Public lighting for public spaces and roads are a necessary evil. They provide road traffic safety and heighten our sense of security on the streets at night.
Street lighting is one of the major components of the total energy consumption in municipalities.Nowadays, implementation of solar-powered street lights may at some extent alleviate the power burden on the system.
Solar street lights are raised outdoor light sources, which are powered by PV (photovoltaic) panels. The solar cells in the panel seize the energy from the sun during the day. That energy is converted into electricity and stored in the battery. Once sunlight starts to fade and the solar panel voltage drops lower than 5 volts, LEDs progressively start to light on. They will remain on throughout the night, consuming the energy stored in the battery.
Advantages of Solar Street Lights
Solar street lights are independent of the utility grid resulting to fewer operation costs. And they require less maintenance than conventional street lights. They also have lower chances of overheating.
Since solar wires do not have external wires, the risk of accidents is minimized. A lot of times, accidents happen to the personnel who fixes the street light. These can include strangulation or electrocution.
Solar street lights are environment-friendly as its panels are solely dependent to the sun hence eliminating carbon footprints contribution. Some parts of their systems can be easily carried to remote areas, which makes it more efficient and easy to solve lighting problems.
Disadvantages of Solar Street Lights
Solar street lights require higher initial investment compared to conventional street lights. This is actually the main reason why most people are giving up using solar street lights. They consider the money they are required to spend without realizing the long-term benefits and the longer life cycle of solar street lights.
Rechargeable batteries must be replaced a few times within the lifetime of the fixtures. This adds up to the total lifetime cost of the lighting system.
