What Is Solar Powered Street Lights?-LUXMAN Light

/in , /by

With global warming, green energy has become a trend. Solar-powered street lights with 100% green energy come into being, so what is solar-powered street lights? Solar street lamps are mainly composed of solar panels, controllers, LED light sources and batteries.
During the day, solar panels absorb energy from the sun and convert it into power, which is stored in solar batteries by the controller, and provide lighting power for an LED light source at night. This is the working principle of solar street lamps work.

What Factors Affect All in one solar led street light lifetime

/in /by

All in one solar led street light has many advantages, so it can be widely installed and used, such as no electricity fees, no wire laying cost, and so on. But because the first purchase cost of all in one solar street light is higher than the ordinary AC LED street lamps in terms of unit price, we need to purchase stable quality. Long-life solar street lights, let our investment get a stable return.

So let’s analyze what factors will affect the life of a solar street lamp. We will analyze them from the following three main aspects.

  • Operation environment conditions

The working environment of lights has a vital impact on lifetime, especially outdoor solar street lights. Some main environmental impact factors are temperature, humidity, dust, and so on. Why does temperature affect the solar street lamps’ lifetime? Because solar street lamp batteries are sensitive to environmental temperatures, such as the ambient temperature of lithium ternary batteries can not exceed – 20 C – 40 C, LUXMAN seldom uses such batteries, but chooses lithium iron phosphate batteries, because their operation ambient temperature can reach – 10 C – 60 C.  due to Solar Street light used for outdoor places, so the water-proof performance of the lamp is very important, otherwise, it will lead to controllers, batteries and other core devices into the water, thus directly extinguishing the lamp.

  •   Material Selection

Solar panels, batteries, and controllers are the three core parts of the solar street lamp, especially the battery part. If we choose some core components which are not of good quality, it will seriously affect the lifespan. We often hear customers’ feedback from us that a large number of solar street lamps purchased from a merchant has failed in 2-To 3 months, usually, this situation is due to the manufacturer’s selection of bad materials.

  •   Operation Time

This will not happen much compared with solar street lamps, because solar street lamps are usually used at night and do not work too long.

So if you want to buy a solar street lamp product with stable quality, please choose a regular manufacturer. In addition, before purchasing the product, tell your supplier what kind of environment the solar street lamp product you purchased will be applied to. Let them consider the environmental impact factors in advance and customize the product for your project.

Solar Powered Street Light

How long do solar powered street light last in 2024？

/in /by

The life of high-quality solar-powered street lights can exceed 10 years. In the past, the life of street lights was only 3-5 years, because of the use of lead-acid batteries or other short-life batteries. Now solar lamps generally use lithium iron phosphate batteries, which have a life of more than 10 years. The latest CATL era batteries can already have a life of up to 16 years. Its life impact is mainly due to the short life of some components, especially batteries, followed by light source controllers and solar panels. Now let’s analyze these components, which will mainly affect the life of solar street lights.

solar-powered-street-light

Lighting source:

Now the solar street light usually uses the LED light source. After years of technological development, the life of the LED light has been stable. The good quality led light can theoretically reach 50,000 hours, 10 hours a day, and can be used for more than 10 years. After years of the practical application of LUXMAN, the outdoor LED light can be achieved more than 10 years of lifetime.

Batteries:

Batteries are more complex. Besides operation temperature and waterproof performance, the types of batteries are also the key factors affecting the life of LED solar street lamps. For example, the cycle times of ordinary lithium-ion batteries are about 500-600 times, while that of lithium iron phosphate batteries(LiFePO4)can be about 3000 times, which will influenceLED solar street lamps lifetime, LUXMAN solar street lamp provides three-year quality assurance because of adopting the LiFePO4 batteries. According to our practical application over the years, it is found that the actual life of the solar street lamp using LiFePO4 batteries can totally reach 10 years lifetime. Especially now, the latest battery life of the Ningde era can be used for 16 years

Solar panels   

After years of development, solar panels have become a very mature technology, with a service life of more than 20 years.

Solar Controller: 

The controller provides controlling, monitoring, protection of the battery, and working status of the load, etc. The controller adopted now is a constant current integrated controller, which integrates drive and control as its name implies, and can be used for 8-10 years.If this is properly maintained and replaced, it can continue to be used.

 

Through the above mentioned, a solar street light adopted good quality material with good performance, the lifespan can reach 10 years, and the key component affecting the life of solar street lamp is a battery. But now the latest battery life of the CATL can be used for 16 years, and later solar lamps can live longer.

Solar Street Lights 5 Kinds Applications -LUXMAN LIGHT

/in /by

As we know Solar Street light has the following benefits:

* Installation anywhere

* Maintenance-free

* No underground or overhead service

* No electricity bill

* Different styles available

* Mobile phone remote control

* Real-time 24 hours of surveillance and security function optional

 

From the above advantages of solar-powered street lights, it can have a wide application, so in what areas can all in one solar light be applied?

Solar-Street-Light-Applications

1st– Remote Areas

Such as rural roads, islands, military barracks, farms and so on, because these places are remote or inhabitants do not live centrally, so the laying of electric wiring is very difficult, the cost of laying wiring is not proportional to the utilization rate, so solar pole lights can be used in remote areas.

2nd – Construction Site

Because these are temporary places, so access to power or installation of lighting is inconvenient, LUXMAN once had a customer who bought LUXMAN all in one solar street lights is leased to large local builders.

3rd – Campus, Square

Generally, these places are very empty, have a better sunshine foundation, on the other hand, the flow of people in these areas will be more during 6pm-10pm, and later will be reduced a lot, solar streetlight sensing and timing control functions well meet this demand characteristics.

4th – Road and Street

This application is also the most important application, street light power consumption is usually relatively large, in some countries and regions, electricity is very expensive, if the solar street lamp can be used to replace ordinary street light or LED street light, then a huge cost will be saved.

5th Residential Areas

Solar street lamps have good mobility. Residents can install different places according to their needs, such as swimming pool, Party table, courtyard entrance, Parking lot, etc. In addition, the extension function of solar street lamps can also meet the needs of residents, such as camera monitoring function, USB charging, mobile phone APP operation function and so on, bring users a more convenient user experience.

Smart Street Light and 5G Micro Station

/in /by

China’s 5G license is issued one year ahead of schedule, so we can imagine the importance China attaches to 5G. Because 5G has been recognized as the fourth industrial revolution, one of the major application scenarios of 5G is intelligent driving and driverless and smart street lights. What impact and opportunities does 5G have on the company? What will 5G bring? Whether Smart street light can be the links of smart cities.  In June 2019, the issuance of 5G commercial licenses in China marked the acceleration of the 5G era.

5G station

It has three “netted, node, poled” micro-base stations, which are deployed in densely populated areas and buildings . It can effectively supplement the weak coverage area of macro-base station signals, and can achieve capacity improvement in a smaller range. The load-bearing design of ordinary lamp pole is difficult to carry the construction of 5G micro-base station. Every 100m of 5G network has a 5G micro-base station. The power consumption of 5G is three times of that of 4G. Loading 5G equipment on the basis of 4G macro-station often encounters insufficient power. Therefore, smart street lamp pole becomes the preferred equipment of 5G micro-base station.

 

Functional Realization of 5G SMART Light Pole

It can collect, distribute and transmit information of smart street lighting, public security, municipal administration, meteorology, environmental protection, communication and other industries, and form a smart perception network to realize the precise management of urban areas and intensive utilization of urban resources.

5G smart light pole

The Problems Faced by 5G Smart Street Light Pole to Achieve Popularization

  1. High cost

The cost of a smart street light with pole is usually about 4000-5000USD, and the 5G base station needs more than the 4G base station. In order to achieve the 5G response speed, the 5G base station construction will be at least twice as fast as the 4G base station, and the 5G base station cost will be twice as much as the 4G base station. The power consumption of the 5G base station is three times as high as that of the 4G base station. About 1.5 times that of 4G.

2. Cooperation of the Government

Because the base station involves the huge investment of government funds and the high challenge to municipal planning, it can not start this project in a short time without the full support of the local government.

  1. High requirements for the company’s comprehensive strength

Because 5G and intelligent lighting projects involve hardware, software, financial strength and company qualification requirements, ordinary companies are excluded. Only a few large companies have access tickets to the market.

What’s the Differences Between Monocrystalline solar panel and Polycrystalline solar panel ?

/in /by

Solar street lamps usually use two kinds of solar panels, Monocrystalline solar panels, and polycrystalline solar panels. Silicon is the raw material for making solar cells, but it is not easy to extract it. Therefore, while producing monocrystalline solar cells, people also studied polycrystalline solar cells. So how do distinguish monocrystalline solar panels and polycrystalline solar panel correctly?

Firstly: Appearance differences

Looking from the appearance, the four corners of the monocrystalline solar cell are circular, and the surface is not patterned; while the four corners of the polycrystalline cell are square, and the surface is like an ice flower.

                Polycrystalline solar panel

 

Secondly: Usage differences

For users, there is no big difference between monocrystalline solar panels and polycrystalline solar panels. Both of their life and stability are very good. Although the average conversion efficiency of monocrystalline silicon panels is about 1% higher than that of polycrystalline silicon panels, monocrystalline silicon panels can only be made into quasi-square (all sides are circular arcs), some areas of solar panels will not be filled when they are made up; while polycrystalline silicon is square, so there is no such a problem, their advantages, and disadvantages.

Analysis On Street Light Electric Shock Caused By Heavy Rains

/in /by

Every summer during the rainstorm season, news of casualties caused by street light electric shock accidents occurs. Most of the Electric Shock of Street Light caused by light electric leakage on rainy days. Due to the high temperature and humidity of street light facilities in summer, the cable insulation layer is easy to aging and breakdown, leading to electric leakage. In addition, thunderstorms Street light Leakage Accident occur frequently in summer, it forms water accumulation on roads, which immerses urban lighting facilities (such as cable wells, street light poles, etc.) in water and easily causes electric leakage accidents. The leakage of the street light pole may occur in the following ways.

led street lightstreet light

  • The poor quality construction causes leakage of lighting facilities.

Failure to comply with the standard construction or installation quality problems, such as screw damage to the insulation layer of street light cables during installation. In rainstorm days, when urban rainwater soaks live equipment, it will cause the connection equipment live. Leakage caused by rainwater immersion.

street light poles LUXMAN - LED Street Light Pole

  •   The aging and damage of the cable insulation layer in the lamp pole make the lamp pole live.

Some construction simply uses a tape winding method, the tape is easy to aging, it is likely to leak electricity.

  • The poor quality of lighting electrical appliances causes the lamp pole to be electrified.

In the design and construction of urban lighting engineering, strict checks should be made on the selection of lighting appliances, the selection of certified light sources, electrical appliances, lamps, and other products should be a priority.

  • Discharge of wiring terminals.

At present, most of the wiring connection modes are peeling and winding. This mode has high resistance, high current, short heating life of terminals, and will discharge when moisture or water is immersed.

  • The electricity of the lamp pole caused by man-made destruction.

It mainly refers to the cable which was stolen and damaged, cable fracture exposed to the lamp pole, and this easily leads to discharge accidents.

  • The harsh natural environment causes the lamp pole to be charged.

Because of thunderstorms, water overflowed the repair door holes, resulting in street light leakage. Or lightning strike on the lamp pole, because the lamp pole grounding is not good, resulting in burning electrical equipment so that the lamp pole around to be charged.

At present, more and more solar street lights used for roadway lighting, which completely solved the leakage accident. In addition to urban main roads, major facilities, buildings, large squares and other places such as secondary roads, residential roads, parking lots, parks, schools, hospitals, and so on, all of these places can consider the use of solar street lights. In addition, in some natural disaster-prone areas, such as flood areas and earthquake-prone areas, solar street lights are also a good choice because these disasters are easy to cause line damage and leakage.

The Influence of Average Annual Sunshine And Total Solar Radiation Intensity In Africa For Solar Street Light

/in /by

LUXMAN specializes in the production of solar LED street lights. Before each project is carried out, the customer’s environment and application will be investigated. Factors such as longitude and latitude, sunshine intensity, installation height of solar street light, installation location, estimated human flow, working hours per night, whether to accept intelligent dimming, etc. Will be considered and recommended. In this way, we can offer the best solutions, provide suitable products and fantastic services to our customers.

  1. Average Annual Sunshine in Africa

From a longitude and latitude point of view, Africa spans 30°N〜30°S. In average annual sunshine, the general trend is more in the north and south of Africa, and less in the middle. North of Sahara Desert, the annual sunshine is 3 000 ~ 3 500 hours. It’s lower in the central Africa, Gulf of Guinea and Congo Basin, at only 2 000 ~ 2 500 hours per year. It’s higher in the south of Africa, about 2 500 ~ 3 500 hours per year. Between 10° N ~ 10° S, the annual sunshine hours in the East are higher than in the West. For example, Somalia, Ethiopia and Kenya average 2 500 ~ 3 500 hours per year, while Liberia, southern Nigeria, Congo and Democratic Congo in the West average 2 000 ~ 2 500 hours per year.

Due to the control of the tropical continental Saharan air mass in northern Africa, the climate is dry and sunshine is abundant. The annual sunshine in Egypt, Algeria, Libya, Mauritania, Niger, northern Chad and Northern Sudan at 10°〜30°N is more than 3,000 hours. Western Africa is affected by the Equatorial Ocean Air Mass and it has less sunshine. From Sierra Leone to Central Africa and Democratic Congo, the annual sunshine is 2,000 to 2,500 hours. Affected by the dry northeast monsoon and the changeable southeast monsoon in East Africa, the climate is dry and sunshine is abundant throughout the year. From southern Sudan, Ethiopia, Somalia to northern Mozambique, the annual sunshine increases to 2 500 ~ 3 000 hours.

Southern Africa is controlled by the subtropical highs in the Atlantic and Pacific Oceans. It has  stable air, less rain and more hours of sunshine, especially on the West coast. It’s particularly obvious. Southern Zambia, Angola and Mozambique have relatively less sunshine than in the south, ranging from 2500 ~ 3 000 hours per year. In an area centered in Botswana, the annual sunshine is more than 3000 hours. At the east coast of South Africa, it’s about 2 500 hours per year.

  1. Annual Total Solar Radiation Intensity

The annual total solar radiation intensity is 6 300 ~ 6 700 MJ/m2 in the Mediterranean coast of Africa. With Sahara as the center extending eastward to Sudan, Ethiopia, Somalia and Eastern Kenya, and Northern Tanzania, it’s about 7 500 ~ 8 400 MJ/m2. From the Gulf of Guinea in West Africa to Congo and Zaire, it’s about 5 800 ~ 6 700 MJ/m2. The rest of Africa is mostly at 6 700 ~ 7 500 MJ/m2.

Key words: solar street lights us, hurricanes, rainstorms, floods, earthquakes, etc.

According to the U.S. World Daily, the weather forecast pointed out that Oklahoma and Arkansas were affected by the latest storm on the 27th, possibly the worst flooding in history. In Arkansas, the river water level has risen sharply and is on the verge of flooding.

In Tulsa, Oklahoma, the Army National Guard stepped up patrols on the dikes that were in danger. Tulsa Mayor G.T. Bynum said on the 27th that the levees are still normal, but the situation may change at any time. “We call on everyone to prepare for the worst floods in history.” Billam said people living near the embankment should evacuate early, and the city government has set up a number of shelters.

everlasting lampnatural disaster

Every year, floods hit the Midwest and Great Plains. Over the past 30 years, the federal government and local governments had invested about $5 billion in flood prevention budgets. Over the past 10 years, costs have increased gradually, as several densely populated areas, including Texas, New York and New Jersey, have been hit hard by storms. The central and western regions have suffered from the devastating storms. Strong winds and floods have left the disaster areas devastated.

Lithium iron phosphate batteries (LiFePO4 battery) or Ternary lithium battery ?

/in /by

How to choose a solar street light battery?

As we all know, more and more people are buying integrated solar street lights, and one of the keys points of the Solar Street Light quality is the selection of solar street light batteries. Usually, we use Ternary Lithium batteries or LiFePO4 batteries. Let’s compare the difference between the two.

LUXMAN - solar battery manufacturer

First of all, why we use lithium batteries?

Lithium batteries (Li-ion, Lithium Battery): Lithium batteries are widely used because of their advantages of a lightweight, large capacity and no memory effect. The energy density of lithium batteries is very high, and their capacity is 1.5-2 times that of Ni-MH batteries of the same weight. (SYLVANIA solar street lamps adopted Ni-MH batteries) Lithium also has a low self-discharge rate. In addition, lithium batteries have few “memory effects” and no toxic substances, which are also important reasons for their wide application.

32700 battery

Ternary Lithium batteries and LiFePO4 batteries are the two main types of Lithium Batteries that are used for Solar lighting products.

Ternary lithium battery Vs lithium iron phosphate battery

I:  The material system of a LiFePO4 battery and a ternary Lithium battery is different.

II:  A LiFePO4 battery is a 3.2V voltage platform, with a cycle life of more than 2000 charges.

III:  The ternary lithium battery is a 3.7V voltage platform, and the cycle life depends on different manufacturers, different models, and processes, and generally, it is 500-800 charge cycles.

IV:  LiFePO4 batteries offer better high-temperature performance, while ternary lithium batteries have better low-temperature performance.

V:  LiFePO4 solar street light batteries are safer.

Further analysis of the two kinds of lithium batteries,

LiFePO4 batteries are characterized by high safety, high rate charge-discharge characteristics and long cycle life. The battery capacity is 80% of the initial capacity after 1600 cycles when the charging condition is 1C multiple charging to 3.65V, then the constant voltage is changed to 0.02C, and then the discharge voltage is 2.0V at 1C multiple charging to 2.0V cut-off voltage. LiFePO4 batteries also have stable charge-discharge characteristics and good fast charge characteristics. In addition to its long life and excellent charge-discharge performance, the greatest advantage of LiFePO4 batteries is their safety. The chemical properties of liFePO4 batteries are stable and the high-temperature stability is good. The LiFePO4 batteries begin to decompose at 700-800 C, and will not release oxygen molecules in the face of impact, needling, short circuit, and so on. It will not produce intense combustion and has high safety performance

32700 battery cell

The disadvantage of a LiFePO4 battery is that its performance is greatly affected by temperature, especially in a low-temperature environment, where the discharge capacity and capacity will be greatly reduced. In addition, there are some performance defects in lithium iron phosphate. The energy density of the battery is low, only the weight energy density of the battery is 120Wh/kg. If the energy density of the whole stack, including the battery management system, heat dissipation, and other components is calculated, it will be lower. The cost of material preparation and the cost of battery manufacturing are higher, the yield of the battery is low and the consistency is poor. The cost per pack is higher than that of ternary lithium batteries

Ternary lithium batteries refer to lithium batteries containing transition metal lithium-intercalated oxides containing nickel, cobalt and manganese, which can be expressed as LiMnxNiyCo1-x-yO2 (0 < x < 0.5, 0 < y < 0.5). This material combines the advantages of lithium cobalt oxide, lithium nickel oxide, and lithium manganate, and forms a ternary synergistic effect of three materials, whose comprehensive properties are superior to any single combination compound. Weight energy density can reach 200Wh/kg

The safety of ternary lithium batteries is poor. The thermal stability of ternary lithium batteries is poor. They will decompose at 250-300C. When it encounters flammable electrolytes and carbon materials, decomposition will start at a point. The heat generated will further intensify the decomposition of the positive pole, and it will deflagrate in a very short time. In a car accident, the impact of external force can damage the battery diaphragm, which will lead to a short circuit, and the heat generated during the short circuit will cause the thermal temperature to rapidly rise to more than 300 C, creating the risk of spontaneous combustion. Therefore, for ternary lithium batteries, the battery management system and heat dissipation system are very important.

From the solar street light battery knowledge above, you can know whether the light purchased is a high or low-quality version.

If you purchase Integrated solar LED street lamps only marked “Lithium battery”, you have to know it uses LiFePO4 batteries or other Lithium batteries. Most of the time it will be ternary Lithium batteries. If it is ternary lithium power, do not expect a five-year service life guarantee.
