Ferri, Carlotta (author), Ziar, H. (author), Nguyen, T.T. (author), van Lint, J.W.C. (author), Zeman, M. (author), Isabella, O. (author)After developing the methodology, we applied it to the case of the Netherlands highways. We show that the average irradiation on the Dutch highway network is around 880 kWh/m2/y, 35% less than the potential of an optimally tilted conventional PV system in the south of the Netherlands. Covering the entire 1600 km of the Dutch highways network...journal article 2022
