Uganda Solar Battery Calculator
Turn Uganda's equatorial sun into reliable home power
Why go solar + battery in Uganda?
Uganda has some of the highest electricity tariffs in East Africa relative to income levels. UMEME, the main power distributor, charges around USh 650/kWh (~$0.171 USD) — and prices have been climbing year after year. For a typical Kampala household spending USh 150,000-300,000 monthly on electricity, the savings from solar can be transformative.
Located on the equator, Uganda receives 4.9 kWh/m² of daily solar irradiance — more than enough to power a home. The country also has abundant hydroelectric capacity (including the new Karuma dam), but transmission losses and distribution inefficiencies mean end-users still face high bills and occasional outages. Battery storage lets you capture cheap solar energy during the day and use it during expensive evening peak hours.
Key advantage: Uganda has a growing middle class and a strong entrepreneurial culture. Many small businesses — from salons to restaurants — already use solar to reduce operating costs. Home battery systems are the natural next step for residential users who want the same benefits.

Why Ugandans are switching
- ✓ UMEME bills are among the highest in East Africa — solar cuts this drastically
- ✓ Equatorial location means consistent sun year-round — no seasonal surprises
- ✓ Strong mobile money ecosystem makes equipment financing more accessible
- ✓ Growing solar installer market in Kampala, Jinja, and Mbarara
Things to consider
- ⚠ No net metering yet — size your battery to capture all your solar
- ⚠ Quality varies among importers — choose equipment with local warranty support
- ⚠ Consider a hybrid inverter that can switch between solar, battery, and grid
- ⚠ Upfront cost is the main barrier — but payback is typically 3-5 years
