Analysis of the main factors restricting the development of solar street lights

With the increasing shortage of traditional energy, the application of solar energy will become more and more extensive, especially the field of solar power generation has developed into a mature sunrise industry in just a few years. 1: 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. Discharge for 7 hours per night and increase the reserved amount of the battery board by 20%) The battery board needs about 160W. Calculated at 30 yuan per watt, the cost of the battery board will be 4,800 yuan, plus the cost of the battery pack of about 180AH is also Nearly 1800 yuan, the one-time investment cost of the entire street lamp is much higher than that of the city circuit lamp, causing the main bottleneck in the application field of solar street lamps. 2: The service life of the battery should also be considered in the application of the entire street light system. The general battery is guaranteed for three or five years, but the general battery will be unsatisfactory after one year or even half a year. Some actual charging rates are It may drop to about 50%, which will definitely affect the normal lighting at night during continuous rainy days, so it is particularly important to choose a better battery.
