Solar and backup power in Bannu
Bannu, Khyber Pakhtunkhwa, gets 5.15 peak sun hours a day on average. The dullest month is December at 3.13 hours, 56% less than May, the sunniest at 7.13. That makes it sunnier than 54% of the 25 cities we cover in Pakistan.
Sunshine in Bannu is clearly below its yearly average for 4 months, from November to February. That stretch decides how many panels you need if solar has to keep up all year. Across the year, Bannu gets about the same sunshine as the average of the cities we cover in Pakistan.
What a home in Bannu needs

Planning tips for Bannu
- Size panels for December, 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.
