Izindawo ezibalulekile zingagcina ijeneretha noma omunye umthombo wokusekelayo wemicimbi engavamile.
Mangaki amaphaneli elanga adingwa umbhoshongo weseli?
Ayikho impendulo ethembekile evela ohlotsheni lombhoshongo kuphela. Inani lamaphaneli lincike emthwalweni wansuku zonke, isilinganiso samaphaneli, ukukhanya kwelanga kwenyanga, izinga lokushisa, umthunzi, ukulahleka kwesistimu, ukuqondiswa kanye nomkhawulo wokukhula. Qala nge-kWh ngosuku, hhayi umthetho ojwayelekile wephaneli ngombhoshongo.
Ingabe isayithi lezokuxhumana elisebenzisa amandla elanga lihlala lidinga i-inverter?
Cha. Imithwalo eminingi ye-telecom isebenzisa i-nominal -48 V DC futhi ingahlinzekwa ngesakhiwo se-DC esifanele. I-inverter iyadingeka emithwalweni ye-AC. Ukususa izigaba zokuguqulwa ezingadingekile kunganciphisa ukulahleka futhi kube lula indlela yamandla.
Kungakanani ukuzimela kwebhethri okufanele?
Umsebenzisi kufanele achaze ukuzimela kusukela ekuhlosweni kwesevisi, isimo sezulu, ukuthembeka komthombo kanye nesikhathi sokuphendula. Indawo esisizwa yigridi ingadinga amahora amaningi, kanti indawo ekude engaphandle kwegridi ingadinga isikhathi eside kakhulu. Ukuzimela isikhathi eside kwandisa izindleko, indawo ezungezile kanye nesidingo sokubuyisa.
Ingabe amaphaneli elanga angafakwa embhoshongweni we-telecom?
Zingafakwa kwezinye izilungiselelo ezithuthukisiwe, kodwa isakhiwo, ukulayisha komoya, ukufiphaza, umzila wekhebula, indawo ye-RF kanye nokufinyelela kokulungisa kumele kuhlolwe. Ukufakwa phansi kuvame ukuba lula uma kutholakala indawo evikelekile.
Iyiphi isayithi okunzima kakhulu ukuyisebenzisa?
Thumela iphrofayili yomthwalo, izixhumanisi, umlando wokungasebenzi kanye nomgomo wokuzimela ngokuxhumana kwakho nephrojekthi ye-Huijue esunguliwe. Okokuqala okuwusizo okulethwayo akulona uhlu lomkhiqizo; kuwukuqhathanisa amandla okusobala kanye nokwakheka kwezakhiwo.
