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 Sinop
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
17°collects the most energy over a year: 1597 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Sinop produces the most over a year at 17°. The design month for an off-grid system is December: at 0° it makes 4.13 kWh per kWp a day, 10% more than at 17°, and costs 3% of the yearly total. Why steep panels win winter.
Off-grid solar in Sinop at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 17° (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 850 Wp of panels at 70°, versus 310 Wp at 17°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
