The name of those solar panels is PowerFLEX. Copper Indium Gallium DiSelenide (CIGS) solar cells
Those flexible solar panels (CIGS) are suitable for use on flat roofs. As you can see on the image bellow, the lightweight and flexible panels are easy to roll on the roof. The installation costs are reduced to minimum.
PowerFLEX is made from thin-film photovoltaic Copper Indium Gallium DiSelenide (CIGS) solar cells. This CIGS solar material is the key to producing highly efficient solar panels that are lightweight and flexible. It is this quality that allows the material to be installed with significantly less hassle than standard polycrystalline silicon panels that require racks. The PowerFLEX material can be quickly and easily rolled onto any flat roof, covering it entirely if required without needed the additional space racks can take up. The lightness also helps to allow them to be installed without the same compilations that can occur with the polycrystalline silicon panels.
Due to its highly efficient nature, and low cost of materials, CIGS has been called the wonder child, or market darling, of thin film photovoltaic (TFPV) materials business. Industry analyst firm NanoMarkets projects the CIGS PV market will grow from $403.1 million in 2011 to $2.6 billion in 2016.

Global Solar is the only manufacturer in full-scale production of CIGS (Copper Indium Gallium diSelenide) PV cells on a flexible substrate. The Company is dedicated to constantly improving the efficiency of its solar cells and overall manufacturing process. Global Solar achieved 10% average solar cell efficiency—the first CIGS company to reach this milestone in a production environment.
