You might want to update your assumptions.  Solar around here is already down to 7 cents per KWH.

Wow, that is a bummer.  Can't survive that.  But the home solar panels now are all guaranteed to withstand up-to golf-ball sized hail.  They are something like 3/16ths tempered glass.

So if the hail did not break skylights, then solar panels might have survived.
