Solar Panel Tilt Calculator

Calculate the optimal tilt angle for your solar panels based on your location and installation preferences to maximize energy production throughout the year.

Your location's latitude (positive for North, negative for South)
How often you plan to adjust the panel tilt
Leave at 0 for ground mount or flat roof
Choose your energy production priority

How to Use This Calculator

  1. Enter Latitude: Input your location's latitude or use the "Get My Location" button.
  2. Select Mount Type: Choose how often you can adjust your panels.
  3. Specify Roof Pitch: Enter your roof angle if mounting on a pitched roof.
  4. Choose Priority: Select whether to optimize for annual, summer, or winter production.

Seasonal Tilt Angles

Winter Latitude + 15° Dec 21

Important Considerations:

  • South-facing orientation is optimal for Northern Hemisphere
  • North-facing orientation is optimal for Southern Hemisphere
  • Consider local weather patterns and shading
  • Account for structural limitations and wind loads
  • Check local regulations and building codes
  • Factor in ease of maintenance and cleaning

For professional installations, consult with a solar expert to verify calculations and consider site-specific factors.
