luam, tuav ob lo lus tseem ceeb: photovoltaics thiab lub zog cia.

1. Photovoltaics yog dab tsi?

Kev tsim hluav taws xob photovoltaic, yooj yim muab, yog "siv hnub ci los tsim hluav taws xob."

Cov hnub ci xiav xiav uas koj nquag pom ntawm lub ru tsev yog photovoltaic modules, tsim los hloov lub hnub ci rau hauv hluav taws xob.

Xav txog qhov no:

Photovoltaics zoo li txhim kho "lub hnub ci hluav taws xob" ntawm koj lub tsev- ntev npaum li lub hnub ci, nws tsis tu ncua ua hluav taws xob.

Cov txiaj ntsig tseem ceeb ntawm kev tsim hluav taws xob photovoltaic yog:

Tsis xav tau roj

Zero pa phem emissions

Cov nqi khiav haujlwm tsawg

Kev saib xyuas yooj yim

Tias yog vim li cas ntau thiab ntau lub tsev, cov chaw tsim khoom, thiab cov khw muag khoom tam sim no txhim kho cov tshuab photovoltaic.

2. Lub zog cia yog dab tsi?

Lub luag haujlwm tseem ceeb ntawm lub zog cia yog khaws cia hluav taws xob.

Kev tsim hluav taws xob photovoltaic muaj cov yam ntxwv sib txawv:

Nws tsuas tuaj yeem tsim hluav taws xob thaum nruab hnub nrig thaum lub hnub tawm. Thaum tsaus ntuj lossis hnub huab cua, lub zog tsim hluav taws xob txo qis lossis tseem nres tag nrho.

Txawm li cas los xij, peb qhov kev thov hluav taws xob tsis tu ncua nyob ib ncig ntawm lub moos. Qhov no tsim qhov tsis sib haum xeeb ntawm "lub sijhawm tsim hluav taws xob" thiab "lub sijhawm siv hluav taws xob."

Lub luag haujlwm ntawm lub zog cia tshuab yog:

Khaws cov hluav taws xob ntau dhau uas tsim tawm thaum nruab hnub

Tom qab ntawd tso nws thaum yav tsaus ntuj lossis lub sijhawm noj ntau tshaj

Xav txog lub zog cia li "lub txhab nyiaj loj loj" tshwj xeeb tsim los tswj thiab faib hluav taws xob.

3. Vim li cas thiaj muab photovoltaics nrog lub zog cia?

Siv photovoltaics ib leeg txhais tau tias hluav taws xob tsuas muaj thaum lub hnub ci ntsa iab;

Siv lub zog cia ib leeg txhais tau tias nws tsuas tuaj yeem khaws hluav taws xob los ntawm daim phiaj.

Kev sib xyaw ua ke "photovoltaics + lub zog cia" ua rau:

Kev siv hluav taws xob photovoltaic ncaj qha thaum nruab hnub

Khaws cov hluav taws xob ntau dhau hauv cov roj teeb
