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 1,160 Wp of panels at 70°, versus 370 Wp at 3°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
