Good news! And since our house is pretty much running north-south, with an unobstructed view of the sun until around, say, mid-afternoon, the aide of our roof facing east should be quite suitable (to get more sun on it, we'd have to remove all the trees, moat of which are 30+ years old, something we don't want to do). One day, there will panels on that roof!

Neat, if you need any mounting tips let me know, I've had a few 'trial-and-error' runs at it.

as things are, that'll take a while (as in years!), but I'll come back to it!
