The Model 3 became Tesla’s best-selling model

 the best-selling electric car of all time, surpassing the Nissan Leaf.

The company also branched out into solar energy products.

A line of batteries to store electric power from solar energy for use in homes and businesses was unveiled in 2015.

 Tesla bought the solar panel company SolarCity in 2016 and offered rooftop solar panels,

a solar roof with energy-generating tiles, and a large battery called the

Powerwall to store the power generated for use when the sun was not shining or as a backup in case of a power outage.

 In 2017 the company changed its name to Tesla, Inc., to reflect that it no longer sold just cars.
