The world’s first solar road was opened in the small French village of Tourouvre-au-Perche in Normandy. The one-kilometre long solar road is made with 30,000 square feet of solar panels. These panels have been covered in a silicon-based resin that allows them to withstand the weight of passing vehicles. It can generate enough energy to power street lighting in the village. Â It took five years and cost $5.2 million to develop it. It will be used for a two-year test period to check its standard output.
