U-Ann Arbor (ukuphawula ngokwaziswa) – Umthetho Wokuncishiswa Kwamandla Emali (i-IRA) ususungule ikhredithi yentela engu-30% yeminyaka eyi-10 yokufaka ama-solar ophahleni lwezindlu.Uma othile ehlela ukuchitha isikhathi eside endlini yakhe.I-IRA ayigcini ngokuxhasa iqembu ngokwalo ngamakhefu amakhulu entela.
NgokoMnyango Wezamandla, u-Toby Stranger ku-Consumer Reports ubala izindleko ezilandelayo ongathola ngazo ikhredithi yentela engu-30% yesistimu yakho yelanga lasekhaya.
Ukuphila okuwusizo kwephaneli yelanga cishe iminyaka engama-25.Ngaphambi kokufaka ngo-2013, sayifulela kabusha indlu futhi sithemba ukuthi amathayela amasha azohlala isikhathi eside njengamaphaneli amasha.Amaphaneli ethu angu-16 elanga abiza u-$18,000 futhi akhiqiza amahora angaphezu kwama-megawatt angu-4 ngonyaka.U-Ann Arbor unokukhanya kwelanga okuncane kakhulu ngoDisemba nangoJanuwari, ngakho lezo zinyanga ezimbili ziyimfucuza.Kodwa-ke, lawa maphaneli acishe amboze ngokuphelele ukusetshenziswa kwethu kwasehlobo, futhi njengoba i-air conditioner yethu ingugesi, yilokho esikufunayo.
Uzozwa izinto eziningi, eziningi zazo ezingalungile, mayelana nokuthi kufanele ukhokhe isikhathi esingakanani ukuze wonge ugesi.Uhlu lwamaphaneli esinawo namuhla lungabiza noma yikuphi ukusuka ku-$12,000 kuya ku-$14,000 ngoba izindleko zamaphaneli zehle kakhulu.Nge-IRA, ungathola isikweletu sentela esingu-30%, ucabanga ukuthi ukweleta leyo mali yentela.Kuhlelo lwama- $ 14,000, lokhu kwehlisa izindleko ku-$9,800.Kodwa cabanga ngalokhu: UZillow ulinganisela ukuthi amaphaneli elanga angenza ikhaya lakho libe likhulu ngo-4%.Ekhaya lika-$200,000, inani lokulingana likhuphuka ngo-$8,000.
Kodwa-ke, njengoba intengo yekhaya elimaphakathi e-US kulo nyaka ingu-$348,000, ukufaka amaphaneli elanga ophahleni kungangeza u-$13,920 enanini lakho.Ngakho-ke phakathi kwekhefu lentela kanye nenzuzo yemali enkulu, amaphaneli cishe akhululekile ukusebenzisa, kuye ngama-kilowatts wamalungu afanayo owafakayo.Uma ubheka isikweletu sentela futhi ukhuphuka inani lasekhaya, ungagcina imali yakho yamandla, uma kungenjalo ngokushesha, khona-ke ngemva nje kokuyithenga.Yiqiniso, ukukhuphuka kokulingana akubalulekile kuze kube yilapho iphaneli ifinyelela ekupheleni kwempilo yayo, ngakho akuwona wonke umuntu ozimisele ukuthembela kuyo.
Ngisho ngaphandle kokukhuphuka kokulingana, ezweni lami uhlelo lwe-$ 14,000 lungathatha iminyaka engaphezu kwengu-7 ukukhokha ngemuva kwekhredithi yentela, engeningi ohlelweni lweminyaka engama-25.Ngaphezu kwalokho, njengoba izindleko zamafutha ezinsalela zikhuphuka, isikhathi sokukhokha siyaba mfishane.E-UK, amaphaneli elanga alinganiselwa ukuthi azokhokha esikhathini esingangeminyaka emine ngenxa yokukhuphuka kwamanani kaphethiloli wezinsalela.
Uma uhlanganisa amaphaneli elanga nesistimu yebhethri yasekhaya efana ne-Powerwall, isikhathi sokukhokha singanqanyulwa phakathi.Futhi njengoba kushiwo ngenhla, kukhona nezinxephezelo zentela ezitholakalayo uma uthenga le mikhiqizo.
Futhi, uma uthenga imoto kagesi, ungathola ikhredithi yentela engu-$7,500 kwezinye izimo, futhi usebenzisa ishaja esheshayo emini ukushaja imoto yakho ngamaphaneli elanga, noma usebenzisa ibhethri lasekhaya njenge-Powerwall.Isistimu ekhokhela isikhathi esincane samahhala kokubili emshinini nasephaneli, ukonga kugesi nogesi.
Uma ngikhuluma iqiniso, kimi kubonakala sengathi uma ungumnikazi wendlu futhi uhlala emzini wakho wamanje eminye iminyaka eyishumi, cishe uchitha imali ngokungawafaki ama-solar panel.
Ngaphandle kwezindleko, wanelisekile ngokuncipha kokukhishwa kwe-CO2.Amaphaneli ethu akhiqize ama-33.5 MWh wokukhanya kwelanga, okuthi, uma akwanele, anciphise kakhulu ukukhiqizwa kwethu kwekhabhoni.Asicabangi ukuthi sizoba kule ndlu isikhathi eside, noma sizofaka amaphaneli engeziwe futhi sifake iphampu yokushisa, futhi manje imali enkulu yentela.
