When you install a traditional commercial light, you don't often need to be worried about whether it will be 'bright' enough or will work continuously because there is an expectation that it will operate as specified. You dig the trench, lay the cable, connect to the public utility, and bam-you has the lighting.
Qianyun supply professional and honest service.
However, a properly sized modern commercial outdoor solar lighting system is a fantastic option if you want to avoid expensive and time-consuming trenching options, and you'd rather not pay any ongoing electricity costs. While solar commercial lights can achieve the same lighting results as traditional lights, there are some specific things you need to evaluate to make sure you get the right results.
Avoid overspending by making sure the lighting system uses the right-sized components for your project's requirements rather than using an unnecessary pricey system to make up for bad design.
Avoid battery changes or automatic shut-offs by installing a system that will be able to meet your long-term lighting needs rather than one that causes the lights to dim, causes the battery to fail too soon, or turns the lights off entirely.
Where exactly is the project located?
Try to get precise street addresses and site descriptions whenever feasible. Why? This enables the manufacturer's designers to take solar insolation information into their system design. Different areas receive different amounts of sunlight each day. For example, a solar light specified for sunny, southern California would be smaller and therefore wouldn't be able to generate enough power to provide continuous light for New York City. And a solar light specified for New York City would be unnecessarily large for California.
Knowing the project location allows the manufacturers to build and specify their systems for your exact location and to avoid proposing a system that's too small or too large for your area.
Additionally, a street address enables the evaluation of potential shading risks, such as trees, structures, or other impediments that could shade the solar panel and reduce the efficiency of your system.
What kind of area are you trying to illuminate? Is it street lighting or area lighting? Knowing the basic type of street vs. pathway will change the lighting output requirement.
Why? The application may have an impact on the necessary light levels, pole height, and pole spacing. For instance, a street probably needs more light than a park or trail. Here are some possible applications:
Urban Roads
Residential street
Pathway & park
Recreational Reserve
Parking lots
Perimeter & Security entryway
General Public Area
What is the length of the street/pathway or the size of the general area (for a parking lot, etc.)?
How much area are you trying to illuminate?
Why? The size or length of the area will affect the number of lighting systems required, and the uniformity of the light hitting the ground, which all factor into the overall project cost.

Will your project require pre-existing poles or new poles?
Is there a specified pole height request? What's kinds of poles are required? like a single-arm or double-arm pole or without an arm pole.
Why?
The height of the pole may affect the number of lighting systems required for the project.
The type of light pole may affect the cost of installation.
Height of typical streetlights: 25 to 30 feet
Height of typical walkway lights: 12 to 20 feet
Typical light pole types:
adjustable cone-shaped poles, Conical poles, octagonal poles, straight pole
If there are frequent typhoons or hurricanes in the area, your customers will also have a certain demand for the wind resistance rating of the light pole.
After we know the Road Width, Road lanes, and Road length, we are going to consider which installation type is suitable for our project. There is some common installation type to u check:
Installation pole height and Installation distance ( If it is a new installation project, this condition can be adjusted in the design process'
We will choose whether to lay the lights on one side, on both sides, or to cross the lights, depending on the road conditions.
Is there a state/municipal standard for light levels for the project, what are they? What light levels need to be met on the ground (measured by foot candles or lux)? What uniformity requirements are there if known?
Why? Different applications will require different light levels, which plays a large role in determining the overall project cost.
Manufacturers can make a lighting design by Dailux Simulation for your project to make sure the lux and uniformity match your lighting requirement.
How long does the light need to be on each night, 6hrs or 12hrs even 14hrs? When the light is on, do the light levels need to be met throughout the night at full brightness or just at certain times with dimming mode? If you're unsure, a good manufacturer should be able to help.
Why? The operating profile is a key aspect of a solar lighting project. Manufacturers will 'tune' their systems differently for power management, based on these profiles.
1. Dusk to dawn (all-night operation): the light will run at the same light output level all night.
2. Dim in off-peak hours: for example, the light will run at the required light output level for 5 hours after dusk, then dim to 30% of the required light level. 2 hours before dawn, the light levels will return to 100% until sunrise.
3. Off or dimmed at an exact time: for example, the light will run at the required light output level until 11 p.m., then will turn off.
Remember the lighting profile can be customized according to customer request
An important note on dark-sky friendly lighting. Planned dimming operations during periods of low activity (midnight) can reduce overall system costs and make projects more dark-sky friendly.
We all know that solar lighting systems depend on sunlight to work, and if they happen to have continuous rainy days for 5-7 days, or even longer than that, the solar lights may face the risk of going out. This is why we need to consider the local lighting weather conditions when designing solar lamps to configure the right battery size to meet the normal operation of rainy days.
For example, in the UAE, where it rains less than 7 days a year, we only need to consider 1 rainy day battery backup, but in Europe, where it rains continuously, we need to consider 5 rainy day backups. The vast majority of the world considers 3 rainy days.
For more information, please visit all in one solar street light.
We calculate the size of the battery configuration based on the nightly operating mode and the rainy day backup time, and the size of the battery is a large part of the cost of the whole system. Longer rainy-day backups mean higher battery configurations and more expensive costs.
What color of light is required'warmer (K) or cooler (K)?
Why? Color temperature affects the fixture power output and can factor into the project cost. While the light color temperature may be more of a preference than a requirement, cities are leaning more towards lights with warmer color temperatures as they seem to be better for our health and the environment.
Let's review these ten questions to ask about your commercial solar lighting project. To gather the relevant project specifics, ask about the:
1. Project Location
2. Project Application
3. Project Dimensions
4. Project Type
5. Pole Height and Type
6. Installation Type
7. Required Light Levels and Uniformity
8. Operating Profile
9. Back up rainy days
10. Color Temperature
Asking these questions can ensure you're specified a solar light that will meet your project requirements over the long term at no extra cost. You can also be confident that your lighting system won't die prematurely or become unnecessarily large and expensive.
1. Do you have any specific aesthetic concerns?
2. Do you already have a budget in mind?
3. Who else is involved in your project, and what role will they play?
Planning out your public lighting project early can save you time and money.
All solar lights require four basic components: solar panel, charge controller, battery and led light source. Solar panels generate electricity in the sun. The battery stores the electricity generated by the solar panel. The LED light source provides the brightness. And the charge controller ensures that all three other components can work together safely.
If you read the first question, you will know that solar lights need batteries. If there are no batteries as the energy storage component in a solar lighting device, then without sunlight, the solar light will have no energy.
Here, we will answer you in two parts. In the first part, if there is not enough sunlight throughout the day, the solar light will not work for too long during the lifetime of the solar light. The second part, the life span of solar light components. Different quality of battery is 1-5 years. Solar panels of different quality have a life span of 10-25 years. Different quality of solar charge controller is 3-5 years. Currently, most solar lights on the market have a life span of only 1-2 years due to battery life.
Solar lights need sunlight in order to get enough energy. Therefore, designed for outdoor use is waterproof.
There are
a: 100% solar energy, no need to pay electricity bill. Maintenance fee is far cheaper than led with electricity.
b: No wiring required. Customers do not need to trench for solar lights. This can save the cost of electrical workers and wire costs.
c: Solar lights are easy to implement intelligent control to save energy.
d: The luminous efficiency of solar lights is 10% higher than electronic led lights. Therefore, the solar lights can reduce the LED power with the same brightness.
When the solar light is not working, you need to check 6 parts. Battery, controller, LED, solar panel, switch and wire connection. The most easily damaged parts are the battery, the switch, the controller and the wire connection. Therefore, the first step is to check all wire connections for looseness. Then replace the battery, switch and controller with new ones to check which one is bad.
If it is not very dark on a cloudy day, the solar lighting system can still generate electricity at very low power. If it is very dark, the solar lighting system will not work at all. However, there are technical ways to ensure that the solar lights work 100% of the time on cloudy days. We can place the solar lights on the grid to ensure that the solar lights can be powered through the grid when the battery power is turned off.
On the electrical side, solar lights are much safer than electrical lights. This is because solar lights are low DC voltage, while electric lights are high voltage AC power.
However, some poor quality solar lights contain poor quality lithium batteries that carry the risk of spontaneous combustion.
The led power, battery capacity and solar panel power determine the lighting time of the solar lights at night. Sold on Amazon for $20 to $60 solar lights can last 1-3 hours of full brightness lighting time. With motion dimming and automatic time dimming, the solar lights have enough lighting time for daily house use. For solar street lights with larger battery capacity and solar panel power, they can last all night lighting for 3-4 cloudy days.
Reason 1: Loose wire connection. Reason 2: The controller is broken.
Artificial light can more or less charge the solar light. Full spectrum light is better than narrow spectrum. Therefore, traditional light bulbs can charge solar lights better than LED bulbs.
Solar panels produce electricity. And it is the batteries that store the electricity. In this way, solar cells can work at night using the electricity in the batteries.
For all portable solar lights, you can put the solar lights in a place where there is enough sunlight. and move them into the house at night. Please note that you must make sure that the solar light has enough sunlight to charge the battery during the day.
First of all, solar cells are 100% rechargeable. Just make sure that the voltage and currency specifications of the batteries match those of a conventional charger and there will be no problem.
