Solar power generation road hollow slabs

Are hollow slab solar pavements cost-effective?

The cost-effectiveness of four typical solar pavement structural systems is evaluated, and a case study is presented. Results show that the net present value (NPV) and Levelized cost of electricity (LCOE) of Hollow slab solar pavements are the lowest.

Are solar pavements a good investment?

Case study Based on the literature review, in this section, the benefits from four full-scale solar pavements (Solar Roadways, SolaRoad, Wattway and Hollow slab solar pavement) are evaluated based on the investment cost per unit of electricity generated from the four kinds of pavements over their lifetimes.

Do driving Shadows affect the output power of solar pavements?

Due to the particularity of the use scenario of solar pavements, in addition to the occlusion of surrounding buildings and trees, it is also necessary to focus on the impact of the driving shadows formed during vehicle movement on the output power of solar pavements .

What is the LCOE of a solar pavement?

This value derives from the following considerations: the best solar pavement in terms of electrical output is Solar Roadways (4249 kWh/m 2 in 20 years), while the less expensive is the Hollow slab (NPV = 841 $/m 2). Under the hypothesis of coupling the best electrical output and the lower NPV, the LCOE would be 0.2 $/kWh.

Can a photovoltaic-thermal Road improve the service life of solar cells?

In order to enhance the comprehensive utilization efficiency of solar energy and improve the service life of photovoltaic cells, Xiang et al. combined the road flow tube heat collection technology into the solar pavement, and proposed a novel photovoltaic-thermal road (PVTR) system.

What are the three layers of solar pavement?

The solar pavement structure is mainly composed of three layers: surface translucent layer, middle-level photovoltaic layer, bottom protective layer. In order to make the solar pavement work normally, the three layers need to be coordinated.
