A fixed array in Arar produces the most over a year at 27°. The design month for an off-grid system is December: at 45° it makes 4.69 kWh per kWp a day, 12% more than at 27°, and costs 4% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 420 Wp of panels at 70°, versus 280 Wp at 27°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
