A fixed array in Wucheng produces the most over a year at 26°. The design month for an off-grid system is January: at 44° it makes 2.55 kWh per kWp a day, 7% more than at 26°, and costs 4% 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 680 Wp of panels at 70°, versus 500 Wp at 26°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
