A fixed array in Assis produces the most over a year at 24°. The design month for an off-grid system is June: at 28° it makes 4.12 kWh per kWp a day, 3% more than at 24°, and costs 0% 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 600 Wp of panels at 70°, versus 290 Wp at 24°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
