Professional Engineering Review Services

Solar project support with electrical & structural reviews, permit stamping, and NEC/IEEE-compliant approvals.

BESS Solutions

At Finulent Solutions, we are experts at providing certified Electrical &, Structural Engineering Review and Stamping Services to facilitate code-compliant, smooth solar PV installations. Whether you are installing a residential, commercial, or utility-scale system, our licensed Professional Engineers (PEs) make sure your electrical designs are energy-efficient, permit-approved, and safe.

We assist your project in every key phase - ranging from pre-construction design verification to post-installation reporting - streamlining AHJ approvals, utility interconnection, and inspection sign-offs.

Structural Engineering Review & Stamping Services

Frequently Asked Questions
What services are included in Finulent's Electrical Engineering Review Services?
Our Electrical Engineering Review Services span from review of inverter sizing, voltage drop calculation, and wiring diagrams to solar grounding and bonding, overcurrent protection, and preparation of NEC 690 compliance reports. We verify your system design follows national and local codes and offer PE-stamped electrical drawings, ready for AHJ and utility approval. Find out more about our solar permit services1 for end-to-end assistance.
Do I require electrical stamping to close solar permit documentation?
If there is a specific requirement, we submit AHJs and utilities PE-stamped documentation to finalize solar permit closure documentation. Our load evaluation, rapid shutdown compliance verification, and NEC Article 6901 and IEEE 15472 grid-tied solar standards labeling stamping services are available.
Do you conduct wind load calculations for solar racking system stability?
Yes. Our team of engineers collaborates with structural PEs to guarantee solar racking system stability, such as wind load calculations for solar installations, according to ASCE solar compliance standards. We confirm rooftop anchoring, mounting integrity, and ballasting for both electrical and structural safety.
How do you provide rapid shutdown compliance and NEC 690 readiness?
Finulent reviews isolate locations, string configurations, and device ratings to be fully NEC 690.12 compliant. We also properly label, ensure bonding continuity, and provide fault protection as required by both NEC and AHJ.
What is contained within a final inspection solar checklist?
Our final inspection solar checklist consists of your post-installation letter, one-line diagrams with solar electrical engineering stamps and solar structural engineering stamps on the structural pages of permit plans, voltage drop and load calculations, rapid shutdown verification, safety documentation, and AHJ-specific requirements. This whole package makes sign-off easy for both inspectors and utilities, supported by our solar-specific expertise.
What is Finulent's approach to as-built solar verification?
We examine installation photos, as-built electrical plans, and last-minute layout modifications to validate field compliance. Our as-built solar verification verifies your system stays on track with the approved engineering design and NEC codes—even with mid-installation changes.
In what ways do Finulent's services assist with grid interconnection approvals?
By synchronizing your electrical design with IEEE 1547, utility regulations (for example, CA Rule 21), and AHJ inspection standards, Finulent provides a seamless route to utility interconnection approval. We also provide all required documents of major utility providers, ranging from overcurrent protection specifications to load impact studies.
