Solar Panel Spacing Calculator

Calculate the optimal spacing between rows of solar panels to minimize inter-row shading and maximize energy production throughout the year.

Your location's latitude (positive for North, negative for South)
Typical residential panel length is 65-67 inches
Typical residential panel width is 39-40 inches
Panel tilt angle from horizontal
Acceptable shading during winter solstice
Minimum height from ground to panel edge

How to Use This Calculator

  1. Enter Location: Input your latitude or use the "Get My Location" button.
  2. Panel Dimensions: Enter the length and width of your solar panels.
  3. Tilt Angle: Specify the angle at which panels will be mounted.
  4. Shading Tolerance: Choose acceptable shading during winter solstice.
  5. Ground Clearance: Set minimum height from ground to panel edge.

Understanding the Results

  • Minimum Row Spacing: Absolute minimum distance between panel rows to meet shading requirements.
  • Recommended Spacing: Optimal distance including safety margin and maintenance access.
  • Ground Coverage Ratio: Percentage of available ground area covered by panels.

Important Considerations:

  • Local building codes may require specific minimum spacing
  • Consider maintenance access requirements
  • Account for site-specific obstacles and shading
  • Snow accumulation may require additional spacing
  • Wind loads may affect minimum spacing requirements
  • Roof installations may have different spacing needs

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