Best solar panel angle in Tobelo
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
1°collects the most energy over a year: 1528 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Tobelo produces the most over a year at 1°. The design month for an off-grid system is June: at 0° it makes 3.80 kWh per kWp a day, and costs 0% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through May on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 1,210 Wp of panels at 70°, versus 310 Wp at 1°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
