Tesla entered the solar business in late 2016 when it acquired SolarCity for $2.6 billion. Among other things, Tesla Energy (formerly SolarCity) installs rooftop photovoltaics, ground-based and carport solar energy systems. While Tesla does not break out revenue from solar on its own, "energy generation and storage" represented only 6% the company's total revenue in 2020, but grew by 30% from last year, according to its 2020 end-of-year financial filing. On a January 27 earnings call, Musk told analysts: "We're putting a lot of attention on solar and it is growing rapidly. So I think it will not be long before Tesla is by far the market leader in solar." Tesla's systems have been installed at homes including military housing units at Fort Bliss and other bases, schools in the L.A. unified school district, and commercial facilities including Walmart stores and Amazon warehouses.
