Ukutshala imali ohlelweni lwelanga kuyisixazululo esihlakaniphile sabanikazi bezindlu ngokuhamba kwesikhathi, ikakhulukazi ngaphansi kwezimo zamanje lapho inkinga yamandla eyenzeka ezindaweni eziningi.Iphaneli yelanga ingasebenza iminyaka engaphezu kwengama-30, futhi namabhethri e-lithium athola isikhathi eside sokuphila njengoba ubuchwepheshe buthuthuka.

Ngezansi kunezinyathelo eziyisisekelo okudingeka udlule kuzo ukuze ufinyelele usayizi wesistimu yelanga ekahle yekhaya lakho.

Isinyathelo 1: Thola inani eliphelele lamandla asetshenziswa endlini yakho

Udinga ukwazi amandla aphelele asetshenziswa izinto zakho zikagesi zasendlini.Lokhu kukalwa ngeyunithi ye-kilowatt/ihora nsuku zonke noma nyanga zonke.Ake sithi, isisetshenziswa esiphelele endlini yakho sisebenzisa amandla angama-watt ayi-1000 futhi sisebenza amahora ayi-10 ngosuku:

1000w * 10h = 10kwh ngosuku.

Amandla alinganiselwe ento ngayinye yasendlini angatholakala kumanuwali noma kumawebhusayithi abo.Ukuze ube neqiniso, ungase ucele abasebenzi bezobuchwepheshe ukuthi bazilinganise ngamathuluzi afanele afanele njengemitha.

Kungaba khona ukulahleka kwamandla kusuka ku-inverter yakho, noma isistimu ikumodi yokuma.Engeza u-5% - 10% ukusetshenziswa kwamandla ngokwesabelomali sakho.Lokhu kuzocatshangelwa uma usayizi amabhethri akho.Kubalulekile ukuthenga i-inverter yekhwalithi.(Thola okwengeziwe mayelana nama-inverters ethu ahlolwe ngokuqinile)

Isinyathelo sesi-2: Ukuhlolwa Kwesayithi

Manje udinga ukuba nombono ojwayelekile mayelana nokuthi angakanani amandla elanga ongawathola nsuku zonke ngokwesilinganiso, ukuze wazi ukuthi mangaki amaphaneli elanga ozodinga ukuwafaka ukuze uhlangabezane nesidingo sakho sansuku zonke samandla.

Ulwazi lwamandla elanga lungaqoqwa kumephu Yehora Lelanga lezwe lakini.Imithombo yemephu yemisebe yelanga ingatholakala kokuthi https://globalsolaratlas.info/map?c=-10.660608,-4.042969,2

Manje, Ake sithatheeDamaseku iSiriyanjengesibonelo.

Masisebenzise isilinganiso samahora angu-4 elanga njengesibonelo sethu njengoba sifunda kumephu.

Amaphaneli elanga aklanyelwe ukufakwa elangeni eligcwele.Umthunzi uzoba nomthelela ekusebenzeni.Ngisho nomthunzi oyingxenye kuphaneli eyodwa uzoba nomthelela omkhulu.Hlola isayithi ukuze uqiniseke ukuthi i-solar array yakho izochayeka elangeni eligcwele phakathi namahora welanga ashisa kakhulu nsuku zonke.Khumbula ukuthi i-engeli yelanga izoshintsha unyaka wonke.

Kukhona ezinye izinto ezimbalwa okufanele uzikhumbule.Singakhuluma ngabo kuyo yonke inqubo.

Isinyathelo sesi-3: Bala Usayizi Webhange Lebhethri

Njengamanje sesinolwazi oluyisisekelo losayizi webhethri.Ngemuva kokuthi ibhange lebhethri lilinganisiwe, singanquma ukuthi mangaki amaphaneli elanga adingekayo ukuze ihlale ishajiwe.

Okokuqala, sibheka ukusebenza kahle kwama-solar inverters.Ngokuvamile ama-inverter afika nesilawuli sokushaja esakhelwe ngaphakathi se-MPPT esisebenza kahle ngaphezu kuka-98%.(Bheka ama-inverters ethu elanga).

Kodwa kusenengqondo ukucabangela isinxephezelo sokungasebenzi kahle esingu-5% uma senza usayizi.

Esibonelweni sethu se-10KWh/ngosuku ngokusekelwe kumabhethri e-lithium,

10 KWh x 1.05 isinxephezelo esisebenzayo = 10.5 KWh

Leli inani lamandla adonswa ebhethrini ukuze kuhanjiswe umthwalo ku-inverter.

Njengoba izinga lokushisa elihle lokusebenza lebhethri ye-lithium liyi-bwtween 0℃eya 0-40℃, nakuba izinga lokushisa layo lokusebenza liku--20℃~60℃.

Amabhethri alahlekelwa amandla njengoba amazinga okushisa ehla futhi singasebenzisa ishadi elilandelayo ukukhulisa umthamo webhethri, ngokusekelwe kuzinga lokushisa elilindelekile lebhethri:

Isibonelo sethu, sizongeza isiphindaphindi esingu-1.59 kusayizi webhange lethu ukuze sinxephezele izinga lokushisa lebhethri elingu-20°F ebusika:

10.5KWhx 1.59 = 16.7KWh

Okunye okucatshangelwayo ukuthi lapho ushaja futhi ukhipha amabhethri, kukhona ukulahlekelwa kwamandla, futhi ukwandisa ubude besikhathi sokuphila kwamabhethri, akukhuthazwa ukuba akhiphe ngokugcwele amabhethri.(Ngokuvamile sigcina i-DOD iphakeme kune-80% (DOD = ukujula kokukhishwa).

Ngakho sithola ubuncane bomthamo wokugcina amandla: 16.7KWh * 1.2 = 20KWh

Lokhu okosuku olulodwa lokuzimela, ngakho-ke sidinga ukuphinda sikuphindaphinde ngenani lezinsuku zokuzimela okudingekayo.Ezinsukwini ezi-2 zokuzimela, kungaba:

20Kwh x 2 izinsuku = 40KWh yokugcina amandla

Ukuze uguqule amahora we-watt abe ama-amp amahora, hlukanisa nge-voltage yebhethri yesistimu.Esibonelweni sethu:

40Kwh ÷ 24v = 1667Ah 24V ibhange lebhethri

40Kwh ÷ 48v = 833 Ah 48V ibhange lebhethri

Uma ulinganisa ibhange lebhethri, hlala ucabangela ukujula kokukhipha, noma ukuthi umthamo ongakanani okhishwa ebhethrini.Ukulinganisa ibhethri le-asidi yomthofu ukujula okungu-50% kokuphuma kuzonweba impilo yebhethri.Amabhethri e-lithium awathinteki njengokuchithwa okujulile, futhi angakwazi ukuphatha ukukhishwa okujulile ngaphandle kokuthinta kakhulu impilo yebhethri.

Isamba esidingekayo ubuncane bomthamo webhethri: 2.52 kilowatt amahora

Qaphela ukuthi leli inani elincane lomthamo webhethri elidingekayo, futhi ukukhulisa usayizi webhethri kungenza isistimu ithembeke kakhulu, ikakhulukazi ezindaweni ezijwayele ukuguquguquka okunwetshiwe.

Isinyathelo sesi-4: Thola ukuthi Mangaki Amaphaneli elanga owadingayo

Manje njengoba sesinqume umthamo webhethri, singakwazi usayizi wesistimu yokushaja.Ngokuvamile sisebenzisa amaphaneli elanga, kodwa inhlanganisela yomoya nelanga ingase ibe nengqondo ezindaweni ezinomthombo omuhle womoya, noma kumasistimu adinga ukuzimela okwengeziwe.Isistimu yokushaja idinga ukukhiqiza okwanele ukuze ibuyisele ngokugcwele amandla akhishwe ebhethrini kuyilapho ibala konke ukulahlekelwa kokusebenza kahle.

Esibonelweni sethu, ngokusekelwe emahoreni angu-4 elanga kanye nama-40 Wh ngesidingo samandla sosuku:

40KWh / 4 amahora = 10 Kilo Watts Solar Panel Array Usayizi

Kodwa-ke, sidinga okunye ukulahlekelwa emhlabeni wethu wangempela okubangelwa ukungasebenzi kahle, njengokwehla kwamandla kagesi, okuvame ukulinganiselwa cishe ku-10%:

10Kw÷0.9 = 11.1 KW ubuncane bosayizi we-PV yamalungu afanayo

Qaphela ukuthi lobu ubuncane bukasayizi we-PV yamalungu afanayo.Uhlu olukhulu luzokwenza uhlelo luthembeke kakhulu, ikakhulukazi uma ungekho omunye umthombo wamandla oyisipele wamandla, njengejeneretha, otholakalayo.

Lezi zibalo ziphinde zicabange ukuthi i-solar array izothola ukukhanya kwelanga okuqondile okungavinjelwe kusuka ngo-8 AM kuya ku-4 PM phakathi nazo zonke izinkathi zonyaka.Uma konke noma ingxenye ye-solar i-shaded phakathi nosuku, ukulungiswa kusayizi we-PV we-array udinga ukwenziwa.

Okunye ukucatshangelwa okufanele kubhekwe: amabhethri e-lead-acid adinga ukushajwa ngokugcwele njalo.Adinga ubuncane obungama-amps ayi-10 wokushaja wamanje ngamahora angu-100 amp womthamo webhethri ukuze uthole impilo yebhethri ephelele.Uma amabhethri e-lead-acid engashajwa kabusha njalo, azohluleka, ngokuvamile phakathi nonyaka wokuqala esebenza.

Isilinganiso esiphezulu sokushajwa kwamabhethri e-asidi yomthofu ngokuvamile singama-amps angu-20 ngo-100 Ah (izinga lokushaja le-C/5, noma umthamo webhethri emahoreni angama-amp ahlukaniswe ngo-5) futhi ndawana thize phakathi kwalolu hlu ilungile (ama-amps angu-10-20 wokushaja okwamanje ngo-100ah ngamunye. ).

Bheka imininingwane yebhethri kanye nemanuwali yomsebenzisi ukuze uqinisekise ubuncane nemihlahlandlela yokushaja okuphezulu.Ukwehluleka ukuhlangabezana nale mihlahlandlela ngokuvamile kuzovala iwaranti yebhethri lakho futhi kubeke engcupheni yokwehluleka kwebhethri ngaphambi kwesikhathi.

Ngalo lonke lolu lwazi, uzothola uhlu lokucushwa okulandelayo.

Iphaneli yelanga: Watt11.1KW20 pcs of 550w solar panel

25 pcs 450w amaphaneli elanga

Ibhethri 40KWh

1700AH @ 24V

900AH @ 48V

Ngokuqondene ne-inverter, ikhethwa ngokusekelwe emandleni aphelele wemithwalo oyodinga ukuyiqhuba.Kulokhu, umshini wasendlini we-1000w, i-inverter ye-solar engu-1.5kw izokwanela, kodwa empilweni yangempela, abantu badinga ukusebenzisa imithwalo eminingi ngesikhathi esifanayo ngezikhathi ezahlukene nsuku zonke, kunconywa ukuthenga i-solar engu-3.5kw noma i-5.5kw. ama-inverters.

Lolu lwazi luhloselwe ukusebenza njengomhlahlandlela ojwayelekile futhi kunezici eziningi ezingaba nomthelela kusayizi wesistimu.

Uma imishini ibalulekile futhi isendaweni ekude, kufanelekile ukutshala ohlelweni olukhulu kakhulu ngoba izindleko zokulungiswa zingadlula ngokushesha intengo yamaphaneli elanga noma amabhethri engeziwe ambalwa.Ngakolunye uhlangothi, kwezinye izinhlelo zokusebenza, ungase ukwazi ukuqala kancane futhi wandise kamuva kuye ngokuthi isebenza kanjani.Usayizi wesistimu ekugcineni uzonqunywa ukusetshenziswa kwakho kwamandla, indawo yesayithi kanye nokulindelwe kokusebenza okusekelwe ezinsukwini zokuzimela.

Uma udinga usizo ngale nqubo, zizwe ukhululekile ukuxhumana nathi futhi singakha isistimu yezidingo zakho ngokusekelwe endaweni kanye nezidingo zamandla.
