Best solar panel angle in Khartoum
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
17°collects the most energy over a year: 1957 kWh per kWp.
7°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Khartoum produces the most over a year at 17°. The design month for an off-grid system is August: at 7° it makes 4.93 kWh per kWp a day, 4% more than at 17°, and costs 1% of the yearly total. Why steep panels win winter.

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 720 Wp of panels at 70°, versus 250 Wp at 17°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Khartoum compares in Sudan
Against the other 74 places in Sudan with climate data, for a fixed array at its best angle.
13thof 75 places in Sudan for sunshine: 6.61 peak sun hours a day on flat ground.
+4%solar energy a year compared with the average place in Sudan: 1,958 against 1,880 kWh per kWp.
+6 mindaylight on the longest day, compared with the average place in Sudan: 13 h 03 min against 12 h 58 min.
17°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); Khartoum ranks 13th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.64 kWh a day here, against 1.52 kWh on average in Sudan. The shortest day lasts 11 h 12 min, −5 min compared with the average.
