Lobu buchwepheshe bungase buqede ukuyekethisa kwamanje kokuhlanganisa.
Ukuhlanganiswa kwamasistimu okugcina amandla elanga namagridi ahlakaniphile kunika amandla ukuphathwa nokusatshalaliswa kwamandla okungcono ngobuchwepheshe bokuxhumana obuthuthukisiwe, okuvumela{0}}ukuqapha kwesikhathi sangempela nokulawula ukuhamba kwamandla. Izimakethe zamandla ashintshayo zingase zivele lapho amasistimu e-solar{2}}asabalalisiwe ahweba ngamandla nezinsizakalo ngokuzenzakalelayo ngokusekelwe-kumasignali entengo yesikhathi sangempela kanye nezidingo zegridi.
imibuzo ejwayelekile ukubuzwa
Ngingakwazi ukwengeza isitoreji kumaphaneli ami elanga akhona?
Yebo, ngokuhlanganiswa okuhlanganisiwe kwe-AC{0}. Amasistimu ebhethri ahlanganisiwe e-AC{2}axhumeka ekufakweni okukhona kwe-solar ngaphandle kokulungisa okokusebenza kwe-solar. Isiguquli sebhethri esihlukile silawula ukushaja nokukhipha ngenkathi isiguquli selanga esikhona siqhubeka nokusebenza singashintshile. Le ndlela yokubuyisela ngokuvamile ibiza kancane emsebenzini futhi ayiziqedi iziqinisekiso zemishini yelanga, nakuba idela ukusebenza kahle okuthile uma kuqhathaniswa namasistimu ahlanganisiwe e-DC{5}}aklanywe ndawonye kusukela ekuqaleni.
Kwenzekani emandleni elanga uma amabhethri egcwele?
Uma amabhethri efika ekushajweni okugcwele, isistimu inezinketho ezintathu kuye ngokucushwa. Amasistimu-ahlanganisiwe egridi athekelisa amandla engeziwe kunsizakalo, azuza amakhredithi ngaphansi kwezinhlelo zensalela zamamitha. Amasistimu{3}egridi avaliwe anciphisa ukukhiqizwa kwelanga ngokususa ukusebenza kwephaneli kude nendawo enkulu yamandla. Amasistimu amaHybrid angase aphambukise amandla kusitoreji esishisayo noma imithwalo evimbelayo njengama-heaters amanzi. Amasistimu esimanje alawula lokhu ngokuzenzakalelayo ngokusebenzisa ama-algorithms okulawula i-inverter abeka phambili-ukuzisebenzisa, ukushaja ibhethri, nokuthekelisa kwegridi ngokusekelwe kulokho okuthandwayo okuhleliwe.
Ingabe amasistimu esitoreji elanga ahlanganisiwe-ayasebenza phakathi nokucisha kwegridi?
Kuncike ekwakhiweni kwesistimu. Igridi evamile-i-solar eboshiwe ngaphandle kwendawo yokubeka iyavaleka phakathi nokucisha ukuze kuphephe{2}}ivimbela i-backfeed engalimaza izisebenzi zensiza. Ukwengeza isitoreji sebhethri kuvumela ukusebenza kwekhophi yasenqolobaneni uma isistimu ihlanganisa ukushintsha kokudlulisa kanye nekhono lokuhlala. I-inverter ithola ukuphuma, inqamule kugridi, futhi inike amandla iphaneli yemithwalo eyisipele evela elanga nasebhethrini. Akuwona wonke amasistimu ahlanganisiwe afaka lokhu kusebenza{6}}kudinga okokusebenza okukhethekile futhi ngokuvamile kubiza ngaphezulu. Amasistimu e-off{8}egridi asebenza ngokwemvelo ngokuzimela ngaphandle kokunaka isimo segridi.
Ngidinga umthamo ongakanani wesitoreji kusistimu yami yelanga?
Izidingo zamandla zincike ezinhlosweni zokusebenza kunosayizi we-solar. Ngezinhlelo zokusebenza eziyisipele, bala ukusetshenziswa kwansuku zonke kwemithwalo ebucayi bese uphindaphinda ngezinsuku eziyisipele ozifunayo. Ikhaya elivamile elisebenzisa u-30 kWh nsuku zonke elinemithwalo ebalulekile engu-10 kWh lidinga isitoreji esingu-10-20 kWh sokwenza ikhophi yasenqolobaneni eyodwa{7}}yezinsuku ezimbili. Ukuze ushintshe ukulayisha, hlaziya isikhathi-sokusebenzisa{9}}izakhiwo zesilinganiso nosayizi wesitoreji ukuze ushintshele ezikhathini zamanani aphezulu. Izinhlelo eziningi zokuhlala zisebenzisa u-10-20 kWh, kuyilapho izinhlelo zezohwebo zisukela ku-50 kWh ziye kuma-MWh amaningana ngokusekelwe kumaphrofayili omthwalo wesikhungo kanye nezinjongo zomnotho.
Izinhlelo zokugcina amandla elanga zihlanganisa ngempumelelo ngokusebenzisa izakhiwo eziningi ezifakazelwe. Ukuhlanganisa i-AC kunikeza ukuguquguquka kwe-retrofit kanye nokusebenza ngezindlela ezihlukahlukene. I-DC coupling iletha ukusebenza kahle okuphezulu kanye nezindleko eziphansi zokufakwa okusha. Izindlela ze-Hybrid zihlanganisa izinzuzo zezinhlelo zokusebenza ezikhethekile.
Izinselele zokuhlanganisa-eziyinkimbinkimbi zezobuchwepheshe, izithiyo zokulawula, imikhawulo yengqalasizinda{1}}ziyasingathwa ngendlela ehlelekile ngokuthuthukiswa kobuchwepheshe, ukusekelwa kwenqubomgomo, nolwazi olukhulayo lokuphakelwa. Ukukhula okusheshayo kwemakethe kusuka ku-$93.4 billion ngo-2024 kuya ku-$378.5 billion ngo-2034 kukhombisa ukuthuthukiswa kwezomnotho kanye neziphakamiso zenani elifakazelwe.
Impumelelo idinga ukufanisa izakhiwo zokuhlanganisa nezimfuneko zephrojekthi ethile, ukufakwa kochwepheshe ngochwepheshe abaqeqeshiwe, nokuthuthukiswa kwesistimu okuqhubekayo. Ubuchwepheshe busebenza ngokwethembeka uma buklanywe kahle futhi busetshenziswa, njengoba kuboniswa ngamakhulu ezinkulungwane zamasistimu okusebenza emhlabeni jikelele.
