A fixed array in Colón produces the most over a year at 28°. The design month for an off-grid system is June: at 58° it makes 3.43 kWh per kWp a day, 14% more than at 28°, and costs 12% 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 450 Wp of panels at 70°, versus 390 Wp at 28°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
