Wait, they are doing some fantastic things with nano tech and solar
panels
at the moment.

As you know standard panels return about 11% efficiency, with the nanotech,
the panels can be painted onto a surface but they only return about 3% at

But are they even green? IIRC, the manufacture of photovoltaic panels=20
uses more energy than they would be likely to generate over their=20
expected lifetime.

Not forgeting all the work required to generate =A31000 to spend on them!
