Phys.org reports on a pilot project in the Netherlands to generate power from solar panels in a bike path that has so far exceeded expectations:

The first six months of the pilot phase were successful, according to a SolaRoad press release issued earlier this month. The energy yield was beyond their expectations. Spokesperson Sten de Wit said they were surprised to see the level of success so quickly. Case in point: "The bike road opened half a year ago and already generated over 3,000 kWh," he said. "If we translate this to an annual yield, we expect more than the 70 kWh per square meter per year, which we predicted as an upper limit in the laboratory stage. We can therefore conclude that it was a successful first half year."

    It's still going to be cheaper and easier to put the solar panels OVER the road or path rather than UNDER it. That's what they're doing in South Korea and it seems to be working just fine. You can also put them on plenty of other government property -- reservoirs seem to be an excellent choice, as the panels operate at higher efficiency since you get free cooling. At least put some up on the roof of every government building. Once they've run out of space there, then it might make sense to start putting them in/on/along the roads.

    But really it's still going to be cheaper to go buy new property to build a solar plant on than maintaining solar roadways. Solar panels are gonna cost a few million per acre. Land is maybe a few thousand per acre. Land is not a significant part of the cost here. Probably around one tenth of one percent. So taking a HUGE hit on the reliability and maintenance costs of those panels in order to use less land is pretty stupid. Also building them in the roads means you have to use PV cells, and PV cells are not the best way to do solar. Buy a couple empty acres and you can use cheaper and more environmentally friendly mirror systems instead.
