A fixed array in Aketi produces the most over a year at 4°. The design month for an off-grid system is July: at 0° it makes 3.58 kWh per kWp a day, 2% more than at 4°, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Aketi at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 4° (year-round best).

Sizing example. To run a 1 kWh-per-day load through May on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 1,030 Wp of panels at 70°, versus 340 Wp at 4°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
