These extra steps are pretty important—the flat surface required for transit isn’t exactly ideal for capturing sunlight for power generation. In bike path form the cells are 30 percent less efficient than they would be placed within a standard solar installation. As a result, when this first test strip is extended to its full 100 meters (328 feet) in 2016, it will provide about enough electricity to power three households.
But it does make practical use of an untapped surface area, and there’s plenty of roads available for transformation. Indeed, TNO is not limiting their ambitions to bike paths; the institute estimates that up to 20 percent of the Netherlands’ 140,000km of road could potentially be adapted into SolaRoads, which would amount to an additional 400 to 500 km sq (154 to 193 mi sq) of energy-generating PV which could be fed into the grid, or used to power signage and traffic lights.
