A fixed array in Geraldton produces the most over a year at 26°. The design month for an off-grid system is June: at 50° it makes 4.33 kWh per kWp a day, 14% more than at 26°, and costs 8% 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 450 Wp of panels at 70°, versus 310 Wp at 26°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
