A fixed array in Kassala produces the most over a year at 17°. The design month for an off-grid system is July: at 8° it makes 4.86 kWh per kWp a day, 5% more than at 17°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Kassala at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 17° (year-round best).

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 720 Wp of panels at 70°, versus 260 Wp at 17°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
