Ithini imakethe yamanje ye-PHOTOVOLTAIC yokugcina amandla?

Eqinisweni, abanye abakhiqizi be-inverter bebelokhu bethuthukisa futhi bakhiqiza ama-inverters okugcina amandla, kodwa kuphela eYurophu nase-United States nakwezinye izimakethe zamazwe ngamazwe, hhayi ezifuywayo, ngisho nase-pv yasekhaya ngokuqhubekayo ngo-2017, okuholela ekuqondeni okuncane kwamandla we-photovoltaic. isitoreji e-China. Kwaze kwafika kulo nyaka lapho inqubomgomo entsha ikhishwe lapho imakethe yasekhaya yokugcina amandla yaqala ukukhula futhi kungazelelwe yangena umbono womphakathi.

Kungenxa yokuthi kusesigabeni sokuqala sokutshalwa kwemakethe lapho izinga labahlinzeki bezinsizakalo lingalingani. Ngesikhathi esifanayo, inqubo yokufakwa kweziteshi zikagesi zokugcina amandla izoba nzima kakhulu futhi izidingo zamakhono zizothuthukiswa kakhulu. Ukukhetha abahlinzeki besevisi abavamile kungagwema izinkinga eziningi ezilandelayo.

Yimuphi umthamo webhethri engiwudingayo?

Ukuze siphendule lo mbuzo, kufanele siqale siqonde ukulandelana kokushaja nokukhipha iziteshi zamandla okugcina amandla. Kubahlali abajwayelekile, iziteshi zamandla okugcina amandla ngaphandle kwegridi zisetshenziswa kakhulu.

Emini, amandla akhiqizwa izitshalo ze-photovoltaic anikezwa kuqala ezindlini, kodwa kuyingxenyana encane yamandla, njengoba abantu besemsebenzini emini, futhi okuningi kugcinwa kumabhethri okugcina kuze kube yilapho sekushajwe ngokugcwele. . Uma kukhona okusele, kuya kugridi.

Ebusuku, amabhethri anika amandla umthwalo wasekhaya, igridi inikeza ukushoda, njalonjalo. Umdwebo olandelayo ubonisa ngokucacile.

E-Shanghai, ukusetshenziswa kukagesi kwanyanga zonke ekhaya elijwayelekile cishe kungama-400 KWH. Uma sicabanga ukuthi ukusetshenziswa kukagesi kungu-100 KWH phakathi no-300 KWH ebusuku, inqubo yokushaja nokukhipha ingaqedwa kanye ngosuku. Uma kucatshangelwa ukulinganiselwa kokushaja nokulahlekelwa kokukhipha nokujula kokukhishwa kwebhethri yokugcina amandla, ibhethri elinamandla angu-14kWh lifaneleka kakhulu. 0.8/10/0.9 = 13.9 kWh

Izimo ezicatshangelwayo: ukusebenza kahle kokushaja nokukhipha 90%, ukujula kokukhishwa okungu-80%

Ngaphansi kwezimo ezinjalo, iziteshi zamandla e-photovoltaic zidinga ukukhiqiza amandla angaba ngu-430 degrees ngenyanga, futhi indlela yokubala ithi: 300/0.9+100=433 degrees. Khona-ke iziteshi zamandla e-photovoltaic zidinga ukukhetha ukufeza umthamo ongakanani?

Isithombe

Okungenhla ukukhiqizwa kwamandla onyaka kwesiteshi samandla se-photovoltaic esingu-5400W e-Pudong New Area yase-Shanghai. Isamba salo saminyaka yonke sikagesi esiphehlwayo silinganiselwa ku-5600 KWH, nesilinganiso sanyanga zonke sikagesi esiphehlwayo esingama-471 KWH, ngaphezu kuka-433 KWH, ngokuyisisekelo sihlangabezana nokuqagela okungenhla, nensalela encane.

Ngokuvamile, ngaphansi kwesimo sokuthi ukusetshenziswa kukagesi kwanyanga zonke kumayelana ne-400 KWH (kuhlanganise ne-300 KWH ebusuku), ukukhetha i-5400W photovoltaic power station kanye nebhethri ye-14kWh yokugcina amandla kuyoba yisinqumo esinokwethenjelwa, esingamboza isidingo sikagesi semindeni evamile. izimo eziningi. Ngesikhathi umsebenzisi efika ekhaya, ibhethri seligcine amandla angaba ngu-14 degrees, awanele ngokuyisisekelo ukuthi asetshenziswe ebusuku, ngokuthembela okuncane kugridi yomphakathi kanye nokuzimela kwangempela.

Yebo, lokhu okungenhla kuwuhlelo lokulinganisa olulula kakhulu, futhi uhlelo lokusebenza lwangempela kufanele futhi luhlanganiswe nokusetshenziswa kwamandla omsebenzisi, ikakhulukazi ekusetshenzisweni kwamandla okuphakeme ehlobo kanye nokuncishiswa kukagesi, ibhethri yokulondoloza amandla izokwehlulwa ngokufanele.

Sibiza malini isiteshi sokugcina amandla?

Uma kunegama elilodwa kuphela elichaza intengo yamaseli okugcina amandla e-photovoltaic, kufanele kubize. I-Powerwall 13.5 degrees icashunwe ku-$6,600, noma 45,144 yuan, noma cishe 3,344 yuan ngedigri ngayinye. Umlingiswa ohlobene, isicaphuno somkhiqizi wasekhaya sinomusa kakhulu, ngokuvamile sibe ngu-1800 yuan/degree ohlangothini lwesobunxele nakwesokudla, kodwa gcina amadigri angu-14 kagesi ukuze uthole futhi izinkulungwane ezingama-25.

Isithombe

Futhi isamba sezindleko zesiteshi samandla ahlakaniphile esingu-5400W esingu-6.68 yuan/W manje sesingaba ngu-36,000 yuan, okulingana nemakhaphu engaba ngu-60%. Kuyizinsuku zakuqala, kodwa nginesiqiniseko sokuthi kunenqwaba yezigebengu ezifuna ukuyizama kuqala.

04

Ibhethri kufanele lishintshwe kangaki?

Inkinga evamile yamabhethri e-lithium-ion ukuguga, okuhambisana nokulahlekelwa amandla, kodwa izinga lokuguga lihlukile. Futhi inqubo ishesha kakhulu kunama-solar panel. Nakuba amamojula ethembisa ukubola ngokungeqi ku-20% eminyakeni engu-20, amabhethri angabola ngo-40% cishe eminyakeni eyisikhombisa. Nakuba inombolo encane yemijikelezo ingaba ngu-6,000, lapho umthamo webhethri wehlele ku-60%, ukusebenza kwawo kuyawohloka futhi udinga ukucabangela ukushintsha ibhethri ukuze ungaphazamisi umuzwa wamandla ojwayelekile.

Isithombe

Kuleli qophelo, inqubomgomo yomkhiqizi ngemva kokuthengisa iyisici esibaluleke kakhulu okufanele icatshangelwe. Abakhiqizi abaningi bebhethri banikeza iwaranti yeminyaka engu-5 kuya kwengu-10, kodwa inqubomgomo yokushintshwa kwebhethri ayicacile, okudingeka kugxilwe kuyo.

05

Ingabe iziteshi zamandla ezikhona ezixhunywe kugridi zingathuthukiswa?

Ngokusobala, ingathuthukiswa ibe isiteshi samandla okugcina amandla ngokufaka amabhethri okugcina amandla nezinye izinto zokusebenza kanye nokumane kuguqule imigqa ekhona. Nokho, izibonelelo ezikhona empeleni ezeziteshi zamandla e-photovoltaic ezixhunywe kugridi. Uma sezithuthukiselwe esiteshini samandla okugcina amandla, uma sikhuluma nje, uxhaso olufanele luyobe lungasekho.

Ingabe ikhona indlela yokuzungeza lokho? Ukushiyela wena ukuthi ucabange ngenkinga, ngikholelwa ukuthi kunzima ukuwa.
