Solar Energy Guide for Zambia
With frequent load-shedding, solar is increasingly essential in Zambia. This guide covers system sizing, costs, batteries, and whether solar is worth it for you.

Key Decisions
Lead-acid vs Lithium Batteries
- Lead-acid: Cheaper upfront (ZMK 1,500-3,000), but lasts 2-4 years, heavier, only 50% usable capacity.
- Lithium (LiFePO4): More expensive (ZMK 5,000-15,000), but lasts 8-10 years, 80-90% usable, lighter.
Grid-tied vs Off-grid vs Hybrid
- Off-grid: Complete independence from ZESCO. Needs larger battery bank.
- Hybrid: Uses solar when available, ZESCO as backup. Most practical for urban areas.
- Grid-tied: Sells excess to ZESCO (net metering). Regulations still limited in Zambia.
Trusted Installers
Look for ERB-licensed (Energy Regulation Board) installers. Major suppliers include SolarAfrica, Engie Zambia, and Standard Microgrid. Always get 3 quotes minimum.
