Imibuzo Evame Ukubuzwa
Ingakanani idatha yemizuzu engu-15 edingekayo usayizi wesitoreji samandla se-C&I?
Sebenzisa idatha eyanele enesitembu sesikhathi ukumela ukukhiqizwa kwesizini, ukuhlala, i-HVAC, i-PV, nezimo zentela. Unyaka wokusebenza ogcwele uyathandeka uma utholakala, kodwa isikhathi sokugcina kufanele sikhethwe ngokuya ngokuhlukahluka kwesizinda kanye nesigaba sephrojekthi.
Ingabe izikweletu zikagesi zanyanga zonke zingasetshenziswa ekulinganisweni kokugcina kwebhethri?
Bangakwazi ukusekela ukuhlolwa kwangaphambi kwesikhathi nokubuyekezwa kwentela, kodwa ngokuvamile ababonisi ubude besikhathi somcimbi, ukuphakama okuphindaphindiwe, amawindi okushaja, noma ubudlelwano phakathi kokufunwa ne-PV. Ukulinganisa kokugcina kufanele kusebenzise idatha yesikhawu emngceleni wamamitha ofanele.
Uyini umehluko phakathi kwe-kW ne-kWh yokugcina?
I-kW amandla okukhipha ngokushesha noma amandla okushaja. I-kWh amandla atholakalayo ngokuhamba kwesikhathi. Ukushefa okuphezulu kudinga i-kW eyanele ukuze kuncishiswe isidingo esikhulu eseqile kanye ne-kWh esebenzisekayo eyanele ukuze kuqhubeke lokho kuncipha ngomcimbi ophelele.
Ingabe ibhethri kufanele lilinganiswe ukuze kuqedwe inani eliphakeme kakhulu elirekhodiwe?
Hhayi ngokuzenzakalelayo. Ukuphakama okuphezulu kakhulu kungase kube okungavamile noma kubize ukuqeda. Abathengi kufanele baqhathanise okuhloswe ngakho okumbalwa futhi bahlole ububanzi bezinto zokusebenza ezikhuphukayo ngokuqhathaniswa nenzuzo yentela ekhuphukayo nobungozi bokusebenza.
Ikhophi yasenqolobaneni yomthwalo obucayi kufanele ithinte kanjani umthamo wokushefa okuphezulu?
Chaza ubuncane besimo sokukhokhisa esigunyaziwe se-kW yomthwalo obalulekile nobude besikhathi. Ungawabali amandla afanayo agciniwe njengatholakala ngokugcwele ekuthunyelweni kwezentengiso kwansuku zonke ngaphandle uma isigaba sokusebenza sikuvumela ngokucacile.
I-PV isishintsha kanjani isibalo sesitoreji samandla se-C&I?
Sebenzisa i-PV eqondaniswe nesikhathi kanye nedatha yokulayisha ukuze uhlonze ukukhiqizwa kwensalela yangempela kanye nesikhathi sokuphakama kwesayithi. Umthamo we-nameplate we-PV uwodwa awubonisi ukuthi mangakanani amandla atholakalayo wokushaja noma ukuthi ahambisana nomcimbi wokufunwa.
Yini okufanele abathengi bayithumele ngaphambi kokucela ikhotheshini yephrojekthi?
Thumela umthwalo wesikhawu kanye nedatha ye-PV, imithetho yentela, ikhalenda yokusebenza, okuqondiwe okufunwayo, uhlu lomthwalo obalulekile, umdwebo womugqa owodwa, ugesi wokuxhuma, ulwazi lwamaphutha, indawo yesayithi, izimfuneko zokulawula, inani, indawo, okuqondiwe kokulethwa, nezivivinyo ezidingekayo namadokhumenti.
Cela Iphrofayili Yomthwalo kanye Nokubuyekeza Ukulungiselelwa
Lungiselela iphrofayela yomthwalo wesitembu sesikhathi, ubude besikhawu, imithetho yentela, inhloso yokusebenza eyinhloko, okuhlosiwe okuhlosiwe, idatha ye-PV, ishejuli yomthwalo obucayi, izingqinamba zokushaja, umdwebo womugqa owodwa, ugesi wokuxhuma, izimo zesayithi, ubuningi, indawo, okulindelekile kokuthunywa, nezimfuneko zokwamukela. Zihambise nge-Dingsheng’s ikhasi lokuxhumana kanye neprojekthi yokucaphuna. Ithimba lingabuyekeza izilungiselelo ezitholakalayo zesitoreji samandla, lihlonze usayizi ongekho noma idatha yesixhumi esibonakalayo sikagesi, liqhathanise amafomethi omkhiqizo afanelekile, futhi lilungiselele isiphakamiso esiqondene nephrojekthi ngokuqagela okushiwo, imingcele yokuhlinzeka, imibhalo, nokungafakwa.
