Hauv kev sib tw hnyav ntawm "grid parity" hauv kev lag luam photovoltaic, kev txhim kho tus nqi ntawm txhua kilowatt-teev ntawm hluav taws xob yog cuam tshuam nrog kev sib tw tseem ceeb ntawm cov tuam txhab. Raws li cov khoom siv tseem ceeb hauv kev tsim cov hnub ci cell modules, qhov tseeb ntawm lub platform txav ntawm lub tshuab photovoltaic hlua vuam ncaj qha cuam tshuam rau qhov zoo vuam thiab kev ua haujlwm ntau lawm. Lub granite txav platform mob siab rau photovoltaic hlua vuam tshuab, nrog nws qhov ruaj khov qhov kawg ntawm 0.5μm / xyoo, muab kev txhawb nqa kev siv tshuab rau kev txo tus nqi ib kilowatt-teev los ntawm ntau qhov ntev.
Kev ruaj khov siab ua kom ntseeg tau tias vuam raug thiab txo cov khoom pov tseg
Thaum lub sijhawm vuam txoj hlua ntawm cov hlwb photovoltaic, qhov kev hloov pauv ntawm qhov chaw vuam tuaj yeem ua rau kev sib txuas tsis zoo ntawm cov hlwb, yog li cuam tshuam rau kev ua haujlwm ntawm lub zog ntawm cov modules thiab txawm tias tsim cov khoom tsis zoo. Lub platform txav mus los ib txwm muaj kev hloov pauv ntawm qhov ntev vim muaj cov yam xws li kev hloov pauv ntawm qhov kub thiab txias thiab kev co ntawm lub cev, ua rau muaj kev hloov pauv ntawm qhov chaw vuam. Tus coefficient ntawm kev nthuav dav thermal ntawm lub platform granite tsuas yog (4-8) × 10⁻⁶ / ℃. Ua ke nrog nws cov qauv sab hauv ntom thiab sib xws, qhov ruaj khov ntawm 0.5μm / xyoo tuaj yeem ua tiav.
Piv txwv li, yog tias siv lub platform txav mus los sib xws, qhov sib txawv ntawm qhov chaw vuam uas tshwm sim los ntawm kev hloov pauv ntawm qhov ntev tshaj 0.1 hli, uas yuav ua rau qhov nrawm ntawm qhov vuam ntawm cov hlwb hnub ci nce mus txog 3%. Thaum siv cov platform ua si granite, qhov nrawm ntawm qhov vuam tuaj yeem tswj tau hauv 0.5%. Rau txhua qhov txo qis 1% ntawm qhov nrawm, ntau dua ib lab yuan ntawm cov hlwb roj teeb tuaj yeem txuag tau txhua xyoo, ncaj qha txo cov nqi tsim khoom ntawm cov khoom thiab tso lub hauv paus rau qhov poob qis ntawm tus nqi ib kilowatt-teev.
Txo qhov zaus ntawm kev saib xyuas cov khoom siv thiab txhim kho kev ua haujlwm ntawm cov khoom
Lub platform txav uas tsis ruaj khov qhov loj me yuav ua rau cov khoom sib kis hnav sai dua thiab txo qhov tseeb ntawm qhov chaw vim yog kev hloov pauv thaum siv ntev, yog li ntawd yuav tsum tau kho thiab saib xyuas cov khoom siv ntau zaus. Cov platform ua si granite, nrog lawv qhov ruaj khov zoo heev, tuaj yeem txo qhov tshwm sim ntawm cov teeb meem zoo li no.
Vim nws qhov kev hloov pauv me me ntawm 0.5μm ib xyoos, qib hnav ntawm cov khoom tseem ceeb xws li lub tshuab xa hluav taws xob thiab qhov chaw sensor ntawm lub tshuab vuam hlua raug txo qis heev. Raws li cov ntaub ntawv ntsuas tiag tiag ntawm qee lub tuam txhab tsim khoom photovoltaic, tom qab siv lub platform txav granite, lub voj voog txij nkawm ntawm lub tshuab vuam hlua tau ntev los ntawm ib hlis ib zaug mus rau ib hlis ib zaug, thiab lub sijhawm txij nkawm ib zaug kuj tau luv dua los ntawm 8 teev mus rau 3 teev. Kev txo qis ntawm qhov zaus ntawm kev txij nkawm khoom siv txhais tau tias kev ua haujlwm ntau dua thiab txo qis kev ua haujlwm thiab kev txij nkawm khoom siv. Raws li kab ntau lawm nrog lub peev xwm txhua xyoo ntawm 500MW, nws tuaj yeem nce lub sijhawm tsim khoom zoo los ntawm kwv yees li 200 teev txhua xyoo, tsim ntau lub photovoltaic modules muaj nqis ntau dua 5 lab yuan, thiab txo qis tus nqi ib kilowatt-teev.
Ntev lub neej ua haujlwm ntawm cov khoom siv thiab txo cov nqi peev
Tus nqi peev ntawm cov khoom siv photovoltaic ntau lawm yog siab, thiab lub neej ua haujlwm ntawm cov khoom siv cuam tshuam ncaj qha rau qhov rov qab los ntawm kev nqis peev ntawm cov lag luam. Vim yog kev hloov pauv mus sij hawm ntev thiab kev hloov pauv ntawm cov qauv, cov platform txav mus los feem ntau ua tsis tau raws li qhov xav tau ntau dua tsib xyoos. Yog li ntawd, cov lag luam yuav tsum hloov cov khoom siv ua ntej, ua rau muaj kev nyuaj siab ntawm kev nqis peev ruaj khov.
Cov platform ua si ntawm granite, nrog lawv cov khoom siv lub cev thiab tshuaj ruaj khov, tuaj yeem tswj tau qhov tseeb siab thaum siv ntev thiab ua kom lub neej ua haujlwm ntawm lub tshuab vuam hlua ntev dua. Cov ntaub ntawv los ntawm ib lub chaw tsim khoom siv photovoltaic qhia tau hais tias lub tshuab vuam hlua uas muaj lub platform txav granite tseem tuaj yeem tswj tau qhov tseeb ntawm qhov chaw vuam hauv ± 0.1 hli tom qab siv tas li rau 8 xyoo, ua tau raws li cov kev xav tau ntawm cov khoom siv ua haujlwm siab. Qhov sib txawv, cov khoom siv uas siv cov platform txav ib txwm yuav tsum tau hloov lawv cov khoom tseem ceeb lossis hloov kho tag nrho lub tshuab tom qab tsib xyoos. Kev txuas ntxiv ntawm lub neej ua haujlwm ntawm cov khoom siv ua rau cov nqi peev txheej ruaj khov ntawm cov lag luam raug faib rau lub sijhawm ntev dua, txo qhov feem ntawm cov khoom siv poob nqi hauv tus nqi ib kilowatt-teev.
Pab txhawb kev tsim cov khoom siv zoo thiab nce cov nyiaj tau los ntawm kev tsim hluav taws xob
Qhov ruaj khov ntawm 0.5μm / xyoo muab kev lees paub rau lub tshuab vuam txoj hlua photovoltaic kom ua tiav qhov kev vuam siab dua, ua rau cov tuam txhab tsim cov photovoltaic modules nrog kev ua haujlwm zoo dua. Hauv kev siv hluav taws xob, cov khoom siv ua haujlwm siab tuaj yeem ua tiav lub peev xwm tsim hluav taws xob siab dua thiab qis dua qhov attenuation, yog li txhim kho tag nrho cov nyiaj tau los ntawm kev tsim hluav taws xob ntawm lub chaw hluav taws xob.
Piv txwv li, cov iav ob sab uas muaj kev vuam zoo tuaj yeem ua rau lub zog tsim hluav taws xob zoo dua 3% txog 5% piv rau cov modules ib txwm muaj. Piv txwv li, lub chaw tsim hluav taws xob photovoltaic 100MW. Los ntawm kev siv cov khoom siv ua haujlwm siab, nws tuaj yeem tsim hluav taws xob ntxiv 3 txog 5 lab kilowatt-teev txhua xyoo. Kev nce ntxiv ntawm cov nyiaj tau los ntawm kev tsim hluav taws xob txhais tau tias txo qis tus nqi ib kilowatt-teev, ua rau kev lag luam thiab kev sib tw ntawm cov chaw tsim hluav taws xob photovoltaic zoo dua.
Lub platform txav granite mob siab rau cov tshuab vuam txoj hlua photovoltaic, nrog rau qhov ruaj khov ntawm 0.5μm / xyoo ua nws qhov zoo dua, txo cov nqi tsim khoom ntawm cov photovoltaic modules thiab tus nqi ib kilowatt-teev ntawm cov chaw tsim hluav taws xob los ntawm ntau txoj hauv kev xws li kev ua kom raug qhov vuam, txo cov khoom siv kho, txuas lub neej ntawm cov khoom siv, thiab pab txhawb kev tsim cov khoom siv zoo. Nws muab kev txhawb nqa kev txawj ntse rau kev lag luam photovoltaic kom ua tiav "grid parity" thiab kev txhim kho ruaj khov.
