A fixed array in Nguruka produces the most over a year at 9°. The design month for an off-grid system is December: at 0° it makes 4.01 kWh per kWp a day, 6% more than at 9°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Nguruka at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 9° (year-round best).

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 970 Wp of panels at 70°, versus 310 Wp at 9°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
