Best solar panel angle in Liang
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
3°collects the most energy over a year: 1482 kWh per kWp.
6°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 1,030 Wp of panels at 70°, versus 310 Wp at 3°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
