Cement road solar panels photovoltaic power generation

Is photovoltaic pavement a viable energy harvesting technology?

Recommendations for its future development are proposed in six aspects. As an emerging energy harvesting pavement technology, the photovoltaic (PV) pavement, which combines mature photovoltaic power generation technology with traditional pavement facilities, can make full use of the vast spatial resource of roadways.

Is solar pavement a good choice?

However, the solar pavement showed relatively superior performance in other aspects. Based on measurement and analysis results, it was recommended to add a new layer of solar rubber pavement to enhance strength parameters and power generation. Some enterprises also launch some products of PV pavement.

What is photovoltaic pavement?

To deal with this issue, the concept of photovoltaic (PV) pavement is emerging , . It regards the modified photovoltaic modules as one part of the road structure, equipped with the inherent function of electricity generation and vehicular traffic support. The core advantage of this technology is the non-extra land occupation.

Can a pavement integrated photovoltaic pavement system generate electricity?

Li et al. proposed a pavement integrated photovoltaic pavement (PIPVT) system and developed its relevant mathematical model . Based on the real meteorological data in Shanghai, the simulation results showed 0.62 kWh of electricity and 1.36 kWh of heat could be generated by two mentioned PIPVT modules on a typical sunny day.

How can solar pavement reduce the temperature of photovoltaic cells?

The system can reduce the temperature of photovoltaic cells of solar pavement by 4.15 °C, and its total energy efficiency is 3.95 times that of a single solar pavement, which can improve the photoelectric conversion efficiency of solar pavement and prolong the service life of the system.

Which solar cells can be used in PV pavement?

Moreover, some emerging solar cells, such as dye-sensitized solar cells (DSSC) , organic solar cells (OSC) , and perovskite solar cells (PSC) , might be promising and competitive in the PV pavement field with lower cost in the future.
