Solar panels on a building at Meridian Winery east of Paso Robles caught fire Wednesday morning, according to Cal Fire.
The panels were on the roof of the building where red wine is fermented.
Firefighters are trying to see if the flames spread to other solar panels, but have to wait for the electricity to be turned off.
Meridian Winery is located at 7000 Highway 46 East. The fire was reported at 10:25 a.m.
