Solar Panel Highway Experiment Crashes

Solar highway

The French media wrote about the fiasco, which befell the experimental road, opened three years ago in Turuvre. At that time, the project seemed very promising: 1 km of the public highway were laid out with solar panels with shockproof coating. They were supposed to generate about 150,000 kWh of energy per year and provide it with road infrastructure.

The first problem of the project was a mistake with the location – to show that the energy of the Sun can be used everywhere, the road was laid in the north of the country, in Normandy. But there are only 44 sunny days a year, plus a lot of deciduous trees, and the engineers did not take into account that the foliage that fell on the road blocks the access of sunlight to the panels. As a result, by 2018, the highway generated less than 80,000 kWh of energy, and by June 2019 this figure dropped to 40,000 kWh.

The second mistake was that the developers did not take into account the heavy tractors used by local residents. As a result, the panels became loose and began to crumble, after two years already 10% of the road had to be changed due to the inexpediency of the repair. Ordinary trucks did damage, and such a highway turned out to be very vulnerable to lightning strikes and rainfall. Protect panels on an area of ​​3000 sq. m was difficult and, more importantly, expensive, so no action was taken.

As of today, they state in the panel manufacturer, there is no practical sense in this road. But it cannot be said that $ 5.2 million was wasted – the failure of the experiment clearly showed that such projects were not practical. And instead of roads, solar panels must be installed where they will be less vulnerable to various threats.
