Can charge can melt snow, the first paragraph of the "solar" highway opens
2017-12-29

December 28 afternoon, the world's first photovoltaic highway is about to open to traffic in Jinan, as the latest "black technology", this road in addition to the general access features, you can also achieve solar power generation, electric vehicles driving on the road charging Features. It can be said that with such a road, there will be a positive impact on the further popularization of new energy vehicles.


It is understood that the trial section to be opened to traffic in the afternoon will be 1120 meters in length and 1080 meters in length. The main and lanes will be laid. The main traffic lane width of 3.75 meters, of which 3 meters wide photovoltaic pavement. Emergency lane width of 3 meters, of which 2.48 meters wide photovoltaic pavement. The total net net area of photovoltaic pavement is 5,875 square meters, the peak power of distributed grid-connected power generation capacity is 817.2 kilowatts, and the estimated annual generating capacity is about 1 million kilowatt-hours. The design load is based on the current national highway standards. The design service life refers to the asphalt pavement design code standard for 15 years. The design carrying capacity is 24 million ESAL equivalent standard axle loads. Design life, road performance indicators are higher than the existing asphalt concrete pavement.


In terms of charging electric vehicles, photovoltaic road surface is the best carrier for mobile electric vehicles in the future. The wireless charging technology of electric vehicles is improving day by day. The state is formulating relevant technical standards and norms. In 2018, it is believed that there will be commercial products available.



At present, the test section has achieved power generation and integration into the national grid. The government has promulgated many policies on solar green energy and has always encouraged and developed a green light for green energy.


From the analysis of economic profits, taking Shandong Province as an example, the province has opened 5,700 km of expressway, with a total area of 66.96 million square meters of emergency parking belts and outbound lane. After laying pavement photovoltaic equipment, the annual generating capacity is 15.6 billion kWh. 15.2 billion yuan of annual emission reduction of 15.5 million tons of carbon dioxide emissions, emission reduction profits of 4.6 billion yuan, direct profits of 19.9 billion yuan, such as laying all roads, the profits are more impressive.



In terms of social profits, PV pavements make use of the existing road resources without additional land occupation and pollution discharge, providing high-quality and clean energy to cities and residents along the route, which is of far-reaching significance for energy conservation and emission reduction and improvement of energy structure in China. From the analysis of economic profits, taking the province as an example, the province has opened 5,700 km of expressway, with an area of 66.96 million square meters of emergency parking belts and lateral lane. After laying pavement photovoltaic equipment, the annual generating capacity of 15.6 billion kWh, power generation profits 15.2 billion yuan of annual emission reduction of 15.5 million tons of carbon dioxide emissions, emission reduction profits of 4.6 billion yuan, direct profits of 19.9 billion yuan, such as laying all roads, the profits are more impressive.


As a new format that relies on traditional expressways, the photovoltaic road surface has already achieved the initial integration of the two major areas of transportation infrastructure and photovoltaic new energy sources. The future mainly to carry out the following operations: First, self-use and grid-connected power generation. On the one hand, it can solve the electricity demand of service areas and tunnels along expressways, reduce the operating cost of expressways, and on the other hand, "where the roads lead to where the light is brought," and also meet the electricity needs of business residents along the highway, The implementation of such strategic plans as the "Belt and Road Initiative" will bring greater social profits.


Second, electric car wireless power supply. In the future, by utilizing the power supply along the photovoltaic pavement and the mature wireless charging technology, the photovoltaic pavement will become a shared vehicle non-contact energy supply platform and a new profit point for the photovoltaic highway operators.


Third, automatic piloting service. As a traditional value-added service of the highway, the long-term relying on the photovoltaic power support and the built-in information network to achieve the vehicle information exchange and energy interaction, the establishment of an intelligent transportation system to achieve auto-driving guidance, car networking and society as a whole Vehicle network scheduling.


Fourth, the relevant quality assets listed. Through continuous technological innovation, the application scenarios of photovoltaic expressways are constantly expanding and the construction costs are continuously reduced. In the future, the upstream and downstream photovoltaic equipment manufacturing, design and construction as well as pavement assets can be packaged and listed as high-quality assets to obtain capital market returns.


The test section has an annual generating capacity of about 1 million kWh and has achieved the functions of providing electricity supply for street lamps, electronic information boards, deicing salt sprinkler facilities, tunnels and toll gates, and power grid access. The upcoming functions are integrated with electronic signage, wireless mobile car charging, snow melting on the road, Internet coverage, big data integration and analysis.
