Hey the idea is too good. I have always loved to look at the trees outside my window and this green leaf shades will also be perfect for some parts of my home where we get sufficient sunlight, at least in mornings.
Fantastic idea to have windows generating electricity, spl in apartments where having panels in roofs is not feasible.

I too loved this uber-practical concept. Would love to swap these kinda power generating shades with my curtains.
