Solyndra solar collector
This is a solar collector from Solyndra, one of the many solar companies started in the U.S. to take advantage of relatively cheap thin-film solar cells. The solar cells (in black) are wrapped around glass tubes and can collect light from the top and, when reflected off the white membrane, from the bottom. Installation of the solar collectors, which are designed for flat roofs, is quick since the collectors are self ballasting and don't need to be screwed into rooftops.
