Welcome to the board Jim....Solar heating is really terrifficc....sometimes, like I've taken a hair dryer to melt some ice off an old lawnmower that I wanted to work on about half-hour or so then along comes the sun and melts the rest in about 10 minutes!
You can run across free glass ever so often so many oppurtunities.
Have Fun!
