Best solar panel angle in Geoje
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
32°collects the most energy over a year: 1370 kWh per kWp.
39°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Geoje produces the most over a year at 32°. The design month for an off-grid system is December: at 39° it makes 3.35 kWh per kWp a day, 5% more than at 32°, and costs 1% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 530 Wp of panels at 70°, versus 370 Wp at 32°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
