Kungani kudingeka abalawuli bokushaja ohlelweni lokukhanya kwelanga?
Abalawuli balawula ukushaja kwamabhethri futhi uma kungekho mandla akhiqizwayo, bavula i-LED. Ebusuku lapho ugesi ungasakhiqizwa, kungenzeka ukuthi ugesi ogciniwe ugeleze ubuyele emuva usuka ebhethri uye kumaphaneli elanga. Lokhu kungakhipha amabhethri futhi isilawuli sokushaja selanga singavimbela lokhu kugeleza kwamandla okubuyela emuva. Abalawuli be-solar charge banqamula amaphaneli elanga kumabhethri uma bebona ukuthi akukho ukukhiqizwa kwamandla ngamaphaneli futhi ngaleyo ndlela bagweme ukushaja ngokweqile.
Ukushaja ngokweqile kungabangela kakhulu ukuncipha kokuphila kwebhethri futhi ngezinye izikhathi umonakalo omkhulu kumabhethri. Izilawuli zokushaja zelanga zanamuhla ziyasiza ekwandiseni impilo yebhethri ngokunciphisa inani lamandla asetshenziswa kumabhethri lapho amabhethri esecishe ashajwe ngokugcwele futhi aguqula i-voltage eyengeziwe ibe yi-amperage.
Izilawuli zokushaja zelanga ziyadingeka ngoba:
● Zinikeza inkomba ecacile uma ibhethri lishajwa
● Zivimba ibhethri ukuthi lingashaji kakhulu futhi lingashaji kakhulu
● Zilawula i-voltage yebhethri
● Zivimba ukugeleza kwamanzi emuva
Izinhlobo zezilawuli zokushaja zelanga
Izilawuli zokushaja ze-Pulse Width Modulation (PWM):
Laba balawuli basebenzisa indlela elawula ukugeleza kwamandla kagesi ebhethrini ngokunciphisa amandla kagesi kancane kancane okwaziwa ngokuthi i-pulse width modulation. Uma ibhethri seligcwele futhi lifinyelela esigabeni sokushaja esilinganiselayo, isilawuli siyaqhubeka nokunikeza amandla amancane ukuze sigcine ibhethri ligcwele. Amabhethri amaningi ashajwayo avame ukuzikhipha futhi alahlekelwe amandla ngisho nangemva kokushajwa ngokugcwele. Isilawuli se-PWM sigcina ishaja ngokuqhubeka nokunikeza amandla kagesi amancane afanayo nawesilinganiso sokuzikhipha.
Izinzuzo
●Akubizi kakhulu
●Ubuchwepheshe obudala nobesebuhlolwe isikhathi eside
●Ihlala isikhathi eside futhi isebenza kahle emazingeni okushisa afudumele
● Itholakala ngezinhlelo zokusebenza ezahlukahlukene ngobukhulu obuhlukahlukene
● Ukusebenza kahle okungu-65% kuya ku-75% kuphela
●I-voltage yokufaka ilanga kanye ne-voltage evamile yebhethri kufanele ifane
●Ayihambelani namamojula wokuxhuma igridi enamandla aphezulu
Ukungalungi
Izilawuli zokushaja ze-Maximum power point tracking (MPPT):
Laba balawuli basebenzisa indlela yokwenza iphaneli yelanga isebenze endaweni yayo ephezulu yamandla. Iphaneli yelanga ithola amazinga ahlukahlukene okukhanya kwelanga phakathi nosuku futhi lokhu kungabangela ukuthi i-voltage yephaneli kanye nogesi kushintshe njalo. I-MPPT isiza ukulandelela nokulungisa i-voltage ukuze ikhiqize amandla aphezulu kungakhathaliseki ukuthi isimo sezulu sinjani.
Izinzuzo
●Shaja ngokushesha futhi isikhathi eside sokuphila
●Isebenza kahle kakhulu kune-PWM
●Ubuchwepheshe bamuva
●Izinga lokuguqulwa lingafinyelela ku-99%
●Isebenza kangcono ezindaweni ezibandayo
●Kubiza kakhulu
●Inkulu ngosayizi uma iqhathaniswa ne-PWM

Ungakhetha kanjani isilawuli sokushaja esifanele?
Ngokusekelwe kumthamo wamanje, kufanele kukhethwe isilawuli sokushaja selanga esihambisana ne-voltage yesistimu. Izilawuli ze-MPPT zivame ukusetshenziswa ezibanini zasemgwaqweni zelanga. Izilawuli zokushaja zelanga zibhekwa njengedivayisi yokuvikela futhi zikhipha okungcono kakhulu kulokho onakho.isibani somgwaqo selangaIzici okufanele uzikhumbule lapho ukhetha isilawuli esifanele yilezi:
●Isikhathi sokuphila sesilawuli
●Izimo zokushisa lapho kuzofakwa khona uhlelo lwelanga
● Izidingo zakho zamandla
●Inani lamaphaneli elanga kanye nokusebenza kwawo kahle
●Usayizi wohlelo lwakho lokukhanya kwelanga
●Uhlobo lwamabhethri asetshenziswa ohlelweni lokukhanya kwelanga
Imininingwane yobuchwepheshe efana nezingxenye ezisetshenzisiwe, ukusebenza kahle kwazo kanye nesikhathi sokuphila kwazo kunikezwa ngokuningiliziwe ngohlelo ngalunye lokukhanya kwelanga. Ngokusekelwe kwisabelomali sakho, izici ozidingayo kanye nendawo yokufakwa, ungakhetha isilawuli esifanele izibani zakho zelanga.
Njengoba kuboniswe esithombeni, i-Zenith Lighting ingumkhiqizi ochwepheshe wazo zonke izinhlobo zezibani zelanga neminye imikhiqizo ehlobene nayo, uma unemibuzo noma iphrojekthi, sicela ungangabazi ukuyiphendula. xhumana nathi.
