German battery maker Sonnen GmbH on Thursday said it would partner with home builder Mandalay Homes to outfit 3,000 new Arizona homes with batteries to store the excess energy generated by their rooftop solar installations.
Mandalay plans to build the homes in Prescott, Arizona with the batteries, which can cost between $10,000 and $20,000. The cost would be part of the home’s sale price and wrapped into the mortgage.
