A fixed array in Vilankulo produces the most over a year at 22°. The design month for an off-grid system is June: at 31° it makes 4.30 kWh per kWp a day, 6% more than at 22°, and costs 1% of the yearly total. Why steep panels win winter.

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 610 Wp of panels at 70°, versus 290 Wp at 22°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
