As fire departments around the nation weigh in...
More and more will find that residential rooftops are hardly ideal for PV arrays.
For the fireman have to fight a structure that can't really be de-energized while the Sun is out.
I expect someone to come out with foam blocker for just such a purpose.
BTW, silicon does burn -- just like charcoal -- once you get it hot enough. Instead of carbon dioxide -- you get white sand. (Silicon dioxide)
The reaction throws off plenty of heat, too. At least it's not a stinky reaction -- but the rest of the stuff is.

I'm inclined towards PV sourced power. I'm wary of it being installed 'at retail.'
I'm of the opinion that roof falls, fire hazards, and violation of roofer warranties will all cause us to regret ever putting them up.
What seemed so good in the science fiction novels is in reality highly impractical and excessively dangerous.
It's the roof falls. Have you seen the Workmans Comp rates for roofers?
They're in orbit.
Solar oriented ECs are grossly underpricing their risk.
The number one reason that roofers go out of business is roof falls.
At some point, the boys get too casual -- violate safety rules -- and everyone else picks up the pieces.
