Today's society is an energy society. With the increasing shortage of traditional energy, the application of solar energy has become more and more extensive, especially in the field of power generation, which has developed into a mature sunrise industry in just a few years, and solar street lights are also developing. On the "bright road" of socialism. How much do you know about it?

At present, one of the most important links restricting the application of solar power generation is the price. Take a two-way solar street light as an example, the total load of the two channels is 60 watts (conservatively estimated), and the battery panel needs about 160W, which is 40 yuan per watt. Calculated, the cost of the battery panel is about 6400 yuan, and the cost of the battery pack of about 180AH is also about 2000. The one-time investment cost of the entire street light is much higher than that of the circuit light. It can be said that the price is the main bottleneck in the application field of solar street lights.
