According to scientists, about 0.5% of the total surface of our planet is covered with roads. This fairly large area is used only for movement of cars, but why people do not use it for other purposes? For example, roads can be covered with solar panels that produce electricity to power the streetlights. It is a thought a few years ago came up with the representatives of the French company Colas. In 2016 the world’s first road of solar panels was finally built, but now it doesn’t. The fact that the company has made many stupid mistakes.
Solar road Wattway a length of 1.6 km was built in the French region of Normandy. About 3,000 square meters of this path was covered with solar panels that, according to calculations of the creators, could supply energy to lamp posts in Turov-AU-Perche. The road construction has been spent about $ 5.2 million, but to recoup the amount spent, the company ultimately failed.
The longest road of solar panels
First, the road was well-liked, even the French Minister of energy. He liked this idea so much so that he announced that he wanted to see solar panels on every 1000 kilometers of all roads of France. But, it turned out that the road of solar panels generates so much energy than expected. The creators wanted to develop 150 000 kWh of electricity per year, but by July 2019, they noticed that the road generates 40,000 kWh battery performance has steadily declined and the reason for this was, roughly speaking, the stupidity of the creators.
Why blew the road out of solar panels?
The company made a big mistake at the beginning of the construction of the road. It was built on the territory of Caen, which is one of the most cloudy in France. According to scientists, the average people of this town see the sun, only 44 days a year. So what kind of solar energy can be discussed, if most of the time the sky is covered in a dense layer of clouds?
Also, when the construction of the road in 2016, the company Colas covered the surface with resin. In her opinion, this coverage was intended to protect the batteries from cracking during driving. Perhaps the resin really withstand the pressure of the wheels of the cars, but the company did not think that this route can drive trucks. In the end, most of the solar panels was cracked, so I had to disassemble 90 meters of the road.
In addition to this, the company has forgotten about the fact that over time the road may be covered with debris and leaves. Only after some time they realized that dirt-covered solar panels are almost useless. How much energy could create a dirty and cracked panel is unknown, but it is hardly enough to power even a pair of three lights. Then why do we need such a road?
