Yiyiphi imarike yangoku ye-PHOTOVOLTAIC yokugcina amandla?

Enyanisweni, abanye abavelisi be-inverter baye baphuhlisa kwaye bavelisa i-inverters yokugcina amandla, kodwa kuphela kwiYurophu kunye ne-United States kunye nezinye iimarike zamazwe ngamazwe, kungekhona kwikhaya, nakwi-pv yasekhaya ngokujikeleza ngokupheleleyo kwi-2017, okubangelwa ukuqonda okuncinci kwamandla e-photovoltaic. yokugcina eTshayina. Akuzange kube kulo nyaka apho umgaqo-nkqubo omtsha wakhutshwa apho imarike yogcino lwamandla yasekhaya yaqala ukukhula kwaye yangena ngokukhawuleza kwimbono yoluntu.

Kungenxa yokuba kukwinqanaba lokuqala lokulinywa kweemarike apho umgangatho wababoneleli ngeenkonzo ungalingani. Ngelo xesha, inkqubo yofakelo lwezikhululo zamandla zokugcina amandla ziya kuba nzima ngakumbi kwaye iimfuno zezakhono ziya kuphuculwa kakhulu. Ukukhetha ababoneleli ngenkonzo rhoqo kunokunqanda iingxaki ezininzi ezilandelayo.

Ngowuphi umthamo webhetri endiwufunayo?

Ukuphendula lo mbuzo, kufuneka siqale siqonde ukutshaja kunye nokukhupha ulandelelwano lwezikhululo zamandla okugcina amandla. Kubahlali abaqhelekileyo, izikhululo zamandla okugcina amandla ngaphandle kwegridi zisetyenziswa kakhulu.

Emini, amandla avela kwizityalo ze-photovoltaic anikezelwa kuqala kumakhaya, kodwa yincinci encinci yamandla, enikezelwa ukuba abantu basemsebenzini emini, kwaye kuninzi ngakumbi kugcinwa kwiibhetri zokugcina kuze kube yilapho ihlawulwe ngokupheleleyo. . Ukuba kukho nayiphi na eseleyo, iya kwigridi.

Ebusuku, iibhetri zinika amandla umthwalo wekhaya, igridi inika ukusilela, njalo njalo. Lo mzobo ulandelayo ubonisa ngokucacileyo ngakumbi.

EShanghai, umbane osetyenziswa rhoqo ngenyanga kwikhaya eliqhelekileyo umalunga nama-400 KWH. Ukucinga ukuba ukusetyenziswa kombane yi-100 KWH emini kunye ne-300 KWH ebusuku, inkqubo yokuhlawula kunye nokukhupha ingagqitywa kanye ngosuku. Ukuqwalasela umda wentlawulo kunye nokukhutshwa kwelahleko kunye nokukhupha ubunzulu bebhetri yokugcina amandla, ibhetri enomthamo we-14kWh ifanelekile ngakumbi. 0.8/10/0.9 = 13.9 kWh

Iimeko ezicingelwayo: ukuhlawula kunye nokusebenza kakuhle kwe-90%, ukukhupha ubunzulu be-80%

Ngaphantsi kweemeko ezinjalo, izikhululo zamandla e-photovoltaic kufuneka zenze malunga ne-430 degrees zamandla ngenyanga, kwaye indlela yokubala: 300 / 0.9 + 100 = 433 degrees. Emva koko izikhululo zamandla ze-photovoltaic kufuneka zikhethe kangakanani ukufikelela?

Umfanekiso

Oku ngasentla kukuveliswa kwamandla ngonyaka kwesikhululo samandla se-photovoltaic se-5400W ePudong Indawo eNtsha yaseShanghai. Amandla onyaka ewonke avelisa malunga ne-5600 KWH, kunye ne-avareji yenyanga yokuvelisa amandla angama-471 KWH, ngaphezulu kwe-433 KWH, ngokusisiseko ehlangabezana noqikelelo olungentla, kunye nentsalela encinci.

Ngokubanzi, phantsi komqathango wokuba ukusetyenziswa kombane kwenyanga malunga ne-400 KWH (kubandakanywa ne-300 KWH ebusuku), ukukhetha isikhululo samandla se-5400W photovoltaic kunye ne-14kWh ibhetri yokugcina amandla iya kuba yinto ethembekileyo ngakumbi, enokugubungela imfuno yombane kwiintsapho eziqhelekileyo iimeko ezininzi. Ngethuba xa umsebenzisi efika ekhaya, ibhetri igcine malunga ne-14 degrees yamandla, eyaneleyo ngokusisiseko ukusetyenziswa ebusuku, ngokuthembela okuncinci kwigridi yoluntu kunye nokuzimela ngokwenene.

Kakade ke, oku ngasentla kuphela isikimu soqikelelo olulula kakhulu, kwaye isicelo esisiso kufuneka sidityaniswe nokusetyenziswa kwamandla omsebenzisi, ngakumbi kwincopho yokusetyenziswa kwamandla ehlotyeni kunye nokuthotywa kombane, ibhetri yokugcina amandla iya kugqithwa ngokufanelekileyo.

Ingaba isikhululo sokugcina amandla sixabisa malini?

Ukuba kukho igama elilodwa kuphela elichaza ixabiso leeseli zokugcina amandla e-photovoltaic, kufuneka libize. I-Powerwall 13.5 degrees icatshulwa kwi-6,600 ye-$, okanye i-45,144 ye-yuan, okanye malunga ne-3,344 ye-yuan ngeqondo. Umlinganiswa ohambelanayo, ucaphulo lomenzi wasekhaya unobubele ngakumbi, yiba kwi-1800 yuan / isidanga sasekhohlo nasekunene, kodwa gcina iidigri ezili-14 zombane ukuze ufumane ama-25 amawaka.

Umfanekiso

Kwaye ixabiso lilonke le-5400W yesikhululo samandla esihlakaniphile se-6.68 yuan /W ngoku malunga ne-36,000 ye-yuan, ilingana ne-markup malunga ne-60%. Ziintsuku zokuqala, kodwa ndiqinisekile ukuba zininzi iigeeks ezifuna ukuzama kuqala.

Kufuneka itshintshwe kangaphi ibhetri?

Ingxaki eqhelekileyo yeebhetri ze-lithium-ion iguga, ihamba kunye nokulahlekelwa kwamandla, kodwa izinga lokuguga lihlukile. Kwaye inkqubo ikhawuleza kakhulu kuneepaneli zelanga. Ngelixa iimodyuli zithembisa ukubola ngokungekho ngaphezulu kwe-20% kwiminyaka engama-20, iibhetri zinokubola nge-40% malunga neminyaka esixhenxe. Nangona inani eliqingqiweyo lemijikelezo lingafikelela kwi-6,000, xa amandla ebhetri ehla ukuya kwi-60%, ukusebenza kuyancipha kwaye kufuneka ucinge ngokutshintsha ibhetri ukuze ungachaphazeli amava aqhelekileyo ombane.

Umfanekiso

Kweli nqanaba, umgaqo-nkqubo wokuthengisa emva kokuthengisa yinto ebaluleke ngakumbi ekufuneka iqwalaselwe. Uninzi lwabavelisi beebhetri banikezela iwaranti ye-5 kwiminyaka eyi-10, kodwa umgaqo-nkqubo wokutshintshwa kwebhetri awucaci, okufuneka ugxininise.

Ngaba izikhululo zombane ezikhoyo eziqhagamshelwe kwigridi zinokuphuculwa?

Ngokucacileyo, inokuphuculwa kwisikhululo samandla okugcina amandla ngokufaka iibhetri zokugcina amandla kunye nezinye izixhobo kunye nokuguqula ngokulula imigca ekhoyo. Nangona kunjalo, izibonelelo ezikhoyo zenzelwe izikhululo zamandla ze-photovoltaic eziqhagamshelwe kwigridi. Nje ukuba ziphuculwe zibe kwisikhululo samandla okugcina amandla, xa sithetha ngokungqongqo, izibonelelo ezifanelekileyo ziya kube zingasekho.

Ngaba ikho indlela ejikeleze loo nto? Yiyeke nje kuwe ukuba ucinge ngengxaki, ndiyakholelwa ukuba kunzima ukuwa.
