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 950 Wp of panels at 70°, versus 310 Wp at 12°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

Against the other 74 places in Sudan with climate data, for a fixed array at its best angle.
72ndof 75 places in Sudan for sunshine: 5.88 peak sun hours a day on flat ground.
−9%solar energy a year compared with the average place in Sudan: 1,718 against 1,880 kWh per kWp.
−22 mindaylight on the longest day, compared with Khartoum: 12 h 41 min against 13 h 03 min.
12°best year-round tilt here; across Sudan it runs from 12° in Abyei to 19° in Atbara.
Of the 75 places in Sudan, Mellit gets the most sun (6.72 peak sun hours a day) and Port Sudan the least (5.78); Abyei ranks 72nd. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.24 kWh a day here, against 1.52 kWh on average in Sudan. The shortest day lasts 11 h 34 min, +22 min compared with Khartoum.
