Unit06  Each of the new panels features PV cells and circuit boards, 128 programmable LEDs, a heating element to help deal with ice and snow, and are topped with ‘super-strength’ textured glass (which has exceeded expectations in load, traction and impact resistance testing).  “Half of our prototype parking lot is mono- crystalline, while the other half is poly-crystalline,” Julie Brusaw explained. “The parking lot is equiva- lent to a 3600-watt solar array. The power collected is dependent upon the amount of sun- shine received. So as with all solar, it will produce more in some parts of the country and world than others.”  “We’ve moved power and data cables to a cable corridor alongside the road/parking lot,” she con- tinued. “This provides the power or data companies with easy access. It will give the cables a home and eliminate the need for overhead wires that are unsightly and subject to ice or breakage. Our system can also eliminate cell phone dead spots by installing a ‘leaky’ cable in the cable corridor. Our corridor can be a home for all kinds of cables including TV, fibre optic for high-speed internet, phone cables, etc.”  Currently, some 69 percent of the layer directly under the glass of each hexagonal unit is made up of photovoltaic cells, but that will increase to 100 percent prior to commercial production. Before that can happen, though, the Solar Roadways project has hit the crowdfunding platform Indiegogo to help raise enough money to hire a team of engineers and other professionals, streamline the production process and move into manufacturing proper. 0 What functions will the solar panels fulfil?
