Best solar panel angle in Koszalin
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
40°collects the most energy over a year: 1074 kWh per kWp.
73°gives the most in the darkest month — the one an off-grid system is sized for.
