Solar street lights are powered by the sun which eliminates electricity costs but require regular maintenance to ensure optimal operation. LED street lights use watt bulbs and typically consume fewer watts than traditional HPS (high pressure sodium) or metal halide lighting solutions.
Solar powered street lights require a pole with an integrated photovoltaic panel to generate electricity during the day, while LED streetlights connected to electrical grids draw power from a utility company. The installation costs for these poles range greatly depending on their height and design requirements.
Light power consumption depends on the type of LED street light used as well as its operational hours. For example, high power LED lights can require up to 200 Watts per hour while some low wattage models may only use 10 watts per hour.
Typically, lights on residential roads are lower power than those on main roads. In simple terms, the electricity consumed by an 'average' light can cost between £25 and £65 a year. How are street lights supplied with electricity?
