Best solar panel angle in Ojinaga
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
29°collects the most energy over a year: 1912 kWh per kWp.
30°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Ojinaga produces the most over a year at 29°. The design month for an off-grid system is December: at 30° it makes 4.82 kWh per kWp a day, and costs 0% 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 490 Wp of panels at 70°, versus 250 Wp at 29°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
