Wow. Solar roadways are really going to happen notwithstanding all the naysayers!

cheers Peter

Considering the low human labor cost in China (which is inevitably required when something breaks and someone has to fix it) and massively over stock solar panels and PV manufacturing capacity, I think it may have a shot in China, though how feasible remains unknown.
This is more like a public stunt and social stabilization attempt. Chinese government made a huge gamble on PV, and after spending hundreds of billions on PV industry and various climate and political international public stunts, global PV market didn't take off.
Chinese government has to find a way to sell over stock PV cells and keep the factories running otherwise the lobbyists and unemployed formal PV factory workers will not be easy to deal with. In another word, this can be an attempt to use taxpayers' money to make PV lobbyists and their employees happy.
But at least it set one thing correct: it's not a main energy source, instead, its generated electricity will be used to power itself to provide guidance, wireless hot spots and smart traffic signage services.

The following quote should cause Dave to tear his hair out.

"Solar road initial investment than ordinary highway high of about 30%, but from the point of view of life, solar road for more than 20 years of life and less maintenance, making it the year cost lower than ordinary highway, in addition, it also has functions such as snowmelt and wireless charging etc.."

I think it's more a PR move towards foreigners. To use PV panels it makes far more sense to just plump them down in a desert and build a modern aluminium smelter near by designed for PV supply (ie. intermittent). That will minimize your losses.

PV are the minority cost in glass roadways, it is one of the most expensive ways to use up surplus PV. It would be cheaper to just recycle the panels directly.

For best results, the vehicles will need to be transparent also.

solar road for more than 20 years of life and less maintenance,

  20 years?   :-DD  The Chinese panels that they're selling in this country don't last for three years and the Chinese built synchronous inverter/controllers don't even last that long. It's no surprise that no one is buying them!   IMO Chinese solar panels would be most useful if someone ground them up and made pavement out of them.

   Somebody is China is serious kidding themselves if they think that those panels are going to last for 20 years!  This project smells of BS from top to bottom!

Bullshit. Most PV panels deployed worldwide are made in China and are high quality with 20-30 year warranties standard. 

Chinese inverters are another matter...

And of course any solar panel is not going to last long embedded in a roadway nor will the power output be anywhere near optimal. So despite high quality Chinese solar panels, solar roadways of any kind remain an ill conceived boondoggle.

Solar roadways are the answer..... right?
