Best solar panel angle in Bouca
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
9°collects the most energy over a year: 1587 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Bouca produces the most over a year at 9°. The design month for an off-grid system is July: at 0° it makes 3.84 kWh per kWp a day, 5% more than at 9°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Bouca at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 9° (year-round best).

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 970 Wp of panels at 70°, versus 320 Wp at 9°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Bouca compares in the Central African Republic
Against the other 32 places in the Central African Republic with climate data, for a fixed array at its best angle.
10thof 33 places in the Central African Republic for sunshine, shared: 5.43 peak sun hours a day on flat ground.
+2%solar energy a year compared with the average place in the Central African Republic: 1,587 against 1,550 kWh per kWp.
+8 mindaylight on the longest day, compared with Bangui: 12 h 30 min against 12 h 23 min.
9°best year-round tilt here; across the Central African Republic it runs from 6° in Bimbo to 12° in Ndélé.
Of the 33 places in the Central African Republic, Ndélé gets the most sun (5.70 peak sun hours a day) and Nola the least (4.89); Bouca ranks joint 10th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.22 kWh a day here, against 1.19 kWh on average in the Central African Republic. The shortest day lasts 11 h 45 min, −7 min compared with Bangui.
