Solar route in France

The first solar road test has now been in operation since 2016. Does it keep its promises? In reality, electricity production is much lower than expected: 409kW/h per day instead of 770 kW/h per day, means 47% less. This makes electricity per kW/h less profitable, and may compromise future investments. In comparison, the solar park in Cestas near Bordeaux produces electricity at a cost 10 times lower.
