Solar vs ZESA Load Shedding: Is Solar Worth It in Zimbabwe?
Short answer: solar is usually the better long-term investment than relying on ZESA or generators during load shedding, especially if you want stable power without fuel costs. The upfront cost is higher, but daily running costs are much lower and most households recover the investment within a few years.
Why households compare solar and generators
Load shedding has made backup power a necessity rather than a luxury for most Zimbabwean households and businesses. The two main alternatives are diesel or petrol generators and solar power with battery storage. Here's an honest comparison from the perspective of a real installation company, ProExpert Solar.
Generators: low upfront cost, high ongoing cost
A generator is cheaper to buy but the ongoing fuel cost adds up fast, especially with load shedding schedules running 8-12 hours a day. Generators are also noisy, need regular servicing, and don't work well for silent overnight backup.
Solar: higher upfront cost, near-zero running cost
A solar and battery system costs more to install but produces free electricity for 20+ years, with batteries lasting 10-15 years. Once installed, there's no fuel to buy and very little maintenance. For homes in Harare and Bulawayo, this makes solar a safer and more predictable energy solution.
Typical payback period
Most of our residential clients in Harare and Bulawayo recover their solar investment within three to five years when comparing it to their previous generator fuel and ZESA top-up spend. After that, the power is essentially free — see our cost breakdown guide for upfront pricing by system size.
Which suburbs benefit most
Areas that experience longer load shedding blocks — common across much of Harare and Bulawayo including suburbs like Khumalo, Hillside, Burnside and Morningside — see the fastest payback, since solar directly replaces the costliest hours of generator use.

Our verdict
For any household or business that experiences regular load shedding, solar is the better long-term investment. Generators still have a role as a small backup for solar systems, but they should not be relied on as the primary power source.
