Tshaj tawm ntawm hnub ci zog
Nrog bifacial modules ua ntau commonplace, mounting tshuab tau kom sai sai rau ib tug tshiab tsim. Txij li cov khoom tau los ntawm cov khoom siv hauv bifacial yuav tshwj xeeb tshaj yog siab nrog kev soj ntsuam tshuab, manufacturers tau hloov lawv lub tshuab kom tau raws li kev thov.
Feem coob ntawm cov kev sib tw yog ib qho uas muaj peev xwm pab tau rau cov kev sib tw, kev sib txuas lus, thiab kev sib txuas lus.
Soltec tau qhia tshwj xeeb uas formulated nws cov SF7 Bifacial tracker kom siab (mus ntes ntau dua kev sib tw), thiab cov khoom siv hauv ob lub ntsiab lus-kev xaiv kom tsis txhob backside shading losses. Arctech Hnub Ci lub SkySmart nrhiav qhov system kuj qhia tshwj xeeb uas yog tsim los rau cov khoom siv hauv nruab siab thiab siv plaub- lossis rau-clamp mounting los txo cov kev lag luam rov qab.
NEXTracker 's NX Horizon ib-kab ntsig tracker nta PV panels portrait-mounted ntawm kev sib tw qes profile, dav dav ntawm qhov module rov qab thiab hloov torque tub ntxhais, ntxiv tsis muaj lub hauv paus pier thiab array bearing placement hauv lub PV panels. Cov ntsiab lus tsim no pab kom muaj peev xwm ua kom muaj zog ntau tshaj plaws rau cov chaw sib tw. NEXTracker tseem qhia txog kev tsim tshwj xeeb rau cov neeg siv kev siv tshuab bifacial, uas yog muaj kev ua kom zoo siab thiab cov av hauv qhov av.
"Tsis tas li ntawd, NX Horizon txoj kev taug mus dav dav ntxiv txhim kho qhov kev ua tiav," said NEXTracker CMO Mike Mehawich. "Nrog 120 ° ntawm kev sib hloov, qhov backside ntawm tus module yuav ntes tau thim rov qab dua lub sij hawm txhua hnub."
Array Technologies tus thawj coj ntawm engineering Mark Preston hais tias lub tuam txhab tawm tswv yim los tso tawm ib tus neeg nruab nrab ntawm kev sib tw ua ntej thaum xaus rau xyoo 2018. Array Technologies yog qhov sib txawv ntawm cov qauv tsim kom haum rau cov khoom siv hauv tsev kawm ntawv, nrog rau kev sib hloov mus txog qhov kev tshawb nrhiav algorithm.
"Taw tes [panels] thaum lub hnub tsis yog qhov khoom siv ntau tshaj plaws rau cov kev sib tw," Preston said.
Ib qho ntxiv uas tej zaum yuav tsis pom nrog lub nruab nrhau kev sib txuas lus yog tias ob sab ntawm cov qauv yuav tsum tau muab ntxuav tas mus rau optimize ntau lawm.
"NEXTracker tus kheej ywm ua kom yooj yim dua [kom huv] vim peb tuaj yeem tig cov npoo uas nyob ib sab ntawm lub ntsej muag los yog rov qab-rov-nrawm nrog yooj yim, thiab tsis muaj kev sib txuas thaiv cov kab," Mehawich said.
Cov khoom siv Bifacial module Trina Hnub ci tau ua tiav kev sib tw ntawm cov khoom siv hauv bifaj thiab pom tias thaum txuas mus rau ib tug tracker thiab ntawm ib sab dawb-pleev xim, cov khoom siv rau kev sib tw muab 33.2% ntau dua cov kev cai ntawm cov kab ntawm cov monofacial. Trina pom tias cov khoom siv hauv bifacial rau ntawm tus neeg taug qab tshaj xuab zeb muaj ib qho 24.42% zog nce.
Trackers uas tuaj yeem pab txhawb kev sib tw nrog lub cev muaj peev xwm ua tau kom muaj peev xwm ua tau kom ROI ceev. Mehawich nrog NEXTracker kwv yees hais tias ib tug loj npaum li cas ntawm lub khw yuav pairing bifacial modules nrog ib-axis trackers sai sai no.
"Bifacial yog qhov zoo tshaj plaws ntawm ib tus neeg nruab nrab ntawm qhov kev taug lw, thiab qhov no yuav siv sij hawm ntau ntawm qhov kev ua lag luam," nws hais. "Nrog lub dav av npog npog piv los ntawm tus neeg nruab nrab thiab nrog lub hnub ci ntawm lub ntiaj teb, hnub kawg ntawm qhov kawg tau txais [ntau tshaj plaws nrog cov khoom noj]."
