Clodesun launched a foldable design All in one Solar Street Light in 2021, which are designed by our German team for more than 1 year and tested for 2 years. This light stands out among various integrated solar street lights. It is widely praised by customers all over the world.
As the in-one solar street light market continues to grow rapidly with more than 25%, more and more companies are starting to provide different solar-led street light solutions, some of those companies provided very good and high-quality products, but unfortunately most of the companies started to introduce to market some very cheap and low-quality products, that product looks nice and practical.
But if you scratch beneath the surface and study their technical specifications in more detail, you will notice that those products are completely not sufficient for optimal working conditions and to provide the expected life cycle of life of all in one solar-led street light which is less than 2 years even one year.
Poor quality is probably the main reason why more and more clients around the world do not trust in use solar led street lights, For example, the governments of Iraq and Nepal ban the installation of solar led street lights, because their governments have been very disappointed with the quality of solar street lights.
Admit it: finding the top-quality all in one solar led street lights on the market isn’t exactly the easiest thing to do nowadays. As a matter of fact, there are so many companies that make solar street lights out there, which can make it super hard to figure out which one is the right one for you.
Clodesun will try to explain why is critical to choose high-quality components for solar-led street light solutions.
The components of solar-led street light are the LED lamp, battery, controller, and solar panel, and the price and cost of solar-led street light truly depend on the components.
First: All in one solar street light Battery type
The main cost of solar street lights is the battery. And the cost of the battery takes part about 15% to 20% of the whole solar lights. So battery quality is the most important thing for solar lights purchasing.
When you want to buy integrated solar led street light, you may ask, should I choose a Ternary Li-ion battery or LiFePo4 battery, what is the cost, and how can I choose, well, you are not alone, 95% of solar street light Customer will ask this same question.
From the comparison table above:
A-class LiFePO4 Lithium> B-class LiFePO4 Lithium>Ternary Li-ion Lithium> Broken Lithium detached from the electric car（D-class）, but over 90% of Solar street light manufacturers use the broken lithium battery which is detached from Electricity car, the lifespan less than one year.
Although A class LiFePO4 battery is more expensive than Ternary Li-ion Lithium, offers significant advantages, including improved discharge efficiency, longer life span, and the ability to deep cycle while maintaining performance and its chemical substance inside is more stable, which makes it kind of high-temperature resistance.
If you want to buy high-quality solar street lights, Belinda suggests you choose A class A-class LiFePO4 battery or B class Lifepo4 battery, Although their cost is higher than other batteries, their lifespan will be extended by more than three to five years. So, if your project is in the tropics, a LiFePO4 battery is recommended. But if the project is in northern countries, we advise ternary lithium battery.
Second: All in one solar street light solar panel size and class
Why do we choose a Monocrystalline solar panel? By selecting a monocrystalline solar module, Solar-led street Lighting International knows it will produce more energy, work better in high temperatures, and last longer than a polycrystalline panel, We build these with our end-users in mind – you want a budget-friendly product that will last and that is what we provide.
And the wider solar panel size means Large load power, and high capacity, which can increase the solar panel Efficiency, could offer enough power for bearing power, and is an insurance of brightness and longer backup time during cloudy days.
But the low-quality solar panel size configuration is less than two and half times load power. If the cloudy days exceed more than expected design requirements, the led light would not work.
Third: All in one solar street light smart MPPT solar charge controller
There are 2 types of controllers: PWM and MPPT in the market.
All in one solar led street lights to adopt a smart MPPT controller, for, in this case, PWM will waste some energy collected by panels, while MPPT can convert all the solar energy collected into chemical energy and this smart MPPT improves battery life and provided the efficient service throughout the whole year.
Compared to our smart MPPT controller to PWM controller, the whole solar street light efficiency increased by about 30%.
Fouth: All in one solar street light LED chip lumens
What is “ >160 Lumens per watt ”? Why does this matter? Because we produce more light, using less power than our competitors.
6,400 lumens – This is our entry-level fixture.
12,800 lumens – is our medium-based selection when you need that extra amount of light.
19,200 lumens – is for the client that requires the very best. A light designed for large areas or a multiple-lane roadway.
Remember watts don’t matter – lumens do! Lumens tell you how much light you can expect from the light fixture, watts just tell you how much power it consumes. The higher the lumen per watt ratio, the better and brighter a system you can expect.
210lm/w: Brightness decayed in 5 years and more than 80% brightness remained.
110lm/w: Brightness decayed in 2-3 years and about 20% brightness remained.
Clodesun solar street light provided a high level of lighting output with more than over160 lumens per watt which enabled our solar street light to look bright.
Fifth: All in one solar street light case and bracket material
Quality solar street lights use customized die-casting aluminum mold, the advantages of die-casting aluminum mold are lightweight, strong and corrosion resistant, and anti-rust. Making it able to resist a strong wind load of up to 130MPH that can last more than 25 years.
stainless steel screws are used as fasteners to protect against any harsh weather. The die-casting aluminum mold is elegant and characteristic.
Lower quality solar street lights just use mold and rough craft, the installing structure need support by knight head, to recover the structure strength issue, making installation more complex, lack of stability and can not anti strong wind.
Also, this metal case has an IP66 protection level that enables clodesun solar street light to operate in severe weather conditions
Sixth: All in one solar street light heat Dissipation new design between solar panel and light
In summer, the solar panel is as hot as 90°C, and 70°C inside the solar lamp body. (we have tested )
Hot will damage the battery and LED source, so we separate the hot solar panel and it has a shadow, makes solar street light cool, and enlarge the lifespan of the battery and LED source.
Seventh: All in one solar street light solar panel can adjust
As we all know. In the northern hemisphere, the sunshine rises from the south, but in the southern hemisphere, the sunshine rises from the north.
That is why we need to design solar panels to fold and unfold in order to ensure the solar panel face the sun on both sides of the road,
In the northern hemisphere, we can unfold on the north side of the road, fold on the south side of the road
In the southern hemisphere, we can unfold on the south side of the road, fold on the north side of the road
And different countries and regions have different geographic locations and latitudes. When people install solar street lights in some place, on one side, the solar panel can face the sun directly, but on the other side, the solar panel can not face the sun,
so if the solar panel can be adjustable, it will absorb more solar energy, which can maximize the conversion of solar energy while the lower quality solar led street light panel is fixed, causing a low conversion rate of solar and the using areas are also limited.
The best all-in-one solar street light manufacturers and suppliers are already implementing many new designs in order to improve solar street light solutions, one of the top all-in-one solar street light manufacturers and suppliers in the world is a Shenzhen-based company CLODESUN.
Clodesun developed a completely German new design integrated solar street light mode that uses the best class battery and MPPT controller with high efficiency, monocrystalline solar panel, smart MPPT (Maximum Power Point Tracking) charge controller, > 160 lumens per watt adjustable LED modules, a long life LiFePO4 battery, microwave sensor control that allows 365 days of smooth operation.
We also provided 5 years warranty on all one integrated solar street light, we can offer this longer warranty as we are focused on using only high-quality components from reputable products.
