What is the difference between solar street lights and traditional street lights?

The development in photovoltaic technology has changed the way we look at how lights are lighted. It has improved the conversion efficiency of the solar panels greatly from a mere five percent in the 1940s to twenty percent recently. The solar panel market in the Middle East and many parts of the world is huge business.

Places like Dubai are changing the layout of the city and how it is powered. Due to the various advantages of solar street lights, traditional street lights are being replaced. So what are the reasons behind the change? Let’s look at the differences between the two.

Different Types of Solar Street Lights

Normally, there are just two types of solar powered street lights, namely, grid-tied and off-grid. It is important to know the difference between the two types, in order to understand the difference between solar street lights and traditional street lights. The grid-tied solar street lights are connected to an electricity company and will be using the electricity from the company for backup such as in the case there are days where there isn’t enough sunlight.

On the other hand, off-grid solar street lights aren’t connected to an electricity company and have their own small system. The solar energy is stored in the battery during the daytime and is used to light the street light at night. Usually, they would be able to sustain for up to three days when enough sunlight isn’t provided.

Therefore, if you live in a place where there are cloudy days, then, it would be better to choose a grid-tied solar street light.

Installation and Design of the Solar Street Lights

If you want the best results for either type of solar street lights, it would be vital to consider certain engineering parameters such as the panel size, local weather conditions, battery bank, panel size, lux level, light source watts, light posts distance, beam angle, autonomy and more.

Whereas, when comparing these parameters with traditional street lights, it can be observed that these parameters are not looked at.

LED Technology

The development of LED technology mostly benefits solar street lights as they have been made to provide better quality of light or an increased amount of lumens. They also have a longer lifespan. This means that the maintenance costs would be significantly less for solar street lights as compared to traditional street lights.

LED lights directly emit limit when means that the reflector cup wouldn’t be necessary to buy. The traditional street lights only emit diffused light which needs a reflector cup for better reflection of light. One can even apply a lens to the LED light.

Furthermore, LED lights normally provide you with the same amount of brightness as bulbs and require much less energy. This means that solar street lights require a lower amount of electricity to run.

Environmental Friendly

The main reason behind people switching to solar street lights is due to the fact that they are environmental friendly. For a much higher initial investment, the solar street lights have more benefits which make the investment worthwhile.
