What Are Solar Street Lights, and How Its Work

Solar street lights are powered primarily by solar panels that harness sunlight to produce electricity used to illuminate the streets. The light is then emitted as visible light and infrared waves; the former has a much shorter wavelength than white lights and does not cause as much visible skyglow at night time.

Solar street lights are also environmentally friendly because they don’t emit carbon emissions. For this reason, they are known for advantages and disadvantages of solar street lights often installed in urban areas where air quality is impaired from vehicle exhaust fumes.

Advantages of solar street lights:

  • Solar street lights provide a solution to the problem of a power blackout.

  • Solar street lights are environmentally friendly and don’t emit harmful gas like CO2.

  • Solar street lights are low cost; they don’t cost you anything; they will be paid off in 4-5 years just by generating power that saves you at the electric company.

  • Lighting your house or building using solar energy is more effective than using traditional lighting such as ordinary bulbs because sunlight is more powerful than incandescent light.

Disadvantages Of Solar Street Lights

Installation of solar street lights is expensive. The installation cost depends on the size of the panel and the type of electrical socket it uses. Smaller panels using smaller sockets cost less to install but will not last as long.

Solar street lights are prone to theft, especially during the night time when they are not illuminated, and are therefore invisible to thieves who can then vandalize them, destroy them or sell them on the black market.

Solar street lights do not produce sufficient illumination during cloudy times, thus making them ineffective during such situations.

Types of solar street lights:

Solar street lights are categorized according to the type of poles used for installing them. They include the following:

  1. Standard solar street lights.

These are solar street lights that are most commonly used. They are installed on the ground, supported by a pole, and can be installed both in residential and commercial areas.

  1. Ground-mounted solar street light poles.

These poles do not require a power supply because they use rechargeable batteries that can be charged using solar energy and regular electrical outlets. Upon charging, they can serve as emergency lights during power outages or blackouts, thus making them perfect for emergency evacuation routes and disaster relief areas.

  1. Wall mount solar electric light

These are solar street lights that are mounted on the wall. They have batteries connected to a controller that can be used to turn off or turn on each light individually. They are ideal for interior spaces such as garages and other locations requiring lighting.

  1. Inverted solar street lights


These work similarly to standard solar street lights, except they don’t have a panel attached to the ground. Instead, they use black aluminium posts with a wall socket below them which also requires a power supply and regular electrical outlets for charging.


This conclusion will analyze the advantages and disadvantages of solar street lights. Advantages of solar street lights over standard electric street lights and disadvantages of solar street lights. Solar street lights have many advantages compared to traditional electric street lights, especially regarding long-term cost-effectiveness and many disadvantages.
