Izilawuli zentlawulo yelanga okanye izilawuli zizixhobo ezisetyenziswa kwizibane ezisebenza ngelanga ukulawula amandla ombane aphuma kwiphaneli yelanga ukuya ebhetrini. Izilawuli zeSolar zikwanoxanduva lokucutha langoku elitsalwa kwibhetri ukuya kwi-LED. Kwinkqubo yokukhanyisa ilanga, abalawuli badlala indima ebalulekileyo ekulawuleni intlawulo kunye ne-voltage. Xa iipaneli zelanga ziyeka ukuvelisa amandla ekutshoneni kwelanga, abalawuli banceda ukuguqula i-LED.
Kukho ithuba lokuba umbane ugeleza ngasemva ukusuka kwibhetri ukuya kwiipaneli xa kungekho mbane owenziwe ebusuku, onokulimaza ubomi beebhetri. Izilawuli zokutshaja zinceda ekuthinteleni oku kuhamba kombane umva ngokubona xa kungekho mveliso yamandla kunye nokukhupha iipaneli kwiibhetri ukunqanda ukutshaja. Ukutshaja kakhulu kunokunciphisa ubomi beebhetri kwaye izilawuli zentlawulo zanamhlanje zinceda ekwandiseni ubomi bebhetri ngokunciphisa umthamo wangoku ofakwa kwibhetri xa igcwaliswe ngokupheleleyo kwaye ikwancedise ekuguquleni amandla ombane agqithisileyo abe yi-amperage.
Kutheni kufuneka abalawuli kwizibane zelanga?
●Ukulawula amandla ombane ebhetri
●Ukuthintela ukubuya umva kwangoku
●Ukuthintela ukutshajiswa nokutshajiswa ngaphantsi kweebhetri
●Ukubonisa ukuba ibhetri itshajwe nini
Iindidi zezilawuli zentlawulo yelanga
I-Pulse Width Modulation (PWM) abalawuli bentlawulo
I-PWM sesona silawuli sisetyenziswa ngokuqhelekileyo njengoko isebenzisa iteknoloji evavanywe ixesha ukulawula ukuhamba kwangoku. Ukumodareyitha kobubanzi be-Pulse kwenzeka xa ibhetri ifikelela kwinqanaba lokutshaja elilungeleleneyo ngokunciphisa ikhoyo kancinci kancinci. Ukuzikhupha ngokwako yingxaki eqhelekileyo kwiibhetri ezininzi ezinokutshajwa kwakhona apho zikholisa ukuphelelwa ngamandla xa sele zihlawuliswe ngokupheleleyo. Umlawuli we-PWM uqala kwakhona ukubonelela ngexabiso elincinci lamandla rhoqo ukuze kugcinwe ibhetri igcwele kwaye igcine intlawulo, ngaloo ndlela inqanda ukuzikhupha.
Abalawuli be-PWM babonwa njengexesha elide kakhulu kwaye baqhuba kakuhle kwiindawo ezifudumeleyo. Amaxabiso aphantsi kakhulu kwaye ayafumaneka ngobukhulu obuninzi kwiintlobo ezahlukeneyo zezicelo. Ngabalawuli be-PWM, kubalulekile ukuba neepaneli zelanga kunye neebhetri ezinombane ohambelanayo. Isilawuli sentlawulo ye-PWM luhlobo oluqhelekileyo lolawulo lwentlawulo olusetyenziswa ekukhanyeni kwesitrato selanga kwaye ikwafaneleka kakuhle kwiinkqubo ezincinci zelanga kunye neepaneli ezincinci kunye nebhetri.
Ubuninzi bolawulo lwamandla okulandelela (MPPT) intlawulo
Abalawuli beMPPT lukhetho olubiza kakhulu kwaye luyinkimbinkimbi kwiinkqubo zelanga; nangona kunjalo, enye yeenzuzo ezinkulu zala balawuli ayifani nabalawuli be-PWM, abalawuli beMPPT banokufanisa ii-voltages ezingahambelaniyo ezivela kwiipaneli zelanga kunye neebhetri. Ubuchule obusetyenziswa kubalawuli beMPPT butsha obuvumela iiphaneli ukuba zisebenze kwindawo yazo yamandla aphezulu. Ngenxa yeqondo elahluka-hlukeneyo lemitha yelanga yonke imini, amandla ombane wephaneli kunye nombane unokwahluka. Abalawuli beMPPT bahlengahlengisa amandla ombane ukuze bavelise amandla aphezulu kungakhathaliseki ukuba zithini na iimeko zemozulu.
Abalawuli beMPPT bahlawula ngokukhawuleza kwaye banobomi obude. Bayakwazi ukulungelelanisa igalelo labo ukuze baqalise amandla amaninzi anokwenzeka kwiipaneli. Aba balawuli bayakwazi ukutshintsha amandla emveliso ukuze batshatise amandla ebhetri. Ziyabonwa ukuba zisebenza ngcono kwiindawo ezibandayo kwaye zithathwa njengezisebenza kakuhle kunabalawuli be-PWM.
Indlela yokukhetha umlawuli wentlawulo efanelekileyo?
Zombini i-PWM kunye nezilawuli zentlawulo zeMPPT zisetyenziswa kwinkqubo yokukhanya ezitalatweni zelanga. Abalawuli basebenza njengesixhobo sokukhusela kwaye bakhuphe okona kulungileyo kwiyunithi yakho yelanga. Ngokusekwe kwezi zinto zilandelayo, kuya kufuneka ukhethe isilawuli esihambelana nombane wakho welanga.
