I-Rooftop PV iwumthombo wesine ngobukhulu wokukhiqiza ugesi e-Australia, ehlinzeka cishe ngo-11% wamandla kagesi ezweni, kodwa iSunWiz ithi imakethe ibhekene nezinselelo.
Imizi engaphezu kweyodwa kwezintathu zase-Australia isivele ikhiphe i-solar ophahleni kodwa ukuhlaziya okusha okwenziwe inkampani ye-Solar SunWiz kukhombisa ukuthi imakethe ibhekene “nokucindezela kwenzuzo” okubangelwa ukwehla kwamanani entengo yamaphaneli kanye nokwehla kwezinga lokufakwa kwe-PV ophahleni.
Umsunguli we-Sunwiz u-Warwick Johnston uthe ukwehla kokwehla akukabonakali emananini okufakwa ophahleni - kanti isamba sonyaka kuze kube manje sikhuphuke ngo-7% ngesikhathi esifanayo ngonyaka odlule - kodwa kubonakala ngokucacile kwezinye izingcezu zedatha yenkampani.
Idatha ibonisa ukwehla kwamavolumu okuhola, ekuthengisweni, nakumazinga okuguqulwa okuholayo. Amavolomu aholayo ngo-April 2024 abephezulu ngo-10% kunenyanga efanayo eminyakeni emibili edlule - izinga eliphansi kakhulu kusukela ngoDisemba 2022. Iziphakamiso nokuthengiswa bekulokhu kuthrenda ukwehla kusukela ngoJuni 2023 kuyilapho izinga lokuguqulwa lehle laya ku-1.5% ngaphansi kophawu lwango-April 2022 futhi alikakafinyelelwa.
Lokhu kuhambisane nokwehla kwenani lentengo lamaphaneli e-Australia kusuka ku-AUD 0.60 ($0.40) phakathi no-2022 kuya ku-AUD 0.30 manje.
"Umphumela walokhu ukuminyanisa inzuzo," kusho uJohnston. “Amanani angehla kodwa uma amanani enyuka, imali engenayo ingahlala ifana futhi isikhathi esithile lapho ngo-2023 lokho bekuyiqiniso kuma-wholesale front, kodwa amavolumu e-Q1 awile. Kusho ukuthi abathengisi basebenza ngemali encane engenayo.”
Naphezu kokwehla kwamanani amaphaneli, u-Johnston uthe abathengisi nabo bazizwa becindezelekile ngenxa yokwehla kwezinga lokufakwa okuhambisana nokwenyuka kwamanani e-inverter futhi amakhasimende asebenzisa imali encane ngokufaka uphahla ngalunye.
"Sekuyisikhathi eside sibona amakhasimende ajwayelekile ekhokha i-AUD 9,000 yesistimu yelanga ephahleni," esho, ephawula ukuthi njengoba amanani ephaneli ehla, abathengi baqhubeka nokutshala izimali ezifanayo, bekhetha amasistimu amakhulu ngosayizi wesistimu ojwayelekile okhuphuka cishe ku-10.5 kW ngenyanga yokugcina ka-2023. ngenani elifanayo lemali. Manje sibona abantu beqala ukusebenzisa imali encane. ”
ISunWiz ithe ukwehla kwezinga lokufakwa kuhambisana nokunyuka kwezindleko ezihambisana nokukhuphuka kwezindleko zabasebenzi.
Ukwanda kokufakwa kwesistimu yesitoreji samandla ebhethri kunikeza induduzo ethile kubathengisi.
"Abathengisi abaletha i-PV nje bathola imali encane kunaleyo ababenayo kusukela ngo-2019," kusho uJohnston. "Uma benza i-PV namabhethri noma kunjalo, unyaka werekhodi, kodwa nje."
Irekhodi lamasistimu okugcina amandla ebhethri angama-57,000, anamandla ahlanganisiwe angama-656 MWh, afakwa ezindlini zase-Australia ngo-2023, akhuphuke ngo-21% ngonyaka odlule.
Isilinganiso sokufakwa kwamabhethri ekufakweni kwe-solar sikhuphuke ngo-2023, sikhuphukela ku-17% ngohlelo olulodwa lokugcina amandla olufakwe kuzo zonke izinhlelo eziyisithupha zophahla lwe-PV, senyuke ngo-15% ngo-2022.
Naphezu kokukhishwa okurekhodiwe kwamabhethri okuhlala, uJohnston uthe ulindele ukuthi imakethe ibhekane nezinselelo esikhathini esizayo esiseduze.
“Lesi sikhathi asizophela maduze, ngoba labo bashayeli basazoqhubeka,” kusho yena. "Lezi zinselelo ziyinto entsha evamile."
