A fixed array in Shikang produces the most over a year at 18°. The design month for an off-grid system is January: at 30° it makes 2.52 kWh per kWp a day, 5% more than at 18°, and costs 2% 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 490 Wp at 18°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
