Pib los ntawm 2022, n-hom hlwb thiab module technologies tau txais kev saib xyuas los ntawm ntau lub zog peev kev lag luam, nrog rau lawv cov kev lag luam sib faib tsis tu ncua.Xyoo 2023, raws li kev txheeb cais los ntawm Sobey Consulting, kev muag khoom feem ntawm n-hom technologies nyob rau hauv feem ntau cov tuam txhab photovoltaic feem ntau tshaj 30%, nrog rau qee lub tuam txhab txawm tias tshaj 60%.Ntxiv mus, tsis muaj tsawg tshaj li 15 lub tuam txhab photovoltaic tau qhia meej lub hom phiaj ntawm "ua kom dhau 60% kev muag khoom feem rau cov khoom n-hom los ntawm 2024".
Hais txog kev siv tshuab, kev xaiv rau feem ntau cov tuam txhab yog n-hom TOPCon, txawm tias qee tus tau xaiv rau n-hom HJT lossis BC thev naus laus zis daws teeb meem.Cov kev siv thev naus laus zis twg thiab cov khoom siv ua ke zoo li cas tuaj yeem ua rau muaj kev tsim hluav taws xob ntau dua, tsim hluav taws xob ntau dua, thiab cov nqi hluav taws xob qis dua?Qhov no tsis yog tsuas yog cuam tshuam rau kev txiav txim siab peev txheej ntawm cov lag luam tab sis tseem cuam tshuam rau kev xaiv ntawm cov tuam txhab lag luam fais fab thaum lub sij hawm sib tw.
Thaum Lub Peb Hlis 28th, Lub Tebchaws Photovoltaic thiab Lub Zog Cia Cia Ua Si Platform (Daqing Base) tau tshaj tawm cov ntaub ntawv tshwm sim rau xyoo 2023, txhawm rau nthuav tawm cov kev ua tau zoo ntawm cov khoom sib txawv, cov qauv, thiab cov khoom siv thev naus laus zis hauv kev ua haujlwm tiag tiag.Qhov no yog los muab cov ntaub ntawv txhawb nqa thiab kev taw qhia kev lag luam rau kev nce qib thiab kev siv cov thev naus laus zis tshiab, cov khoom tshiab, thiab cov ntaub ntawv tshiab, yog li pab txhawb cov khoom lag luam iteration thiab hloov kho dua tshiab.
Xie Xiaoping, tus thawj coj ntawm lub platform pawg kws qhia ntawv, tau taw qhia hauv tsab ntawv ceeb toom:
Meteorological thiab irradiation yam:
irradiation nyob rau hauv 2023 yog qis dua tib lub sij hawm nyob rau hauv 2022, nrog rau ob qho tib si kab rov tav thiab inclined nto (45 °) muaj ib tug 4% txo;Lub sijhawm ua haujlwm txhua xyoo nyob rau hauv qis irradiation tau ntev dua, nrog rau kev ua haujlwm qis dua 400W / m² accounting rau 53% ntawm lub sijhawm;txhua xyoo kab rov tav nto backside irradiation suav txog 19%, thiab inclined nto (45 °) backside irradiation yog 14%, uas yog qhov tseem ceeb tib yam li xyoo 2022.
Module nam:
n-type high-efficiency modules muaj kev tsim hluav taws xob zoo tshaj plaws, ua raws li cov qauv hauv 2022. Hais txog lub zog tsim hluav taws xob ib megawatt, TOPCon thiab IBC feem ntau yog 2.87% thiab 1.71% siab dua PERC;loj-loj modules muaj superior zog, nrog rau qhov sib txawv loj tshaj plaws nyob rau hauv lub hwj chim tiam yog hais txog 2.8%;muaj qhov sib txawv ntawm cov txheej txheem kev tswj hwm zoo ntawm cov tuam txhab, ua rau muaj qhov sib txawv tseem ceeb hauv kev tsim hluav taws xob ua haujlwm ntawm modules.Lub zog tsim hluav taws xob sib txawv ntawm tib lub thev naus laus zis los ntawm cov tuam txhab sib txawv tuaj yeem muaj ntau npaum li 1.63%;Feem ntau cov tuam txhab lag luam 'degradation tus nqi tau ua raws li "Specifications for the Photovoltaic Manufacturing Industry (2021 Edition)," tab sis qee qhov tshaj li cov txheej txheem;qhov degradation tus nqi ntawm n-hom high-efficiency modules qis dua, nrog TOPCon degrading ntawm 1.57-2.51%, IBC degrading ntawm 0.89-1.35%, PERC degrading ntawm 1.54-4.01%, thiab HJT degrading mus txog 8.82% vim qhov tsis ruaj khov. ntawm amorphous technology.
Inverter yam:
Cov qauv tsim hluav taws xob sib txawv ntawm cov tshuab thev naus laus zis sib txawv tau ua raws li ob xyoos dhau los, nrog cov hlua inverters tsim lub zog siab tshaj plaws, yog 1.04% thiab 2.33% siab tshaj qhov nruab nrab thiab faib cov inverters, feem;qhov ua tau zoo ntawm cov tshuab sib txawv thiab cov chaw tsim khoom inverters yog nyob ib ncig ntawm 98.45%, nrog rau IGBT hauv tsev thiab IGBT inverters uas muaj qhov sib txawv ntawm qhov sib txawv ntawm 0.01% nyob rau hauv cov khoom sib txawv.
Kev them nyiaj yug qauv nam:
Cov kev txhawb nqa taug qab tau muaj lub zog zoo tshaj plaws.Piv nrog rau kev txhawb nqa ruaj khov, kev taug qab dual-axis txhawb nqa lub zog tsim los ntawm 26.52%, ntsug ib leeg-axis txhawb nqa los ntawm 19.37%, inclined ib leeg-axis txhawb nqa los ntawm 19.36%, tiaj tus ib leeg (nrog 10 ° qaij) los ntawm 15.77%, omni-directional kev txhawb nqa los ntawm 12.26%, thiab ruaj khov kho txhawb los ntawm 4.41%.Lub zog tsim hluav taws xob ntawm ntau hom kev txhawb nqa tau cuam tshuam rau lub caij nyoog.
Photovoltaic system nta:
Peb hom kev tsim qauv nrog lub zog siab tshaj plaws yog tag nrho cov dual-axis trackers + bifacial modules + string inverters, tiaj tus ib leeg-axis (nrog 10 ° qaij) txhawb nqa + bifacial modules + hlua inverters, thiab inclined ib leeg-axis txhawb + ob-facial modules + hlua inverter.
Raws li cov ntaub ntawv saum toj no, Xie Xiaoping tau ua ntau lub tswv yim, suav nrog kev txhim kho qhov tseeb ntawm photovoltaic fais fab kev kwv yees, optimizing tus naj npawb ntawm cov qauv hauv ib txoj hlua kom ua kom cov cuab yeej ua tau zoo tshaj plaws, txhawb nqa ib leeg-axis trackers nrog qaij nyob rau hauv high-latitude txias- Cov cheeb tsam kub, txhim kho cov khoom sib khi thiab cov txheej txheem ntawm Heterojunction cells, optimizing cov kev ntsuas tsis zoo rau bifacial module system tsim hluav taws xob, thiab txhim kho cov qauv tsim thiab kev ua haujlwm ntawm cov chaw cia khoom photovoltaic.
Nws tau qhia tias National Photovoltaic thiab Energy Storage Demonstration Platform (Daqing Base) tau npaj txog 640 qhov kev sim schemes thaum lub sijhawm "Tshaj Plaub Tsib Xyoo" lub sijhawm, tsis muaj tsawg dua 100 schemes hauv ib xyoos, txhais mus rau qhov ntsuas ntawm kwv yees li 1050MW.Lub sijhawm thib ob ntawm lub hauv paus tau tsim ua tiav thaum Lub Rau Hli 2023, nrog rau kev npaj ua haujlwm puv sijhawm hauv lub Peb Hlis 2024, thiab theem thib peb tau pib tsim kho thaum Lub Yim Hli 2023, nrog cov txheej txheem tsim ua tiav thiab muaj peev xwm ua haujlwm tau zoo los ntawm qhov kawg ntawm 2024.
