Best solar panel angle in Esquina
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
27°collects the most energy over a year: 1598 kWh per kWp.
54°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Esquina produces the most over a year at 27°. The design month for an off-grid system is June: at 54° it makes 3.50 kWh per kWp a day, 13% more than at 27°, and costs 10% of the yearly total. Why steep panels win winter.
Off-grid solar in Esquina at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 27° (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 490 Wp of panels at 70°, versus 380 Wp at 27°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
