As technology development. More and more people more popular use the all in one solar street light. Because it will include the led, and also have a camera. Using cameras to maintain the peaceful development of our society

3. Solar Flood Street Light

Floodlights are also widely used, such as basketball courts, football fields, tennis courts, badminton courts, and other sports places, which will use floodlights in a large numbers. Because he can help people exercise and improve their skills in the dark.

4. Solar CFL Street Light

The last type of solar street light is expensive but offers outstanding luminosity. CFL lights provide the best brightness at the lowest possible operational expenses.

Therefore, if you have a slightly higher budget and want to illuminate outdoor areas efficiently, you can opt for a solar CFL street light.

What are the features of solar street lights?

Solar street lights are becoming more and more popular is it has many advantages.

Advantages are as follows:

1. Charge Time

If the solar street light gets charged up quickly, it will generate more power even with sunlight. So, if the weather is dull and gloomy with only a few hours of the sun, it will be enough for the light to get charged.

Always choose a light having a quicker charging time, such as 6 to 8 hours.

2. Run Time

It will be easily capable of providing illumination for 10 to 12 hours, which is the type you must pick.

3. Lifespan

Be sure to choose a longer-life solar street light you do not have to invest anymore. Standard solar street lights with quality components may last for 10 to 20 years. However, the lifespan will depend upon the brand, occasional maintenance, and durability.

4. Brightness

Before buying any solar street light, you need to check its brightness measured in lumens. So, high lumens mean better lighting. You can buy one with 2700 or 6000 lumens, depending upon the area you want to illuminate.

5. Lighting Range

The lighting range of a street light will tell you the area it can light up. You have to consider where you want to position the light, such as a street, public park, or parking lot.

So, an alighting range of 400 to 800 square feet will be great, but you can also go for 1500 square feet if needed.

6. Design

You must always buy a light that is well designed and sturdy. So it is light and easy to move or install. The design must also consist of high-quality components for proper functioning.

You can also look for lights having solar panels with a checkerboard design for better sunlight absorption.

7. Durability

You need to verify the durability of a product before buying. Try to get lights with an aluminum or steel casing, which also must be temperature-resistant. In addition, look for will not leak corrosion-resistant batteries and improve the durability of the lights.

8. Weather-proof

Along with durable materials, street lights also must be weather-resistant. Check for the lamp rating. It is IP67 or IP68 that will protect it from rain, snow, or even tornados!

Lights made of ABS plastic are good, but a solid metal construction is always better.

10. Motion Sensor

These components are significant for energy conservation. As they increase or decrease the LED’s brightness according to nearby movement, you save a lot of energy.

11. Ease of Installation

You can easily set up most standard solar street lights because they do not have complicated electrical components. To ensure convenient installation, check if the product comes with an instruction manual, a set of screws, and a solid mounting pole.

In addition, you can also ask the retailer if they offer installation assistance.

12. Remote Control

The remote control can control the function of the street light well, even from a distance. The remote control gives you more control over the lamp and the flexibility to modify it.

As all modern remotes come with a good range, look for one covering an area of 26 to 40 feet.

13. Warranty

It is a wise decision to buy one with a good warranty.

Also, check for after-sales service and full refunds for grabbing a better deal!

14. Battery Life

The battery is the essential equipment for a solar street lamp. Solar street light major uses acid batteries, gel batteries, ternary lithium batteries, and lithium iron phosphate batteries.

Each battery has its advantages. Let us share the characteristics of these four batteries.

1. Lead-acid battery: the electrode plate of the lead-acid battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are voltage stability and low price. The disadvantage is that the specific energy is low, so the volume is relatively large, the service life is short, about 300-500 deep cycles and the daily maintenance is frequent. At present, the solar street lamp industry is still widely used.

2. Colloidal battery: It is an upgraded maintenance-free version of a lead-acid battery. Substitute for sulfuric acid electrolytes with colloidal electrolytes. It is superior to ordinary batteries in safety, energy storage, discharge performance, and service life. Some prices are even higher than ternary lithium batteries. In the temperature range of – 40 ℃ – 65 ℃, it is also used, especially with good low-temperature performance. It is suitable for Northern alpine areas. It has good seismic performance and can be used safely in various harsh environments. The service life is about twice that of ordinary lead-acid batteries.

3. Ternary lithium battery: high specific energy, small volume, fast charging, and high price. The deep cycle times of a ternary lithium battery are about 500-800 times, the service life is about one time longer than that of a lead-acid battery, and the temperature range is – 15 ℃ – 45 ℃. But the disadvantage is that it is not very stable. The ternary lithium battery of unqualified manufacturers may explode or catch fire when overcharged.

4. Lithium iron phosphate battery: high specific energy, small volume, fast charging, long service life, and good stability. Of course, the price is also the highest. The deep-cycle charging is about 1500-2000 times, with long service life, generally up to 8-10 years. Strong stability, a wide temperature range, can be used at -40℃-70℃.

Therefore, the application scope of street lamps is becoming wider and wider, perhaps more than the five items I listed. If you want to know more, please visit our website www.enetcl.com

How To Create a Better Solar Street Light Specification

Specification packages are typically completed by a company working with an architect or engineer to provide data about their product for a bid. These specifications are generally completed to ensure that a customer's needs are met and that everything will work well together. Street lighting is one of those areas where specifications need to be worked on with care to ensure that everything works well together and provides added benefits and safety. Let's look at what it takes to create a better solar street light specification.

 

What is a bad solar street light specification?

Before we get started looking at creating a better solar street light specification, let's take a quick look at an inadequate specification I recently saw on a recently released bid. There is much to be learned when comparing the two.

 

Solar Lighting Specification

Purchase and delivery of 10 solar street light systems with the following salient characteristics:

  • Solar panel
  • Sealed lead acid battery
  • Solid state system controller that regulates batteries and has a low voltage disconnect
  • Light fixture with LED lamp that produces good street lighting
  • Light fixture mounting bracket
  • The entire solar lighting system mounted on a pole

 

The primary reason this specification is so bad is that it is too vague. This type of bid release leaves the specification open to a host of different interpretations. The lack of specifics will lead to purchasing cheap solar street lighting systems that offer poor performance, reliability, and ROI. This, quite frankly, gives the entire industry a bad rap.

 

Creating a Better Solar Street Light Specification

The only way to avoid the above situation is to create a detailed specification that establishes precise solar street lighting system design and performance parameters, including:

Solar Power System

The solar power system should list the number of solar modules used in an array. This can be one or two in most cases, but there are sometimes when more is used. The solar section should also list if single / monocrystal or multiple / polycrystal solar panels are used.

 

The solar section should also list the total solar array wattage. This is many times confused for the fixture wattage.

 

Finally, the solar section should list how the solar is to mount to a pole, wall, or roof. It should also detail how the solar is mounted to the pole, either using a tenon top or a side of pole mount option and what type of bracket is expected.

 

Solar Light Fixture

The solar light fixture section should list the type of fixture and include any model or part numbers to distinguish between various options. Many fixtures have different options and salient characteristics, including:

  • Lumen per Watt provided by the fixture
  • Type of lamping
  • Light distribution pattern
  • Light level requirements such as foot candles
  • B/U/G rating and Dark Sky requirements

 

Also included in this section is what type of mounting the fixture should be used and at what height the fixture should mount. This will help with the next section.

 

Light Level Requirements

The light level requirements state precisely how much illumination that is on the project. The light level requirements should include information such as:

  • Specify area to be illuminated (ex. 2 lane street, each lane 12' wide with no median, light pole set back 5' from the edge of the road)
  • Light level requirements—the more detail, the better (ex. lighting on the street must be .3 foot candle average with lighting uniformity rations under 10:1)
    • Note: Never specify light levels according to 'equivalency' (i.e., LED fixture equivalent to 150 Watt metal halide) –as this spec type lends itself to many different interpretations! Such is not the case with foot candle specification, as a foot candle is a quantifiable measurement of light 

One of the worst things we see in specifications is only getting one piece of the puzzle when looking at the lighting portion of the specification.

 

System Controls

The system controller is the brain of the whole operation. The controller allows the batteries to charge correctly and not overcharge during the day. Depending on its programming, the charger also tells the lights when to turn on and off.

 

A detailed description of nightly system operation is critically important to ensure the solar lighting system meets needs since, with adaptive lighting being installed on most systems, dusk to dawn is not always enough information.

 

Understanding key requirements are essential when creating a solar street light specification, specifically what is the operation of the lights. For example, must the lights be on at full output from dusk to dawn, maintaining the light output all night? Or are the lights allowed to reduce the intensity or even shut off after a set timeframe.

 

If the lights are allowed to reduce or shut off, do you need them to be at full output again before dawn? If so, how long before dawn is this preferred. Remember that all light controls are set for the worst-case scenario, so dusk to dawn may be 14 hours in your location in the winter, but in the summer, you only run them 8 hours. So split time of 8 hours would look like this: on for 7 hours after dusk, shut off, on again 1 hour before dawn.

 

Battery Assembly

The battery is what holds power generated by the solar power assembly during the day for the fixture to use at night. Different battery choices are used for different types of installation. For example, Lithium isn't proven well in climates that get too hot or too cold. GEL or lead acid batteries each have their own set of pros and cons.

 

Make sure to list the salient features of the battery requirements, such as the type of battery, the storage size of battery assembly in Amps, the autonomy of the battery backup to ensure year-round performance, etc. Minimum backup for a GEL or lead acid system needs to be 5 days, whereas we are seeing Lithium able to carry a 3-day backup and still be very reliable.

 

The last section to provide for the battery information is the salient characteristics of the battery box and battery box mount, such as NEMA rating, construction materials, etc.

 

Solar Light Pole

The type of pole is critical to a system specification. The pole needs to be able to handle the weight and EPA of the solar power assembly with the wind conditions of the installation location. Other specifications include the material, such as aluminum, steel, concrete, or fiberglass. The type of pole, direct burial or anchor base, and whether you need a breakaway or auger base are good to have listed. Finally, what is the pole's finish requirement? Whether powder coated to match the rest of the system or everything is just raw aluminum and steel can completely change the price point and submittals.

 

With these design and performance parameters incorporated and woven into the specification, there is no question that the buyer will ultimately get high-quality solar power street lighting systems at the best possible price. It also means that the customer will receive the system that meets their specification and won't leave them in the dark.
