Solar street lights are a typical case of new energy applications. It is not only energy-saving and environmentally friendly, but also beautiful, and can enhance the image of the city. In addition, solar street lights are more economical. Such a good product should be promoted in theory, but it is not the case. The penetration rate of solar street lights in China is still very low. Professional manufacturers of high pole lights analyze the reasons for the low penetration rate of solar street lights from a professional perspective?
1. Solar street lights have low brightness
The first is the brightness of solar street lights. Solar street lights only rely on the sun to generate electricity, and the conversion rate of solar panels is only about 19%. The power limit is destined to not be able to carry out high-power lighting, so the brightness must not be compared with the power source brightness.
2. Solar street lights are expensive
Solar street lights have more solar panels, batteries and controllers than ordinary street lights. The cost price is certainly not low, about 2 to 4 times that of ordinary street lights. Although it can be returned in about 5 years, sometimes it cannot be calculated in this way.
3. The battery life of solar lithium battery is short
All solar lithium batteries will not last long. This is caused by the technology of the street lighting industry. It needs to be replaced after about three years. Therefore, most street lamp manufacturers have a three-year warranty. If the battery is broken, solar street lights will also make a qualitative leap.
Although solar street lights have many limitations, they are not hidden. In recent years, they have gained popularity. It is estimated that the output in 2020 will be around 20 million baht, which is quite common compared with developed countries. There is still a gap. Jiangsu Qiandu Lighting will also actively develop technology to make our street lights in the forefront of the times.
