We are very pleased with the excellent service provided by Mayfield Renewables. Their expertise in designing solar PV systems, solar plus storage microgrids, and assisting with microgrid feasibility studies has been invaluable to our projects. The team’s professionalism, attention to detail, and inovative solutions have consistently exceeded expectations and has aided many of our successful grant applications.
We’ve enjoyed working with Mayfield in every respect, and have done so for a long time because of the depth of knowledge they bring, their willingness to engage in conceptual design discussion, and their rapid turnaround when it’s time to do drawings. They’re not just an outsourced engineering firm; they’re a reliable partner that can help avoid the many pitfalls of microgrid implementation.
Attending the Mayfield Renewables Education Summit provided me with what I had hoped for. The technical depth and pace of the sessions were great, with each instructor breaking complex code and energy storage topics into approachable segments while adding big-picture industry insights along the way. Highly recommended for ayone trying to strengthen their grasp on code and requirements within the energy storage field!
Working with the Mayfield engineering team has been an awesome experience. Their team is professional, knowledgeable, and dedicated to quality. They communicate proactively and integrate seamlessly with our processes, ensuring our projects are completed on time and to the highest standards.
The Mayfield Renewables Education Summit was well organized and an impressive inaugural event. Sessions and presentations were led by highly technical solar veterans — a great event for renewable energy training.
Why Mayfield Renewables?
Projects shouldn’t have to sacrifice cutting-edge solutions due to a lack of code expertise or stakeholder misalignment.

A Community-Driven Island Microgrid
One of the northernmost parts of the continental U.S., Orcas Island is roughly three hours (by car and ferry) from downtown Seattle and is connected to the mainland by a single undersea transmission line. Extreme weather events and grid outages can leave locals stranded for extended periods of time. To protect their uniquely vulnerable infrastructure, the San Juan County Emergency Management (SJCEM) agency identified the Orcas Center as a facility that could function as a resiliency hub in an emergency. The location was conveniently central and well known community gathering place. The issue, however, was that the Orcas Center did not have the energy resources required to function as an island-able microgrid system. With a site (Orcas Center) and primary goal (energy resilience) in mind, SJCEM set out to find the right mix of distributed energy resources to achieve key performance benchmarks while staying within space and budgetary constraints. In other words, this island facility was interested in “islanding” from the grid.

The Cost of Complexity: Why the C&I Multi-DER Market Demands a Development Standard
The commercial and industrial (C&I) renewable energy sector is experiencing a paradox. Driven by data center load growth, grid capacity constraints, and community resilience targets, the demand for distributed energy resources (DERs) is at the front end of a significant upward trajectory. Yet, the C&I mid-market lacks a widely accepted industry playbook to develop these […]

When Does a Renewable Energy Project Need Owner’s Engineering Support?
Introduction Understanding what Owner's Engineering is only answers half the question. The harder part for a system owner is knowing exactly when to bring that expertise into a project. Renewable energy assets are built to perform for 25 to 30 years, and the decisions made in the first few months of a project can lock […]
