Does this also include the energy needed in recycling it. I hear it's nasty stuff. Not really bio-degradable.

That's my understanding and fits with my own experience. The second hand panels that we put on our house 14 years ago are still going strong. They do become a bit less efficient over time, but they still produce quite a lot of power with no maintenance. Don't know about recycling them as I've always understood that they will stay on the roof and keep supplying us with power.
