Abantu abaninzi kwishishini le-photovoltaic okanye abahlobo abaqhelene nokuveliswa kombane we-photovoltaic bayazi ukuba ukutyala imali ekufakweni kwezityalo zombane ze-photovoltaic eluphahleni lwezityalo zokuhlala okanye zoshishino kunye nezorhwebo akunakuvelisa umbane kuphela kwaye kufumane imali, kodwa kunokufumana ingeniso entle. Ehlotyeni elishushu, kunokunciphisa ngempumelelo ubushushu bangaphakathi kwezakhiwo. Isiphumo sokuthintela ubushushu kunye nokupholisa.
Ngokweemviwo zamaziko obuchwephesha afanelekileyo, ubushushu bangaphakathi bezakhiwo ezinezityalo zamandla ze-photovoltaic ezifakwe eluphahleni buphantsi ngama-4-6 degrees kunobo bezakhiwo ezingafakelwanga.
Ngaba izitishi zamandla ze-photovoltaic ezifakwe eluphahleni zinganciphisa ubushushu bangaphakathi ngee-degrees ezi-4-6? Namhlanje, siza kukuxelela impendulo ngeeseti ezintathu zedatha ethelekiswayo elinganisiweyo. Emva kokuyifunda, usenokuba nokuqonda okutsha ngesiphumo sokupholisa sezitishi zamandla ze-photovoltaic.
Okokuqala, fumanisa indlela isikhululo samandla se-photovoltaic esinokupholisa ngayo isakhiwo:
Okokuqala, iimodyuli ze-photovoltaic ziya kubonakalisa ubushushu, ukukhanya kwelanga kukhanyisa iimodyuli ze-photovoltaic, iimodyuli ze-photovoltaic zifunxa inxalenye yamandla elanga kwaye ziyiguqule ibe ngumbane, kwaye enye inxalenye yokukhanya kwelanga ibonakaliswa ziimodyuli ze-photovoltaic.
Okwesibini, imodyuli ye-photovoltaic iyawurhoxisa umbane oqikelelweyo, kwaye ukukhanya kwelanga kuya kuncitshiswa emva kokukhanya kwelanga, nto leyo ehluza ngokufanelekileyo ukukhanya kwelanga.
Okokugqibela, imodyuli ye-photovoltaic yenza indawo yokukhusela eluphahleni, kwaye imodyuli ye-photovoltaic inokwenza indawo yomthunzi eluphahleni, nto leyo efezekisa ngakumbi isiphumo sokufakelwa kobushushu kunye nokupholisa uphahla.
Okulandelayo, thelekisa idatha yeeprojekthi ezintathu ezilinganisiweyo ukuze ubone ukuba isikhululo samandla se-photovoltaic esifakwe eluphahleni sinokuphola kangakanani.
1. IZiko loKhuthazo loTyalo-mali kwiNdawo yoPhuhliso loQoqosho noBugcisa yaseDatong elikwinqanaba likaZwelonke, iProjekthi yoPhahla lweZibane zeAtrium
Uphahla olungaphezulu kwama-200 eemitha zesikwere lwe-atrium yeZiko lokuKhuthaza uTyalo-mali leNdawo yoPhuhliso loQoqosho noBugcisa yeSizwe saseDatong lwalwenziwe ngophahla oluqhelekileyo lweglasi ekhazimlayo, olunenzuzo yokuba luhle kwaye lubonakala, njengoko kubonisiwe kumfanekiso ongezantsi:
Nangona kunjalo, olu hlobo lophahla lokukhanyisa luyacaphukisa kakhulu ehlotyeni, kwaye alunakufezekisa isiphumo sokuthintela ubushushu. Ehlotyeni, ilanga elitshisayo lingena kwigumbi ngeglasi yophahla, kwaye liya kuba shushu kakhulu. Izakhiwo ezininzi ezinophahla lweglasi zineengxaki ezinjalo.
Ukuze kufezekiswe injongo yokonga amandla nokupholisa, kwaye kwangaxeshanye kuqinisekiswe ubuhle kunye nokuhanjiswa kokukhanya kophahla lwesakhiwo, umnini ekugqibeleni ukhethe iimodyuli ze-photovoltaic waza wazifaka kuphahla lweglasi lokuqala.
Umfaki ufaka iimodyuli ze-photovoltaic eluphahleni
Emva kokufaka iimodyuli ze-photovoltaic eluphahleni, yintoni isiphumo sokupholisa? Jonga ubushushu obufunyenwe ngabasebenzi bokwakha kwindawo enye kwindawo ngaphambi nasemva kokufakwa:
Kuyabonakala ukuba emva kokufakelwa kwesikhululo samandla se-photovoltaic, ubushushu bomphezulu wangaphakathi weglasi behle ngaphezulu kwama-20 degrees, kwaye ubushushu bangaphakathi nabo behle kakhulu, nto leyo engagcini nje ngokusindisa kakhulu iindleko zombane zokuvula i-air conditioner, kodwa ikwafezekise isiphumo sokonga amandla kunye nokupholisa, kwaye iimodyuli ze-photovoltaic eluphahleni ziya kutsala amandla elanga. Umlambo ozinzileyo wamandla uguqulwa ube ngumbane oluhlaza, kwaye iingenelo zokonga amandla kunye nokwenza imali zibaluleke kakhulu.
2. Iprojekthi yethayile ye-Photovoltaic
Emva kokufunda ngesiphumo sokupholisa seemodyuli ze-photovoltaic, makhe sijonge esinye isixhobo sokwakha esibalulekileyo se-photovoltaic-injani isiphumo sokupholisa seethayile ze-photovoltaic?
Ukuququmbela:
1) Umahluko wobushushu phakathi komphambili nomva wethayile yesamente yi-0.9°C;
2) Umahluko wobushushu phakathi komphambili nomva wethayile ye-photovoltaic yi-25.5°C;
3) Nangona ithayile ye-photovoltaic ifunxa ubushushu, ubushushu bomphezulu buphezulu kunobo bethayile yesamente, kodwa ubushushu obungasemva buphantsi kunobo bethayile yesamente. Ipholile nge-9°C kunethayile zesamente eziqhelekileyo.
(Inqaku elikhethekileyo: Ii-thermometers ze-infrared zisetyenziswa kule rekhodi yedatha. Ngenxa yombala womphezulu wento elinganisiweyo, ubushushu bunokuphambuka kancinci, kodwa ngokusisiseko bubonakalisa ubushushu bomphezulu wento yonke elinganisiweyo kwaye bungasetyenziswa njengesalathiso.)
Phantsi kobushushu obuphezulu obuyi-40°C, ngentsimbi ye-12 emini, ubushushu bophahla babuphezulu buyi-68.5°C. Ubushushu obulinganiswe kumphezulu wemodyuli ye-photovoltaic buyi-57.5°C kuphela, obuphantsi nge-11°C kunobushushu bophahla. Ubushushu be-backsheet yemodyuli ye-PV buyi-63°C, obusephantsi nge-5.5°C kunobushushu bophahla. Phantsi kweemodyuli ze-photovoltaic, ubushushu bophahla obungenalanga ngqo buyi-48°C, obuphantsi nge-20.5°C kunobophahla olungagqunywanga, obufana nokunciphisa ubushushu okufunyenwe yiprojekthi yokuqala.
Ngovavanyo lweeprojekthi ezintathu ze-photovoltaic ezingentla, kunokubonwa ukuba isiphumo sokufakwa kwezityalo zamandla ze-photovoltaic eluphahleni sibaluleke kakhulu, kwaye ungalibali ukuba kukho ingeniso yeminyaka engama-25 yokuvelisa umbane.
Esi sisizathu esiphambili sokuba abanini kunye nabahlali abaninzi bemizi-mveliso kunye nabarhwebi bakhethe ukutyala imali ekufakweni kwezityalo zamandla ze-photovoltaic eluphahleni.
