A fixed array in Wollongong produces the most over a year at 32°. The design month for an off-grid system is June: at 58° it makes 3.49 kWh per kWp a day, 12% more than at 32°, and costs 9% 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 430 Wp of panels at 70°, versus 380 Wp at 32°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
