Lithini ixabiso lebhetri yelanga yasekhaya ngekWh nganye?Ngaba ufuna i-backup yebhetri yendawo yokuhlala kwinkqubo yakho ye-photovoltaic?Apha uya kufumana iimpendulo. Iindleko zokusetyenziswa kwebhetri yelanga ekhaya ziyahluka ngokubanzi, kuxhomekeke kakhulu kwiinkampani yebhetri yelanga.Ngaphambili, sasisebenzisa iibhetri ze-lead-acid ukugcina amandla elanga.Ngelixa ubugcisa beebhetri ze-lead-asidi bukhulile ngokwentelekiso, ixabiso elilindelekileyo nge-kilowatt ngeyure nganye linokuba yi-$500 ukuya kwi-1,000 yeedola! Iibhetri zelanga zeLithium-ion zithatha ngokuthe ngcembe iibhetri ze-lead-acid njengesizukulwana esilandelayo seenkqubo zokugcina ibhetri yasekhaya ngenxa yokusebenza kwazo okuphezulu, umthamo okhoyo kunye nobomi benkonzo obude, kodwa nazo ziza neendleko eziphezulu zokuthenga, ngoko iindleko ezilindelekileyo kWh yeebhetri zelanga zasekhaya ze-lithium-ion yi-$800 ukuya kwi-1,350 yeedola. 
Ngaba iibhetri zelanga zasekhaya zinexabiso? Iiphotovoltaics zivelisa umbane ukusuka ekukhanyeni kwelanga.Ngako oko, inkqubo ye-photovoltaic inokuvelisa kuphela amandla amaninzi xa ilanga likhanya.Oku kusebenza ngokukodwa kwixesha ukusuka kusasa ukuya emva kwemini.Ukongeza, unesona sivuno sikhulu sombane entwasahlobo, ehlotyeni nasekwindla.Ngelishwa, la ikwangamaxesha apho ikhaya lakho lifuna umbane omncinci.Ukusetyenziswa kombane kuphezulu ngeeyure zangokuhlwa nangeenyanga ezimnyama zasebusika.Ngoko, isishwankathelo, oku kuthetha: ● Isixokelelwano sinikezela ngombane omncinane kakhulu kanye xa uwufuna. ●Kwelinye icala, umbane omninzi kakhulu uveliswa ngexesha ngeyona mfuno iphantsi. Ke ngoko, uwiso-mthetho udale ithuba lokondla amandla elanga ongayidingi kwigridi yoluntu.Ufumana umrhumo wokuziswa koku.Nangona kunjalo, kufuneka uthenge umbane wakho kubaboneleli bamandla oluntu ngamaxesha emfuno ephezulu.Isisombululo esifanelekileyo sokukwazi ukusebenzisa ngokufanelekileyo umbane ngokwakho yinkqubo yokugcina ibhetri yenkqubo yakho ye-photovoltaic.Oku kukuvumela ukuba ugcine okwethutyana umbane ogqithisileyo de ube uwufuna. Ngaba ndiyayidinga inkqubo yebhetri yelanga yasekhaya kwi-photovoltaic system yam? Hayi, i-photovoltaics iphinda isebenze ngaphandle kokugcinwa kwebhetri.Nangona kunjalo, kule meko uya kuphulukana nombane ogqithileyo kwiiyure ezinemveliso ephezulu ukuze uwusebenzise.Ukongeza, kufuneka uthenge umbane kwigridi kawonke-wonke ngamaxesha afunwa kakhulu.Uhlawulwa ngombane owufaka kwigridi, kodwa emva koko uchithe imali ekuthengeni kwakho.Ungade uyihlawule ngakumbi kunomvuzo wakho ngokuyondla kwigridi. Ukongeza, umvuzo wakho ovela kumrhumo we-feed-in usekwe kwimimiselo yomthetho, enokutshintsha okanye irhoxiswe ngokupheleleyo nangaliphi na ixesha.Ukongeza, umrhumo we-feed-in uhlawulwa kuphela isithuba seminyaka engama-20.Emva koko, kuya kufuneka uthengise umbane wakho ngokwakho ngee-broker.Ixabiso lemarike lamandla elanga okwangoku limalunga neesenti ezi-3 kuphela ngeyure yekilowatt. Ke ngoko, kuya kufuneka uzame ukusebenzisa amandla akho elanga kangangoko unakho kwaye ke ngoko uthenge kancinci kangangoko.Unokufezekisa oku kuphela ngenkqubo yokugcina ibhetri yekhaya ehambelana ne-photovoltaics yakho kunye neemfuno zakho zombane. Lithetha ukuthini inani le-kWh ngokunxulumene nokugcinwa kwebhetri yelanga yasekhaya? Iyure yekilowathi (kWh) yiyunithi yomlinganiselo womsebenzi wombane.Ibonisa ukuba isixhobo sombane sivelisa amandla angakanani (ijenereyitha) okanye sisebenzisa (umsebenzisi wombane) ngeyure enye.Yiba nomfanekiso weglowubhu enamandla e-100 watts (W) ivutha iiyure ezili-10.Emva koko oku kubangela ukuba: 100 W * 10 h = 1000 Wh okanye 1 kWh. Kwiinkqubo zokugcina ibhetri yasekhaya, eli nani likuxelela ukuba ungakanani amandla ombane onokuwagcina.Ukuba loo nkqubo yogcino lwebhetri yasekhaya icaciswe njengekhilowathi yeyure e-1, ungasebenzisa amandla agciniweyo ukugcina ibhalbhu yesibane ekhankanywe ngasentla ye-100-watt ivutha iiyure ezili-10 ezipheleleyo.Kodwa isiseko sesokuba indawo yokugcina ibhetri yelanga yasekhaya kufuneka ihlawulwe ngokupheleleyo! Ingaba inkqubo yogcino lwebhetri yekhaya inexabiso? Njengoko izifundo zibonisile, ungasebenzisa kuphela i-30% yombane owenziwe yi-photovoltaic system yakho ngokwakho.Ngokusetyenziswa kwe-aibhanki yebhetri yasekhaya yelanga, eli xabiso linyuka ukuya kwi-70% - 80%.Ukuze ube nengeniso, iyure yekilowatt ukusuka kwindawo yakho yokugcina ibhetri yelanga akufuneki ibize ngaphezulu kweyure yekilowatt ethengwe kwigridi yoluntu. Inkqubo ye-Photovoltaic ngaphandle kwebhanki yebhetri yasekhaya yelanga Ukumisela i-amortization yenkqubo ye-photovoltaic ngaphandle kwebhanki yebhetri yasekhaya yelanga, sisebenzisa le mizekelo ilandelayo yamaxabiso: ● Iindleko zeemodyuli zelanga kunye ne-5 kilowatt peak (kWp) imveliso: i-7500 yeedola. ● Iindleko ezongezelelweyo (umzekelo uxhulumaniso lwenkqubo): 800 dollar. ● Iindleko zizonke zokuthenga: i-8300 yeedola Iimodyuli zeSolar ezinesiphumo esipheleleyo se-1 kilowatt peak zenza malunga neeyure ezingama-950 ze-kilowatt ngonyaka.Ngaloo ndlela, isivuno esipheleleyo senkqubo yi-5 kilowatt peak (5 * 950 kWh = 4,750 kWh ngonyaka).Oku kuphantse kulingane neemfuno zombane zonyaka zosapho lwe-4. Njengoko sele kukhankanyiwe, ungasebenzisa kuphela malunga ne-30 % okanye i-1,425 kilowatt iiyure ngokwakho.Awunyanzelekanga ukuba uthenge esi sixa sombane kuncedo lukawonke-wonke.Ngexabiso leesenti ezingama-30 ngeyure yekilowatt, ugcina i-427.5 yeedola kwiindleko zombane zonyaka (1,425 * 0.3). Ngaphezulu koko, ufumana i-3,325 kilowatt-iiyure ngokondla umbane kwigridi (4,750 - 1,425).Uluhlu lwamaxabiso ngoku luhla qho ngenyanga ngepesenti ye-0.4 ekhulwini.Kwisithuba senkxaso-mali yeminyaka engama-20, umrhumo wokutsalela umrhumo wenyanga apho umzi-mveliso wabhaliswa waze wamiselwa ngawo uyasebenza.Ekuqaleni kuka-2021, ixabiso lokutya lalimalunga neesenti ezili-9 ngekilowatt ngeyure. Oku kuthetha ukuba umrhumo we-feed-in uphumela kwinzuzo ye-299.25 dollar (3,325 kWh * 0.09 euros). Itotali yokonga kwiindleko zombane yi-726.75 yeedola.Ngoko ke, utyalo-mali kumzi-mveliso luya kuzihlawulela ngokwalo kwiminyaka emalunga ne-11.Nangona kunjalo, oku akuthatheli ngqalelo iindleko zonyaka zokugcinwa kwenkqubo ye-approx.108.53 euro. Inkqubo ye-Photovoltaic kunye nokugcinwa kwebhetri yelanga yasekhaya Sithatha idatha yesityalo esifanayo njengoko kuchazwe kwindawo yangaphambili.Umgaqo wesithupha uthi ibhanki yebhethri ye-lithium ion yelanga kufuneka ibe nomthamo ofanayo wokugcina amandla enkqubo ye-photovoltaic.Ngaloo ndlela, inkqubo yethu ene-5 kilowatts peak ibandakanya i-backup yebhetri yelanga yekhaya kunye nomthamo we-5 kilowatts peak.Ngokwexabiso eliqhelekileyo le-800 yeedola nge-kilowatt-yure yendawo yokugcina ekhankanywe ngasentla, iyunithi yokugcina ixabisa i-4000 yeedola.Ixabiso lesityalo ngaloo ndlela landa kwi-dollar ye-12300 (8300 + 4000). Kumzekelo wethu, njengoko sele kukhankanyiwe, isityalo sivelisa i-4,750 kilowatt-iiyure ngonyaka.Nangona kunjalo, ngoncedo lwetanki yokugcina, ukuzisebenzisa ngokwakho kwandisa ukuya kwi-80% yobuninzi bombane owenziweyo okanye i-3800 kilowatt-yure (4,750 * 0.8).Ekubeni akufuneki uthenge le mali yombane kwinkonzo yoluntu, ngoku ugcina i-1140 yeedola kwiindleko zombane ngexabiso lombane leesenti ezingama-30 (3800 * 0.3). Ngokutyisa ama-950 eekilowatt-iiyure eziseleyo (4,750 – 3800 kWh) kwigridi, ufumana i-85.5 yeedola ezongezelelweyo ngonyaka (950 * 0.09) kunye nentlawulo ekhankanywe ngasentla yeesenti ezisi-8.Oku kubangela ukongiwa konyaka kwiindleko zombane ze-1225.5 yeedola.Iplanti kunye nenkqubo yokugcina iya kuzihlawulela ngokwazo kwisithuba esimalunga ne-10 ukuya kwi-11 leminyaka.Kwakhona, asikhange sizithathele ngqalelo iindleko zonyaka zokulungisa. Yintoni endifanele ndinikele ingqalelo kuyo xa ndithenga kwaye ndisebenzisa iibhetri zelanga zasekhaya? Ngenxa yokusebenza kakuhle kunye nobomi obude kuneebhetri ezikhokelayo, kufuneka uthenge indawo yokugcina ibhetri yekhaya kunye neebhetri ze-lithium-ion.Qinisekisa ukuba ibhetri yelanga yasekhaya inokumelana nemijikelo yokutshaja emalunga ne-6,000 kwaye ufumane unikezelo kubaboneleli abaninzi.Kukwakho umahluko omkhulu wamaxabiso kwiinkqubo zale mihla zokugcina iibhetri. Kuya kufuneka kwakhona ufake ibhanki yebhetri yelanga yasekhaya kwindawo epholileyo ngaphakathi endlwini.Amaqondo obushushu angaphaya kwama-30 ngokukaCelsius kufuneka aphetshwe.Izixhobo azifanelekanga ukufakwa ngaphandle kwesakhiwo.Kufuneka kwakhona ukhuphe iiibhetri zelanga ze-lithium ionrhoqo.Ukuba bahlala bephantsi kolawulo olupheleleyo ixesha elide, oku kuya kuba nefuthe elibi kubomi babo. Ukuba ulandela le miyalelo, ibhanki yebhetri yelanga yasekhaya iya kuhlala ixesha elide kunewaranti yeminyaka eyi-10 edla ngokunikwa ngabavelisi.Ngokusetyenziswa okufanelekileyo, iminyaka eyi-15 nangaphezulu inokwenyani.
