A fixed array in Tak produces the most over a year at 19°. The design month for an off-grid system is August: at 1° it makes 3.42 kWh per kWp a day, 4% 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 June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 730 Wp of panels at 70°, versus 360 Wp at 19°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
