Don’t just look at the solar street light parameters only
When we buy quality solar streetlights, we must not just look at the specifications advertised by the suppliers. Because the battery that the supplier may advertise is 100Ah, the actual product purchased is only 10Ah. Even with the same capacity, the available capacity of batteries of different grades is different. For the same solar street light, some suppliers label 60W, and some may label 300W.
The solar street lighting system is very different from the traditional utility city street light, such as in terms of the power of LED lights, You may often see 300W and 500W power solar street light systems in the market, As we all know, a 300W solar street light work 12 hours need power is 3600WH every night, so the power of solar panels need at least 800W. This is undoubtedly an unreasonable configuration for a solar street road system, especially an all-in-one solar street light.
Cheap & low-quality solar street lights= Waste of Money
People want to buy the cheapest products, but the cheap ones do not mean the most cost-effective. It also depends on the effect and longevity. For example:
With the 10 years lifespan of a $300 high-quality solar light, the average annual cost is $30.
with the 1 year lifespan of a $100 poor-quality solar light, the average annual cost is $100. If it is broken, it is a waste of time and energy cost, which is actually not worth it.
To get more business, some greedy manufacturers produce low-quality products with shoddy standard parameters, causing a large number of performance issues which lead to many people opting for electric street lights instead of solar street light products.
Some customers lost faith in Chinese products. They think that Chinese products break easily. Here’re some of the “horror stories” I’ve personally known over the years.
How to distinguish the difference between good quality and poor quality solar street lights.
First: Solar street light Battery life
A-class LiFePO4 Lithium> B-class LiFePO4 Lithium>Ternary Li-ion Lithium> Broken Lithium detached from the electric car（D-class）, over 90% of Solar street light manufacturers use broken lithium battery which is detached from Electricity car, lifespan less than one year.
If you want to buy high-quality solar street lights, Belinda suggests you choose an A-class A-class LiFePO4 battery or a B-class Lifepo4 battery, Although their cost is higher than other batteries, their lifespan will be extended by more than three to five years. if you need to install solar street lights in places where the sun is not particularly sufficient, we can also choose to use a Ternary lithium battery.
Second: Solar street light Solar panel size
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 the insurance of brightness and longer backup time during cloudy days.
But the low-quality solar panel size configuration is less than two and a half times the load power. If the cloudy days exceed more than expected design requirements, the led light would not work.
Third: Solar street light Solar panel size LED Chip Lumen
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.
Fourth: Solar street light Solar panel size Case and Bracket Material
Quality solar street lights use a 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, 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 knighthead, to recover the structure strength issue, making installation more complex, lack of stability, and can not anti strong wind.
Fifth: Whether heat Dissipation between solar panels 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.
Six: Whether Solar street light Solar panel size solar panels can adjust
Different countries and regions have different geographic locations and latitudes. When people install solar street lights someplace, 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 low conversion rate of solar and the using areas are also limited.
