Solar Design Kenya
Energy Usage
To choose the right solar system in Kenya, start by understanding your daily electricity consumption. The average household uses around 15 kWh per day, whilst energy efficient properties may use only half that.
Lowering energy usage before solar installation—via improved insulation and efficient appliances—often reduces required system size and enhances financial returns.
Typical energy usage per person per day in Kenya:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 3.9kW solar system would typically cover your average daily electricity consumption. Systems sized between 5.9kW and 7.9kW perform best, accounting for natural fluctuations in solar production.
A 6.6 kW system in Kenya generates approximately 30.5 kWh daily on average, with seasonal variation from 4.42 kWh/kW/day in June to 4.94 kWh/kW/day in March.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Kenya
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Kenya, with 50% still coming from the grid. Adding a 10 kWh battery increases energy independence to approximately 99% annually, reducing grid reliance to 1%.

Solar & Battery System Cost Kenya
Understanding Solar & Battery System Costs
Solar installation costs in Kenya start at approximately KSh666,823 for a 6.6 kW system, with a 10 kWh battery bringing the total to around KSh1,344,841. Payback periods for solar-only installations average approximately 7.0 years, whilst battery storage extends payback but significantly improves energy independence.
The cost breakdown shows estimates for equipment costs, installation labour, and applicable taxes. Adjust system size and battery storage to see how it affects total investment and payback periods.
