A fixed array in Siguiri produces the most over a year at 13°. The design month for an off-grid system is August: at 0° it makes 4.02 kWh per kWp a day, 3% more than at 13°, and costs 2% 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 840 Wp of panels at 70°, versus 300 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Siguiri compares in Guinea
Against the other 46 places in Guinea with climate data, for a fixed array at its best angle.
2ndof 47 places in Guinea for sunshine: 5.74 peak sun hours a day on flat ground.
+6%solar energy a year compared with the average place in Guinea: 1,692 against 1,594 kWh per kWp.
+7 mindaylight on the longest day, compared with Conakry: 12 h 48 min against 12 h 41 min.
13°best year-round tilt here; across Guinea it runs from 10° in Nzérékoré to 14° in Kintinian.
Of the 47 places in Guinea, Kintinian gets the most sun (5.75 peak sun hours a day) and Nzérékoré the least (4.86); Siguiri ranks 2nd. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.41 kWh a day here, against 1.35 kWh on average in Guinea. The shortest day lasts 11 h 27 min, −7 min compared with Conakry.
