Lets check up on Progress of Solar Roadways

Solar powered parking lot concept gets huge grantScott and Julie Brusaw are ready to show the world that we could build solar-collecting, energy-producing, safe and smart roadways.
And by ready, they mean everything is in place. The Sagle, the Idaho couple’ s Solar Roadways enterprise, received a $750,000 Small Business Innovation Research grant from the federal highway administration last week to fund an ambitious second phase of their project that will result in a complete and functioning solar parking lot outside of Brusaw’s lab.
Solar Roadways had already made inroads with the highway administration when the concept gained serious traction at the GE ecomagination competition last year.
Now Solar Roadways is getting some attention, and it’s becoming easier to find needed resources, Scott Brusaw said.
The greatest roadblock to seeing the idea through to the end has been finding the right glass to cover roadway solar panels, Brusaw said. The glass has to be clear in order for the panels to work, but textured enough to give drivers traction.
“We found a glass sidewalk panel in New York City,” Brusaw said. “It’s perfect.”
He said the panel manufacturers know what they’re doing and have created a glass panel designed to keep pedestrians safe in all weather conditions that’s still perfectly clear.
The strong, textured glass completes Brusaw’s vision, and he now has everything he needs to build a solar parking lot.
But having the glass nearly in his hands has led him to another idea, a way to make the solar roadway concept even more amazing and useful.
“We’re going to work together on forming prisms in the glass,” Brusaw said. “We think we can concentrate the sun onto the solar panels and get greater efficiencies.”
Brusaw said he thinks the money from the grant should be enough to finish a prototype parking lot—just exactly enough with no room for errors or experimentation, he said.
For that reason he’s still fundraising to try to supplement the grant money and allow a little wiggle room in the prototype development.
“If everything were to go perfectly, we could be finished in two years,” Brusaw said of the prototype parking lot. “But that’s if everything were to go perfectly. I expect to run into a few problems.”
Years ago, when the phrase "Global Warming" began gaining popularity, we started batting around the idea of replacing asphalt and concrete surfaces with solar panels that could be driven upon. We thought of the "black box" on airplanes: We didn't know what material that black box was made of, but it seemed to be able to protect sensitive electronics from the worst of airline crashes.
Suppose we made a section of road out of this material and housed solar cells to collect energy, which could pay for the cost of the panel, thereby creating a road that would pay for itself over time. What if we added LEDs to "paint" the road lines from beneath, lighting up the road for safer night time driving? What if we added a heating element in the surface (like the defrosting wire in the rear window of our cars) to prevent snow/ice accumulation in northern climates? The ideas and possibilities just continued to roll in and the Solar Roadway project was born.

In 2009, we received a contract from the Federal Highway Administration to build the first ever Solar Road Panel prototype. During the course of its construction, we learned many lessons and discovered new and better ways to approach this project. These methods and discoveries are discussed throughout this website. Please enjoy and send us any questions that you may have. This YERT video is featured in their full-length documentary, now being screened across the U.S. For a screening or presentation near you, click on the following "YERT plate":


After successful completion of the Phase I SBIR contract, we were awarded a follow-up 2-year Phase II $750,000 SBIR contract by the Federal Highway Administration beginning in 2011. With this award, a prototype parking lot will be built and then tested under all weather and sunlight conditions.

The heart of the Solar Roadway™ is the

Solar Road Panel™

The Solar Roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels that collect energy to be used by our homes and businesses. Our ultimate goal is to be able to store excess energy in or alongside the Solar Roadways. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity. This, in turn, cuts greenhouse gases literally in half.
Solar Road Panel

Solar Road Panel

Each individual panel consists of three basic layers:

Road Surface Layer - translucent and high-strength, it is rough enough to provide great traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. It is capable of handling today's heaviest loads under the worst of conditions. Weatherproof, it protects the electronics layer beneath it.
Electronics Layer Contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element. No more snow/ice removal and no more school/business closings due to inclement weather. The on-board microprocessor controls lighting, communications, monitoring, etc. With a communications device every 12 feet, the Solar Roadway is an intelligent highway system.
Base Plate LayerLayer - While the electronics layer collects energy from the sun, it is the base plate layer that distributes power (collected from the electronics layer) and data signals (phone, TV, internet, etc.) "downline" to all homes and businesses connected to the Solar Roadway. Weatherproof, it protects the electronics layer above it.
