THE SHORT ANSWER
A preliminary design can organize usage, imagery and equipment assumptions. It cannot replace field measurements, code review, utility approval or qualified electrical and roof assessment.
Use remote review for the right work
A preliminary review can reconcile utility usage, ownership, roof imagery, homeowner goals, possible equipment and an early layout. DOE describes solar projects as involving site, installer, utility and financing considerations. [1] Label the concept with a date and source inputs.
List what remains unverified
Roof condition, structural details, hidden obstructions, attachment substrate, electrical configuration, grounding, conductor paths, equipment clearances and exact dimensions may require site access. The proposal should name these dependencies instead of presenting remote imagery as a completed survey.
Assign qualified decisions
Ask who will evaluate roofing, structural, solar and electrical conditions and who holds responsibility for each regulated scope. Florida DBPR’s official search helps verify applicable contractor credentials. [2] A salesperson’s confidence does not replace the responsible professional’s field determination.
Create revision triggers
Define which findings can change module count, equipment, roof work, electrical scope, price or schedule. Ask how the homeowner receives and approves a revision. A design marked preliminary should not flow into installation after a material change without updated documents.
Preserve the decision trail
Keep submitted photos, usage files, preliminary design, survey report, revised layout and owner approvals. Mark obsolete versions clearly. Origin Direct can make the conversation more transparent, but no remote intake should be presented as utility authorization or a guarantee of project outcome.
Before your next conversation
- Label the preliminary design.
- List field-verification dependencies.
- Identify qualified reviewers.
- Define material revision triggers.
