If they ever did get a solar roadway panel work correctly,  how far could the power practically be transmitted?

That depends on how much secondary electronics you attach to it.

Now they can claim there have been able to increase the efficiency of the installation (as power produced vs consumed)  :-DD

Looks like our mate Scott is taking out the stuff from the panel box, and the hole has been filled with sand.
Doesn't make sense if they are just replacing the panels.

Public safety.  Filling with sand decreases the trip risk, but sand can be removed very easily.  Wait for the area to be paved or concreted for a full surrender.

 :-DD LOL!
I find it strange though that there is nothing about 'upgrading' the installation on their website. Wouldn't that be worthy of a press release?

A couple of articles regarding the construction work.

Three years later, Solar Roadways is updating the demo with its SR4 model, which is designed to produce 50 watts, compared to the previous 36 watts.

Has anybody written to "jstapleton@sandpointidaho.gov" to point out that the previous ones didn't produce any Watts at all?

No longer "Coming soon"?

Anyway, do we have some numbers on how much power those solar panels consumed since they were installed? Those heaters they were running last winter must have gobbled up quite a bit.

Clearly the tiles have been stolen by the Big Coal, or Big Nuclear, or Big Tarmac or something!
Believe it or not, pointy haired people do exist!

Its back with new more efficient tiles with only half the number of sides.  :)

That's still just a hole. I'm guessing the pattern is for installation purposes (is that where the thick cables go for all the power these things are going to produce?)

Wouldn't a triangle (compared to hexagon) be a worse shape to be covered with square solar panels?
There are also more individual panels for the same area - more connections to go bad.

It's almost as if you believe the people paying for this can do basic math.  :-//

More connections yes but what you can't do with square panels is cover an uneven terrain. In that respect choosing for triangles is a good idea.

Which uneven terrain, this is for Roadways FFS. I'd say such pattern is even dangerous in that its weirdness may through some drivers off (mentally) and cause accidents.

While it's true that triangles can cover uneven surface, if all you have is a bunch of equilateral triangles, you can only cover flat surface. For 3D contours, you need all sorts of different triangles.

In theory but if you look at regular pavement you can often find a tile being cut diagonally to cover some uneven bit of terrain. I assume there is some wiggle room between the panels so the spacing isn't critical. Road surfaces are never perfectly flat and may deform over time for various reasons.

Surly that's just some underlying support.  There is a fair drop from the surface of the concrete to whatever that is creating one hell of a trip hazard.  Certainly the real deal must not be installed yet.

Seems comical that something designed for foot traffic only (in this application) would need an elaborate support under it vs just sand, stone/stone dust or some other common base material.  Paver driveway has far less BS under it.
