Kev lag luam photovoltaic thoob ntiaj teb tau loj hlob sai
Ntiaj Teb: Kev lag luam tsim hluav taws xob photovoltaic tau loj hlob sai. Txij xyoo 2010 txog 2020, qhov sib xyaw txhua xyoo kev loj hlob ntawm cov peev txheej tsim hluav taws xob tsim hluav taws xob, suav nrog cov phiaj xwm tawm, yuav yog 34%.
Xyoo 2020, Cov tuam txhab Asian suav txog 95% ntawm tag nrho cov peev txheej tsim khoom ntawm c-Si photovoltaic modules. Tuam Tshoj (Daim av loj) tuav txoj haujlwm tseem ceeb, nrog rau feem ntawm 67%. Tebchaws Europe tau koom nrog 3% ntawm kev sib koom; Tebchaws Asmeskas/Canada tau pab 2%. Xyoo 2020, Tebchaws Europe' kev faib tawm ntawm cov peev txheej tsim hluav taws xob tau nce mus txog 22%, thiab xyoo 2019 nws yog 24%. Hauv kev sib piv, Tuam Tshoj' teeb tsa lub peev xwm suav txog 33%.
Ua kom pom tseeb ntawm German kev lag luam, xyoo 2020, Lub Tebchaws Yelemees yuav suav txog kwv yees li 7.6% (53.6 GWp) ntawm lub ntiaj teb kev sib sau ua ke tsim hluav taws xob muaj peev xwm (707.5 GWp), nrog kwv yees li 2 lab lub tshuab hluav taws xob teeb tsa. Xyoo 2020, Lub Tebchaws Yelemees' lub peev xwm teeb tsa tshiab yuav yog kwv yees li 5 GWp; xyoo 2019, nws yuav yog 4 GWp. Xyoo 2020, kev tsim hluav taws xob hluav taws xob yuav npog 9.2% ntawm Lub Tebchaws Yelemees' tag nrho cov hluav taws xob xav tau, thiab txhua qhov peev txheej txuas ntxiv tau yuav suav txog li 45%.
Hnub ci cell/module ua haujlwm tau zoo
Kev sim roj teeb ua haujlwm tau sau tseg raws li 26.7% ntawm monocrystalline silicon thiab 24.4% ntawm polycrystalline silicon wafer thev naus laus zis.
Qhov ua haujlwm siab tshaj plaws ntawm cov thev naus laus zis thev naus laus zis yog 23.4% ntawm CIGS (tooj liab indium gallium selenide) thiab 21.0% ntawm CdTe (cadmium telluride) hnub ci cell. Kev sim ua haujlwm tau zoo ntawm cov roj teeb perovskite yog 25.5%, cov ntaub ntawv sau tseg.
Hauv kaum xyoo dhau los, qhov nruab nrab ua tau zoo ntawm kev lag luam silicon wafer modules tau nce los ntawm kwv yees li 15% txog 20%. Tib lub sijhawm, qhov ua tau zoo ntawm CdTe cov qauv tau nce los ntawm 9% txog 19%.
Hauv kev sim, qhov ua tau zoo tshaj plaws yog cov khoom siv monocrystalline silicon nrog qhov ua tau zoo ntawm 24.4%. Cov ntaub ntawv rhuav tshem kev ua haujlwm tau qhia tias muaj lub peev xwm los ntxiv kev ua haujlwm tau zoo ntawm qib tsim khoom.
Hauv chav kuaj mob, qhov ua tau zoo tam sim no ntawm cov khoom siv sib txuas ntau lub hnub ci hauv lub cev yog siab li 47.1%. Los ntawm kev siv cov tshuab thev naus laus zis, kev ua haujlwm tau nce mus txog 38.9%.
Lub zog rov qab los
Hauv 16 xyoo dhau los, vim txhim kho kev ua haujlwm tau zoo dua qub, ua kom cov kua roj voos me me, cov pob zeb diamond hlau pom, thiab cov khoom siv silicon loj dua, cov khoom siv ntawm silicon cells tau nqis los ntawm kwv yees li 16 grams/Wp txog li 3 grams/Wp.
Qhov chaw nyob thaj tsam txiav txim siab lub sijhawm them nyiaj rov qab ntawm cov txheej txheem photovoltaic. Nyob ntawm kev teeb tsa thev naus laus zis thiab kev ua haujlwm zoo sib xws, cov txheej txheem photovoltaic nyob sab Europe Europe yuav siv sijhawm li 1.2 xyoo los sib npaug cov khoom siv hluav taws xob, thaum cov txheej txheem photovoltaic sab qab teb tuaj yeem sib npaug cov khoom siv hluav taws xob hauv ib xyoos lossis tsawg dua.
Ib lub tshuab hluav taws xob hauv Sicily siv cov qauv siv silicon nrog lub zog them rov qab lub sijhawm kwv yees li ib xyoos thiab kev npaj ua neej nyob ntev txog 20 xyoo. Cov kab ke no tuaj yeem tsim 20 npaug zog uas xav tau los tsim cov txheej txheem no.
Inverter
Cov khoom lag luam zoo tshaj plaws inverter muaj qhov ua tau zoo ntawm 98% thiab siab dua.
Kev lag luam feem ntawm txoj hlua inverters yuav tsum yog 64%. Cov inverters no feem ntau yog siv hauv thaj chaw, kev lag luam me thiab nruab nrab kev lag luam photovoltaic cov ntawv thov qis dua 150kWp. Kev hloov pauv nruab nrab muaj kev lag luam kwv yees li ntawm 34% thiab feem ntau yog siv hauv kev lag luam loj thiab kev siv hluav taws xob. Kuj tseem muaj qhov me me (kwv yees li 1%) hauv khw uas yog microinverters (rau cov khoom siv). DC/DC hloov pauv kuj tseem hu ua" lub zog ua kom zoo&";
Cov Qauv: Digitalization, rov muab hluav taws xob, ua haujlwm tshiab rau kab sib chaws ruaj khov thiab ua kom zoo rau kev siv tus kheej; lub zog cia; siv cov khoom siv hluav taws xob tshiab (SiC lossis GaN) uas tuaj yeem ua tiav qhov ua tau zoo heev thiab tsim qauv me me; qhov siab tshaj DC txoj hlua hluav taws xob ntawm 1500V.
