France plans to install 1,000 kilometers of solar panel roadways in the next five years, Global Construction Review
reports. That’s an ambitious goal, but not at all out of reach, because
the technology is ready to go: the 7-millimeter-thick photovoltaic
panel called Wattway,
produced by French transportation infrastructure firm Colas. These
panels can glue onto existing road surfaces to draw power from the sun,
while providing enough grip for cars and trucks to drive over them.
Colas says one kilometer is enough to power public lighting for a city
of 5,000 people and 20 square meters of Wattway can power a single
French home.
