A fixed array in Holguín produces the most over a year at 20°. The design month for an off-grid system is November: at 27° it makes 4.14 kWh per kWp a day, 4% more than at 20°, and costs 1% 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 640 Wp of panels at 70°, versus 300 Wp at 20°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
