Wɔ tender ahorow mu wɔ Nigeria, Kenya, South Africa, Egypt, Morocco, Tanzania ne Côte d’Ivoire nyinaa mu no, ɔkwan a wɔtaa fa so susuw nneɛma ho ne sɛ wɔde bo a wɔde to amp-hour biara so — na ɛkame ayɛ sɛ saa kwan no ma wonya awerɛhyem sɛ wɔbɛpaw nea ɛnteɛ. Ɛde ɛka atitiriw abiɛsa sie wɔ bo a wɔde tɔ no akyi. Nea edi kan ne nea wɔde besi ananmu no dodow: mfe dumien VRLA hia biako a wɔde besi ananmu wɔ mfe dunum mu, mfe aduonu lead-carbon nhia biara, na sɛ bo mu nsonsonoe no sua sen ɛka a wɔbɔ wɔ biako a wɔde besi ananmu ho nyinaa a, kɔbere-carbon bo yɛ mmerɛw. Nea ɛtɔ so mmienu ne beaeɛ nsrahwɛ ho ka: baabi a egye nna mmienu ansa na beaeɛ bi adu no, obiako a ɔbɛsesa no akwantuo ne adwumayɛfoɔ bɛtumi ayɛ pɛ ne batere boɔ 30% kɔsi 60%, na ɛno mu biara mpue wɔ nsɛm a wɔafa aka no mu. Nea ɛto so abiɛsa ne ahoɔden: batere twetwe ankasa-discharge ne float current, na float ahoɔden yɛ soronko mpɛn pii wɔ mfiridwuma ahorow ntam — wɔ diesel-powered off-grid mmeae a ɛhwere dan tẽẽ kɔ pɛtro. Fa abiɛsa no ka ho na unit bo a ɛba fam koraa no bɛyɛ ne nyinaa ka a ɛkorɔn sen biara.

TCO Kotoku Anum no

Bue TCO mu yɛ no kotoku anum, a emu biara bu akontaa wɔ mfe dunum mu. Kotoku biako ne kapital: battery bo, akwantu, instɔlehyɛn, ne racks ne cableling a ɛbata ho. Kotoku abien ne nea wɔde besi ananmu: nya dodow a wɔde besi ananmu fi nhyehyɛe nkwa nna mu, na kan batere bo, akwantu, adwumayɛfo ne nea wɔtow gu bere biara. Kotoku abiɛsa ne adwumayɛ: nhwehwɛmu mpɛn dodow × ɛka a wɔbɔ wɔ nsrahwɛ biara mu, ne tumi sɔhwɛ. Kotoku anan yɛ ahoɔden: ahoɔden a ɛsensɛn nsu mu wɔ watt × nnɔnhwerew 8,760 × mfe 15 × mpɔtam hɔ anyinam ahoɔden bo, a wɔdan no diesel a wɔyɛ no ho ka wɔ mmeae a ɛnyɛ anyinam ahoɔden. Kotoku anum yɛ bo a aka ne nea wɔsan de di dwuma: kɔbere a wɔasɛe no a wɔsan nya no sie ɛka a wɔbɔ wɔ kɔbere-asikre ho no fã bi, bere a lithium a wɔsan de di dwuma ho nhyehyɛe da so ara yɛ teateaa na wɔbɔ ho ka dodow no ara sɛ nwura a asiane wom a wɔtow gu wɔ ɔmantam no mu. Anum no akyi no, kyerɛw outage cost separately — service credits a ɛsɛ sɛ wotua bere a backup di nkogu no yɛ sika ankasa wɔ SLA ase.

Mfe Dunum Sika a Wɔde Ma Mfiridwuma Abiɛsa
