A fixed array in Chaupimarca produces the most over a year at 15°. The design month for an off-grid system is February: at 7° it makes 3.74 kWh per kWp a day, 3% more than at 15°, 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 790 Wp of panels at 70°, versus 320 Wp at 15°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
