One undeniable thing about solar panels on a building – they look like solar panels. And often aren’t that attractive. Until now. Solar Ivy is a printed film photovoltaic cell available in a variety of shapes, colors and efficiencies. 
The idea is to array the leaves across a structure in such a way that they look like natural ivy-like growth while producing up to four watts of electricity per leaf. The shapes are small and adaptable enough that they can even be used to render a logo on the side of an office building. So, in a few years your favorite ivy-covered building may be leading the march off the power grid.

Thanks Dave for writing this interesting article.
This kind of new technology would be great with older, listed buildings where it would be hard to get a permit for conventional solar panels. This way new and renewable energy would be available to a lot more people depending on the price though.
Take care,
