A fixed array in Yangzhou produces the most over a year at 27°. The design month for an off-grid system is November: at 41° it makes 2.55 kWh per kWp a day, 6% more than at 27°, and costs 2% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through September on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 560 Wp of panels at 70°, versus 490 Wp at 27°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
