Keep model numbers consistent
Compare the quotation, delivered equipment labels and handover inventory. A brochure for a different model is not evidence for the installed equipment.

Compare roof attachments, corrosion protection and electrical commissioning records. A panel warranty alone does not establish installation quality.
Mirasol guide · Updated
For a coastal roof, ask the designer to document the site exposure, mounting choice and maintenance requirements. A module’s warranty does not cover every roof penetration, connection or workmanship issue.
| Part | Useful evidence |
|---|---|
| Roof attachment | Site-specific structural basis and fixing details. |
| Waterproofing | Penetration detail and written responsibility for leaks. |
| Exposed hardware | Manufacturer material and exposure specifications. |
| Electrical work | Single-line diagram, equipment list and test record. |
Ask what component was tested, which document applies to the supplied model and what installation conditions the manufacturer requires. A module test cannot substitute for the structural design of the complete roof system.
Compare the quotation, delivered equipment labels and handover inventory. A brochure for a different model is not evidence for the installed equipment.
Keep configuration records, photographs of completed work, safety labels, commissioning results and the responsible installer’s contact information.
Ask who diagnoses a fault, who removes and reinstalls equipment, which travel or labor costs are excluded and how to report roof leaks. Get the maintenance schedule and the process for checking output after a storm. Qualified professionals must specify and inspect the work.
Track approval and handover documents separately.
Specify backup equipment and tested circuits if storage is included.
Check the sizing inputs behind a DAC proposal before judging the equipment and installation scope.
FAQ
Check the separate manufacturer, workmanship and roof terms. Their coverage and exclusions can differ; obtain the actual documents.
No. It helps screen area and solar potential, but does not establish structural capacity, roof condition or safe fixing details.
The equipment inventory, drawings, commissioning record, warranty documents, operating instructions and monitoring access under your control.

Use your CFE bill for an initial assessment. Roof conditions, equipment and the final scope need confirmation before installation.
