Featured Project
Utah Self-Sustained Compound
Large Off-Grid Residence
Mayfield Renewables’ involvement began with a feasibility study and expanded to include engineering, permitting, and construction support. Designed using EPC inverters and Ageto controls to provide 100% resiliency with minimal grid support, this large, single-phase system presented multiple, diverse engineering challenges to overcome. Mayfield worked closely with the EPC, Creative Energies to develop solutions that were both technically sound and cost effective to accomplish the client goals.
Project Highlights
| Location | Heber City, Utah |
| Size | 705 kW DC PV with 1,152 kWh DC energy storage |
| Completed | In process: Fall 2023 |
| Equipment | Heliene modules EPC inverters Alencon Spot 1000 optimizers Blue Planet Ion LX-HV ESS Ageto controls |
Featured Project
Village of Galena
Community Microgrid
The Tanana Chiefs Conference contacted Mayfield Renewables to plan and engineer a community microgrid to eliminate the village of Galena’s reliance on diesel fuel. This community project is made possible through GRID Alternatives’ Tribal Solar Accelerator Fund. The system will satisfy all of the Village’s annual power needs, resulting in substantial financial savings. Mayfield Renewables is responsible for the full electrical engineering of this PV and energy storage system as well as the medium voltage interconnection with the existing electrical system. This system is currently designed with EPC inverters and Ageto controls.
Project Highlights
| Location | Village of Galena, Alaska |
| Size | 1.2 MW DC PV with 1 MW AC energy storage |
| Completed | In process |
| Equipment | EPC inverters Ageto controls |
“Mayfield Renewables is an outside design firm but, for all intents and purposes, we think of them as an extension of Borrego staff. They know our standards, they embody our same principles, and we trust them wholeheartedly to deliver the quality that our customers have come to expect from Borrego engineering.”
