The next steps in the development and scaling up of SolaRoad will be (pilot) applications provided in smaller motorways (for example municipal roads) and in specific applications such as bus lines. Whether application onto highways will be possible in the future, cannot be assessed yet. For the potential of SolaRoad, application in highways is not necessary: of the 140,000 km of roads in the Netherlands approximately 90% consists of municipal roads. Highways cover only 5% of the road surface.
