A fixed array in Rehoboth produces the most over a year at 25°. The design month for an off-grid system is January: at 25° it makes 5.46 kWh per kWp a day, 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 570 Wp of panels at 70°, versus 220 Wp at 25°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
