Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 800 Wp of panels at 70°, versus 290 Wp at 14°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Nioko I compares in Burkina Faso
Against the other 73 places in Burkina Faso with climate data, for a fixed array at its best angle.
27thof 74 places in Burkina Faso for sunshine, shared: 5.84 peak sun hours a day on flat ground.
+1%solar energy a year compared with the average place in Burkina Faso: 1,721 against 1,709 kWh per kWp.
±0 mindaylight on the longest day, compared with Ouagadougou: 12 h 51 min against 12 h 51 min.
14°best year-round tilt here; across Burkina Faso it runs from 11° in Batié to 15° in Ouahigouya.
Of the 74 places in Burkina Faso, Aribinda and one other place get the most sun (6.07 peak sun hours a day) and Batié the least (5.34); Nioko I ranks joint 27th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.47 kWh a day here, against 1.47 kWh on average in Burkina Faso. The shortest day lasts 11 h 24 min, ±0 min compared with Ouagadougou.
