7 Useful Tips For Choosing High-quality Solar Street Light In China

The quality of solar street light on the market is uneven,how to correctly choose solar street lamp?Exc street light,as a leader in solar street light manufacturing in China,will share 7 tips for choosing high-quality solar lamp.

Before choosing, we should first understand the composition of solar street light.

Composition of Solar street light

Solar street light are mainly composed of the following 4 parts:

Solar panels

Solar panels are divided into monocrystalline silicon and polysilicon.Monocrystalline silicon conversion efficiency is high, polysilicon conversion efficiency is lower than that of monocrystalline silicon.But when it comes to power, 100W monocrystalline silicon and 100W polysilicon are the same concept, but polysilicon is a bit bigger.

Battery energy storage

Battery energy storage are divided into traditional lead acid colloid maintenance free battery and lithium battery.

Lead-acid battery, conventional battery, life cycle of them is not as good as lithium battery, at the same time they has memory, can not discharge 100%, only 75% discharge depth, now not recommended.

Lithium batteries are divided into lithium iron phosphate batteries and three lithium batteries.Lithium iron phosphate batteries must be more expensive than three lithium. The use is the same, ternary lithium batteries are recommended here.

Why not recommend iron lithium, because the price of iron lithium is 1/3 higher than three yuan lithium.On the market, as long as solarenergy is made of iron lithium, iron lithium general is dismantling batteries, old batteries.Only the use dismantling batteries can ensure the price, but life can not be guaranteed.So,when you see that lithium iron is cheaper than lithium three, you know that it must be a disassembly battery.

Controller

Different manufacturers, the quality of the controller will be different.Big brands will also have problems, it mainly depending on the assembly plant's scheme mastery degree.

Lamp shell

The lamp shell material includes die-casting aluminum material and ABS plastic material. The lamp shell of die-casting material has better quality and is resistant to typhoon.

Solar street lamp scheme classification

light control scheme

In the traditional scheme, the lamp is on all the time.Now,after 1 or 2 hours, adjust the time control to half power, and then change the power after a while, so that the battery life of the lamp can be extended under the premise that the hardware indicators are not up to standard.

Human body sensing scheme

People come, 100% light on;people go, 10% light on.

Categories of solar street lamps

5~15W induction type small street lamp, this lamp for human body induction, cost-effective.Of course, many businesses advertise is 20W, 40W, 60W, which are deceptive.How can a small solar panel produce 60 watts of electricity, when it can actually do 20 watts, more higher will be overloaded.

20~50W induction street lamp, this lamp for human body induction. Real power, configuration increased, thus used in rural requirements for long endurance, low cost.

20~80W all in one solar street light, this lamps is commonly for exports, easy to install, save the cost of manual installation.

7 useful tips for choosing high-quality solar street lamps

Solar street lamp cap is also LED lamp cap, its shell thin and thick is a factor, the structure of aluminum plate, aluminum plate these structures, compared to the size and thickness of these things can basically determine the quality of the lamp cap.

Whether the battery is the solar street lamp special battery, now there are many small companies use the starting power for the energy storage battery, which will greatly damage the life of the solar street light.

Solar street lamp pole is hot dip galvanized plastic spray or cold galvanized plastic spray?Hot dip galvanized has coating on the notch, cold dip galvanized has no coating on.The life of hot-dip galvanized lamp post is generally more than 20 years, and the life of cold galvanized lamp post is generally about 1 year.

As long as master the above identification methods of solar street light quality,customer will buy high-quallity solar street light of China.
