Uninzi lwezikhokelo zokulinganisa zikuxelela ifomula kwaye ume apho. Ifomula yinxalenye elula. Yintoni ekhwelisa abantu kufakelo lokwenyani yiyo yonke into eyijikelezileyo - umthamo osebenzisekayo oguqukayo ngekhemistri kunye nobushushu, isiguquli esingakwaziyo ukunikezela ngeemfuno zempompo yequla, okanye inombolo yokuzimela ekhangeleka ilungile ephepheni kude-kunamafu eentsuku ezintathu akhuphe ibhanki ngexesha lesidlo sasemini kusuku lwesibini.
Esi sikhokelo sihamba silinganisa ibhanki yebhetri ngendlela umyili wenkqubo asondela ngayo kuyo: qala ngemithwalo yokwenyani, sebenzisa ifomyula engundoqo, emva koko ulungelelanise ubunyani bobunjineli i-equation yencwadi eshiya ngaphandle. Ekugqibeleni uzakuba noluhlu lwesikhundla ungathengela - hayi nje inani kwibhodi emhlophe.
Kufuneka ibenkulu kangakanani iBhanki yebhetri yeSolar?
Ubudlelwane bobungakanani obungundoqo bu:
Umthamo osebenzisekayo ofunekayo (Wh)=Ukusetyenziswa kwamandla ngemihla (Wh) × Iintsuku zokuzimela
Emva koko yahlula ngobunzulu obujoliswe kuko bokukhutshwa (i-DoD) ukuze ufumane umthamo ofunekayo ukuze uthenge:
Umthamo wesiqhelo (Wh)=Umthamo ofunekayo osebenzisekayo ÷ iqhezu elisebenzisekayo
Ukuba iibhetri zakho zibekwe kwi-amp{0}}iiyure kunewatt{1}}iiyure, guqulela nge:
Ah=Wh ÷ amandla ombane enkqubo
Oko kukufumana indawo yokuqala ekhuselekayo. Yintoni eyijikayo ibe luyilo lokwenyani lubalo lwekhemistri yebhetri,{1}}uhambo oluya nokubuya, imida ye-inverter, imithwalo yokunyuka, ubushushu, kunye nefestile yokutshajwa kwakhona kwelanga. Inxalenye yeli nqaku ichaza ukuba njani.
Inqaku kwifomula: ezinye izikhokelo zibhala "ukusetyenziswa kwemihla ngemihla × ixesha lokugcina kwiiyure," esebenza kuphela ukuba uyahlulahlula. Ukusebenzisaiintsuku zokuzimelaigcina iiyunithi zingaguquguquki kwaye inqanda eyona mpazamo ixhaphakileyo yokulinganisa esiyibona kwiiforam ze-DIY.
Umthamo Webhetri vs Imveliso yamandla
Ngaphambi kokuba naliphi na inani lithetha nantoni na, kunceda ukwahlula izinto ezimbini abantu bahlala bedibanisa:
- Umthamo (Wh okanye kWh)- angakanani amandla agcinwe yibhanki. Yile nto ibala iifomula zobungakanani.
- Amandla (W okanye kW)- ukuba amandla anokuhanjiswa ngokukhawuleza kangakanani ngexesha elithile. Oku kunqandwa ngu C-yebhetri kwaye, rhoqo, sisiguqulisi.
