What happened
A solar panel on the roof of a large industrial building in south Louisville caught fire on a Wednesday afternoon in September 2026. The fire was reported just before 3 p.m. in the 8700 block of Minor Lane, near Okolona. The building is Grainger Industrial Supply and is nearly 1.5 million square feet. Video showed one of 12 chunks of the solar panels scorched. Firefighters brought the fire under control after about two hours. No employee injuries were reported. Four firefighters went down due to heat exhaustion.
Contributing factors
The cause of the panel fire was not reported. Responders described strong sun on the roof and heavy protective gear, including a respirator, as making the work harder. Four firefighters went down due to heat exhaustion.
Lessons learned
- A fire in a rooftop solar array on a very large building can keep crews on an exposed roof for a long time.
- Heat-stress planning matters when firefighters must work in sun, heavy gear and respirators.
- The cause was not reported, so operators should still be ready to isolate rooftop arrays and give fire services clear access and site information.
