JINAN, China-- On a smoggy afternoon, huge log providers and oil tankers thundered down a highway and hurtled around a curve at the bottom of a hill. Only a single, unreinforced guardrail stood in between the traffic and a ravine.The route might make for difficult driving under any conditions. Specialists are viewing it for one feature in specific: The highway curve is paved with solar panels."If it can pass this test, it can fit all conditions," said Li Wu, the chairman of Shandong Pavenergy, the business that made the plastic-covered photovoltaic panels that carpet the road. If his item fares well, it might have a significant influence on the renewable resource sector, and on the driving experience, too.
ago. Road home builders in China even wish to create solar roads that can wirelessly recharge electric automobiles running on them, replicating a current American experiment. China's leaders in solar road development are Pavenergy and Qilu Transport
. The 2 business are collaborating here in Jinan, in Shandong Province, with Pavenergy making panels for Qilu, a big, state-owned highway construction and management company that runs the highway.The surface area of these panels, made of a complex polymer that looks like plastic, has slightly more friction than
a traditional roadway surface, inning accordance with Zhang Hongchao, an engineering professor at Tongji University in Shanghai. Teacher Zhang, who helped establish Pavenergy's roadway surface, stated that the friction might be changed as needed during the production procedure to ensure a level of tire grip equivalent to that of asphalt.The place of the solar roadway here, on a long curve at the bottom of a hill, was not Pavenergy's very first option. The website was picked because of its proximity to an electrical energy substation, making sure that it would be connected to the grid. China is including solar and wind energy sites so fast across the country that power generation projects further from substations in some cases deal with delays of years in getting connected. Photovoltaic panel, shown going through tests, would likely need to be changed less typically than asphalt roadways. It remains uncertain whether they would be able to take the pounding of millions of tires each year for more than a decade.Credit Giulia Marchi for The New York City Times The primary Western rival to Pavenergyand Qilu is Colas, a French road-building giant that has actually established 25 speculative solar roads and parking lots, primarily in France but likewise in Canada, Japan and the United States. The most significant of Colas's solar sites, a country roadway in Normandy that opened a year and a half back, has only half the area of the brand-new solar highway in Jinan. Colas has been wary of putting solar panels on high-speed
roadways like the Chinese highway because of security issues; Teacher Zhang stated the panels were totally safe.Still, a litany of impressive challenges means the broad release of solar roads is a long method off.For one, they are less effective than rooftop solar panels at converting the sun's light into electrical power. They lie flat, and are periodically covered by automobiles, so photovoltaic panels on a roadway produce only around half the power that rooftop ones slanted toward the sun do.Solar roads are likewise more pricey than asphalt. It costs about$120 a square meter, or about$11 a square foot, to resurface and repair an asphalt road each decade. By comparison, Pavenergy and Colas hope to have the ability to bring the expense of a solar roadway to
$310 to$460 a square meter with mass production.

And a solar road can produce about$ 15 a year worth of electrical energy from each square meter of photovoltaic panels.
millions of tires each year for more than a decade, or whether they may be stolen.Several square feet of solar panels vanished less than a week after they were installed here in late December, raising worries of theft or even industrial espionage.Local cops officers, facing criticism for not offering better security, said that the panels must have been crushed into small pieces and scattered by heavy trucks.
