Best solar panel angle in Yerevan
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
34°collects the most energy over a year: 1532 kWh per kWp.
66°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 390 Wp of panels at 70°, versus 450 Wp at 34°. The steep array is 13% smaller for the same winter. Size your own system.
