A fixed array in East Ridge produces the most over a year at 31°. The design month for an off-grid system is December: at 60° it makes 3.19 kWh per kWp a day, 13% more than at 31°, and costs 11% 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 440 Wp of panels at 70°, versus 420 Wp at 31°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
