Solar and backup power in Mongu
Mongu, Western Province, gets 5.86 peak sun hours a day on average. The dullest month is June at 5.21 hours, 21% less than October, the sunniest at 6.62. That makes it sunnier than 80% of the 16 cities we cover in Zambia.
Sunshine in Mongu is steady through the year: even June, 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, Mongu gets about the same sunshine as the average of the cities we cover in Zambia.
What a home in Mongu needs
Three example homes, each covering a 12-hour daily outage with a lithium battery and solar panels to recharge it. Panels are 450 W. The month-with-least-sun figure is what keeps you covered all year.

Planning tips for Mongu
- Size panels for June, 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.
