Tom, don't they have shingle-type cells for home use already? I thought I saw or read something on them but maybe it was more along the lines of something that will be available in the near future.
I couldn't get away with them since they wouldn't pass Historic District Commission muster anyway, but they'd be a good option for those not wanting a bank of panels attached to their roofs.
If I had to pedal to use my computer I'd be in a helluva lot better shape!
