The feasibility of using photovoltaic panels to illuminate the entryway to an apartment building

The article considers the possibility of using an LED lighting system with a power source from solar modules in the climatic conditions of Siberia. The technical possibility of implementing an autonomous house lighting system is shown for example in the lighting of a residential five-story building located in Tomsk. The choice and justification of the neces-sary electrical equipment for solar panels was made. Calculations have been made for the energy consumption of the existing lighting system and a system with LED light sources from photovoltaic panels. The payback period of the project is determined. On the example of an autonomous sys-tem of interior lighting of an apartment building, conclusions were made about the feasibility and efficiency of using photovoltaic panels in the cli-matic conditions of Tomsk region
