EEVblog #1047 – Solar Roadways FINALLY BUSTED! (Colas Wattway)

Dave finally puts an end to the idea of Solar Roadways. We have the test results of the world’s biggest solar roadways project, the 1km long 336kW Colas …

  1. Instead of solar roads, they should build electric roads that supply power to EV's. I wouldn't have a clue what would be the best method, would induction be possible?

  2. i see the point you make, but about the cost, i disagree with you. first: its a prototype situatuation.. if the can do it in big dimensions, and if the cost for solar panel drops (like all technological things, they will drop) the cost effiency will be better. And its not fair to compare it to a pure solar panel installation.. you must compare it also to the cost to a normal road construction with concret oder asphalt. a normal streat in germany costs around 300`000 euro for one kilometer. at the moment, and for a pilot project, its absolutly not efficient, thats right.. but, if the the concept will be adoptet in a much larger scale, the production costs will shrink (because of mass production) and the installationcost also (because of specialiced machines and tools, that companies will made for such a scenario). and there are other points: a normal solar farm needs space, space that then is wastet for other usages like bilding houses, grow food or stuff like that.. the land must be buyed, thats expensive.. the "land" on roads are allready buyd, so the prise for land falls flat. And, especialy here in europa, the cost for electrical power is massiv, and it will rise, because of focusing more on renewable energy instead of oil, charcoal and atom. if you count everyting together.. and the fact something like that can help to save our invoirment, its in a vew year no longer "that expensive" as it is now

  3. Dave, I agree with your calculations but I believe you missed some important data. You should consider the cost of land that you don't need to purchase for new solar commercial applications and you should consider the road maintenance savings. Cheers

  4. Not only is the roadway outrageously expensive, the figure for the commercial farm seems high too. For a $1.50 a watt you can get panels installed for homes in the US. Solar has gotten to be such a big business in this area that the local power company convinced the Chinese to build a Florida solar panel making plant to supply themselves with panels. Instead of 300 KW they are adding about 300 MW per year in Florida. Disclaimer: While I don't own FPL/Next Era Energy stock, my father worked for the company for 18 years.

    It looks like the French would have been better off installing supports along the roadway and putting panels above the road. That also would have helped keep the drivers and road cooler and in the winter, less snow on it. Flat mounted panels are not bad in all locations and the closer to the Equator you are, the better they do.

  5. For full size vehicle traffic this is probably not too durable, but I can see it last if you use it for sidewalk or bike lanes. It will be expensive, but when has expense stopped environmentalists.

  6. Wow this FOOKINFG idiot is totally missing the fooking point, these solution providers dont claim it to be the cheapest or most cost effective solution only an alternative means of NOT USING GREEN FIELD LAND TO INSTALL SOLAR FARMS we need the land for agriculture especially in countries that are not that big

  7. Google street view hasn't caught up with it, but the promotional videos suspiciously show some sort of new crash barrier as part of the installation … – pretty certain this is where it's been installed :- 48.586341016, 0.646915764578

  8. canada is getting in on this action now "The City of Prince George has partnered with YCS Holdings Ltd. who have installed a section of solar-panel road in the parking lot.

    The segment of Wattway solar-panel pavement connects to City Hall reducing consumption of energy and allows them to supply power to other areas, such as vehicle charging stations.

    Chris Simons, Division Manager, says this is just the beginning of what he hopes a future expansion.

    “Right now we are in the research and development stage so we want to trial it here and see how it stands up to Northern BC interior winters and it could be an opportunity for projects going forward to utilize this technology.

    Simons says with this installation, Prince George is making headway in renewable energy.

    “This is the first one in British Columbia and it’s the first one in a public environment in Canada.”

    The panels are installed without having to destroy or rip up the existing roads and can stand the weight load of an 18-wheeler truck."

  9. Just an answer to many comments below ROADS ARE NOT FLAT all roads have a camber, a slope from the middle going downwards to the kerb and drains, but where solar is concerned they might as well be,,
