Solar and backup power in Ho
Ho, Volta, gets 4.91 peak sun hours a day on average. The dullest month is August at 4.31 hours, 20% less than April, the sunniest at 5.4. That makes it sunnier than 47% of the 16 cities we cover in Ghana.

Planning tips for Ho
- Size panels for August, 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.
