Abaphandi beYunivesithi yaseMichigan baye bafumanisa ukuba ixabiso le-solar ephahleni liza kunyuka phakathi kwe-5% kunye ne-15% phakathi kwekhulu leminyaka kuluhlu lwezixeko zase-US phantsi kokutshintsha kwemozulu ephakathi, kwaye ukuya kuthi ga kwi-20% ekupheleni kwenkulungwane.
Abaphandi abavela kwiYunivesithi yaseMichigan baye bafumanisa ukuba utshintsho lwemozulu luya kwandisa ixabiso lexesha elizayo leepaneli zelanga eziphezu kophahla kulo lonke elase-United States ukuya kuthi ga kwi-20% ekupheleni kwenkulungwane.
Kwi "Utshintsho lweMozulu luya kuba nefuthe kwixabiso kunye nokwamkelwa ngokufanelekileyo kwe-solar yokuhlala kwi-rooftop solar," esandul 'ukupapashwa kwiNguquko yeMozulu yeNdalo, abaphandi balinganisa imiphumo yokutshintsha kwemozulu kwixabiso lelanga lophahla kunye nomthamo ofanelekileyo. Bahlalutye idatha esuka kumakhaya angama-2,000 kwiidolophu ze-17 zase-US, ukuqikelela imfuno yomoya-moya kunye nokusebenza kweepaneli zelanga phantsi kwemozulu ezayo.
U-Mai Shi, umbhali okhokelayo wesifundo, uxelele pv imagazini ukuba olu luphononongo lokuqala ukulinganisa ukuba utshintsho lwemozulu luya kuchaphazela njani ixabiso le-PV yophahla kumakhaya kwixesha elizayo.
“Ixabiso apha lithetha ixabiso lezoqoqosho – ingaba ikhaya lilondoloza malini kwityala lalo lombane xa lifakela isola eluphahleni,” ucacise watsho uShi. "Uhlalutyo lwethu lubonisa indlela utshintsho lwemozulu oluya kuyichaphazela ngayo imfuno yombane wasekhaya ngokunyuka kwemfuno yokupholisa kunye nokuveliswa kwePV kuphahla lwendlu."
Abaphandi bathi ixabiso lelanga eluphahleni liya kunyuka phakathi kwe-5% kunye ne-15% kuluhlu olubanzi lwezixeko zase-US phantsi kokutshintsha kwemozulu phakathi kwenkulungwane, kwaye emva koko ukuya kuthi ga kwi-20% ekupheleni kwenkulungwane. Ixabiso elonyuka kakhulu lahlalutywa kumakhaya anokuqina okupholisa okukhulu kunye nezixeko ezinokwanda kwemitha kunye namaxabiso aphezulu okuthengisa amandla.
Kuzo zonke izixeko ze-17, iMiami kunye ne-Orlando kulindeleke ukuba ibone ukunyuka okunamandla kwixabiso lelanga. UShi uthe kwezi zixeko, utshintsho lwemozulu kulindeleke ukuba lunyuse imitha yelanga, nto leyo eya kuthi ithande ukuveliswa kwePV ngaphezulu kophahla, ngelixa ukonyuka kwamaqondo obushushu omoya kuya kukhokelela kwimfuno yombane wasekhaya.
Abaphandi baye bagqiba ukuba njengoko ixabiso le-PV yophahla linyuka, amandla oqoqosho angcono kumakhaya aya kunyuka. Baqikelela ukonyuka kwamandla nge-5% ukuya kwi-25% ekupheleni kwenkulungwane phantsi kwemeko yemozulu ephakathi. Abaphandi bathi iziphumo zineempembelelo kubathengi be-PV bangoku kunye nekamva elizayo.
“Ngenxa ye-avareji yeminyaka engama-25 yobomi bokufakelwa kwelanga eluphahleni, inkqubo eyakhiwe namhlanje iya kufana namava emozulu angama-2050. Ngoko ke, kubalulekile ukuba amakhaya acinge ngexabiso lekamva xa kusakha isola,” utshilo uShi. "Ukuba amakhaya ayakwenza oko, iziphumo zethu zibonisa ukuba banokubona ixabiso elikhulu kwilanga, kwaye banokuthatha isigqibo sokwakha ngaphezulu."
