the typical cases of solar street light is a new energy application. It is not only energy conservation and environmental protection, and beautiful, can improve the image of the city. In addition, the solar street light is more economic. Such a good product in theory should be promoted, but that is not the case. Solar street light penetration in China remains low. Professional manufacturer of light from a professional point of view, the author analyzes the reasons of low solar street light penetration.

1。 Solar street lamp brightness low first is the brightness of the solar street light. Rely on solar power generation solar street lamps, solar panels, the conversion rate of only 19%. Power limitation will prevent high power lighting, so the brightness cannot be compared with the power of brightness. Solar street lamps are very expensive. Solar street light more than ordinary street lamp solar panels, batteries and controller. Cost is not low, of course, about 2 to 4 times that of ordinary street lamp. Although it can be back in about five years, but sometimes I can't use this method to calculate. 3. Solar power lithium battery life is very short. All of the solar energy lithium battery will last long. This is caused by a street light industry technology. About three years need to be replaced. As a result, most of the street lamp manufacturers have three years warranty. If the battery is broken, solar street lamps will have a qualitative leap. Despite many limitations of solar street light, but they are not hidden. In recent years, they become more and more popular. It is estimated that 2020 output will be about 20 million baht, compared with the developed countries, it is quite common. Still a gap.
