Free Power From Freeways? China Is Testing Roads Paved With Solar Panels

Free Power From Freeways? China Is Testing Roads Paved With Solar Panels

Because roads run through and around cities, the electricity could be used practically next door to where it is generated. That means virtually no power would be lost in transmission, as can happen with projects in outlying locations. And the land is essentially free, because roads are needed anyway. Roads must be resurfaced every few years at great cost, so the installation of durable solar panels could reduce the price of maintenance.

Very cool idea!

Great idea. Putting solar cells where they'll get run over, dirty, oily, that won't degrade their performance.

Free Power

Solar roads are also more expensive than asphalt. It costs about $120 a square meter, or about $11 a square foot, to resurface and repair an asphalt road each decade. By comparison, Pavenergy and Colas hope to be able to bring the cost of a solar road to $310 to $460 a square meter with mass production.

Free? LOL!

And when your paid for the energy the solar road produces?

It still won't be free.

It is for those that pay for the road.

They're hoping to bring the cost down to $310/square meter.

That's not free power.
 
An alien race shows up and says "we've got a free limitless pollution free energy source for you".
"How do we get it? Drlling? Mining? Do we need explosives and have to risk thousands of lives?"
"No we'll beam it to you from our planet, you just have to build collectors for it."

And that is what solar power is.

An expensive, unreliable source of intermittent energy. Sweet!!

Where do you get your cheap, reliable, uninterrupted solar power?

The cost is paid by those that buy power.

What I produce and don't use is sold back to the grid reducing my bill to close to zero.

How much does it generate? How long does it take to recover the extra $190-$340 per square meter cost?

Edit: And a solar road can produce about $15 a year worth of electricity from each square meter of solar panels. So it could roughly pay for itself, compared with asphalt, over about 15 years.

So, with an overnight interest rate of about 5%, your extra (they hope), $190 expense, gets paid off in 20 years, longer if rates rise. Hmmmmm…..are they expected to last 20 years?

Doesn't answer the question.

Sure it does. You sell energy to maintain the roadway.

Maintain? You haven't even repaid the cost of the road.
