Why not just make solar roofs over things like parking lots and sidewalks? That way it can provide cover and power, you can use off the shelf panels, and they are unlikely to get damaged.

And you can repair them without needing to shut down a whole railway. All these projects to put solar panels in novel places are totally pointless and solving a problem that doesn't exist.
Yeah until we literally run out of roofs, fields, parking lots, and fucking ocean space and are contemplating a fucking Dyson sphere I really don't understand these projects.
parking lots would require the government to own said parking lots. its why you often see them at schools (because its government funded)
I doubt they're doing this and only this.
wouldn't make much sense to put up a solar roof after doing this. it would block the sun.
Covering parking lots is expensive and you lose spots to supports and there's the inevitable car hitting those supports.
Putting panels between rail lines doesn't need a structure so it should be far cheaper and easier to install and fix, even if they aren't ideal.
They will get dirty very fast, either from dirt thrown around by passing trains, or by the brake dust.
It shouldn't be too hard to clean them with something running on the tracks, but it does seem less than ideal.
A chain or wire hanging off a train car and dragging along will "clean" them real quick...
Also the heavy vibration that can occur when a train passes over
In France, solar panels are mandatory for living roofs of commercial and industrial buildings and covered car parks occupying 500 m² or more of ground surface.
At least for right now it's just a test on a 100-meter length of track, but this reeks of a startup trying to innovate its way out of NIMBYs not wanting to put solar panels where they actually belong without considering why nobody has put solar panels in the middle of a railroad track before (cough rocks, dust, wildlife, vibration, and vandalism cough).
PV Magazine is neat for reading about potential new innovations, but one thing I really dislike about it is that it basically just regurgitates what solar companies say about themselves in press releases in a way that's completely uncritical. For instance:
Similarly, removal and installation tests will be carried out to demonstrate that the Sunways pilot installation is perfectly adapted to the constraints related to maintenance work and the operation of the line.
One more reason. The reason they tell people not to lay on the tracks under the train, the freaking cables and chains that could come loose and dangle under the cars and drag along the ground that would cut you in half the long way. Those loose parts would just destroy the solar panels.
Solar panels need to be on every home and how new builds in many countries still don't require them baffles me.
Might be cause they make roof redos or fumigation even more expensive. I had a customer say they were paying 3k to get their panels removed so they could pay another 3k to fumigate the house. Almost doubled the price.
Don't get me wrong, I agree that we should require panels in new builds somehow but I don't know what the best option is.
Sounds like a scam. Houses round me had their roof tiles replaced recently and the guys just took the solar panels off and put them back on after no problem without inflating the price. Perhaps it varies on how the panels are installed, but most I have seen are just under the tiles and attached to the roof frame.
And the benefits far out way the slight extra cost of a roof retile every 20 or so years.
What sort of prices were they charging?
Why did they have to remove the panels in order to fumigate? If the company couldn't work around them then they should have found a different company.
You drop heavy ass tarps on the roof and roll them to tent a house, I'm taking couple hundred pound tarps. The workers need to be able to walk on the roof to set them up, the tarps can and have damaged panels so companies in the area don't fumigate with them on anymore.
I work closely with a fumigation company and that's what they've told us.
Seems like they could use a boom lift and work around them if they wanted to. I'm sure there's a way to cover the panels with plywood to where they wouldn't get damaged. Much cheaper and easier than removing and replacing.
You would need to screw the plywood into the roof so it doesn't shift around and damage stuff during the whole process, nobody is gonna wanna do that. Boom lifts are ocassionally used for extremely tall properties but they add to the price. You're forgetting the biggest issue though, liability. My company stopped doing fumigations cause of the liability involved. Getting the plywood on the roof is gonna take a lot of effort and more than just a boom lift, you're gonna need huge slabs of it to properly cover panels, I don't know if you've seen them but they're not small. They usually cover significant portions of the roof.
At that point it would just be cheaper to pay a company to remove them and reinstall vs all that other effort.
If there was a better way the companies would do it to make money. There just isn't unless the owner is willing to shell out and many aren't, even the rich ones and we work with A LOT of rich people. They own million dollar homes and have multiple homes all over the area.
I don't understand why we are not putting solar panels on every surface possible to be honest.
I'm interested to see how this turns out, because I'm thinking this would significantly increase maintenance costs on those panels due to rocks being kicked up, vibration from the train, etc.
Maybe it’s like a blanket that the train picks up over its head and runs underneath, setting it back down on the ground after it
Reminds me of this, but in reverse:
Pretty close. Quick lets patent it
There shouldn't be any rocks kicked up because the trains should stay on the rails, not touch the ballast.
But dirt, debris, and brake dust will absolutely collect very quickly. Maybe they're counting on rain to keep them clean.
There’s still massive amounts of air pressure changes Those can definitely lift some smaller rocks
You do get the advantage of easy and above all fast placement.
Not sure how this would work out. There's pros and cons I suppose.
Solar FREAKING ~~Road~~Railways!
I was looking for this comment so I can vent my extreme irritation to the world.
God, can this concept please die already‽ If you want to put solar panels where the cars/trains are, just 👏 fucking 👏 put 👏 them 👏 on 👏 top👏
Do not put them on the ground where they will get smushed and covered in dust and snow and dirt. do not. Just make a little roof for the train tracks/road/bike path/sidewalk/game trail/snail raceway and then put the panels on top of the roof and then if you're feeling fancy angle the panels to point towards the sun and if you're feeling really quite fancy then you can use bifacial panels to capture the backscatter from the ground and shit and then we can all be happy. solar ground no, solar roof yes, ground no roof yes. do not play the trolley problem with solar panels on the railroad tracks. we have been doing solar energy for decades and have fucking minmaxed this shit so why are they still trying to do this just STOP.
Fuck.
Person I'm responding to, please know that none of this is directed at you. I'm just sour right now and should get off the internet.
Solar parkings!! Park your car over solar panels!! Solar pools, put them at the bottom of your pool!! Put them INSIDE!
It's like an idiot manically obsessed with solar panels got their hands on some heavy drugs.
anyone remember solar roadways?
This isn't nearly that dumb, because the train isn't actually riding directly on top of the solar cells.
It's close though, random shit gets dragged, kicked, dropped, etc all the time by trains.
A chain , cable, or wire comes loose on a car and goodbye panels and like all of them ...
If a chain, cable, or wire comes loose on a car then the panels are the least of anyone's worries. Also expect emergency brakes to kick in automatically. This is a train, not a bicycle.
I don't why they don't overhang them on frames. It'd cost more upfront, but hell alot cheaper than replacing the broken panels all the time.
Yeah, I looked up the French solar roadways after seeing this to see the headline of 'total disaster'. So as expected.
Good thing they stopped emptying train toilets on the tracks.
This doesn't seem like it would work. Debris falling off the trains, dusty buildup, vibrations, rocks bouncing around the tracks; heck, even just wildlife crossing the tracks. So many things are gonna damage those panels if they're just lying on the ground between tracks, and solar panels are extremely fragile.
I hope they have some sort of bullet proof glass or something over those panels. Probably going to need a special train to spray water over them to clean regularly, too.
I dunno about Swiss trains, but the tracks behind my house in America leave a thick black film on everything, and it's very hard to clean by hand. I think they transport coal.
I feel like the vibration is going to induce microfractures in the photovoltaic crystals, no matter how well the panel is protected from debris.
And the piss and shit.
While I know things are generally more expensive in Switzerland, $685,000 is crazy expensive for just 18 kW (48 panels).
Reminds me of "solar freaking roadways!"

Gut, dass da zwischen den Schienen nie irgendwelche Steine rumfliegen......???
That's not much of a pilot. I run 43kW at my house.
The capacity limit of the system is not the objective of the pilot project.
