A fixed array in Liaocheng produces the most over a year at 33°. The design month for an off-grid system is January: at 45° it makes 3.19 kWh per kWp a day, 7% more than at 33°, and costs 2% 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 520 Wp of panels at 70°, versus 400 Wp at 33°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
