Solar Site Assessment
Field verification of roof, structural, and electrical conditions, so the design and permit package reflect what’s actually at the site — not just the plan.
Who this service is for
- Installers who want field-verified conditions before finalizing a design
- EPCs standardizing a site-survey process across project managers
- Contractors handling older properties or non-standard roof/electrical conditions
What's included
Roof & mounting review
Roof type, condition, and available mounting area evaluated for the proposed array.
Structural spot-checks
Rafter size and spacing, and general structural condition, documented for engineering review.
Electrical panel review
Main service panel bus rating, breaker configuration, and location documented.
Photo documentation
Site photos captured to support the design and permit package.
How solar site assessment works
1. Schedule assessment
Site details and access information are confirmed ahead of the visit.
2. Field verification
Roof, structural, and electrical conditions are documented on site.
3. Documentation compiled
Findings and photos are compiled into a site report.
4. Handed to design/engineering
Verified conditions feed directly into design and structural/electrical calculations.
Information we'll need
Have this ready when you submit a design request:
- Project address and site access details
- Point of contact at the site
- Any known roof or structural concerns
- Existing utility bill, if available
Deliverables
What you'll receive back:
- Site condition report
- Photo documentation of roof, mounting area, and electrical panel
- Structural notes for engineering review
- Confirmed inputs for the design and permit package
Verify site conditions before you design
Request a site assessment as part of your design request, or on its own for an existing project.
Solar Site Assessment — frequently asked questions
A site assessment confirms that field conditions — roof structure, mounting area, panel capacity — match what the design assumes, which reduces the chance of costly changes during installation or permit review.
Yes. While it’s often paired with a design request, you can request a site assessment independently through the same project intake form.
That’s exactly what the assessment is for — documenting non-standard conditions (older panels, unusual roof framing, limited mounting area) so the design and structural engineering account for them from the start.
