For individual homes sourcing electric from a wind or solar farm is going to be the way to go over actually having a panels and wind installation at your house, technology that will age out.
Last week I was at a Council Meeting for a town I represent as their Municipal Engineer.
One of the topics for discussion was a fire at 1 1/2 story wood frame house.
Normally a house fire wouldn't be brought up at a council meeting.
But, in the case of this house, the issue was Solar Panels on the roof.
I learned a few things :
1.Squirrels love building nests under Solar Panels.
They are warm in the Winter.
2.Squirrels also like to "burrow" under roof shingles
3.Squirrels like to chew on any wiring.
In the case of this house, they chewed through the wires,
that created shorts, that started the fire.
4.Because of the weight of the panels, they couldn't allow
fire fighters on the roof to "vent" the attic to control the
blaze.
All they could do was put water on it from above.
5.The weight of the panels makes a roof structure likely to
collapse.
This one did, and took most of the house with it.
6.Local fire departments tell home owners, when they put Solar Panels
on roofs, they need to be inspected at least a couple of time a year.
But no one does.
