A fixed array in Taipei produces the most over a year at 18°. The design month for an off-grid system is December: at 45° it makes 2.26 kWh per kWp a day, 10% more than at 18°, and costs 9% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through May on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 650 Wp of panels at 70°, versus 570 Wp at 18°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
