The streetlight is now very close to us, but rarely to pay attention to it, until it illuminates the scope and suddenly filled with darkness, we only pay attention.


  Today, we are around the street, for those around us with the most solar lights.

As a child we can often see this in the textbook "Our basic necessities can not do without the sun, the sun gives us light and heat." Indeed, the sun has given people a lot of things, while people are constantly on the development and utilization of the sun. Because the sun there are many equipment, solar water heaters, solar power plants, solar water pumps, solar lights and so on.



  Solar lights, by definition, by the composition of solar energy and light, more precisely, should be by the battery panels, batteries, controller components of the three systems. In contrast, solar street lighting system components to be more complex. Solar street light is mainly used in the light source is LED, DC energy-saving lamps, DC gas discharge lamp and electrodeless lamp.

  Before the power shortage in western regions, for example, the majority of rural power supply users are away from the grid, residents scattered residence, and high-voltage transmission construction costs of 10-13 million per kilometer, resulting in the cost of setting up power lines is high. The power grid is mainly used to meet the rural residents living and production of electricity, the most important of which is lighting, small appliances, and agricultural irrigation. For public facilities such as road lighting, with or without, with the solar photovoltaic technology matures, in many solar photovoltaic power generation is considered to be the best way to solve the problem of rural power generation.


  In the city, the road on both sides of the public facilities lighting and building lighting is a lot of money to spend, and every day need to spend, the emergence of solar street lights greatly alleviate the urban public facilities with large expenditure, high energy consumption problems.



  Solar street lighting daytime photovoltaic power generation in the battery, the night for the street lamp battery power supply, play a role in lighting. It does not require the laying of cables, do not consume conventional energy, energy saving, easy installation and other advantages of the community has been widely recognized.



  But for many people holding a negative attitude, they seem to solar street lights to "energy saving" as the main selling point of the system, which itself has a great waste of resources configuration problems. Why do you say this way?



  In most of the conditions of use, solar cells and power storage devices are idle, not only the inevitable high cost of the system, but also with the system itself to the performance of energy-saving and comprehensive use of the theme is also run counter to. Solar cell life, battery life and other control components are often lower than the life of LED life problems, likely to result in relatively high maintenance costs.



  Future prospects of how solar street lights like it? The answer is yes, from the economic point of view, according to estimates, to 4 meters and 8 meters street lamp calculation, the use of solar street lights, 4 meters and 8 meters annual street lamp to save about 2190 kwh electricity, electricity savings of 1533 yuan, or Has a good income space, from the energy saving point of view, it’s electricity from photovoltaic power generation, do not need to consume traditional energy, energy saving, pollution-free. But the above-mentioned problems are also hindering the expansion of the main reason for its market, we understand that many companies are also through technological innovation to improve the existence of solar street lights these problems.



  I believe the future of solar street lamp industry as a result of the more obvious social and economic benefits, but also by the support and promotion of multi-party, solar street lamp market size or will show rapid growth trend.
