Path-Q Solar

What permit risk exists when a solar project includes structural work beyond panel mounting?

Answer

Structural work beyond ordinary panel mounting may trigger additional building, structural, electrical, fire, planning, or engineering approvals. It can also change the inspection scope and schedule. The permit risk depends on the work, jurisdiction, building type, and whether the design is supported by required calculations.

Key points

  • Examples include roof reinforcement, new support structures, carports, equipment buildings, trenching, and alterations to walls or foundations.
  • The permit package may need structural drawings, load calculations, site plans, and engineering certifications.
  • The contract should identify who designs, submits, pays for, and closes each permit.

What it depends on

  • Scope and location of structural alterations
  • Building and planning requirements
  • Existing structure and site conditions
  • Required engineering and inspection process

Risks and trade-offs

  • Unpermitted structural work can create safety, resale, insurance, and enforcement problems.
  • Discoveries during inspection may require redesign or added construction.
  • Separating structural and solar contractors can create gaps in responsibility.

Information you may need

  • Detailed scope and drawings
  • Structural assessment and engineering requirements
  • Permit checklist from the authority
  • Contract allocation of design, permit, inspection, and correction duties

Your next step

What to do next

Have the project team obtain a written permit-scope determination before construction and include all required structural work in the contract price and schedule.
