Best solar panel angle in Suva
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
16°collects the most energy over a year: 1477 kWh per kWp.
35°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Suva produces the most over a year at 16°. The design month for an off-grid system is June: at 35° it makes 3.60 kWh per kWp a day, 10% more than at 16°, 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 720 Wp of panels at 70°, versus 360 Wp at 16°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Suva compares in Fiji
Against the other 6 places in Fiji with climate data, for a fixed array at its best angle.
5thof 7 places in Fiji for sunshine, shared: 4.93 peak sun hours a day on flat ground.
−2%solar energy a year compared with the average place in Fiji: 1,477 against 1,514 kWh per kWp.
±0 mindaylight on the longest day, compared with Nasinu: 13 h 13 min against 13 h 13 min.
16°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); Suva ranks joint 5th. 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 02 min, ±0 min compared with Nasinu.
