A fixed array in Coxim produces the most over a year at 21°. The design month for an off-grid system is January: at 19° it makes 4.28 kWh per kWp a day, 1% more than at 21°, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Coxim at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 21° (year-round best).

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 700 Wp of panels at 70°, versus 280 Wp at 21°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
