Peb hom kev siv lub hnub ci tseem ceeb: On-Grid, Off-Grid thiab Hybrid

Peb hom tseem ceeb ntawm lub hnub ci fais fab

1. On-grid - tseem hu ua grid-tie lossis grid-feed hnub ci system

2. Off-grid - tseem hu ua stand-alone fais fab system (SAPS)

3. Hybrid - daim phiaj-txuas hnub ci system nrog roj teeb cia

Cov Cheebtsam Tseem Ceeb Ntawm Lub Hnub Ci

Hnub Ci Vaj Huam Sib Luag

Cov hnub ci hnub ci niaj hnub no feem ntau yog tsim los ntawm ntau cov silicon-based photovoltaic cells (PV cells) uas tsim hluav taws xob tam sim no (DC) hluav taws xob los ntawm tshav ntuj. Hnub ci vaj huam sib luag, tseem hu ua hnub ci modules, feem ntau txuas nrog 'cov hlua' los tsim qhov hu ua hnub ci array. Tus nqi ntawm lub hnub ci hluav taws xob tsim nyob ntawm ntau yam, suav nrog kev taw qhia thiab qaij lub kaum sab xis ntawm lub hnub ci vaj huam sib luag, kev ua haujlwm ntawm lub hnub ci vaj huam sib luag, ntxiv rau cov kev poob vim yog shading, av thiab txawm tias qhov kub thiab txias.

Hnub ci vaj huam sib luag tuaj yeem tsim lub zog thaum huab cua huab cua thiab huab cua huab cua, tab sis lub zog npaum li cas nyob ntawm 'thickness' thiab qhov siab ntawm huab, uas txiav txim siab seb lub teeb tuaj yeem dhau los ntawm ntau npaum li cas. Tus nqi ntawm lub teeb lub zog yog lub npe hu ua hnub ci irradiation thiab feem ntau yog nruab nrab ntawm tag nrho ib hnub siv lub sij hawm Peak Sun Teev (PSH). PSH los yog nruab nrab hnub ci teev nyob rau hauv feem ntau nyob ntawm qhov chaw thiab lub sij hawm ntawm lub xyoo.

Hnub ci Inverter

Hnub ci vaj huam sib luag tsim hluav taws xob DC, uas yuav tsum tau hloov mus rau alternating tam sim no (AC) hluav taws xob siv rau hauv peb lub tsev thiab kev lag luam. Qhov no yog lub luag haujlwm tseem ceeb ntawm lub hnub ci inverter. Hauv 'txoj hlua' inverter system, lub hnub ci vaj huam sib luag tau txuas ua ke ua ke, thiab DC hluav taws xob raug coj mus rau lub inverter, uas hloov lub zog DC rau AC zog. Hauv microinverter system, txhua lub vaj huam sib luag muaj nws tus kheej micro-inverter txuas rau sab nraub qaum ntawm lub vaj huam sib luag. Lub vaj huam sib luag tseem tsim tawm DC tab sis tau hloov mus rau AC ntawm lub ru tsev thiab raug pub ncaj qha rau cov hluav taws xob hloov hluav taws xob.

Kuj tseem muaj ntau txoj hlua inverter tshuab uas siv me me fais fab optimisers txuas rau sab nraum qab ntawm txhua lub hnub ci vaj huam sib luag 

Roj teeb

Cov roj teeb uas siv rau hnub ci zog cia muaj nyob rau hauv ob hom loj: lead-acid (AGM & Gel) thiab lithium-ion. Ob peb lwm hom muaj, xws li redox flow batteries thiab sodium-ion, tab sis peb yuav tsom mus rau ob qho tib si. Feem ntau niaj hnub lub zog cia tshuab siv cov roj teeb lithium-ion rechargeable thiab muaj nyob rau hauv ntau cov duab thiab ntau thiab tsawg, uas tuaj yeem teeb tsa hauv ntau txoj hauv kev piav qhia ntau ntxiv ntawm no.

Lub peev xwm roj teeb feem ntau ntsuas raws li Amp teev (Ah) rau cov hmoov lead-acid lossis kilowatt teev (kWh) rau lithium-ion. Txawm li cas los xij, tsis yog txhua lub peev xwm muaj rau siv. Cov roj teeb lithium-ion feem ntau tuaj yeem muab tau txog li 90% ntawm lawv lub peev xwm nyob rau ib hnub. Hauv kev sib piv, cov roj teeb txhuas-acid feem ntau tsuas yog muab 30% mus rau 40% ntawm lawv lub peev xwm tag nrho ib hnub kom nce roj teeb lub neej. Lead-acid roj teeb tuaj yeem tso tawm tag nrho, tab sis qhov no tsuas yog yuav tsum tau ua thaum muaj xwm txheej ceev
