Best solar panel angle in Kaédi
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
16°collects the most energy over a year: 1811 kWh per kWp.
17°gives the most in the darkest month — the one an off-grid system is sized for.

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 630 Wp of panels at 70°, versus 250 Wp at 16°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
