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 Chisec
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
15°collects the most energy over a year: 1468 kWh per kWp.
22°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Chisec produces the most over a year at 15°. The design month for an off-grid system is November: at 22° it makes 3.67 kWh per kWp a day, 3% more than at 15°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Chisec at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 15° (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 800 Wp of panels at 70°, versus 330 Wp at 15°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
