Solar street lamps are an elevated light source that is powered by solar cells.
The panels are integrated into the pole, or placed onto the structure.
The solar panels are used to recharge the battery that powers an LED or fluorescent lamp at evening.
Here are a few examples of
The solar panel’s voltage is utilized to detect light from outside and turn on or off most solar lights.
Solar streetlights run all night.
Certain solar streetlights can be used for longer than one night, provided there is a long period that the sun does not appear in the sky.
The earlier models had lamps that weren’t fluorescent, or LED. Solar lights in the regions that experience wind typically have flat-paneled solar panels. This helps them cope better with the elements.
Modern designs are based on wireless technology to manage batteries.
This technology lets street lights be operated as a whole, and each light can turn on and off the whole network.
Components
Solar street lighting is made up of four major components:
Solar panel
Solar panels are an important part of solar street lights,since they convert solar energy into electricity to power the lamps. Street lights that are solar powered are typically ma-de, and there are two kinds of panels: monocrystalline or polycrystalline. Monocrystalline panels are more efficient in conversion rate than poly-crystalline ones. Solar panels also vary in power.
Lighting fixture
LEDs are the major source of lighting in modern solar streetlights because they offer a higher brightness and lower energy consumption. The energy consumption of a LED light fixture is about half of the HPS counterpart, which is commonly used in street lighting.
They can be used with motion detectors because they do not require warm up. This may result in more energy savings.
Rechargeable battery
The batteries are used to store the power produced by solar panels. They also provide power to the fixtures during the night. The lifespan of the battery is important to the longevity of the lightand the capacity of the battery will determine how many backup days.
Solar street lighting is usually powered by lead acid and deep cycle gel cells. The compact lithium-ion batteries have an enormous demand because of their popularity.
Pole
Solar street lights need strong poles, as they often include components on top like fixtures, panels and batteries. In the most recent designs the electronic components and PV panels are integrated inside the pole. Another issue is wind resistance.
These poles can be enhanced with other accessories like the battery box or foundation cage.

Every street light could have itsown photovoltaic panel. This is separate from other street light sources. A collection of panels can be erected on a different site to function as the central power source to power many streetlights.
The compact solar street light has gained popularity because of their small size. They come with the battery and all the essential components in a compact form.
Las Vegas in Nevada was the first city in the world to test the new EnGoPlanet Solar Street Lights that are connected to kinetic tile that produces electricity when people are walking on the tiles.
