One problem with Solar I hadn't really thought about is how robust they are (not) in storms. The picture at the top of this article shows how a grid on Peurto Rico was destroyed.

https://spectrum.ieee.org/energywise/energy/the-smarter-grid... links to: http://www.theweatherjunkies.com/single-post/2017/09/28/Puer... which shows some that are built more robustly.

Looking around there are lots of panels with hail damage and catching fire etc, its not as simple as I thought!
