The special pavement combines three layers: an isolating bottom, solar panels in the middle and transparent concrete on the top. The solar-powered highway has been built by the Qilu Transportation Develpment Group. Its total capacity accumulates to 800 kW while annual generation of electricity could reach up to 10m kWh.
