Polaris photovoltaic solar photovoltaic France road also failed

Editor's note: TuLu in northwestern France, er the pell town into use solar road 2016, proved a failure, however, neither energy nor the economy. Now this road has been damaged beyond maintenance, parts have been broken down.

it is well known that belongs to the non-renewable energy sources such as coal, oil, natural gas, use up a bit, a little less. But with the development of economy and population has increased dramatically, the non-renewable energy consumption more and more, one day we will face the crisis.

as a result, most countries in the world have stepped up efforts to develop renewable energy. Among them, the solar energy has become an important part of the energy we use, and develop continuously.

in order to make full use of solar energy, human did a lot of experiments, however, many tests have ended in failure.

in 2016, the world's first solar road in northwest France TuLu husband, the pell town officially put into use. Three years later, the world's first solar road eventually proved to be a failure, because it is neither economic nor energy saving.

three years ago, France built at a cost of $5. 2 million this is about a mile long solar road and 3 square feet ( An area of 2787 square meters) The solar panels.

today, solar panels, the road there are already cracks and damage, unable to maintain, even part of the road have been knocked down. Road did not achieve the goal of prediction, solar portal, because the engineer does not take into account in the way of rotting leaves, also did not consider the pressure and weight of the tractor.

as for the goal of the test road is produced each year about 150000 kilowatt-hours of electricity, it is enough to provide illumination for as many as 5000 people a day. Actually how? Learned, solar panels, from 2018 to now 21 months of generating capacity, the amount is less than 120000 KWH, China solar energy network, solar power network, and the total revenue in three years on the sale of electricity, distance estimated revenue targets also amounted to less than a year.

similarly, France built the solar road, also built in China, still the world's first photovoltaic (pv) highway. But both are the same fate, failure.

the total length of 1. 12 km photovoltaic highway opened at the end of 2017, covers an area of 5875 square meters, is expected to produce about 1 million KWH. Results, since the opening, the photovoltaic cell components are frequently damaged, have to regular maintenance, closed. Crush and damage reason mainly is a heavy duty truck, followed by erosion of rainwater, the surface of the battery pollution cleaning is also a big problem. Shandong commercial daily reporter this year to visit the photovoltaic (pv) highway, driveway photovoltaic panel only ten metres.

at present, the use of solar energy is not very popular, the use of solar power still exists the problem of low cost, high conversion efficiency, the failure of the solar road is also a setback of human in the way of using solar, believe in the future we will have a better way to utilize solar energy.
