The modules, consisting of solar panels 19 feet long and 1.5 feet wide, are actually made with CIGS (copper, indium, gallium, selenium) cells that work as well as their rigid counterparts.

Thin film solar cells are yet another competitor to classic ones, and attract customers through the fact that they're thin, flexible and cheap. And they're also pretty inefficient (20% at most).

To reduce even more the costs, these solar cells are build with an inexpensive ink-based process.
