Best solar panel angle in Daru
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
8°collects the most energy over a year: 1447 kWh per kWp.
26°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Daru produces the most over a year at 8°. The design month for an off-grid system is June: at 26° it makes 3.54 kWh per kWp a day, 8% more than at 8°, and costs 4% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 930 Wp of panels at 70°, versus 360 Wp at 8°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Daru compares in Papua New Guinea
Against the other 12 places in Papua New Guinea with climate data, for a fixed array at its best angle.
2ndof 13 places in Papua New Guinea for sunshine: 4.98 peak sun hours a day on flat ground.
+2%solar energy a year compared with the average place in Papua New Guinea: 1,447 against 1,414 kWh per kWp.
−1 mindaylight on the longest day, compared with Port Moresby: 12 h 39 min against 12 h 41 min.
8°best year-round tilt here; across Papua New Guinea it runs from 4° in Kokopo to 8° in Port Moresby.
Of the 13 places in Papua New Guinea, Port Moresby gets the most sun (5.24 peak sun hours a day) and Lae the least (4.59); Daru ranks 2nd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 1.27 kWh a day here, against 1.22 kWh on average in Papua New Guinea. The shortest day lasts 11 h 36 min, +1 min compared with Port Moresby.
