Best solar panel angle in Rezh
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
47°collects the most energy over a year: 1105 kWh per kWp.
83°gives the most in the darkest month — the one an off-grid system is sized for.
