Solar Roadways is a project to develop and build energy-efficient road surface materials that make use of solar energy. Instead of asphalt, toughened PV panels are used, which include embedded lighting that can act as road markings and driver alerts,
Each panel is equipped with PV cells, circuit boards, 128 programmable LEDs and a heating element to get rid of ice and snow. They are topped with 'super-strength' textured glass, which has proven to be highly sturdy and impact-resistant.
The first prototype parking lot is comparable to a 3,600 Watt solar array, although the amount of power collected depends on the amount of sunlight exposure. Power and data cables are neatly organized in a 'cable corridor' alongside the parking lot, providing easy access to power companies performing maintenance or looking for data.
