Last year, Tesla dropped the “Motors” from its name, and the reason was diversification. It doesn't just make electric motors anymore, or the cars to put them in. It also makes electric installation equipment, like the Powerwall residential and industrial battery packs, and (through its 2016 acquisition of SolarCity) photovoltaic panels as well. So not only can you drive one of its electric vehicles, but your home, business, and local power grid can be powered by Tesla equipment, too.
