Below is the average daily output per kW of Solar PV installed for each season, along with the ideal solar panel tilt angles calculated for various locations in Kenya. Click on any location for more detailed information.

Explore the solar photovoltaic (PV) potential across 9 locations in Kenya, from Marsabit to Mombasa. We have utilized empirical solar and meteorological data obtained from NASA's POWER API to determine solar PV potential and identify the optimal panel tilt angles for these locations.

Feel free to contact us if you wish for us to include a general Solar PV Analysis for a certain city or location not already listed here for Kenya. We will be more than happy to manually add it for you.

Solar Panel Tilt Angle in Kenya

So far based on Solar PV Analysis of 9 locations in Kenya, we've discovered that the ideal angle to tilt solar PV panels in Kenya varies between 2° from the horizontal plane facing South in Marsabit and 3° from the horizontal plane facing North in Mombasa.

These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).

Depending on where you are based in Kenya, the ideal angle to tilt your solar panels will vary by approx 5 degrees (between 2° from the horizontal plane facing South and 3° from the horizontal plane facing North).

Kenya solar PV Stats as a country

Kenya ranks 77th in the world for cumulative solar PV capacity, with 147 total MW's of solar PV installed. Each year Kenya is generating 3 Watts from solar PV per capita (Kenya ranks 85th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Kenya?

Yes, there are several incentives for businesses wanting to install solar energy in Kenya. These include the Feed-in Tariff (FiT) program, which provides a guaranteed price for electricity generated from renewable sources; the Renewable Energy Fund, which provides grants and loans to support renewable energy projects; and the Solar Home System Program, which offers subsidies for households to purchase solar home systems. Additionally, businesses may be eligible for tax credits or other financial incentives from local governments.
