Grow - Ivy like Solar cells GO GREEN!

Came across this here at OhGizmo.  This is basically a system of Polaroid sized solar panels that can be clipped into a wall and wired up to  harness whatever sun energy it can sap!  Doesn't look to shabby as an Ivy like surface and should be easily placed on many building surfaces.  Wonder how it would handle wind, snow and rain.  Sounds like something for sunny dessert cities!
