In actual roof fires with roof mounted solar panels fire damage has involved areas of between 1 000 and 183 000 ft 2 93 and 17 000 m 2.
In the most extreme case the fire spread to the inside and destroyed the entire building see fig.
Although extremely rare fires can originate from solar panels.
Identify the system if possible.

Assume every electrical circuit is live even if you.
As mentioned fire and electrical codes are also being updated to deal with these issues.
