The image of benches shading the panels really says all you need to know.

[–] troyunrau@lemmy.ca 3 points 7 hours ago

This depends on what you're optimizing for. If you are optimizing for total energy captured per square metre, then you're right about the benches.

But suppose you have a sufficient flux even with some areas being covered so you aren't bothered by the shadows. Wouldn't it be aesthetically superior to have uniform tile types? Or would you prefer they micromanage the tile placement such that the tiles below the bench shadows are different?

Anyway, I think it is a good idea. Better than the silly solar roadways crap.

[–] kameecoding@lemmy.world 5 points 8 hours ago

Literally just put them 2 and a half meters higher so they provide shade for sitting in the bench instead of people shading the panels.

[–] bruhduh@lemmy.world 4 points 9 hours ago

True, they should use benches like these for solar rays to pass through

[–] Bezier@suppo.fi 28 points 11 hours ago

Solar freakin roadways

Not freakin again.

Solar Roadways 2.0?

Y'all missing the whole point here.

If an area requires covering, it might as well produce some power. And cells on the ground aren't as bad as they're made out.

I have one laying flat in the yard powering a 12V water pump. Been there for 6-months, covered in pollen and dust, weeds growing over one side, grass cuttings on top, never cleaned, works fine. I have another on my shed roof at our camp. Same deal with the pollen and dust, works fine. But guess which one is easier to clean?

Cells don't have to be pristine to produce power. And if you do want to clean them? The installation pictured looks easy to work with a garden hose and squeegee, couldn't take 30 minutes. Use concrete instead? OK, now you have to power wash it. What a pain.

The cells ability to produce power is directly related to how much light it gets. You'd be able to measure it. Take a reading as is. Then remove the weeds, take a reading. Then clean it, take a reading. Then point it at the sun so it's as perpendicular as you can get it, take a reading. Each time you should see an increase in output.

Panels on the ground that people are going to walk in (or drive) are going to be prone to damage. I'm fact, they've already done ground solar panel installations and they've all failed as far as I know. When placed above, you don't need to over engineer it to survive things. Concrete, can handle a lot more wear and tear, as well as being easy to repair and recycles really well.

Basically, there's an objectively better way to use the panels.

For fuck sake!

Put solar on roofs, not where people walk/drive!

Can we please stop wasting resources on this shit?

[–] phoenixz@lemmy.ca 11 points 12 hours ago

Oohh, solar roadways, part 4621559

Trailer: they suck, don't work, and are made by people who have no idea what the fuck they're doing

[–] OmegaLemmy@discuss.online 39 points 15 hours ago (2 children)

Can't they just make it a roof?

[–] thisfro@slrpnk.net 24 points 15 hours ago

Yeah feels already hot from just looking at it

[–] Agent641@lemmy.world 7 points 15 hours ago

And put some goddamn plants under it.

[–] stinky@redlemmy.com 3 points 9 hours ago

does anyone know where I can get strong opinions about solar rods?

[–] ExcessShiv@lemmy.dbzer0.com 21 points 15 hours ago

We need more trees and green areas in cities to shade and cool them down, not more heat soaking open areas that heat them up!

When are they going to learn that solar roads are never going to be practical?

[–] TheTechnician27@lemmy.world 19 points 14 hours ago* (last edited 14 hours ago)

PV Magazine is more or less an outlet for press releases by companies trying to innovate (often in air quotes) with photovoltaics. I'm honestly not even sure why it's allowed here; it's completely uncritical. May as well cite a press release on the manufacturer's website at that point instead of laundering it through a magazine.

[–] BETYU@moist.catsweat.com 6 points 14 hours ago

never use solar panels for side walks its a stupid idea. and there is a reason why solar panels are placed at angle and not flat on the ground.

[–] Peer@discuss.tchncs.de 5 points 15 hours ago

Hope the predicted capability is realistic. As previously we’ve seen comparable projects be less so: https://www.dutchnews.nl/2023/07/solar-bike-path-fails-to-meet-electricity-targets-again/
