Solaroad HQ (TGW) – Solaroad Group, LLC has come up with an innovative way to ensure that its solar panels are facing the sun: cylindrical solar panels.
Their cylindrical solar panels, the ElectraWall PV System, can be attached to almost any surface: walls, light polls, rooftops, etc.
However, Electrawall does come with one serious deficiency: never will all of the solar panels be utilized.
Information on efficiency was not available.
