As all in one solar street light market continue to grow rapidly with more than 25%, more and more companies are start to provided different solar led street light solutions, some of those companies provided very good and high quality products, but unfortunately most of companies started to introduce to market some very cheap and low quality products, Those product look nice and practically, but if you scratch beneath the surface and study their technical specifications in more details, you will notice that those product are completely not sufficient for optimal working conditions and to provide expected life cycle of life of all in one solar street lights which is minimum 2 years.
Poor quality is probably the main reason why more and more clients around the world do not trust in use solar led street light, 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 best 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.
In this article, Belinda will try to explain why is very critical to choose high quality components for all in one solar street light solution.
The components of all in one solar street light are the LED chips, battery, controller and solar panel, and the price and cost of solar led street light truly depends on the components.
First : All in one solar street light Battery type
The main cost of the solar street lights is the battery. And the cost of the battery take part about 15% to 20% cost of the whole solar lights. So battery quality is the most important thing for solar lights purchasing.
When you want to buy solar led street light, you may ask, should I choose a Ternary Li-ion battery or LiFePo4 battery, what is the cost, 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 electric car（D-class）, but over 90% Solar street light manufacturer 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,, offer 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 suggest 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, 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 we choose 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, high capacity, which can increase the solar panel Efficiency , could offer enough power for bearing power and is an ensurance 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 controller: PWM and MPPT in the market.
All in one solar led street lights adopts 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 our smart MPPT controller to PWM controller, the whole solar street light efficiency increased 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 decay in 5 years and more than 80% brightness remained.
110lm/w: Brightness decay in 2-3 years and about 20% brightness remained.
Solar street light provided a high level of lighting output with more than over160 lumens per watt which enabled our solar street light looks bright.
Fifth: All in one solar street light case and bracket material
Quality solar street light use customized die-casting aluminum mould, the advantages of die-casting aluminum mould are: light weight, strong and corrosion resistant , anti rust. Making it able to resist strong wind load of up to 130MPH that can last more than 25 years.
stainless steel screws are used as fastener to protect against any harsh whether. The die-casting aluminum mould is elegant and characteristics.
Lower quality solar street light just use mould and rough craft, the installing structure need support by knight head, to recover the structure strength issue, making install more complex, lack of stability and can not anti strong wind.
Also this metal case has IP66 protection level that enable clodesun solar street light operate in a 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, 70°C inside the solar lamp body. (we have tested )
Hot will damage battery and LED source, so we separate the hot solar panel and it has a shadow, makes solar street light cool, enlarge lifespan of battery and LED source.
Seventh: Whether All in one solar street light solar panel can adjust
Different countries and regions have different geographic locations and latitudes. When people install solar street light 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 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 low conversion rate of solar and the using areas are also limited.
The top solar street light Manufactures and suppliers are already implementing many new design in order to improve all in one solar street lamp solutions ,one of the top solar street light Manufacturer and supplier in the world is Shenzhen based company Clodesun, that developed completely new design solar street light mode that use the best class battery and MPPT controller 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 allow 365 days of smooth operation.
We also provided 5 years warranty on all in one solar street light, we can offer this longer warranty as we are focus on using only high quality components from reputable products.
