I-Tesla, i-Huawei, i-LG, i-Sonnen, i-SolarEdge, i-BSLBATT, zimbalwa ezimbalwa kwiimpawu zebhetri zelanga zasekhaya ezithengiswa kwaye zifakwe yonke imihla, ngokukhula kwamandla ahlaziyekayo aluhlaza kunye nenkxaso-mali evela kwimigaqo-nkqubo yesizwe. Kodwa bona apha... Kwi-70% yamatyala, ibhanki yebhetri yelanga efakwe ekhaya ayisebenzi ngokufanelekileyo kwaye ayihambelani neempawu zenkqubo ye-PV, ngaloo ndlela iguqule ibe yi-investment embi kwaye ingenanzuzo. Masijongane nayo, injongo yodwa yebhetri yelanga yasekhaya kukuvelisa ukonga ngenkqubo yePV, kodwa kaninzi ayisetyenziswanga ngokufanelekileyo, ngokuchanekileyo kuba uthenga imveliso eneempawu ezingafanelekanga. Kodwa zeziphi iimpawu ekufuneka iinkqubo zebhetri zelanga zasekhaya zisebenze kakuhle? Yintoni omele uyijonge xa ukhetha ibhetri yokugcina amandla ekhaya ukuze ugweme ukuchitha imali? Makhe sifumanise kunye kweli nqaku. 1. Umthamo webhetri. Njengoko igama lisitsho, umsebenzi weipakethe yebhetri yelanga yasekhayakukugcina amandla agqithisileyo avelisiweyo yinkqubo ye-PV emini ukuze isetyenziswe ngokukhawuleza xa inkqubo ingasakwazi ukuvelisa amandla aneleyo ukunika amandla umthwalo wekhaya. Umbane wasimahla oveliswa yinkqubo udlula endlwini, unika amandla izixhobo ezifana nezikhenkcezisi, oomatshini bokuhlamba kunye neepompo zobushushu, emva koko ufakwe kwigridi. Ibhetri ye-lithium yaseKhaya yenza kube lula ukubuyisela la mandla angaphezulu, ebeya kuthi mhlawumbi anikwe urhulumente, kwaye ayisebenzise ebusuku, ukuthintela isidingo sokutsala amandla ongezelelweyo ngomrhumo. KwiNdlu yeGesi yeZerø (eyinto yombane ngokupheleleyo), ukugcinwa kwebhetri yelanga yasekhaya kubalulekile kuba, njengoko idatha iphanda kunye neengxelo, ukuveliswa kwemveliso yasebusika yenkqubo ayikwazi ukuhlangabezana kunye nokwanelisa ukufunxa kwamandla epompo yokushisa. Umda kuphela ukuba umisela ubungakanani benkqubo yePV. ● Indawo yophahla ● Uqingqo-mali olukhoyo ● Uhlobo lwesixokelelwano (isigaba esinye okanye isigaba sesithathu) Kwibhetri yelanga laseKhaya, ubungakanani bubalulekile. Ubukhulu besakhono sebhanki yeSolar yaseKhaya, kokukhona sikhulu isixa-mali esikhulu senkcitho yenkuthazo kunye nokukhulu ukonga "okwenzekayo" okwenziwa yinkqubo yePV. Ukulinganisa okufanelekileyo, ndincoma ukuba ibhetri yelanga ye-lithium ion ilinganiswe ngokuphindwe kabini kumthamo wenkqubo yePV. Ukuba unenkqubo ye-5 kW, ngoko ingcamango kukuba uhambe ngeIbhanki yebhetri ye-10 kWh. Inkqubo ye-10 kW?20 kWh ibhetri. Kwaye nangokunjalo… Oku kungenxa yokuba ebusika, xa imfuno yombane iphezulu, inkqubo ye-PV ye-1 kW ivelisa malunga ne-3 kWh yamandla. Ukuba ngokwe-avareji 1/3 yale mandla ifunxwa zizixhobo zasendlini ukuze zizisebenzise, i-2/3 yondliwa kwigridi. Ke ngoko, ibhanki yebhetri yelanga yasekhaya ephindwe kabini ubukhulu benkqubo iyafuneka. Entwasahlobo nasehlotyeni, iinkqubo zelanga zivelisa amandla amaninzi, kodwa umthamo wamandla ogcinwe awunyuki ngokufanelekileyo. Ngaba uyafuna ukuthenga isixokelelwano esikhulu sebhetri? Ungayenza loo nto, kodwa inkqubo enkulu ayithethi ukuba uya konga imali eninzi. Unokufuna ukugxila kuncinci nangaphezulu, okanye ngcono, utyala imali ngobulumko ngakumbi kwinkqubo yebhetri esebenzela wena, mhlawumbi ngeepaneli zewaranti ezingcono okanye iimpompo zokushisa ezisebenza ngcono. Umthamo linani nje, kwaye imigaqo yokumisela ubungakanani bebhetri yelanga yasekhaya ikhawuleza kwaye ilula, njengoko ndikubonise nje. Nangona kunjalo, iiparamitha ezimbini ezilandelayo zinobugcisa ngakumbi kwaye zibaluleke ngakumbi kwabo bafuna ngokwenene ukuqonda indlela yokufumana imveliso efanelekileyo esebenza kakuhle. 2. Ukutshaja kunye nokukhupha amandla. Kuvakala kungaqhelekanga, kodwa ibhetri kufuneka ihlawuliswe kwaye ikhutshwe, kwaye ukwenzela ukuba ibe ne-bottleneck, isithintelo, kwaye loo mandla alindelwe kwaye alawulwa yi-inverter. Ukuba inkqubo yam yondla i-5 kW kwigridi, kodwa ibhanki yebhetri yelanga yasekhaya ibiza kuphela i-2.5 kW, ndisachitha amandla ngenxa yokuba i-50% yamandla iyondliwa kwaye ayigcinwa. Okoko kwamibhetri yelanga yasekhayainamandla akukho ngxaki, kodwa ukuba ibhetri yam ifile kwaye inkqubo ye-PV ivelisa ixesha elincinci kakhulu (ebusika), amandla alahlekileyo athetha imali elahlekileyo. Ngoko ndifumana ii-imeyile ezivela kubantu abane-10 kW ye-PV, i-20 kWh yebhetri (ngoko ubungakanani obuchanekileyo), kodwa i-inverter inokusingatha kuphela i-2.5 kW yokutshaja. Ukutshaja/ukukhupha amandla nako kuchaphazela ixesha lokutshaja kwebhetri yelanga lelanga. Ukuba kufuneka nditshaje ibhetri ye-20 kWh ene-2.5 kW yamandla, ndifuna iiyure ezisi-8. Ukuba endaweni ye-2.5 kW, ndihlawula nge-5 kW, ithatha isiqingatha selo xesha. Ngoko uhlawula ibhetri enkulu, kodwa usenokungakwazi ukuyibiza, kungekhona ngenxa yokuba inkqubo ayivelisi ngokwaneleyo, kodwa ngenxa yokuba i-inverter icotha kakhulu. Oku kwenzeka rhoqo ngeemveliso "ezidibeneyo", ngoko ke ndine-inverter ezinikeleyo ukufanisa imodyuli yebhetri, uqwalaselo lwalo luhlala lunandipha lo mda wesakhiwo. Ukutshaja/ukukhupha amandla ukwaluphawu oluphambili lokuxhaphaza ngokupheleleyo ibhetri ngexesha leemfuno eziphezulu. Kusebusika, intsimbi yesi-8 ebusuku, kwaye indlu ichwayitile: iipaneli zokungenisa amandla elanga zisebenza ku-2 kW, impompo yobushushu ityhala isifudumezi ukuba sitsale enye i-2 kW, ifriji, iTV, izibane kunye nezixhobo ezahlukeneyo zisathatha i-1 kW kuwe. , kwaye ngubani owaziyo, mhlawumbi unemoto yombane yokutshaja, kodwa masiyikhuphe kwi-equation okwangoku. Ngokucacileyo, phantsi kwezi meko, amandla e-photovoltaic awaveliswanga, uneebhetri zokutshaja, kodwa awunyanzelekanga ukuba "uzimele okwethutyana" ngokuchanekileyo kuba ukuba indlu yakho idinga i-5 kW kunye nebhetri yelanga yendlu ibonelela nge-2.5 kW kuphela, oku kuthetha ukuba i-50% amandla usathatha kwigridi kwaye uyihlawulela. Uyawubona lo mnqa? Ngelixa ibhetri yelanga yendlu itshaja, uphoswa ngumba ophambili okanye, ngakumbi, umntu okubonelele ngemveliso ukunike eyona nkqubo inexabiso eliphantsi apho anokwenza eyona mali eninzi ngaphandle kokukunika ulwazi ngayo. Ewe, kusenokwenzeka ukuba naye akazazi ezi zinto. Idityaniswe kwintlawulo / amandla okukhutshwa kukuvula iibakaki zengxoxo yesigaba se-3 / isigaba esisodwa kuba ezinye iibhetri, umzekelo, iibhetri ze-2 ze-BSLATT azikwazi ukufakwa kwinkqubo yesigaba esisodwa ngenxa yokuba iziphumo zombane zidibanisa (10 + 10). = 10) ukufikelela kumandla afunekayo kwizigaba ezithathu, kodwa siya kuxubusha oko kwelinye inqaku. Ngoku makhe sithethe ngeparameter yesithathu ekufuneka uyiqwalasele xa ukhetha ibhetri yendlu: uhlobo lwebhetri. 3. Uhlobo lwebhetri yeSolar yaseKhaya. Qaphela ukuba le parameter yesithathu yeyona "jikelele" kwezi zintathu zinikiweyo, kuba inemiba emininzi ekufanele iqwalaselwe, kodwa ikwinqanaba lesibini kwiiparamitha ezimbini zokuqala ezisanda kuboniswa. Ulwahlulo lwethu lokuqala lweteknoloji yokugcina kwindawo yalo yokunyuka. AC-alternating okanye DC-continuous. Isishwankathelo esincinci esisisiseko. ● Iphaneli yebhetri yenza amandla eDC ● Umsebenzi we-inverter yenkqubo kukuguqula amandla avela kwi-DC ukuya kwi-AC, ngokweeparamitha zegridi echaziweyo, ngoko ke inkqubo yesigaba esisodwa yi-230V, 50/60 Hz. ● Le ngxoxo inempumelelo, ngoko ke sinepesenti engaphezulu okanye encinci yokuvuza, oko kukuthi, “ilahleko” yamandla, kwimeko yethu sithatha ukusebenza kakuhle kwe-98%. ● Ibhetri yelanga itshaja ngamandla eDC, hayi i-AC. Ngaba yonke loo nto icacile? Kulungile... Ukuba ibhetri ikwicala le-DC, ngoko kwi-DC, i-inverter iya kuba nomsebenzi wokuguqula amandla okwenene awenziwe kwaye asetyenziswe, ukuhambisa amandla aqhubekayo enkqubo ngokuthe ngqo kwibhetri - akukho kuguqulwa okufunekayo. Ngakolunye uhlangothi, ukuba ibhetri yelanga yendlu ikwicala le-AC, sinamaxesha angama-3 inani lokuguqulwa kune-inverter. ● I-98% yokuqala ukusuka kwiplanti ukuya kwigridi ● Ukutshaja okwesibini ukusuka kwi-AC ukuya kwi-DC kunika ukusebenza kakuhle kwe-96%. ● Ukuguqulwa kwesithathu ukusuka kwi-DC ukuya kwi-AC ukuze kukhutshwe, okubangelwa ukusebenza kakuhle kwe-94% (kuthatha i-inverter esebenzayo eqhubekayo ye-98% kwaye ingathatheli ingqalelo ilahleko ngexesha lokutshaja nokukhupha, kuyo nayiphi na imeko). Esi sicwangciso, esamkelwe ngobuninzi bokugcinwa kunye neTesla, kubangela ukulahlekelwa kwe-4% xa kuthelekiswa namanye amatyala. Ngoku kubalulekile ukubonisa ukuba ukuhlangana kwezi teknoloji zimbini sisigqibo sokufakela ibhanki yebhetri yelanga yasekhaya ngelixa ukwakhiwa kwenkqubo ye-PV, ekubeni imiba ye-AC isetyenziswa kakhulu xa kuhlaziywa, okt ukufakela ibhanki yebhetri yelanga yasekhaya kwinkqubo ekhoyo. , ekubeni abafuni ukuguqulwa okubalulekileyo kwinkqubo ye-PV. Enye inkalo yokuqwalasela xa kuziwa kuhlobo lwebhetri yikhemistri yokugcina. Ingaba i-LiFePo4 (LFP), i-Li-ion ecocekileyo, i-NMC, njl., inkampani nganye inamalungelo awodwa omenzi, isicwangciso sayo. Yintoni esifanele siyijonge? Yiyiphi onokuyikhetha? Ilula: inkampani nganye yeeseli zelanga ityala izigidi kuphando kunye namalungelo awodwa omenzi wechiza ngenjongo elula yokufumana eyona bhalansi ilungileyo phakathi kweendleko, ukusebenza kakuhle kunye nesiqinisekiso. Xa kuziwa kwiibhetri, le ngenye yezona zinto zibalulekileyo: isiqinisekiso sokuqina kunye nokusebenza komthamo wokugcina. Isiqinisekiso ke ngoko siba yiparameter engalindelekanga "yeteknoloji" esetyenzisiweyo. Ibhetri yelanga yaseKhaya sisincedisi, njengoko besitshilo, sisebenzela ukusebenzisa ngcono inkqubo ye-photovoltaic kunye nokwenza ukonga ekhaya. Ukuba ufuna ukwenza utyalo-mali ngaphandle kokuzisola, kufuneka uye kwiingcali ezinzulu neziqeqeshwe kakuhle kunye neenkampani zokuthenga.ibhanki yebhetri yelanga yasekhaya. Ungakuphepha njani ukwenza iimpazamo xa uthenga kwaye uthengela iibhetri zelanga zasekhaya? Kulula, jikela kumntu oqeqeshiweyo nonolwazi okanye inkampani ngoko nangoko,BSLBATTubeka umthengi embindini weprojekthi, hayi ezabo umdla. Ukuba ufuna inkxaso eyongezelelekileyo, i-BSLBATT inelona qela libalaseleyo leenjineli zentengiso kwaye iya kuba sendleni yakho ukukukhokela ekukhetheni eyona bhetri ifanelekileyo yelanga yelanga kwinkqubo yakho yePV.
