A fixed array in Nadi produces the most over a year at 17°. The design month for an off-grid system is June: at 31° it makes 4.00 kWh per kWp a day, 8% more than at 17°, and costs 3% 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 720 Wp of panels at 70°, versus 320 Wp at 17°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Nadi compares in Fiji
Against the other 6 places in Fiji with climate data, for a fixed array at its best angle.
2ndof 7 places in Fiji for sunshine: 5.22 peak sun hours a day on flat ground.
+3%solar energy a year compared with the average place in Fiji: 1,567 against 1,514 kWh per kWp.
−1 mindaylight on the longest day, compared with Nasinu: 13 h 12 min against 13 h 13 min.
17°best year-round tilt here; across Fiji it runs from 16° in Nasinu to 17° in Lautoka.
Of the 7 places in Fiji, Lautoka gets the most sun (5.23 peak sun hours a day) and Nasinu the least (4.91); Nadi ranks 2nd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 1.64 kWh a day here, against 1.62 kWh on average in Fiji. The shortest day lasts 11 h 04 min, +1 min compared with Nasinu.
