With electricity costs rising and load shedding affecting parts of Rwanda, more homeowners and businesses in Kigali are asking the same question: is solar worth the investment? Here is our honest, number-based answer.
What Does a System Cost?
A basic residential system (1–2kW with battery storage) in Kigali typically costs between 1,500,000 and 3,500,000 RWF installed. A larger home or business system (3–5kW) runs 4,000,000–8,000,000 RWF depending on battery capacity and panel quality.
Key fact: Kigali averages 5–6 peak sun hours per day — among the best in East Africa — making solar return on investment significantly better than in Europe or northern countries.
How Long to Break Even?
For a typical Kigali household spending 80,000–120,000 RWF per month on electricity, a well-sized solar system typically pays for itself within 3–5 years. After that, your electricity is essentially free for the remaining 15–20 year lifespan of the panels.
