A fixed array in Sanchazi produces the most over a year at 42°. The design month for an off-grid system is December: at 46° it makes 3.40 kWh per kWp a day, 3% more than at 42°, and costs 0% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 460 Wp of panels at 70°, versus 360 Wp at 42°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
