Lokhu kuvumelana nezimo kunciphisa ukutshalwa kwezimali kwangaphambili kuyilapho kugcinwa izinketho zokukhula zesikhathi esizayo.
imibuzo ejwayelekile ukubuzwa
Ingabe amaphaneli elanga angakwazi ukunika amandla ikhaya lami ngesikhathi sokucima kukagesi ngaphandle kwamabhethri?
Cha. Amaphaneli elanga angenawo amabhethri awanikezi amandla phakathi nokucisha kwegridi, ngisho nezinsuku libalele, ngoba imithetho yezokuphepha idinga ukuthi avale ukuze avimbele{1}}ukuphakela ugesi ongalimaza izisebenzi. Amasistimu okugcina ilanga namandla elanga kuphela angasuka kugridi futhi aqhubeke nokunikeza amandla.
Amandla elanga agciniwe ahlala isikhathi esingakanani kumabhethri?
Amandla elanga agcinwe kumabhethri e-lithium{0}}e-ion ngokuvamile ahlala esebenza izinsuku ezingu-1-5, kuye ngomthamo wesistimu, ukusebenza kahle, kanye nezidingo zokusetshenziswa. Wonke amabhethri athola-ukuzikhulula{5}}i-lithium-ion ilahleka cishe ngo-1-3% nyanga zonke. Ngezinjongo ezingokoqobo, isitoreji senzelwe ukuhamba ngebhayisikili nsuku zonke esikhundleni sokubamba isizini.
Ingabe ukungeza isitoreji kusistimu yami sonozungezilanga ekhona kakade kuzosebenza?
Ukufakwa okuningi okukhona kwelanga kungathuthukiswa ngokugcinwa kwebhethri, nakuba ukuhlolwa kokuhambisana ochwepheshe kuqinisekisa ukuhlanganisa okungenazihibe. Amasistimu esitoreji selanga namandla asebenza kahle kakhulu uma aklanywe ndawonye, kodwa amabhethri e-AC-ahlangene angena kabusha kalula kunamasistimu ahlanganisiwe e-DC{2}}. Kodwa-ke, ama-inverter amadala angase angabi namandla okuxhumana nebhethri, okungenzeka adinge ukushintshwa.
Yikuphi ukunakekelwa okudingwa amabhethri elanga?
Amabhethri e-Lithium-ion ayalungiswa-amahhala, kuyilapho amabhethri e-lead{2}}e-asidi edinga ukuchelelwa kanye nokuhlolwa kwe-valve. Amasistimu adinga ukuhlolwa ngezikhathi ezithile{4}}ukuhlola ukuxhumana, ukuqapha amamethrikhi okusebenza, kanye nokuqinisekisa ukuthi amasistimu okupholisa asebenza kahle. Abakhiqizi abaningi batusa ukuhlolwa kochwepheshe kwaminyaka yonke, nakuba isofthiwe yokuqapha ixwayisa abanikazi ngezinkinga zokusebenza ngokuzenzakalelayo.
I-Strategic Value Equation
Umnotho wesitoreji elanga udlulela ngale kwezibalo ezilula zokubuyisela emuva. Izinzuzo eziningana ziphikisana nokulinganisa kodwa ziqhuba izinqumo zokutholwa.
Ukuvikeleka kwamandla ngesikhathi sokwehluleka kwegridi kuzuze ukuvelela njengoba{0}}ukucima okuhlobene nesimo sezulu kwanda. Umsebenzisi oyedwa we-Reddit uchaze ukuthi ukuphela kwendlu enamandla ngesikhathi kucima ugesi endaweni, eqhubeka nemisebenzi evamile kuyilapho omakhelwane behleli ebumnyameni. Leli nani lokwethenjelwa likhuphuka kakhulu kubasebenzisi bemishini yezokwelapha, amabhizinisi asekhaya, noma izifunda ezinenkinga yokucima njalo.
Ukuthuthukiswa kwesakhiwo sesilinganiso kunikeza inani eliqhubekayo. Izinsiza ziya ngokuya zisebenzisa isikhathi-sokuthi{2}}intengo yokusetshenziswa, izinkokhiso zokufunwa, kanye nemikhawulo yokuthekelisa enciphisa umnotho ozimele welanga. Isitoreji siguqula ukukhiqizwa kwe-solar okungaguquki kube ukusetshenziswa okuvumelana nezimo, okuthatha inani ngokusebenzisa isikhathi esibalulekile esikhundleni sevolumu yokukhiqiza.
Ukwehliswa kwe-Carbon footprint kuyaqina lapho isitoreji sisusa ukuncika kwegridi yakusihlwa. Ugesi wegridi utholakala ikakhulukazi kumafutha ezinto ezimbiwa phansi, ngakho ukudweba amandla ebusuku kubukela phansi izinzuzo zemvelo zelanga. Isitoreji sinika amandla ukusebenza okuvuselelekayo okungu-24/7, okukhulisa umthelela wesimo sezulu.
Iminikelo yokusimama kwegridi ibalulekile esikalini somphakathi. Isitoreji esisabalalisiwe esihlanganiswe ezimbonini zamandla abonakalayo sinikeza opharetha begridi umthamo oguquguqukayo onciphisa ukuthembela ezitshalweni ze-fossil peaker. Abahlanganyeli bathola isinxephezelo kuyilapho besekela ukuhlanganiswa okunabile okuvuselelekayo.
Ukuqonda okuyisisekelo: amasistimu elanga namandla okugcina amandla aguqula ilanga lisuka emthonjeni wokukhiqiza ngezikhathi ezithile libe yimpahla yamandla ethunyelwayo. Lolu shintsho lushintsha kokubili umnotho ngamunye kanye nesakhiwo segridi, lusheshisa ushintsho oluvuselelekayo kuyilapho luhlinzeka ngezinzuzo ezibonakalayo zasendlini. Ukuthi utshalomali lunengqondo yini kuncike ezindlekweni zakho zikagesi, ukuvama kokucisha, izinxephezelo ezitholakalayo, kanye nenani elibekwe ekuzimeleni kwamandla{2}kodwa ubuchwepheshe bukhulile kusukela kokuhlolwa kuya kokusebenziseka ngesabelo esikhulayo sokufakwa.
