Cosmic’s niche is more planet-friendly: Its founder says its backyard homes can generate enough energy to supply some to the primary house.
But Cosmic says its units' battery and solar energy systems can generate more than it uses, cutting the homeowner's electricity bill.
The studio unit has a five-panel, 2.2-kilowatt photovoltaic system and a five-kilowatt-hour battery.
Its founder told BI that both could be upgraded to become a "power plant" for the primary home.
Even the water systems have been optimized: The ADUs can be further upgraded with a recycling water filtration system, allowing water to be reused for non-drinking purposes like the toilet or washing machine.
