Xa kufikwa kuiiphaneli zelanga, enye yemibuzo eqhelekileyo abantu abayibuzayo kukuba ngaba bavelisa umbane ngendlela ye-alternating current (AC) okanye i-direct current (DC). Impendulo yalo mbuzo ayilula njengoko umntu enokucinga, njengoko kuxhomekeke kwinkqubo ethile kunye namacandelo ayo.
Okokuqala, kubalulekile ukuqonda imisebenzi esisiseko yeepaneli zelanga. Iiphaneli zelanga ziyilelwe ukuba zibambe ukukhanya kwelanga kwaye ziguqule zibe ngumbane. Le nkqubo ibandakanya ukusetyenziswa kweeseli ze-photovoltaic, eziyinxalenye yeepaneli zelanga. Xa ukukhanya kwelanga kubetha ezi seli, zenza umsinga wombane. Nangona kunjalo, uhlobo lwalo lwangoku (AC okanye i-DC) luxhomekeke kuhlobo lwenkqubo apho iipaneli zelanga zifakwe khona.
Kwiimeko ezininzi, iiphaneli zelanga zivelisa umbane weDC. Oku kuthetha ukuba umsinga uqukuqela kwicala elinye ukusuka kwindawo yolawulo, ukuya kwi-inverter, ethi emva koko iyiguqule ibe ngumsinga otshintshanayo. Isizathu kukuba uninzi lwezixhobo zasekhaya kunye negridi ngokwayo isebenza kumandla e-AC. Ngoko ke, ukuze umbane oveliswa ngeepaneli zelanga uhambelane neziseko zombane eziqhelekileyo, kufuneka uguqulwe ukusuka kumbane othe ngqo ukuya kwi-alternating current.
Ewe, impendulo emfutshane kumbuzo othi "Ngaba iiphaneli zelanga zi-AC okanye i-DC?" Uphawu kukuba bavelisa amandla e-DC, kodwa yonke inkqubo iqhele ukusebenza ngamandla e-AC. Kungenxa yoko le nto ii-inverters ziyinxalenye ebalulekileyo yeenkqubo zamandla elanga. Abagcini nje ukuguqula i-DC kwi-AC, kodwa baphinde balawule okwangoku kwaye baqinisekise ukuba ihambelana negridi.
Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba kwezinye iimeko, iipaneli zelanga zinokulungiswa ukuba zivelise ngokuthe ngqo amandla e-AC. Oku kudla ngokufezekiswa ngokusetyenziswa kwee-microinverters, eziziinverter ezincinci ezifakwe ngokuthe ngqo kwiipaneli zelanga. Ngolu cwangciso, iphaneli nganye iyakwazi ukuguqula ngokuzimeleyo ukukhanya kwelanga kwi-alternating current, enika izibonelelo ezithile malunga nokusebenza kakuhle kunye nokuguquguquka.
Ukhetho phakathi kwe-inverter ephakathi okanye i-microinverter ixhomekeke kwizinto ezahlukeneyo, ezifana nobukhulu kunye nokwakheka kwe-solar array, iimfuno ezithile zamandla zepropati, kunye nenqanaba lokujongwa kwenkqubo efunekayo. Ekugqibeleni, isigqibo sokuba kusetyenziswe iipaneli zelanga ze-AC okanye ze-DC (okanye indibaniselwano yezi zibini) zifuna ukuqwalaselwa ngokucophelela kunye nokubonisana nomntu oqeqeshiweyo welanga.
Xa kuziwa kwimiba ye-AC vs. DC kunye neepaneli zelanga, enye ingcamango ebalulekileyo kukulahlekelwa kwamandla. Nanini na xa amandla eguqulwa ukusuka kwenye indlela ukuya kwenye, kukho ilahleko engokwemvelo ehambelana nenkqubo. Kwiinkqubo zamandla elanga, ezi lahleko zenzeke ngexesha lokuguqulwa ukusuka ngqo ngoku ukuya kwi-alternating current. Emva kokuthetha oko, ukuqhubela phambili kwitekhnoloji ye-inverter kunye nokusetyenziswa kweenkqubo zokugcina ezidityanisiweyo ze-DC kunokunceda ukunciphisa le lahleko kunye nokuphucula ukusebenza kakuhle kwenkqubo yakho yelanga.
Kwiminyaka yakutshanje, kukho umdla okhulayo wokusetyenziswa kwe-DC-coupled solar + storage systems. Ezi nkqubo zidibanisa iipaneli zelanga kunye nenkqubo yokugcina ibhetri, zonke zisebenza kwicala le-DC le-equation. Le ndlela inikezela ngeenzuzo ezithile malunga nokusebenza kakuhle kunye nokuguquguquka, ngakumbi xa kuziwa ekubanjeni nasekugcineni amandla angaphezulu elanga ukuze asetyenziswe kamva.
Isishwankathelo, impendulo elula kumbuzo othi "Ngaba iiphaneli zelanga zi-AC okanye i-DC?" ibonakala ngokuba bavelisa amandla e-DC, kodwa inkqubo iyonke isebenza ngamandla e-AC. Nangona kunjalo, ukucwangciswa okuthe ngqo kunye namacandelo enkqubo yamandla elanga inokwahluka, kwaye kwezinye iimeko, iipaneli zelanga zinokulungiswa ukuba zivelise ngokuthe ngqo amandla e-AC. Ekugqibeleni, ukhetho phakathi kweepaneli zelanga ze-AC kunye ne-DC zixhomekeke kwizinto ezahlukeneyo, kubandakanywa iimfuno zamandla ezikhethekileyo kunye nenqanaba lokuhlola inkqubo efunekayo. Njengoko ibala lelanga liqhubeka nokuvela, siya kubona ukuba iinkqubo zamandla elanga ze-AC kunye ne-DC ziqhubeka nokuguquka ngokugxila ekuphuculeni ukusebenza kakuhle, ukuthembeka, kunye nokuzinza.
Ukuba unomdla kwiipaneli zelanga, wamkelekile ukuba uqhagamshelane nomenzi we-photovoltaic Radiance ukuyafumana isicatshulwa.
