Each county's own solar resource
County pages use NASA POWER long-term modelled solar and temperature data for the county town, so output and sizing reflect local conditions.
Solar by county
Solar, county by county.
Kenya's solar resource changes from the cloudy highlands to the sunny north. Pick your county to see its monthly solar energy, what a typical system produces there, local design points and a calculator using your KPLC bill.
Design points by climate zone
Coastal corrosion, dust in arid areas, rainy-season dips in the highlands and lightning around the lake basin each change how a system should be specified.
Frequently asked questions
Which part of Kenya is best for solar?
Arid and semi-arid northern and eastern counties such as Turkana, Marsabit, Wajir, Garissa and Kitui receive the strongest and steadiest sun. Every county has enough solar energy for practical systems; the highlands and lake basin simply see a deeper dip in the rainy and overcast months.
How many peak sun hours does Kenya get?
Averaged over the year, most of Kenya receives roughly 4.5 to 6.5 kWh per square metre per day, often called peak sun hours, with lower values in the cloudiest months. Each county page lists the monthly values for its county town.
Does solar work during the rainy season?
Yes, at lower output. Panels still produce on cloudy days, and systems are sized on the yearly total with a check that the weakest month still covers essential loads. Batteries or grid supply cover the shortfall.
