Ingabe amaphaneli elanga ayi-AC noma i-DC?

Uma kufikaamaphaneli elanga, omunye wemibuzo evame kakhulu abantu abayibuzayo ukuthi bakhiqiza ugesi osebenzisa i-alternating current (AC) noma i-direct current (DC). Impendulo yalo mbuzo ayilula njengoba umuntu angase acabange, njengoba kuncike ohlelweni oluthile kanye nezingxenye zalo.

Okokuqala, kubalulekile ukuqonda imisebenzi eyisisekelo yamaphaneli elanga. Amaphaneli elanga aklanyelwe ukuthwebula ukukhanya kwelanga futhi akuguqule abe ugesi. Le nqubo ihilela ukusetshenziswa kwamaseli e-photovoltaic, okuyizingxenye zamaphaneli elanga. Lapho ukukhanya kwelanga kushaya la maseli, akhiqiza amandla kagesi. Kodwa-ke, uhlobo lwalokhu lwamanje (AC noma i-DC) luncike kuhlobo lwesistimu lapho ama-solar panel afakwe khona.

Ezimweni eziningi, ama-solar panel akhiqiza ugesi we-DC. Lokhu kusho ukuthi i-current igeleza ibheke ohlangothini olulodwa isuka kuphaneli, iye ku-inverter, bese iyiguqulela ekubeni yamanje eshintshanayo. Isizathu siwukuthi izinto eziningi zasendlini kanye negridi ngokwayo isebenza ngamandla e-AC. Ngakho-ke, ukuze ugesi okhiqizwe ama-solar panel uhambisane nengqalasizinda kagesi evamile, udinga ukuguqulwa kusuka kumanje oqondile kuya ku-alternating current.

Yebo, impendulo emfushane yombuzo othi "Ingabe amaphaneli elanga ayi-AC noma i-DC?" Isici ukuthi bakhiqiza amandla e-DC, kodwa lonke uhlelo lusebenza ngamandla e-AC. Yingakho ama-inverters eyingxenye ebalulekile yezinhlelo zamandla elanga. Abagcini nje ngokuguqulela i-DC ibe yi-AC, kodwa futhi baphatha okwamanje futhi baqinisekise ukuthi ivunyelaniswa negridi.

Kodwa-ke, kufanelekile ukuqaphela ukuthi kwezinye izimo, amaphaneli elanga angalungiswa ukuze akhiqize amandla e-AC ngokuqondile. Lokhu kuvame ukufezwa ngokusebenzisa ama-microinverters, ama-inverter amancane afakwe ngqo kuma-solar panels ngamanye. Ngalokhu kusetha, iphaneli ngayinye iyakwazi ukuguqula ngokuzimele ukukhanya kwelanga kube okwamanje okushintshanayo, okunikeza izinzuzo ezithile mayelana nokusebenza kahle nokuguquguquka.

Ukukhetha phakathi kwe-inverter emaphakathi noma i-microinverter kuncike ezicini ezihlukahlukene, njengobukhulu nokuhlelwa kwe-solar array, izidingo ezithile zamandla zesakhiwo, kanye nezinga lokuqapha uhlelo oludingekayo. Ekugcineni, isinqumo sokuthi kufanele kusetshenziswe amaphaneli elanga e-AC noma e-DC (noma inhlanganisela yalokhu okubili) sidinga ukucatshangelwa ngokucophelela nokubonisana nochwepheshe oqeqeshiwe welanga.

Uma kuziwa ezindabeni ze-AC vs. DC ezinamaphaneli elanga, okunye ukucatshangelwa okubalulekile ukulahlekelwa amandla. Noma nini lapho amandla eguqulwa esuka kolunye uhlobo aye kolunye, kuba nokulahlekelwa okungokwemvelo okuhlobene nenqubo. Ezinhlelweni zamandla elanga, lokhu kulahlekelwa kwenzeka ngesikhathi sokuguqulwa kusuka kumanje oqondile kuya kumanje oshintshanayo. Sengikushilo lokho, intuthuko kubuchwepheshe be-inverter kanye nokusetshenziswa kwezinhlelo zokugcina ezihlanganisiwe ze-DC kungasiza ekunciphiseni lokhu kulahlekelwa futhi kuthuthukise ukusebenza kahle okuphelele kwesistimu yakho yelanga.

Eminyakeni yamuva nje, kuye kwaba nesithakazelo esikhulayo ekusetshenzisweni kwezinhlelo ze-DC-coupled solar + storage. Lezi zinhlelo zihlanganisa amaphaneli elanga nesistimu yokugcina ibhethri, wonke asebenza ohlangothini lwe-DC lwesibalo. Le ndlela inikeza izinzuzo ezithile mayelana nokusebenza kahle nokuguquguquka, ikakhulukazi uma kuziwa ekuthumbeni nasekugcineni amandla elanga amaningi ukuze asetshenziswe kamuva.

Kafushane, impendulo elula yombuzo othi "Ingabe amaphaneli elanga ayi-AC noma i-DC?" ibonakala ngokuthi bakhiqiza amandla e-DC, kodwa lonke uhlelo lusebenza ngamandla e-AC. Kodwa-ke, ukucushwa okukhethekile kanye nezingxenye zesistimu yamandla elanga kungahluka, futhi kwezinye izimo, amaphaneli elanga angacushwa ukuze akhiqize amandla e-AC ngokuqondile. Ekugcineni, ukukhetha phakathi kwamaphaneli elanga e-AC kanye ne-DC kuncike ezicini ezihlukahlukene, okufaka phakathi izidingo zamandla eziqondile zendawo kanye nezinga lokuqapha isistimu elidingekayo. Njengoba inkambu yelanga iqhubeka nokuvela, cishe sizobona izinhlelo zamandla elanga e-AC kanye ne-DC ziqhubeka nokushintsha ngokugxila ekuthuthukiseni ukusebenza kahle, ukwethembeka, nokusimama.

Uma unentshisekelo kuma-solar panel, wamukelekile ukuthintana nomkhiqizi we-photovoltaic Radiance ukuzethola isaphulelo.
