What problems should solar street lights overcome in order to become a mature sunrise industry?

At present, 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, increase the panel by 20% (calculated by the China Solar Energy Industry Alliance Network), the panel needs about 160W, and if calculated at 30 yuan per watt, the cost of the panel will be 4800 yuan, plus a battery of about 180AH. The cost of the group is also around 1800. The one-time investment cost of the entire street lamp is much higher than that of the city circuit lamp, which has caused 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. 3: Some engineering companies often choose LED lights as the lighting of solar street lights, but the quality of LED lights varies, and LEDs with serious light decay may attenuate 50% of the illuminance in half a year. Therefore, it is necessary to choose LED lamps with slow light decay, or use electrodeless lamps, low-pressure sodium lamps, etc. 4: The choice of controller is often a problem ignored by engineering companies. The quality of the controller varies. The market price of the 12V/10A controller ranges from 100-200 yuan, although it is the least valuable in the entire street light system. part, but it is a very important part. The quality of the controller directly affects the component life of the solar street light system and the procurement cost of the entire system.
