Highway Photovoltaic Support

What is a highway photovoltaic system?

Schematic diagram of the highway photovoltaics (PV) system. Roofing highways with solar panels generates green electricity that is delivered to the grid to replace the electricity from fossil fuels, thereby contributing to CO 2 e emission reductions.

Why do we need government support for Highway photovoltaics?

In Asia and Europe, government supports are required because a large portion of the profits originate from social benefits (reduced traffic losses). Investments and returns of the highway photovoltaics (PV).

What is a highway photovoltaic (PV) investment?

Investments and returns of the highway photovoltaics (PV). (a) Investments required to realize a specific potential and the corresponding returns from selling electricity and reducing traffic losses over a 25-year lifetime.

Can solar panels be used in a roofing Highway?

Photovoltaic (PV) installations are a leading technology for generating green electricity and reducing carbon emissions. Roofing highways with solar panels offers a new opportunity for PV development, but its potential of global deployment and associated socio-economic impacts have not been investigated.

How much power does a photovoltaic Highway generate in China?

By 2020, the mileage of Chinese highway was 143,684 km and the area was 3,957 km 2. The installed capacity and power generation of PV highways in China are 700.85 GW and 629.06 TWh, respectively. Installing photovoltaic (PV) modules on highways is considered a promising way to support carbon neutrality in China.

What is the potential of a highway PV project?

Achieving the full highway PV potential could offset 28.78% (28.21%–29.1%) of the global total carbon emissions in 2018, prevent approximately 0.15 million road traffic deaths, and reduce US$0.43 ± 0.16 trillion socio‐economic burdens per year. Highway PV projects could bring a net return of about US$14.42 ± 4.04 trillion over a 25‐year lifetime.
