Solar Panel Angle Calculator – Best Tilt for Any Location

What angle should solar panels be at? The best tilt for your location from real weather data (PVGIS), yield per angle and orientation – free.

The best angle for each month in New York

  • The best tilt from five years of hourly weather at your location – with a yield curve, a summer/winter adjustment plan and a month-by-month table.
  • Angle at which the noon sun on the 21st hits a south-facing panel square on:
  • January: 60° · Noon sun height 30°
  • February: 51° · Noon sun height 39°
  • March: 40° · Noon sun height 50°
  • April: 29° · Noon sun height 61°
  • May: 20° · Noon sun height 70°
  • June: 17° · Noon sun height 73°
  • July: 20° · Noon sun height 70°
  • August: 29° · Noon sun height 61°
  • September: 40° · Noon sun height 50°
  • October: 52° · Noon sun height 38°
  • November: 61° · Noon sun height 29°
  • December: 64° · Noon sun height 26°

Is adjusting the angle worth it?

Computed from the weather data – plus the angle at which the noon sun on the 21st hits the panel square on.

The best angle is usually flatter than the angle facing the noon sun: under clouds much of the light comes diffusely from above.
