Nantes worked during February and the beginning of March 2020 on the implementation of a solar power plant, made with organic, flexible and semi-transparent photovoltaic films. The power plant was installed at the local Cité des Congrès and is expected to produce 410 kWh per year. The energy produced by the films will be stored in a 1200 Wh capacity battery to then be used to supply an information and mobile phone charging station. Learn more in this video.
