Top 3 factors to choose outdoor solar lights properly

Users or consumers often find there are lots of key factors in selecting outdoor solar lights,hence, we figure out top 3 factors here.

Top 3 Factors to Choose Outdoor Solar Lights

We all understand that we shall make a good quality product for our users across the world. No matter they are coming from Malaysia, Saudi, UAE, Sweden, Brazil, Australia, South Africa, Namibia, Uganda, or elsewhere, they will all be treated with a high standard quality product. Mostly, the solar-powered street lights are all in one type in the market. All in one is actually three in one type. Three means three major parts for solar street lights, i.e.  solar panel, LED light, and battery. Therefore, I am recommending use to take a look at these top 3 factors before buying solar-powered street lights. Let’s begin.

 

1 – EFFICIENT SOLAR PANEL FOR OUTDOOR SOLAR LIGHTS

It took around two decades for photovoltaics (PV) or solar PV to become a mainstream electricity source from small scale applications. Price in the past could only be accepted by users like military and aerospace who don’t really care about the cost too much. Now, the price has dropped to a level that is affordable to civil users.

Solar panel energy has been developed for many years. Technically speaking, the product is mature enough. Usually, the high-efficiency solar cell will come with an MPPT controller for stable performance. The controller also takes care of light absorption in summer and winter.

As regards to the efficiency, monocrystalline solar panels are higher efficiencies and sleeker aesthetics than polycrystalline solar panels. Doubtlessly, polycrystalline panels are sold at a lower price.

Both monocrystalline and polycrystalline solar panels serve the same function in the solar PV system: they capture energy from the sun and turn it into electricity. The technology is so powerful that it can even work and provide lighting under weak light conditions. This is especially helpful in wintertime for high latitude areas like Sweden and Canada. Our customer in Sweden is continuously buying solar-powered street lights from us which is a great honor to us. It is sure that we have installed a special component unit for Sweden market which need complementary power in winter.

As mentioned, the solar panel industry has been developed for so many years. The solar panel itself is guaranteed with at least 20 years lifespan in most cases.

 

2 – OPTIMIZED LED LIGHTING SYSTEM

LED-bulb-colorful-diode-light-technology-electricity
The top 3 factors for outdoor solar lights go number 2. LED chips are various and different chip vendors provide respective lighting solutions. Bridgelux, Cree, Lumileds, Nichia, OSRAM and Philips are common choices of solar lights factories who cherish their product quality and reputation.

For example, when we choose Bridgelux, we will take into consideration of LED power and lumen efficacy into consideration after comparison between brand and brand. Bridgelux has great performance regarding ESD protection. ESD protection devices (anti-static components) protect a circuit from Electrostatic discharge (ESD). The value of ESD for Bridgelux can be as high as 3000V. The product of the brand has high stability because it has a double electric shock structure and has 6 protective films on the surface. The factory is easier to operate in the downstream production process while the product yield is better controlled. At the same time, the light decay is less.

As a whole, other brands are also being picked for use when we produce a specific item since we need to consider the system output performance.

 

3 ENHANCED BATTERY UNIT EMPOWERS SYSTEM PERFORMANCE

Lithium-ion-Battery
The battery unit is outsourced from battery vendor. If an outdoor solar light manufacturer wants to use a low-cost component, then a lead-acid battery is possibly being used. The lead-acid battery has one of the lowest power-to-weight & power-to-volume battery designs in existence, making it big and heavy for the total amount of power it can put out.

In past years, quite many off-grid energy systems are equipped with lead-acid batteries. Now, most of them are defunct or replaced. People are turning to the solution of LiFePO4 lithium-ion battery.

LiFePo4 battery pack with 2000 times long life circles which is 3 times longer than Lead-Acid battery. When you browsing on the internet shopping site for outdoor solar lights, some vendors will indicate the warranty time of the product. Some warranties are so short that you will question yourself for what circumstance a customer will buy and question sellers for what kind of product they are selling at such a low price.

Moreover, please be aware of some suppliers who are using second-hand batteries taking down from electric vehicles.

Above the top 3 key factors are of fundamental importance as they are the main parts of outdoor solar lights.

We are carefully selecting our battery vendor and use the lithium battery product that can support a longer lifespan which is beneficial to both customers and us.

7 Types of Solar Energy Applications

Before most of us were born, solar energy applications had been widely used.  In fact, not just 7 types of them, but many of them have a profound impact to us.

 

The first spacecraft to use solar panels was the Vanguard 1 satellite in 1958. The artificial satellite has taken advantage of solar energy. Mostly, it is because of the influence of Dr. Hanz Ziegler. It is a significant sign of science and technology. Although later Apollo space shuttle did not carry solar panel to finish the mission, people nowadays would rather believe that Apollo had been landed on the moon with the help of the solar system.

 

Here let’s take a look at 7 types of solar energy applications that have great influence to our life.

solar-energy-solar-outdoor-lights-solar-powered-led-street-lights.

  1. Solar Home Lighting System

Are Low Voltage Solar Lights Safe Enough To Use?

Today, we take a look at Safe Low Voltage Solar Light to see how it affects our daily life.

STREET LIGHTING SYSTEM IS COMING TO A NEW AGE AS LOW VOLTAGE SOLAR STREET LIGHTS ARE BEING HIGHLY DEVELOPED AND INTEGRATED. THE IDEA OF USING SAFE LOW VOLTAGE SOLAR STREET LIGHT IS BEING ACCEPTED WIDELY.

 

  • STREET LIGHT POLE MAY HURT

From time to time, the flood will occur during the raining season in China or in other regions. The flood may cover street pole which causes electric leakage if the infrastructure is not being well established. It is extremely dangerous if electric leakage happens as few people may know it is happening unless someone is accidentally electrocuted himself/herself. Such a tragedy is not a single event. It is well known by people in other countries as it happened so many times.

Each life counts. Some people will think about the possibilities for us to do something that can stop such tragedies.  If it is caused by a technical issue, then we must have some way out technically.

If the flood is caused by drainage, then, the water drainage system shall be re-built.  Usually, the conduit drainage system is built underground in the city. The underground network is huge and wide. As the underground drainage system is determined by height of terrain very much, it is hard to optimize to an assumed goal.

 

To avoid the lethality of electric shock or other electrical injuries, it is crucial that we set up a road network that is safe for the people. It is doubtless that it takes time for the responsible municipal construction unit to make a decision for lamp pole up-gradation. Budge of construction may also be tangled for a long time even after an agreement to re-build is reached by relevant parties.

Is there any easy way out? It is quite a headache for people to find a way out using the brains and tactics to get things done.

  • SAFE SOLUTION FROM SOLAR STREET LIGHT

When we are talking about up-gradation, an idea of an off-grid street light network is coming out. Luxman suggests that solar-powered street light is one of the best choices as green energy supply is playing an important role in city life. Considering that solar-powered street light is run with low voltage current that is as low as 12V and it is safe for everyone. Furthermore, Solar street light does not depend on grip power that means it does not call for mass cabling cost. The total implementation cost is regarded as at a moderated level.

With solar street light installed, there is no need to consider electric leakage resistance or arc resistance which is inevitable to high voltage DC (direct current) powered street pole network. No death will result from accidents like an electric shock. Here we can see a comparison of low voltage using by a solar street light and high voltage using by old fashion street light.

Safe Low Voltage Solar Light VS Old Street Light

ItemVoltageRiskRecommendationSupplier
Solar Street Light12 VoltsVery LowYesLuxman
Old Street Light110V or up to 220VVery HighNo/

Obviously, stand-alone solar street light perform better if strong wind weather with heavy rain. Just imagine when flooding on the street has been kept for a certain time and pedestrians want to wait no more but take the risk to walk in the water. Solar street light can not hurt anybody even electric leakage occurs since 12V current is completely endurable to the human body. Besides, solar street light is designed to resist wind, water, and electric leakage. The basic designs guarantee the safe operation of the product itself and the safety of people around the street light pole.

  • REASONS TO CHOOSE LOW VOLTAGE SOLAR STREET LIGHT

  • (1) Suit for Geologically Unstable Area

As we all know, developed country like Japan is tortured by an earthquake due to the movement of the earth’s crust or tsunami, people there have to tackle the problem like flooding after an earthquake. They understand the importance of low voltage of solar-powered LED light. They appreciate the safeness of solar LED light.

  • (2) Protect People from Unexpected or Inevitable Harm

People will be definitely going to spend some time outdoors because of working or simply playing. Kids can only grow up healthily with the touch of the outer world. A low voltage lighting system ensures peoples are safe from high voltage electric shocks, in case that they touch something mistakenly or are forced to touch dangerous objects. As a result, the consequences of an accident can be miserable and heartbroken, if the lighting system is a 120-plus-volt system.

  • (3) Safety Is the Top Priority

The safety of people means a lot. The safety of people is the base of other activities. Luxman believes that it is easy to learn that low voltage is safer compared to the high voltage power supply. The advantage of low voltage operation of solar street LED light is gradually recognized and accepted by people around the world. Luxman believes that other countries cherish the life of people as well.

These are probably the reasons why low voltage street lighting is recommended for residential properties and public areas. Shenzhen Luxman Light Co., Ltd has been providing solar street light to meet the realistic needs of their daily life. We cherish people’s life by providing quality & safe products, i.e. low voltage solar street light.

We are here to serve you with our professionalism. Together, we can build a better world.

LUXMAN - solar street lamp

How to choose batteries for your solar street lamp project?

Outdoor Solar street lamp battery equipment has a built-in type, Pole mount type, and buried type.

solar street light battery

                             Built-in type                            Buried type                           Pole mount type

Built-in is the lithium battery pack integrated together into the lamp body; If an external pole mount type is selected, it is better to install the equipment on the solar street lamp with a height of 6 meters, and there should be no climbing objects beside the solar-powered streetlamp, also pay attention to anti-theft. If to choose the buried type, it is best to pay attention to anti-theft, waterproof, pouring cement ground to density, and replaceability.

The battery is a very key component of the solar-powered street lights system, and also a major component of the solar-powered street lights system cost. At present, solar street lamps mainly use Gel batteries and lithium batteries.

First, explain the concept of both:

Gel batteries belong to a development classification of lead-acid batteries. The method is to add a gelling agent in sulfuric acid to make the electro liquid of sulfuric acid become colloidal. Electrohydraulic colloidal batteries are commonly referred to as colloidal batteries.

 

The lithium battery is a kind of lithium metal or lithium alloy as a negative material, using a non-aqueous electrolyte solution, compared to a commonly used colloidal battery, the lithium battery is more environmentally friendly, lightweight and longer life, of course, the price of lithium battery will be slightly higher

solar street light battery in china

The lithium battery is a kind of lithium metal or lithium alloy as a negative material, using a non-aqueous electrolyte solution, compared to a commonly used colloidal battery, the lithium battery is more environmentally friendly, lightweight and longer life, of course, the price of lithium battery will be slightly higher.

 

Lithium battery

Gel battery, lithium battery have their own characteristics, but in recent years lithium battery solar street lamp systems develop much better, what are their advantages? Let’s briefly compare the differences between the two:

 

  1. Solar-powered street lights  power supply method:

Lithium battery 12V 120AH storage power, higher than the colloidal battery 12V 120AH storage power, lithium battery can be full of release, lithium battery cycle high life is 3~5 times than the colloidal battery.

 

  1. The maintenance cost of solar-powered street lights

Gel battery service life in 2-3 years, lithium battery service life in 5~8 years, to ensure almost no maintenance costs.

 

  1. Are solar-powered street lights environmentally friendly?

Gel battery production pollution is serious, can not be recycled and used, heavy metal pollution is serious, non-environmentally friendly batteries;

The lithium battery is an environmentally friendly battery, lithium belongs to the light element, is harmless to the human body, iron in the soil is ubiquitous.

 

  1. The material cost of solar led street lights:

Gel battery production technology is difficult, high cost; Lithium-ion batteries are environmentally friendly and cost slightly more than colloidal batteries. But overall accounting down, the lithium battery solar street lamp cost is more cost-effective.

  1. The installation cost of solar led street lights:

Gel battery is relatively bulky, generally need to be buried, must do waterproof anti-theft work, installation labor cost is high, late maintenance cost is also very high; Lithium battery is lightweight, high energy density, generally integrated in the inside of the lamp body or under the solar panel, the battery installation does not need labor costs, the maintenance is simple and convenient.

solar street light design

By comparison, we can see why more and more solar street lamps look less bulky than before, due to the use of lithium batteries. The lithium battery is used in solar street lamp systems, and has the advantages that ordinary Gel solar street lamp battery does not have:

I. The charging and discharging system of lithium batteries generally adopts the integrated structure of lithium battery and controller, which is an energy storage battery system with no pollution.

II. According to the user’s demand, the remaining capacity, operation days and nights, weather conditions, and other factors can be intelligently optimized and calculated, and the power level can be reasonably distributed. The functions of light control, time control, and memory storage, to ensure the intelligent setting of the solar street lamp system.

III,  Lithium battery due to dry battery nature, more stable than Gel battery, safer.

IV,  Lithium battery weight is light, the same capacity specification weight is about 1/6-1/5 of the lead-acid Gel battery;

V,  The environmental adaptability of lithium battery is stronger, the use of a wide temperature range can be used in the -20℃- 60℃ environment, after technical treatment, even can be used in the -45℃ environment, which also provides conditions for the promotion of solar street lamps in cold areas.

solar led street light

Solar LED Street Lights Application Analysis

When Greta Thunberg, a Swedish environmental teenager, chose to sail the Atlantic for two weeks before arriving in New York for the United Nations’ youth climate summit, Luxmanlight employees were actively promoting the use of Integrated Solar LED Street Lights around the world. Different views on the same event just represent our different ideas on environmental protection.

The all in one solar LED street light is the product of modern science and technology development. It directly uses solar energy for power supply, environment-friendly, and energy-saving. With the characteristics of once investment and long-term return, traditional street lamps and an LED street lamp is gradually replaced. The solar street light with an automatic lighting system is generally used for street lighting of urban and rural roads. The intelligent street lighting system can realize the intelligent monitoring and management of street lights and reduce the operation and maintenance cost of the system. Thanks to its stable performance, easy management and no need for electricity connection, it is becoming more and more popular. Solar LED street lamps are used in parks, communities, squares, and parking lots from remote rural areas to cities. According to our customer’s experience, now we summarize the main installation locations of solar street lamps.

 

Application location of solar LED street lamps

  1. Rural road lighting

The rural natural environment is harsher, not suitable for laying cable. Solar lamp installation is simple, long service life. Moreover, rural roads are narrow and small, and the requirements for LED light sources are not high, which is suitable for installing stand-alone solar LED street lights.

solar road lightsolar street light

  1. Monitoring and lighting of farms, barns, doorways, and courtyards

House installation of solar street lights not only very convenient night lighting, but also can be equipped with a camera monitoring function. In the meantime, installation is simple, still can save a lot of electricity bills. Current standard configuration with light control, will according to illumination (brightness) automatically turn on-off the light, auto-off in the day, auto-on light at night, very simple and convenient.

  1. Homestay, resort, and hotel outdoor lighting

Lighting safety, environmental protection, and energy-saving are the pursuit of the concept of homestay and hotel, so the solar street lamp is the right choice.

  1. Mining area, remote power shortage place lighting

Mining areas are usually quite remote, so the cost of installing street lamps by cable is very high. Therefore, it is appropriate to choose a solar street lamp. Luxman solar LED street light works 12 hours a night and can support 5-7 rainy days. The road may still be rough, but it is no longer dark and safe to travel.

  1. Island lighting

There is no doubt that islands are short of electricity, especially the remote, smaller islands, which are 100% short of electricity. Diesel power doesn’t work 24/7 and there are always dark hours, but solar lighting will keep your nights dark no matter how windy or rainy.

LUXMAN - solar street light 1LUXMAN - solar remote area light

  1. Monitoring and lighting of the home town villa

Many young people like to live in the city, where the house is only for old people and children or no one lives. Therefore, a kind of solar street light with a camera that can be illuminated and monitored is very suitable for use. like Luxman S3C Series solar street light with a camera for residential areas.

  1. The lighting of urban roads and secondary trunk road

Energy-saving and emission reduction can be achieved not only by using AC Powered LED lighting, but also by using more advanced solar-powered street lighting without electricity bill, which can be invested once and be effective for a long time.

  1. Square, parking lot, playground lighting

There’s a lot of traffic in public places, but it’s usually only in the early hours of the night. The intelligent solar street lamp can do induction mode(PIR), time control mode, and can also do induction + time control hybrid mode, so it can meet the lighting use in public places.

  1. Schools, hospitals and museums outdoor lighting

Environmental protection is everyone’s business. The low-carbon concept must be promoted from schools to hospitals, exhibitions, museums, and another outdoor lighting. Integrated solar street lamps not only meet the lighting needs but also have a prominent environmental protection demonstration effect.

solar garage lightssolar campus lighting

  1. Park and green space lighting

In general, the lighting of parks and green Spaces does not require high illumination on the ground (compared with outdoor stadium lighting). Intelligent solar street lamps are the best choice for lighting in these public areas.

  1. Community road lighting

The lighting of community roads and garden roads in the community has changed from traditional lamps to LED lamps and then to solar street lamps, which is the trend of the times.

  1. Industrial zone, science, and technology park, road lighting

In industrial areas, science and technology parks or innovation incubators park, no matter traditional lighting or LED lighting which used for public electricity, it is not as cost-effective as solar street lamps after cost accounting.

13.Outdoor camping lighting

The installation of LED solar street lamps in some of the best places for camping not only solves the main problem of campers but also ensures their safety to some extent.

In the future, more than 70% of roads and lighting are expected to use solar street lamps, compared with less than 5% today. At present, the price of a solar street lamp is mainly set according to the level of parameter configuration, and the service life is closely related to the configuration. The solar street light manufacturer offers a five-year warranty, which is favored by many customers.

solar parking lot lights

5 Benefits Of Solar Parking Lot Lights – Luxman Light

Usually, there is a lot of open space in the outdoor parking lot. If the grid electric parking lights are installed, they need to be connected to the power grid and laid wires. However, the Solar Parking Lot Lights independent design and working alone, do not have these problems, so the solar parking lights have been used more and more. Below is a brief analysis of the advantages of solar parking lights over traditional Grid LED street lights.

 

Installation anywhere

Since the Solar Parking Lot Lights does not need to be connected to the grid, there is a site limit for installation. It can be installed in remote islands, remote camps, rural roads and so on. In addition to these remote areas, solar street lamps can also be installed in natural disaster-prone areas, because these areas require higher safety performance, such as the Japanese government stipulated that no AC lighting can be installed on the riverside, so DC solar street lamps are a good choice.

No electricity wiring

Solar car park lighting saves time and money by not trenching to lay down traditional electric wiring. Instead, installing an anchor base pole on a concrete foundation and installing the solar power assembly and light fixture on the top of the pole gives you light in less than a day, not weeks of digging and pouring new concrete.

NO electricity bill

Because the solar street lamp is 100% powered by the sun, it is a 100% off-grid lighting system. It will not generate any electricity charges, and will not cause any pollution to nature. It is also a 100% green energy lighting system, so the solar street lamp has been well applied in some countries and regions with high electricity charges.

 Maintenance-free

With solar battery technology improvement and updates, which makes solar street light quality is very stable. Moreover, according to our installation record and project engineering data, the failure rate is around 0.1%, so the maintenance cost is very low for the distributors or Solar lighting users.

Smart Control

End users can control the lighting modes from a remote control or mobile phone APP, They can switch ON/OFF, adjust brightness and choose lighting mode according to the weather condition and using environment. Each component working status and failure detection can be detected and monitored mobile APP.

HOW TO MAINTAIN ALL IN ONE SOLAR STREET LIGHTS

SOLAR POWERED STREET LIGHTS ROI VS GRID. -LUXMAN

 

screws

Why does solar street lamps design with internal hexagonal screws?

You may find that almost all solar street lamps are designed with inner hexagonal screws. Why are solar street lamp engineers so keen on using inner hexagonal screws for solar street lamps?

You will find that 99% of the assembled furniture bought online is hexagonal. The screw head of the inner hexagon screw is round outside and concave in the middle. Such a structure has obvious advantages.

Solar-Street-Light-Screws

  1. Load bearing is greater.

It has six surfaces to bear the stress from a screwdriver, which is more capable of holding the screw than the one-sided screw and the cross-shaped screw with only two faces.

Note: The material of inner hexagonal bolt is generally made of stainless steel, carbon steel, and alloy steel, which are basically the same as other types of screws. The higher the performance grade, the greater the strength will do. When selecting the screw, the screw of suitable performance grade must be selected strictly according to the user requirements. The grade is different, and the price is also different.

    2. It can be buried when treatment.

That is to say, the whole nut sinks into the inner part of the workpiece, which can keep the surface of the workpiece flat and beautiful.

    3. Easy to installation.

Compared with the outer hexagon screw, the inner hexagon is suitable for more assembling occasions, especially narrow ones. Therefore, it is very convenient for assembling, repairing and maintenance.

   4. Not easy to disassemble

Our common tools are movable wrenches, screwdrivers, and solid wrenches, while the removal of hexagonal bolts must use a special wrench, so it is not easy to disassemble, which is also an advantage.

Of course, if you may think you can design many kinds of weird structures, but the problem is that the special wrench is much more complicated to be manufactured.

Internal-Hexagonal-Screw-Driver

As for this wrench issue, some people feedback that since the inner hexagonal bolt has the advantage of strength and is designed as a sinking hole, it is difficult to screw out in case of slippage, while the outer hexagonal bolt need common tools only to do so, why not design it as the following shape?

As you know, the outer hexagonal screw head is exposed. The wrench needs a certain space to screw out it. The sinking hole should be designed large or protruding, while the inner hexagonal only needs a small sinking hole.

Hence, actual application conditions and environment determines what type of screw must be used.

How to Maintain All In One Solar Street Lights

Generally speaking, all in one solar street lights do not need much maintenance after being installed, because all in one solar street lights is a very mature technology. But the operation/working environment has a great impact on outdoor solar lighting, Different installation site needs different maintenance accordingly. For example, in Africa, we should consider not only high temperature but also dust. Then we analyze some common maintenance problems from the following aspects:

  • The influence of dust

The influence of dust is mainly directly can be seen on the solar panels, because the dust will mainly affect the solar panels’ absorption of sunlight radiation, thus affecting the solar panels’ power generation efficiency. Normally, daily regular cleaning is no need because rainwater washes away the dust attached to solar panels on rainy days, but in some particularly arid environments or regions, rainwater is very few. Users can clean the solar panels regularly according to the actual situation, such as once a quarter, or once a year, depending on the rain and dust conditions of the installation site.

self-cleaning solar street light

  • Snow and its shelters

In some countries, winter snowfalls very long and heavy, or some lamps are installed near tall trees. Snow, leaves and bird droppings may be attached to solar panels. When there is a decrease in power generation efficiency, such as a decrease in the number of continuous rainy days or a shorter light-on time, which reminders they need to be cleaned up. Look at these shields.

 

  • Battery Maintenance

Usually, do not need to do special maintenance or replace batteries during the service life if they use high-quality & reliable batteries. According to our previous experience, LED light source and solar panel generally do not need to be maintained after the service lifetime, but the performance of the battery may decline after five years, so if the service lifetime exceeds, the lamp is still working, but the number of continuous rainy days has decreased significantly, we can consider replacing the battery for adding another life cycle.

 

  • Salt Corrosion

If the lamp is installed near the seashore or in places of heavy corrosion with high salt fog, the installation bracket should be inspected regularly. We suggest that the installation bracket be inspected once a year, depending on the actual situation of the installation site. Normally, no additional maintenance is required.

 

Generally speaking, integrated solar street lamps require little maintenance unless they are installed in harsh environments.

Solar Powered Street Lights Pay Back vs Grid. -LUXMAN

After 10 years’ development and practice, LED street lighting technology has become very mature and stable. About five years ago, another new type of solar Powered Street Lights appeared in people’s eyes. It is All in One Solar Powered Street Light. This kind of street light does not need to connect to the power grid, does not need electric wires, compact design, simple to install, and easy to maintain. In recent years, more and more people have paid attention to the product, especially in some areas where the power grid is not accessible, or in countries and regions with high electricity costs.

Solar-Powered-LED-Street-Light

The All in One Solar Powered Street Lights is the third generation solar street lighting product developed from the ordinary solar street lamp. After the development of battery technology and practical installation in recent years, the all in one solar LED street lamp technology has become very stable, so what is the return on investment vs Grid LED Street light?

Suppose a 5KM road with lights on both sides, 30 meters apart, and the lamp power is 40W, the pole 6 meters high.

  • 167 street lamps are installed on each side of the road, a total of 334units.
  • The load flow of cable of traditional street lamp trunk line in 4 and 5 kilometers road is I=P/U=333*250/220=377A, which requires copper core cable with a cross-section of 90mm². The unit price is 32USD/m2(Including labor cost). The cable cost is 32USD*5000m=160,000.00USD, Each lamp pole needs 12M 1.5 square electric wires, and the cost is 12M*334*0.5=2004USD
  • Each Grid LED street lamp needs to be equipped with an air switch to prevent short circuits, switch and facilitate maintenance. A total of 334 air switches are required. Then the total cost of the air switch is 2USD*334=668USD
  • This section of grid LED street light needs one distribution box with an internal time controller, control lights on and off, air switch, over-current & overload protector, watt-hour meter and so on. The total cost of 900USD requests.
  • The labor cost is 43USD per person per day, based on the cement road. According to our experience, with six workers, the all in one solar street lamp needs about 2 weeks of installation time, 10*6*43USD=2580USD, while grid street lamp needs about 3 weeks because of the connecting electric wires and other reasons, depending on the efficiency of the workers, the cost is not yet including car rental fees.
  • The following calculation is based on LUXMAN 5-year warranty all in one solar Powered Street Lights. Because of stable quality and LUXMAN will pay any cost of the after-sales problems, so this calculation is not included in the after-sales maintenance cost.

What Is the Best Solar Street Light In China

There are many other countries and regions in the world. Electricity is very scarce or expensive. In addition, global warming has caused more and more people to pay attention to green energy. In order to solve environmental problems and achieve environmental targets in Australia, some coal-fired power plants in Australia will be closed down. The government is also formulating relevant guidelines.

Subsidies for solar street lamps have multiplied in recent years in Africa due to power shortages. Based on these factors, solar energy-related products have become the choice of more and more people, and the best solar street light with induction has become one of them. As an ordinary consumer, you may want to know, what kind of solar-powered motion lights is the best solar powered street lights? We will analyze it from the following three aspects.

 

   1. Adopted good material

Best solar street lights must be made of good raw materials. The components that make up the solar street lamp are solar panels, solar cells, solar controllers, infrared sensors and so on. These core components will have a great impact on the life of solar street lamp products, such as the use of poor quality. Batteries will lead to very serious attenuation or even extinction of lamps after several months of use. So the best solar powered motion lights must use superior source material.

    2.Stability product system

As mentioned above, the best solar powered motion light must be made of good raw materials, so if a light is made of good raw materials, is it a good light? The answer is No. In fact, you can understand that the solar street lamp is a small solar power generation system. During the day, the photovoltaic module made of polycrystalline silicon converts solar energy into electric energy and stores it in storage batteries. Under the control of the intelligent controller, the solar street lamp absorbs the sun through the solar illumination. Energy and light are converted into electricity, and solar cells are charged to batteries during the day. In the evening, the battery pack provides power to the LED light source to realize the lighting function. The controller plays a vital role in the process of charging and discharging. The intelligent controller is written into the program group. Intelligent settings are made for lighting time and mode. If these programs are abnormal, it will affect the stability of the whole solar powered motion lights. In addition, different processors also affect the performance of the product. An important factor, such as the welding process of parts, the error control of hardware processing, etc., so a good solar Induction street lamp must be produced by a manufacturing factory with technological research and development strength and experience.

    3. Low maintenance cost

Whether as a professional or ordinary consumer, we are very concerned about the ROI index. Because of the cost of raw materials, the first purchase cost or investment of solar Induction street lamps is relatively high,

ItemSolar Light AC LightRemark
Power60W60W
Product cost$310.00*100=31,000.00$100.00*100=10,000.00
Electrical bills060/0.8*12*365/1000=328KWH

328*0.3USD*100=9800USD

We take 100PCS 60W solar street lamps as an example, do not consider Electric wires cost, Electric equipment cost and labor cost of AC light,  The solar street lamp can catch up with the pre-investment cost of non-solar street lamp products in the second year, so if the life of the solar-powered motion lights is unstable, it is a waste of investment.
