Best solar panel angle in Ampahana
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
13°collects the most energy over a year: 1574 kWh per kWp.
30°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 December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 790 Wp of panels at 70°, versus 330 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
