Best solar panel angle in Haenam
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
30°collects the most energy over a year: 1317 kWh per kWp.
50°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Haenam produces the most over a year at 30°. The design month for an off-grid system is December: at 50° it makes 2.89 kWh per kWp a day, 10% more than at 30°, and costs 5% 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 550 Wp of panels at 70°, versus 450 Wp at 30°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
