How to select a good quality solar street light

release time:2020-08-03        Views:         【Back to list】

Nowadays, rising demand for solar street light increases the market of solar light product. In order to make profit, more and more different quality products deriving in the market. Some supplier mark the light 200w which actually in 70-80W with lifespan months only. Therefore, we are wondering how to choose a good quality solar street light as well as competitive price. Here let us talk and try to find the answer. 

 

What is a Solar Street Light?

A solar street light is a street , parking lot or area light that is fully powered by solar energy.   Using a battery plus photovoltaic panel, it charges during the day and turns on at night. They come in a large variety of shapes and sizes with optional features such as motion sensors and remote controls. They can be used for complete projects or to add lights where is difficult to wire.

Compared to old-fashioned street lights, solar street lights have an edge on the competition because they offer the following perks:

 

  • Easy installation, &easy to replace old lights

  • Wider installation choice - anywhere

  • Low maintenance

  • Smart control, no labor or electronic control is required

  • Optimum lighting

  • Renewable energy source

 

solar street lights seem like the most ideal replacement for regular street lights. It no need offer electricity. Solar panel can convert solar directly into electricity and save it in the battery to use in mid night or bad weather.

Different with common led light , solar lighting pay more attention to battery and solar panel. Because it always controlled by smart lighting , that is full light at first and half light at mid night.

People care more about if it can be light on without power and how long it can last . Stability is the always first. Therefore, we should think about the solar panel and battery when we choose a solar street light.

 

1. Solar panel:

• Monocrystalline solar panels

• Polycrystalline solar panels

• Amorphous solar panels

 

Monocrystalline panels seem to be the most effective. Its efficiency rate goes up to 22 percent. But it is most expensive. Polycrystalline solar panels efficiency rate is more than 16 percent while the cost is much competitive. Amorphous solar panels is cheapest but the lowest cell efficiency rate which is not suitable for wide road and areas.

 

Not only the material of solar panel but also the panel size influence the light. For example, 1m*1m panel and 0.5m*0.5m, there are 2 times difference for solar panel to work from solar to electricity.

 

2. Battery:

1) Lead Acid Batteries. – These types of lights are easily available in market. But disadvantage is their life span is less and needs regular maintenance. Voltage required for charging is 12 Volts.

 

2) Lithium ION batteries – These types of lights comes with motions sensor, and are more efficient with life span of 4 -5 years. Voltage requirement for charging is 3.7 volts.

 

3) Lithium Iron Phosphate Batteries(LiFePO4) – It has motion sensor and intelligent sensor. These types of have battery life span of 7 -9 Years and capable of charging even in rainy days and the voltage it requires in 3.2 volts.

 

3. Mutual influence from solar panel and battery

For example, big size good quality solar panel with poor small capacity battery, the light will be dark and turn on for short time. Small size solar panel or low quality solar panel with big capacity battery, the light works no good either. The battery may never be full of power.

So, quality panel and quality battery should match and offer enough power to the LED chip.

So, quality panel and quality battery should match and offer enough power to the LED chip.

 

All our solar street light use our own produce battery and solar panel.

LiFePO4 battery( Life span:8-12years)

Polycrystalline solar panels(Lifetime:25 years): stable quality as well as competitive price, 19% conversion efficiency.
