A fixed array in Mar del Plata produces the most over a year at 32°. The design month for an off-grid system is June: at 62° it makes 3.00 kWh per kWp a day, 14% more than at 32°, and costs 12% of the yearly total. Why steep panels win winter.

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 400 Wp of panels at 70°, versus 450 Wp at 32°. The steep array is 12% smaller for the same winter. Size your own system.
