A fixed array in Qinnan produces the most over a year at 29°. The design month for an off-grid system is December: at 46° it makes 3.00 kWh per kWp a day, 9% more than at 29°, and costs 3% 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 560 Wp of panels at 70°, versus 430 Wp at 29°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
