Ngokucaciswa kancinci kancinci kwemigaqo-nkqubo yeephaneli zelanga ezisasazwayo, ishishini le-photovoltaic lasekhaya lizisa indawo entsha yembali kwaye lijongene nemingeni namathuba angazange abonwe ngaphambili. Lo mgaqo-nkqubo ufuna ukuba ngo-2030, zonke ii-photovoltaic ezisasazwayo, kuquka ne-photovoltaic yasekhaya, kufuneka zithathe inxaxheba ngokupheleleyo kwintengiselwano yemarike. Olu tshintsho lomgaqo-nkqubo alupheleli nje ekubumbeni imeko-bume yeshishini, kodwa lukwabeka isiseko sophuhliso lwexesha elizayo.
Imingeni: Ukulinda nokubona imarike kunye nemida yobuchule
Nangona amandla asandul’ ukufakwa e-photovoltaic yasekhaya afikelele phantse kwi-16GW kwisiqingatha sokuqala salo nyaka, ukukhula kuye kwehla xa kuthelekiswa nedatha ye-21GW kwixesha elifanayo kunyaka ophelileyo. Olu hlobo lubangelwa kakhulu yindlela abatyali-mali abakhulu abanjengoosomashishini bakarhulumente abaphambili, amashishini aseburhulumenteni basekuhlaleni kunye namaziko emali malunga neempahla zeephaneli zelanga zasekhaya, nto leyo ekhokelele ekucothweni kokwandiswa kweenkampani zemarike eziphambili. Ukongeza, imida yomthamo we-transformer nayo yingxaki esebenzayo ethintela uphuhliso lweephaneli zelanga zasekhaya. Nangona kunjalo, ngokwembono yesizwe, inani eliqokelelweyo leenkqubo ze-photovoltaic zasekhaya ezifakiweyo limalunga neeseti ezi-5 yezigidi kuphela, kwaye umlinganiselo womthamo ofakiweyo usengaphantsi kwe-10% xa kuthelekiswa namathuba emarike eeseti ezingama-80 ezigidi, nto leyo ebonisa ukuba indawo yemarike isenkulu kwaye amandla awakasetyenziswa.
Amathuba: Inkxaso yomgaqo-nkqubo kunye namathuba emarike
Nangona kukho imingeni, ikamva leshishini le-photovoltaic lasekhaya lisazele ngamathuba. Okokuqala, ulwalathiso olucacileyo lomgaqo-nkqubo lubonelela ngolindelo oluzinzileyo kushishino. I-photovoltaic yasekhaya yabantu bendalo iya kunandipha imodeli yokuthenga eqinisekisiweyo ukuqinisekisa imbuyekezo ezinzileyo, ngelixa i-photovoltaic yasekhaya yabantu abangengabo bendalo ikhuthazwa ukuba iqhagamshelwe ngokupheleleyo kwigridi kwaye iqhagamshele umbane ongaphezulu owenziweyo kwaye usetyenziswe ngabo, nto leyo ekhuthaza ngakumbi amandla emarike. Ngokukodwa, uphuhliso olukhawulezayo lwe-photovoltaic yasekhaya kubantu abangengabo bendalo luye lwaba ngumkhwa ophambili okwangoku. Uninzi lwamaphondo luthathe imodeli yokufaka izicelo zomntu osemthethweni, ekhuthaze ukubekwa emgangathweni koshishino. Okwesibini, ukukhula okuqhubekayo kwemfuno yemarike kubonelela ngendawo ebanzi yophuhliso lwe-photovoltaic yasekhaya. Ngokukhula kwemfuno yamandla acocekileyo kulo lonke ilizwe, ngakumbi ukunikezelwa kombane oqinileyo kwiindawo eziphuhlileyo zonxweme olusemzantsi-mpuma, uzinzo lwexabiso lombane lweeprojekthi ze-photovoltaic zasekhaya luqinisekisiwe, ngaloo ndlela kwandisa ukuzithemba kwabatyali-mali. Kulindeleke ukuba ubungakanani bokufakelwa kwe-photovoltaic yasekhaya kulo nyaka kulindeleke ukuba bufikelele kwi-18GW, kwaye imakethi izaliswe ngamathemba anethemba lophuhliso lwexesha elizayo.
Amathemba eentengiselwano ezisekelwe kwimarike
Umgaqo-nkqubo wentengiselwano ozayo osekelwe kwimarike uza kuba nefuthe elikhulu kwishishini le-photovoltaic lasekhaya. Kwelinye icala, unokubangela ukuba abanye abathathi-nxaxheba abangakhuphisani kangako baphume kwimarike baze bakhuthaze ukusinda kwabo banamandla kushishino; kwelinye icala, kuya kuqhuba ishishini ukuba liphuhle ngendlela esebenza kakuhle nesemgangathweni. Ngokukhula kotshintsho kwimarike yamandla, i-avareji yesizwe yereturn efanelekileyo yangaphakathi (IRR) yeeprojekthi ze-photovoltaic zasekhaya kulindeleke ukuba izinze phakathi kwe-6% kunye ne-7%, inike abatyali-mali ulindelo oluzinzileyo lwereturn.
Ngokubanzi, iiphaneli zelanga kushishino lwasekhaya zikwixesha elibalulekileyo lotshintsho, kunye nemingeni namathuba akhoyo. Ngeli xesha, abathathi-nxaxheba kushishino kufuneka bahlale benolwazi olunzulu lwemarike kunye nokuzithemba okuqinileyo, kwaye bazivumelanise ngokukhutheleyo notshintsho lwemarike kunye nohlengahlengiso lwemigaqo-nkqubo. Kwangaxeshanye, ukuqinisa ubuchule betekhnoloji kunye nolawulo lweendleko, kunye nokuphucula ukhuphiswano kunye nenzuzo yeeprojekthi kuya kuba sisitshixo sokufezekisa uphuhliso oluzinzileyo. Ndikholelwa ukuba phantsi kwesikhokelo semigaqo-nkqubo kwaye iqhutywa yimfuno yemarike, ishishini le-photovoltaic lasekhaya ngokuqinisekileyo liya kuzisa ikamva eliqaqambileyo.
