Each column is one day of 2026. Bright: sun above the horizon; soft: civil twilight; line: solar noon. Steps are daylight saving time changes.
Best solar panel angle in Pepa
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
13°collects the most energy over a year: 1637 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Pepa produces the most over a year at 13°. The design month for an off-grid system is December: at 0° it makes 3.77 kWh per kWp a day, 8% more than at 13°, and costs 2% of the yearly total. Why steep panels win winter.
Off-grid solar in Pepa at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 13° (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 950 Wp of panels at 70°, versus 340 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
