A fixed array in Hpa-An produces the most over a year at 22°. The design month for an off-grid system is July: at 1° it makes 2.88 kWh per kWp a day, 8% more than at 22°, and costs 5% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 850 Wp of panels at 70°, versus 440 Wp at 22°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
