Some view about vertical solar led street light
Vertical solar led street light is a new solar lighting concept for street lighting. Because of its outstanding features, it is becoming more and more popular since 2019 especially in middle east countries where the regular solar panel is always affected by sand and dust in a short time. At present there are mainly three types of vertical solar PV poles on market,
The first one is CIGS vertical solar PV represented by company "HEI" whose headquarter locates in Austria. HEI is an esteemed company that started vertical solar pole a few years ago and their technology is based on CIGS solar cell. The cylindrical solar module produced by HEI has a very high finishing performance, while objectively speaking, there are some points that HEI may need to improve.
1 : From the present datasheet of hei products, the power of their solar panel is kind of small which is not able to generate sufficient power to meet the power consumption of led light per night. because of this issue, solar light head only can work with low watts which is much lower than the datasheet shows in order to work for full nights to conserve energy to extend the lighting hours.
2 : HEI is using the technology of CIGS solar cell which is very soft and has great bent performance. while the main issue of CIGS is its efficiency is not so good as silicon solar cell. The initial efficiency of CIGS is more than 22% at the beginning while its efficiency will drop fast by more than 30% after 4~6 months. That means the power generated will much less after half a year and this will affect lighting performance greatly.
Generally speaking, HEI vertical solar PV is a great product with a lot of innovation, it will be good if HEI can keep improving on lighting efficiency per watts if not easy to extend the power of vertical PV. So it can create a better lighting performance for high-end solar lighting projects.
The second one is the linkable hexagon vertical solar module represented by "AURORAS INNOTECH" which is the only legal manufacturer in China. Such vertical solar module adopts the mutual technology of monocrystalline solar cell and aluminum profile. This vertical solar module was designed as "building blocks" which was intended to allow the module can be easily installed on any poles as long as the diameter of the pole is within 155mm no matter the pole is round shape or square or conical.This cylindrical solar module named "Solarwrap" contains two main modules which are connected to each other by MC4 plugs. And each vertical PV module has 2 pairs of MC4 cables one of which is for input and the other pair is for output. This allows customers to get higher power of vertical PV modules easily by linking them one by one.
Solarwrap vertical solar module is a patented product by auroras innotech in China. Until now the quality & design of solarwrap is approved with great honor by many big clients after a long time test, Including signify（PHILIPS）, LIGMAN, SCHREDER, etc. There are a few companies that copy the design of Solarwrap in China, for example, Sun-free etc. Their production and promotion activity for vertical solar modules is an infringement without Auroras' authorization.
The third one is the conventional vertical design. To produce such pole, the manufacturer should attach the slim solar module to the steel pole when they produce it which means such a vertical pole is a complete unit. It must be protected well enough from its production to delivery until the final installation. If the solar panel is damaged, it is very complicated to repair the system. In another word, it is very hard to maintain, so suppliers should spend a lot of attention on its package, then customers will be happy.
Finally, vertical solar led street light is a new concept of solar lighting, it is developed for high-end projects, It is very important to choose a reliable manufacturer as your partner.
Differents of 3 types of solar led street light system
Such light is an combination of all new technology.It has the advantages of ALL IN ONE type and it avoids the disadvantages of split type. Lithium battery and solar controller built inside of the light fixture as well as led chip. only solar panel are seperated which allow customer to use different powers as project require. There are only two parts of such light, only solar light head + solar panel which are connected by universal MC4 plugs. Anyone can do this connection easily without any mistake. in some regions, there are many problem that battery are always stolen when put in groud. Because such the lithium battery are inside of light head,so it is very safe and nobody can steal it. This is a very big concern in some regions when customers consider about their project.
As we know your company is working on serious goverment project. so we believe all in one solar street light is not a good option for your project. split type is a reasonable option if you have good technicians. while there are so many different modles and competitors and quality of such type are very various.In my opinion this type will be out of date gradually.and all the light will be semi split. because it is very easy to install and have good performance in lighting.
Our company has been focusing on high quality solar products which are for commercial. We have supplying thousands full set of solar street lighting for UN in past years. For commercial solar lighting, it must has a big battery which can make light work 100% for 12 hours at least. Only with this specification, the light can work well even in winter or cloudy days. There are many low price products even some companies declare "high data" in their data sheet. so i really hope you will be able to tell which is real and which is not.
Now We have developed full range of Semi Split type which covers different powers from 20W to 150W. Our latest model is THOR, it is specially for high way. and it has a very big battey capacity which can allow light to work 24 hours with 100%. We can make the design for your project if you like.
What is cylindrical led solar led street light
At present, regular flat solar panel are adopted for all kind of solar led street lights on market, it has a good power and can meet most of projects' requirements. But in some cases, regular solar panel is not a good option, for example.
When led power is 80W or more, solar panel will need 200W, but size of 200W solar panel is huge size, the installation performance is very ugly.
In windy areas or countries, regular solar panel with big size is too easy to be blown off or damaged, It could be worse especially when typhoon or other very bad weathers.
In order to solve these problems, Auroras team spent months time and finally worked out cylinder solar led street light which is completed different from the exisiting solution on market. We are honored to introduce the world's first real modular cylindrical solar led street light solution! What are the advantages of this cylindrical solar street light? Actually there are many outstanding advantages as below:
With a slim solar tube on the pole, it has much better looking than using traditional solar panel. This design blends street lights with city very well and makes city more beautiful.
(Cylinder) Cylindrical solar street light is an great innovation in 2019, 6 slim solar panels are fixed on a hexagonal cylinder aluminum frame. It has a much stronger performance in wind resistant. and it makes the complete solar pole more beautiful than regular solar panel. Auroras's cylinder solar panel is a modular panel which can meet different power as requested.

Advantage & Disadvantage of All in One LED Street Light
Integrated all in one solar street light has become as an important role of outdoor lighting. It is getting more and more popular recent years. While Is it suitable for all demand and have good performance in all over the regions? which kind of solar light should you use? That is a good question!
The main reason why it gets more popular is for its compact design. The lithium battery and solar controller are built inside of light fixture, and solar panel are attached on the top of fixture. It is very easy to be installed at any places as long as there is sunshine. Can be installed on wall, kind of poles, or any other matersial which can be mounted. It is an very good choice to use this solar light to light up night for the places where is out or short of electricity. Normally there is a motion sensor which is in order to save power consumption: Light will work at 30% power when there is nobody and sensor is not triggered, and it will power up to 100% power which will last 20 ~60 seconds as program sets once sensor is triggered when someone passes by. AIO (All in one solar) street light is very suitable to be used for these countries or regions where there is plenty of sunshine all over the year, like most of middle east countries, South America, South Africa and some Asia countries.
A coin has two sides. There are some disadvantages because of the compact all in one design.
A: POWER LIMITATION OF SOLAR PANEL
The solar panel is locked tightly in the light fixture. so it cannot be modified easily to have a higher power in order to improve its lighiting performance. At moment on market, the solar panel is kind of too small comparing with its LED light power. For example, the LED power is 30W as rated power while the solar panel is only 40W or 45W. As we know the effective sunshine duration is only 5 hours around on average on the world. That will cause the problem that there is not enough power generated from solar panel to support led light to work with high power output for long time continuesly.Because of this reason, It is necessary to use the motion sensor for all models of such all in one solar street light in order to save energy.
(How to calculate the the power relation between solar panel and led light? check here.)
B: DIRECTION/ANGLE LIMITATION
Because of all in one design, the solar light is completely fixed on the top of light. it cannot be adjusted its angle or direction, That will cause two problems as below.
1: Solar panel of all in one model cannot be rotated to meet the best direction to make use of sunshine as efficient as possible. From the comparing picture as below, we can see there is NO any problem if we use HELIOS model, HELIOS's solar panel can be adjusted very easily and freely.

All in TWO Solar LED Street Light
Comparing on different latitude
All in One Solar LED Street Light All in TWO Solar LED Street Light
We can tell from above comparation, all in one solar street light is not an ideal even we can call "bad" choice if use it in such short-sunshine regions like England , Canada, Russia,etc. All in one solar street light is an good products for general application, but it also has many limitation. So we suggest that clients can choose the right solar street light accordingly. Auroras are producing rich models of solar light that you can choose from to meet all kind of outdoor solar lighting.

What is solar led batten light kit?
Solar led batten light is the pioneer model comparing with the normal solar powered tube light, widely used in many applications, such as office, home, garage, caravan, carports, bus stations, warehouses, camping tents, kinds of shelves, farm tents, sideways, emergency camps, aid tents, temporary or permanent caves, or any kinds of sheds of paths, etc.
Solar led batten light is a kit that contains everything, like rechargeable lithium battery, solar controller, solar panel. Easy installation in less than 15 minutes, you just need to plug solar panel into the light by DC connector. It provides a high brighttness for long time continuous lighting output, and inbuilt PIR sensor can save power if sunshine is not strong enough. This solar led batten light is also supported to work during day time while being charged, under manual operation. By programming the remote control, you can increase or decrease the brightness as you like, there are 2 hours, 4 hours and 6 hours for optional. Pressing the button on light, you will find out 3 lighting modes , brightness and time can be set easily by remote control.
One 5V USB output was added to charge your mobile, What's more , an external switch is allowed to be connected to this light via a DC port. The ON / OFF and brightness can be operated by hand just like the traditional lights. This is a very useful advantage for the applications which need to do the lighting operation by hand instead of automatic. It is a perfect lighting solution for the remote area where is lack of power and lighting.
What is the core factor for solar led street light?
From recent years, solar led street light is becoming more and more important and its demand has been increased a lot. There are more and more factories who start to product solar street light, There are various models of solar lights with different specification, and main problem is there is not a very clear standard of quality or specification to refer to.
So, how to compare the quality of different solar street lights and choose the right one for your project? What is the biggest concern that you need to focus when you compare? Our answer is light efficiency.
Comparison of All in One and All in Two Solar LED Street Light
A: 50W Solar LED Street Light
LED Quantity: 60Pcs Battery 600WH Solar Panel: 80W
B: 100W Solar LED Street Light
LED Quantity: 240Pcs Battery 900WH Solar Panel: 150W
Such two solar lights are both called “500W” while the efficiency is much different, All in one solar led street light is only working in 50% power actually, and its efficiency is about 3000lm~4000lm in energy saving mode. But B type with 240pcs led, our model can work well with 100% power and lumens is 8000lm. It is more than doubled than normal all in one solar led street light.
Auroras’s quality policy is to provide high lumens solar products for commercial lighting project, our latest model THOR are able to reach 160lm/w practically, 50W of THOR is able to provide 8000lm, that means THOR 50W is equal to normal 90W-100W models of normal solar led street light, This makes our solar light offer is very competitive than offering a higher power consumption solar light. Lower power , it means request smaller size battery and smaller size solar panel, so it reduce cost of whole project greatly. It will be much easier for end customer to accept an offer like this. Because the budget is there all the time
So when you select the solar lights for project application, lumens efficiency per watt is the most important concern , not the power led LED. We provides solar led street light from 2000lm to 18000lm as full range of solar lighting powers as optional.
We will reply to you within 24 hours once we get your inquiry.
Why we say there are some the fake data of solar light?
Many many customers asked such questions, especially some customers are very new to solar lights, As we know the competition of convential AC solar light is very bad, and very less profit for most of customers. Auroras is able to provide you good quality of solar led flood light, solar led street light and solar led batten light. So now we can see there are more and more customers start to engage into solar light.As far as we know. in our opinion, solar light is a very "deep" water products. before you start to try solar light, we suggest you should learn about these basic acknowleage about solar. and should know how to tell the quality and the specification from the supplier's data sheet. Until now, we have met many catalog or quotations sheet with very " amazing "data sheet which is very hard for us to believe.
For example, The data sheet for below solar light is
but our all in two solar led light, 30W we have 30AH 12V battery ,and 80W solar led panel. What is your idea when you see this data? from what it says, this light is very nice, and the price is also good, and you then maybe go to calculate the project quantity or expected their light performance as they say...When you receive the light, and you install there, the lumens you will say: wow, it is great, then you feel satisfied.. We must confess this is workable for some customers, especially for pravate customers who only expect it as a " decoration". Let's study above data in a professional way. About the battery. it does not mention the voltage. it maybe 3.7V 15A or 11.1V 15A. , btweeen these two data there are big difference. 3.7V 15A battery, it means the battery capacity is only 3.7*15=55.5WH, the power of this light is 20W, that means the light will only work 55.5WH/20W = 2.5 Hours with 100% power output.. so this light will work only in energy saving mode. it is 30% power only,means normally the power led light is only 5W or 6W only.So you may ask: What about lumens 3000lm? Their answer is: when the light is working with 100%, the lumens can reach 3000lm. Yes, they are right, but they will not tell you , such power only last 20 seconds, or 1 mins max!. and even you should accept the real answer is: 3000lm is only the max lumens of LED chip. CHIP, not complete light. There is big difference. That means the real lumens output will be only 2500lm around in a positive calculation.
Just now we talked about the battery, 3.7V, of course, they may use 6.4V 15AH, it should work well. But as a customer, you should know what you pay for. you are paying for A Audi Q5 or a cheap model. So it is very important to choose a good supplier to make solar led street light or all in one solar led batten light for you in a good and professional way.
How to calculate the power concumption of solar light?
There are many types of solar light on market like solar street light, all in one solar led batten light, or solar flood light.It is same way to calculate the power. While most of clients do not know how to judge whether the battery is matching with the lighting power consumption or not, then only can rely on the answer from salesman of suppliers. What's more, there is many salesman who answer clients' answer too facilely just in order to sell their products to client asap which causes a lot of compliant finally.
For example. for same power 30W solar led street light, why does some solar street light have battery 20AH, but why other all in one solar street light have 16AH? what makes the difference? which one suits your requests more? Let's learn it today.
How can i know the power consumption of your solar led batten light? or solar led flood light per night?
Let's take Helios all in two 30W solar led street light as example. So you will know how to decide it.
As the default setting, HELIOS 30W is working with 100% power for first 6 hours and 50% power for next 6 hours without sensor. Then theoretically the power consumption per night is :
30W*6H +30W*50%*6H = 270WH,
and we need to include the power consumption of system, it is about 5% around. so we can get the total consumption roughly is 270WH*(1+5%)=283.5WH.
That means only the power of battery capacity is more than 283.5WH, the light will work as the default setting, or the light will stop working earlier. How to choose and calculate the right battery capacity? Based on above calculation, the power consumption is 283.5WH, normally the system for 30W is 12V for the battery. So the battery capacity should be:
As we know the D.O.D (Depth of Discharge) of lead acid battery is 60-70% , so if this all in two solar led street light is using lead acid battery, the capacity should be: 12V 40AH (24/0.6=40). If lithium battery with D.O.D 100%, the battery capacity should be 12V 24AH. Normally Auroras always put more capacity as backup in order to extend lifetime of battery. So when the power is 30W, Auroras is using 36AH battery. In above example, if the lighting mode is 50% power for 12 hours with sensor function, the power consumption will be much less. As long as we know how to calculate it, we will know whether the specification is reasonable or not. So we need to choose the right battery capacity based on light consumption. No need to rely on supplier's description.
