Path-Q Solar

When is a solar feasibility study unnecessary for a simple, unshaded roof?

Answer

A separate feasibility study may be unnecessary when the roof is straightforward, structurally sound, unshaded, accessible, and the electrical connection and project goals are clear. In that case, a competent installer may be able to include the necessary site assessment in a quote. A separate study is still useful when roof condition, structural capacity, ownership, electrical complexity, or future loads are uncertain.

Key points

  • Confirm that the roof condition, orientation, access, and shading are genuinely simple rather than assumed.
  • Ensure the installer evaluates structural, electrical, layout, production, and interconnection issues within the proposal.
  • Use a separate study when competing quotes rely on materially different assumptions.
  • Request enough design information to compare proposals even without a standalone report.

What it depends on

  • Roof condition and construction
  • Shading and layout complexity
  • Existing electrical service and planned loads
  • Installer qualifications and assessment scope

Risks and trade-offs

  • Skipping a separate study can save money but leaves more reliance on the installer.
  • A low-complexity roof does not eliminate electrical, structural, or contract risks.
  • A study may be unnecessary for one property but valuable for resolving competing designs.

Information you may need

  • Roof age, condition, and construction details
  • Utility bills and planned loads
  • Electrical equipment photos and site access information
  • What the installer's site assessment includes

Your next step

What to do next

Ask installers to document their included feasibility checks and identify any unresolved assumptions before paying for a separate study.
