Hey remember solar roads and how they were going to revolutionize road construction and usher forth the green revolution? Well you may also remember that France decided to build a 1 km section of solar-powered road as a trial, and the divided internet collectively went "well okay then"

https://www.sciencealert.com/the-world-s-first-solar-road-has-turned-out-to-be-a-disappointing-failure/

quote:

In July, the French daily newspaper Le Monde reported that the 0.6-mile (1 kilometre) solar road was a fiasco.

In December 2016, when the trial road was unveiled, the French Ministry of the Environment called it "unprecedented". French officials said the road, made of photovoltaic panels, would generate electricity to power streetlights in Tourouvre, a local town.

But less than three years later, a report published by Global Construction Review says France's road dream may be over. Cracks have appeared, and in 2018, part of the road had to be demolished due to damage from wear and tear.

Even at its peak, the road was only producing half of the expected energy, because engineers didn't take into consideration rotting leaves falling on the road.

It was all smiles and high hopes in 2016, when the world's first solar panel road, called Wattway, opened. France spent US$5.2 million on 0.6 miles (1 kilometre) of road, and 30,000 square feet (3,000 square metres) of solar panels. It was hailed as the longest solar road in the world.

Media gathered around to take a walk down what was thought to be the road of the future. The French minister for energy said she wanted to have solar panels on one mile of road every 621 miles in the country within the next five years.

Despite grey skies on the day of the inauguration, France was leading the world for solar transportation.

But the brake was never removed, and the wheels never started rolling - so to speak.

It was a bold move beginning a solar panel trial in Normandy, France, since the region doesn't have the most sunshine. Caen, a city in Normandy, only has 44 days of strong sunshine in a year. Thunderstorms also reportedly broke solar panels on the road.

The trial road was meant to produce about 150,000 kWh a year, which is enough power to provide light for up to 5,000 people, every day. Instead, it was making just under 80,000 in 2018, and fewer than 40,000 by July 2019.

Colas, the company that built the road, said in 2016 that the solar panels were covered with resin containing sheets of silicon to make them capable of withstanding all traffic. But since the opening, panels have come loose or broken into little pieces.

In May 2018, 300 feet (90 metres) of the road had to be demolished since it wasn't salvageable.

The engineers also didn't take into account the effects of leaves, which caused damage and limited the amount of electricity the panels could produce.

They also didn't think about the pressure and weight from tractors, two locals told Le Monde.

And now the trial looks like it's all over. Wattway's managing director Etienne Gaudin told Le Monde that it would not be going to market.
"Our system is not mature on long distance traffic," he said. The company would focus on creating electricity for smaller things, like CCTV cameras and lighting bus shelters.

Geeze, who could have predicted that leaves might land on the road? Talk about your acts of god

Yet another example of people trying their damnedest to usher in a 'green technological revolution' so we can keep our society based upon conspicuous consumption going without completely killing the planet.

Lol no we aren't going to tech bro bullshit our way out of this mess. We're just going to have to buy less poo poo and park our cars. No getting out of it.

Solar roads. Whoever the gently caress believed that nonsense probably still thinks Elon is going to show up to dig them a tunnel.

IRC this started with two idiots who groverhoused a lovely walkable solar panel and then hired a PR company to do a Kickstarter making insane promises of what you can do with that. None of them were engineers or had any idea what they were doing so they got a shitton of money from backers.

Then some french city doubled down with 50mio on this idiocy for some reason, probably cancelling imporyant repairs on some school or bridge or something

They have trialed this in the Netherlands. Spoiler: It broke and was half as efficient as roof mounted panels (and way more expensive).

There's a whole bunch of these solar loving roadways, there's this one in France of course, a bike path in the Netherlands and even Germany had of course the most retarded one with LEDs and heaters built-in in highway rest area or something.

Remove the trees so no leaves fall and obstruct the solar panels.

maybe instead of putting the solar panels in a place where they will be crushed all day long by different poo poo they should just build some dedicated solar plants.

I've worked in the solar industry for the past 12+ years. System design, sales, tech support. Also a background in EE.
I also live outside of the town where the first solar roadway company was started. They got a kickstarter and then a 2 million dollar federal grant.

It is the most goddamn stupid idea I've ever seen.

Here's a lesson for those that are new to solar. Solar panels have to be in the sun!

Dirt, leaves, oil, constant shadows from vehicles, will all dramatically decrease production.

Then you get into transmission lines. In a town with existing infrastructure, sure, not too hard to tap into the grid. But these people advocate "putting them out in the desert where there is more sun and fewer cars!" So, you going to build an entire electrical transmission grid to go with that?

Maybe a mechanical engineer goon can chime in, but I'm pretty sure building roads out of tiled pieces is not mechanically sound for long term stability for heavy and high speed traffic. Works great for chariots and wagons, but unstable to support modern traffic. They shake loose over time.

There is a demo display that was installed in the downtown park. The panel-tiles had to be replaced twice so far. The originals cracked and leaked water because they didn't fully seal them, and the current mess looks like pure garbage. Discolored panels (due to lovely manufacturing), gaps, looseness in the tiles, etc. And this is a walkway area, they aren't even in the street. It's embarrassing to even be asked your opinion on it.

Here's a thought, lets put panels on roofs, carports, pole mounts first, you know, where they will actually get sunlight on them.

It’s usually a million a mile for basic new road construction, if it was actually producing power the project probably wasn’t as disastrous as they’re making it out to be. Roads are expensive in general, and a financial sinkhole since there’s significant & continuous maintenance costs.
