A fixed array in Kasempa produces the most over a year at 19°. The design month for an off-grid system is December: at 1° it makes 4.36 kWh per kWp a day, 11% more than at 19°, and costs 4% 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 750 Wp of panels at 70°, versus 300 Wp at 19°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
