According to France’s minister of ecology and energy, Ségolène Royal, the tender for this project is already issued under the “Positive Energy” initiative and the test for the solar panels will begin by this spring.The photo voltaic solar panels called “Wattway” which will be used in the project is jointly developed by the French infrastructure firm “Colas” and the National Institute for Solar Energy. The specialty of “Wattway” is that its very sturdy and can let heavy trucks pass through it, also offering a good grip to avoid an accident. Interestingly, this project will not remove road surfaces but instead, the solar panels will be glued to the existing pavement.
