A fixed array in Owando produces the most over a year at 1°. The design month for an off-grid system is July: at 12° it makes 3.46 kWh per kWp a day, 4% more than at 1°, and costs 2% of the yearly total. Why steep panels win winter.
Off-grid solar in Owando at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 1° (year-round best).

Sizing example. To run a 1 kWh-per-day load through November on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 1,040 Wp of panels at 70°, versus 350 Wp at 1°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
