Analysis of the use of photovoltaic panels on the roof and walls of passenger carriages to reduce electricity consumption

The article discusses the possibility of using solar panels on passenger rail carriages to reduce electrical energy consumption. In the first part of the paper, the possibility of using solar energy under Polish location conditions is discussed and the general parameters of selected solar panels are presented. In the following sections, the possibility of installing solar panels on a railway carriage is analysed. A theoretical evaluation of the energy gain per year and per months is also carried out, taking into account power losses. Finally, the topology of photovoltaic networks is outlined, including the choice of energy storage.
