- I-US inokufikelela kwiinjongo zayo ze-decarbonization ngokukhawuleza ukuba i-c-Si ikhonkco lokubonelela ngelanga lendawo ngokupheleleyo, ngokutsho kophando lobuNjineli baseCornell.
- Ngo-2030, ukukhutshwa kwe-GHG kunokuhla ngama-30% ngo-2020 kwaye ngo-2050 iya kuba yehle ngama-33%.
- Ireshore ngokupheleleyo i-c-Si yemveliso yekhonkco e-US iya kunceda imarike ukunciphisa imingeni enxulumene nokuphazamiseka kwemveliso, ukukhuphisana nemfuno evela kwamanye amashishini okanye amazwe.
Ukuba ukuveliswa kweephaneli zesola kungabuyela ngokupheleleyo e-US ngo-2035, ukukhutshwa kwe-GHG okunesiphumo kungehla nge-30% kwaye ukusetyenziswa kwamandla kuya kuncipha nge-13% ngo-2020, ngokutsho kweYunivesithi yase-Cornell, enokunceda ilizwe lifezekise iinjongo zalo zokukhupha ikhabhoni ngokukhawuleza kunye nokunciphisa utshintsho lwemozulu ngokukhawuleza.
Ngaphezu koko, ukuba imveliso ekujoliswe kuyo ifunyenwe ngo-2050, utshintsho lwemozulu kunye neempembelelo zamandla zinokuthi zehle ngama-33% kunye ne-17%, ngokulandelelanayo xa kuthelekiswa no-2020.
Ukuvelisa iiphaneli ze-PV zekristalline (c-Si) elizweni ziyakukhathalela imingeni yolungiselelo kwaye kwakhona zehlise ukukhutshwa kwe-GHG, ngokutsho kophando lobuNjineli baseCornell. UkuReshoring iSilicon Photovoltaics Manufacturing iGalela kwi-Decarbonization kunye noNciphiso loTshintsho lweMozulu.. Yapapashwa kwi Nature Communications.
"Njengoko iiphaneli ze-photovoltaic zelanga zivela njengomthombo wamandla omkhulu oya kubonisa imarike yamandla e-US kwintsalela ye-21.st kwinkulungwane, iiphaneli zokuvelisa kunye nokukhangela apha ziya kuhambelana neethagethi zethu zemozulu kunye neenjongo zethu zomgaqo-nkqubo wamandla, utshilo uMbhali wephepha uHaoyue Liang.
ISolar ijolise ekuphenduleni i-40% yemfuno yombane yesizwe yase-US ngo-2035 enokuthi inyuke ngakumbi ukuya kwisiqingatha salo lonke unikezelo lombane ngo-2050.
NgoMthetho wokuNcitshiswa kokunyuka kwamaxabiso ezinto (i-IRA) ebonelela ngenkuthazo eyimfuneko kwimveliso yelanga yasekhaya ukuze inyuke, ababhali bophando bajonge iimpembelelo zemozulu kwishedyuli yokulibaziseka kokubuyisela umhlaba.
Iqela lenze uphononongo oluthelekisayo nolulindelekileyo lomjikelo wobomi (LCA) kwiimeko ezininzi zokwenziwa konxweme kunye neemeko zemveliso zangaphandle ukuhlola amandla kunye neempembelelo zemozulu e-US isusa ngokupheleleyo izixhobo zangaphandle.
Uthelekiso lwenziwe phakathi kwemeko engaselunxwemeni ngo-2020 kunye netyala langaphandle kwangaloo nyaka ukuphanda ifuthe lokutshintsha ukusuka kwimveliso yangaphandle ukuya kwimveliso yasekhaya yeepaneli ze-c-Si.
“Xa kuthelekiswa nokuxhomekeka kunikezelo lwehlabathi (kwimeko engaselunxwemeni) ngo-2020, ukwenziwa kwasekhaya kweemodyuli ze-c-Si PV e-US kunciphisa ukukhutshwa kweGHG nge-23% kunye nokusetyenziswa kwamandla nge-4%. Ityala elingaselunxwemeni ngo-2020 ikakhulu lalixhomekeke kwizinto ezivela eMalaysia (38%), Vietnam (21%), Thailand (17%), South Korea (9%), China (6%), naseSingapore (3%),” lifundeka eli phepha.
Abaphandi benza 'uqikelelo olunengqiqo' lweemeko ezibandakanya unikezelo lwasekhaya lwase-US olusekelwe kwiiphaneli zelanga ezinokuphuhlisa isixokelelwano sobonelelo olukhuphisanayo kwimimandla efana ne-Alabama, iFlorida neGeorgia.
Ukuchaza ukuba akukho teknoloji ye-PV inokuthi ithathe indawo ye-c-Si 'ngokukhawuleza ngokwaneleyo' ukuze i-US ifezekise i-decarbonization yecandelo lamandla ngo-2035, abaphandi baxoxa ukuba ukuphuhlisa ikhonkco lokubonelela lasekhaya leemodyuli ze-c-Si ukunciphisa imingeni enxulumene nokuphazamiseka kwemveliso, ukukhuphisana nemfuno evela kwamanye amashishini okanye amazwe, kunye nokugcina ubunkokeli obuqinileyo bokuvelisa amandla elanga e-US.
Nangona kunjalo, kubonakala ngathi i-US yokuvelisa i-solar iya kusekwa ngokukhawuleza ngenxa ye-IRA. Iinkampani ezininzi ze-PV zibhengeze ukuba zisete iifektri ze-PV kwezi nyanga zimbalwa zidlulileyo, eyokuqala, iHanwha Q Cells yaseKorea, ide icwangcise ilaphu elidityanisiweyo elithe nkqo-ukusuka kwi-wafers ukuya kwiimodyuli. Kwiveki ephelileyo kuphela, iinkampani ze-2 ezivela e-China zibhengeze izicwangciso zokuseka ukuveliswa kwemodyuli e-US, kubandakanywa neyona nkampani inkulu ye-PV yehlabathi, i-LONGi Group; enye yayinguHounen, izicwangciso zokupapasha zemodyuli ye-1 GW eSouth Carolina.
