Solar Street Lights are well-designed to illuminate large areas with the highest intensity of light. These are used for commercial quality lighting systems, residential streets, parking lots and security lighting using high quality of solar systems. The most recent developments with regard to the technology behind solar street lighting have been in connection with LEDs. Firstly, these consume far less power than the older type of conventional sodium lamp. In addition, they have a much longer working life, better color definition and require smaller solar components than sodium lamps. It can be appreciated, therefore, that, in order for solar street lights technology to be efficient and cost-effective, a thorough and meticulous assessment has to be carried out, paying the utmost regard to information concerning solar radiation, the amount of sunshine prevalent and general climatic conditions in the relevant area.
