How efficient is a solar road?

Assigning a certain point for each parameter, the authors classified the efficiency of the solar road; the score ranges from 57 (ideal rating for the installation of the pavement) to −9 (not suitable).

Can photovoltaic panels be placed on a slope of a road?

Layout of photovoltaic panels on the south-facing slope of the road. Similarly, the optimal tilt angles of PV arrays on the slopes of roads in typical directions could be simulated and derived using PVsyst7.2, and they are shown in Table 2. However, the desirable PV array placement may not always be in the same orientation as the target slope.

How to build a solar roadway?

The construction process involves furnishing and wiring the base plate, placement and connection of solar photovoltaic cells with the previously placed layers, and finally, the positioning of the glass layer. A solar roadway is not suitable for heavy vehicles since it cannot withstand very heavy loads.

What is a solar roadway?

A solar roadway is a street surface that produces electricity. It consists of a glass layer, an electronic layer, and a base plate layer. The construction process involves furnishing and wiring the base plate, placement and connection of solar photovoltaic cells with the previously placed layers, and finally, the positioning of the glass layer.

Can a solar PGP assessment be performed on a highway section?

By subtracting the energy loss caused by temperature changes, the operation of inverters, and the PV modules’ performance decay, the actual PV PGP could be obtained. Finally, a case study of the solar PGP assessment of a 1.97 km long highway section is provided, and the feasibility of the proposed method is verified.

Are solar roads economically attractive?

In summary, the solar roads are not yet economically attractive. Based on the case study, the efficiency ranges between 12.1 and 15.6%. This is due to the low efficiency of the solar cells technology and the opacity of the top layer.
