Criticism[edit]

In 2014, Jonathan Levine, a professor of urban planning at the University of Michigan, expressed doubt regarding the political feasibility of the project on a national scale. He suggested, however, that a single town might be able to deploy the concept in a limited test case such as a parking lot.[17]

Journalist David Biello, writing in Scientific American, noted the difficulties of the project in dealing with material limitations, particularly in its choice of making the surface of the panels from glass, which "must be tempered, self-cleaning, and capable of transmitting light to the PV below under trying conditions, among other characteristics—a type of glass that does not yet exist."[18]

Sebastian Anthony noted in ExtremeTech that the cost to replace all roads in the United States with Solar Roadways panels would come to approximately $56 trillion, based on Scott Brusaw's cost estimate of $10,000 for a 12-by-12-foot (3.7 m × 3.7 m) section.[19] The USDOT announcement of Phase IIB funding in December 2015 mentioned that because the solar cells were still manufactured by hand, they were "very costly to produce".[3]
