   Gwiritsani ntchito dongosolo lazachuma lomwe limaphatikizapo zida zamagetsi, posungira mphamvu, kuphatikiza, kulipiritsa mphamvu, kutayika kwachangu, kuwonongeka, kukulitsa, m'malo, O&M, ndalama, misonkho, kuchotsedwa, ndi mtengo wotsalira ngati kuli koyenera.

6. Yesani bankability.

   Unikani mphamvu zazachuma za ogula, mayendedwe, zitsimikizo, chitsimikizo cha magwiridwe antchito, udindo wa EPC,-ntchito zazitali, zosinthira, inshuwaransi, ndi kuvomereza kobwereketsa.

7. Thamangani ma sensitivity kesi.

   Yesani zomwe zingachitike ngati mitengo yamagetsi, kagwiritsidwe ntchito, mtengo wandalama, mphamvu, nthawi yosinthira, kuchedwa kwa projekiti, kapena nthawi{0}}yofunikira kusintha. Economics ya LDES imakhudzidwa kwambiri ndi momwe chuma chimagwiritsidwira ntchito komanso kuchuluka kwa mphamvu zomwe zimafunikira kwenikweni.

Malingaliro Olakwika Odziwika Okhudza LDES

"LDES Ndi Mtundu Wa Battery"

Ayi. Mabatire ndi gulu limodzi la matekinoloje a LDES. Makina, matenthedwe, mphamvu yokoka, ndi makemikolo amathanso kupereka mphamvu kwanthawi yayitali-.

"Chilichonse Choposa Maola 10 Ndi Bwino Kwambiri"

Ayi. Maola khumi ndi gawo lofunikira la DOE, osati chitsimikizo cha mtengo. Nthawi yowonjezera imapanga phindu pokhapokha ngati gululi kapena kasitomala akufuna mphamvu zowonjezera zosungidwa.

"Tekinoloje Yogwira Ntchito Kwambiri Ndi Yabwino Nthawi Zonse"

Ayi. Kuchita bwino kumakhudza mtengo wolipiritsa, koma LCOS imadaliranso kagwiritsidwe ntchito, kayendedwe ndi moyo wa kalendala, kusungirako{1}}ndalama zapakatikati, O&M, zosinthira, ndalama, ndi moyo wantchito.

"LDES Imangopereka Mphamvu Zosunga Zosungira"

Ayi. Kusunga zosunga zobwezeretsera kumadalira kamangidwe ka magetsi, zowongolera, malo akumtunda, chitetezo, zosungidwa-zosungirako mphamvu, zakuda-zoyambira zakuda{2}}pakufunika, ndi katundu wofunika kukhalabe wamphamvu.

"Lithium-Ioni Sangakhale LDES"

Izo ndi zolimba kwambiri. Lithium-ion ikhoza kukhazikitsidwa kwa nthawi yayitali-yogwira ntchito. Funso ndilakuti ngati kasinthidwe kameneka kamakhalabe mwaukadaulo, m'zachuma, komanso m'ntchito yopikisana ndi ntchito yofunikira.

Kutsiliza: Yambani ndi Ntchito Yofunikira Yamagetsi

Kusunga mphamvu-kwanthawi yayitali si mpikisano wotha kudziwa batire yomwe yapambana. Ndi gulu laukadaulo lomwe limathetsa mavuto osiyanasiyana munthawi zosiyanasiyana.

Pulojekiti yopangidwa kuti isamutse mphamvu yoyendera dzuwa kuyambira masana mpaka pakati pausiku ndiyosiyana kwambiri ndi yomwe ikufunika kuti isavutike ndi vuto longowonjezeranso masiku atatu. Yoyamba ingakomere{2}}makina amphamvu kwambiri omwe amazungulira tsiku lililonse. Chachiwiri chikhoza kuyika mtengo wapatali pa-mphamvu yamphamvu yotsika mtengo, yotsika-yodzithira, malo osungiramo madzi akuluakulu, kapena nthawi yayitali yosungira.

Ntchito zamphamvu kwambiri za LDES zimayamba ndi manambala atatu:zimafunika mphamvu, mphamvu zogwiritsiridwa ntchito, ndi nthawi yofunikira. Izi zikafotokozedwa, opanga amatha kufananiza matekinoloje pazinthu zomwe zimatsimikizira ngati polojekiti ingamangidwe, kulipidwa, kuyendetsedwa, ndi kulipiridwa kwa moyo wake wonse.
