A fixed array in Buni produces the most over a year at 32°. The design month for an off-grid system is January: at 56° it makes 3.89 kWh per kWp a day, 13% more than at 32°, and costs 6% 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 350 Wp of panels at 70°, versus 340 Wp at 32°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
