The Big Idea

Solar road panels are made with layers of super-strong glass embedded with photovoltaic cells, electrical wiring and LED lights, which can be used to create signs on the surface directing traffic or alerting motorists to hazardous conditions.

When connected between highways, residential streets, parking lots and driveways, the system of solar panels not only creates a vast, power-collecting network; it also creates a system of delivery that would eliminate the need for above-ground wires and dramatically reduce instances of widespread power failures.

According to Scott Brusaw, co-founder of Solar Roadways, a single mile of solar road panels would be enough to power 428 homes. And that’s assuming there are only four hours of sunlight in a day.
