Iphrojekthi yokukhiqiza amandla yasekhaya ye-photovoltaic iqinisekiswa yinkampani yegridi ngokusetshenziswa okuxhunywe kugridi. Ngakho-ke kungenzeka kanjani ukuhlomisa iphrojekthi yezinhlelo ze-photovoltaic zasekhaya nge-ibhange lamandla lasekhaya? Izindleko zingabuyiswa iminyaka emingaki? Futhi siyini isimo samanje sokusetshenziswa komhlaba wonke? Kulesi sihloko, sizoxoxa ngokuhlaziywa kokungenzeka kwamandla wekhaya we-photovoltaic we-solar system wamanje kusuka ezimweni ezintathu. Kwezinye izindawo ezithuthukisiwe, izindleko zokusetshenziswa kukagesi ziphakeme uma kuqhathaniswa, kanti izinsiza zegridi zizonke azizinzile futhi zithembekile. Ngakho-ke, ukwehlisa izindleko zikagesi eziphelele yikona okuhamba phambili ekufakeni amandla asekhaya. Ngokombono wokusetshenziswa kukagesi ngomuntu ngamunye, ukusetshenziswa kukagesi kwe-Germany/USA/Japan/Australia kuzoba ngu-7,035/12,994/7,820/10,071 kWh ngo-2021, okuyizikhathi ezingu-1.8/3.3/1.99/2.56 ze-China ngayinye ukusetshenziswa kukagesi (3,927kWh) ngesikhathi esifanayo. Ngokombono wamanani kagesi, amanani kagesi wendawo yokuhlala ezindaweni ezithuthukile emhlabeni wonke nawo aphezulu kakhulu. Ngokwezibalo ezivela ku-Global Petrol Prices, isilinganiso senani likagesi wendawo yokuhlala e-Germany/United States/Japan/Australia ngoJuni 2020 ngu-36/14/26/26/34 cents/kWh, okuyizikhathi ezingu-4.2/1.65/3.1/4 zendawo yokuhlala yase-China. intengo kagesi (amasenti angu-8.5) ngesikhathi esifanayo. Icala 1:Australia Residential solar home power systems Isikweletu sikagesi esimaphakathi sase-Australia sinokuhlukahluka okuningi, kuye ngosayizi wekhaya lakho kanye nenani lezinto zikagesi ozisebenzisa nsuku zonke. Nokho, isilinganiso sokusetshenziswa kukagesi ezweni lonke e-Australia singama-9,044 kWh ngonyaka noma 14 kWh ngosuku. Ngeshwa, eminyakeni emithathu edlule, izikweletu zikagesi wasendlini zikhuphuke ngaphezu kwama-$550. Izinto zikagesi zasendlini namandla akhonjisiwe kuleli thebula elilandelayo:

Isilinganiso sanyanga zonke esisetshenziswa ugesi kulo muzi e-Australia silinganiselwa ku-650 kWh, kanti isilinganiso sikagesi esisetshenziswa minyaka yonke singama-7,800 kWh ngenyanga. Ngokombiko wentengo kagesi wenkambiso ye-Australian Energy Market Council, isilinganiso sesikweletu sikagesi saminyaka yonke sase-Australia kulo nyaka sikhuphuke ngo-$100 ngonyaka odlule, safinyelela ku-$1,776, kanti isilinganiso sesikweletu sikagesi nge-kilowatt-hora singamasenti angu-34.41: Kubalwa ngama-kilowatt-amahora angu-7,800 kagesi ngonyaka: Inkokhelo kagesi yonyaka=$0.3441*7800kWh=$2683.98 Vala Isixazululo Sezinhlelo Zamandla Wasekhaya Wegridi Ngokwesimo sendlu, siklame isisombululo sebhethri yamandla elanga esisodwa. Idizayini isebenzisa amamojula angu-12 500W, isamba samamojula angu-6kW, futhi ifaka ama-inverter okugcina amandla aqondiswa kabili ama-5kW, angaphehla ugesi ongu-580~600kWh ngenyanga ngokwesilinganiso. Amandla e-Photovoltaic angasetshenziswa ingxenye yesikhathi, kanye ne-BSLBATT7.5kWh isitoreji samandla ebhethri ye-lithiumilungiswa ngokuya kwesikhathi sokusetshenziswa kwamandla okuphezulu kwamahora angu-6, esisetshenziselwa ukulayisha amandla okusetshenziswa ngezikhathi eziphakeme ngaphandle kokukhanya kwelanga. Amandla elanga lasekhaya ewonke angahlangabezana nesidingo samakhasimende sikagesi. 
Ukuhlaziywa kwenzuzo yezomnotho: Njengamanje, izindleko zezinhlelo ze-photovoltaic zingu-$0.6519/W, futhi izindleko zamabhethri okugcina amandla aphansi zingaba ngu-$0.2794/Wh. Utshalomali lwesitoreji samandla esingu-5kW + BSLBATT 7.5kWh ibhethri le-Powerwall cishe lingama-$6000, futhi izindleko eziyinhloko zimi kanje:

Isitolo sitholakala eTexas, ngesilinganiso sanyanga zonke sokusetshenziswa kwamandla okungaba ngu-1400 kWh. Intengo kagesi wentengiso kule ndawo ingu-7.56 cents/kWh: 
Ngokwezibalo, isikweletu sikagesi sanyanga zonke somthengisi oshintshile=$0.0765*1400kWh=$105.84 Vala Isixazululo Sezinhlelo Zamandla Wasekhaya Wegridi Ngokwesimo somsebenzisi, uhlelo lwamukela isisombululo sebhethri lesigaba sesithathu. Lolu hlelo luklanyelwe ukusebenzisa amamojula angu-24 500W, isamba samamojula angu-12kW, kanye ne-inverter yokugcina amandla engu-10kW yezindlela ezimbili, engakhiqiza amahora angu-1,200 kilowatt kagesi ngenyanga ngokwesilinganiso, ehlangabezana nezidingo zikagesi zekhasimende. Ngokusho kokusebenza kwesitolo samakhekhe, umthwalo omningi ugxile esikhathini sokusebenzisa amandla aphezulu emini, kanti umthwalo mncane ebusuku. Ngakho-ke, amandla e-photovoltaic angasetshenziswa ngokuyinhloko ngesikhathi sokusetshenziswa kwamandla aphezulu, ahlanganiswe nebhethri yasekhaya yelanga kanye negridi; ingasetshenziswa ikakhulukazi ebusuku amandla ebhethri anamandla elanga, amandla egridi njengesengezo; ngakho-ke, indawo yokugcina amandla yasekhaya ifakwe i-BSLBATT 15kWh
