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 Sompeta
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
20°collects the most energy over a year: 1477 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Sompeta produces the most over a year at 20°. The design month for an off-grid system is July: at 0° it makes 3.24 kWh per kWp a day, 7% more than at 20°, and costs 5% of the yearly total. Why steep panels win winter.
Off-grid solar in Sompeta at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 20° (year-round best).

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 780 Wp of panels at 70°, versus 390 Wp at 20°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
