PV bracketcov qauv tuaj yeem muab faib ua ob hom loj: cov qauv ruaj khov thiab cov qauv taug qab. Fixed bracket feem ntau yog qhov zoo tshaj plaws qaij lub kaum sab xis ruaj khov thiab kho tau ruaj khov. Taug qab brackets feem ntau muaj xws li tiaj tus ib leeg-axis taug qab brackets, inclined ib leeg-axis taug qab brackets thiab dual-axis taug qab brackets, uas tuaj yeem ua rau PV modules ua raws li lub hnub txoj hauj lwm txav txhua hnub, txo lub kaum sab xis ntawm lub hnub ci thiab txhim kho lub hnub ci zog. nqus tus nqi ntawm PV modules.
Cov kev xaiv tshwj xeeb ntawm lub hnub ci tracker yog ze ze rau qhov project qhov ntev, topography, kev nyab xeeb ib puag ncig thiab lwm yam, thiab feem ntau yog siv rau hauv av loj fais fab nroj tsuag. Vim hais tias faib PV tej yaam num muaj teeb meem xws li chaw txwv thiab teeb pom kev zoo, kev lag luam ntawm kev txhim kho hnub ci trackers tsis siab.
Ntawm cov hnub ci trackers, lub tiaj tus ib leeg-axis taug qab bracket muaj tus nqi siab tshaj plaws, thiab yog li siv dav. Feem ntau, nws tuaj yeem nqa tau 15% -20% nce hauv kev tsim hluav taws xob rau PV fais fab nroj tsuag, thiab txawm tias ntau tshaj 20% nce hauv kev tsim hluav taws xob hauv qee qhov chaw qis qis nrog ntau lub hnub ci.
Txawm hais tias kev siv lub hnub ci trackers yuav nce kev nqis peev thiab kev lag luam thiab cov nqi kho mob, tab sis vim yog qhov tseem ceeb ntawm kev tsim hluav taws xob, tuaj yeem ua tiav cov nqi hluav taws xob tsawg. Raws li Bloomberg Tshiab Zog, nyob rau hauv thawj ib nrab ntawm 2021, lub ntiaj teb no tus nqi nruab nrab ntawm hluav taws xob rau PV fais fab nroj tsuag tej yaam num nrog taug qab bracket system yog hais txog $ 38 / MWh, uas yog ho txo qis dua PV bracket ruaj khov tej yaam num.
Kev cuam tshuam los ntawm COVID-19 kev kis tus kab mob thiab cov nqi module, cov nqi pib ua haujlwm tau qis hauv qee thaj tsam, thaum qhov nce nqi ntawm silicon, steel thiab lwm yam khoom siv raw tau ua rau cov nqi nce ntxiv. Tag nrho cov no tau ua kom muaj kev sib tw ntawm PV fais fab nroj tsuag thiab qhov poob ntawm cov khoom lag luam. Hauv cov ntsiab lus no, tus nqi ntawm kev taug qab tus nqi ntawm kev siv hluav taws xob thiab kev txhim kho cov txiaj ntsig ntawm lub bracket yog qhov tseem ceeb.
