Engineering

In order to achieve the design requirements of Casa Aguila, the Energy System consists of the following engineering elements.

  • 3 Dual Axis Tracking Systems with a total annual output of over 40,000KWH.
  • A 3.5 KW Wind Turbine capable of harvesting energy during the many hours of the day and night when existing wind resources permit production.
  • A 40 KWH Lithium Ion Battery Bank capable of providing all required power for the property when renewable resources are not meeting load requirements.
  • A cluster of SMA Island Controllers capable of running in grid parallel mode and grid-disconnected mode. The Controller contains software, machine learning and parameters to properly optimize and balance the grid, battery resources, solar and wind. It is capable of load and production shedding.
  • A Power Control System capable of fault detection and subsystem isolation through the use of smart protection relays.

A significant part of the engineering is the programming of the SMA Island Controller and the Power Control System in order to bring true intelligence to the operation of the home and to enhance decision support for both the owner and the power engineer.

In addition to these systems, the Builder and its low-voltage controls contractor will supply to the owner a PowerWise Monitoring System and a whole-house control system from Crestron.

The Contractor and the engineers will work with Solana Energy for the production of construction documents, procurement, permitting and construction.
