Solar street lights feature an elevated light source that is powered by solar cells.
The panels are integrated in the pole or fixed on the structure.
The solar panels recharge a battery which powers an LED or fluorescent light at night.
The following are some examples of
The majority of solar lights use the voltage of the solar panel to determine and switch on or off outdoor lighting.
Solar streetlights are on all night long.
Solar streetlights may be used for longer than one night in the event that the sun is not visible for a long duration.
The lamps of older models were not fluorescent or LED. Solar lamps in areas with high winds typically have flat-paneled solar panels. They can then better cope with the wind.
For battery management, modern designs use wireless technology.
This allows street lighting to function as a system, in which each light can turn on and off the entire system.
Components
Four primary components compose solar street lights:
Solar panel
Solar panels are an essential component of solar street lamps,since they are able to convert solar energy into electricity that can be used to power lamps. Solar street lights are commonly ma-de, and there are two kinds of panels, monocrystalline and polycrystalline. Monocrystalline panels have a greater conversion rate than polycrystalline panels. The wattage of solar panels can also differ.
Lighting fixture
LEDs are the primary source of light for modern solar streetlights, as they have a brighter light with a lesser power consumption. Energy consumption for an LED fixture is 50 percentage lower than the HPS equivalent that is typically used in street lighting.
LEDs don’t require an initial warm-up time, which allows them to work in conjunction with motion sensors. This may result in more savings in energy.
Rechargeable battery
The batteries store the energy generated by the solar panels and provide energy for the fixtures throughout the night. The lifespan of the battery is vital to the durability of the lightingand its capacity battery will determine the number of days of backup.
Gel deep cycle cells and lead acid batteries are both frequently used in solar-powered street lighting. Small lithium-ion batteries are also in a high demand due to their popularity.
Pole
Solar street lamps require sturdy poles, as they include numerous parts like batteries, fixtures, and panels that sit on top. Certain of the most up-to-date designs incorporate PV panels and the electronics integrated inside the pole. The other factor is wind resistance.
There are accessories available for poles like the battery box as well as a foundation cage.
Different types of solar street lights at bus stops
Each streetlight may come with itsown Photovoltaic Panel. It’s not connected to other streetlights. A collection of panels can be installed on a different site to be a central power source and provide power to a variety of streetlights.
The compact solar street light has gained popularity due to their small size. They come with the battery and all the necessary parts in a compact package.
Las Vegas in Nevada was the first city in the world to test the new EnGoPlanet Solar Street Lights that are paired with kinetic tiles which generates electricity when you step over the tiles.
