A fixed array in Newala produces the most over a year at 13°. The design month for an off-grid system is January: at 6° it makes 4.16 kWh per kWp a day, 4% more than at 13°, and costs 1% 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 860 Wp of panels at 70°, versus 290 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
