The Otis also doubles as a weapon when other mad scientists annoy you.
It can be used as a club....or inserted!!!
Back to weather thread topic.....
I've been told my neighbour shelled out £10000 for his solar panel installation and expects a 8-10 year payback...though it adds saleable value to his home as well.
Unless I am missing something on the 'feed in tariff' scheme, my £800 pa electric bill would take longer to payback!
You can normally sell the excess back to the grid, and on occasion you may need more than it will produce so it's complex, but if you're neighbour spent 10K a month ago, it'll be less now. They have hit the stage in production volume like computer memory did where the output is getting better and better and the price is plummeting. Cost of camera memory cards would be a good parallel.
