Arizona home builder Mandalay Homes is partnering with German battery maker sonnen on a high-efficiency planned community in Prescott, Arizona. Sonnen will deploy over 10 GW of PV and 11.6 MW of battery storage systems on the 2900 new homes.
The smart "eco-homes" will be capable of communicating with each other to form a hive of systems, branded as a sonnenCommunity. The hive acts as an intelligent network of clean energy storage systems that collaborate to form a VirtualPowerPlant (VPP), with the capability to dynamically interact with the precise needs of the electricity grid on a day-by-day basis to increase grid efficiency and lower operating costs.
The sonnen energy storage system stores excess solar energy generated during the daytime in a smart battery. Later, when the sun is no longer shining, the storage system is calibrated to discharge and meet the specific load of the home. This process is known as solar time shifting, and enables customers to utilize the abundant solar energy to power the home during both day and night.
"This master planned Jasper community represents the single most significant innovation in how new homes can contribute to the decarbonization of our electricity grid. The 2,900 homes in which the sonnenCommunity will be deployed in Prescott Valley represent a true clean energy revolution, setting a new standard in energy efficient communities that will challenge the status-quo associated with the US electricity grid," said Blake Richetta, sonnen's Senior Vice President and head of the US Subsidiary.
The Jasper sonnenCommunity will represent the first Demand Response and Grid Services Ready aggregated network of residential energy storage systems, deployed as a standard throughout a master planned new construction community in the US. Select sonnen systems deployed by Mandalay will also be able to execute demand control commands utilizing smart home devices.
"Mandalay's vision is energy savings without sacrifice," said Geoff Ferrell, Chief Technology Officer at Mandalay Homes. "Therefore, it is imperative to deploy simple load shedding techniques, in a logical and routine fashion, without disrupting everyday comfort and behavior. Our energy modeling with sonnen proves that this is possible with existing technology, and therefore is within reach for virtually any US home builder."
