THE POWER OF SOLAR ENERGY
From portable units to large-scale structures, these self-contained systems offer customizable solutions for generating and storing
Installing solar photovoltaic (PV) systems on train rooftops can reduce energy costs and emissions and develop a more sustainable and ecological rail transport system.
For a typical medium-sized railway station, the installation of solar panels requires an initial investment of €200,000-400,000, with a payback period of 6-8 years. Government incentives and EU sustainable energy programmes significantly improve the financial viability of solar railway projects.
The direct integration of solar energy in rail transportation mostly involves utilizing station roofs and track side spaces. This paper proposes a novel approach by proposing the integration of photovoltaic systems directly on the roofs of trains to generate clean electricity and reduce dependence on the main grid.
According to Figure 11, the solar panel power output (59,370 kWh) can meet 9.8% of the entire demand (607,083 kWh) of train auxiliary systems per year. It is evident that this usage is related to the auxiliary power of trains. The calculated amount is specific to the type of train considered and the path selected for the case study.
