Improved design and recommendations for street lighting in Gitega city

Abstract

The article discusses the possibility of using solar energy for street lighting systems in the city of Gitega, in the Republic of Burundi. Analysis of weather and climate conditions of the city was carried out and an effective street lighting system based on solar mini-power plants using an intelligent control system developed. Calculations of technical and economic efficiencies are made and the principle of operation of the developed system is described. A comparison of the methods of transmitting control signals and the performance of different types of lamps was made as well as an assessment of the battery discharge process. The different attachment types of solar panels to their supports were highlighted, the illumination received on a public space according to the installation height of the luminaire and the used LED power as well as the requirements in terms of illumination and brightness depending on the place to be lit were discussed. The system developed consists of two solar panels, connected in parallel, one battery and six LED lamps with adjustable power. At present, the problem of modernizing the lighting of public places and roads of regional and local significance in Gitega city remains relevant. With the aim of promoting clean energy and reducing energy consumption due to global concern about climate change, the use of modern, cost-effective lighting systems based on the use of LED technology and is one of the most dynamic trends in the world at present and in the near future for the well-being of the population.
