Imakethe ye-solar water heater yomhlaba wonke ibheke esigabeni sokunwetshwa.Lokhu kudalwe ukwanda okukhulu kwesidingo esivela kubasebenzisi bezindawo zokuhlala nezohwebo.Ngaphezu kwalokho, ukwenyuka kokukhathazeka okuvela kohulumeni emazweni asafufusa, njengeChina, India, kanye neSouth Korea, mayelana nezinkambiso zokukhishwa kwe-zero kulindeleke ukuthi kuqhubekisele phambili ukukhula kwemakethe.
I-heater yamanzi yelanga iyisisetshenziswa, esithatha ukukhanya kwelanga ukushisa amanzi.Iqoqa ukushisa ngosizo lomqoqi welanga, futhi ukushisa kudluliselwa ku-tank yamanzi ngosizo lwepompo elijikelezayo.Isiza ekusetshenzisweni kwamandla njengoba amandla elanga ekhululekile ngokungafani nezinsiza zemvelo ezifana negesi yemvelo noma izibaseli ezimbiwa phansi.
Ukwanda kwesidingo samasistimu okushisa amanzi ezindaweni ezingazodwa nasemaphandleni kulindeleke ukuthi kuqhubekisele phambili ukukhula kwemakethe.Izishisi zamanzi zelanga ezincane zisetshenziswa kakhulu ezindaweni zasemakhaya ngenxa yezindleko eziphansi kanye nokusebenza kahle okuphezulu kwezimo zezulu ezahlukahlukene.Isibonelo, iShayina inabakhiqizi abacishe babe ngu-5,000 abakhiqizi bamanzi elanga aphakathi nendawo futhi iningi labo lisebenza ezindaweni zasemakhaya.Ngaphezu kwalokho, ukwesekwa okukhulu kukahulumeni mayelana nezaphulelo nezinhlelo zamandla kulindeleke ukuthi kuqhubeke nokuheha amakhasimende amasha, ngaleyo ndlela kuthuthukise ukukhula kwemakethe.
Ngokusekelwe ohlotsheni, ingxenye ecwebezelayo yavela njengomholi wemakethe, ngenxa yokusebenza kahle okuphezulu kwabaqoqi abacwebezelwe uma kuqhathaniswa nabaqoqi abangacwebezeli.Kodwa-ke, intengo ephezulu yabaqoqi abacwebezelwe ingase ikhawulele ukusetshenziswa kwabo ezinhlelweni ezincane.
Ngokusekelwe kumthamo, ingxenye yomthamo wamalitha ayi-100 ibalwe ngesabelo semakethe esibalulekile.
Lokhu kubangelwa ukwenyuka kwesidingo endaweni yokuhlala.I-heater yamanzi yelanga engabizi kakhulu enamandla angu-100-litre yanele umndeni wamalungu angu-2-3 ezakhiweni zokuhlala.
Ingxenye yendawo yokuhlala yesifudumezi samanzi elanga ibe nesabelo esibalulekile semakethe, ngenxa yokutshalwa kwezimali okuqinile emkhakheni wezokwakha ukuze kumiswe kabusha futhi kulungiswe izakhiwo.Eziningi zalezi zakhiwo ezintsha zinemigqomo yelanga efakwe ophahleni, exhunywe ethangini lamanzi ngepompo elijikelezayo.
INyakatho Melika yaba nesabelo semakethe esibalulekile, ngenxa yezinyathelo zikahulumeni ezivumayo zokuthuthukisa ubuchwepheshe bamandla elanga ezindaweni zokuhlala nezentengiso.
Okutholakele okubalulekile kocwaningo
- Isifudumezi samanzi esicwebezelwe kulindeleke ukuthi sikhule ku-CAGR ephakeme kakhulu cishe engu-6.2%, ngokwemali engenayo, ngesikhathi sokubikezela.
- Ngomthamo, enye ingxenye kulindeleke ukuthi ikhule nge-CAGR ka-8.2%, ngokwemali engenayo, ngesikhathi sokubikezela.
- I-Asia-pacific ibibusa imakethe ngamasheya emali engenayo acishe abe ngu-55% ngo-2019.
