Solar Roadways and Solar Highways are being developed to Harvest Solar Power on roads and near/around the roads. Solar Roadways and Solar Highways generate electric power that can be used for charging electric vehicles (EV), other transport vehicles, powering on-road/roadside electric appliances, and also powering homes and industries. Already Piezoelectric Roadways/Highways are in development to harvest vibration energy while vehicles passing. Some energy companies are trying to combine both the Piezoelectric and Solar Energy Harvesting technologies to generate more power from Highways and Transportation.

Solar Roadways & Solar Highways Harvest Solar PowerOne of the great things about solar photovoltaics is that all they need is an open-to-sky place on ground, and some basic maintenance, and they pump out electricity all day long. But finding a piece of ground that can be devoted solely to solar collectors can be a challenge, especially in the populated areas that need the power the most, so you will often find solar panels perched atop some structure, where they are exposed to higher winds, and are more difficult to maintain. But researchers found the solution to this problem in the unused spaces that surround our national grid of highways.

Solar Roadways Inc. developing solar road panels that can be mounted on roads to harvest solar power. When multiple Solar Road Panels are interconnected, the intelligent Solar Roadway is formed. These panels replace current driveways, parking lots, and all road systems, be they interstate highways, state routes, downtown streets, residential streets, or even plain dirt or gravel country roads. Panels can also be used in amusement parks, raceways, bike paths, parking garage rooftops, remote military locations, etc. Any home or business connected to the Solar Roadway (via a Solar Road Panel driveway or parking lot) receives the power and data signals that the Solar Roadway provides. The Solar Roadway becomes an intelligent, self-healing, decentralized (secure) power grid.

Solar Roadways & Solar Highways Harvest Solar PowerThe Solar Roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels that collect energy to be used by our homes and businesses. The ultimate goal is to be able to store excess energy in or alongside the Solar Roadways. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity. This, in turn, cuts greenhouse gases literally in half. Each individual panel consists of three basic layers:

  • Road Surface Layer – Translucent and high-strength, it is rough enough to provide great traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. It is capable of handling today’s heaviest loads under the worst of conditions. Weatherproof, it protects the electronics layer beneath it.
  • Electronics Layer Contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element. No more snow/ice removal and no more school/business closings due to inclement weather. The on-board microprocessor controls lighting, communications, monitoring, etc. With a communications device every 12 feet, the Solar Roadway is an intelligent highway system.
  • Base Plate Layer – While the electronics layer collects energy from the sun, it is the base plate layer that distributes power (collected from the electronics layer) and data signals (phone, TV, internet, etc.) “downline” to all homes and businesses connected to the Solar Roadway. Weatherproof, it protects the electronics layer above it.
