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 Sachse
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
30°collects the most energy over a year: 1558 kWh per kWp.
48°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Sachse produces the most over a year at 30°. The design month for an off-grid system is December: at 48° it makes 3.80 kWh per kWp a day, 11% more than at 30°, and costs 4% of the yearly total. Why steep panels win winter.
Off-grid solar in Sachse at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 30° (year-round best).

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 460 Wp of panels at 70°, versus 350 Wp at 30°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

30°best year-round tilt here; across the United States it runs from 18° in Honolulu to 53° in Fairbanks.
Of the 3,121 places in the United States, Fortuna Foothills and 2 other places get the most sun (5.96 peak sun hours a day) and Juneau the least (2.38); Sachse ranks joint 1050th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 2.57 kWh a day here, against 2.55 kWh on average in the United States. The shortest day lasts 9 h 58 min, +43 min compared with New York City.
