Solar Engineering Stamps for PV Permit Drawings
Many authorities having jurisdiction (AHJs) require an engineering stamp on solar permit plan sets. It shows that a licensed engineer has reviewed and approved the solar permit drawings and gives their professional stamp of approval.
The GreenLancer platform has licensed and insured PV engineers in all 50 states who review solar system layouts, electrical diagrams, structural details, solar equipment specifications, and other relevant project data. We deliver residential and commercial solar engineering services with short turnaround times.
Professional Solar Engineering Services for Contractors
It can be time-consuming and costly for solar contractors and developers to obtain PE stamps for permit plan sets. The GreenLancer platform was created to accelerate the adoption of renewable energy by delivering
permit-ready solar design and engineering solutions.

FAQs on our Solar
Engineering Services
What is a solar engineering review?
A solar engineering review is a licensed engineer's evaluation and stamp of approval on a solar permit plan set. It confirms the structural and electrical design meets code requirements before submission to the AHJ.
What does a solar engineering review include?
A review includes a full check of solar permit drawings, structural and electrical calculations, and an engineering seal on the final documents. GreenLancer offers structural, electrical, and civil reviews, including environmental and geotechnical studies when a project requires them.
What is the difference between a wet stamp and a digital stamp?
A wet stamp is a physical ink or embossed seal applied by a licensed engineer, while a digital stamp is an electronic seal with the same legal standing in most jurisdictions. GreenLancer provides both structural and electrical stamps in either format, depending on what your AHJ accepts.
How long does a PE stamp take for a solar project?
Residential projects typically take 1 to 3 business days. Small commercial projects typically take 2 to 5 business days, depending on project complexity.
What states does GreenLancer's engineering service cover?
GreenLancer's network of engineers is licensed and insured in all 50 states. Each project is matched with an engineer licensed in the state where it's located, since PE licensure is state-specific.
Does GreenLancer provide civil engineering reviews?
Yes. In addition to structural and electrical reviews, GreenLancer offers civil reviews, environmental studies, and geotechnical studies for projects that require them.
