Nsɛm a Wɔtaa Bisa
Bere tenten ahe na owia ahoɔden batere di dwuma bere a wɔabɔ no pɛnkoro no?
Eyi gyina anyinam ahoɔden a wode di dwuma so koraa. Battery a ɛyɛ 13 kWh a ɛma nneɛma a ɛho hia nkutoo (fridge, akanea, Wi-Fi, outlets kakraa bi a ne nyinaa yɛ 700W) di bɛyɛ nnɔnhwerew 18.

Battery no kɔ so yɛ adwuma, nanso ne tumi a ɛso atew-taa yɛ 60-70% wɔ mfitiaseɛ no mu. Batere a ɛyɛ kWh 10 no bɛyɛ batere a ɛyɛ kWh 6.5. Wubetumi de adi dwuma wɔ ahoɔden a wɔatew so, de asi ananmu ($6,000-8,000), anaasɛ wode batere a ɛto so abien aka nea edi kan no ho.

Nnɛyi nhyehyɛe dodow no ara yɛ modular na wotumi de boaboa ano. Tesla Powerwalls tumi de 4 units bom.

Nsɛm a Ɛwɔ Ase
Owia batere a wɔkora so nyɛ mfiridwuma a wɔsɔ hwɛ bio-ɛda no adi, ɛho akokwaw, na ɛrenya nkɔso a ɛpae. U.S. de battery a wɔde sie bɛka ho wɔ afe 2025 mu sen sɛnea na ɛwɔ ɔman no nyinaa mu mfeɛ mmiɛnsa a atwam no.
Nanso "mfiridwuma a wɔada no adi" nkyerɛ sɛ "amansan nyinaa sikasɛm mu ntease." Sikasɛm no gyina wo mpɔtam hɔ utility no rate nhyehyɛe, sɛnea wode nneɛma di dwuma, mpɛn dodow a wogyae adwuma, ne nneɛma a ɛkanyan wo a ɛwɔ hɔ no so koraa. Nhyehyɛe a etua ne ho ka wɔ mfe 4 mu wɔ California no betumi agye mfe 20 wɔ North Carolina.
Mfiridwuma no ankasa yɛ adwuma sɛnea wɔbɔ ho dawuru no. Lithium-ion batere no sie owia anyinam ahoɔden, ɛpue no bere a wɔhwehwɛ, ɛma anyinam ahoɔden a ɛboa bere a wɔatwa, na ɛtra hɔ mfe 10-15 a wonsiesie no kɛse. Nnuruyɛ no yɛ nea ɛfata, nsakrae a etu mpɔn no yɛ kɛse, na nhyehyɛe ahorow no ne nnɛyi owia ahoɔden a wɔde si hɔ no bom yiye.
Nea ɛresakra ne abɔde a nkwa wom a atwa batere ho ahyia no. VPP nhyehyeɛ a ɛtua wo ka wɔ grid dwumadie ho, berɛ-a -de -de di dwuma dodoɔ a ɛma nneɛma a wɔkora soɔ no som boɔ, ne utilities a ɛtew net metering mfasoɔ so-nneɛma a ɛfiri abɔnten yi ma sikasɛm akontabuo no kɔ storage so kɛseɛ. Wɔ afe 2020 mu no, 12% pɛ na wɔde batere ka ho. Eduu afe 2023 no, saa dodow no duu 32%, na nnwuma mu nhwehwɛmufo kyerɛ sɛ ebedu afe 2026 no, ɛbɛyɛ 45%.
Asɛmmisa no nyɛ sɛ ebia owia anyinam ahoɔden batere a wɔkora so no yɛ adwuma-ɛyɛ adwuma, ahotoso ne nea wotumi hyɛ ho nkɔm. Asɛmmisa no ne sɛ ebia ɛyɛ adwuma ma wo tebea pɔtee wɔ wo address pɔtee no so ne wo mfaso pɔtee ne nea wode di dwuma.

Ɛno ne nhwehwɛmu a ɛyɛ nokware. Owia anyinam ahoɔden batere a wɔkora so no yɛ nokware, etumi, na ɛho ka yɛ-kɔ soro. Nanso ɛda so ara yɛ akontaabu, ɛnyɛ nkonimdi a ɛda adi pefee ma obiara a ɔwɔ baabiara.
