Sandpoint Town Square Home To First Public Solar Roadways Panel Installation (newatlas.com)

Two years after the Idaho-based company Solar Roadways exceeded its crowdfunding goal of $1 million for constructing roads that gather solar power, the company has completed its first public installation in the City of Sandpoint, Idaho, where there are 30 tiles currently installed. New Atlas reports: The 150 sq ft (14 sq m) installation in Sandpoint's Jeff Jones Town Square is made up of 30 SR3 panels. Where Solar Roadways' second generation prototype was a 36-watt panel, the SR3 is the same size but is rated at 48 W, made possible by replacing the panel mounting holes with edge connectors. The new units each include four heating elements to help keep the installation free of snow and ice and over 300 brighter, daylight readable LEDs with over 16 million available colors. Though now laid down and switched on, not everything went exactly to plan with the installation. Manufacturing difficulties meant that some of the SR3 panels were not fully operational at the time of the public reveal. The working units were placed in the center of the grid and surrounded by dead panels. Solar Roadways aims to swap out the non-working units as soon as possible. Sandpoint officials plan to allow the public to interact with and modify the light show soon, and future plans for the town square include free public Wi-Fi and the roll out of electric vehicle charging stations.

Do the math...

"free of snow and ice"

[networkBoy]

just how much snow and ice melting does it take to turn these into a net negative rather than positive generator of energy?

Even if they become energy consumers during snowfall, having a road that clears itself saves on fuel for plows and de-icing trucks, labor costs, chemical costs, potentially capital costs if fewer plows are needed, and probably other things I'm not thinking of. I mean, as long as the heating component actually works in practice and isn't wildly inefficient. Anyhow, even without snow cover, winter in the Pacific Northwest is not a great place to be trying to do solar, especially low to the ground where there is more likely to be more shade. In this environment, I'd consider any power generated by the road to be a nice bonus, and not the primary goal.

This is no roadway

This is a public place for pedestrians, bikes and market stalls.It's not even a road!

Call me again when they put it in an actual road where a few hundred semi trucks driver over it per day, all of them with gravel in their tires.

This is just a stupid publicity stunt.

It's a bit expensive...And for what?

[bobbied]

150 Square Feet of roadway for a cool $1 Million and nearly half of them don't work yet? Sounds like a pretty expensive road to me.

So, what exactly is the point of this little experiment anyway?
