“…In order to maximize the connection capacity, one should adapt the generation profile to the load profile. Adaptation can be achieved by adapting the power of PV panels as well as the orientation of PV panels or by careful analysis of the wind profile [67]. Despite the energy balance, one need to consider dynamic issues, among which the most basic issue is a high variability in the load, which results in rapid voltage drops and flicker factor degradation.…”

Rail is the most efficient and low carbon means of transport, but efforts are still being made to improve the energy efficiency of this sector. In Poland, one of the elements of the implementation of the energy transformation in rail is the “Green Railway” program, which assumes an increase in the share of renewable energy sources (RES) in the power supply structure of the sector to 50% in 2025 and 85% in 2030, and ultimately, to 100%. An increase in energy efficiency leads to a reduction in financial costs, and also contributes to improving the environment and, consequently, to enhancing the economic and social benefit through a cost–benefit analysis. Energy consumption in railway operations is characterized (unlike in construction) by being repetitive. This energy consumption is produced in four areas: in the movement of trains; in auxiliary systems in the trains; in auxiliary systems in the infrastructure (lighting consumption of tunnels or sections of track, point heating systems, the signaling and communication systems, etc.); and in stations, workshops and by other consumers. The aim of this article was to review modern technologies using renewable energy sources in rail transport for traction and non-traction customers.

In recent years, Poland has implemented substantial changes to its energy mix, resulting in an increased proportion of energy production from photovoltaics (PV). However, the photovoltaic energy market’s development is determined by several factors, and still requires further analysis. Therefore, the study’s main objective was to comprehensively understand the PV phenomenon and its development in Poland. Furthermore, a PESTEL analysis was undertaken to assess the macroeconomic context of the photovoltaic industry in Poland. A systematic literature review methodology was employed to achieve this. The study’s principal findings identified a number of pivotal opportunities and barriers to PV development. The environmental benefits of CO₂ reduction and the economic advantages, including cost savings and subsidies, were identified as significant opportunities, as were social acceptance and enhanced energy security. However, obstacles to progress include outdated grid infrastructure, high investment costs, environmental concerns during the PV lifecycle, and political uncertainties. Technical challenges like grid stability and high battery costs also impede growth. Potential strategies for improvement involve better public awareness campaigns, enhanced self-consumption through storage systems, and optimised system placement. Addressing these factors could transform current neutral aspects into either opportunities or threats for PV deployment.
