Path-Q Solar

How many solar panels would fit on my roof without covering shaded areas?

Answer

A reliable panel count requires a dimensioned roof layout that places actual panel rectangles around shaded zones, roof edges, obstructions, access paths, setbacks, and other constraints. Aggregate usable area divided by panel area is only a rough upper bound because irregular geometry and panel orientation can leave unusable spaces.

Key points

  • Exclude persistent shade or model its effect rather than automatically using every roof section.
  • Obstructions and required access paths reduce usable area.
  • Panel dimensions, orientation, and the shape of each roof section matter.

What it depends on

  • Roof measurements and geometry
  • Shade throughout the year
  • Local installation and access requirements

Risks and trade-offs

  • Ignoring shade can overstate production.
  • Fitting more panels may complicate maintenance or increase layout cost.

Information you may need

  • Dimensioned roof plan or measurements
  • Obstruction locations
  • Shade assessment
