Izindaba zakamuva emkhakheni wokugcinwa kwamandla ekhaya zigxile ezindlekweni ze-powerwall.Ngemuva kokwenyusa intengo kusukela ngo-Okthoba 2020, uTesla usanda kukhulisa intengo yomkhiqizo wakhe odumile wokugcina ibhethri lasekhaya, i-Powerwall, yaya ku- $ 7,500, okwesibili ezinyangeni ezimbalwa nje lapho uTesla enyuse intengo yawo.Lokhu kuphinde kwashiya abasebenzisi abaningi bedidekile futhi bengakhululekile.Nakuba inketho yokuthenga isitoreji samandla sasekhaya isikhona iminyaka eminingi, intengo yamabhethri omjikelezo ojulile nezinye izingxenye ezidingekayo ibe phezulu, imishini inkulu futhi idinga izinga elithile lolwazi ukuze lisebenze futhi ligcinwe.Lokhu kusho ukuthi kuze kube manje ukugcinwa kwamandla okuhlala kukhawulelwe kakhulu ezinhlelweni ezingaphandle kwegridi kanye nabashisekeli bokugcina amandla.Izintengo ezehla ngokushesha kanye nentuthuko yamabhethri e-lithium-ion nobuchwepheshe obuhlobene kushintsha konke lokhu.Isizukulwane esisha semishini yokugcina ilanga ishibhile, sibiza kakhulu, sihlelekile futhi siyajabulisa ngobuhle.Ngakho-ke ngo-2015, u-Tesla wanquma ukusebenzisa ubuchwepheshe bakhe ngokwethula i-Powerwall ne-Powerpack ukwenza amaphakethe ebhethri ezimoto zikagesi futhi akhiqize imishini yokugcina amandla ezosetshenziswa ezindlini nasemabhizinisini.Umkhiqizo wokugcina amandla we-Powerwall usudume kakhulu kumakhasimende anamandla elanga amakhaya awo futhi afuna ukuba namandla okwenza ikhophi yasenqolobaneni, futhi usudume kakhulu kumaphrojekthi wakamuva wokutshala amandla abonakalayo.Futhi muva nje, ngokwethulwa kwezikhuthazo zokugcinwa kwebhethri lasekhaya e-US, kube nzima kumakhasimende ukuthola i-Tesla Powerwall njengoba isidingo sokugcinwa kwamandla sikhula.Ngo-Ephreli odlule, uTesla umemezele ukuthi ufake amaphakethe ebhethri esitoreji sasekhaya se-Powerwall ayi-100,000.Ngaso leso sikhathi, i-CEO u-Elon Musk uthe uTesla usebenzela ukukhulisa ukukhiqizwa kwe-Powerwall ngenxa yokwanda kokubambezeleka kokulethwa ezimakethe eziningi.Kungenxa yokuthi isidingo sesinesikhathi eside sidlula ukukhiqizwa okwenza uTesla enyusa inani le-Powerwall.Izinto ozikhethayoUma ucubungula izinketho ze-solar + zokugcina, uzohlangabezana nemininingwane eminingi eyinkimbinkimbi yomkhiqizo eyenza izindleko zibe nzima.Kumthengi, amapharamitha abaluleke kakhulu ngesikhathi sokuhlola, ngaphandle kwezindleko, umthamo namandla webhethri isilinganiso, ukujula kokukhipha (i-DoD), ukusebenza kahle kokuya nokubuya, iwaranti nomkhiqizi.Lezi yizinto ezibalulekile ezithinta izindleko zesikhathi zokusetshenziswa kwesikhathi eside.1. Amandla namandlaAmandla yisamba senani likagesi iseli lelanga elingagcina, likalwa ngama-kilowatt amahora (kWh).Amaseli elanga amaningi asekhaya aklanyelwe ukuthi 'abekeke', okusho ukuthi ungafaka amaseli amaningi kusistimu ye-solar kanye nesitoreji ukuze uthole umthamo owengeziwe.Amandla akutshela umthamo webhethri, kodwa hhayi ukuthi angaletha amandla angakanani ngesikhathi esithile.Ukuze uthole isithombe esigcwele, udinga futhi ukucabangela isilinganiso samandla ebhethri.Kumaseli elanga, isilinganiso samandla yinani likagesi iseli elingalethwa ngesikhathi esisodwa.Ikalwa ngama-kilowatts (kW).Amaseli anomthamo omkhulu kanye nesilinganiso samandla aphansi azoletha amandla amancane isikhathi eside (anele ukusebenzisa imishini ethile ebalulekile).Amabhethri anomthamo ophansi kanye nezilinganiso zamandla aphezulu azogcina ikhaya lakho lonke lisebenza, kodwa amahora ambalwa kuphela.2. Ukujula kokukhishwa (DoD)Ngenxa yokwakheka kwawo kwamakhemikhali, amaseli elanga amaningi adinga ukugcina imali ethile ngaso sonke isikhathi.Uma usebenzisa u-100% wokushajwa kwebhethri, ubude bayo bempilo buzoncishiswa kakhulu.Ukujula kokukhipha (i-DoD) kwebhethri umthamo webhethri osetshenzisiwe.Abakhiqizi abaningi bazocacisa i-DoD ephezulu yokusebenza kahle.Isibonelo, uma ibhethri elingu-10 kWh line-DoD engu-90%, ungasebenzisi ngaphezu kuka-9 kWh ngaphambi kokushaja.Ngokuvamile, i-DoD ephakeme isho ukuthi uzokwazi ukusebenzisa umthamo webhethri owengeziwe.3. Ukusebenza kahle kohambo lokuya nokubuyaUkusebenza kahle kokuya nokubuya kwebhethri kumelela inani lamandla angasetshenziswa njengephesenti lamandla alo agciniwe.Isibonelo, uma amandla angu-5 kWh efakwa ebhethrini futhi kutholakala kuphela u-4 kWh wamandla awusizo, ukusebenza kahle kwebhethri kokuya nokubuya kungu-80% (4 kWh / 5 kWh = 80%).Ngokuvamile, ukusebenza kahle okuphezulu kohambo lokuya nokubuya kusho ukuthi uzothola inani elithe xaxa lezomnotho ebhethrini.4. Impilo yebhethriNgokusetshenziswa okuningi kwesitoreji sasekhaya samandla, amabhethri akho "azoshayelwa ibhayisikili" (ashajwe futhi akhishwe) nsuku zonke.Uma ibhethri lisetshenziswa kakhulu, amandla ayo okubamba ibhethri aye ehla kakhulu.Ngale ndlela, amaseli elanga afana nebhethri kumakhalekhukhwini wakho - ushaja ifoni yakho njalo ebusuku ukuze uyisebenzise phakathi nosuku, futhi njengoba ifoni yakho ikhula uqala ukuqaphela ukuthi ibhethri liyaphela.Uhla olujwayelekile lwempilo yeseli yelanga yiminyaka emi-5 kuye kweyi-15.Uma amaseli elanga efakwe namuhla, cishe angadinga ukushintshwa okungenani kanye ukuze afane neminyaka engama-25 kuya kwengama-30 yokuphila kwesistimu ye-PV.Kodwa-ke, njengoba nje isikhathi sokuphila samaphaneli elanga senyuke kakhulu kule minyaka eyishumi edlule, amaseli elanga kulindeleke ukuthi alandele njengoba imakethe yezixazululo zokugcina amandla ikhula.5. IsondloUkugcinwa okufanele nakho kungaba nomthelela omkhulu empilweni yamaseli elanga.Amangqamuzana elanga athinteka kakhulu izinga lokushisa, ngakho ukuwavikela emazingeni okushisa aqandayo noma ashisayo kuzokwandisa ukuphila kwamaseli.Uma i-PV cell yehla ngaphansi kuka-30°F, izodinga amandla kagesi engeziwe ukuze ifinyelele amandla amakhulu.Uma iseli elifanayo likhuphuka ngaphezu komkhawulo ongu-90°F, lizoshisisa kakhulu futhi lidinga ukushajwa okuncane.Ukuze kuxazululwe le nkinga, abakhiqizi abaningi bebhethri abahamba phambili, abanjengoTesla, banikeza ukulawulwa kwezinga lokushisa.Kodwa-ke, uma uthenga iseli elingenalo, uzodinga ukucabangela ezinye izixazululo, njengendawo ebiyelwe enesisekelo.Umsebenzi wokugcinwa kwekhwalithi ngokungangabazeki uzothinta isikhathi sokuphila kweseli yelanga.Njengoba ukusebenza kwebhethri kuzokwehla ngokwemvelo ngokuhamba kwesikhathi, abakhiqizi abaningi bazophinde baqinisekise ukuthi ibhethri izogcina umthamo othile ngesikhathi sewaranti.Ngakho-ke, impendulo elula yombuzo othi "Iseli lami lelanga lizohlala isikhathi esingakanani?"Lokhu kuncike kuhlobo lwebhethri olithengayo nokuthi mangakanani amandla azolahleka ngokuhamba kwesikhathi.6. AbakhiqiziIzinhlobo eziningi ezahlukene zezinhlangano zakha futhi zenza imikhiqizo ye-solar cell, kusukela ezinkampanini zezimoto kuya ekuqaleni kobuchwepheshe.Inkampani enkulu yezimoto engena emakethe yokugcina amandla ingase ibe nomlando omude wemikhiqizo yokukhiqiza, kodwa ingase inganikezi ubuchwepheshe obushintsha kakhulu.Ngokuphambene, ukuqaliswa kobuchwepheshe kungase kube nobuchwepheshe obusha bokusebenza okuphezulu kodwa hhayi irekhodi eliqinisekisiwe lomsebenzi webhethri wesikhathi eside.Ukuthi ukhetha ibhethri elenziwe yisiqalo noma umkhiqizi osenesikhathi eside ukhona kuncike ezintweni eziza kuqala kuwe.Ukuhlola iziqinisekiso ezihlobene nomkhiqizo ngamunye kungakunikeza isiqondiso esengeziwe lapho wenza isinqumo sakho.I-BSLBATT ineminyaka engaphezu kwengu-10 yokuhlangenwe nakho kwasembonini ocwaningweni lwebhethri nokukhiqiza.Uma okwamanje ulwela ukukhetha i-powerwall engabizi kakhulu, sicela ukhululeke ukuxhumana nonjiniyela bethu ukuze bakweluleke ngesixazululo esingcono kakhulu.
