A fixed array in Taichung produces the most over a year at 19°. The design month for an off-grid system is December: at 42° it makes 2.98 kWh per kWp a day, 10% more than at 19°, and costs 6% 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 630 Wp of panels at 70°, versus 430 Wp at 19°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
