Solar & Battery Design Tools for Kenya Design Systems, Calculate ROI & Find Installers

Design solar and battery systems across Kenya using Photonik's professional design platform. Kenya is a leader in solar adoption across East Africa, with excellent year-round sunshine and a growing network of qualified installers. Rising electricity tariffs and the desire for energy independence are driving more Kenyan homeowners to invest in rooftop solar.

Energy Usage

Properties in Kenya average around 8 kWh daily electricity consumption — and with electricity costs continuing to rise, solar can make a real difference to household budgets. Most households in Kenya use around 8 kWh per day, whilst energy efficient homes can reduce this to roughly half.

Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.

Typical energy usage per person per day in Kenya:

Low (Efficient)
~3 kWh
Medium (average)
~4 kWh
High (intensive)
~6+ kWh

Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.

Solar System Sizing

A solar system sized at approximately 2.1kW would cover your typical daily energy needs. A system in the 3.2kW to 4.2kW range also gives you headroom if your energy needs grow — from a new EV, heat pump, or home office.

Expect around 14.8 kWh daily from a 3.2 kW system in Kenya, with production varying from 4.42 kWh/kW/day in June to 4.94 kWh/kW/day in March.

A 4 kW system in Kenya can generate approximately 6753.0 kWh annually based on local sun conditions.

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.

Calculate Electrification Savings

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

Even without a battery, 50% self-sufficiency from a 3.2 kW system in Kenya means a significant reduction in your electricity bills. The jump from 50% to 99% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.

To get precise battery savings and payback figures, use the complete Photonik design platform.

0 kWh 30 kWh

lightbulb A 0kWh battery will make you about 0% self sufficient.

The sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.

Solar & Battery System Cost Kenya

Understanding Solar & Battery System Costs

The typical investment for solar in Kenya is approximately KSh369,757 for 3.2 kW, with the option to add a 10 kWh battery for around KSh1,079,311 total. Solar-only systems typically pay for themselves in around 7.9 years, whilst adding battery storage usually extends payback whilst increasing energy independence.

The pricing breakdown includes equipment, installation labour, and applicable taxes. Use the sliders to adjust system size and battery capacity to see how pricing and payback change.
