What types of solar road lights you should have for highways?



No doubt a solar road light is a great idea and it is happening. It can ardently change how we complete the roadways and how to respond to climate change, and other advantages. Solar road lights reduce night accidents, gives security and police protection, improve the flow of traffic and boost business.

Demand for solar is increasing everywhere, landfills and parka pockets, and why shouldn’t we incorporate solar on roads? Solar road lights are increasingly getting popular all over the world, and some roads are even promising to charge electric cars while on the move.

The concept of the solar road was started in the Netherlands when it was set up for a bike path in 2014. Next was France to add another feather in its cap in January and the next five years it decided to install 1,000 kilometers of solar roads. In December of the same year, it started the solar road meant for cars in a Normandy village. The 0.6-mile route is covered with 2,888 meters of solar panels. German was next in a row.

China also opened a kilometer-long stretch of solar road in Jinan in 2017. The road contains insulating layer towards the bottom, photovoltaic panels towards the middle and transparent concrete on the top. The electricity that is generated by the panels could empower everything, and that includes street lights to signboards.

The solar roadways are a smart way towards our go green initiative while offering safe driving conditions. On the street roads instead of using usual dark grey asphalt, we can see blue-green hexagonal tiles, which has lane markings and traffic signs that are illuminated by LED bulbs. Julie and Scott Brusa conceptualize the concept of solar roads and proposed to create glass-topped solar panels that are rugged which means can bear big trucks, heavy traffic and can also create electricity. And not only this, these roads are anticipated to charge electric cars. LED’s are incorporated in the panels not only for marking roads but also for showcasing advertisements.

The roads can also be used for funneling melted snow from the solar panels inside the storage tank before sending to the water treatment center. Solar panels will be exposed to the sun so that these are heated enough to melt the snow. The advanced technologies like silicon solar cells and LED lighting are also used to design the road and to withstand the weather and road conditions.

In China, the leaders in a solar road development project are Pavenergy and Qilu Transporation. Pavenergy is creating panels for Qilu which is a state-owned highway construction company. The panels are created of a complex polymer that is similar to plastic but has more friction than a conventional road surface system but which could be adjusted. It’s also found that blue silicon of solar cells, which is an electricity-generating component, can face many tons of weight.

How the Solar Roadways Designed?

The solar roads contain a series of interconnected panels with each panel consisting of three important layers. The topmost layer should be of great strength and rough enough to offer great traction for vehicles, yet can allow sunlight to penetrate to the solar cells which are situated underneath. The solar roads also have a strong glass with a slightly textured top which can cause traction which is better than asphalt and can easily bear the weight of the truck.

The middle layer constitutes the solar panels and a microprocessor board that controls the LEDs, which could illuminate the roads and gives traffic information. Microprocessors allow great features for instance; each panel can analyze the condition of the road and can convey the same to the driver. The panels can also convey information by quickly notifying in case there is damage to any one of the panels. The microprocessors also manage the road temperature that helps in melting of the snow in winters.

These solar roadways are no doubt the most innovative concept and if incorporated could become one of the best go green initiative.

Summary: Solar Roadways is a new big thing and a revolution in the road industry. Governments of many countries of the world are trying to make it a reality.  No doubt initial cost would be huge but the initial outcome would be positive. It would not only be the road of the future but a best energy conservative mechanism.
