Abstract

Public lighting is an essential service in today’s cities, towns, and highways, including improving public safety and reducing traffic accidents. Public lighting could consume up to 40% of the energy budget of the local governments. Therefore, the technical innovations related to public lighting always bring significant value to municipal governments. In Vietnam, the public lighting in big cities account for 25% of the total power consumption. The solutions to reducing electricity consumption for public lighting are also of interest to domestic and foreign organizations, including the use of on-site energy such as wind and solar energy. In this paper, on the basis of the current state of the public lighting system and the potential of solar energy in Hanoi, the authors have roughly calculated the technical and economic efficiency of power supply solutions using solar energy in public lighting. The proposal of solving the power supply problem, by using solar energy in public lighting in Hanoi is another result of the paper.
