Abstract: Solar energy is a renewable, non-polluting energy, and it is available all over the world. That makes it an excellent alternative to the use of fossil fuels, contributing to the care of the environment. The main of this project is to take advantage of this energy for tunnel lighting. The use of solar panels adapts perfectly to the necessity of regulating the lighting in function of the external luminance. Because of the sight adaptation period, it is necessary to regulate the illumination power at the entrance of the tunnel depending on the external light. Solar panels make it considerably easier, since when it is necessary to increase the power, they obtain more energy. The base energy is obtained from the grid, and the solar panels provide the power needed to achieve this increase of illumination during the day. Besides, using this system there is no need of energy storage of any kind. To perform the calculations, we will base on the data of the Negron tunnel (Principality of Asturias). Maximum power.
