Qhov Tseeb Tseem Ceeb: Tsis muaj qhov ua tsis tiav - tsuas yog qhov kev ua tau zoo ntawm qhov kev poob qis, kev txo qis los ntawm kev tsim kom zoo
Raws li lub ntiaj teb kub nce xyoo los ntawm lub xyoo, ntau tus neeg txhawj xeeb seb lub hnub ci vaj huam sib luag yuav tsis ua haujlwm thaum huab cua kub. Qhov kev txhawj xeeb no tsis tsim nyog vim tias ChuHan lub hnub ci vaj huam sib luag tseem ua haujlwm txawm tias nyob rau hauv qhov kub siab heev. Peb lub tuam txhab tsim qauv niaj hnub ua kom ntseeg tau tias peb cov khoom ua haujlwm muaj kev ntseeg siab nyob rau hauv feem ntau.
| Hom vaj huam sib luag | Kub Coefficient (ib degree) |
| ChuHan N-hom Monocrystalline | -0.30% |
| Standard Polycrystalline | -0.40% rau -0.50% |
| Nyias zaj duab xis (Amorphous Silicon) | -0.20% rau -0.32% |
| Heterojunction (HJT) | -0.24% rau -0.30% |
1.Basic Working Principple of Solar Photovoltaic Panels
Ua ntej peb pib lub ntsiab lus niaj hnub no, tej zaum koj yuav xav paub seb lub hnub ci vaj huam sib luag hloov lub hnub ci rau hauv hluav taws xob li cas. Cov lus teb yog cov nyhuv photovoltaic. Txhua lub hnub ci vaj huam sib luag muaj ntau lub hlwb uas ua haujlwm ua ke los tsim tam sim no thaum lub hnub ci tsoo lawv. Txoj kev no, koj tau txais lub zog huv ntawm lub hnub- tsis muaj qhov txav thiab tsis muaj suab nrov. Rau qhov ua tau zoo tshaj plaws, nruab hnub ci vaj huam sib luag hauv thaj chaw uas muaj hnub ci tshaj plaws, xws li lub ru tsev lossis qhib hauv av.
Tswv yim: Khaws lub hnub ci vaj huam sib luag kom huv si thiab tsis muaj kev cuam tshuam txhim kho lub zog tso zis efficiency.
1. Hom Txheej Txheem
Peb hom kev siv hluav taws xob hnub ci tseem ceeb yog:
- Daim phiaj-Tied Systems: Cov no txuas mus rau daim phiaj hauv zos. Hnub ci zog yog siv thaum nruab hnub, thiab lub zog hluav taws xob hloov mus rau hmo ntuj. Ntau lub tuam txhab nyiam qhov kev daws teeb meem no rau nws txoj kev yooj yim thiab tus nqi -kev ua tau zoo.
- Tawm -Grid Systems: Cov no ua haujlwm yam tsis muaj kab sib txuas thiab xav tau roj teeb los khaws lub zog. Haum rau tej thaj chaw deb lossis cheeb tsam uas tsis muaj zog.
- Hybrid Systems: Cov no muab ob txoj hauv kev, siv lub hnub ci zog, roj teeb, thiab kab sib chaws. Qhov no muab lub zog thaub qab thiab tso cai rau ntau lub zog siv.
| System Hom | Daim phiaj xav tau? | Roj teeb siv? | Qhov chaw tsim nyog |
|---|---|---|---|
| Daim phiaj-Tied | Yog lawm | Tsis muaj | Kev lag luam hauv nroog, thiab lwm yam. |
| Tawm -Grid | Tsis muaj | Yog lawm | Cov cheeb tsam uas tsis muaj zog, thiab lwm yam. |
| Hybrid | Yog/Tsis yog | Yog lawm | Critical infrastructure, thiab lwm yam. |
2. Cov Cheebtsam tseem ceeb ntawm lub hnub ci fais fab
Txhawm rau tsim kom muaj lub hnub ci muaj zog rau koj txoj kev lag luam, koj xav tau cov hauv qab no:
- Hnub Ci Vaj Huam Sib Luag: Sau lub hnub ci thiab tsim hluav taws xob.
- Photovoltaic Inverters: Hloov DC fais fab rau AC fais fab rau siv hauv tsev.
- Mounting Systems: suav nrog aluminium brackets, connectors, thiab lwm yam khoom siv installation kom ruaj ntseg panels, txawm nyob rau hauv huab cua hnyav.
- Lub zog cia roj teeb (yeem): Khaws lub zog ntau dhau rau kev siv tom qab.
2. Puas yog lub hnub ci vaj huam sib luag tsis nyob rau hauv siab - Huab cua kub?
Thaum xav txog seb lub hnub ci vaj huam sib luag puas nyob rau hauv huab cua kub, kuv vam khom cov ntaub ntawv tiag tiag thiab cov txiaj ntsig kev xeem. ChuHan lub hnub ci photovoltaic panels tsis poob thaum tshav kub heev-lawv tseem tsim hluav taws xob, txawm tias cov zis yuav txo qis me ntsis.
Piv txwv li, ntawm 50 degree, feem ntau cov vaj huam sib luag tseem ua haujlwm nyob ib puag ncig 90% ntawm lawv cov khoom ntsuas. Txawm tias thaum tshav kub kub, kev poob qis tsis txhais hais tias ua tsis tiav. Qhov no ua kom ruaj khov ua haujlwm rau cov neeg siv khoom lag luam hauv cov xwm txheej hnyav.
Raws li xibfwb Alastair Buckley ntawm University of Sheffield piav qhia,"Nws tsis yog qhov loj heev. Cov kub kub muaj qhov cuam tshuam me me rau tag nrho cov hnub ci tso tawm- qhov no yog qhov thib ob. Yog tias nws tshav ntuj thiab kub, koj tseem tau txais cov cim zoo. Cov zis tsis poob."
1. Cov ncauj lus kom ntxaws txog kev ua haujlwm tsis zoo
Kev ua haujlwm poob vim qhov kub thiab txias tsis tuaj yeem zam tau. Piv txwv li, yog tias qhov kub nce ntawm 25℃mus rau 60 degree, lub vaj huam sib luag nrog qhov kub thiab txias coefficient ntawm -0.30% /℃yuav poob kwv yees li 10.5% ntawm nws cov zis hluav taws xob. Kev ua tau zoo feem ntau poob los ntawm 0.3% mus rau 0.5% ib℃Celsius. Cov thev naus laus zis sib txawv (piv txwv li, PERC, TOPCon, IBC, HJT) kuj sib txawv ntawm qhov kub thiab txias efficiency poob. Zuag qhia tag nrho, cov zis hluav taws xob tuaj yeem poob los ntawm 10-15% thaum huab cua kub.
Tshaj li qhov kub thiab txias, lub hnub ci vaj huam sib luag efficiency poob kuj cuam tshuam los ntawm:
- Spectral Mismatch Poob: Hnub ci muaj photons ntawm qhov sib txawv wavelengths, tab sis tsis yog txhua tus tuaj yeem hloov mus rau hluav taws xob. Vim yog cov khoom siv semiconductor (piv txwv li, silicon) bandgap txwv, tsuas yog photons nrog lub zog saum lub bandgap tuaj yeem ua rau cov hluav taws xob zoo; low-zog photons (piv txwv li, infrared) dhau mus, thaum siab -zog photons (piv txwv li, ultraviolet) poob lub zog ntau dhau li cua sov.
- Surface Optical Poob: Thaum tshav ntuj hits lub vaj huam sib luag nto, qee lub teeb pom kev los ntawm iav, thiab qee qhov yog thaiv los ntawm pem hauv ntej hlau daim phiaj electrodes. Txawm hais tias cov vaj huam sib luag niaj hnub siv los tiv thaiv- cov coatings reflective (AR txheej) thiab cov qauv tsim zoo, kev cuam tshuam lub cev thiab kev xav tseem ua rau ~ 5% pib lub teeb poob.
- Plua plav thiab av Obstruction: Plua plav yog "neeg tua neeg uas ntsiag to" ntawm hnub ci tiam. Cov plua plav, cov noog poob, los yog paj ntoos ncaj qha thaiv lub hnub ci, txo cov kev xa tawm, thiab ua kom muaj cua sov. Hauv thaj chaw qhuav lossis muaj plua plav, kev tsis saib xyuas ntev ntev tuaj yeem ua rau 5% mus rau 20% lossis siab dua tiam neeg poob.
- Shading thiab Module Mismatch: Txawm tias me me shading (piv txwv li, los ntawm nplooj, chimneys, los yog cov tsev uas nyob ib sab) cuam tshuam rau kev ua tau zoo. Nyob rau hauv ib txwm series circuits, qhov tsis muaj zog module txwv tag nrho cov hlua cov zis tam sim no, ua rau muaj qhov tseem ceeb "cov nyhuv thoob."
- Internal Recombination thiab Resistive Losses: Thaum lub sij hawm photoconversion, ib co zoo siab electrons recombine nrog lub qhov ua ntej mus txog electrodes (recombination poob), tsis ua hauj lwm tam sim no. Tsis tas li ntawd, kev tiv thaiv ntau hauv cov hlwb thiab tiv thaiv kev tiv thaiv hauv kev xaim / soldering dissipate lub zog thaum tshav kub kub thaum sib kis.
- Ntev -Lub Sij Hawm Laus thiab Degradation: Cheebtsam ib txwm muaj hnub nyoog dhau sijhawm. Piv txwv li, encapsulant (EVA) tej zaum yuav daj nyob rau hauv lub sij hawm ntev UV raug, txo kev kis; thermal kev ntxhov siab los ntawm kev hloov pauv txhua hnub tuaj yeem ua rau micro- tawg hauv cov hlwb, ua rau lub zog qis dua.
