Lub tshuab photovoltaic cia zog yog dab tsi?
Lub tshuab khaws cia hluav taws xob photovoltaic yog kev sib xyaw ua ke ntawm cov khoom siv thiab thev naus laus zis uas hloov lub zog hnub ci mus ua hluav taws xob los muab cov khoom siv hauv tsev thaum khaws cov seem rau kev siv thaum hmo ntuj lossis thaum tsis muaj hluav taws xob.
Nws yog dab tsi thiab cov khoom tseem ceeb yog dab tsi?
1. Lub photovoltaic module: muaj ntau lub photovoltaic modules (tseem hu ua solar panels) uas yog lub luag haujlwm rau kev ntes lub hnub ci thiab hloov nws mus rau hauv hluav taws xob ncaj qha.
2. Racking, accessories thiab cables: siv los kho cov hnub ci panels thiab thauj cov DC fais fab tsim mus rau lub inverter.
3. Cov inverters (cov inverters txuas nrog grid thiab off-grid): Lub zog hloov pauv tam sim no (AC) yog tsim los ntawm kev hloov pauv lub zog tam sim no ncaj qha (DC) uas tsim los ntawm cov vaj huam sib luag hnub ci, thiab khaws cov zog ntau dhau rau hauv lub kaw lus khaws cia zog, uas kuj tuaj yeem txuas nrog lub nroog grid.
4. Cov khoom siv khaws cia hluav taws xob: Feem ntau yog hais txog cov roj teeb, xws li cov roj teeb lithium thiab lwm hom roj teeb, uas khaws cov hluav taws xob tsim los ntawm lub zog hnub ci uas tsis siv tam sim ntawd los ntawm lub inverter rau kev siv tom qab.
5. EMS thiab BMS: EMS yog lub kaw lus uas saib xyuas thiab tswj kev ua haujlwm ntawm tag nrho lub kaw lus kom ntseeg tau tias txhua qhov chaw ua haujlwm tau zoo thiab muaj kev nyab xeeb. BMS yog lub kaw lus tswj hwm lub roj teeb cia, ua kom zoo dua thiab tswj hwm kev them thiab tso tawm ntawm lub roj teeb.
6. Lub thawv sib sau ua ke: suav nrog txhua yam khoom siv tiv thaiv thiab cov hloov pauv, xws li kev tiv thaiv hluav taws xob (kev tiv thaiv xob laim) nyob nruab nrab ntawm lub hnub ci nkag mus rau hauv lub inverter, fuses, DC circuit breakers, utility input circuit breakers, uninterruptible power supply output circuit breakers thiab lwm yam.
Cov nyhuv photovoltaic, yuav ua li cas kom tau hluav taws xob los ntawm lub zog hnub ci
1. Kev nqus cov photons: Thaum lub hnub ci (suav nrog lwm lub teeb ci) ntaus cov khoom (silicon) ntawm lub hnub ci vaj huam sib luag, lub zog ntawm cov photons raug nqus los ntawm cov khoom siv semiconductor.
2. Kev txhawb nqa cov electrons: Lub zog photon uas nqus tau ua rau cov electrons hauv lub semiconductor dhia ntawm valence band mus rau conduction band, hloov lawv los ntawm lub xeev khi mus rau lub xeev dawb.
3. Kev tsim cov khub electron-hole: Thaum ib lub electron raug excited rau hauv conduction band, nws tawm hauv ib lub qhov hauv lub valence band. Lub electron thiab qhov no tsim ib khub electron-hole.
4. Tsim kom muaj hluav taws xob: P-hom thiab N-hom cheeb tsam feem ntau muaj nyob rau hauv cov ntaub ntawv photovoltaic, thiab ntawm qhov sib tshuam ntawm ob thaj tsam no (piv txwv li, qhov sib tshuam PN), ib qho hluav taws xob sab hauv yog tsim.
5. Tsav cov hluav taws xob ntws: Lub zog hluav taws xob sab hauv no tsav cov hluav taws xob dawb kom txav mus rau thaj tsam N-hom thiab cov qhov kom txav mus rau thaj tsam P-hom, thiab qhov kev txav no tsim cov hluav taws xob tam sim no.
6. Kev sau cov hluav taws xob tam sim no: Los ntawm lub inverter, cov hluav taws xob tam sim no raug hloov mus ua hluav taws xob AC lossis DC thiab khaws cia rau hauv lub kaw lus khaws cia hluav taws xob rau kev siv tom qab.
Cov inverters txuas nrog grid thiab off-grid ua haujlwm li cas thiab lawv hom kev ua haujlwm
1. Lub inverter txuas nrog lub grid hloov lub zog DC uas tsim los ntawm cov vaj huam sib luag hnub ci mus rau hauv lub zog hluav taws xob tsim nyog rau inverter los ntawm MPPT module, thiab tom qab ntawd hloov nws mus rau hauv lub zog AC los ntawm cov khoom siv hluav taws xob los muab cov khoom siv hauv tsev, thiab yog tias muaj lub zog ntau dhau, nws yuav raug hloov mus rau tib lub zog li ntawm lub kaw lus cia khoom thiab them rau hauv lub kaw lus cia khoom rau kev thaub qab, thiab yog tias muaj lub zog ntau dhau, nws yuav raug thim rov qab thiab koom ua ke rau hauv lub zog hluav taws xob grid.
2. Cov tshuab khaws cia hluav taws xob PV muaj cov hom tsim hluav taws xob thiab siv hluav taws xob, hom txo qhov siab tshaj plaws thiab hom sau cov hav, thiab hom roj teeb tseem ceeb.
Hom kev tsim hluav taws xob tus kheej thiab hom kev siv tus kheej: hluav taws xob tsim los ntawm cov vaj huam sib luag hnub ci hloov mus ua hluav taws xob hloov pauv (AC) thiab xa ncaj qha rau cov khoom siv hauv tsev, thaum qhov ntau dhau raug them rau hauv lub kaw lus cia khoom; yog tias tam sim no tsim los ntawm cov vaj huam sib luag hnub ci tsis txaus rau cov khoom siv hauv tsev siv, nws tau rov ua dua siv lub zog hluav taws xob hauv nroog.
Hom Peak Shaving thiab Valley Filling: Thaum lub sijhawm teeb tsa, lub zog AC los ntawm lub nroog grid yuav raug hloov mus ua DC zog thiab them rau hauv lub zog khaws cia; thaum lub sijhawm teeb tsa siab tshaj plaws, lub zog DC hauv lub zog khaws cia yuav raug hloov mus ua AC zog kom muab rau cov khoom siv hauv tsev; yog tias lub zog roj teeb tsis txaus, nws yuav raug ntxiv los ntawm lub nroog grid.
Hom Kev Ua Ntej Rau Roj Teeb: Txawm yog qhov xwm txheej dab tsi los xij, ua ntej xyuas kom meej tias lub zog ntawm lub kaw lus khaws cia lub zog puv, thaum lub zog hnub ci tsim ntau lub zog, nws yuav raug hloov pauv ncaj qha mus rau hauv lub zog AC rau kev siv roj teeb hauv tsev, thiab thaum lub luag haujlwm txuas grid qhib, qhov ntau dhau yuav raug ntxiv rau lub nroog grid.
Yuav tsim thiab xam pes tsawg lub hnub ci vaj huam sib luag W yuav tsum tau teeb tsa
Vaj huam sib luag hnub ci: LESSO 550W
Loj: L 2278 x 1134mm kwv yees li 2.6 sq. ft.
Qhov hnyav: 28kg
Lub zog: 550W
Cov qauv xam cheeb tsam:
Lus Cim: Txhawb cov vaj huam sib luag hnub ci hauv qab 7KW
Tag nrho lub zog ntawm lub hnub ci vaj huam sib luag: 550W * 12 = 6.6KW
Qhov chaw xav tau ntawm lub ru tsev: 12 x 2.6 sq. ft. = 31.2 sq. ft.
Kev suav txog kev tsim hluav taws xob txhua hnub:
Piv txwv li, Wenzhou, Suav teb, lub hnub ci siab tshaj plaws yog 3.77 teev, ib watt ib xyoos tsim hluav taws xob tau 1.088KWH, siv tau zoo txhua xyoo yog 1087.08 teev. Lub kaum sab xis ntawm lub teeb: 18 degrees.
Lub zog tsim hluav taws xob siab tshaj plaws txhua hnub = 6.6KW x 3.77H = 24.88KWH
Kev tsim hluav taws xob txhua xyoo = 6.6KW x 1087.08H = 7174.728KWH
