Structural & electrical certifications for PV installations nationwide.
We are dedicated to helping businesses get their projects through permitting as quickly as possible - without sacrificing safety or taking other shortcuts. Trust us for expert guidance and reliable solar structural certifications to ensure the success and compliance of your projects.
From single-family rooftops to utility-scale solar farms, we certify projects at every scale.
Fast, reliable PV Letters for residential rooftop installations. Over 50,000 projects completed with typical 1-day turnaround.
Structural analysis and PE-stamped certifications for rooftop arrays on warehouses, offices, retail, and industrial buildings.
Foundation design, pile load analysis, and structural engineering for ground-mount systems and tracker installations at MW scale.
Developed from decades of experience and hundreds of satisfied clients.
You provide us with the project plans and site survey results: photos of the roof internal structure, measurements of the structural members, general photos of the building and the roof itself.
We review the received information and follow up with questions, if any. Otherwise, we start working on the analysis for the project and preparing your documents.
We complete the analysis and provide you with stamped plans and a PV Letter within 36 hours. In some rare cases, we may return to you with recommendations for a roof structure repair or a minor re-design of the solar panel array.
One partner for the full path, from array layout to an approved permit.
PE-stamped structural and electrical analysis for every mounting type and roof condition, sealed by a licensed Professional Engineer in your project's state.
Array layout, attachment and racking design, and complete plan sets built to your installer's specs and the local jurisdiction's requirements.
Full permit packages and hands-on AHJ coordination. We resolve plan-review comments directly so your project keeps moving.
