According to this article, this road consists of solar PV panels covered with a wearing layer of 'transparent concrete'.. I know this has been tried before in other places and the surface gets so scuffed by traffic it becomes opaque, I'd love to know what they are planning on actually using!

As a guess, their strategy might be that the great volume of panels will  compensate for degraded performance?

The fixed flat angle will be a problem along with surface scuffing.

I think the definition they are using for concrete is: A mass formed by coalescence or concretion of particles of matter.
By that definition the matter in the concrete could be anything that forms a solid mass. 
What they are trying to do is address the land issue with solar panels.
Not even half as silly as putting windmills along side the road to capture waste energy from passing traffic.

Only time will tell. What with the concrete wear layer, horizontal installation, and passing traffic, they can't be anywhere near as "efficient" as regular panels (and more expensive). But with new or repaved roads, the cost of conventional paving is avoided, as is the cost of dedicated real estate.

It's all about the money...

Yep, it's all about the money.

What got my attention was the statement that commercial solar was half the price of rooftop solar...

Just a couple remarks.  

1.  If this system, even though inefficient, can replace wind plants, I'm all for it.  Wind plants are super expensive, maintenance intensive, noisy, and a real killer of birds, bats, and insects, Also, no real published info as to what they do to micro and even large scale downwind climates over time.  Bear in mind, the air is 'dead' downwind of operating wind plants, they extract all the energy from the passing air.  Info, if any, is probably close hold or even classified.... 

2.  Can't you just visualize large motorized disk sanding machines with built in vacuums redoing the surfaces of solar roadways instead of crews laying new asphalt as they do atop present day highways?  We need some viable systems using existing roadways, roofs, and already 'developed' areas rather than littering existing pristine areas, i.e., the Mojave (and other) deserts, National Forest clearings, and so on with solar panels.  Nature is not there to be continuously raped by us!  We've, collectively, done far too much of that already.    

Just my $00.02.  GOM

I'm not even keen on the expansive solar farms either. I think individual solar is the way of the future. Elon Musk has the right idea with solar shingles and battery banks in the home.

Greg,

While I agree with you, I have to be careful about biting the hand that feeds me. I worked on building 9 of them in the last couple years. Most on GOOD farm land :-(
