San Francisco: In a big setback for Elon Musk, retail behemoth Walmart has sued Tesla's energy division for providing solar panels that caused multiple fires at its stores, asking the company to immediately remove the panels from more than 240 Walmart locations.

According to a report in USA Today, the Walmart lawsuit, filed in New York State Supreme Court, states that fires broke out at "no fewer than seven" stores between 2012 and 2018 and have "since caused millions of dollars in damage".
