Yuav Siv sijhawm ntev npaum li cas kom rov qab tau cov peev txheej hauv qhov chaw nres tsheb fais fab photovoltaic?
Tom ntej no yog kev piav qhia tus kheej ntawm ib tus neeg siv uas tau nqis peev hauv qhov chaw nres tsheb photovoltaic. Cia wb mus saib ntxiv.
Nws muaj 60 Canadian Hnub Ci 500W ib leeg-pob tshab ib sab photovoltaic panels, nrog rau tag nrho qhov dav ntawm li 10 meters thiab tag nrho ntev ntawm txog 12 meters. Lub kaum sab xis ntawm lub vaj huam sib luag photovoltaic thiab lub ru tsev yog 18 degree, tig mus rau sab qab teb, thiab lub vaj huam sib luag photovoltaic yeej nyob tag nrho lub ru tsev.
Tom qab ntawd muaj sab hauv ntawm qhov chaw nres tsheb photovoltaic, uas yog cov qauv sab hauv ntawm lub chaw nres tsheb fais fab. Qhov chaw sab hauv yog qhov loj, thiab nws feem ntau yog txhawb nqa los ntawm cov hlua khi, nrog cov vents ntawm ob sab. Cov kua nplaum tsis muaj dej yog siv los ntawm cov khoom siv photovoltaic, thiab sab hauv ntawm tag nrho cov chaw nres tsheb fais fab yog kaw thiab tsis muaj dej. Cov kua nplaum tsis muaj dej kuj tseem siv tau rau cov ntsia hlau nthuav dav ntawm lub mounting bracket los tiv thaiv lub ru tsev thiab tiv thaiv dej los.
Daim phiaj-txuas inverter ntawm qhov chaw nres tsheb fais fab photovoltaic kuj tau nruab rau hauv. Qhov no yog 30-kilowatt Ginlong (Solis) inverter. Cov kab liab liab no yog cov kab hluav taws xob tso tawm ntawm photovoltaic array. Ib txheej ntawm cov kab liab thiab dub yog MPPT maub los. Nws muaj 4 cables liab thiab 4 dub cables, tab sis qhov tseeb tsuas yog siv ob lub MPPT controllers. Cov kab dub dub no yog cov kab tawm ntawm cov khoom tam sim no, thiab cov zis yog peb-theem AC.
Txuas mus rau lub thawv xa khoom, thiab tom qab ntawd dhau los ntawm lub thawv xa khoom thiab lub 'meter' mus rau daim phiaj pej xeem.
Qhov no yog ib tug raug hlua inverter. Peb xyoos dhau los, nws qhov siab tshaj plaws input voltage yog li 1,000 volts. Tam sim no muaj cov qauv ntawm txog 1,500 volts.
Inverter ntawm input voltage Lub inverter txhim kho cov input voltage, uas pab nws MPPT conversion efficiency. Cov zis interface tso tawm 380 volts AC. Lub ntsiab cable los ntawm sab saum toj yog 380 volts AC.
Tom qab ntawd nws dhau los ntawm lub thawv xa khoom photovoltaic, tom qab ntawd los ntawm lub 'meter', thiab thaum kawg tso tawm rau peb daim phiaj hluav taws xob pej xeem, ua tiav daim phiaj sib txuas. Qhov no yog kuv tsev neeg qhov chaw nres tsheb fais fab photovoltaic. Cov qauv ntawm qhov chaw nres tsheb photovoltaic faib yog qhov yooj yim yog tias nws txuas nrog daim phiaj. Nws yog tsuas yog tsim los ntawm cov khoom siv hluav taws xob photovoltaic thiab daim phiaj-txuas inverters.
Qhov chaw nres tsheb fais fab photovoltaic no tau tsim thiab txuas nrog daim phiaj nyob rau lub Yim Hli 2021, nrog rau tag nrho lub zog ntawm 29.1kw thiab tsim lub zog ntawm 30kw. Vim yog cov khoom siv teeb meem, lub zog tiag tiag yog 29.1kw. Nws raug ntsia los ntawm tus kheej peev. Tus nqi tivthaiv tau kim me ntsis thaum lub sijhawm. Tag nrho cov peev nyiaj yog 78,000 RMB. Thaum Lub Peb Hlis 2024, nws tau tsim hluav taws xob 90,244 kwh, tag nrho hauv hom online, nrog rau tag nrho cov nyiaj tau los ntawm 35,590 RMB.
Los ntawm cov ntaub ntawv saum toj no, nws tuaj yeem txiav txim siab tau yooj yim tias qhov nruab nrab cov nyiaj tau los txhua xyoo yog 14,236 RMB, thiab tus nqi tuaj yeem rov qab tau li ntawm 5.5 xyoo. Tau kawg, cov nyiaj tau los ntawm kab sib txuas yuav raug cuam tshuam los ntawm tus nqi hluav taws xob. Txawm li cas los xij, peb tuaj yeem ua kom lub zog tso tawm ntawm peb qhov chaw nres tsheb hluav taws xob sib txuas los ntawm kev saib xyuas yooj yim. Piv txwv li, nyob rau hauv daim duab saum toj no, lub Cheebtsam yog them nrog plua plav tshaj ib cheeb tsam loj. Kev tu tsis tu ncua tuaj yeem ua kom lub zog tso zis ntau dua 10%-30%.
