Vivint Solar announced Thursday that it is collaborating with Mercedes-Benz Energy to jointly offer that company's batteries along with Vivint's solar panels.
Vivint, which has installed solar energy systems on 100,000 homes in the United States since its inception in 2011, said the deal is the first time Mercedes-Benz Energy will offer its batteries for residential use with a U.S. solar provider.
The deal also puts Vivint Solar into head-to-head competition with Tesla, the electric-car company that owns SolarCity. Tesla also offers a combination of solar panels and batteries that can power homes.
Mercedes-Benz Energy is a fully owned subsidiary of another carmaker, the German company Daimler AG.
