US supermarket chain Walmart is suing Tesla’s energy division, after solar panels on seven of its stores caught fire.
It alleges that the firm was negligent in how it installed the panels on the roofs of the stores.
Court documents describe a string of fires that occurred between 2012 and 2018 at Walmart locations in Ohio, Maryland and California.
Tesla has not yet responded to the claims.
The lawsuit alleges that the first fire occurred at a Walmart store in Long Beach, California in 2012.
Another in Beavercreek, Ohio, in March 2018 saw customers evacuated and the store closed for eight days.
Walmart is asking Tesla to remove solar panels from all its stores and to pay damages.
It alleged that Tesla deployed individuals to inspect the solar systems who “lacked basic solar training and knowledge”.
