Solar Roof Shading Analysis: Why Your Roof Might Not Qualify

You look at your roof and see nothing but sun. Your neighbor installed panels last year and loves them. You assume your roof is ready.

But 40% of solar site visits end with the installer saying no. The number one reason is shading.

How shading kills solar ROI

Solar panels produce electricity when sunlight hits them directly. Even partial shade on one panel can reduce the output of an entire string. A tree that looks small in winter casts a massive shadow in summer. A chimney, vent pipe, or neighboring building can block critical afternoon sun.

Most homeowners do not realize this until an installer tells them their roof will not produce enough energy to justify the cost.

Seasonal shading is the hidden problem

The shade pattern on your roof changes throughout the year. A tree that clears your roof in January might cover half of it in July. Professional installers use tools like Solar Pathfinder or satellite software to model shade across all four seasons.

You can do this yourself before calling an installer.
