Photovoltaic road tested in China
Context
China successfully tested its first photovoltaic highway based on home-grown technology in the country’s eastern Shandong province on Thursday, according to reports from Xinhua. The road has wireless charging systems for electric vehicles
Road constructed using solar panels
The road is constructed using solar panels which have a thin sheet of clear concrete on top of them, protecting the surface
- The panels were built to transfer energy to electric vehicles passing on top of them
- The one-kilometre segment of solar-powered highway covers a surface area of 5,875 sq.m
- The stretch has three layers. At the bottom is an insulator to prevent moisture from getting to the photovoltaic devices in the middle layer, and on top is the layer of transparent concrete
- The tested segment of highway can generate 817.2 KW of power and is expected to generate 1 million KW hours of electricity each year. The electricity generated will be connected to China’s national power grid
China becomes 2nd country
China has become the second country to construct a photovoltaic highway. France introduced the world’s first photovoltaic road fitted with solar panels in late 2016.
