Roof Tops or Highways ?

To generate 1 Kw of solar power you need , approx. 10 Sq Meter ( 100 Sq ft ) of roof top

So , if you want to generate 817 Kw , you would need 8,170 Sq Meter of flat roof

But the Chinese have just managed to generate 817 Kw , using only 5,875 Sq Meter space

And , that too , on the highway surface  !  In 28 % less area as compared to Roof Top

But the breakthrough has nothing to do with mere reduction in area

It brings the World , one step ( - actually , one Km ) closer to :

Roads with solar panels are no surprise. But a road with built-in wireless charging systems for electric vehicles and other sensors for drones is surely taking things to the next level and looks like China has successfully achieved that feat.

According to Xinhua, China has successfully tested its first photovoltaic highway based on home grown technology, in the country’s eastern Shandong province.

The road is constructed using solar panels which have a thin sheet of clear concrete on top, protecting the surface. The panels were built to transfer energy to electric vehicles passing on top of them.

 The one kilometer-long segment of the solar-powered highway covers a surface area of 5,875 square meters.

The special section has three layers. The bottom is an insulator to prevent moisture from getting to the photovoltaic devices in the middle. At the top is the protective, transparent concrete layer.

The tested segment of the highway can generate 817.2 kW of power and is expected to generate 1 million kWhr of electricity each year.

The electricity generated through this will be connected to China’s national power grid.

China becomes the second country to construct a photo-voltaic highway.

In late 2016, the world’s first photovoltaic road fitted with solar panels debuted in France.
