The low-key solar panels you'll see above don't scream green, but just because these designs are not ostentatious doesn't mean they are any less effective at providing cheap eco power. From understated panels that you can mount right on your rooftop to tiny ones you can wear around your neck or on a wrist, these solar panels come in all sizes.

There are even furniture designs equipped with low-key solar panels for the ultimate in productive lounging. See these and more above.
