A fixed array in Lucapa produces the most over a year at 12°. The design month for an off-grid system is January: at 3° it makes 3.88 kWh per kWp a day, 5% more than at 12°, 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 880 Wp of panels at 70°, versus 320 Wp at 12°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
