Illuminate streets and roadways by using the power of the sun with our solar street lights. Easy installation and independently powered, solar street lighting save you time and money. With LED solar street lights, you can realize even more savings when you use energy-efficient and long-lasting LED light fixtures. LED Lighting Supply is your solar-powered street light supplier's resource for solar lighting.

How Do Solar-powered Streetlights Work?

Using Photovoltaic (PV) panels, commercial solar streetlights get their energy from sunlight during the day. These panels are mounted onto the lighting structure (such as a pole), or directly on the fixture. They draw electrons from the sun photons that hit them. The electrons are then sent to DC power and saved in a rechargeable battery.

When the sun goes down, sensors are used to change the flow of energy from the battery to the source of light. The light source is turned on automatically. After the sun rises, the light source is turned off and the process of charging the battery begins again.

What are the Advantages of Solar-powered Streetlights?

Street solar lights have several advantages over traditional street lighting:

  • You can eliminate monthly energy costs because these lights are not connected to a utility main. They are self-sufficient.
  • Installation costs are vastly reduced because there is no need for trenching to run wires as traditional street lighting would require.
  • Outdoor street solar lights are off the grid and not dependent on the local utilities for power. That means that streets and roadways will continue to be illuminated in the event of a power outage.
  • You can take advantage of government rebates and tax incentives that are offered in your area to save even more money on upfront costs.

What are the Disadvantages of Solar-powered Streetlights?

While solar-powered streetlights are a great lighting choice, they have some disadvantages compared to conventional streetlights:

  • They require a higher up-front cost compared to standard lighting.
  • You’ll need to occasionally clean the PV panels due to dust or moisture and snow accumulating on them. There is an elevated risk of reduced/stopped energy production if they are not kept clear.
  • Their rechargeable batteries will need to be replaced a few times during their lifetimes. This is especially true if you’re using LED fixtures because the lights will last much longer than other types of luminaires. You’ll want to account for this when considering maintenance costs.

How Much Do Solar-powered Streetlights Cost?

There are two parts to the cost of these lights: the lighting components and the installation. Compared to traditional street lighting, solar-powered LED roadway lighting components are more expensive, but the installation costs are much cheaper. On average, solar-powered street lights we carry will cost between $500 and $1000 each.

How Long Do Solar-Powered Streetlights / Solar-Powered Parking Lot Lights Last?

There are three points to consider when discussing the lifespan of solar street lighting or municipal solar street lights:

  1. The lifespan of the light fixture. The lifespan of LED outdoor solar street lights will usually be in the range of 50,000 to 100,000 hours of use.
  2. The lifespan of the rechargeable battery. They will not last as long as the LED light that they are powering, so they will need to be replaced a few times before the light source reaches the end of its usefulness. On average, expect the batteries to last around four years.
  3. The quality of the product. There are many options available for solar streetlights. Choosing a reputable solar street light manufacturer will ensure better craftsmanship and is a tell tale of what you can expect during after purchase support.

 

How Bright are Solar Power Street Lights?

It depends on the light source that you use. It is recommended that commercial-grade LED lights are used due to their high-lumen output. It is important for the light to be bright enough for drivers to safely see the road but without unnecessary glare. Solar LED streetlights not only provide the brightest option, but they also emit the highest quality of light.

The brightest Solar Powered Street Light we offer is 100 Watts producing 20000 lumens

Another thing that you’ll need to consider is the height that the fixtures are mounted. A higher mounting height will require a brighter luminaire so that light effectively reaches the road and is evenly distributed.

Can Solar-powered Streetlights Be Used in All Climates?

Yes, they can but it’s important to understand that they may require additional maintenance in harsh climates to keep them working properly. Dust, rain, and snow can accumulate on horizontally mounted PV panels, and when this happens, the panels will need to be kept clear so that they can function reliably. And if you live in a cloudy area, solar-powered lighting may not be the best option.

How Much Sunlight Do Solar Streetlights Need?

Commercial solar LED street lights charge quicker with direct sunlight than with partial or full shade. As a rule of thumb, 6 to 8 hours of direct sunlight will fully charge the battery and this should last for 5 to 7 days.

How Do Solar-powered Street Lights Compare to Traditional Street Lighting in Terms of Cost and Efficiency?

The PV panels and rechargeable batteries will add additional cost along with the LED light fixtures. The trade-off is that it’s offset by lesser installation costs than traditional LED lighting and zero utility charges. Otherwise, the efficiency of the light source itself will be the same.
