What factors hinder the large-scale development of solar street lights?

The popularity of solar street lights is becoming more and more widespread, but we all know that not all regions are suitable for the development of solar street lights, so what is hindering the energy-saving equipment of solar street lights? 1. Not only the cost is high, but it is also limited by natural factors. At present, there are two shortcomings in the use of solar street lights. One is that due to its high cost and large one-time investment, this is encountered in the promotion process. Common big problems; Second, as a natural energy source, solar energy is limited by natural factors such as illumination and weather, which also restricts the development of solar street lights to a certain extent. Second, the illumination range is narrow. In addition, since the general illumination range of solar street lights is 6-7 meters, it will be dim beyond 7 meters, which is not suitable for tunnels, urban main roads and other places with high requirements for illumination. At present, it is mainly suitable for On narrower roads with two lanes. 3. Difficult to achieve scale effect If you are familiar with solar power generation, we will know that the conversion rate of solar panels is very important for the reason why solar panels can convert the light energy of the sun into electricity. At present, there are two types of solar panels: polycrystalline silicon and monocrystalline silicon. The conversion rate of the former is not as good as that of the latter, but it is superior in terms of cost performance. However, these enterprises are all assembled with imported foreign raw materials. There are almost no enterprises capable of producing monocrystalline silicon and polycrystalline silicon panels in China. Domestic solar photovoltaic enterprises are generally small in scale, making it difficult to achieve economies of scale. For details, please visit: http://www.chz-lighting.com .
