I-MPPT vs. PWM: Sesiphi isilawuli esilungele isibane esidanyazayo selanga?

Kwintsimi yezisombululo zelanga,izibane ezidanyazayo zelangaziye zaba yinxalenye ebalulekileyo yezicelo ezahlukeneyo ezibandakanya ulawulo lwezithuthi, iindawo zokwakha, kunye neempawu ezingxamisekileyo. Njengomboneleli onamava wezibane ezidanyazayo zelanga, uQixiang uyakuqonda ukubaluleka kokukhetha umlawuli ofanelekileyo wokwandisa ukusebenza kwezi zibane. Kukho iintlobo ezimbini eziphambili zabalawuli bentlawulo yelanga ezisetyenziswa ngokuqhelekileyo kwizicelo zelanga: Ubuninzi boMbane waMandla oMbane (MPPT) kunye nePulse Width Modulation (PWM). Eli nqaku liza kuntywila kumahluko phakathi kweMPPT kunye nabalawuli be-PWM kwaye likuncede uthathe isigqibo sokuba ngowuphi umlawuli olungele iimfuno zakho zokukhanya okudanyazayo kwelanga.

Funda malunga nezilawuli zentlawulo yelanga

Ngaphambi kokuba ungene kuthelekiso, kubalulekile ukuqonda ukuba yintoni eyenziwa ngumlawuli welanga. Ezi zixhobo zilawula i-voltage kunye nezangoku ukusuka kwiipaneli zelanga ukuya kwibhetri, ukuqinisekisa ukuba ibhetri ihlawuliswe ngokufanelekileyo nangokukhuselekileyo. Ukukhetha isilawuli kunokuchaphazela kakhulu ukusebenza kunye nobomi obude benkqubo yakho yokukhanya etyheli yelanga.

Abalawuli bePWM

Izilawuli ze-Pulse width modulation (PWM) lolona hlobo lwemveli lwesilawuli sentlawulo yelanga. Basebenza ngokudibanisa iphaneli yelanga ngokuthe ngqo kwibhetri kwaye basebenzise uluhlu lweempawu zokutshintsha ukulawula inkqubo yokutshaja. Ububanzi bophawu "luvuliwe" luhlengahlengisa ngokusekelwe kwimeko yebhetri yentlawulo, ivumela inkqubo yokutshaja ezinzileyo nelawulekayo.

Izinto eziluncedo zabalawuli be-PWM:

1. Ilula kwaye ayinaxabiso:

Abalawuli be-PWM babiza ixabiso eliphantsi kwaye kulula ukuyifaka kunabalawuli beMPPT. Oku kubenza babe ukhetho olunomtsalane kwiiprojekthi zohlahlo lwabiwo-mali.

2. Ukuthembeka:

Ngenxa yamacandelo ambalwa kunye noyilo olulula, abalawuli be-PWM bakholisa ukuthembeka ngakumbi kwaye bafuna ukugcinwa okuncinci.

3. Ubuchule kwiiNkqubo ezincinci:

Kwiinkqubo ezincinci zelanga apho i-voltage yepaneli yelanga ihambelana ngokusondeleyo nombane webhetri, ukusebenza kakuhle komlawuli we-PWM kuphezulu kakhulu.

Abalawuli beMPPT

Abalawuli be-Maximum Power Point Tracking (MPPT) bubuchwephesha obuphezulu kakhulu obuphakamisa amandla okuvuna kwiiphaneli zelanga. Bahlala bebeka iliso ekuphumeni kweepaneli zelanga kwaye bahlengahlengise indawo yokusebenza yombane ukuze kuqinisekiswe ukuba amandla aphezulu akhutshwa.

Izinto eziluncedo zoMlawuli weMPPT:

1. Ukusebenza okuphezulu:

Xa kuthelekiswa nabalawuli be-PWM, abalawuli be-MPPT banokunyusa ukusebenza kakuhle kweenkqubo zelanga ukuya kuthi ga kwi-30%, ngakumbi xa i-voltage ye-solar panel iphezulu kunombane webhetri.

2. Ukusebenza ngcono kwiimeko zokukhanya okuphantsi:

Umlawuli weMPPT wenza kakuhle kwiimeko eziphantsi zokukhanya, okwenza kube yinto efanelekileyo kwimitha yelanga emthubi ekufuneka isebenze ngokufanelekileyo nangeentsuku ezinamafu okanye ngorhatya.

3. Ububhetyebhetye boyilo lwenkqubo:

Abalawuli beMPPT bavumela ukuguquguquka okukhulu kwindlela yokuyila ukusebenzisa iipaneli zelanga eziphezulu zombane, ezinokunciphisa iindleko zocingo kunye nokulahlekelwa.

Sesiphi isilawuli esilungele ukukhanya okutyheli kwelanga?

Xa ukhetha iMPPT kunye nabalawuli be-PWM bokukhanya okutyheli elanga, isigqibo sixhomekeke kakhulu kwiimfuno ezithile zesicelo sakho.

- KwiiProjekthi eziNcinane, eziMiselwe kuHlahlo-lwabiwo-mali: Ukuba usebenza kwiprojekthi encinci enohlahlo lwabiwo-mali olulinganiselweyo, umlawuli we-PWM unokwanela. Zithembekile, zingabizi kakhulu, kwaye zinokubonelela ngamandla aneleyo kwizibane ezidanyazayo zelanga ezimthubi phantsi kweemeko ezifanelekileyo.

- Kwizicelo ezinkulu okanye ezifuna kakhulu: Ukuba iprojekthi yakho ifuna ukusebenza kakuhle, ngakumbi phantsi kweemeko zokukhanya eziguqukayo, umlawuli weMPPT lolona khetho lungcono. Ukonyuka kokusebenza kunye nokusebenza kwiimeko zokukhanya okuphantsi kwenza abalawuli beMPPT balungele ukuqinisekisa ukuba izibane zakho ezidanyazayo zelanga zihlala zisebenza ngokuthembekileyo.
