A fixed array in Huaquillas produces the most over a year at 3°. The design month for an off-grid system is July: at 11° it makes 3.54 kWh per kWp a day, 4% more than at 3°, 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 1,110 Wp of panels at 70°, versus 350 Wp at 3°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
