I-MPPT vs. PWM: Isiphi isilawuli esilungele ukukhanya okukhanyayo okuphuzi kwelanga?

Emkhakheni wezixazululo zelanga,izibani ezikhanyayo zelanga eziphuzisebeyingxenye ebalulekile yezinhlelo zokusebenza ezahlukahlukene ezihlanganisa ukuphathwa kwethrafikhi, izindawo zokwakha, nezimpawu eziphuthumayo. Njengomhlinzeki onesipiliyoni wamalambu akhanyayo aphuzi aphuzi, u-Qixiang uyakuqonda ukubaluleka kokukhetha isilawuli esifanele sokuthuthukisa ukusebenza kwalezi zibani. Kunezinhlobo ezimbili eziyinhloko zezilawuli zeshaja yelanga ezivame ukusetshenziswa ezinhlelweni zelanga: I-Maximum Power Point Tracking (MPPT) kanye ne-Pulse Width Modulation (PWM). Lesi sihloko sizongena phakathi komehluko phakathi kwezilawuli ze-MPPT ne-PWM futhi sikusize unqume ukuthi yisiphi isilawuli esilungele izidingo zakho zokukhanya okukhanyayo okuphuzi kwelanga.

Funda mayelana nezilawuli zokushaja zelanga

Ngaphambi kokungena esiqhathanisweni, kubalulekile ukuqonda ukuthi isilawuli se-solar charge senzani. Lawa madivaysi alawula i-voltage kanye namanje kusuka kumaphaneli elanga kuya ebhethrini, iqinisekisa ukuthi ibhethri ishajwe kahle futhi ngokuphepha. Ukukhethwa kwesilawuli kungathinta kakhulu ukusebenza nokuphila isikhathi eside kwesistimu yakho yokukhanya okukhanyayo okuphuzi okunozungezilanga.

Abalawuli be-PWM

Izilawuli ze-Pulse width modulation (PWM) ziwuhlobo lwendabuko lwesilawuli sokushaja solar. Basebenza ngokuxhuma iphaneli yelanga ngqo ebhethri futhi basebenzise uchungechunge lwezimpawu zokushintsha ukulawula inqubo yokushaja. Ububanzi besignali "yokuvula" bulungiswa ngokusekelwe esimweni sokushajwa kwebhethri, okuvumela inqubo yokushaja ezinzile nelawulekayo.

Izinzuzo zezilawuli ze-PWM:

1. Ilula futhi Ibiza kakhulu:

Izilawuli ze-PWM ngokuvamile zishibhile futhi kulula ukuzifaka kunezilawuli ze-MPPT. Lokhu kubenza babe ukukhetha okukhangayo kumaphrojekthi akhathalela ibhajethi.

2. Ukwethembeka:

Ngenxa yezingxenye ezimbalwa nemiklamo elula, izilawuli ze-PWM zivame ukwethembeka kakhulu futhi zidinga ukulungiswa okuncane.

3. Ukusebenza kahle Ezinhlelweni Ezincane:

Ezinhlelweni ezincane sonozungezilanga lapho i-voltage yephaneli yelanga ihambisana eduze ne-voltage yebhethri, ukusebenza kahle kwesilawuli se-PWM kuphezulu kakhulu.

Abalawuli beMPPT

Izilawuli ze-Maximum Power Point Tracking (MPPT) ziwubuchwepheshe obuthuthuke kakhulu obuthuthukisa amandla aqoqwe kumaphaneli elanga. Bahlala beqapha ukukhishwa kwamapaneli elanga futhi balungise indawo yokusebenza kagesi ukuze baqinisekise ukuthi amandla amaningi akhishwa.

Izinzuzo zesilawuli se-MPPT:

1. Ukusebenza Okuphezulu:

Uma kuqhathaniswa nabalawuli be-PWM, abalawuli be-MPPT bangakhuphula ukusebenza kahle kwezinhlelo zelanga kuze kufike ku-30%, ikakhulukazi uma i-voltage yephaneli yelanga iphakeme kune-voltage yebhethri.

2. Ukusebenza okungcono ezimeni zokukhanya okuphansi:

Isilawuli se-MPPT senza kahle ezimeni eziphansi zokukhanya, okusenza silungele ukukhanya okuphuzi kwelanga okudinga ukusebenza kahle ngisho nangezinsuku eziguqubele noma lapho kuhwalala.

3. Ukuguquguquka komklamo wesistimu:

Izilawuli ze-MPPT zivumela ukuguquguquka okukhulu ekwakhiweni kwesistimu ukusebenzisa amaphaneli elanga aphezulu kagesi, okunganciphisa izindleko zezintambo nokulahlekelwa.

Isiphi isilawuli esingcono kakhulu sokukhanya okuphuzi kokukhanya kwelanga?

Uma ukhetha i-MPPT kanye nezilawuli ze-PWM zokukhanyisa ukukhanya okuphuzi kwelanga, isinqumo sincike kakhulu ezidingweni ezithile zohlelo lwakho lokusebenza.

- Emaphrojekthini Amancane, Avimbelwe Kubhajethi: Uma usebenza kuphrojekthi encane enesabelomali esilinganiselwe, isilawuli se-PWM singanele. Zithembekile, zingabizi kakhulu, futhi zinganikeza amandla anele ezibani ezikhanyayo zelanga eziphuzi ngaphansi kwezimo ezifanele.

- Kuzinhlelo zokusebenza ezinkulu noma ezidinga kakhulu: Uma iphrojekthi yakho idinga ukusebenza kahle okukhulu, ikakhulukazi ngaphansi kokushintsha kwezimo zokukhanya, isilawuli se-MPPT siyisinqumo esingcono. Ukusebenza okuthuthukisiwe nokusebenza ezimeni eziphansi zokukhanya kwenza izilawuli ze-MPPT zilungele ukuqinisekisa ukuthi izibani zakho ezikhanyayo eziphuzi zelanga zihlala zisebenza ngokwethembeka.

Ekuphetheni

Njengomphakeli othenjwayo wokukhanya kwelanga okuphuzi okubenyezelayo, i-Qixiang izibophezele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu nesiqondiso sochwepheshe ukuze ikusize wenze ukukhetha okungcono kakhulu kwelanga. Kungakhathaliseki ukuthi ukhetha isilawuli se-PWM noma se-MPPT, ukuqonda umehluko nezinzuzo zayo ngayinye kungasiza ekukhetheni isixazululo esilungile sesistimu yakho yokukhanya okukhanyayo okuphuzi kwelanga.

Ukuze uthole ikhwothi yomuntu siqu noma usizo olwengeziwe ekukhetheni okulungileukukhanya okukhanyayo okuphuzi kwelanga nesilawulingephrojekthi yakho, sicela ukhululeke ukuxhumana ne-Qixiang. Silapha ukuze sikunikeze izixazululo ezinokwethenjelwa zelanga ukuze ukhanyise indlela yakho!
