Hauv cov tshuab hluav taws xob photovoltaic, thaum cov vaj huam sib luag hnub ci yog cov khoom pom tseeb tshaj plaws, lub kaw lus mounting hauv qab lawv yog qhov tseem ceeb rau kev ua haujlwm kom muaj kev nyab xeeb thiab ruaj khov. PV mounting systems tsis yog tsuas yog ua haujlwm los tiv thaiv cov modules xwb tab sis kuj yuav tsum hloov kho rau ntau yam kev teeb tsa ntawm qhov chaw thiab lav qhov kev ntseeg siab mus sij hawm ntev. Tsab xov xwm no muab kev tshuaj xyuas tob txog cov khoom sib xyaw, cov qauv xaiv, thiab cov yam ntxwv ntawm cov hom PV mounting systems.
1. Lub Luag Haujlwm thiab Qhov Tseem Ceeb ntawm PVCov Txheej Txheem Mounting
Lub PV mounting system (tseem hu ua PV mounting system) yog ib lub qauv hlau siv los txhim kho PV modules rau ntau qhov chaw (xws li ru tsev lossis hauv av). Nws cov khoom siv tseem ceeb yog txhuas alloy, sib npaug lub zog thiab qhov yuav tsum tau sib dua, ua rau nws tsim nyog rau cov xwm txheej uas muaj peev xwm thauj khoom ru tsev tsawg. Txawm hais tias cov mounting systems suav txog tsuas yog li 3% ntawm tag nrho cov nqi system (raws li NREL cov ntaub ntawv), lawv yog ib qho tseem ceeb uas cuam tshuam rau lub system kev nyab xeeb thiab kev ruaj khov.
2. Cov Cheebtsam Tseem Ceeb ntawm PV Mounting System
Feem ntau, ib qho PV mounting system muaj cov khoom hauv qab no:
Cov Teeb Ci Tsis Muaj Dej
Kev teeb tsa lub ru tsev yuav tsum muaj cov khoom siv tiv thaiv dej kom tsis txhob xau. Cov no feem ntau yog ua los ntawm cov ntawv txhuas thiab muab tso rau hauv qab cov shingle asphalt thaum lub sijhawm teeb tsa. Rau cov khoom siv tshwj xeeb xws li cov vuas vov tsev, hlau, lossis roj hmab, cov khoom siv tiv thaiv uas tsim tshwj xeeb yog qhov tsim nyog.
Kev Txhawb Nqa Mounts
Cov mounts yog cov khoom sib txuas ntawm lub kaw lus thiab lub ru tsev, ua kom lub flashing rau lub ru tsev rafters nrog bolts. Yuav tsum tau soj ntsuam qhov chaw ua ntej kev teeb tsa kom paub tseeb tias lub peev xwm thauj khoom thiab qhov sib nrug ntawm cov rafters ua tau raws li qhov yuav tsum tau teeb tsa.
Cov ntsia hlau
Ua lub cev pob txha rau cov modules, cov rails raug kho ntsug lossis kab rov tav rau ntawm lub ru tsev ntawm cov mounts. Tshaj li lawv txoj haujlwm txhawb nqa, lawv muab cov channel rau kev tswj hwm cable, ua kom zoo dua qhov kev nyab xeeb thiab kev zoo nkauj ntawm lub system. Ntxiv rau cov kev daws teeb meem rail ib txwm muaj, cov qauv tsim tshiab xws li rail-less thiab shared-rail systems muaj.
Cov clamps
Cov modules raug khi rau ntawm cov hlau siv cov clamps nruab nrab thiab cov clamps kawg. Cov clamps nruab nrab yog siv ntawm cov modules sib ze, thaum cov clamps kawg yog muab tso rau ntawm qhov kawg ntawm cov array thiab feem ntau muab lub zog xauv muaj zog dua.
3. Cov Yam Ntxim Saib Xyuas ntawm Cov Hom Phiaj PV Mounting
Feem ntau cov neeg teeb tsa xaiv cov hom lag luam koom tes raws li hom ru tsev. Cov hauv qab no yog cov kev daws teeb meem tseem ceeb hauv kev ua lag luam:
SnapNrack
Ib lub tuam txhab nyob hauv California, nws lub Ultra Rail Roof Mount System muaj tus qauv tsim uas yooj yim rau kev teeb tsa. Nws muab cov kev daws teeb meem hauv av thiab cov txheej txheem uas tau sib dhos ua ntej, txo lub sijhawm ua haujlwm ntawm lub ru tsev.
Unirac
Nws cov khoom lag luam npog cov xwm txheej hauv tsev thiab kev lag luam, tsim nyog rau cov ru tsev pitched, cov ru tsev tiaj tus, thiab kev teeb tsa hauv av. Tau koom nrog ntau dua 2.5 lab qhov project, nws muaj kev paub dhau los ntawm kev siv ntau yam.
IronRidge
Nws lub ru tsev uas muaj lub zog zoo heev tau raug sim hauv cov chaw muaj cua daj cua dub loj heev hauv Florida. Nws tau ua haujlwm txij li xyoo 1990, thiab nws muaj cov txiaj ntsig zoo hauv kev tiv thaiv cua thiab kev tiv thaiv xeb.
Kev Teeb Tsa PV Sai thiab EcoFasten
Tsom ntsoov rau cov kev daws teeb meem rau cov ru tsev tshwj xeeb:
Cov Ru Tsev Hlau Uas Muaj Qhov Txuas: Siv cov thev naus laus zis uas tsis nkag mus rau hauv, txuas ncaj qha rau cov qhov txuas ntawm lub ru tsev, tshem tawm cov kev pheej hmoo ntawm kev xau thiab txhim kho kev teeb tsa zoo.
Cov Ru Tsev Av nplaum/Spanish Tile: Tsim cov vuas hloov uas hloov cov vuas ru tsev uas twb muaj lawm thaum tseem muab cov dej tsis nkag, zam kev puas tsuaj rau cov khoom tawg yooj yim.
Txhua Lub Ntiaj Teb Rov Ua Dua Tshiab
Tshwj xeeb hauv cov txheej txheem taug qab uas tau teeb tsa hauv av. Siv cov thev naus laus zis taug qab ob txoj kab ke, cov txheej txheem no ua rau cov modules ua raws li txoj kev ntawm lub hnub hauv lub sijhawm tiag tiag, ua rau muaj zog ntau dua 20-40% piv rau cov txheej txheem ruaj khov, ua rau lawv haum rau cov haujlwm uas muaj qhov chaw dav thiab tsom mus rau kev ua haujlwm zoo.
4. Cov Kev Xav Tseem Ceeb rauKev Teeb TsaKev Xaiv
Kev Sib Haum Xeeb ntawm Lub Ru Tsev: Qhov kev xaiv yuav tsum sib haum rau cov khoom siv ntawm lub ru tsev (asphalt shingle/hlau/av nplaum, thiab lwm yam), qhov nqes hav, thiab lub peev xwm thauj khoom ntawm cov qauv.
Kev Tsim Kev Tiv Thaiv Dej Thiab Kev Nqus Dej: Kev teeb tsa uas nkag mus rau hauv yuav tsum ua kom ntseeg tau tias muaj qib siab ntawm kev tiv thaiv dej, thaum cov tshuaj uas tsis nkag mus rau hauv yuav tsum tau lees paub qhov kev quab yuam clamping thiab kev sib xws ntawm lub ru tsev.
Kev Tswj Xyuas Cable: Kev tsim cov tais cable sib xyaw ua ke cuam tshuam rau kev huv si thiab kev yooj yim txij nkawm.
Cua thiab Daus Thauj Khoom: Yuav tsum ua raws li cov cai hauv zos thiab cov qauv tsim kom tiv taus cua thiab daus.
Kev Ua Haujlwm Zoo ntawm Kev Teeb Tsa: Kev tsim qauv modular thiab kev muaj peev xwm ua ntej sib dhos hauv av muaj feem cuam tshuam rau lub sijhawm tsim kho.
Xaus lus
Raws li qhov txuas tseem ceeb txuas cov chaw tsim hluav taws xob rau lub tsev, kev xaiv lub tshuab PV mounting cuam tshuam ncaj qha rau kev nyab xeeb ua haujlwm thiab kev ua haujlwm tau zoo thoob plaws lub voj voog 25 xyoo ntawm lub tshuab. Nws raug pom zoo kom cov tswv yuav tsum xub xaiv cov neeg teeb tsa uas muaj peev xwm tsim qauv tshaj lij thiab kev koom tes tsim nyog nrog cov npe nrov, kom ntseeg tau tias kev sib koom ua ke zoo meej ntawm lub tshuab PV nrog ib puag ncig ntawm lub tsev los ntawm kev daws teeb meem kev teeb tsa.
(Tsab xov xwm no yog sau ua ke raws li cov qauv kev lag luam PV thiab cov ntaub ntawv pej xeem ntawm cov chaw tsim khoom; cov kev daws teeb meem tshwj xeeb yuav tsum tau txiav txim siab tom qab kev tshuaj xyuas ntawm qhov chaw.)
