5 Yam Koj Yuav Tsum Paub Txog Hnub Ci Dej Nyab Teeb thiab Txoj Kev Teeb
Aug 31, 2023| Covhnub ci dej nyab teebthiabtxoj kev teebxa mus rau cov teeb pom kev zoo uas siv lub hnub ci zog los tsim hluav taws xob rau kev teeb pom kev zoo. Cov tshuab no feem ntau muaj xws li hnub ci vaj huam sib luag, roj teeb, thiab LED teeb, nrog rau tus nqi tswj. Lub teeb hnub ci yog feem ntau siv rau ntau yam kev siv, xws li teeb pom kev zoo, teeb pom kev hauv vaj, thiab teeb pom kev zoo sab nraum zoov.
Nov yog 5 yam koj yuav tsum paub txog hnub ci teeb:
1, Hnub ci teeb hom:
 |
 |
Muaj 2 hom hnub ci dej nyab teeb, tag nrho-hauv-ib thiab cais hom. All-in-ib hom hnub ci dej nyab teeb tseem hu ua "Integrated solar floodlights", uas yog ib qho kev sib txuas ntawm lub hnub ci vaj huam sib luag, lithium roj teeb, LED qhov chaw teeb pom kev zoo thiab cov khoom siv ntse, PIR lossis Motion sensor, thiab lwm yam. Yooj yim rau kev thauj mus los thiab sib dhos kom kawg. cov neeg siv; Split-hom hnub ci dej nyab lub teeb muab faib ua tiav cais thiab tag nrho-hauv-ob hom. Ua tiav kev sib cais txhais tau hais tias txhua qhov sib cais, hom no feem ntau siv cov roj teeb txhuas-acid uas muaj qhov loj me. Tag nrho nyob rau hauv ob hom txhais tau hais tias Lithium roj teeb thiab tswj yog tsim-hauv LED dej nyab teeb lub cev, lub hnub ci vaj huam sib luag yog cais.
2, Hnub ci vaj huam sib luag:
Hnub ci vaj huam sib luag tau muab faib ua Monocrystalline thiab Polycrystalline.

Plaub lub ces kaum ntawm Monocrystalline vaj huam sib luag qhia ib ncig arc, thiab tsis muaj cov qauv ntawm qhov chaw, lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci panels yog nyob nruab nrab ntawm 17 thiab 24 feem pua, nrog rau qhov nruab nrab ntawm 18 feem pua. Lub hnub ci cell no muaj qhov zoo tshaj plaws photoelectric hloov dua siab tshiab ntawm txhua yam thiab lub neej ntev txog li 25 xyoo. Txawm li cas los xij, cov nqi tsim khoom yog ntau dua Polycrystalline.
Plaub lub kaum sab xis ntawm lub vaj huam sib luag polycrystalline qhia lub kaum sab xis, thiab qhov chaw muaj tus qauv. Txoj kev tsim khoom ntawm polycrystalline silicon hnub ci vaj huam sib luag yog tib yam li monocrystalline silicon hnub ci vaj huam sib luag, txawm li cas los xij lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci panels yog qis dua monocrystalline silicon solar panels, nws yog nyob ib ncig ntawm 16%. Tab sis nws yog pheej yig dua li monocrystalline silicon solar panels. Qhov chaw ntawm lub rooj tsavxwm polycrystalline nrog tib lub zog yog me ntsis loj dua li ntawm lub rooj tsavxwm monocrystalline. Piv txwv li, 50W polycrystalline board yuav yog 1.1 npaug loj dua li ntawm lub rooj tsavxwm monocrystalline. Lub phaj polycrystalline tau txais lub teeb nyob rau hauv ntau cov lus qhia thiab muaj kev taw qhia zoo. Hauv qhov kev sim tiag tiag, yog tias ib txhais tes siv los thaiv lub hnub ci lub teeb kom tawm hauv qhov ntxoov ntxoo ntawm lub hnub ci vaj huam sib luag, ces tam sim no txo qis ntawm polycrystalline hnub ci vaj huam sib luag tsis pom tseeb, tab sis monocrystalline hnub ci vaj huam sib luag yog pom tseeb, uas yog qhov zoo dua. ntawm polycrystalline phaj. Thiab nws tus nqi kuj tsawg.
3, Roj teeb:
Muaj 2 hom roj teeb uas siv rau hnub ci dej nyab teeb, Lead-acid Battery thiab Lithium Battery.

Valve tswj cov roj teeb txhuas-acid muaj xws li nqus cov iav lev lead-acid roj teeb (AGM) thiab cov roj teeb colloidal lead-acid (Gel). Lawv feem ntau yog siv nyob rau hauv split-type solar street light systems thiab feem ntau yog faus rau hauv av. Lawv loj dua thiab pheej yig dua, tab sis lawv siv tsawg dua li cov roj teeb lithium-ion. Feem ntau cov roj ntsha lead-acid yog 12V lossis 24V systems. Tsis tas li ntawd, cov roj teeb lead-acid muaj txog 75% tawm qhov tob, thiab yuav tsum tau them thaum cov paug tawm li 25% sab laug. Yog li, kom tsis txhob tso tawm 100% yog qhov tseem ceeb heev hauv kev siv.
Feem ntau ntawm lithium roj teeb siv nyob rau hauv lub hnub ci txoj kev teeb pom kev zoo yog ternary lithium roj teeb thiab lithium hlau phosphate roj teeb (LiFePo4). Cov roj teeb lithium yog tus nqi ntau dua thiab muaj lub neej ntev dua li cov roj ntsha lead-acid. Ternary lithium roj teeb muab kev tiv thaiv txias zoo dua piv rau lithium hlau phosphate roj teeb. Lub siab kub tsis kam ntawm lithium hlau phosphate roj teeb yog zoo dua li ntawm ternary lithium roj teeb. Yog li ntawd, hnub ci dej nyab lub teeb nyob rau hauv cov cheeb tsam kub siab feem ntau siv lithium hlau phosphate roj teeb. Thiab ternary lithium roj teeb yog pheej yig dua li 25% lithium hlau phosphate roj teeb. Muaj Lithium roj teeb voltages rau lub hnub ci txoj kev teeb muaj xws li 3.2V, 6.4V, 12.8V, thiab 25.6V.
4, Controllers:
PWM (Pulse Width Modulation) thiab MPPT (Maximum Power Point Tracking) yog ob hom kev them nyiaj hnub ci uas siv rau hauv lub hnub ci fais fab. Lawv yog lub luag haujlwm rau kev tswj hwm qhov voltage thiab tam sim no los ntawm lub hnub ci vaj huam sib luag mus rau cov roj teeb, kom ntseeg tau tias cov roj teeb muaj txiaj ntsig zoo thiab lawv lub neej muaj kev tiv thaiv.

Qhov sib txawv tseem ceeb ntawm PWM thiab MPPT controllers yog:
1). Kev ua tau zoo. MPPT controllers muaj txiaj ntsig zoo dua li PWM controllers.MPPT controllers tuaj yeem rho tawm mus txog 98% ntawm cov hluav taws xob muaj los ntawm hnub ci vaj huam sib luag, thaum PWM controllers raug txwv rau thaj tsam 80% kev ua haujlwm. Qhov no ua rau MPPT controllers yog ib qho kev xaiv zoo dua rau lub hnub ci loj dua lossis cov tshuab uas muaj qhov chaw txwv rau hnub ci vaj huam sib luag.
2). Tus nqi: PWM controllers feem ntau tsis tshua kim tshaj MPPT maub los vim lawv cov cuab yeej siv yooj yim. Txawm li cas los xij, qhov ua tau zoo dua ntawm MPPT cov tswj hwm tuaj yeem ua rau lawv muaj txiaj ntsig zoo dua nyob rau lub sijhawm ntev, tshwj xeeb tshaj yog rau lub hnub ci loj.
3). Functionality: MPPT controllers muaj cov cuab yeej siv siab tshaj plaws uas tso cai rau lawv taug qab lub zog siab tshaj plaws ntawm lub hnub ci vaj huam sib luag, uas hloov pauv nrog lub hnub ci thiab qhov kub thiab txias. Qhov no ua rau MPPT controllers optimize lub zog tso zis thiab txhim kho tag nrho cov efficiency ntawm lub hnub ci system. PWM controllers, ntawm qhov tod tes, tsuas yog tswj qhov voltage thiab tam sim no rau cov roj teeb yam tsis tau taug qab qhov siab tshaj plaws lub zog taw tes.
4). Flexibility: MPPT controllers tuaj yeem ua ntau yam ntawm lub hnub ci vaj huam sib luag teeb tsa thiab qhov hluav taws xob, ua rau lawv muaj ntau yam rau kev teeb tsa lub hnub ci sib txawv. PWM controllers muaj ntau qhov kev txwv nyob rau hauv cov nqe lus ntawm lub hnub ci vaj huam sib luag voltage thiab configuration lawv muaj peev xwm lis.
Hauv cov ntsiab lus, PWM controllers yog ib qho kev xaiv pheej yig dua thiab yooj yim, haum rau lub hnub ci me me, thaum MPPT controllers muaj kev ua tau zoo dua thiab yooj yim dua, ua rau lawv xaiv zoo dua rau lub hnub ci loj lossis ntau dua.
5, LED teeb qhov chaw:
Kev xaiv cov teeb pom kev zoo rau hnub ci teeb pom kev zoo tuaj yeem yog qhov kev txiav txim siab tseem ceeb uas tuaj yeem cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev ua haujlwm ntawm lub teeb pom kev zoo. Nov yog ob peb yam uas yuav tsum tau xav txog thaum xaiv lub teeb ci rau hnub ci teeb pom kev zoo:
1). Brightness: Qhov ci ci ntawm lub teeb ci yog qhov tseem ceeb rau kev txiav txim siab. Koj yuav xav xaiv lub teeb ci uas ci txaus zoo li 170lm -210lm / w kom muaj teeb pom kev txaus, tab sis tsis ci ntsa iab uas nws siv zog ntau dhau thiab tso lub roj teeb sai.
2). Kev siv hluav taws xob: Hnub ci teeb pom kev zoo tso siab rau lub zog los ntawm lub hnub los ua lub zog rau lub teeb, yog li nws yog ib qho tseem ceeb uas yuav tsum xaiv cov teeb pom kev zoo uas siv hluav taws xob thiab tsis tas yuav siv hluav taws xob ntau dhau. LED teeb yog ib qho kev xaiv zoo rau lub hnub ci teeb pom kev zoo vim tias lawv muaj txiaj ntsig zoo thiab siv lub zog tsawg dua li lwm hom teeb pom kev zoo.
3). Lifespan: Lub neej ntev ntawm lub teeb ci tseem ceeb heev. Koj yuav xav xaiv lub teeb pom kev zoo uas ruaj khov thiab kav ntev, yog li koj tsis tas yuav hloov nws ntau zaus.
4). Xim kub: Cov xim kub ntawm lub teeb pom kev tuaj yeem cuam tshuam rau tag nrho cov saib thiab kev xav ntawm lub teeb pom kev zoo. Koj yuav xav xaiv cov xim kub uas tsim nyog rau ib puag ncig thiab kev npaj siv lub teeb pom kev zoo.
Zuag qhia tag nrho, xaiv qhov chaw teeb pom kev zoo rau lub hnub ci teeb pom kev zoo yuav tsum tau ua tib zoo xav txog ntau yam, suav nrog kev ci ntsa iab, lub zog ua haujlwm, lub neej ntev, thiab xim kub. Nws yuav yog ib lub tswv yim zoo los tham nrog tus kws tshaj lij lossis tus neeg muag khoom los txiav txim siab qhov zoo tshaj plaws lub teeb rau koj cov kev xav tau tshwj xeeb.
