Ukuthenga imali noma uxhaso lwezimali lwezindlu ngokuvamile lunikeza umnotho ophelele ongcono.
imibuzo ejwayelekile ukubuzwa
Ngingakwazi ukwengeza ibhethri kusistimu yami yelanga ekhona?
Yebo, amabhethri angafakwa kabusha ekufakweni okukhona kwelanga. Amabhethri{1}ahlangene e-AC{1}asebenza nanoma yikuphi ukusethwa kwelanga, nakuba ungase udinge inverter entsha noma iphaneli encane. Izindleko zokufaka zigijima ngo-$1,000-2,000 ngaphezu kwamandla elanga ahlanganisiwe anokufakwa kwesitoreji sebhethri. Ikhredithi yentela yombuso isasebenza ekufakweni kabusha kwebhethri okuqedwe ngo-December 31, 2025.
Ibhethri lizonika amandla isikhathi esingakanani ikhaya lami phakathi nokucima?
Ubude besikhathi buncike kusayizi webhethri kanye nokusebenzisa kwakho ngesikhathi sokucisha. Ibhethri elingu-13.5 kWh elisebenzisa imithwalo ebalulekile (isiqandisi, izibani, amashaja efoni, i-inthanethi) ngokuvamile ihlala amahora angama-24-48. Imithwalo esindayo njengesipholisa-moya, ukushisa kukagesi, noma ukuphampa amabhethri ngokushesha. Amaphaneli elanga ashaja kabusha ibhethri phakathi namahora okukhanya kwasemini, anweba ubude besikhathi sokulondoloza ngokungenamkhawulo ngokulawulwa komthwalo ngokucophelela.
Yisiphi isikhathi sokukhokha sangempela sokugcina ibhethri?
Izikhathi zokukhokha zisukela kwengu-7-iminyaka engu-15 kuye ngamanani kagesi, amaphethini okusetshenziswa, nokutholakala kwenzuzo. Izimo zezindleko eziphezulu-ngesikhathi{4}so{4}so{7}}sokusebenzisa amanani abona ukukhokhelwa okusheshayo. Ikhredithi yentela yombuso engu-30% isheshisa kakhulu ukubuyisela-uhlelo lwama-$15,000 lubiza u-$10,500 ngemva kwamakhredithi. Ukonga konyaka okungu-$700-1,600 kuvamile ngokusekelwe kudatha ye-EnergySage kusukela ezinkulungwaneni zokufakwa.
Ingabe amabhethri adinga ukunakekelwa okuqhubekayo?
Ukunakekelwa okuncane kuyadingeka-akukho sevisi okuhleliwe kumasistimu amaningi ebhethri le-lithium. Gcina izindawo zokungenisa umoya zicacile, qinisekisa ukuthi izingxenyekazi zekhompuyutha ezikhwezwayo zihlala zivikelekile minyaka yonke, futhi uqaphe ukusebenza kwesistimu ngohlelo lokusebenza lweselula. Abakhiqizi baphatha izibuyekezo zesofthiwe bekude. Ngokungafani namajeneretha, amabhethri awanawo amanzi okushintsha noma izihlungi ezizoshintshwa.
Amandla elanga anesitoreji sebhethri aguqula amaphaneli elanga asuke-kumthombo wamandla wasemini kuphela abe isistimu yokuphatha amandla. Le nhlanganisela ikhuluma ngokuphazamiseka kokusebenza kwelanga, inikeza amandla ekhophi yasenqolobaneni ngesikhathi sokucima, futhi ithwebula inani eliphezulu lezomnotho emalini yakho yelanga. Njengoba izindleko zincipha, izinxephezelo zikahulumeni eziphelelwa yisikhathi maduze, kanye nokukhathazeka kokwethenjwa kwegridi okukhulayo, u-2025 umele iwindi elifanele lokwengeza isitoreji sebhethri kumasistimu elanga amasha noma akhona kakade.
Ubuchwepheshe bukhule ngaphezu-kwesimo sokutholwa ngaphambi kwesikhathi. Amakhulu ezinkulungwane zamasistimu ebhethri okuhlala manje asebenza ngempumelelo kulo lonke elase-US, afakazela umqondo ezimweni zezulu ezihlukene kanye nezimo zokusebenzisa. Njengoba izinqubomgomo ze-Net metering ziqhubeka ziba buthaka nezinga likagesi lilokhu likhuphuka, ingqondo yezezimali iyaqina. Amandla elanga anesitoreji sebhethri awasewona nje amandla ekhophi yasenqolobaneni-amayelana nokulawula izindleko zakho zamandla nokuthembeka emashumini eminyaka ezayo.
