A fixed array in Umuarama produces the most over a year at 23°. The design month for an off-grid system is June: at 39° it makes 3.84 kWh per kWp a day, 9% more than at 23°, and costs 3% 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 590 Wp of panels at 70°, versus 340 Wp at 23°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
