Solar and backup power in Bungoma
Bungoma, Bungoma County, gets 5.87 peak sun hours a day on average. The dullest month is July at 5.2 hours, 20% less than February, the sunniest at 6.49. That makes it sunnier than 44% of the 26 cities we cover in Kenya.
Sunshine in Bungoma is steady through the year: even July, the dullest month, is within 15% of the yearly average, so a system sized for it is barely bigger than one sized for an average month. Across the year, Bungoma gets about the same sunshine as the average of the cities we cover in Kenya.
What a home in Bungoma needs

Planning tips for Bungoma
- Size panels for July, not for the yearly average. A system sized on the average falls short in the dullest weeks, which is when you most need it.
- Dust, heat and shade cut output. Keep panels clean, leave air space under them, and avoid anything that shades them between mid-morning and mid-afternoon.
- Ask installers for the inverter's continuous and surge ratings, the battery's usable capacity and chemistry, and the panels' total watts. Compare those numbers with your plan rather than the package name.
