SEI Engineering Case Study: Edenton Solar – 7.5MW Solar PV System Edenton, North Carolina

By Kyra Holt – SEIPS Director of Engineering

Project Summary:

The harsh and wet environmental conditions of this coastal site, located near the North Carolina Albermarle Sound, was a challenge. Our engineering team worked closely with the developer, civil engineer, and installation team throughout the entire project to create a solid design able to stand up to the test.

Design Highlights:

  • The layout was split between two arrays to avoid multiple existing drainage ditches needed to help control water on the site.
  • Electrical equipment selection and placement was designed to accommodate the future addition of an energy storage system.
  • Elevated equipment skids were used to raise equipment above potential flood waters.
  • This project was a continuation of a long partnership with O2 emc in which SEI Engineering has been the engineer of record for five other solar projects of similar size.

SEI Engineering provided the full electrical design (PV system, auxiliary power, medium voltage design) and the structural design (inverter group structures, equipment pads). SEI Engineering also served as the Design Project Manager tasked with coordinating all contractors involved in the design phase, including civil, surveyor, and equipment manufacturers.
