Hnub ci hluav taws xob txoj kev teeb pom kev zoo rau ob lub nroog thiab nyob deb nroog. Nws yog ib qho kev tsim khoom zoo rau kev teeb pom kev sab nraum zoov, uas daws cov teeb meem tsis txaus. Lub hnub ci zog yog lub zog txuag thiab inexhaustible. Lub neej ntev ntawm lub hnub ci roj teeb zoo heev cuam tshuam rau lub neej ntawm lub hnub ci zog txoj kev teeb. Tab sis ntxiv rau cov roj teeb, kev ua haujlwm ntawm lub hnub ci vaj huam sib luag kuj txiav txim siab them lub peev xwm ntawm lub hnub ci hluav taws xob txoj kev teeb. Hnub ci vaj huam sib luag, tseem hu ua "solar chips" lossis "photocells" thiab "solar cells", yog photoelectric semiconductor nplooj ntawv uas siv lub hnub ci teeb ncaj qha los tsim hluav taws xob. Ib lub cuab yeej uas ncaj qha hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob los ntawm cov nyhuv photoelectric lossis photochemical nyhuv. Nyob rau hauv physics, nws yog hu ua photovoltaic (Photovoltaic, abbreviated li PV), los yog photovoltaic luv luv. Xaiv cov nqi siv hluav taws xob zoo hnub ci tseem ceeb heev. Peb tau sau cov ntsiab lus hauv qab no thiab qhia koj yuav ua li cas xaiv cov hnub ci vaj huam sib luag kev yuav khoom hnub ci fais fab txoj kev teeb.
1. Xaiv qhov zoo ntawm lub hnub ci vaj huam sib luag
Muaj ntau ntau hom hnub ci vaj huam sib luag, uas tuaj yeem muab faib ua monocrystalline silicon, polycrystalline silicon, thiab amorphous silicon/thin film roj teeb. Monocrystalline silicon hnub ci vaj huam sib luag muaj kev ua haujlwm siab, feem ntau 18-23 feem pua , thiab tsis tshua muaj lub teeb attenuation, tab sis lawv kim heev. Lub neej ntev ntawm monocrystalline silicon solar panels feem ntau yog ntau tshaj 25 xyoo. Kev ua tau zoo ntawm polycrystalline silicon hnub ci vaj huam sib luag yog qhov tsawg, feem ntau 17-18.5 feem pua, tab sis tus nqi pheej yig dua li ntawm cov cell monocrystalline silicon. Kev hloov dua siab tshiab ntawm amorphous silicon cells yog qhov qis tshaj plaws, feem ntau 6-8 feem pua, thiab cov nqi tsim khoom kuj tsawg heev.
2. Qhov ntev ntawm lub hnub ci vaj huam sib luag
Muaj ntau qhov ntau thiab tsawg ntawm cov hnub ci vaj huam sib luag. Rau tib lub zog, nws yog qhov tsim nyog xaiv qhov me me. Lub zog ntawm lub hnub ci vaj huam sib luag yog proportional rau thaj tsam ntawm lub hnub ci wafer. Lub cheeb tsam ntawm lub hnub ci cell wafer tsis yog tag nrho sib npaug rau thaj tsam ntawm lub hnub ci ntim vaj huam sib luag. Vim tias qee lub hnub ci vaj huam sib luag loj, qhov sib txawv ntawm ib lub hnub ci wafers dav heev, thiab lub zog ntawm cov hnub ci vaj huam sib luag tsis tas yuav siab.
3. Durability
Complex sab nraum zoov ib puag ncig thiab huab cua hnyav xws li lawg, nag thiab daus yuav tsum tau txiav txim siab thaum tsim lub hnub ci txoj kev teeb pom kev zoo. Yog tias cov hnub ci vaj huam sib luag xav kom lav lub neej ntev tshaj 25 xyoo, lawv yuav tsum siv cov khoom zoo thiab cov khoom zoo. Tab sis tsis yog txhua lub hnub ci hluav taws xob txoj kev teeb pom kev lag luam yuav siv cov hnub ci zoo. Thaum yuav cov hnub ci vaj huam sib luag, peb yuav tsum ua tib zoo xyuas qee qhov chaw.
Txheeb xyuas qhov chaw ntawm lub iav tempered, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws Thawj theem yuav tsis pom tseeb. Tab sis tej yam tsis meej yuav cuam tshuam rau kev ua haujlwm ib txwm ua haujlwm ntawm lub roj teeb vaj huam sib luag.
Xyuas cov roj teeb. Thaum nws yog spliced, siv tawg splicing. Txoj kev no yuav ua rau lub rooj zaum zaj yuav raug txiav thaum siv, uas yuav cuam tshuam rau kev ua haujlwm tag nrho.
Kos rau sab nraub qaum kom pom tias muaj npuas thiab lwm yam tshwm sim nyob tom qab.
Xyuas seb cov silica gel ntawm plaub sab zoo li cas thiab nkag mus.
Txheeb xyuas tus ncej kom pom tias lub zog ntawm tus ncej yog txawm thiab qhov nruj sib txawv.
Txheeb xyuas qhov vuam kom pom tias muaj qhov ploj lawm. Saib seb lub roj teeb tsis tu ncua.
Saib yog tias lub thawv sib txuas yog nruj, xaiv thiab hloov pauv dawb.
4. Xaiv qhov voltage thiab lub zog ntawm lub hnub ci vaj huam sib luag
Lub zog ua haujlwm ntawm lub hnub ci cell yog kwv yees li 1.5 npaug ntawm lub roj teeb hluav taws xob kom ntseeg tau tias lub roj teeb li qub tau them. Piv txwv li, 8 ~ 9V hnub ci hlwb yuav tsum tau them 6v cia roj teeb, thiab 15 ~ 18V hnub ci hlwb yuav tsum tau them 12V cia roj teeb. 33-36V lub hnub ci yuav tsum tau them rau 24V roj teeb.
Txhawm rau txhawb kev teeb pom kev zoo ntawm lub hnub ci hluav taws xob txoj kev teeb pom kev zoo yam tsis tau them nyiaj rau hnub huab cua thiab nag los nag, lub zog them txhua hnub ntawm lub hnub ci vaj huam sib luag yuav tsum muaj ntau dua li lub zog tso tawm txhua hnub. Lub zog ntau dhau yog khaws cia rau hauv lub roj teeb thiab tuaj yeem siv rau hnub huab cua thiab nag. Lub zog tsim los ntawm lub hnub ci vaj huam sib luag=lub zog ntawm lub hnub ci vaj huam sib luag muab faib los ntawm qhov hluav taws xob ntawm lub hnub ci vaj huam sib luag. Xav tias lub zog ntawm lub hnub ci vaj huam sib luag yog 25W thiab qhov hluav taws xob yog 18V. Lub sijhawm teeb pom kev zoo yog 5 teev, yog li lub zog tsim hluav taws xob ntawm lub hnub ci vaj huam sib luag yog sib npaug rau 100W / 18V=1.3A * 5h=6.9Ah. Lub peev xwm tawm ntawm lub hnub ci vaj huam sib luag yog sib npaug ntawm lub zog ntawm LED teeb qhov chaw muab faib los ntawm lub hnub ci hauv zos. Xav tias lub wattage ntawm lub teeb yog 20W, qhov voltage yog 12.8V, thiab lub hnub ci lub sij hawm yog 5 teev. Lub peev xwm tawm ntawm lub hnub ci vaj huam sib luag hauv ib hnub yog 10W * 5h=50Wh. Tom qab ntawd siv 50Wh/12.8V=3.9Ah. Nws yog qhov tsim nyog tias lub zog tsim hluav taws xob muaj peev xwm ntawm lub hnub ci vaj huam sib luag yog ntau dua qhov muaj peev xwm tawm.
