Amasistimu elanga amaningi amukela ukubuyiselwa kwebhethri, nakuba ubunkimbinkimbi nezindleko zihluka ngohlobo lwe-inverter. Amabhethri ahlanganisiwe e-AC{1}afaka kalula nganoma iyiphi isistimu. Izinketho ezihlanganisiwe ze-DC-zidinga ama-inverter ayi-hybrid futhi zingase zidinge ukushintshwa kwesisetshenziswa uma isistimu yakho ingaphambi kuka-2018.
Amabhethri elanga ahlala isikhathi esingakanani?
Amabhethri e-lithium ekhwalithi{0}}ye-ion ahlinzeka ngeminyaka engu-10-15 yesevisi ngeziqinisekiso ngokuvamile ezihlanganisa iminyaka engu-10 noma 4,000-imijikelezo engu-6,000. Ukusebenza kwangempela kuvame ukweqa imigomo yesiqinisekiso-idatha yomhlaba wangempela ibonisa amasistimu amaningi agcina umthamo ongu-80%+ eminyakeni engu-12.
Ingabe amabhethri elanga ayasebenza phakathi nokucima kukagesi ngaphandle kwamaphaneli elanga?
Yebo. Amabhethri azimele angashaja kugridi futhi anikeze amandla ayisipele ngaphandle kwamaphaneli elanga. Kodwa-ke, amaphaneli elanga avumela ukushajwa kabusha kwebhethri phakathi nokucisha okunwetshiwe, okungase kunikeze isipele esingapheli uma ukukhanya kwelanga kubambisana futhi ukusetshenziswa kuhlala kunengqondo.
Ukwenza Isinqumo Sokufaka
Isikhathi esilungile sokufaka sincike kakhulu ezintweni ezintathu: inqubomgomo ye-net metering yohlelo lwakho lokusebenza, ukwethembeka kwamandla esifunda, namawindi enzuzo atholakalayo.
Faka amabhethri ngokushesha ngamasistimu elanga amasha uma ubhekene nanoma yini engaphansi kwe-net metering egcwele, uhlangabezana nokucisha okubalulekile okungaphezu kokungu-3-4 okubalulekile minyaka yonke, noma uhlala ezifundazweni ezinikeza izisusa ezinkulu zesitoreji. Ikhredithi yentela yenhlangano okungenzeka iphelelwe yisikhathi ekupheleni konyaka idala ukuphuthuma okwengeziwe kwamaphrojekthi ahlelelwe ngo-2025.
Linda kuphela uma uqinisekise ukulinganisa okuphelele kwensalela yezitolo iminyaka engu-10+, ukuthembeka okuhle kakhulu kwegridi, kanye nemikhawulo eqinile yebhajethi. Noma kunjalo, ukucacisa isitoreji{2}}isistimu elungile igcina ukukhetha kwesikhathi esizayo ngaphandle kwezindleko ezingeziwe.
Ekufakweni okukhona kwesola, buyisela kabusha amabhethri lapho isiguquli sakho sisondela eminyakeni yokushintshwa, izinqubomgomo ze-net metering ziba zimbi, noma izinxephezelo zasendaweni ziyatholakala. Ubunkimbinkimbi nezindleko zokubuyiselwa kwemali kusho ukuhlaziywa okuphelele kwezomnotho we-payback ngaphezu kokufakwa okusha.
Amasistimu okugcina amandla wamandla elanga aguqula i-solar kusukela kunsiza-yasemini kuphela ibe ukuzimela okuphelele kwamandla. Ubuchwepheshe bukhulile, izindleko zehle kakhulu, futhi izinhlaka zenqubomgomo ziya ngokuya zivuna ukwamukelwa kwesitoreji. Kubanikazi abaningi bezindlu abafaka i-solar ngo-2025, umbuzo awukona ukuthi bangeze amabhethri kodwa kunalokho imuphi usayizi kanye nekhemistri ehambisana kangcono nezidingo nezimo zabo ezithile.
