Reports and Inspections

Solar Inspections & IE Reports

Avila Solar Drafting carries out solar inspections and writes independent engineer (IE) reports and cost study reports. The work comes from the same company that drafts, engineers and commissions PV systems, so findings are written in terms a designer, installer or lender can act on. Each report is scoped to the question it has to answer. Request a quote with your project details.

Who uses a solar inspection or IE report?

Lenders, investors, buyers and owners use an independent engineer's review when they need an opinion on a PV system that does not come from the installer. Installers and O&M providers use inspections to check a system before they take responsibility for it.

Where a licensed engineer's sign-off is needed, our PE engineering stamps service and the guide to when a solar project needs a PE stamp explain what a stamp adds.

Services

What reports and inspections does Avila Solar provide?

Independent Engineer (IE) Reports

A third-party engineering review of a PV system for an owner, lender or investor. Scope, site visit and deliverables are set in the quote.

Cost Study Reports

A written cost study for a PV project, scoped to the decision it needs to support.

Field Inspections

On-site inspection of an installed PV system, carried out directly by Avila Solar's own team.

Test Data

Where the scope calls for it, an inspection can include tests Avila Solar runs in commissioning, such as I-V curve tracing up to 1500 Vdc and thermal imaging.

How does a solar inspection or report project work?

  1. Send the system details and tell us who the report is for and what it has to answer.
  2. Avila Solar confirms the scope, site access and deliverables in a written quote.
  3. The site inspection and any testing take place, where the scope includes them.
  4. Avila Solar delivers the written report.

The international standard IEC 62446-1 describes the documentation, commissioning tests and inspection criteria for grid-connected PV systems, and the same criteria can be used when a system is re-inspected later.

What drives the cost of a solar inspection or report?

System size, system type, site location and access, whether a site visit is needed, which tests are included and who the report is written for all change the scope. Avila Solar quotes each project rather than publishing a flat price.

If the question is expected output rather than condition, a solar production report may answer it, and our article on shade reports versus energy models explains the difference. If you need advice rather than a written report, a technical solar consultation may be the better fit. For a new system, start with solar commissioning.

Frequently asked questions

What is an independent engineer (IE) report for a solar project?

An independent engineer (IE) report is a third-party engineering review of a PV system, usually requested by a lender, investor or buyer who needs an opinion that does not come from the installer. Avila Solar scopes each IE report to the questions its reader needs answered.

Does Avila Solar carry out the field inspection itself?

Yes. Avila Solar performs solar inspection work directly with its own team rather than handing the site visit to another firm.

How much does a solar inspection or IE report cost?

Avila Solar quotes solar inspections, IE reports and cost study reports per project, because system size, location, site access, testing and the report's purpose all change the work. Send your project details through the quote form or call 971-410-0655.

Can a solar inspection include I-V curve tracing or thermal imaging?

Avila Solar runs I-V curve tracing up to 1500 Vdc and thermal imaging in its commissioning work, and can include them in an inspection scope when the project calls for them.
