Street lighting is a key element ensuring the safety of motorists and pedestrians. The development of LED light sources and their high luminous efficiency have meant that currently available LED luminaires, in addition to traditional power from the power grid, can be autonomously powered by solar energy, wind energy, or a combination of both. This article presents the results of simulation studies related to a one-year analysis of the operation of solar-powered street lighting luminaires. In the first stage of the study, the luminaires were selected with the power requirements of the EN 13201:2015 standard for the assumed lighting class. Next, simulation studies were conducted for an actual set consisting of a street lighting luminaire, photovoltaic panels, batteries, and a charge controller, related to the operating conditions of the LED luminaire. Individual months of the year in Poland were analyzed to assess the self-sufficiency of the energy generated to power the LED road luminaire, particularly during winter.
