Escape load shedding with solar + battery for your home
Why go solar + battery in Zambia?
Zambia is facing one of the most severe energy crises in its history. Hydropower — the source of over 80% of the country's electricity — has been crippled by drought, leading to rolling blackouts of 8-12 hours daily across Lusaka and the Copperbelt. Businesses are shutting down, and households are spending a fortune on emergency power sources just to keep the lights on.
At ZK 0.6/kWh (~$0.023 USD), ZESCO's official residential tariff is among the cheapest in the world — but this number is misleading. The real cost of electricity includes generator fuel, inverter batteries charged from the grid, and lost productivity during outages. A solar + battery system eliminates this hidden cost entirely, providing reliable power regardless of what happens with ZESCO or the water levels at Kariba Dam.
Key advantage: Zambia receives 5.0 kWh/m² of daily solar energy — putting it in the same league as South Africa and Australia for solar potential. The drought that crippled hydropower doesn't affect solar panels. Pair solar with battery storage and you have a power source that works every day, rain or shine, drought or flood.

Why Zambians are switching
- ✓ 8-12 hours of daily load shedding makes solar + battery a necessity, not a luxury
- ✓ Drought-proof — unlike hydropower, solar panels work regardless of rainfall
- ✓ ZESCO tariffs will inevitably rise — lock in your energy cost with solar
- ✓ Strong installer network in Lusaka, Kitwe, and Ndola
Things to consider
- ⚠ Low official tariffs mean the financial payback from bill savings alone is slower
- ⚠ The real value is reliability — avoiding generator fuel and lost productivity
- ⚠ Import duties on solar equipment may apply — check current regulations
- ⚠ Size your battery for the full outage duration, not just partial backup
