Solar street lights are not new products. In general, the system includes street lights, solar panel, solar controller, batteries, arm, mast, cable, and so on.
Maybe some projects are in your town. You can save all the electricity costs and resources. It looks great. You might think that we should use solar street lights everywhere. But why are they not so popular?
1. Why not so popular now
The main reason is cost. When the powerConsumption of street lamps is 60 watts, it takes 150 to 170 watt solar panel and 2 pieces 80 Ah batteries. The cost is close to USD 1, 000 If the power consumption is higher, like 150 watts, will cost a bit surprising. Many countries can not accept the prize.
But as traditional HPS lighting is the electricity consumption typically 60W, 80W, 150W, 250W or 400W. Thus, the costs are high in most cases. Many countries can not accept the costs.
2. LEDTechnology
In the past two years, LED street lamps are increasingly popular. They use LED (Light Emitting Diode) as light sources. Compared with conventional HPS lamps, LED lamps can save up to 50% -70% energy. For example, you can replace 30W, 60W, 110W and 160W LED lamps, 80W, 150W, 250W and 400W lamps.
3. Advantages of LED street lights
The main advantages are as follows
1). Low power consumption
2). Higher power efficiency - LED streetlightsexcess mercury vapor is 31 lm / W. They can be more effective by measuring found for high-pressure sodium lamps. It is simply confusing because it includes wasted light, which in turn wastes energy. In the market, many power efficiency of LED street lamps, up to 80lm / W.
3). More lux per watt - more than twice as high as a mercury vapor street light. The corresponding measurement for high-pressure sodium lamps is of "hot spots" distorted that the bump lead lux rating, but not desirableVisibility, security and glare problems.
4) Longer life (50,000 hours)
4. Why Solar LED street lamps will be very popular
Because LED bulbs are energy saving, it can reduce cost of kits. If the cost is low, many countries can be accepted.
For example, can, 60W solar LED street lights replaced the traditional 150W HPS street lights. It stores all the electricity. If you calculate ROI, you will notice that there are more than 30% in two years. Why notaccept?
In addition, the LED is the semiconductor industry. The efficiency rises rapidly. The cost of the solar system be less in the future.
Thus, lamps with solar-LED kits are the perfect combination. They are very popular in the future 3 years.
