The venture is a product of Mercedes-Benz Energy, a new subsidiary created in 2016 to move into the residential energy storage market. The company builds 2.5kWh lithium-ion batteries in Germany, which can be interconnected to create a system as large as 20kWh.
David Bywater, CEO of Vivint Solar, said in a statement that the price of the system would vary. “A fully installed 2.5kWh battery system, when paired with a solar energy system will cost about $5,000,” he said. But a 20kWh system will only cost about $13,000 fully installed. “Some installations may cost more or less depending on customer needs/special requests."
