Advantage and Disadvantage of All-in-One LED Street Light

To talk about the advantages and disadvantages of all in one solar powered street light, let us use briefly the working principle for solar PV products at first. Solar PV product is taken sunlight as energy, its solar panel absorbs solar radiation power in daytime, to convert solar power into electric power, and to store into battery under the function of solar controller. In night, according to its setting program, solar controller controls battery to discharge for electric appliances.

Components of all in one solar street light

LED light source

Lithium battery

Solar panel

Controller all together in one piece.

Special Features Of all in one Solar Street Light

We can very alter its programming very easily. Let me explain you with the help of an example..!

If the sky is dark, this all-in-one solar street light lights up automatically. If the sky is bright then these lights power off automatically. And hence, saves the energy!

At the point when individuals approaching, the light will work with full power mode in 100% splendor. At the point when individuals leave, the light will swing to vitality spare mode with 30% brilliance.

1 Work with half shine for the first hour

2 Then gives 100% shine for the second third hour

3 It work with half shine for the fourth hour

4 Then work with 10% shine for the fifth twelfth hour

Mainly applications of all in one solar street lights

This all in one solar street light runs with solar energy, it is simple to maintain and guarantee the performance

Here are the main applications of all in one solar street light:

Urban streets

Expressways

Country streets

Town streets,

Parks, gardens

Beautiful district

Other open spots

The advantages of all in one solar powered street light

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. It can be installed on wall, kind of poles, or any other material 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.

1 Simple installation: Do not require any external power cable and connection. It can be installed individually, no need excavate hole, burying lines, backfilling and saving construction cost. This system is can be installed within few minutes.

2 All in one solar powered street light can realize full-automatic control, no need personnel management, to save management cost.

3 Lithium battery: It has a longer lifespan because of a lithium battery.

4 There is no need to purchase power capacity increase device, to save cost of the relevant devices.

4 It is powered by sunlight, not to consume conventional energy, to save operation cost.

5 It is easy to maintain, it wouldn’t have electric shock accident, very safe to use.

6 Modern design: All of its parts have a modern design with standardized production. LED, Solar Controller, Battery can be restored very easily.

The disadvantages of all in one solar powered street light

1 Its comprehensive efficiency is directly influenced by local sunlight intensity, it can’t meet requirement of these areas where have insufficient sunlight condition.

2 Its solar panel needs to be radiated directly by sunlight, it shouldn’t have any shadow to cover, its accurate installation site would be limited.

3 Under regardless of construction, operation and maintenance cost condition, its initial investment is a little of high.

4 Power limitation

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 lighting 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 continually. 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.

5 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.

a Solar panel of all in one model cannot be rotated to meet the best direction to make use of sunshine as efficient as possible.

b Solar panel of all in one solar street light can not be adjusted in .As we know, the solar panel horizontal direction should be different based on different latitude, normally it is 0 degree to 45 degree, With proper angle to sun, it will get the max using  efficiency of solar panel.

We can tell from above contrast, all in one solar street light is an good products for general application, but it also  has few limitations. So we suggest that clients can choose the right solar street light accordingly. Tachyonlight are producing rich models of solar light that you can choose from to meet all kind of outdoor solar lighting. Welcome to contact us.
