Solar Street Lights Are Coming
Solar LED Streetlights are not new products. Usually, the system contains street lamps, solar panels, solar devices, batteries, arm, pole, wires and so on.
You might find some projects in your city. They can save all the electricity costs and resources. It looks good. You might think we should use sunlight everywhere. But why aren't they that popular?
1. Why not so popular now
The main reason is cost. The cost is close to $1,000,000. If power consumption is higher, for example, 150 Watts, the cost will be a bit amazing. Many countries cannot accept the price.
But as traditional HPS street lights, energy consumption is usually 60W, 80W, 150W, 250W or 400W. So the cost is high in most cases. Many countries cannot accept the cost.
2. LED technology
Over the past two years, LED streetlight manufacturer become more and more popular. They use light-emitting Diode (LED) as light sources. Compared to traditional HPS lights, LED lights can save 50% -70% energy. For example, 30W, 60W, 110W and 160W LED lights can replace 80W, 150W, 250W and 400W HPS lights.
3. Advantages of LED street lights
The main advantages are the following
1). Lower energy consumption
2). Higher power output - LED street lighting exceeds mercury vapors 31 lm /W. You can find higher efficiency measurements from high-pressure sodium lamps. It is only misleading because it contains wasted light that in turn wastes energy. On the market, many power efficiency of LED street lighting up to 80lm/w.
3). More Lux per Watt - more than twice as much as a mercury vapor street light. The equivalent measurement for high-pressure sodium lamps is skewed by hotspots that encounter the lux degree but cause unwanted visibility, safety, and glare problems.
4) Longer life (50,000 hours)
4. Why solar LED Outdoor street lighting will be very popular
Because LED lights are energy saving, it can reduce the cost of solar energy.
For example, 60W LED street lights can replace traditional 150W HPS street lights. It saves all the electricity. Why not accept?
In addition, LED is in the semiconductor industry. Efficiency is increasing rapidly. The cost of solar panels will be lower in the future.
