6.3 peak sun hours a day
Marsabit receives 6.3 kWh/m² of solar energy a day, so each kilowatt of panels produces roughly 1,796 kWh a year. November is the weakest month; size essential loads to still work then.

Solar power in Marsabit County.
What solar, battery backup and EV charging look like in Marsabit: the county's solar resource month by month, what a typical system produces, local design points for a arid climate, and a calculator using your KPLC bill.
Some of Kenya's strongest sun
Arid counties receive high, steady solar energy, so each panel produces more than in the highlands. Plan the array for the hottest months, when heat derates output.
Plan for cleaning
Dust and sand settle on panels and can cut output noticeably between rains. Budget for regular cleaning and choose a tilt that sheds dust and rain.
Solar first, diesel as backup
Many sites are far from the grid or have weak supply. Solar with batteries or water storage usually costs less per kWh than running a diesel generator.

Long-term average daily solar energy on a horizontal surface and air temperature from NASA POWER, with the output of an example 5 kW system. Near the equator a low-tilt array receives close to the horizontal value.

Frequently asked questions
How much sun does Marsabit get for solar?
Marsabit receives about 6.3 kWh of solar energy per square metre per day on average (6.3 peak sun hours). February is the strongest month at 6.9 and November the weakest at 5.8. Source: NASA POWER long-term modelled data for Marsabit.
How much does a 5 kW solar system produce in Marsabit?
About 8,977 kWh a year, or 24.6 kWh a day on average, assuming a 78% performance ratio for heat, dust, wiring and inverter losses. Output ranges from about 673 kWh in November to 751 kWh in February.
How many solar panels does a home in Marsabit need?
A home using 300 kWh a month with half of it in daylight needs about 1.0 kW of solar for its daytime use, which is 2 panels of 620 W. Covering evening use as well needs a battery and a larger array. Use the calculator on this page with your own bill.
Can StimaPulse plan a solar, battery or EV charging project in Marsabit?
Yes. StimaPulse sizes solar, storage and EV charging for homes, schools, businesses and fleets anywhere in Marsabit County, using your bills or meter data, the site's own solar resource, real equipment and supplier quotes. A licensed engineer must verify the final design before installation.
