In 2014, the northern city of Holland established the first road g Rasmani solar panels in the world. After 6 months of testing, engineers said the system was even better than expected.
This road is a bike path, with a total length of about 70 meters. Embedded in the cement plate crystal silicon solar panels, convert solar energy into electricity, and send it to the power grid, for the supply of street lamp, traffic signal lamp or nearby homes. The pavement surface is a protective effect of the glass, can withstand the weight of 12 tons of heavy fire truck.
Engineers said the 70 meter long solar panels road power generation 3000 kwh, enough for a family of the year with electricity. Laying the road SolaRoad sten, a spokesman for the de Wit said: "if we calculate for the year as a whole as the standard, we think that its annual per square metre of 70 kW generating when." This shows its great potential, if we will have all the roads are covered with solar panels, how much power can be generated?
It is this thinking led to the Roadways Solar project on the Internet is being hype, the purpose of the congregation raised plans to use solar panels cover the road, for the u.s.. However, Holland has become the first implementation of this creative country.
Engineers spent 5 years developing the system, which is very durable. Kremer Imtech, a consultant for the technology company Jan-Hendrik renewable energy system, said: "if there is damage to the battery board, be hidden or dirty, only need to be replaced separately."
During the 6 month of the test, the road has more than 150000 cyclists through. So far, they have only found one failure. A small piece of coating is layered due to temperature change. SolaRoad team is now trying to improve the coating. "We have developed a new coating that is sufficient to deal with traffic loads, and to provide friction to the vehicles," said Stan SolaRoad,'s parent company and Klerks TNO, a research firm in Holland." ""
The researchers designed the panels not only for more light, but at least 20 years, similar to the life of a roof solar panel. The potential of this technology is amazing, not only the highway can produce enough electricity to supply local residents, but also for other lighting projects.
In 2014, Dutch design studio studio roosegaarde has proposed highway design of solar panels, that absorb solar energy during the day, at night by famous painter Vincent Van Gogh's "starry night" (starry starry night) made of LED lights, guided by bike.
SolaRoad is now working with many local governments in Holland to promote the technology to more places. In addition, they also signed a similar agreement with the United States, California government.
