The massive warehouse fire that has been burning for more than six days and causing health hazards for much of Los Angeles is believed to have been started during servicing of the solar photovoltaic farm on the facility’s roof, which sells power to the city’s grid.

“We believe the fire started on the roof when the owner of the solar array, Altus Power, was doing tests,” warehouse operator Lineage Logistics said in a June 23 update.
